Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

For me it was due to full disk space.

My application (server) was running on docker. Cleared some space and it started working.

I was trying to set my Ionic 4 app to run as a pwa. When I run the command:

ng add @angular/pwa

...got the error message. After some try and error I discovered that when my project was created the start command was wrong. I was using an Ionic 3 version:

ionic start myApp tabs --type=ionic-angular

And the correct is:

ionic start myApp tabs --type=angular

with no 'ionic-' in type. This solved the error.

The problem is in the font-weight.
For Font Awesome 5 you have to use {font-weight:900}

To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.

protected override void OnConfiguring(DbContextOptionsBuilder options)
        => options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");

To use the EF core SqlServer provider and compile the above code install the EF SqlServer package

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

After compilation before running the code do the following for the first time

dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update

To run the code

dotnet run

Removed and added back in the table using Scaffold-DbContext and the error went away

I did this by going to setting>Keyboard Shortcuts then in the section where it give a search bar type focus terminal and select the option. It will ask to type the combination which you want to set for this action. DO it. As for editor focus type" editor focus" in the search bar and type your desired key. IF you excellently add a key . it can be removed by going to edit jason as mentioned in above comments

For scoop users:

"terminal.integrated.shell.windows": "C:\\Users\\[YOUR-NAME]\\scoop\\apps\\git\\current\\usr\\bin\\bash.exe",
"terminal.integrated.shellArgs.windows": [
  "-l",
  "-i"
],

Simply. You can go to 'File -> Preferences -> Color Theme' option in visual studio and change the color of you choice.

If you want to change the external terminal to the new windows terminal, here's how.

A picture is worth a thousand words !

The concept of Angular is very simple. It propose to "build" an app with "bricks" -> modules.

This concept makes it possible to better structure the code and to facilitate reuse and sharing.

Be careful not to confuse the Angular modules with the ES2015 / TypeScript modules.

Regarding the Angular module, it is a mechanism for:

1- group components (but also services, directives, pipes etc ...)

2- define their dependencies

3- define their visibility.

An Angular module is simply defined with a class (usually empty) and the NgModule decorator.

like Jesse Jesse Glick and abguy said you can enumerate string into Boolean type:

Boolean.valueOf(string_variable)

or the opposite Boolean into string:

String.valueOf(boolean_variable)

in my case I had to to downstream Boolean parameter to another job. So for this you will need the use the class BooleanParameterValue :

build job: 'downstream_job_name', parameters:
[
[$class: 'BooleanParameterValue', name: 'parameter_name', value: false],
], wait: true

When I tried these steps I kept getting error:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Then i looked at event viewer and saw this error:Unable to install counter strings because the SYSTEM\CurrentControlSet\Services\ASP.NET_64\Performance key could not be opened or accessed. The first DWORD in the Data section contains the Win32 error code.

To fix the issue i manually created following entry in registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance

and followed these steps:

1. Search for "Turn windows features on or off"
2. Check "Internet Information Services"
3. Check "World Wide Web Services"
4. Check "Application Development Features"
5. Enable all items under this

Thanks for all the answers. I tried all of them but none of them worked for me. What did work was to delete the applicationhost.config from the .vs folder (found in the folder of your project/solution) and create a new virtual directory (Project Properties > Web > Create Virtual Directory). Hope this will help somebody else.

In version 3 of a Docker Compose file, you can use RESTART.

For example:

docker-compose.yml

worker:
    build: myapp/.
    volumes:
    - myapp/.:/usr/src/app:ro
    restart: on-failure
    depends_on:
    - rabbitmq
rabbitmq:
    image: rabbitmq:3-management

Note that I used depends_on instead of links since the latter is deprecated in version 3.

Even though it works, it might not be the ideal solution since you restart the docker container at every failure.

Have a look to RESTART_POLICY as well. it let you fine tune the restart policy.

When you use Compose in production, it is actually best practice to use the restart policy :

Specifying a restart policy like restart: always to avoid downtime

Visual Studio 2015 does include Xamarin Starter edition https://xamarin.com/starter

Xamarin Starter is free and allows developers to build and publish simple apps with the following limitations:

• Contain no more than 128k of compiled user code (IL)
• Do NOT call out to native third party libraries (i.e., developers may not P/Invoke into C/C++/Objective-C/Java)
• Built using Xamarin.iOS / Xamarin.Android (NOT Xamarin.Forms)

Xamarin Starter installs automatically with Visual Studio 2015, and works with VS 2012, 2013, and 2015 (including Community Editions). When your app outgrows Starter, you will be offered the opportunity to upgrade to a paid subscription, which you can learn more about here: https://store.xamarin.com/

I just experienced this same issue, trying to enable CORS globally. However I found out it does work, however only when the request contains a Origin header value. If you omit the origin header value, the response will not contain a Access-Control-Allow-Origin.

I used a chrome plugin called DHC to test my GET request. It allowed me to add the Origin header easily.

There is an option to clear passwords

If you have the generated SSH key for your project from GitLab you can add it to your keychain in OS X via terminal.

ssh-add -K <ssh_generated_key_file.txt>

Once executed you will be asked for the passphrase that you entered when creating the SSH key.

Once the SSH key is in the keychain you can paste the URL from GitLab into Sourcetree like you normally would to clone the project.

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

Sub Module for Connecting to MS SQL with Remote Host & Username/Password

Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String

'Setup the connection string for accessing MS SQL database
   'Make sure to change:
       '1: PASSWORD
       '2: USERNAME
       '3: REMOTE_IP_ADDRESS

    'Opens connection to the database
    cnn.Open ConnectionString
    'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
    cnn.CommandTimeout = 900

To begin - there are 4 issues that could be causing the common LocalDb SqlExpress Sql Server connectivity errors SQL Network Interfaces, error: 50 - Local Database Runtime error occurred, before you begin you need to rename the v11 or v12 to (localdb)\mssqllocaldb

Possible Issues

• You don't have the services running
• You don't have the firelwall ports here configured
• Your install has and issue/corrupt (the steps below help give you a nice clean start)
• You did not rename the V11 or 12 to mssqllocaldb

 \\ rename the conn string from v12.0 to MSSQLLocalDB -like so-> 
 `<connectionStrings>
      <add name="ProductsContext" connectionString="Data Source= (localdb)\mssqllocaldb; 
      ...`

I found that the simplest is to do the below - I have attached the pics and steps for help.

First verify which instance you have installed, you can do this by checking the registry& by running cmd

 1. `cmd> Sqllocaldb.exe i` 
 2. `cmd> Sqllocaldb.exe s "whicheverVersionYouWantFromListBefore"` 
if this step fails, you can delete with option `d` cmd> Sqllocaldb.exe d "someDb"
 3. `cmd> Sqllocaldb.exe c "createSomeNewDbIfyouWantDb"` 
 4. `cmd> Sqllocaldb.exe start "createSomeNewDbIfyouWantDb"`

ADVANCED Trouble Shooting Registry configurations

Edit 1, from requests & comments: Here are the Registry path for all versions, in a generic format to track down the registry

Paths

// SQL SERVER RECENT VERSIONS
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\(instance-name)

// OLD SQL SERVER
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSSQLServer
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
// SQL SERVER 6.0 and above.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSDTC
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SQLExecutive
// SQL SERVER 7.0 and above

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SQLServerAgent
HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft SQL Server 7
HKEY_LOCAL_MACHINE\Software\Microsoft\MSSQLServ65

Searching

SELECT registry_key, value_name, value_data  
FROM sys.dm_server_registry  
WHERE registry_key LIKE N'%SQLAgent%';

or Run this in SSMS Sql Management Studio, it will give a full list of all installs you have on the server

DECLARE     @SQL VARCHAR(MAX)
SET         @SQL = 'DECLARE @returnValue NVARCHAR(100)'
SELECT @SQL = @SQL + CHAR(13) + 'EXEC   master.dbo.xp_regread

 @rootkey      = N''HKEY_LOCAL_MACHINE'',
 @key          = N''SOFTWARE\Microsoft\Microsoft SQL Server\' + RegPath + '\MSSQLServer'',
 @value_name   = N''DefaultData'',
 @value        = @returnValue OUTPUT; 

 UPDATE #tempInstanceNames SET DefaultDataPath = @returnValue WHERE RegPath = ''' + RegPath + '''' + CHAR(13) FROM #tempInstanceNames 

 -- now, with these results, you can search the reg for the values inside reg
 EXEC (@SQL)
 SELECT      InstanceName, RegPath, DefaultDataPath
 FROM        #tempInstanceNames

Trouble Shooting Network configurations

SELECT registry_key, value_name, value_data  
FROM sys.dm_server_registry  
WHERE registry_key LIKE N'%SuperSocketNetLib%';  

I had the same issue.

Make sure that In SQL Server configuration --> SQL Server Services --> SQL Server Agent is enable

This solved my problem

Integrated Security and User ID \ Password authentication are mutually exclusive. To connect to SQL Server as the user running the code, remove User ID and Password from your connection string:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;"

To connect with specific credentials, remove Integrated Security:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; User ID = $uid; Password = $pwd;"

In my situation, the Oracle 11.2 32-bit client was installed on my 64-bit Windows 2008 R2 OS.

My solution: In the Advanced Settings for the Application Pool assigned to my ASP.NET application, I set Enable 32-Bit Applications to True.

Please see below for the standalone .ashx test script that I used to test the ability to connect to Oracle. Before making the Application Pool change, its response was:

[Running as 64-bit] Connection failed.

...and after the Application Pool change:

[Running as 32-bit] Connection succeeded.

TestOracle.ashx – Script to Test an Oracle Connection via System.Data.OracleClient:

To use: Change the user, password and host variables as appropriate.

Note that this script can be used in a standalone fashion without disturbing your ASP.NET web application project file. Just drop it in your application folder.

<%@ WebHandler Language="C#" Class="Handler1" %>
<%@ Assembly Name="System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" %>

using System;
using System.Data.OracleClient;
using System.Web;

public class Handler1 : IHttpHandler
{
    private static readonly string m_User = "USER";
    private static readonly string m_Password = "PASSWORD";
    private static readonly string m_Host = "HOST";

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";

        string result = TestOracleConnection();
        context.Response.Write(result);
    }

    public bool IsReusable
    {
        get { return false; }
    }

    private string TestOracleConnection()
    {
        string result = IntPtr.Size == 8 ?
            "[Running as 64-bit]" : "[Running as 32-bit]";

        try
        {
            string connString = String.Format(
              "Data Source={0};Password={1};User ID={2};",
              m_Host, m_User, m_Password);

            OracleConnection oradb = new OracleConnection();
            oradb.ConnectionString = connString;
            oradb.Open();
            oradb.Close();
            result += " Connection succeeded.";
        }
        catch
        {
            result += " Connection failed.";
        }

        return result;
    }
}

It appears that you are using the default route which is defined as this:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

The key part of that route is the {id} piece. If you look at your action method, your parameter is k instead of id. You need to change your action method to this so that it matches the route parameter:

// change int k to int id
public ActionResult DetailsData(int id)

If you wanted to leave your parameter as k, then you would change the URL to be:

http://localhost:7317/Employee/DetailsData?k=4

You also appear to have a problem with your connection string. In your web.config, you need to change your connection string to this (provided by haim770 in another answer that he deleted):

<connectionStrings>
  <add name="EmployeeContext"
       connectionString="Server=.;Database=mytry;integrated security=True;"
       providerName="System.Data.SqlClient" />
</connectionStrings>

just and another class to jumbotron

bg-transparent

It will work perfectly

bootstrap color documentation: https://getbootstrap.com/docs/4.3/utilities/colors/

Just set Integrated Security=False and it will work ,according to a comment difference between True and False is:

True ignores User ID and Password if provided and uses those of the running process, SSPI(Security Support Provider Interface ) it will use them if provided which is why MS prefers this. They are equivalent in that they use the same security mechanism to authenticate but that is it.

Try using Response.AddHeader instead of Response.Headers.Add()

List<T> equality does not check them element-by-element. You can use LINQ's SequenceEqual method for that:

var a = ints1.SequenceEqual(ints2);

To ignore order, use SetEquals:

var a = new HashSet<int>(ints1).SetEquals(ints2);

This should work, because you are comparing sequences of IDs, which do not contain duplicates. If it does, and you need to take duplicates into account, the way to do it in linear time is to compose a hash-based dictionary of counts, add one for each element of the first sequence, subtract one for each element of the second sequence, and check if the resultant counts are all zeros:

var counts = ints1
    .GroupBy(v => v)
    .ToDictionary(g => g.Key, g => g.Count());
var ok = true;
foreach (var n in ints2) {
    int c;
    if (counts.TryGetValue(n, out c)) {
        counts[n] = c-1;
    } else {
        ok = false;
        break;
    }
}
var res = ok && counts.Values.All(c => c == 0);

Finally, if you are fine with an O(N*LogN) solution, you can sort the two sequences, and compare them for equality using SequenceEqual.

Add this in your web.config file

<connectionStrings>
<add name="itmall" 
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-
02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
</connectionStrings>

My simple way, but it can help for further variations on this subject. List all methods and alter them to useless.

  Object.getOwnPropertyNames(console).filter(function(property) {
     return typeof console[property] == 'function';
  }).forEach(function (verb) {
     console[verb] =function(){return 'Sorry, for security reasons...';};
  });

It worked for me.

1. Open command prompt
2. Run "SqlLocalDB.exe start"
3. System response "LocalDB instance "mssqllocaldb" started."
4. In VS, View/Server Explorer/(Right click) Data Connections/Add Connection
   • Data Source: Microsoft SQL Server (SqlClient)
   • Server name: (localdb)\MSSQLLocalDB
   • Log on to the server: Use Windows Authentication
5. Press "Test Connection", Then OK.

Here's the solution using Phonegap Build. Add the following to your config.xml to be able to inspect with Chrome Remote Webview Debugging.

First, make sure your widget tag contains xmlns:android="http://schemas.android.com/apk/res/android"

<widget 
    xmlns="http://www.w3.org/ns/widgets" 
    xmlns:gap="http://phonegap.com/ns/1.0" 
    xmlns:android="http://schemas.android.com/apk/res/android"
    id="me.app.id" 
    version="1.0.0">

Then add the following

<gap:config-file platform="android" parent="/manifest">
     <application android:debuggable="true" />
</gap:config-file>

It works for me on Nexus 5, Phonegap 3.7.0.

<preference name="phonegap-version" value="3.7.0" />

Build the app in Phonegap Build, install the APK, connect the phone to the USB, enable USB debugging on you phone then visit chrome://inspect.

use this connection string :

Server=HARIHARAN-PC\SQLEXPRESS;Intial Catalog=persons;Integrated Security=True;

rename person with your database name

I had this error and I found that the name of one of my connection strings was wrong. Check the names as well as the actual string.

The dll is missing in the published (deployed environment). That is the reason why it is working in the local i.e. Visual Studio but not in the Azure Website Environment.

Just do Copy Local = true in the properties for the assembly(System.Web.Http.WebHost) and then do a redeploy, it should work fine.

Gets the time to wait while trying to establish a connection before terminating the attempt and generating an error.

Normally i use a class for this:

public class ClassName
{
    public string Col1 { get; set; }
    public int Col2 { get; set; }
}

Now you can use a loop to fill a list and ToArray if you really need an array:

ClassName[] allRecords = null;
string sql = @"SELECT col1,col2
               FROM  some table";
using (var command = new SqlCommand(sql, con))
{
    con.Open();
    using (var reader = command.ExecuteReader())
    {
        var list = new List<ClassName>();
        while (reader.Read())
            list.Add(new ClassName { Col1 = reader.GetString(0), Col2 = reader.GetInt32(1) });
        allRecords = list.ToArray();
    }
}

Note that i've presumed that the first column is a string and the second an integer. Just to demonstrate that C# is typesafe and how you use the DataReader.GetXY methods.

Well, we're using Amazon Web Services and so we are looking to use scripts and programs to get through this problem. So I have been on the hunt for a command line tool. So first I tried the trick of running

c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

but because I'm running a cloud based Windows Server 2012 it complained

This option is not supported on this version of the operating system. Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows Features On/Off" dialog, the Server Manager management tool, or the dism.exe command line tool. For more details please see http://go.microsoft.com/fwlink/?LinkID=216771.

and I Googled and found the official Microsoft Support Page KB2736284. So there is a command line tool dism.exe. So I tried the following

dism /online /enable-feature /featurename:IIS-ASPNET45

but it complained and gave a list of featurenames to try, so I tried them one by one and I tested my WebAPI webpage after each and it worked after the bottom one in the list.

dism /online /enable-feature /featurename:IIS-ApplicationDevelopment
dism /online /enable-feature /featurename:IIS-ISAPIFilter 
dism /online /enable-feature /featurename:IIS-ISAPIExtensions 
dism /online /enable-feature /featurename:IIS-NetFxExtensibility45 

And so now I can browse to my WebAPI site and see the API information. That should help a few people. [However, I am not out of the woods totally myself yet and I cannot reach the website from outside the box. Still working on it.]

Also, I did some earlier steps following other people responses. I can confirm that the following Feature Delegation needs to be change (though I'd like to find a command line tool for these).

In Feature delegation

Change 
'Handler Mappings' from Read Only to Read/Write

Change 
'Modules' from Read Only to Read/Write

Change 
'SSL Settings' from Read Only to Read/Write

using (var cmd = new SqlCommand("SELECT EmpName FROM [Employee] WHERE EmpID = @id", con))

put [] around table name ;)

The right answer is

Decoupled the build-specific components of the Android SDK from the platform-tools component, so that the build tools can be updated independently of the integrated development environment (IDE) components.

link (expand Revision 17)

First, check whether the table exists or not. Accordingly, create table if doesn't exist.

var commandStr= "If not exists (select name from sysobjects where name = 'Customer') CREATE TABLE Customer(First_Name char(50),Last_Name char(50),Address char(50),City char(50),Country char(25),Birth_Date datetime)";

using (SqlCommand command = new SqlCommand(commandStr, con))
command.ExecuteNonQuery();

I got this issue when deploying to Azure using the Publish feature. Remember to clear files at destination.

Publish Settings -> File Publish Options drop down -> Check Remove additional files at destination

This solved my issue, in case people have to hunt around for this like I did. Everything was the same version in my project/solution, just not at the destination I was deploying to.

I've seen some nice AngularJS charting solutions that make use of Highcharts. There's a highcharts-ng directive on GitHub to make AngularJS integration easier, and some examples on JSFiddle to give you a quick taste of what's possible.

You set up the chart on the JS side like this:

$scope.chart = {
    options: {
        chart: {
            type: 'bar'
        }
    },
    series: [{
        data: [10, 15, 12, 8, 7]
    }],
    title: {
        text: 'Hello'
    },
    loading: false
}

And then refer to it in the HTML like this:

<highchart id="chart1" config="chart"></highchart>

Usage/licensing warning: Highcharts is available for free under the Creative Commons license for non-commercial use. If you're looking for charting options in a for-profit/commercial scenario, you'll need to buy the product or look elsewhere.

You could also make the ajax call more generic, reusable, so you can call it from different CRUD(create, read, update, delete) tasks for example and treat the success cases from those calls.

makePostCall = function (url, data) { // here the data and url are not hardcoded anymore
   var json_data = JSON.stringify(data);

    return $.ajax({
        type: "POST",
        url: url,
        data: json_data,
        dataType: "json",
        contentType: "application/json;charset=utf-8"
    });
}

// and here a call example
makePostCall("index.php?action=READUSERS", {'city' : 'Tokio'})
    .success(function(data){
               // treat the READUSERS data returned
   })
    .fail(function(sender, message, details){
           alert("Sorry, something went wrong!");
  });

If you have two servers on the same domain (eg. APP and DB), you can also use Windows Authentication between the app and MSSQL by setting up local users on both machines that match (same username and password). If you don't have the passwords matched up, it can throw this error.

As a quick solution you can copy the JavaFX runtime JAR file and those referenced from Oracle JRE(JDK) or any self-contained application that uses JavaFX(e.g. JavaFX Scene Builder 2.0):

cp <JRE_WITH_JAVAFX_HOME>/lib/ext/jfxrt.jar     <JRE_HOME>/lib/ext/
cp <JRE_WITH_JAVAFX_HOME>/lib/javafx.properties <JRE_HOME>/lib/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libprism_*  <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libglass.so <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libjavafx_* <JRE_HOME>/lib/amd64/

just make sure you have the gtk 2.18 or higher

Try to use WebConfigurationManager instead of ConfigurationManager

Alternatively we can use eclipse update site (Help -> Install New Features -> Add Site (urls below) -> Select desired Features).

For Luna: http://download.eclipse.org/webtools/repository/luna

For Kepler: http://download.eclipse.org/webtools/repository/kepler

For Helios: http://download.eclipse.org/webtools/repository/helios

It's 2020 now, for the latest solution, you can use Burp Suite to sniffing https traffic without rooting your Android device.

Steps:

1. Install Burp Suite

2. Enable Proxy

3. Import the certification in your Android phone

4. Change you Wifi configuration to listening to proxy

5. Profit!

I wrote the full tutorial and screenshot on how to do it at here: https://www.yodiw.com/monitor-android-network-traffic-with-burp/

The general issue is just any issue involving Machine/Web/App configs.

I had the same connection strings in Machine.Config as in my App.Config so I put before my first connection string in my App.Config

You have to make sure your DLL is in the classpath.

One such way to do so is to put the path to the DLL in PATH environment variable.

Other option is to add it to the VM arguments in the variable LD_LIBRARY_PATH, like this:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

First, set customErrors = "Off" in the web.config and redeploy to get a more detailed error message that will help us diagnose the problem. You could also RDP into the instance and browse to the site from IIS locally to view the errors.

<system.web>
      <customErrors mode="Off" />

First guess though - you have some references (most likely Azure SDK references) that are not set to Copy Local = true. So, all your dependencies are not getting deployed.

Get to the detailed error first and update your question.

UPDATE: A second option now available in VS2013 is Remote Debugging a Cloud Service or Virtual Machine.

"Cannot attach the file 'C:\Github\TestService\TestService\App_data\TestService.mdf" as database 'TestService'

When you meet the above error message, Please do the following steps.

1. Open SQL Server Object Explorer
2. Click refresh button.
3. Expand (localdb)\MSSQLLocalDB(SQL Server 12.x.xxxxx - xxxxx\xxxx)
4. Expand Database
5. Please remove existed same name database
6. Click right button and then delete
7. Go back to your Package Manage Console
8. Update-Database

All you have to do is In your bLoanButton_Click , add a line to rebind the Grid to the SqlDataSource :

protected void bLoanButton_Click(object sender, EventArgs e)
{

//your same code
........

GridView1.DataBind();


}

If you want to display single value access from database into textbox, please refer to the code below:

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
TextBox1.Text=cmd.ExecuteScalar();
Con.Close();

or

SqlConnection con=new SqlConnection("connection string");
SqlCommand cmd=new SqlConnection(SqlQuery,Con);
Con.Open();
SqlDataReader dr=new SqlDataReadr();
dr=cmd.Executereader();
if(dr.read())
{
    TextBox1.Text=dr.GetValue(0).Tostring();
}
Con.Close();

If you want to do windows authentication, use the latest MS-JDBC driver and follow the instructions here:

https://msdn.microsoft.com/en-us/library/gg558122(v=sql.110).aspx

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

First Declare a variable to store filenames (to use them later):

var myfiles = [];

Open File Dialog

$('#browseBtn').click(function() {
    $('<input type="file" multiple>').on('change', function () {
        myfiles = this.files; //save selected files to the array
        console.log(myfiles); //show them on console
    }).click();
});

i'm posting it, so it may help someone because there are no clear instructions on the internet to how to store filenames into an array!

             if (reader.HasRows)
            {
                while (reader.Read())
                {
                    comboBox1.Items.Add(reader.GetString(0));
                }
            }
            reader.Close();

            MySqlDataReader reader1 = cmd1.ExecuteReader();
            if (reader1.HasRows)
            {
                while (reader1.Read())
                {
                    listBox1.Items.Add(reader1.GetString(0));
                }
            }
            reader1.Close();

Another cause is if the user's default database is unavailable.

I had an account that was used for backing up two databases. When the backup user's default database was taken off-line, the "no process on the other end of the pipe" error started.

I don't know if this still is an issue, but i prefere just to use the My.Settings in my code.

Visual Studio generates a simple class with functions for reading settings from the app.config file.

You can simply access it using My.Settings.ConnectionString.

    Using Context As New Data.Context.DataClasses()
        Context.Connection.ConnectionString = My.Settings.ConnectionString
    End Using

If you just need this for debugging to see how the XML looks like, then instead of print(xml.etree.ElementTree.tostring(e)) you can use dump like this:

xml.etree.ElementTree.dump(e)

And this works both with Element and ElementTree objects as e, so there should be no need for getroot.

The documentation of dump says:

xml.etree.ElementTree.dump(elem)

Writes an element tree or element structure to sys.stdout. This function should be used for debugging only.

The exact output format is implementation dependent. In this version, it’s written as an ordinary XML file.

elem is an element tree or an individual element.

Changed in version 3.8: The dump() function now preserves the attribute order specified by the user.

You dont need both jTDS and JDBC in your classpath. Any one is required. Here you need only sqljdbc.jar.

Also, I would suggest to place sqljdbc.jar at physical location to /WEB-INF/lib directory of your project rather than adding it in the Classpath via IDE. Then Tomcat takes care the rest. And also try restarting Tomcat.

You can download Jar from : www.java2s.com/Code/JarDownload/sqlserverjdbc/sqlserverjdbc.jar.zip

EDIT:

As you are supplying Username and Password when connecting,

You need only jdbc:sqlserver://localhost:1433;databaseName=test, Skip integratedSecurity attribute.

Each individual Web App under an IIS Web Site can use a different App Pool.

Verify the App Pool assigned to your app (not just the root site per your pictures) is .NET 4.0 compatible:

1. Expand Default Web Site
2. Right click on ProjectPALS, choose 'Manage Application' then 'Advanced...'
3. Observe the 'Application Pool' your app is running as under the site
4. Change to another App Pool if neccessary

Ages old post, but still good enough. I think hiding it in an .so library would be great, using NDK and C++ of course. .so files can be viewed in a hex editor, but good luck decompiling that :P

 public Person SomeMethod(string fName)
        {
            var con = ConfigurationManager.ConnectionStrings["Yourconnection"].ToString();

            Person matchingPerson = new Person();
            using (SqlConnection myConnection = new SqlConnection(con))
            {
                string oString = "Select * from Employees where FirstName=@fName";
                SqlCommand oCmd = new SqlCommand(oString, myConnection);
                oCmd.Parameters.AddWithValue("@Fname", fName);           
                myConnection.Open();
                using (SqlDataReader oReader = oCmd.ExecuteReader())
                {
                    while (oReader.Read())
                    {    
                        matchingPerson.firstName = oReader["FirstName"].ToString();
                        matchingPerson.lastName = oReader["LastName"].ToString();                       
                    }

                    myConnection.Close();
                }               
            }
            return matchingPerson;
        }

Few things to note here: I used a parametrized query, which makes your code safer. The way you are making the select statement with the "where x = "+ Textbox.Text +"" part opens you up to SQL injection.

I've changed this to:

  "Select * from Employees where FirstName=@fName"
  oCmd.Parameters.AddWithValue("@fname", fName);  

So what this block of code is going to do is:

Execute an SQL statement against your database, to see if any there are any firstnames matching the one you provided. If that is the case, that person will be stored in a Person object (see below in my answer for the class). If there is no match, the properties of the Person object will be null.

Obviously I don't exactly know what you are trying to do, so there's a few things to pay attention to: When there are more then 1 persons with a matching name, only the last one will be saved and returned to you. If you want to be able to store this data, you can add them to a List<Person> .

Person class to make it cleaner:

 public class Person
    {
            public string firstName { get; set; }
            public string lastName { get; set; }
    }

Now to call the method:

Person x = SomeMethod("John");

You can then fill your textboxes with values coming from the Person object like so:

txtLastName.Text = x.LastName;

I was having session file not found error while tried various ways, finally achieved like this. Made the function as static (which I want to call in the another controller), and called like

Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.

There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.

There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are

• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2012 (SSIS packages target SQL Server 2012)
• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2013 (SSIS packages target SQL Server 2014)

None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals

The answer is .IsPostBack as suggested by @Kundan Singh Chouhan. Just to add to it, move your code into a separate method from Page_Load

private void PopulateFields()
{
  using(SqlConnection con1 = new SqlConnection("Data Source=USER-PC;Initial Catalog=webservice_database;Integrated Security=True"))
  {
    DataTable dt = new DataTable();
    con1.Open();
    SqlDataReader myReader = null;  
    SqlCommand myCommand = new SqlCommand("select * from customer_registration where username='" + Session["username"] + "'", con1);

    myReader = myCommand.ExecuteReader();

    while (myReader.Read())
    {
        TextBoxPassword.Text = (myReader["password"].ToString());
        TextBoxRPassword.Text = (myReader["retypepassword"].ToString());
        DropDownListGender.SelectedItem.Text = (myReader["gender"].ToString());
        DropDownListMonth.Text = (myReader["birth"].ToString());
        DropDownListYear.Text = (myReader["birth"].ToString());
        TextBoxAddress.Text = (myReader["address"].ToString());
        TextBoxCity.Text = (myReader["city"].ToString());
        DropDownListCountry.SelectedItem.Text = (myReader["country"].ToString());
        TextBoxPostcode.Text = (myReader["postcode"].ToString());
        TextBoxEmail.Text = (myReader["email"].ToString());
        TextBoxCarno.Text = (myReader["carno"].ToString());
    }
    con1.Close();
  }//end using
}

Then call it in your Page_Load

protected void Page_Load(object sender, EventArgs e)
{

    if(!Page.IsPostBack)
    {
       PopulateFields();
    }
}

If you are connecting from Windows machine A to Windows machine B (server with SQL Server installed), and are getting this error, you need to do the following:

On machine B:

1.) turn on the Windows service called "SQL Server Browser" and start the service

2.) in the Windows firewall, enable incoming port UDP 1434 (in case SQL Server Management Studio on machine A is connecting or a program on machine A is connecting)

3.) in the Windows firewall, enable incoming port TCP 1433 (in case there is a telnet connection)

4.) in SQL Server Configuration Manager, enable TCP/IP protocol for port 1433

While running Visual Studio 2012 behind a proxy, I received the following error message when checking for extension updates in the Visual Studio Gallery:

The remote server returned an unexpected response: (417) Expectation failed

A look around Google finally revealed a solution here:

Visual Studio 2012 Proxy Settings

http://www.jlpaonline.com/?p=176

Basically, he's saying the fix is to edit your devenv.exe.config file and change this:

<settings>      
   <ipv6 enabled="true"/> 
</settings>

to this:

 <settings>
   <ipv6 enabled="true"/>      
   <servicePointManager expect100Continue="false"/> 
 </settings> 

The following should work. Keep single connection open all time, and just create new commands and execute them.

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (SqlCommand command1 = new SqlCommand(commandText1, connection))
    {
    }
    using (SqlCommand command2 = new SqlCommand(commandText2, connection))
    {
    }
    // etc
}

Following Code will work for "Inserting values into a SQL Server database using ado.net via C#"

// Your Connection string
string connectionString = "Data Source=DELL-PC;initial catalog=AdventureWorks2008R2 ; User ID=sa;Password=sqlpass;Integrated Security=SSPI;";

// Collecting Values
string firstName="Name",
    lastName="LastName",
    userName="UserName",
    password="123",
    gender="Male",
    contact="Contact";
int age=26; 

// Query to be executed
string query = "Insert Into dbo.regist (FirstName, Lastname, Username, Password, Age, Gender,Contact) " + 
                   "VALUES (@FN, @LN, @UN, @Pass, @Age, @Gender, @Contact) ";

    // instance connection and command
    using(SqlConnection cn = new SqlConnection(connectionString))
    using(SqlCommand cmd = new SqlCommand(query, cn))
    {
        // add parameters and their values
        cmd.Parameters.Add("@FN", System.Data.SqlDbType.NVarChar, 100).Value = firstName;
        cmd.Parameters.Add("@LN", System.Data.SqlDbType.NVarChar, 100).Value = lastName;
        cmd.Parameters.Add("@UN", System.Data.SqlDbType.NVarChar, 100).Value = userName;
        cmd.Parameters.Add("@Pass", System.Data.SqlDbType.NVarChar, 100).Value = password;
        cmd.Parameters.Add("@Age", System.Data.SqlDbType.Int).Value = age;
        cmd.Parameters.Add("@Gender", System.Data.SqlDbType.NVarChar, 100).Value = gender;
        cmd.Parameters.Add("@Contact", System.Data.SqlDbType.NVarChar, 100).Value = contact;

        // open connection, execute command and close connection
        cn.Open();
        cmd.ExecuteNonQuery();
        cn.Close();
    }    

I also ran into that problem. My MVC4 App is running on a Windows Server 2012 R2 with IIS 8.5. None of these posted solutions worked for me...installing the missing frameworks through IIS Features could have solved it but the installation always failed.

I had to use the Web Platform Installer and installed the following packages:

IntelliJ IDEA 2018.3.6

Using macOS Mojave Version 10.14.4 and pressing ?F12(Alt+F12) will open Sound preferences.

A solution without changing the current keymap is to use the command above with the key fn.

fn ? F12(fn+Alt+F12) will open the Terminal. And you can use ShiftEsc to close it.

Update-Package -reinstall Microsoft.Web.Infrastructure didn't work for me, as I kept receiving errors that it was already installed.

I had to navigate to the Microsoft.Web.Infrastructure.1.0.0.0 folder in the packages folder and manually delete that folder.

After doing this, running Install-Package Microsoft.Web.Infrastructure installed it.

Note: CopyLocal was automatically set to true.

Use (localdb)\MSSQLLocalDBwith Windows Auth

You probably just need to provide a user name and password in your connectionstring and set Integrated Security=false

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

This works for me:

C:\Users\example>keytool -exportcert -alias androiddebugkey -keystore 
"C:\Users\example\.android" | "C:\openssl\bin\openssl.exe" sha1 -binary 
| "C:\openssl\bin\oenssl.exe" base64

The solution to this problem is as simple as eating a piece of cake.This issue generally arises when your user credentials change and SQL server is not able to identify you .No need to uninstall the existing SQL server instance .You can simply install a new instance with a new instance name . Lets say if your last instance name was 'Sqlexpress' , so this time during installation , name your instance as 'Sqlexpress1' . Also don't forget to select the mix mode (i.e Sql Server Authentication & Windows Authentication) during the installation and provide a system admin password which will be handy if such a problem occurs in future. This solution will definitely resolve this issue. Thanks..

I had the same issue, but none of the above worked for me. They did put me in to the right direction though.

For example when I set the "Copy Local" to "true" for System.Web.Mvc reference, it automatically sets it back to False.

I have multiple projects which depend on the System.Web.Mvc reference in my solution, but only one caused this problem. In VS 2012 this reference is labeled with the yellow attention triangle.

Find this reference => remove it => re-add it

That fixed it for me. Hope this helps

The following example Web.config file will configure IIS to deny access for HTTP requests where the length of the "Content-type" header is greater than 100 bytes.

  <configuration>
   <system.webServer>
      <security>
         <requestFiltering>
            <requestLimits>
               <headerLimits>
                  <add header="Content-type" sizeLimit="100" />
               </headerLimits>
            </requestLimits>
         </requestFiltering>
      </security>
   </system.webServer>

This is a fairly old thread, but since I was reinstalling my Visual Studio 2015 Community today, I thought I might add some info on what to use on VS2015, or what might work in general.

To see which instances were installed by default, type sqllocaldb info inside a command prompt. On my machine, I get two instances, the first one named MSSQLLocalDB.

C:\>sqllocaldb info
MSSQLLocalDB
ProjectsV13

You can also create a new instance if you wish, using sqllocaldb create "some_instance_name", but the default one will work just fine:

// if not using a verbatim string literal, don't forget to escape backslashes
@"Server=(localdb)\MSSQLLocalDB;Integrated Security=true;"

A proposed solution will be:

Actually this error occurs when server makes connection but can't build due to failure in identifying connection function identifier. This problem can be solved by typing connection function in code. For this I take a simple example. In this case function is con your may be different.

SqlCommand cmd = new SqlCommand("insert into ptb(pword,rpword) values(@a,@b)",con);

Keyboard shortcut to toggle the docking position (side/bottom)

CTRL+SHIFT+D

And there are many shortcuts you can see them by going to

Settings » Shortcuts, as displayed here:

Alternatively, use CTRL + ? to go to the settings, from there one can reach the "Shortcuts" sub-item on the left or use the Official reference.

Shortest version without form, min or external JavaScript.

<input type="range" value="0" max="10" oninput="num.value = this.value">
<output id="num">0</output>

Explanation

If you wanna retrieve the value from the output you commonly use an id that can be linked from the oninput instead of using this.nextElementSibling.value (we take advantage of something that we are already using)

Compare the example above with this valid but a little more complex and long answer:

<input id="num" type="range" value="0" max="100" oninput="this.nextElementSibling.value = this.value">
<output>0</output>

With the shortest answer:

• We avoid the use of this, something weird in JS for newcomers
• We avoid new concept about connecting siblings in the DOM
• We avoid too much attributes in the input placing the id in the output

Notes

• In both examples we don't need to add the min value when equal to 0
• Removing JavaScript’s this keyword makes it a better language

If none of the above solutions solved your issue like in my case (still stuck with my RestClient module facing 405 ) try to request your Api with a tool like Postman or Fiddler. I mean the problem may be elsewhere like a bad formatted request.

I discover that my RestClient module was asking a 'Put' with an Id paremeter not well formatted :

http://myserver/api/someresource?id=75fd954d-d984-4a31-82fc-8132e1644f78

instead of

http://myserver/api/someresource/75fd954d-d984-4a31-82fc-8132e1644f78

Incidiously, bad formatted request returns 405 - Method Not Allowed (IIS 7.5)

This piece of configuration in web.config file can help as helped to me: in the system.webServer section:

      <security>
          <requestFiltering>
              <verbs applyToWebDAV="true">
                  <remove verb="PUT" />
                  <add verb="PUT" allowed="true" />
                  <remove verb="DELETE" />
                  <add verb="DELETE" allowed="true" />
                  <remove verb="PATCH" />
                  <add verb="PATCH" allowed="true" />
              </verbs>
          </requestFiltering>
      </security>      

Which would you rather write and maintain?

ASP.NET MVC

public class TweetsController : Controller {
  // GET: /Tweets/
  [HttpGet]
  public ActionResult Index() {
    return Json(Twitter.GetTweets(), JsonRequestBehavior.AllowGet);
  }
}

ASP.NET Web API

public class TweetsController : ApiController {
  // GET: /Api/Tweets/
  public List<Tweet> Get() {
    return Twitter.GetTweets();
  }
}

You haven't declared returnImage as any kind of variable :)

This should help:

public Image byteArrayToImage(byte[] byteArrayIn)
{
    try
    {
        MemoryStream ms = new MemoryStream(byteArrayIn,0,byteArrayIn.Length);
        ms.Write(byteArrayIn, 0, byteArrayIn.Length);
        Image returnImage = Image.FromStream(ms,true);
    }
    catch { }
    return returnImage;
}

if you want to change only a column.for example from string to int32 you can use Expression property:

DataColumn col = new DataColumn("col_int" , typeof(int));
table.Columns.Add(col);
col.Expression = "table_exist_col_string"; // digit string convert to int  

Add space between Data Source

 con.ConnectionString = @"Data Source=.\SQLEXPRESS;
                          AttachDbFilename=c:\folder\SampleDatabase.mdf;
                          Integrated Security=True;
                          Connect Timeout=30;
                          User Instance=True";

Also you need to check if individual record is not getting updated in the logic because with update trigger in the place causes time out error too.

So, the solution is to make sure you perform bulk update after the loop/cursor instead of one record at a time in the loop.

In my case, I've had to click on my project, then go to File > Properties > *servlet name* and click Restart servlet.

I've been using something like this. Just set up a simple HTML page with an textinput. Make sure that the textinput always has focus. When you scan a barcode with your barcode scanner you will receive the code and after that a 'enter'. Realy simple then; just capture the incoming keystrokes and when the 'enter' comes in you can use AJAX to handle your code.

Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.

As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.

Taken from this answer.

1. Close your packages.config file.
2. Build
3. Warning is gone!

This is the first time I see ignoring a problem actually makes it go away...

Edit in 2020: if you are viewing this warning, consider upgrading to PackageReference if you can

Remove element should clear out such errors. The reason behind this is the inherited settings. Your application will inherit some settings from its parent's config file and machine's (server) config files.
You can either remove such duplicates with the remove tag before adding them or make these tags non-inheritable in the upper level config files.

you can use

reader.GetInt32(3);

to read an 32 bit int from the data reader.

If you know the type of your data I think its better to read using the Get* methods which are strongly typed rather than just reading an object and casting.

Have you considered using

reader.GetInt32(reader.GetOrdinal(columnName)) 

rather than accessing by position. This makes your code less brittle and will not break if you change the query to add new columns before the existing ones. If you are going to do this in a loop, cache the ordinal first.

In your web.config, make sure these keys exist:

<configuration>
    <system.webServer>
        <validation validateIntegratedModeConfiguration="false"/>
    </system.webServer>
</configuration>

Believe it or not, renaming LinqPad.exe.config to LinqPad.config solved this problem.

Error: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

I found the articles to fix this issue by simply run the following commands at the command prompt:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If the system is 32 bit, it would have looked like this:

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i

But, when I tried to execute these commands using a command prompt, I got the following error/warning message:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -i Microsoft (R) ASP.NET RegIIS version 4.0.30319.33440 Administration utility to install and uninstall ASP.NET on the local machine.

Administr ators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Win dows Features On/Off" dialog, the Server Manager management tool, or the dism.exe command line tool. For more details please see http://go.microsoft.com/fwlin k/?LinkID=216771. Finished installing ASP.NET (4.0.30319.33440).**

To fix this on a Windows 8.1, I would suggest to do the following thing.

Solution:

Goto: Turn Windows features on or off -> Internet Information Services -> World Wide Web Services -> Application Development Features -> Enable ASP.NET 4.5

This should resolve the issue.

First, you need to obtain the public certificate from the server you're trying to connect to. That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. (Google should be able to tell you exactly what to do for your specific browser.)

Now that you have the certificate saved in a file, you need to add it to your JVM's trust store. At $JAVA_HOME/jre/lib/security/ for JREs or $JAVA_HOME/lib/security for JDKs, there's a file named cacerts, which comes with Java and contains the public certificates of the well-known Certifying Authorities. To import the new cert, run keytool as a user who has permission to write to cacerts:

keytool -import -file <the cert file> -alias <some meaningful name> -keystore <path to cacerts file>

It will most likely ask you for a password. The default password as shipped with Java is changeit. Almost nobody changes it. After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key).

1) Create a new form and add this:

Imports System.Configuration
Imports Operaciones.My.MySettings

Public NotInheritable Class frmconexion

    Private Shared _cnx As String
    Public Shared Property ConexionMySQL() As String
        Get
            Return My.MySettings.Default.conexionbd
        End Get
        Private Set(ByVal value As String)
            _cnx = value
        End Set
    End Property

End Class

then when you want to use the connection do this in ur form:

 Private Sub frmInsert_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim cn As New MySqlConnection(frmconexion.ConexionMySQL)
cn.open()

and thats it. You will be connected to the DB and can do stuff.

This is for vb.net but the logic is the same.

I tried most of the answers and unfortunately, none of them worked in completion.

Here is what worked for me. There are 3 things to do to the site you want PUT for (select the site) :

1. Open WebDav Authoring Rules and then select Disable WebDAV option present on the right bar.

2. Select Modules, find the WebDAV Module and remove it.

3. Select HandlerMapping, find the WebDAVHandler and remove it.

Restart IIS.

As mentioned you should assign the connection and you should preferably also use sql parameters instead, so your command assignment would read:

    // 3. Pass the connection to a command object
    SqlCommand cmd=new SqlCommand ("insert into time(project,iteration) values (@project, @iteration)", conn); // ", conn)" added
    cmd.Parameters.Add("project", System.Data.SqlDbType.NVarChar).Value = this.name1.SelectedValue;
    cmd.Parameters.Add("iteration", System.Data.SqlDbType.NVarChar).Value = this.name1.SelectedValue;

    //
    // 4. Use the connection
    //

By using parameters you avoid SQL injection and other problematic typos (project names like "myproject's" is an example).

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

https://msdn.microsoft.com/en-us/library/dd465326(VS.100).aspx

Here is my preferred quickest and easiest solution. Works well if all slides have the same background color that you want to remove.

Step 1. In Powerpoint, "Save As" (shortcut F12) PNG, "All Slides".

Now you have a folder full of these PNG images of all your slides. The problem is that they still have a background. So now:

Step 2. Batch remove background color of all the PNG images, for example by following the steps in this SE answer.

I needed to add permissions to IUSR (in addition to ISS-IUSRS, as others have suggested). (See also: http://codeasp.net/blogs/raghav_khunger/microsoft-net/2099/iis-7-5-windows-7-http-error-401-3-unauthorized)

Don't create mistakes on your server by changing everything. If you have windows prompt to logon when using Windows Authentication on 2008 R2, just go to Providers and move UP NTLM for each your application. When Negotiate is first one in the list, Windows Authentication can stop to work property for specific application on 2008 R2 and you can be prompted to enter username and password than never work. That sometime happens when you made an update of your application. Just be sure than NTLM is first on the list and you will never see this problem again.

I was having this problem on a Windows 7 (64 bit) after a power outage. The SQLEXPRESS service was not started even though is status was set to 'Automatic' and the mahine had been rebooted several times. Had to start the service manually.

If you just need the core.jar from zxing, you can skip that process and get the pre-built JARs from the GettingStarted wiki page

Latest ZXing (2.2) doesn't have core.jar under core folder but you can obtain the core.jar from the zxing Maven repository here

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

Check if there is any conflict in your IIS authentication. i.e. you enable the anonymous authentication and ASP.NET impersonation both might cause the error also.

I think you should add style="background:white;" to make looks like it is writable

<input type="text" size="23" name="dateMonthly" id="dateMonthly" readonly="readonly"   style="background:white;"/>

In Netbeans, we can use Tools->Options-> General Tab - > Under proxy settings, select Use system proxy settings.

This way, it uses the proxy settings provided in Settings -> Control Panel -> Internet Options -> Connections -> Lan Settings -> use automatic configuration scripts.

If you are using maven, make sure the proxy settings are not provided there, so that it uses Netbeans settings provided above for proxy.

Hope this helps.

I am reading the Pro ASP.NET MVC 4 book as well, and ran into the same problem you were having. For me, I started having the problem after making the changes prescribed in the 'Adding Model Validation' section of the book. The way I resolved the problem is by moving my database from the localdb to the full-blown SQL Server 2012 server. (BTW, I know that I am lucky I could switch to the full-blown version, so don't hate me. ;-))) There must be something with the communication to the db that is causing the problem.

Check out the connection strings web site which has tons of example for your connection strings.

Basically, you need three things:

• name of the server you want to connect to (use "." or (local) or localhost for the local machine)
• name of the database you want to connect to
• some way of defining the security - either integrated Windows security, or define a user name / password combo

For example, if you want to connect to your local machine and the AdventureWorks database using integrated security, use:

server=(local);database=AdventureWorks;integrated security=SSPI;

Or if you have SQL Server Express on your machine in the default installation, and you want to connect to the AdventureWorksLT2008 database, use this:

server=.\SQLExpress;database=AdventureWorksLT2008;integrated Security=SSPI;

You can shorten JSprangs solution a bit by using a method group instead:

string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ints = s1.Split(';').Select(int.Parse).ToArray();

I haven't used it, but RazorSQL looks pretty good.

In my case, the error was caused by incorrect mapping settings in the file applicationhost.config (\System32\inetsrv\config). For some reason, Visual Studio 2013 corrupted it while creating a virtual directory in IIS. The fix was to manually edit the sites section in the file.

If you use the Geolocation API, it would be as simple as using the following code.

navigator.geolocation.getCurrentPosition(function(location) {
  console.log(location.coords.latitude);
  console.log(location.coords.longitude);
  console.log(location.coords.accuracy);
});

You may also be able to use Google's Client Location API.

This issue has been discussed in Is it possible to detect a mobile browser's GPS location? and Get position data from mobile browser. You can find more information there.

If you haven't created the database in your server you will get the same login error.Make sure that the database exist before you login.

In visual studio 2012, When I published the solution mistakenly with 'debug' option I got this exception. With 'release' option it never occurred. Hope it helps.

I found the problem was that I had the server path within the connection string in one of these variants:

SERVER\SQLEXPRESS
SERVER

When really I should have:

.\SQLEXPRESS

For some reason I got the error whenever it had difficulty locating the instance of SQL.

I had another problem that led to this issue.

• I had ensured my app pool was running .net 4 in integrated mode
• I had run aspnet_regiis.exe -i
• I had checked folder permissions were set correctly for the account running my app pool

None of these things worked. It turned out that in my web.config under system.webserver > modules I had the following:

<remove name="WindowsAuthentication" />

Obviously this removed the windows authentication module which seemed to somehow knock everything off kilter.

I hope this helps someone, as this cost me most of an evening!

I had the same problem on Windows 7 and tried everything: cleaned DLLs, investigated modules' list, turned off "Just My Code", and so on.

The problem was solved after I've run Visual Studio "as administrator". Honestly. Why Microsoft couldn't just warn me that it's not running "as administrator"? It would save me some hours of work.

I had the same problem. Don't remember where I found it on the web, but here is what I did:

Click "Start button"

in the search box, enter "Turn windows features on or off"

in the features window, Click: "Internet Information Services"

Click: "World Wide Web Services"

Click: "Application Development Features"

Check (enable) the features. I checked all but CGI.

IIS - this configuration section cannot be used at this path (configuration locking?)

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

In my case the problem was that I started to create an MVC Alloy sample project from scratch in using Visual Studio/Episerver extension and it worked fine when executed using local Visual studio iis express. However by default it points the sql database to LocalDB and when I deployed the site to local IIS it started giving errors some of the initial errors I resolved by: 1.adding the local site url binding to C:/Windows/System32/drivers/etc/hosts 2. Then by editing the application.config found the file location by right clicking on IIS express in botton right corner of the screen when running site using Visual studio and added binding there for local iis url. 3. Finally I was stuck with "unable to access database errors" for which I created a blank new DB in Sql express and changed connection string in web config to point to my new DB and then in package manager console (using Visual Studio) executed Episerver DB commands like - 1. initialize-epidatabase 2. update-epidatabase 3. Convert-EPiDatabaseToUtc

My IIS 7.5 does not understand tag in web.config In VS 2010 it is underline that tag also. Check your config file accurate to find all underlined tags. I put it in the comment and error goes away.

This worked for me:

PowerShell.exe -Command "& ""C:\Some Script\Path With Spaces.ps1"""

The key seems to be that the whole command is enclosed in outer quotes, the "&" ampersand is used to specify another child command file is being executed, then finally escaped (doubled-double-) quotes around the path/file name with spaces in you wanted to execute in the first place.

This is also completion of the only workaround to the MS connect issue that -File does not pass-back non-zero return codes and -Command is the only alternative. But until now it was thought a limitation of -Command was that it didn't support spaces. I've updated that feedback item too.

I had this problem when I started using Entity Framework, it happened when I did not change the old SQL server connection to EntityFrameWork connection.

Solution: in the file where connection is made through web.config file "add name="Entities" connectionString=XYZ", make sure you are referring to the correct connection, in my case I had to do this

        public static string MyEntityFrameworkConnection
    {
        get
        {
             return ConfigurationManager.ConnectionStrings["Entities"].ConnectionString;
        }

    }

call MyEntityFrameworkConnection whenever connection need to be established.

private string strConnection= Library.DataAccessLayer.DBfile.AdoSomething.MyEntityFrameworkConnection;

note: the connection in web.config file will be generated automatically when adding Entity model to the solution.

Please, note that Open and Close the connection is not necessary when using DataAdapter.

So I suggest please update this code and remove the open and close of the connection:

        SqlDataAdapter adapt = new SqlDataAdapter(cmd);

conn.Open(); // this line of code is uncessessary

        Console.WriteLine("connection opened successfuly");
        adapt.Fill(table);

conn.Close(); // this line of code is uncessessary

        Console.WriteLine("connection closed successfuly");

Reference Documentation

The code shown in this example does not explicitly open and close the Connection. The Fill method implicitly opens the Connection that the DataAdapter is using if it finds that the connection is not already open. If Fill opened the connection, it also closes the connection when Fill is finished. This can simplify your code when you deal with a single operation such as a Fill or an Update. However, if you are performing multiple operations that require an open connection, you can improve the performance of your application by explicitly calling the Open method of the Connection, performing the operations against the data source, and then calling the Close method of the Connection. You should try to keep connections to the data source open as briefly as possible to free resources for use by other client applications.

You mean that your code is DDL? If so, MSSQL has no difference. Above examples well shows how to invoke this. Just ensure

CommandType = CommandType.Text

Integrated Security = False : User ID and Password are specified in the connection. Integrated Security = true : the current Windows account credentials are used for authentication.

Integrated Security = SSPI : this is equivalant to true.

We can avoid the username and password attributes from the connection string and use the Integrated Security

There are several possible catches. I think that the most common error is in this part of the connection string:

res://xxx/yyy.csdl|res://xxx/yyy.ssdl|res://xxx/yyy.msl;

This is no magic. Once you understand what is stands for you'll get the connection string right.

First the xxx part. That's nothing else than an assembly name where you defined you EF context clas. Usually it would be something like MyProject.Data. Default value is * which stands for all loaded assemblies. It's always better to specify a particular assembly name.

Now the yyy part. That's a resource name in the xxx assembly. It will usually be something like a relative path to your .edmx file with dots instead of slashes. E.g. Models/Catalog - Models.Catalog The easiest way to get the correct string for your application is to build the xxx assembly. Then open the assembly dll file in a text editor (I prefer the Total Commander's default viewer) and search for ".csdl". Usually there won't be more than 1 occurence of that string.

Your final EF connection string may look like this:

res://MyProject.Data/Models.Catalog.DataContext.csdl|res://MyProject.Data/Models.Catalog.DataContext.ssdl|res://MyProject.Data/Models.Catalog.DataContext.msl;

A). I never have and never will trust any tool which purports to produce code without the user coding, which goes double where it's a graphical tool.

B). I've never had any problem with this with Facebook Connect. It's all still plain old JavaScript code running in a browser and undefined===undefined wherever you are.

In short, you need to provide evidence that your object.x really really was undefined and not null or otherwise, because I believe it is impossible for what you're describing to actually be the case - no offence :) - I'd put money on the problem existing in the Tersus code.

IIS 6.0 and previous versions :

ASP.NET integrated with IIS via an ISAPI extension, a C API ( C Programming language based API ) and exposed its own application and request processing model.

This effectively exposed two separate server( request / response ) pipelines, one for native ISAPI filters and extension components, and another for managed application components. ASP.NET components would execute entirely inside the ASP.NET ISAPI extension bubble AND ONLY for requests mapped to ASP.NET in the IIS script map configuration.

Requests to non ASP.NET content types:- images, text files, HTML pages, and script-less ASP pages, were processed by IIS or other ISAPI extensions and were NOT visible to ASP.NET.

The major limitation of this model was that services provided by ASP.NET modules and custom ASP.NET application code were NOT available to non ASP.NET requests

What's a SCRIPT MAP ?

Script maps are used to associate file extensions with the ISAPI handler that executes when that file type is requested. The script map also has an optional setting that verifies that the physical file associated with the request exists before allowing the request to be processed

A good example can be seen here

IIS 7 and above

IIS 7.0 and above have been re-engineered from the ground up to provide a brand new C++ API based ISAPI.

IIS 7.0 and above integrates the ASP.NET runtime with the core functionality of the Web Server, providing a unified(single) request processing pipeline that is exposed to both native and managed components known as modules ( IHttpModules )

What this means is that IIS 7 processes requests that arrive for any content type, with both NON ASP.NET Modules / native IIS modules and ASP.NET modules providing request processing in all stages This is the reason why NON ASP.NET content types (.html, static files ) can be handled by .NET modules.

• You can build new managed modules (IHttpModule) that have the ability to execute for all application content, and provided an enhanced set of request processing services to your application.
• Add new managed Handlers ( IHttpHandler)

For anyone still having this problem: based on this article

I found out that my server was missing the Microsoft C++ Visual Runtime Library - I had it on my dev machine because of the Visual Studio installed. I downloaded and installed the (currently) most recent version of the library from here:

http://www.microsoft.com/en-us/download/details.aspx?id=13523

Ran the setup and the oracle call from C# made it!

If you want the whole record,here is a lambda way:

var q = _context
             .lasttraces
             .GroupBy(s => s.AccountId)
             .Select(s => s.OrderByDescending(x => x.Date).FirstOrDefault());

I will say no.

But the only proof that I have is personal experience and the fact that documentation on line continuation doesn't have anything else in it.

http://msdn.microsoft.com/en-us/library/aa711641(VS.71).aspx

There's another thread elsewhere on Stack with a similar topic and the best solution I've come across is to use the free version of Helicon Ape

Once you've got that installed, follow the steps at the page Titled "HTTP Authentication and Authorization"

If you're deploying on Windows, the Windows Script Host offers a very useful JScript API to the file system and other local resources. Incorporating WSH scripts into a local web application may not be as elegant as you might wish, however.

Edit 7/17/2020: I cannot delete this accepted answer. It used to be good, but now it isn't. Beware really old posts, guys. I'm removing the link.

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

Code coverage features, as well as programmable API's, come with Visual Studio 2010. Sadly, the only two editions that include the full Code Coverage capabilities are Premium and Ultimate. However, I do believe the API's will be available with any edition, so creating code coverage files and writing a viewer for the coverage info would likely be possible.

I know this is an old thread, but I thought I'd post a vote for xUnit.NET. While most of the other testing frameworks mentioned are all pretty much the same, xUnit.NET has taken a pretty unique, modern, and flexible approach to unit testing. It changes terminology, so you no longer define TestFixtures and Tests...you specify Facts and Theories about your code, which integrates better with the concept of what a test is from a TDD/BDD perspective.

xUnit.NET is also EXTREMELY extensible. Its FactAttribute and TraitAttribute attribute classes are not sealed, and provide overridable base methods that give you a lot of control over how the methods those attributes decorate should be executed. While xUnit.NET in its default form allows you to write test classes that are similar to NUnit test fixtures with their test methods, you are not confined to this form of unit testing at all. You are free to extend the framework to support BDD-style Concern/Context/Observation specifications, as depicted here.

xUnit.NET also supports fit-style testing directly out of the box with its Theory attribute and corresponding data attributes. Fit input data may be loaded from excel, database, or even a custom data source such as a Word document (by extending the base data attribute.) This allows you to capitalize on a single testing platform for both unit tests and integration tests, which can be huge in reducing product dependencies and required training.

Other approaches to testing may also be implemented with xUnit.NET...the possibilities are pretty limitless. Combined with another very forward looking mocking framework, Moq, the two create a very flexible, extensible, and powerful platform for implementing automated testing.

After lots of research, I've come up with this answer, and I'm hereby putting it here as an answer for my own question, for reference:

1. Make sure that "Enable access for assistive devices" is checked in System Preferences>>Universal Access. It is required for the AppleScript to work. You may have to reboot after this change (it doesn't work otherwise on Mac OS X Server 10.4).

2. Create a R/W DMG. It must be larger than the result will be. In this example, the bash variable "size" contains the size in Kb and the contents of the folder in the "source" bash variable will be copied into the DMG:

   hdiutil create -srcfolder "${source}" -volname "${title}" -fs HFS+ \
         -fsargs "-c c=64,a=16,e=16" -format UDRW -size ${size}k pack.temp.dmg
   

3. Mount the disk image, and store the device name (you might want to use sleep for a few seconds after this operation):

   device=$(hdiutil attach -readwrite -noverify -noautoopen "pack.temp.dmg" | \
            egrep '^/dev/' | sed 1q | awk '{print $1}')
   

4. Store the background picture (in PNG format) in a folder called ".background" in the DMG, and store its name in the "backgroundPictureName" variable.

5. Use AppleScript to set the visual styles (name of .app must be in bash variable "applicationName", use variables for the other properties as needed):

   echo '
      tell application "Finder"
        tell disk "'${title}'"
              open
              set current view of container window to icon view
              set toolbar visible of container window to false
              set statusbar visible of container window to false
              set the bounds of container window to {400, 100, 885, 430}
              set theViewOptions to the icon view options of container window
              set arrangement of theViewOptions to not arranged
              set icon size of theViewOptions to 72
              set background picture of theViewOptions to file ".background:'${backgroundPictureName}'"
              make new alias file at container window to POSIX file "/Applications" with properties {name:"Applications"}
              set position of item "'${applicationName}'" of container window to {100, 100}
              set position of item "Applications" of container window to {375, 100}
              update without registering applications
              delay 5
              close
        end tell
      end tell
   ' | osascript
   

6. Finialize the DMG by setting permissions properly, compressing and releasing it:

   chmod -Rf go-w /Volumes/"${title}"
   sync
   sync
   hdiutil detach ${device}
   hdiutil convert "/pack.temp.dmg" -format UDZO -imagekey zlib-level=9 -o "${finalDMGName}"
   rm -f /pack.temp.dmg 
   

On Snow Leopard, the above applescript will not set the icon position correctly - it seems to be a Snow Leopard bug. One workaround is to simply call close/open after setting the icons, i.e.:

..
set position of item "'${applicationName}'" of container window to {100, 100}
set position of item "Applications" of container window to {375, 100}
close
open

At least for Qt specific projects, the Qt Creator (from Nokia/Trolltech/Digia) shows great promise.

Calling a polymorphic function from a constructor is a recipe for disaster in most OO languages. Different languages will perform differently when this situation is encountered.

The basic problem is that in all languages the Base type(s) must be constructed previous to the Derived type. Now, the problem is what does it mean to call a polymorphic method from the constructor. What do you expect it to behave like? There are two approaches: call the method at the Base level (C++ style) or call the polymorphic method on an unconstructed object at the bottom of the hierarchy (Java way).

In C++ the Base class will build its version of the virtual method table prior to entering its own construction. At this point a call to the virtual method will end up calling the Base version of the method or producing a pure virtual method called in case it has no implementation at that level of the hierarchy. After the Base has been fully constructed, the compiler will start building the Derived class, and it will override the method pointers to point to the implementations in the next level of the hierarchy.

class Base {
public:
   Base() { f(); }
   virtual void f() { std::cout << "Base" << std::endl; } 
};
class Derived : public Base
{
public:
   Derived() : Base() {}
   virtual void f() { std::cout << "Derived" << std::endl; }
};
int main() {
   Derived d;
}
// outputs: "Base" as the vtable still points to Base::f() when Base::Base() is run

In Java, the compiler will build the virtual table equivalent at the very first step of construction, prior to entering the Base constructor or Derived constructor. The implications are different (and to my likings more dangerous). If the base class constructor calls a method that is overriden in the derived class the call will actually be handled at the derived level calling a method on an unconstructed object, yielding unexpected results. All attributes of the derived class that are initialized inside the constructor block are yet uninitialized, including 'final' attributes. Elements that have a default value defined at the class level will have that value.

public class Base {
   public Base() { polymorphic(); }
   public void polymorphic() { 
      System.out.println( "Base" );
   }
}
public class Derived extends Base
{
   final int x;
   public Derived( int value ) {
      x = value;
      polymorphic();
   }
   public void polymorphic() {
      System.out.println( "Derived: " + x ); 
   }
   public static void main( String args[] ) {
      Derived d = new Derived( 5 );
   }
}
// outputs: Derived 0
//          Derived 5
// ... so much for final attributes never changing :P

As you see, calling a polymorphic (virtual in C++ terminology) methods is a common source of errors. In C++, at least you have the guarantee that it will never call a method on a yet unconstructed object...

Really, the best practice is to step back and ask whether you really need to do this. Why do you want to modify the value of a variable that you're passing in to the function?

If you need to do it for a quick hack, the quickest way is to pass a list holding the integer, and stick a [0] around every use of it, as mgilson's answer demonstrates.

If you need to do it for something more significant, write a class that has an int as an attribute, so you can just set it. Of course this forces you to come up with a good name for the class, and for the attribute—if you can't think of anything, go back and read the sentence again a few times, and then use the list.

More generally, if you're trying to port some Java idiom directly to Python, you're doing it wrong. Even when there is something directly corresponding (as with static/@staticmethod), you still don't want to use it in most Python programs just because you'd use it in Java.

In Python 3.4+ you can use the simpler pathlib module:

from inspect import currentframe, getframeinfo
from pathlib import Path

filename = getframeinfo(currentframe()).filename
parent = Path(filename).resolve().parent

You can also use __file__ to avoid the inspect module altogether:

from pathlib import Path
parent = Path(__file__).resolve().parent

I would suggest using TRUNCATE TABLE, it's quicker and uses less resources than DELETE FROM xxx

Here's the related MSDN article

Since Java 11 you may use that:

public FileReader(String fileName, Charset charset) throws IOException;

This bug cost me 2 days. I checked my Server log, the Preflight Option request/response between browser Chrome/Edge and Server was ok. The main reason is that GET/POST/PUT/DELETE server response for XHTMLRequest must also have the following header:

access-control-allow-origin: origin  

"origin" is in the request header (Browser will add it to request for you). for example:

Origin: http://localhost:4221

you can add response header like the following to accept for all:

access-control-allow-origin: *  

or response header for a specific request like:

access-control-allow-origin: http://localhost:4221 

The message in browsers is not clear to understand: "...The requested resource"

note that: CORS works well for localhost. different port means different Domain. if you get error message, check the CORS config on the server side.

If you installed visual studio with Xamarin/mobile development support, you'll have a java install here C:\Program Files\Android\jdk\microsoft_dist_openjdk_{version}\bin\, as was my case.

Guzzle is a very well known library which makes it extremely easy to do all sorts of HTTP calls. See https://github.com/guzzle/guzzle. Install with composer require guzzlehttp/guzzle and run composer install. Now code below is enough for a http get call.

$client = new \GuzzleHttp\Client();
$response = $client->get('https://example.com/path/to/resource');

echo $response->getStatusCode();
echo $response->getBody();

In node.js you can also do the following:

const { promisify } = require('util')
const delay = promisify(setTimeout)

delay(1000).then(() => console.log('hello'))

In Bash you can use the following syntax with positional parameters:

while read -a cols; do echo ${cols[@]:2}; done < file.txt

Learn more: Handling positional parameters at Bash Hackers Wiki

readFileSync() is synchronous and blocks execution until finished. These return their results as return values. readFile() are asynchronous and return immediately while they function in the background. You pass a callback function which gets called when they finish. let's take an example for non-blocking.

following method read a file as a non-blocking way

var fs = require('fs');
fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        console.log(data);
});

following is read a file as blocking or synchronous way.

var data = fs.readFileSync(filename);

LOL...If you don't want readFileSync() as blocking way then take reference from the following code. (Native)

var fs = require('fs');
function readFileAsSync(){
    new Promise((resolve, reject)=>{
        fs.readFile(filename, "utf8", function(err, data) {
                if (err) throw err;
                resolve(data);
        });
    });
}

async function callRead(){
    let data = await readFileAsSync();
    console.log(data);
}

callRead();

it's mean behind scenes readFileSync() work same as above(promise) base.

You can set GIT_SSL_NO_VERIFY to true:

GIT_SSL_NO_VERIFY=true git clone https://example.com/path/to/git

or alternatively configure Git not to verify the connection on the command line:

git -c http.sslVerify=false clone https://example.com/path/to/git

Note that if you don't verify SSL/TLS certificates, then you are susceptible to MitM attacks.

In case of upgrading your python on mac os 10.7 and pkg_resources doesn't work, the simplest way to fix this is just reinstall setuptools as Ned mentioned above.

sudo pip install setuptools --upgrade
or sudo easy_install install setuptools --upgrade

Here is a complete solution to your question using Python's built-in functions:

# Create the List
numbers = input("Enter the elements of the list. Separate each value with a comma. Do not put a comma at the end.\n").split(",") 

# Convert the elements in the list (treated as strings) to integers
numberL = [int(element) for element in numbers] 

# Loop through the list with a for-loop

for elements in numberL:
    maxEle = max(numberL)
    indexMax = numberL.index(maxEle)

print(maxEle)
print(indexMax)

The best way is to use closures, because the window object gets very, very cluttered with properties.

The hacky, practical answer for people trying to evaluate which Heroku plan they need and can't wait for heroku's slow row counter to refresh:

Basically you want to run \dt in psql, copy the results to your favorite text editor (it will look like this:

 public | auth_group                     | table | axrsosvelhutvw
 public | auth_group_permissions         | table | axrsosvelhutvw
 public | auth_permission                | table | axrsosvelhutvw
 public | auth_user                      | table | axrsosvelhutvw
 public | auth_user_groups               | table | axrsosvelhutvw
 public | auth_user_user_permissions     | table | axrsosvelhutvw
 public | background_task                | table | axrsosvelhutvw
 public | django_admin_log               | table | axrsosvelhutvw
 public | django_content_type            | table | axrsosvelhutvw
 public | django_migrations              | table | axrsosvelhutvw
 public | django_session                 | table | axrsosvelhutvw
 public | exercises_assignment           | table | axrsosvelhutvw

), then run a regex search and replace like this:

^[^|]*\|\s+([^|]*?)\s+\| table \|.*$

to:

select '\1', count(*) from \1 union/g

which will yield you something very similar to this:

select 'auth_group', count(*) from auth_group union
select 'auth_group_permissions', count(*) from auth_group_permissions union
select 'auth_permission', count(*) from auth_permission union
select 'auth_user', count(*) from auth_user union
select 'auth_user_groups', count(*) from auth_user_groups union
select 'auth_user_user_permissions', count(*) from auth_user_user_permissions union
select 'background_task', count(*) from background_task union
select 'django_admin_log', count(*) from django_admin_log union
select 'django_content_type', count(*) from django_content_type union
select 'django_migrations', count(*) from django_migrations union
select 'django_session', count(*) from django_session
;

(You'll need to remove the last union and add the semicolon at the end manually)

Run it in psql and you're done.

            ?column?            | count
--------------------------------+-------
 auth_group_permissions         |     0
 auth_user_user_permissions     |     0
 django_session                 |  1306
 django_content_type            |    17
 auth_user_groups               |   162
 django_admin_log               |  9106
 django_migrations              |    19

Since your divs are position:absolute, they're not really nested as far as position is concerned. On your jsbin page I switched the order of the divs in the HTML to:

<div class="child"><div class="parent"></div></div>

and the red box covered the blue box, which I think is what you're looking for.

For me it worked:

 df['id'].convert_dtypes()

see the documentation here:

I tried installing the nodemon globally but that doesn't worked for me. whenever i try to run it always shows me the error:

nodemon : The term 'nodemon' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling
of the name, or if a path was included, verify that the path is
correct and try again.

2. I have found two solutions for this

solution 1:

What i have tried is to update the "scripts" in package.json file and there i have added

"server": "nodemon app.js"

above line of code and after that

npm run server

Soluton 2:

1. Press the Windows key.

2. Type "Path" in the search box and select "Edit the system environment variables"

3. Click on "Environment Variables" near the bottom.

4. In the "System Variables" section double click on the "Path" variable.

5. Click "New" on the right-hand side.

6. Copy and paste this into the box (replace [Username]):

C:\Users[Username]\AppData\Roaming\npm

7. restart your terminal and VSCode.

8. Then type nodemon app.js to run the nodemon

i applied solution 2 as we just need to run nodemon [filename.js]

Since you're comparing numbers, you can use an arithmetic expression, which allows for simpler handling of parameters and comparison:

wget -q --tries=10 --timeout=20 --spider http://google.com
if (( $? != 0 )); then
    echo "Sorry you are Offline"
    exit 1
fi

Notice how instead of -ne, you can just use !=. In an arithmetic context, we don't even have to prepend $ to parameters, i.e.,

var_a=1
var_b=2
(( var_a < var_b )) && echo "a is smaller"

works perfectly fine. This doesn't appply to the $? special parameter, though.

Further, since (( ... )) evaluates non-zero values to true, i.e., has a return status of 0 for non-zero values and a return status of 1 otherwise, we could shorten to

if (( $? )); then

but this might confuse more people than the keystrokes saved are worth.

The (( ... )) construct is available in Bash, but not required by the POSIX shell specification (mentioned as possible extension, though).

This all being said, it's better to avoid $? altogether in my opinion, as in Cole's answer and Steven's answer.

I was having the same question. Here is a working solution which is similar to eglasius's. I am using postgresql.

UPDATE QuestionTrackings
SET QuestionID = a.QuestionID
FROM QuestionTrackings q, QuestionAnswers a
WHERE q.QuestionID IS NULL

It complains if q was used in place of table name in line 1, and nothing should precede QuestionID in line 2.

I don't know what you mean by inefficient but if you mean in terms of typing it could be easier to just select the cols of interest and assign back to the df:

df = df[cols_of_interest]

Where cols_of_interest is a list of the columns you care about.

Or you can slice the columns and pass this to drop:

df.drop(df.ix[:,'Unnamed: 24':'Unnamed: 60'].head(0).columns, axis=1)

The call to head just selects 0 rows as we're only interested in the column names rather than data

update

Another method: It would be simpler to use the boolean mask from str.contains and invert it to mask the columns:

In [2]:
df = pd.DataFrame(columns=['a','Unnamed: 1', 'Unnamed: 1','foo'])
df

Out[2]:
Empty DataFrame
Columns: [a, Unnamed: 1, Unnamed: 1, foo]
Index: []

In [4]:
~df.columns.str.contains('Unnamed:')

Out[4]:
array([ True, False, False,  True], dtype=bool)

In [5]:
df[df.columns[~df.columns.str.contains('Unnamed:')]]

Out[5]:
Empty DataFrame
Columns: [a, foo]
Index: []

You can call tail +[line number] [file] and pipe it to grep -n which shows the line number:

tail +[line number] [file] | grep -n /regex/

The only problem with this method is the line numbers reported by grep -n will be [line number] - 1 less than the actual line number in [file].

For windows specifically: \path\to\python.exe -m pip install PackageName works.

I found I needed to remove static declarations if I wanted to see the variables, but this works better...

Modify/view static variables while debugging in Eclipse

Verifying ele is visible.

public static boolean isElementVisible(final By by)
    throws InterruptedException {
        boolean value = false;

        if (driver.findElements(by).size() > 0) {
            value = true;
        }
        return value;
    }

Find the <SHA#> for the commit you want to go. You can find it in github or by typing git log or git reflog show at the command line and then do git reset --hard <SHA#>

In my case, the error was in using angular2-notifications 0.9.8 instead of 0.9.7

There are several ways to do this. I converted like this

def clean(s):
    s = s.replace("u'","")
    return re.sub("[\[\]\'\s]", '', s)

EmployeeList = [clean(i) for i in str(EmployeeList).split(',')]

After that you can check

if '1001' in EmployeeList:
    #do something

Hope it will help you.

You should use urllib.reuqest, not urllib3.

import urllib.request   # not urllib - important!
urllib.request.urlopen('https://...')

Your idea to use enumerate() was correct.

indices = []
for i, elem in enumerate(mylist):
    if 'aa' in elem:
        indices.append(i)

Alternatively, as a list comprehension:

indices = [i for i, elem in enumerate(mylist) if 'aa' in elem]

I've used Beanstalkd for one project, and planned to again. I've found it to be an excellent way to run asynchronous processes.

A couple of things I've done with it are:

• Image resizing - and with a lightly loaded queue passing off to a CLI-based PHP script, resizing large (2mb+) images worked just fine, but trying to resize the same images within a mod_php instance was regularly running into memory-space issues (I limited the PHP process to 32MB, and the resizing took more than that)
• near-future checks - beanstalkd has delays available to it (make this job available to run only after X seconds) - so I can fire off 5 or 10 checks for an event, a little later in time

I wrote a Zend-Framework based system to decode a 'nice' url, so for example, to resize an image it would call QueueTask('/image/resize/filename/example.jpg'). The URL was first decoded to an array(module,controller,action,parameters), and then converted to JSON for injection to the queue itself.

A long running cli script then picked up the job from the queue, ran it (via Zend_Router_Simple), and if required, put information into memcached for the website PHP to pick up as required when it was done.

One wrinkle I did also put in was that the cli-script only ran for 50 loops before restarting, but if it did want to restart as planned, it would do so immediately (being run via a bash-script). If there was a problem and I did exit(0) (the default value for exit; or die();) it would first pause for a couple of seconds.

My privilege prevents me making my comment on the first post so it will have to go here.

Consideration should be taken into account of 2038 unix bug when setting 20 years in advance from the current date which is suggest as the correct answer above.

Your cookie on January 19, 2018 + (20 years) could well hit 2038 problem depending on the browser and or versions you end up running on.

I used the advice of Kevin Jones above with the following --skip-networking change for slightly better security:

sudo systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --skip-networking"

[user@machine ~]$ mysql -u root

Then when attempting to reset the password I received an error, but googling elsewhere suggested I could simply forge ahead. The following worked:

mysql> select user(), current_user();
+--------+-----------------------------------+
| user() | current_user()                    |
+--------+-----------------------------------+
| root@  | skip-grants user@skip-grants host |
+--------+-----------------------------------+
1 row in set (0.00 sec)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.02 sec)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
Query OK, 0 rows affected (0.08 sec)

mysql> exit
Bye
[user@machine ~]$ systemctl stop mysqld
[user@machine ~]$ sudo systemctl unset-environment MYSQLD_OPTS
[user@machine ~]$ systemctl start mysqld

At that point I was able to log in.

1. Go to the Build Path settings in the project properties.
2. Remove the JRE System Library
3. Add it back; Select "Add Library" and select the JRE System Library. The default worked for me.

This works because you have multiple classes in different jar files. Removing and re-adding the jre lib will make the right classes be first. If you want a fundamental solution make sure you exclude the jar files with the same classes.

Also, when checking for the last image, you must compare with imgArray.length-1 because, for example, when array length is 2 then I will take the values 0 and 1, it won't reach the value 2, so you must compare with length-1 not with length, here is the fixed line:

if(i == imgArray.length-1)

strcpy example:

#include <stdio.h>
#include <string.h>

int main ()
{
  char str1[]="Sample string" ;
  char str2[40] ;
  strcpy (str2,str1) ;
  printf ("str1: %s\n",str1) ;
  return 0 ;
}

Output: str1: Sample string

Your case:

A simple = operator should do the job.

string str1="Sample string" ;
string str2 = str1 ;

using is used for importing namespaces not classes.

So if your class is in namespace X

namespace X
{
    public class MyClass {
         void stuff() {

         }
    }
}

then to use it in another namespace where you want it

using System;
using X;

public class MyMainClass {
    static void Main() {
        MyClass test = new MyClass();
    }
}

Here is another solution using Guava in Java 8 that returns the matched element if one exists in the list. If more than one elements are matched then the collector throws an IllegalArgumentException. A null is returned if there is no match.

Carnet carnet = listCarnet.stream()
                    .filter(c -> c.getCodeIsin().equals(wantedCodeIsin))
                    .collect(MoreCollectors.toOptional())
                    .orElse(null);

Basically, it works like,

<table align="center">
...

But, you can do it in better way using CSS, and this will be a better approach to use CSS as it provides dynamic behavior to a web page and is responsive.

  <table style="text-align:center;">

Also, if you need to display only table on a page then you can go with body tag alignment only as shown below,

 <body style="text-align:center;">
<table>
  ...
</table>

If you want any other suggestions please let me know. Will surely help you on this. Also using bootstrap features this would be more easy and interactive.

Like all other had said above, you need to add path. But not sure for what reason if I add C:\xampp\php in path of System Variable won't work but if I add it in path of User Variable work fine.

Although I had added and using other command line tools by adding in system variables work fine

So just in case if someone had same problem as me. Windows 10

This error can also happen if the server only sends its leaf certificate and does not send all the chain certificates needed to build the trust chain to the root CA. Unfortunately this is a common misconfiguration of servers.

Most browsers work around this problem if they already know the missing chain certificate from earlier visits or maybe download the missing certificate if the leaf certificate contains a URL for CA issuers in Authority Information Access (AIA). But this behavior is usually restricted to desktop browsers and other tools simply fail because they cannot build the trust chain.

You can make the JRE to automatically download the intermediate certificate by setting com.sun.security.enableAIAcaIssuers to true

To verify if the server is sending all the chain certificates you can enter the host in the following SSL certificate validation tool https://www.digicert.com/help/

In the context of Drupal, the difference will depend whether clean URLs are on or not.

With them off, $_SERVER['REQUEST_URI'] will have the full path of the page as called w/ /index.php, while $_GET["q"] will just have what is assigned to q.

With them on, they will be nearly identical w/o other arguments, but $_GET["q"] will be missing the leading /. Take a look towards the end of the default .htaccess to see what is going on. They will also differ if additional arguments are passed into the page, eg when a pager is active.

The only problem is that even after authenticating with Spring Security, the user/principal bean doesn't exist in the container, so dependency-injecting it will be difficult. Before we used Spring Security we would create a session-scoped bean that had the current Principal, inject that into an "AuthService" and then inject that Service into most of the other services in the Application. So those Services would simply call authService.getCurrentUser() to get the object. If you have a place in your code where you get a reference to the same Principal in the session, you can simply set it as a property on your session-scoped bean.

CSS selector:

Use a CSS selector of img[src='images/toolbar/b_edit.gif']

This says select element(s) with img tag with attribute src having value of 'images/toolbar/b_edit.gif'

CSS query:

VBA:

You can apply the selector with the .querySelector method of document.

IE.document.querySelector("img[src='images/toolbar/b_edit.gif']").Click

Though this might be too late to comment but here's the working code for problems such as yours.

    <audio autoplay hidden>
     <source src="link/to/file/file.mp3" type="audio/mpeg">
                If you're reading this, audio isn't supported.

You can use the NuGet Package Manager extension.

After you've installed it, to add a package, press Ctrl+Shift+P, and type >nuget and press Enter:

Type a part of your package's name as search string:

Choose the package:

And finally the package version (you probably want the newest one):

You could simply use XmlHttp (AJAX) to hit the required URL and the HTML response from the URL will be available in the responseText property. If it's not the same domain, your users will receive a browser alert saying something like "This page is trying to access a different domain. Do you want to allow this?"

!== should match the value and data type

!= just match the value ignoring the data type

$num = '1';
$num2 = 1;

$num == $num2; // returns true    
$num === $num2; // returns false because $num is a string and $num2 is an integer

System.out.println(Integer.toBinaryString(343));

Just define a helper in application helper directory then call from your controller just function name like

helper name = new_helper.php
function test_method($data){
 return $data
}   

in controller load the helper

$this->load->new_helper();
$result =  test_method('Hello world!');
if($result){
 echo $result
}

output will be

Hello World!

If you're in a situation like @Keith you could try:

print(a.__dict__)

It goes against what I would consider good style but if you're just trying to debug then it should do what you want.

echo "$PWD" | sed 's!.*/!!'

If you are using Bourne shell or ${PWD##*/} is not available.

Sounds like we need to assume that your textbox name and ID are both set to "Tue." If that's the case, try using a lower-case V on .value.

For SVG elements

Using something like selection.node().getBBox() you get values like

{
    height: 5, 
    width: 5, 
    y: 50, 
    x: 20
} 

For HTML elements

Use selection.node().getBoundingClientRect()

Just make sure you add box-sizing:border-box; to your #myWorkContent.

If you are into performance, then it is worth using ENUM type. It will probably be faster on big tables, due to the better index performance.

The way of using it (source: http://dev.mysql.com/doc/refman/5.5/en/enum.html):

CREATE TABLE shirts (
    name VARCHAR(40),
    size ENUM('x-small', 'small', 'medium', 'large', 'x-large')
);

But, I always say that explaining the query like this:

EXPLAIN SELECT * FROM shirts WHERE size='medium';

will tell you lots of information about your query and help on building a better table structure. For this end, it is usefull to let phpmyadmin Propose a table table structure - but this is more a long time optimisation possibility, when the table is already filled with lots of data.

Steps :

1. Write style="text-align:center;" to parent div of ul
2. Write style="display:inline-table;" to ul
3. Write style="display:inline;" to li

or use

<div class="menu">
 <ul>
   <li>item 1 </li>
   <li>item 2 </li>
   <li>item 3 </li>
 </ul>
</div>

<style>
 .menu { text-align: center; }
 .menu ul { display:inline-table; }
 .menu li { display:inline; }
</style>

N=np.floor(np.divide(l,delta))
...
for j in range(N[i]/2):

N[i]/2 will be a float64 but range() expects an integer. Just cast the call to

for j in range(int(N[i]/2)):

As simple as that

  private static byte[] getByteArrayFromByteBuffer(ByteBuffer byteBuffer) {
    byte[] bytesArray = new byte[byteBuffer.remaining()];
    byteBuffer.get(bytesArray, 0, bytesArray.length);
    return bytesArray;
}

When you're running npm install in the project's root, it installs all of the npm dependencies into the project's node_modules directory.

If you take a look at the project's node_modules directory, you should see a directory called http-server, which holds the http-server package, and a .bin folder, which holds the executable binaries from the installed dependencies. The .bin directory should have the http-server binary (or a link to it).

So in your case, you should be able to start the http-server by running the following from your project's root directory (instead of npm start):

./node_modules/.bin/http-server -a localhost -p 8000 -c-1

This should have the same effect as running npm start.

If you're running a Bash shell, you can simplify this by adding the ./node_modules/.bin folder to your $PATH environment variable:

export PATH=./node_modules/.bin:$PATH

This will put this folder on your path, and you should be able to simply run

http-server -a localhost -p 8000 -c-1

The following should work fine:

git diff -z --name-only commit1 commit2 | xargs -0 -IREPLACE rsync -aR REPLACE /home/changes/protected/

To explain further:

• The -z to with git diff --name-only means to output the list of files separated with NUL bytes instead of newlines, just in case your filenames have unusual characters in them.

• The -0 to xargs says to interpret standard input as a NUL-separated list of parameters.

• The -IREPLACE is needed since by default xargs would append the parameters to the end of the rsync command. Instead, that says to put them where the later REPLACE is. (That's a nice tip from this Server Fault answer.)

• The -a parameter to rsync means to preserve permissions, ownership, etc. if possible. The -R means to use the full relative path when creating the files in the destination.

Update: if you have an old version of xargs, you'll need to use the -i option instead of -I. (The former is deprecated in later versions of findutils.)

In your CSS file, such as App.css in a create-react-app, add a fontface import. For example:

@fontface {
  font-family: 'Bungee Inline', cursive;
  src: url('https://fonts.googleapis.com/css?family=Bungee+Inline')
}

Then simply add the font to the DOM element within the same css file.

body {
  font-family: 'Bungee Inline', cursive;
}

If you didn't set the modalPresentationStyle property (like to UIModalPresentationFormSheet), the navigation bar will be displayed always. To ensure, always do

[[self.navigationController topViewController] presentViewController:vieController 
                                                            animated:YES 
                                                          completion:nil];

This will show the navigation bar always.

Here are Windows wheel packages built by Chris Golke - Python Windows Binary packages - PyQt

In the filenames cp27 means C-python version 2.7, cp35 means python 3.5, etc.

Since Qt is a more complicated system with a compiled C++ codebase underlying the python interface it provides you, it can be more complex to build than just a pure python code package, which means it can be hard to install it from source.

Make sure you grab the correct Windows wheel file (python version, 32/64 bit), and then use pip to install it - e.g:

C:\path\where\wheel\is\> pip install PyQt4-4.11.4-cp35-none-win_amd64.whl

Should properly install if you are running an x64 build of Python 3.5.

Aligning to 6 bytes is not weird, because it is aligning to addresses multiple to 4.

So basically you have 34 bytes in your structure and the next structure should be placed on the address, that is multiple to 4. The closest value after 34 is 36. And this padding area counts into the size of the structure.

background-image takes multiple values.

so a combination of just 1 color linear-gradient and css blend modes will do the trick.

.testclass {
    background-image: url("../images/image.jpg"), linear-gradient(rgba(0,0,0,0.5),rgba(0,0,0,0.5));
    background-blend-mode: overlay;
}

note that there is no support on IE/Edge for CSS blend-modes at all.

use .filter(':has(:checkbox:checked)' ie:

$('#mytable tr').filter(':has(:checkbox:checked)').each(function() {
 $('#out').append(this.id);
});

With Spring MVC 4.2.1.RELEASE, you need to use the new Jackson2 dependencies as below for the Deserializer to work.

Dont use this

<dependency>  
            <groupId>org.codehaus.jackson</groupId>  
            <artifactId>jackson-mapper-asl</artifactId>  
            <version>1.9.12</version>  
        </dependency>  

Use this instead.

<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.2.2</version>
        </dependency>  

Also use com.fasterxml.jackson.databind.JsonDeserializer and com.fasterxml.jackson.databind.annotation.JsonDeserialize for the deserialization and not the classes from org.codehaus.jackson

A negative look ahead is a correct answer, but it can be written more cleanly like:

This looks for an occurrence of \ and then in a check that does not get matched, it looks for any number of characters followed by the character you don't want to see after it. Because it's negative, it only matches if it does not find a match.

GPS, the Global Positioning System run by the United States Military, is free for civilian use, though the reality is that we're paying for it with tax dollars.

However, GPS on cell phones is a bit more murky. In general, it won't cost you anything to turn on the GPS in your cell phone, but when you get a location it usually involves the cell phone company in order to get it quickly with little signal, as well as get a location when the satellites aren't visible (since the gov't requires a fix even if the satellites aren't visible for emergency 911 purposes). It uses up some cellular bandwidth. This also means that for phones without a regular GPS receiver, you cannot use the GPS at all if you don't have cell phone service.

For this reason most cell phone companies have the GPS in the phone turned off except for emergency calls and for services they sell you (such as directions).

This particular kind of GPS is called assisted GPS (AGPS), and there are several levels of assistance used.

GPS

A normal GPS receiver listens to a particular frequency for radio signals. Satellites send time coded messages at this frequency. Each satellite has an atomic clock, and sends the current exact time as well.

The GPS receiver figures out which satellites it can hear, and then starts gathering those messages. The messages include time, current satellite positions, and a few other bits of information. The message stream is slow - this is to save power, and also because all the satellites transmit on the same frequency and they're easier to pick out if they go slow. Because of this, and the amount of information needed to operate well, it can take 30-60 seconds to get a location on a regular GPS.

When it knows the position and time code of at least 3 satellites, a GPS receiver can assume it's on the earth's surface and get a good reading. 4 satellites are needed if you aren't on the ground and you want altitude as well.

AGPS

As you saw above, it can take a long time to get a position fix with a normal GPS. There are ways to speed this up, but unless you're carrying an atomic clock with you all the time, or leave the GPS on all the time, then there's always going to be a delay of between 5-60 seconds before you get a location.

In order to save cost, most cell phones share the GPS receiver components with the cellular components, and you can't get a fix and talk at the same time. People don't like that (especially when there's an emergency) so the lowest form of GPS does the following:

1. Get some information from the cell phone company to feed to the GPS receiver - some of this is gross positioning information based on what cellular towers can 'hear' your phone, so by this time they already phone your location to within a city block or so.
2. Switch from cellular to GPS receiver for 0.1 second (or some small, practically unoticable period of time) and collect the raw GPS data (no processing on the phone).
3. Switch back to the phone mode, and send the raw data to the phone company
4. The phone company processes that data (acts as an offline GPS receiver) and send the location back to your phone.

This saves a lot of money on the phone design, but it has a heavy load on cellular bandwidth, and with a lot of requests coming it requires a lot of fast servers. Still, overall it can be cheaper and faster to implement. They are reluctant, however, to release GPS based features on these phones due to this load - so you won't see turn by turn navigation here.

More recent designs include a full GPS chip. They still get data from the phone company - such as current location based on tower positioning, and current satellite locations - this provides sub 1 second fix times. This information is only needed once, and the GPS can keep track of everything after that with very little power. If the cellular network is unavailable, then they can still get a fix after awhile. If the GPS satellites aren't visible to the receiver, then they can still get a rough fix from the cellular towers.

But to completely answer your question - it's as free as the phone company lets it be, and so far they do not charge for it at all. I doubt that's going to change in the future. In the higher end phones with a full GPS receiver you may even be able to load your own software and access it, such as with mologogo on a motorola iDen phone - the J2ME development kit is free, and the phone is only $40 (prepaid phone with $5 credit). Unlimited internet is about $10 a month, so for $40 to start and $10 a month you can get an internet tracking system. (Prices circa August 2008)

It's only going to get cheaper and more full featured from here on out...

Re: Google maps and such

Yes, Google maps and all other cell phone mapping systems require a data connection of some sort at varying times during usage. When you move far enough in one direction, for instance, it'll request new tiles from its server. Your average phone doesn't have enough storage to hold a map of the US, nor the processor power to render it nicely. iPhone would be able to if you wanted to use the storage space up with maps, but given that most iPhones have a full time unlimited data plan most users would rather use that space for other things.

If you are having this problem in react-native projects with one of the external library. You should remove the project and use react-native link <package-name> again. That should solve the problem.

With the Angular CLI it's easy. An example for Heroku:

1. Create a Heroku account and install the CLI

2. Move the angular-cli dep to the dependencies in package.json (so that it gets installed when you push to Heroku.

3. Add a postinstall script that will run ng build when the code gets pushed to Heroku. Also add a start command for a Node server that will be created in the following step. This will place the static files for the app in a dist directory on the server and start the app afterward.

"scripts": {
  // ...
  "start": "node server.js",
  "postinstall": "ng build --aot -prod"
}

4. Create an Express server to serve the app.

// server.js
const express = require('express');
const app = express();
// Run the app by serving the static files
// in the dist directory
app.use(express.static(__dirname + '/dist'));
// Start the app by listening on the default
// Heroku port
app.listen(process.env.PORT || 8080);

5. Create a Heroku remote and push to depoy the app.

heroku create
git add .
git commit -m "first deploy"
git push heroku master

Here's a quick writeup I did that has more detail, including how to force requests to use HTTPS and how to handle PathLocationStrategy :)

Try below one:

svn copy http://svn.example.com/repos/calc/trunk@rev-no 
       http://svn.example.com/repos/calc/branches/my-calc-branch 
  -m "Creating a private branch of /calc/trunk."  --parents

No slash "\" between the svn URLs.

On a Windows machine I was able to log to to ssh from git bash with
ssh vagrant@VAGRANT_SERVER_IP without providing a password

Using Bitvise SSH client on window
Server host: VAGRANT_SERVER_IP
Server port: 22
Username: vagrant
Password: vagrant

You can use extensions for this.

extension NSDate {
    //NSString to NSDate
    convenience
    init(dateString:String) {
        let nsDateFormatter = NSDateFormatter()
        nsDateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        // Add the locale if required here
        let dateObj = nsDateFormatter.dateFromString(dateString)
        self.init(timeInterval:0, sinceDate:dateObj!)
    }

    //NSDate to time string
    func getTime() -> String {
        let timeFormatter = NSDateFormatter()
        timeFormatter.dateFormat = "hh:mm"
        //Can also set the default styles for date or time using .timeStyle or .dateStyle
        return timeFormatter.stringFromDate(self)
    }

    //NSDate to date string
    func getDate() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd, MMM"
        return dateFormatter.stringFromDate(self)
    }

    //NSDate to String
    func getString() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        return dateFormatter.stringFromDate(self)
    }
}

So while execution actual code will look like follows

    var dateObjFromString = NSDate(dateString: cutDateTime)
    var dateString = dateObjFromString.getDate()
    var timeString = dateObjFromString.getTime()
    var stringFromDate = dateObjFromString.getString()

There are some defaults methods as well but I guess it might not work for the format you have given from documentation

    -dateFromString(_:)
    -stringFromDate(_:)
    -localizedStringFromDate(_ date: NSDate,
                     dateStyle dateStyle: NSDateFormatterStyle,
                     timeStyle timeStyle: NSDateFormatterStyle) -> String

I found a useful function present in web3 library.

var hexString = "0x1231ac"
string strValue = web3.toAscii(hexString)

Use *

var allElem = document.getElementsByTagName("*");
for (var i = 0; i < allElem.length; i++) {
    // Do something with all element here
}

I eventually figured it out. Place:

import warnings
warnings.filterwarnings('ignore')

inside ~/.ipython/profile_default/startup/disable-warnings.py. I'm leaving this question and answer for the record in case anyone else comes across the same issue.

Quite often it is useful to see a warning once. This can be set by:

warnings.filterwarnings(action='once')

Note: To make the most voted solution work, attributes in the POJO have to be public or have a public getter/setter:

By default, Jackson 2 will only work with fields that are either public, or have a public getter method – serializing an entity that has all fields private or package private will fail.

Not tested yet, but I believe that this rule also applies for other JSON libs like google Gson.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

as an aside, i Couldnt import the .dll if it was already in the plugins folder. I put it in a temp folder on the C drive, and it worked perfectly.

You can use http://docs.mitmproxy.org/en/stable/install.html

Its easy to setup and won't require any extra tweaks.

I go through various tool but found it to be really good and easy.

1. Press the Apps menu button on your Android mobile phone device. It will display icons of all the apps installed on your mobile phone device. Press Settings.

2. Press Apps. (Pressing on Apps button will list down all the apps installed on your mobile phone.

3. Browse the Apps list and press on the app called "Launcher 3". (Launcher 3 is an app and it will be listed in the App list whenever you access Settings > Apps in your android phone).

4. Pressing on the "Launcher 3" app will open the "App info screen" which will show some details pertaining to that app. On this App info screen, you will find buttons like "Force Stop", "Uninstall", "Clear Data" and "Clear Cache" etc.

5. In Android Marshmallow (i.e. Android 6.0) choose Settings > Apps > Launcher3 > STORAGE. Press "Clear Cache". If this fails, press "Clear data". This will eventually restore functionality, but all custom shortcuts will be lost.

Restart the phone and its done. All the home screens along with app shortcuts will appear again and your mobile phone is at your service again.

I hope it explains well on how to solve the launcher problem in Android. Worked for me.

Angular now has a type of iterate Object for exactly this scenario, called a Set. It fit my needs when I found this question searching. You create the set, "add" to it like you'd "push" to an array, and drop it in an ngFor just like an array. No pipes or anything.

this.myObjList = new Set();

...

this.myObjList.add(obj);

...

<ul>
   <li *ngFor="let object of myObjList">
     {{object}}
   </li>
</ul>

I know this is a very old thread. I found this way very helpful for me:

1. Go to Window ? Preferences ? Java ? Editor ? Save Actions.
2. Check the option "Perform the selected actions on save".
3. Check the option "Organize imports".

Now every time you save your classes, eclipse will take care of removing the unused imports.

If you want a copy-paste bash script:

var=$(mysql -e 'SELECT CONCAT("ALTER TABLE ", TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_czech_ci;") AS execTabs FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA="zabbix" AND TABLE_TYPE="BASE TABLE"' -uroot -p )

var+='ALTER DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_general_ci;'

echo $var | cut -d " " -f2- | mysql -uroot -p zabbix

Change zabbix to your database name.

As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined keyword.

tasks:
    - shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
      when: foo is defined

    - fail: msg="Bailing out. this play requires 'bar'"
      when: bar is undefined

Ansible Documentation

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

Output:

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

When you execute a script without typing "python" in front, you need to know two things about how Windows invokes the program. First is to find out what kind of file Windows thinks it is:

    C:\>assoc .py
    .py=Python.File

Next, you need to know how Windows is executing things with that extension. It's associated with the file type "Python.File", so this command shows what it will be doing:

    C:\>ftype Python.File
    Python.File="c:\python26\python.exe" "%1" %*

So on my machine, when I type "blah.py foo", it will execute this exact command, with no difference in results than if I had typed the full thing myself:

    "c:\python26\python.exe" "blah.py" foo

If you type the same thing, including the quotation marks, then you'll get results identical to when you just type "blah.py foo". Now you're in a position to figure out the rest of your problem for yourself.

(Or post more helpful information in your question, like actual cut-and-paste copies of what you see in the console. Note that people who do that type of thing get their questions voted up, and they get reputation points, and more people are likely to help them with good answers.)

Brought In From Comments:

Even if assoc and ftype display the correct information, it may happen that the arguments are stripped off. What may help in that case is directly fixing the relevant registry keys for Python. Set the

HKEY_CLASSES_ROOT\Applications\python26.exe\shell\open\command

key to:

"C:\Python26\python26.exe" "%1" %*

Likely, previously, %* was missing. Similarly, set

 HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

to the same value. See http://eli.thegreenplace.net/2010/12/14/problem-passing-arguments-to-python-scripts-on-windows/

HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command The registry path may vary, use python26.exe or python.exe or whichever is already in the registry.

HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

As google says:

Paste it into your web page, just before the closing </head> tag.

One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. It is customary to place JavaScript code in the <head> section, and we recommend placing the snippet at the bottom of the <head> section for best performance

None of the answers seemed to work well with buttons. Bootstrap v4.1.1

<div class="card bg-light">
    <div class="card-body">
        <button type="submit" class="btn btn-primary">
            Save

            Cancel
        </a>
    </div>
</div>

Model.uniq.pluck(:rating)

# SELECT DISTINCT "models"."rating" FROM "models"

This has the advantages of not using sql strings and not instantiating models

If you don't mind using OFFSET(), which is a volatile function that recalculates everytime a cell is changed, then this is a good solution that is both dynamic and reusable:

=OFFSET($COL:$COL, ROW(), 1, 1048576 - ROW(), 1)

where $COL is the letter of the column you are going to operate upon, and ROW() is the row function that dynamically selects the same row as the cell containing this formula. You could also replace the ROW() function with a static number ($ROW).

=OFFSET($COL:$COL, $ROW, 1, 1048576 - $ROW, 1)

You could further clean up the formula by defining a named constant for the 1048576 as 'maxRows'. This can be done in the 'Define Name' menu of the Formulas tab.

=OFFSET($COL:$COL, $ROW, 1, maxRows - $ROW, 1)

A quick example: to Sum from C6 to the end of column C, you could do:

=SUM(OFFSET(C:C, 6, 1, maxRows - 6, 1))

or =SUM(OFFSET(C:C, ROW(), 1, maxRows - ROW(),1))

This solution has been working for me:

1. Run the app in the simulator
2. Open the system log (? + /)

This will dump out all of the debug data and also your NSLogs.

To filter just your NSLog statements:

1. Prefix each with a symbol, for example: NSLog(@"^ Test Log")
2. Filter the results using the search box on the top right, "^" in the case above

This is what you should get:

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

MrOBrian's answer shows why your current code doesn't work, with the missing trailing ] and quotes, but here's an easier way to make it work:

onchange='mySelectHandler(this)'

And then:

function mySelectHandler(el){
     var mySelect = $(el)
     // get selected value
     alert ("selected " + mySelect.val())
  }

Or better still, remove the inline event handler altogether and bind the event handler with jQuery:

$('select[name="a[b]"]').change(function() {
    var mySelect = $(this);
    alert("selected " mySelect.val());
});

That last would need to be in a document.ready handler or in a script block that appears after the select element. If you want to run the same function for other selects simply change the selector to something that applies to all, e.g., all selects would be $('select'), or all with a particular class would be $('select.someClass').

After testing most of the switches this worked for me:

xcopy C:\folder1 C:\folder2\folder1 /t /e /i /y

This will copy the folder folder1 into the folder folder2. So the directory tree would look like:

C:
   Folder1
   Folder2
      Folder1

Well it depends on what you have in your table.

its one of the following If you have only one table

var count = $('#gvPerformanceResult tr').length;

If you are concerned about sub tables but this wont work with tbody and thead (if you use them)

var count = $('#gvPerformanceResult>tr').length;

Where by this will work (but is quite frankly overkill.)

var count = $('#gvPerformanceResult>tbody>tr').length;

• Serial Communication in Windows

¹⁾ You can use this with Windows (incl. MinGW) as well as Linux. Alternative you can only use the code as an example.

²⁾ Step-by-step tutorial how to use serial ports on windows

³⁾ You can use this literally on MinGW

Here's some very, very simple code (without any error handling or settings):

#include <windows.h>

/* ... */


// Open serial port
HANDLE serialHandle;

serialHandle = CreateFile("\\\\.\\COM1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);

// Do some basic settings
DCB serialParams = { 0 };
serialParams.DCBlength = sizeof(serialParams);

GetCommState(serialHandle, &serialParams);
serialParams.BaudRate = baudrate;
serialParams.ByteSize = byteSize;
serialParams.StopBits = stopBits;
serialParams.Parity = parity;
SetCommState(serialHandle, &serialParams);

// Set timeouts
COMMTIMEOUTS timeout = { 0 };
timeout.ReadIntervalTimeout = 50;
timeout.ReadTotalTimeoutConstant = 50;
timeout.ReadTotalTimeoutMultiplier = 50;
timeout.WriteTotalTimeoutConstant = 50;
timeout.WriteTotalTimeoutMultiplier = 10;

SetCommTimeouts(serialHandle, &timeout);

Now you can use WriteFile() / ReadFile() to write / read bytes. Don't forget to close your connection:

CloseHandle(serialHandle);

Good Luck!

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

I am very suprised nobody came up with this kind of solution to bind it against bool array. It might not be the cleanest, but it can be used very easily:

private bool[] _modeArray = new bool[] { true, false, false};
public bool[] ModeArray
{
    get { return _modeArray ; }
}
public int SelectedMode
{
    get { return Array.IndexOf(_modeArray, true); }
}

in XAML:

<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[0], Mode=TwoWay}"/>
<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[1], Mode=TwoWay}"/>
<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[2], Mode=TwoWay}"/>

NOTE: you dont need two-way binding if you dont want to one checked by default. TwoWay binding is the biggest cons of this solution.

Pros:

• No need for code behind
• No need for extra class (IValue Converter)
• No Need for extra enums
• doesnt require bizzare binding
• straightforward and easy to understand
• doesnt violate MVVM (heh, at least I hope so)

It works like this:

h4 {
    display:inline;
}
h4:after {
    content:"\a";
    white-space: pre;
}

Example: http://jsfiddle.net/Bb2d7/

The trick comes from here: https://stackoverflow.com/a/66000/509752 (to have more explanation)

Using this way You will do a endless Loop on Your JS. to do a better way you can use the following

var on_submit_function = function(evt){
    evt.preventDefault(); //The form wouln't be submitted Yet.
    (...yourcode...)

    $(this).off('submit', on_submit_function); //It will remove this handle and will submit the form again if it's all ok.
    $(this).submit();
}

$('form').on('submit', on_submit_function); //Registering on submit.

I hope it helps! Thanks!

I think the differences are:

Code first

• Very popular because hardcore programmers don't like any kind of designers and defining mapping in EDMX xml is too complex.
• Full control over the code (no autogenerated code which is hard to modify).
• General expectation is that you do not bother with DB. DB is just a storage with no logic. EF will handle creation and you don't want to know how it does the job.
• Manual changes to database will be most probably lost because your code defines the database.

Database first

• Very popular if you have DB designed by DBAs, developed separately or if you have existing DB.
• You will let EF create entities for you and after modification of mapping you will generate POCO entities.
• If you want additional features in POCO entities you must either T4 modify template or use partial classes.
• Manual changes to the database are possible because the database defines your domain model. You can always update model from database (this feature works quite well).
• I often use this together VS Database projects (only Premium and Ultimate version).

Model first

• IMHO popular if you are designer fan (= you don't like writing code or SQL).
• You will "draw" your model and let workflow generate your database script and T4 template generate your POCO entities. You will lose part of the control on both your entities and database but for small easy projects you will be very productive.
• If you want additional features in POCO entities you must either T4 modify template or use partial classes.
• Manual changes to database will be most probably lost because your model defines the database. This works better if you have Database generation power pack installed. It will allow you updating database schema (instead of recreating) or updating database projects in VS.

I expect that in case of EF 4.1 there are several other features related to Code First vs. Model/Database first. Fluent API used in Code first doesn't offer all features of EDMX. I expect that features like stored procedures mapping, query views, defining views etc. works when using Model/Database first and DbContext (I haven't tried it yet) but they don't in Code first.

In TortiseSVN settings

right-click menu >> settings >> Saved data >> Authentication data [Clear]

The side effect is that it clears out all authentication data and you have to re-enter your own username/password.

.length is undefined because getMinutes is returning a number, not a string. numbers don't have a length property. You could do

var m = "" + date.getMinutes();

to make it a string, then check the length (you would want to check for length === 1, not 0).

More "Try it Yourself" examples below.

Definition and Usage The split() method is used to split a string into an array of substrings, and returns the new array.

Tip: If an empty string ("") is used as the separator, the string is split between each character.

Note: The split() method does not change the original string.

var res = str.split(",");

If you have installed a module on Xampp (on Linux) via Bitnami and changed chown settings, make sure that the /opt/lampp/apps/<app>/htdocs and tmp usergroup is daemon with all other sibling files and folders chowned to the user you installed as, e.g. cd /opt/lampp/apps/<app>, sudo chown -R root:root ., followed by sudo chown -R root:daemon htdocs tmp.

Try this:

SELECT ProductName,NumberofProducts ,NumberofProductssold
   FROM table1 
     JOIN table2
     ON table1.ProductName = table2.ProductName

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

If you are trying to save a file to the file system. Path.Combine is not bullet proof as it won't help you if the file name contains invalid characters. Here is an extension method that strips out invalid characters from file names:

public static string ToSafeFileName(this string s)
{
        return s
            .Replace("\\", "")
            .Replace("/", "")
            .Replace("\"", "")
            .Replace("*", "")
            .Replace(":", "")
            .Replace("?", "")
            .Replace("<", "")
            .Replace(">", "")
            .Replace("|", "");
    }

And the usage can be:

Path.Combine(str_uploadpath, fileName.ToSafeFileName());

Run time is the instance where you don't know about of what type of objects creates during its execution, objects creation are based on certain condition or some computation work. In contradict, compile time is the instance where required objects are defined by you before its executions.

You should check if the callback exists, and is an executable function:

if (callback && typeof(callback) === "function") {
    // execute the callback, passing parameters as necessary
    callback();
}

A lot of libraries (jQuery, dojo, etc.) use a similar pattern for their asynchronous functions, as well as node.js for all async functions (nodejs usually passes error and data to the callback). Looking into their source code would help!

I also faced the same issue but in VS2013.

I did the below way to fix, It was worked fine.

1. Close all the opened Visual studio instance.

2. Then, go to "Developer command prompt" from visual studio tools,

3. Type it as devenv.exe /resetuserdata

4. Restart the machine, Open the Visual studio then It will ask you to choose the development settings from initial onwards, thereafter open any solution/project. You'll be amazed.

Hope, it might helps you :)

I don't see df.write.saveAsTable(...) deprecated in Spark 2.0 documentation. It has worked for us on Amazon EMR. We were perfectly able to read data from S3 into a dataframe, process it, create a table from the result and read it with MicroStrategy. Vinays answer has also worked though.

Presently Package name starting with "com.example" is not allowed to upload in the app -store. Otherwise , all other package names starting with "com" are allowed .

First Add a Class called Win32.cs

public class Win32
{ 
    [DllImport("User32.Dll")]
    public static extern long SetCursorPos(int x, int y);

    [DllImport("User32.Dll")]
    public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int x;
        public int y;

        public POINT(int X, int Y)
        {
            x = X;
            y = Y;
        }
    }
}

You can use it then like this:

Win32.POINT p = new Win32.POINT(xPos, yPos);

Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);

I don't think you can its an operator and its suppose to return one or the other. It's not if else statement replacement although it can be use for that on certain case.

The most simple way is to use Record type Record<number, productDetails >

interface productDetails {
   productId : number , 
   price : number , 
   discount : number
};

const myVar : Record<number, productDetails> = {
   1: {
       productId : number , 
       price : number , 
       discount : number
   }
}

Download latest version of postman from https://www.postman.com/downloads/ then after tar.gz file gets downloaded follow below commands

Serialization is taking a "live" object in memory and converting it to a format that can be stored somewhere (eg. in memory, on disk) and later "deserialized" back into a live object.

do this , please note that you will have to define the regex for 'test'!!!

string s = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
string[] parts = (new Regex("")).Split(s);
//just do a count on parts

I suggest you do some experiments using "make". Here is a simple demo, showing the difference between = and :=.

/* Filename: Makefile*/
x := foo
y := $(x) bar
x := later

a = foo
b = $(a) bar
a = later

test:
    @echo x - $(x)
    @echo y - $(y)
    @echo a - $(a)
    @echo b - $(b)

make test prints:

x - later
y - foo bar
a - later
b - later bar

The best way I know to sort HTML table with javascript is with the following function.

Just pass to it the id of the table you'd like to sort and the column number on the row. it assumes that the column you are sorting is numeric or has numbers in it and will do regex replace to get the number itself (great for currencies and other numbers with symbols in it).

function sortTable(table_id, sortColumn){
    var tableData = document.getElementById(table_id).getElementsByTagName('tbody').item(0);
    var rowData = tableData.getElementsByTagName('tr');            
    for(var i = 0; i < rowData.length - 1; i++){
        for(var j = 0; j < rowData.length - (i + 1); j++){
            if(Number(rowData.item(j).getElementsByTagName('td').item(sortColumn).innerHTML.replace(/[^0-9\.]+/g, "")) < Number(rowData.item(j+1).getElementsByTagName('td').item(sortColumn).innerHTML.replace(/[^0-9\.]+/g, ""))){
                tableData.insertBefore(rowData.item(j+1),rowData.item(j));
            }
        }
    }
}

Using example:

$(function(){
    // pass the id and the <td> place you want to sort by (td counts from 0)
    sortTable('table_id', 3);
});

Well, it depends on what language you are using, but in general they are 2 separate configurations, each with its own settings. By default, Debug includes debug information in the compiled files (allowing easy debugging) while Release usually has optimizations enabled.

As far as conditional compilation goes, they each define different symbols that can be checked in your program, but they are language-specific macros.

i found a simple way:

delete require.cache['/home/shimin/test2.js']

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.

It's actually best practice to provide the os with a path link.

With windows 10

1. open up file explorer
2. right click on "this pc" and select "properties"
3. Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
4. At the bottom of the next window, click on the "Environment Variables" button.
5. On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
6. Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
7. Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.

You can use assertThrows(), which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit.

Per the JUnit docs:

import static org.junit.jupiter.api.Assertions.assertThrows;

@Test
void exceptionTesting() {
    MyException thrown = assertThrows(
           MyException.class,
           () -> myObject.doThing(),
           "Expected doThing() to throw, but it didn't"
    );

    assertTrue(thrown.getMessage().contains("Stuff"));
}

earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException. You're calling group(1) without having first called a matching operation (such as find()). This isn't needed if you're just using $1 since the replaceAll() is the matching operation.

It is a tradition to use Turbo C for graphic in C/C++. But it’s also a pain in the neck. We are using Code::Blocks IDE, which will ease out our work.

Steps to run graphics code in CodeBlocks:

1. Install Code::Blocks
2. Download the required header files
3. Include graphics.h and winbgim.h
4. Include libbgi.a
5. Add Link Libraries in Linker Setting
6. include graphics.h and Save code in cpp extension

To test the setting copy paste run following code:

#include <graphics.h>
int main( )
{
    initwindow(400, 300, "First Sample");
    circle(100, 50, 40);
    while (!kbhit( ))
    {
        delay(200);
    }
    return 0;
}

Here is a complete setup instruction for Code::Blocks

How to include graphics.h in CodeBlocks?

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

"Select your text, right click, then choose Style Token and then using 1st style (2nd style, etc …). At the moment is not possible to save the style tokens but there is an idea pending on Idea torrent you may vote for if your are interested in that."

It should be default, but it might be hidden.

"It might be that something happened to your contextMenu.xml so that you only get the basic standard. Have a look in NPPs config folder (%appdata%\Notepad++\) if the contextMenu.xml is there. If no: that would be the answer; if yes: it might be defect. Anyway you can grab the original standart contextMenu.xml from here and place it into the config folder (or replace the existing xml). Start NPP and you should have quite a long context menu. Tip: have a look at the contextmenu.xml itself - because you're allowed to change it to your own needs."

Normal multiplication like you showed:

>>> import numpy as np
>>> m = np.array([[1,2,3],[4,5,6],[7,8,9]])
>>> c = np.array([0,1,2])
>>> m * c
array([[ 0,  2,  6],
       [ 0,  5, 12],
       [ 0,  8, 18]])

If you add an axis, it will multiply the way you want:

>>> m * c[:, np.newaxis]
array([[ 0,  0,  0],
       [ 4,  5,  6],
       [14, 16, 18]])

You could also transpose twice:

>>> (m.T * c).T
array([[ 0,  0,  0],
       [ 4,  5,  6],
       [14, 16, 18]])

Here's a more robust routine to cancel default behavior and event bubbling in all browsers:

// Prevents event bubble up or any usage after this is called.
eventCancel = function (e)
{
    if (!e)
        if (window.event) e = window.event;
        else return;
    if (e.cancelBubble != null) e.cancelBubble = true;
    if (e.stopPropagation) e.stopPropagation();
    if (e.preventDefault) e.preventDefault();
    if (window.event) e.returnValue = false;
    if (e.cancel != null) e.cancel = true;
}

An example of how this would be used in an event handler:

// Handles the click event for each tab
Tabstrip.tabstripLinkElement_click = function (evt, context) 
{
    // Find the tabStrip element (we know it's the parent element of this link)
    var tabstripElement = this.parentNode;
    Tabstrip.showTabByLink(tabstripElement, this);
    return eventCancel(evt);
}

I have faced the same issue and also not using virtual environment. easy_install is working for me.

easy_install boto3

NestedCaveats solution worked for me.

Imported my .dll files before importing torch and gpytorch, and all went smoothly.

So I just want to add that its not just importing pytorch but I can confirm that torch and gpytorch have this issue as well. I'd assume it covers any other torch-related libraries.

Because you are creatin a table expression, you have to specify the structure of that table, you can achive this on two way:

1: In the select you can use the original columnnames (as in your first example), but with aggregates you have to use an alias (also in conflicting names). Like

sum(totalitems) as bkdqty

2: You need to specify the column names rigth after the name of the talbe, and then you just have to take care that the count of the names should mach the number of coulms was selected in the query. Like:

d (duration, bkdqty) 
AS (Select.... ) 

With the second solution both of your query will work!

Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET command. The first one to stop the service, the second one to start the service. Give them a STOP and START argument, followed by the service name.

In this example we restart the Printer Spooler service.

NET STOP "Print Spooler" 
NET START "Print Spooler"

Note: unfortunately NET RESTART <service name> does not exist.

I wanted to add that there is another possibility - to use the function na().

e.g. =if(a2 = 5,"good",na());

This will fill the cell with #N/A and if you chart the column, the data won't be graphed. I know it isn't "blank" as such, but it's another possibility if you have blank strings in your data and "" is a valid option.

Also, count(a:a) will not count cells which have been set to n/a by doing this.

You just need to use the socket settimeout() method before attempting the connect(), please note that after connecting you must settimeout(None) to set the socket into blocking mode, such is required for the makefile . Here is the code I am using:

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(10)
sock.connect(address)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

You found the shorthand to set privileges for all existing tables in the given schema. The manual clarifies:

(but note that ALL TABLES is considered to include views and foreign tables).

Bold emphasis mine. serial columns are implemented with nextval() on a sequence as column default and, quoting the manual:

For sequences, this privilege allows the use of the currval and nextval functions.

So if there are serial columns, you'll also want to grant USAGE (or ALL PRIVILEGES) on sequences

GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;

Note: identity columns in Postgres 10 or later use implicit sequences that don't require additional privileges. (Consider upgrading serial columns.)

What about new objects?

You'll also be interested in DEFAULT PRIVILEGES for users or schemas:

ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT ALL PRIVILEGES ON TABLES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT USAGE          ON SEQUENCES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo REVOKE ...;

This sets privileges for objects created in the future automatically - but not for pre-existing objects.

Default privileges are only applied to objects created by the targeted user (FOR ROLE my_creating_role). If that clause is omitted, it defaults to the current user executing ALTER DEFAULT PRIVILEGES. To be explicit:

ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo GRANT ...;
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo REVOKE ...;

Note also that all versions of pgAdmin III have a subtle bug and display default privileges in the SQL pane, even if they do not apply to the current role. Be sure to adjust the FOR ROLE clause manually when copying the SQL script.

public void UploadFtpFile(string folderName, string fileName)
{

    FtpWebRequest request;

    string folderName; 
    string fileName;
    string absoluteFileName = Path.GetFileName(fileName);

    request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/{2}", "127.0.0.1", folderName, absoluteFileName))) as FtpWebRequest;
    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UseBinary = 1;
    request.UsePassive = 1;
    request.KeepAlive = 1;
    request.Credentials =  new NetworkCredential(user, pass);
    request.ConnectionGroupName = "group"; 

    using (FileStream fs = File.OpenRead(fileName))
    {
        byte[] buffer = new byte[fs.Length];
        fs.Read(buffer, 0, buffer.Length);
        fs.Close();
        Stream requestStream = request.GetRequestStream();
        requestStream.Write(buffer, 0, buffer.Length);
        requestStream.Flush();
        requestStream.Close();
    }
}

How to use

UploadFtpFile("testFolder", "E:\\filesToUpload\\test.img");

use this in your foreach

and you only need to create folder one time

to create a folder

request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/", "127.0.0.1", "testFolder"))) as FtpWebRequest;
request.Method = WebRequestMethods.Ftp.MakeDirectory;
FtpWebResponse ftpResponse = (FtpWebResponse)request.GetResponse();

For byte Array type data you can use magic.from_buffer(_byte_array,mime=True)

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.

However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.

In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.

Example Code

Here is a simple example based on a SAP system I have access to.

Public Sub SimpleSAPExport()
  Set SapGuiAuto  = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
  Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI 
  Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
  Set session = SAPCon.Children(0) 'Get the first session (window) on that connection

  'Start the transaction to view a table
  session.StartTransaction "SE16"

  'Select table T001
  session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
  session.findById("wnd[0]/tbar[1]/btn[7]").Press

  'Set our selection criteria
  session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
  session.findById("wnd[0]/tbar[1]/btn[8]").press

  'Click the export to file button
  session.findById("wnd[0]/tbar[1]/btn[45]").press

  'Choose the export format
  session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
  session.findById("wnd[1]/tbar[0]/btn[0]").press

  'Choose the export filename
  session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
  session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"

  'Export the file
  session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub

Script Recording

To help find the names of elements such aswnd[1]/tbar[0]/btn[0] you can use script recording. Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.

Within that the More button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.

Edit: Early and Late binding

The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI") defines the SapGuiAuto object.

If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx in the SAP GUI installation folder.

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

This is the best solution provided by Google Developers. Simply call this method in onResume of onCreate after initializing GoogleApiClient.

private void updateMarkers() {
    if (mMap == null) {
        return;
    }

    if (mLocationPermissionGranted) {

                        } catch (IntentSender.SendIntentException e) {
                            // Ignore the error.


                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way
                        // to fix the settings so we won't show the dialog.


                        break;

            }
        });

Note : This line of code automatic open the dialog box if Location is not on. This piece of line is used in Google Map also

 status.startResolutionForResult(
 MainActivity.this,
 PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);

Since git 1.8 you can do

git submodule update --remote --merge

This will update the submodule to the latest remote commit. You will then need to commit the change so the gitlink in the parent repository is updated

git commit

And then push the changes as without this, the SHA-1 identity the pointing to the submodule won't be updated and so the change won't be visible to anyone else.

parentElement is new to Firefox 9 and to DOM4, but it has been present in all other major browsers for ages.

In most cases, it is the same as parentNode. The only difference comes when a node's parentNode is not an element. If so, parentElement is null.

As an example:

document.body.parentNode; // the <html> element
document.body.parentElement; // the <html> element

document.documentElement.parentNode; // the document node
document.documentElement.parentElement; // null

(document.documentElement.parentNode === document);  // true
(document.documentElement.parentElement === document);  // false

Since the <html> element (document.documentElement) doesn't have a parent that is an element, parentElement is null. (There are other, more unlikely, cases where parentElement could be null, but you'll probably never come across them.)

All your firebase version should be with same Version whatever it

like this

compile 'com.google.firebase:firebase-core:9.0.0'
compile 'com.google.firebase:firebase-database:9.0.0'
compile 'com.google.firebase:firebase-auth:9.0.0'
compile 'com.google.firebase:firebase-messaging:9.0.0' 

[project properties dialog]

For development using VisualStudio 2017 and a NetCore API-project:

1) In Cmd-Box: ipconfig /all to determine IP-address

2a) Enter the retrieved IP-address in Project properties-> Debug Tab

2b) Select a Port and attach that to the IP-address from step 2a.

3) Add an allow rule in the firewall to allow incoming TCP-traffic on the selected Port (my firewall triggered with a dialog: "Block or add rule to firewall"). Add will in that case do the trick.

Disadvantage of the solution above:

1) If you use a dynamic IP-address you need to redo the steps above in case another IP-address has been assigned.

2) You server has now an open Port which you might forget, but this open port remains an invitation for unwanted guests.

I came across the same when tried add GitVersion tool to update my version in AssemblyInfo.cs. Use VS2017 and .NET Core project. So I just mixed both worlds. My AssemblyInfo.cs contains only version info that was generated by GitVersion tool, my csproj contains remaingin things. Please note I don't use <GenerateAssemblyInfo>false</GenerateAssemblyInfo> I use attributes related to version only (see below). More details here AssemblyInfo properties.

AssemblyInfo.cs

[assembly: AssemblyVersion("0.2.1.0")]
[assembly: AssemblyFileVersion("0.2.1.0")]
[assembly: AssemblyInformationalVersion("0.2.1+13.Branch.master.Sha.119c35af0f529e92e0f75a5e6d8373912d457818")]

my.csproj contains all related to other assemblyu attributes:

<PropertyGroup>
...
<Company>SOME Company </Company>
<Authors>Some Authors</Authors>
<Product>SOME Product</Product>
...
<GenerateAssemblyVersionAttribute>false</GenerateAssemblyVersionAttribute>
<GenerateAssemblyFileVersionAttribute>false</GenerateAssemblyFileVersionAttribute><GenerateAssemblyInformationalVersionAttribute>false</GenerateAssemblyInformationalVersionAttribute>

You could do what React warns you when you try to set the "selected" property of the <option>:

Use the defaultValue or value props on <select> instead of setting selected on <option>.

So, you can use options.value on the defaultValue of your select

With Java 6 form I think is better to check it is closed or not before close (for example if some connection pooler evict the connection in other thread) - for example some network problem - the statement and resultset state can be come closed. (it is not often happens, but I had this problem with Oracle and DBCP). My pattern is for that (in older Java syntax) is:

try {
    //...   
    return resp;
} finally {
    if (rs != null && !rs.isClosed()) {
        try {
            rs.close();
        } catch (Exception e2) { 
            log.warn("Cannot close resultset: " + e2.getMessage());
        }
    }
    if (stmt != null && !stmt.isClosed()) {
        try {
            stmt.close();
        } catch (Exception e2) {
            log.warn("Cannot close statement " + e2.getMessage()); 
        }
    }
    if (con != null && !conn.isClosed()) {
        try {
            con.close();
        } catch (Exception e2) {
            log.warn("Cannot close connection: " + e2.getMessage());
        }
    }
}

In theory it is not 100% perfect because between the the checking the close state and the close itself there is a little room for the change for state. In the worst case you will get a warning in long. - but it is lesser than the possibility of state change in long run queries. We are using this pattern in production with an "avarage" load (150 simultanous user) and we had no problem with it - so never see that warning message.

When using Monkey Script I noticed that DispatchPress(KEYCODE_BACK) is doing nothing which really suck. In many cases this is due to the fact that the Activity doesn't consume the Key event. The solution to this problem is to use a mix of monkey script and adb shell input command in a sequence.

1 Using monkey script gave some great timing control. Wait a certain amount of second for the activity and is a blocking adb call.
2 Finally sending adb shell input keyevent 4 will end the running APK.

EG

adb shell monkey -p com.my.application -v -v -v -f /sdcard/monkey_script.txt 1
adb shell input keyevent 4

In your jQuery use:

$("body").css("cursor", "progress");

and then back to normal again

$("body").css("cursor", "default");

The only solution that worked for me (node 12.x, npm 6.x) was using npm-force-resolutions developed by @Rogerio Chaves.

First, install it by:

npm install npm-force-resolutions --save-dev

You can add --ignore-scripts if some broken transitive dependency scripts are blocking you from installing anything.

Then in package.json define what dependency should be overridden (you must set exact version number):

"resolutions": {
  "your-dependency-name": "1.23.4"
}

and in "scripts" section add new preinstall entry:

"preinstall": "npx npm-force-resolutions",

Now, npm install will apply changes and force your-dependency-name to be at version 1.23.4 for all dependencies.

A simpler if statement from AskUbuntu: How do I check whether a module is installed in Python?

import sys
print('eggs' in sys.modules)

Syntactically a little different but it looks cleaner in my opinion:

render 'my_partial', locals: { title: "My awesome title" }

# not a big fan of the arrow key syntax
render 'my_partial', :locals => { :title => "My awesome title" }

I just solved this problem very elegantly after a lot of trial and error.

Check out my blog post: http://geon.github.io/programming/2016/02/24/flexbox-full-page-web-app-layout

Basically, to make a flexbox cell scrollable, you have to make all its parents overflow: hidden;, or it will just ignore your overflow settings and make the parent larger instead.

I have not tried, but if you know Perl you can use the Parse-Stata-DtaReader module to convert the file for you.

The module has a command-line tool dta2csv, which can "convert Stata 8 and Stata 10 .dta files to csv"

"A picture is worth a thousand words".

I have a simple example here, it's similar to your case.

string s1 = "abc";
string s2 = s1;
s1 = "def";
Console.WriteLine(s2);
// Output: abc

This is what happened:

• Line 1 and 2: s1 and s2 variables reference to the same "abc" string object.
• Line 3: Because strings are immutable, so the "abc" string object do not modify itself (to "def"), but a new "def" string object is created instead, and then s1 references to it.
• Line 4: s2 still references to "abc" string object, so that's the output.

I know this is really late, but with C# 7.3 you can do this for unmanaged structs or anything else that's unmanged (int, bool etc...):

public static unsafe byte[] ConvertToBytes<T>(T value) where T : unmanaged {
        byte* pointer = (byte*)&value;

        byte[] bytes = new byte[sizeof(T)];
        for (int i = 0; i < sizeof(T); i++) {
            bytes[i] = pointer[i];
        }

        return bytes;
    }

Then use like this:

struct MyStruct {
        public int Value1;
        public int Value2;
        //.. blah blah blah
    }

    byte[] bytes = ConvertToBytes(new MyStruct());

One thing you should be very aware of when dealing with encryption:

Trying to be clever and inventing your own thing usually will leave you with something insecure.

You'd probably be best off using one of the cryptography extensions that come with PHP.

Instead for rewriting all my path code as suggested, I changed the working directory:

if getattr(sys, 'frozen', False):
    os.chdir(sys._MEIPASS)

Just add those two lines at the beginning of your code, you can leave the rest as is.

1. Locate the my.ini, which store in the MySQL installation folder.

For Example, C:\Program Files\MySQL\MySQL Server 5.1\my.ini

2. Open the “my.ini” with our favor text editor.

#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.1/"
 
#Path to the database root
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data/"

Find the “datadir”, this is the where does MySQL stored the data in Windows.

Linux

1. Locate the my.cnf with the find / -name my.cnf command.

yongmo@myserver:~$ find / -name my.cnf
find: /home/lost+found: Permission denied
find: /lost+found: Permission denied
/etc/mysql/my.cnf

2. View the my.cnf file like this: cat /etc/mysql/my.cnf

yongmo@myserver:~$ cat /etc/mysql/my.cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
[mysqld]
#
# * Basic Settings
#
user   = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket  = /var/run/mysqld/mysqld.sock
port   = 3306
basedir  = /usr
datadir  = /var/lib/mysql
tmpdir  = /tmp
language = /usr/share/mysql/english

3. Find the “datadir”, this is where does MySQL stored the data in Linux system.

Here is a well tested function which i used for my projects with detailed self explanatory comments

There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}

You're using junit.framework.Assert instead of org.junit.Assert.

The top-scoring answer has the right idea, but the API seems to have evolved so that it no longer works as when it was first written, in 2015.

In place of this:

from OpenSSL import SSL
context = SSL.Context(SSL.PROTOCOL_TLSv1_2)
context.use_privatekey_file('server.key')
context.use_certificate_file('server.crt')

I used this, with Python 3.7.5:

import ssl
context = ssl.SSLContext()
context.load_cert_chain('fullchain.pem', 'privkey.pem')

and then supplied the SSL context in the Flask.run call as it said:

app.run(…, ssl_context=context)

(My server.crt file is called fullchain.pem and my server.key is called privkey.pem. These files were supplied to me by my LetsEncrypt Certbot.)

I was getting same error for

import Firebase

But then noticed that I was not adding pod to the main target section but only adding to Test and TestUI targets in Podfile.

With the command

pod init

for an xcode swift project, the following Podfile is generated

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyAppUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

So, need to make sure that one adds pods to any appropriate placeholder.

I had your issue, i fixed it . this error comes when your target api level is not completely downloaded . you have two ways: go to your SDK menu and download all of the android 9 components or the better way is go to your build.gradle(Module app) and change it like this:But remember, before applying these changes, make sure you have fully downloaded api lvl 8

I also faced a similar issue. While for anyone this may be an issue of various bad usages in Code such as

1. Wrong Layout tag in XML
2. Loading of heavy resource directly into ImageView resulting in OOM
3. Issues with usage of styles.

One most ignored factor may be usage of correct Context while inflating views. Please check that you are not using ApplicationContext where an Activity context is required. While, ApplicationContext may not end up in error always, but depending upon your view hierarchy it may be crucial.

I resolved my issue with a BAD context (using ApplicationContext instead of Activity in a span of 4 days! So try if that solves. Happy Coding!!

This is all that you had to do man, change his MyViewModel model to IList.

I tried the following code and it worked for me.

<button class="btn btn-default center-block" type="submit">Button</button>

The button control is in a div and using center-block class of bootstrap helped me to align the button to the center of div

Check the link where you will find the center-block class

http://getbootstrap.com/css/#helper-classes-center

I like a single line open and close:

if [ ]; then ##
    ...
    ...
fi; ##

The '##' helps me easily find the start and end to the block comment. I can stick a number after the '##' if I've got a bunch of them. To turn off the comment, I just stick a '1' in the '[ ]'. I also avoid some issues I've had with single-quotes in the commented block.

Try this one add this code to your manifest file

 <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>

provide your path type path.xml

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

and add this code to your functionality

File file = new File(tempPathNameFileString);
Intent viewPdf = new Intent(Intent.ACTION_VIEW);
viewPdf.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
Uri URI = FileProvider.getUriForFile(ReportsActivity.this, ReportsActivity.this.getApplicationContext().getPackageName() + ".provider", file);
viewPdf.setDataAndType(URI, "application/pdf");
viewPdf.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
ReportsActivity.this.startActivity(viewPdf);

That is the backbone of CSS, the "cascade" in Cascading Style Sheets.

If you write your CSS rules in a single line it makes it easier to see the structure:

.area1 .item { color:red; }
.area2 .item { color:blue; }
.area2 .item span { font-weight:bold; }

Using multiple classes is also a good intermediate/advanced use of CSS, unfortunately there is a well known IE6 bug which limits this usage when writing cross browser code:

<div class="area1 larger"> .... </div>

.area1 { width:200px; }
.area1.larger { width:300px; }

IE6 IGNORES the first selector in a multi-class rule, so IE6 actually applies the .area1.larger rule as

/*.area1*/.larger { ... }

Meaning it will affect ALL .larger elements.

It's a very nasty and unfortunate bug (one of many) in IE6 that forces you to pretty much never use that feature of CSS if you want one clean cross-browser CSS file.

The solution then is to use CSS classname prefixes to avoid colliding wiht generic classnames:

.area1 { ... }
.area1.area1Larger { ... }

.area2.area2Larger { ... }

May as well use just one class, but that way you can keep the CSS in the logic you intended, while knowing that .area1Larger only affects .area1, etc.

To build once a day between say 4PM to 6PM you can use

H H(15-17) * * *

Using Laravel 5.1, you can use

\Request::route()->getName()

Controller

public ActionResult Index()
    {


        //you don't need to include the category bc it does it by itself
        //var model = db.Product.Include(c => c.Category).ToList()

        ViewBag.Categories = db.Category.OrderBy(c => c.Name).ToList();
        var model = db.Product.ToList()
        return View(model);
    }

View

you need to filter the model with the given category

like :=> Model.where(p=>p.CategoryID == category.CategoryID)

try this...

@foreach (var category in ViewBag.Categories)
{
    <h3><u>@category.Name</u></h3>

    <div>

        @foreach (var product in Model.where(p=>p.CategoryID == category.CategoryID))
        {

                <table cellpadding="5" cellspacing"5" style="border:1px solid black; width:100%;background-color:White;">
                    <thead>
                        <tr>
                            <th style="background-color:black; color:white;">
                                @product.Title  
                                @if (System.Web.Security.UrlAuthorizationModule.CheckUrlAccessForPrincipal("/admin", User, "GET"))
                                {
                                    @Html.Raw(" - ")  
                                    @Html.ActionLink("Edit", "Edit", new { id = product.ID }, new { style = "background-color:black; color:white !important;" })
                                }
                            </th>
                        </tr>
                    </thead>

                    <tbody>
                        <tr>
                            <td style="background-color:White;">
                                @product.Description
                            </td>
                        </tr>
                    </tbody>      
                </table>                       
            }


    </div>
}  

For Windows, if directory is not empty, and you have read-only files or you get errors like

• Access is denied
• The process cannot access the file because it is being used by another process

Try this, os.system('rmdir /S /Q "{}"'.format(directory))

It's equivalent for rm -rf in Linux/Mac.

this works for me, so try it :

Microsoft.Office.Interop.Excel.Range rng =(Microsoft.Office.Interop.Excel.Range)XcelApp.Cells[1, i];
rng.Font.Bold = true; 
rng.Interior.Color =System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Yellow);
rng.BorderAround(); 

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

I know that this question has been asked for a long time but as of today one simple answer is:

<img src="image.png" style="width: 55vw; min-width: 330px;" />

The use of vw in here tells that the width is relative to 55% of the width of the viewport.

All the major browsers nowadays support this.

Suppose you have already created a table now you can use this query to make composite primary key

alter table employee add primary key(emp_id,emp_name);
