I believe you are not the only one who has problems when trying to deploy Crystal Report for VS 2010. Based on the error message you had, have you checked:

1. Please make sure you just have one CR version installed on your system. If you do have other CR version installed, consider to uninstall it so that your application is not "confused" about the CR version.

2. You need to make sure you download the correct CR version. Since you are using VS 2010, you need to refer to CRforVS_redist_install_64bit_13_0_1.zip (for 64 bit machine) or CRforVS_redist_install_32bit_13_0_1.zip (for 32 bit machine). These two are the redistributable packages. You can download full package from the below link as well: CRforVS_13_0_1.exe Note: It is sometimes necessary to install 32bit CR runtime even on 64bit OS

3. Make sure you setup FULL TRUST permission on your root folder

4. The LOCAL SERVICE permission must be setup on your application pool

5. Make sure the aspnet_client folder exists on your root folder.

If you can make sure all the 5 points above, your Crystal Report should work without any fuss.

Another important thing to note down here is that if you host your Crystal Report with a shared host, you need to check it with them of whether they really support Crystal Report. If you still have problems, you can switch to http://www.asphostcentral.com, who provides Crystal Report support.

Good luck!

Use the Database menu and "Set Datasource Location" menu option to change the name or location of each table in a report.

This works for changing the location of a database, changing to a new database, and changing the location or name of an individual table being used in your report.

To change the datasource connection, go the Database menu and click Set Datasource Location.

1. Change the Datasource Connection:
   1. From the Current Data Source list (the top box), click once on the datasource connection that you want to change.
   2. In the Replace with list (the bottom box), click once on the new datasource connection.
   3. Click Update.
2. Change Individual Tables:
   4. From the Current Data Source list (the top box), expand the datasource connection that you want to change.
   5. Find the table for which you want to update the location or name.
   6. In the Replace with list (the bottom box), expand the new datasource connection.
   7. Find the new table you want to update to point to.
   8. Click Update.
   9. Note that if the table name has changed, the old table name will still appear in the Field Explorer even though it is now using the new table. (You can confirm this be looking at the Table Name of the table's properties in Current Data Source in Set Datasource Location. Screenshot http://i.imgur.com/gzGYVTZ.png) It's possible to rename the old table name to the new name from the context menu in Database Expert -> Selected Tables.
3. Change Subreports:
   9. Repeat each of the above steps for any subreports you might have embedded in your report.
   10. Close the Set Datasource Location window.
4. Any Commands or SQL Expressions:
   11. Go to the Database menu and click Database Expert.
   12. If the report designer used "Add Command" to write custom SQL it will be shown in the Selected Tables box on the right.
   13. Right click that command and choose "Edit Command".
   14. Check if that SQL is specifying a specific database. If so you might need to change it.
   15. Close the Database Expert window.
   16. In the Field Explorer pane on the right, right click any SQL Expressions.
   17. Check if the SQL Expressions are specifying a specific database. If so you might need to change it also.
   18. Save and close your Formula Editor window when you're done editing.

And try running the report again.

The key is to change the datasource connection first, then any tables you need to update, then the other stuff. The connection won't automatically change the tables underneath. Those tables are like goslings that've imprinted on the first large goose-like animal they see. They'll continue to bypass all reason and logic and go to where they've always gone unless you specifically manually change them.

To make it more convenient, here's a tip: You can "Show SQL Query" in the Database menu, and you'll see table names qualified with the database (like "Sales"."dbo"."Customers") for any tables that go straight to a specific database. That might make the hunting easier if you have a lot of stuff going on. When I tackled this problem I had to change each and every table to point to the new table in the new database.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

"SP25 work on Visual Studio 2019" is an exaggeration. It is extremely unreliable and should be avoided at all costs. I currently have to maintain a second development environment with V2015 for report development.

I think you are looking for ToText(CCur(@Price}/{ValuationReport.YestPrice}*100-100))

You can use CCur to convert numbers or string to Curency formats. CCur(number) or CCur(string)

I think this may be what you are looking for,

Replace (ToText(CCur({field})),"$" , "") that will give the parentheses for negative numbers

It is a little hacky, but I'm not sure CR is very kind in the ways of formatting

I believe this is what you're looking for:

Convert Decimal Numbers to Text showing only the non-zero decimals

Especially this line might be helpful:

StringVar text     :=  Totext ( {Your.NumberField} , 6 , ""  )  ;

The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.

Visual Studio 2017 is supported in Crystal Reports SP 21, which is available for download as of 1 Sep 2017.

Sometimes the field is not recognized by crystal reports as DATE, so you can add a formula with function: Date({YourField}), And add it to the report, now when you open the format object dialog you will find the date formatting options.

In case anyone else is looking for this... as of April 2013, you can still get the free Visual Studio edition of Crystal Reports from this web site: SAP Crystal Reports - Downloads (updated url).

It installs into Visual Studio 2010 or VS 2012, and you can edit and save RPT files with as much capability as the standard Crystal Reports editor.

When you are in the Command, click Create to create a new parameter; call it project_name. Once you've created it, double click its name to add it to the command's text. You query should resemble:

SELECT Projecttname, ReleaseDate, TaskName
FROM DB_Table
WHERE Project_Name LIKE {?project_name} + '*'
AND ReleaseDate >= getdate() --assumes sql server

If desired, link the main report to the subreport on this ({?project_name}) field. If you don't establish a link between the main and subreport, CR will prompt you for the subreport's parameter.

In versions prior to 2008, a command's parameter was only allowed to be a scalar value.

Enabling the legacy from app.config didn't work for me. For unknown reasons, my application wasn't activating V2 runtime policy. I found a work around here.

Enabling the legacy from app.config is a recommended approach but in some cases it doesn't work as expected. Use the following code with in your main application to force Legacy V2 policy:

public static class RuntimePolicyHelper
{
public static bool LegacyV2RuntimeEnabledSuccessfully { get; private set; }

static RuntimePolicyHelper()
{
    ICLRRuntimeInfo clrRuntimeInfo =
        (ICLRRuntimeInfo)RuntimeEnvironment.GetRuntimeInterfaceAsObject(
            Guid.Empty, 
            typeof(ICLRRuntimeInfo).GUID);
    try
    {
        clrRuntimeInfo.BindAsLegacyV2Runtime();
        LegacyV2RuntimeEnabledSuccessfully = true;
    }
    catch (COMException)
    {
        // This occurs with an HRESULT meaning 
        // "A different runtime was already bound to the legacy CLR version 2 activation policy."
        LegacyV2RuntimeEnabledSuccessfully = false;
    }
}

[ComImport]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
[Guid("BD39D1D2-BA2F-486A-89B0-B4B0CB466891")]
private interface ICLRRuntimeInfo
{
    void xGetVersionString();
    void xGetRuntimeDirectory();
    void xIsLoaded();
    void xIsLoadable();
    void xLoadErrorString();
    void xLoadLibrary();
    void xGetProcAddress();
    void xGetInterface();
    void xSetDefaultStartupFlags();
    void xGetDefaultStartupFlags();

    [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)]
    void BindAsLegacyV2Runtime();
}
}

JasperReports if you're writing Java.

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

Somehow I had the wrong versions of the DLLs registered in my project.

• I removed the three references to the Crystal Report dlls from my project.
• I right click References, and click Add Reference
• In the popup window, I click the Browse menu on the left and the Browse button
• In the Directory window where your DLLs reside (perhaps your application's bin directory), select the three Crystal Reports DLLs and then click Add.
• Back at the Reference Manager window, click in the first column to the left of the three Crystal dlls, and then click OK
• At this point your Crystal Reports should work again.

If IsNull({TABLE.FIELD1}) then "NULL" +',' + {TABLE.FIELD2} else {TABLE.FIELD1} + ', ' + {TABLE.FIELD2}

Here I put NULL as string to display the string value NULL in place of the null value in the data field. Hope you understand.

You simply need to install Crystal Report Report Run Time downloads on Deployment Server. If problem still appears, then place check asp_client folder in your project main folder.

I have found a variety of runtimes including Visual Studio(VS) versions are available at http://scn.sap.com/docs/DOC-7824

(Assuming you are looking at the reports in the Crystal Report Designer...)

Your menu options might be a little different depending on the version of Crystal Reports you're using, but you can either:

• Make a summary field: Right-click on the desired formula field in your detail section and choose "Insert Summary". Choose "sum" from the drop-down box and verify that the correct account grouping is selected, then click OK. You will then have a simple sum field in your group footer section.
• Make a running total field: Click on the "Insert" menu and choose "Running Total Field..."*** Click on the New button and give your new running total field a name. Choose your formula field under "Field to summarize" and choose "sum" under "Type of Summary". Here you can also change when the total is evaluated and reset, leave these at their default if you're wanting a sum on each record. You can also use a formula to determine when a certain field should be counted in the total. (Evaluate: Use Formula)

I see two options here

var link = $('a').attr('href');
var equalPosition = link.indexOf('='); //Get the position of '='
var number = link.substring(equalPosition + 1); //Split the string and get the number.

I dont know if you're gonna use it for paging and have the text in the <a>-tag as you have it, but if you should you can also do

var number = $('a').text();

Using ...
search = (^.*import )(.*)(\(.*\):)
replace = $1$2

...replaces ...

from checks import checklist(_list):

...with...

from checks import checklist

Blocks in regex are delineated by parenthesis (which are not preceded by a "\")

(^.*import ) finds "from checks import " and loads it to $1 (eclipse starts counting at 1)

(.*) find the next "everything" until the next encountered "(" and loads it to $2. $2 stops at the "(" because of the next part (see next line below)

(\(.*\):) says "at the first encountered "(" after starting block $2...stop block $2 and start $3. $3 gets loaded with the "('any text'):" or, in the example, the "(_list):"

Then in the replace, just put the $1$2 to replace all three blocks with just the first two.

I don't think there would be an automatic way. You might also want to add a page number to the appendix correctly. Assuming that you already have your pdf document of several pages, you'll have to extract each page first of your pdf document using Adobe Acrobat Professional for instance and save each of them as a separate pdf file. Then you'll have to include each of the the pdf documents as images on an each page basis (1 each page) and use newpage between each page e,g,

\appendix
\section{Quiz 1}\label{sec:Quiz}
\begin{figure}[htp] \centering{
\includegraphics[scale=0.82]{quizz.pdf}}
\caption{Experiment 1}
\end{figure}  

\newpage
\section{Sample paper}\label{sec:Sample}
\begin{figure}[htp] \centering{
\includegraphics[scale=0.75]{sampaper.pdf}}
\caption{Experiment 2}
\end{figure}

Now each page will appear with 1 pdf image per page and you'll have a correct page number at the bottom. As shown in my example, you'll have to play a bit with the scale factor for each image to get it in the right size that will fit on a single page. Hope that helps...

states.split() will return

['Alaska',
 'Alabama',
 'Arkansas',
 'American',
 'Samoa',
 'Arizona',
 'California',
 'Colorado']

If you need one random from them, then you have to use the random module:

import random

states = "... ..."

random_state = random.choice(states.split())

1.) Create an arraylist of appropriate type, in this case i.e String

2.) Create a JSONObject while passing your string to JSONObject constructor as input

• As JSONObject notation is represented by braces i.e {}
• Where as JSONArray notation is represented by square brackets i.e []

3.) Retrieve JSONArray from JSONObject (created at 2nd step) using "interests" as index.

4.) Traverse JASONArray using loops upto the length of array provided by length() function

5.) Retrieve your JSONObjects from JSONArray using getJSONObject(index) function

6.) Fetch the data from JSONObject using index '"interestKey"'.

Note : JSON parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes (") like this

`"{"key":"value"}"`

should be like this

`"{\"key\":\"value\"}"`

so you can use JSONParser to achieve escaped sequence format for safety as

JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);

Code :

JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";

JSONObject jsonObj = (JSONObject) parser.parse(response);

or

JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> interestList = new ArrayList<String>();

JSONArray jsonArray = jsonObj.getJSONArray("interests");

for(int i = 0 ; i < jsonArray.length() ; i++){
    interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}

Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key so in those cases when you are not sure about the presence of value so use optString, optInt, optBoolean etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value

From docs

Get an optional string associated with a key. It returns the defaultValue if there is no such key.

 public String optString(String key, String defaultValue) {

  String missingKeyValue = json_data.optString("status","N/A");
  // note there is no such key as "status" in response
  // will return "N/A" if no key found 

or To get empty string i.e "" if no key found then simply use

  String missingKeyValue = json_data.optString("status");
  // will return "" if no key found where "" is an empty string

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

setAlpha(int) is deprecated as of API 16: Android 4.1

Maven always checks your local repository first, however,your dependency needs to be installed in your repo for maven to find it.

Run mvn install in your dependency module first, and then build your dependent module.

I would simply write each line to a file, since it's already in a CSV format:

write_file = "output.csv"
with open(write_file, "w") as output:
    for line in text:
        output.write(line + '\n')

I can't recall how to write lines with line-breaks at the moment, though :p

Also, you might like to take a look at this answer about write(), writelines(), and '\n'.

Django 3.0

here is link how to customize error views

here is link how to render a view

in the urls.py (the main one, in project folder), put:

handler404 = 'my_app_name.views.custom_page_not_found_view'
handler500 = 'my_app_name.views.custom_error_view'
handler403 = 'my_app_name.views.custom_permission_denied_view'
handler400 = 'my_app_name.views.custom_bad_request_view'

and in that app (my_app_name) put in the views.py:

def custom_page_not_found_view(request, exception):
    return render(request, "errors/404.html", {})

def custom_error_view(request, exception=None):
    return render(request, "errors/500.html", {})

def custom_permission_denied_view(request, exception=None):
    return render(request, "errors/403.html", {})

def custom_bad_request_view(request, exception=None):
    return render(request, "errors/400.html", {})

NOTE: error/404.html is the path if you place your files into the projects (not the apps) template foldertemplates/errors/404.html so please place the files where you want and write the right path.

NOTE 2: After page reload, if you still see the old template, change in settings.py DEBUG=True, save it, and then again to False (to restart the server and collect the new files).

This is much easier in Swift 3 and later using reduce:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.reduce("") { $0 + String(format: "%02x", $1) }

    DispatchQueue.global(qos: .background).async { 
        let url = URL(string: "https://example.com/myApp/apns.php")!

        var request = URLRequest(url: url)
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.httpMethod = "POST"
        request.httpBody = try! JSONSerialization.data(withJSONObject: [
            "token" : token, 
            "ios" : UIDevice.current.systemVersion,
            "languages" : Locale.preferredLanguages.joined(separator: ", ")
            ])

        URLSession.shared.dataTask(with: request).resume()
    }
}

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

If you are using the Sun JVM, and are interested in the internal memory usage of the application (how much out of the allocated memory your app is using) I prefer to turn on the JVMs built-in garbage collection logging. You simply add -verbose:gc to the startup command.

From the Sun documentation:

The command line argument -verbose:gc prints information at every collection. Note that the format of the -verbose:gc output is subject to change between releases of the J2SE platform. For example, here is output from a large server application:

[GC 325407K->83000K(776768K), 0.2300771 secs]
[GC 325816K->83372K(776768K), 0.2454258 secs]
[Full GC 267628K->83769K(776768K), 1.8479984 secs]

Here we see two minor collections and one major one. The numbers before and after the arrow

325407K->83000K (in the first line)

indicate the combined size of live objects before and after garbage collection, respectively. After minor collections the count includes objects that aren't necessarily alive but can't be reclaimed, either because they are directly alive, or because they are within or referenced from the tenured generation. The number in parenthesis

(776768K) (in the first line)

is the total available space, not counting the space in the permanent generation, which is the total heap minus one of the survivor spaces. The minor collection took about a quarter of a second.

0.2300771 secs (in the first line)

In general you put your translations in resource files, e.g. resources.resx.

Each specific culture has a different name, e.g. resources.nl.resx, resources.fr.resx, resources.de.resx, …

Now the most important part of a solution is to maintain your translations. In Visual Studio install the Microsoft MAT tool: Multilingual App Toolkit (MAT). Works with winforms, wpf, asp.net (core), uwp, …

In general, e.g. for a WPF solution, in the WPF project

• Install the Microsoft MAT extension for Visual Studio.
• In the Solution Explorer, navigate to your Project > Properties > AssemblyInfo.cs
• Add in AssemblyInfo.cs your default, neutral language (in my case English): [assembly: System.Resources.NeutralResourcesLanguage("en")]
• Select your project in Solution Explorer and in Visual Studio, from the top menu, click "Tools" > "Multilingual App Toolkit" > "Enable Selection", to enable MAT for the project.
  • Now Right mouse click on the project in Solution Explorer, select "Multilingual App Toolkit" > "Add translation languages…" and select the language that you want to add translations for. e.g. Dutch.

What you will see is that a new folder will be created, called "MultilingualResources" containing a ....nl.xlf file.

The only thing you now have to do is:

1. add your translation to your default resources.resx file (in my case English)
2. Translate by clicking the .xlf file (NOT the .resx file) as the .xlf files will generate/update the .resx files.

(the .xlf files should open with the "Multilingual Editor", if this is not the case, right mouse click on the .xlf file, select "Open With…" and select "Multilingual Editor".

Have fun! now you can also see what has not been translated, export translations in xlf to external translation companies, import them again, recycle translations from other projects etc...

More info:

• Using the Multilingual App Toolkit 4.0: https://docs.microsoft.com/windows/uwp/design/globalizing/use-mat

You could simply use CSS animated text generator. There are pre-created templates already

This workaround works most of the time. It uses eclipse's 'smart insert' features instead:

1. Control X to erase the selected block of text, and keep it for pasting.
2. Control+Shift Enter, to open a new line for editing above the one you are at.
3. You might want to adjust the tabbing position at this point. This is where tabbing will start, unless you are at the beginning of the line.
4. Control V to paste back the buffer.

Hope this helps until Shift+TAB is implemented in Eclipse.

In addition to Oleiade, see the spec on zero values:

When memory is allocated to store a value, either through a declaration or a call of make or new, and no explicit initialization is provided, the memory is given a default initialization. Each element of such a value is set to the zero value for its type: false for booleans, 0 for integers, 0.0 for floats, "" for strings, and nil for pointers, functions, interfaces, slices, channels, and maps. This initialization is done recursively, so for instance each element of an array of structs will have its fields zeroed if no value is specified.

As you can see, nil is not the zero value for every type but only for pointers, functions, interfaces, slices, channels and maps. This is the reason why config == nil is an error and &config == nil is not.

To check whether your struct is uninitialized you'd have to check every member for its respective zero value (e.g. host == "", port == 0, etc.) or have a private field which is set by an internal initialization method. Example:

type Config struct {
    Host string  
    Port float64
    setup bool
}

func NewConfig(host string, port float64) *Config {
    return &Config{host, port, true}
}

func (c *Config) Initialized() bool { return c != nil && c.setup }

Its all about data which you pass; has to properly formatted string. If you are passing empty data then data: {} will work. However with multiple parameters it has to be properly formatted e.g.

var dataParam = '{' + '"data1Variable": "' + data1Value+ '", "data2Variable": "' + data2Value+ '"' +  '}';

....

data : dataParam

...

Best way to understand is have error handler with proper message parameter, so as to know the detailed errors.

On Kotlin you can set width and height of any view directly using their virtual properties:

someView.layoutParams.width = 100
someView.layoutParams.height = 200

There is no such functionality but you can use a temporary file by File.createTempFile().

File temp = File.createTempFile(prefix, suffix);
// tell system to delete it when vm terminates.
temp.deleteOnExit();

In SQL, anything you evaluate / compute with NULL results into UNKNOWN

This is why SELECT * FROM MyTable WHERE MyColumn != NULL or SELECT * FROM MyTable WHERE MyColumn <> NULL gives you 0 results.

To provide a check for NULL values, isNull function is provided.

Moreover, you can use the IS operator as you used in the third query.

Hope this helps.

According to the article Chris Corio: Teach Your Apps To Play Nicely With Windows Vista User Account Control, MSDN Magazine, Jan. 2007, only ShellExecute checks the embedded manifest and prompts the user for elevation if needed, while CreateProcess and other APIs don't. Hope it helps.

In a multi-select option box, you can use $('#input1 :selected').length; to get the number of selected options. This can be useful to disable buttons if a certain minimum number of options aren't met.

function refreshButtons () {
    if ($('#input :selected').length == 0)
    {
        $('#submit').attr ('disabled', 'disabled');
    }
    else
    {
        $('#submit').removeAttr ('disabled');
    }
}

2. decide how your POSTed data will be transfered.

1 Certificates

By default:

• CURLOPT_SSL_VERIFYHOST == 2 which "checks the existence of a common name and also verify that it matches the hostname provided" and

• CURLOPT_VERIFYPEER == true which "verifies the peer's certificate".

So, all you have to do is:

const CAINFO = SERVER_ROOT . '/registry/cacert.pem';
...
\curl_setopt($ch, CURLOPT_CAINFO, self::CAINFO);

taken from a working class where SERVER_ROOT is a constant defined during application bootstraping like in a custom classloader, another class etc.

Forget things like \curl_setopt($handler, CURLOPT_SSL_VERIFYHOST, 0); or \curl_setopt($handler, CURLOPT_SSL_VERIFYPEER, 0);.

Find cacert.pem there as seen in this question.

2 POST modes

There are actually 2 modes when posting data:

• the data is transfered with Content-Type header set to multipart/form-data or,

• the data is a urlencoded string with application/x-www-form-urlencoded encoding.

In the first case you pass an array while in the second you pass a urlencoded string.

multipart/form-data ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

application/x-www-form-urlencoded ex.:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, \http_build_query($fields));

http_build_query:

Test it at your command line as

user@group:$ php -a
php > $fields = array('a' => 'sth', 'b' => 'else');
php > echo \http_build_query($fields);
a=sth&b=else

The other end of the POST request will define the appropriate mode of connection.

Checkout the files in https://github.com/PyCQA/pylint/tree/master/pylint/checkers. I haven't found a better way to obtain the error name from a message than either Ctrl + F-ing those files or using the GitHub search feature:

If the message is "No name ... in module ...", use the search:

No name %r in module %r repo:PyCQA/pylint/tree/master path:/pylint/checkers

Or, to get fewer results:

"No name %r in module %r" repo:PyCQA/pylint/tree/master path:/pylint/checkers

GitHub will show you:

"E0611": (
    "No name %r in module %r",
    "no-name-in-module",
    "Used when a name cannot be found in a module.",

You can then do:

1)TempData

Allows you to store data that will survive for a redirect. Internally it uses the Session as backing store, after the redirect is made the data is automatically evicted. The pattern is the following:

public ActionResult Foo()
{
    // store something into the tempdata that will be available during a single redirect
    TempData["foo"] = "bar";

    // you should always redirect if you store something into TempData to
    // a controller action that will consume this data
    return RedirectToAction("bar");
}

public ActionResult Bar()
{
    var foo = TempData["foo"];
    ...
}

2)ViewBag, ViewData

Allows you to store data in a controller action that will be used in the corresponding view. This assumes that the action returns a view and doesn't redirect. Lives only during the current request.

The pattern is the following:

public ActionResult Foo()
{
    ViewBag.Foo = "bar";
    return View();
}

and in the view:

@ViewBag.Foo

or with ViewData:

public ActionResult Foo()
{
    ViewData["Foo"] = "bar";
    return View();
}

and in the view:

@ViewData["Foo"]

ViewBag is just a dynamic wrapper around ViewData and exists only in ASP.NET MVC 3.

This being said, none of those two constructs should ever be used. You should use view models and strongly typed views. So the correct pattern is the following:

View model:

public class MyViewModel
{
    public string Foo { get; set; }
}

Action:

public Action Foo()
{
    var model = new MyViewModel { Foo = "bar" };
    return View(model);
}

Strongly typed view:

@model MyViewModel
@Model.Foo

After this brief introduction let's answer your question:

My requirement is I want to set a value in a controller one, that controller will redirect to ControllerTwo and Controller2 will render the View.

public class OneController: Controller
{
    public ActionResult Index()
    {
        TempData["foo"] = "bar";
        return RedirectToAction("index", "two");
    }
}

public class TwoController: Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            Foo = TempData["foo"] as string
        };
        return View(model);
    }
}

and the corresponding view (~/Views/Two/Index.cshtml):

@model MyViewModel
@Html.DisplayFor(x => x.Foo)

There are drawbacks of using TempData as well: if the user hits F5 on the target page the data will be lost.

Personally I don't use TempData neither. It's because internally it uses Session and I disable session in my applications. I prefer a more RESTful way to achieve this. Which is: in the first controller action that performs the redirect store the object in your data store and user the generated unique id when redirecting. Then on the target action use this id to fetch back the initially stored object:

public class OneController: Controller
{
    public ActionResult Index()
    {
        var id = Repository.SaveData("foo");
        return RedirectToAction("index", "two", new { id = id });
    }
}

public class TwoController: Controller
{
    public ActionResult Index(string id)
    {
        var model = new MyViewModel
        {
            Foo = Repository.GetData(id)
        };
        return View(model);
    }
}

The view stays the same.

var result = (35.8 / 100) * 10;

This worked for me

I ran into a similar issue when building a custom pagination for a site I am working on.

The global variable I created in functions.php was defined and set to 0. I could output this value in my javascript no problem using the method @Karsten outlined above. The issue was with updating the global variable that I initially set to 0 inside the PHP file.

Here is my workaround (hacky? I know!) but after struggling for an hour on a tight deadline the following works:

Inside archive-episodes.php:

<script>
    // We define the variable and update it in a php
    // function defined in functions.php
    var totalPageCount; 
</script>

Inside functions.php

<?php
    $totalPageCount = WP_Query->max_num_pages; // In my testing scenario this number is 8.
    echo '<script>totalPageCount = $totalPageCount;</script>';
?>

To keep it simple, I was outputting the totalPageCount variable in an $ajax.success callback via alert.

$.ajax({
        url: ajaxurl,
        type: 'POST',
        data: {"action": "infinite_scroll", "page_no": pageNumber, "posts_per_page": numResults},
        beforeSend: function() {
            $(".ajaxLoading").show();
        },
        success: function(data) {
                            //alert("DONE LOADING EPISODES");
            $(".ajaxLoading").hide();

            var $container = $("#episode-container");

            if(firstRun) {
                $container.prepend(data);
                initMasonry($container);
                ieMasonryFix();
                initSearch();
            } else {
                var $newItems = $(data);
                $container.append( $newItems ).isotope( 'appended', $newItems );
            }
            firstRun = false;

            addHoverState();                            
            smartResize();

            alert(totalEpiPageCount); // THIS OUTPUTS THE CORRECT PAGE TOTAL
        }

Be it as it may, I hope this helps others! If anyone has a "less-hacky" version or best-practise example I'm all ears.

The date function would be defined something like this:

function date($format, $timestamp = null)
{
    if ($timestamp === null) {
        $timestamp = time();
    }

    // Format the timestamp according to $format
}

Usually, you would put the default value like this:

function foo($required, $optional = 42)
{
    // This function can be passed one or more arguments
}

However, only literals are valid default arguments, which is why I used null as default argument in the first example, not $timestamp = time(), and combined it with a null check. Literals include arrays (array() or []), booleans, numbers, strings, and null.

This worked for me.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    btnSendSMS.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            sendSMS("5556", "Hi You got a message!");
           /*here i can send message to emulator 5556. In Real device 
            *you can change number*/
        }
    });
}

//Sends an SMS message to another device

private void sendSMS(String phoneNumber, String message) {
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);
}

You can add this line in AndroidManifest.xml

<uses-permission android:name="android.permission.SEND_SMS"/>

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using

The input type="file" field is very tricky because it behaves differently on every browser, it can't be styled, or can be styled a little, depending on the browser again; and it is difficult to resize (depending on the browser again, it may have a minimal size that can't be overwritten).

There are workarounds though. The best one is in my opinion this one (the result is here).

None of these answers worked for me.

I had to remove all deployed java web app:

• Windows/Show View/Other...
• Go the the Server folder and select "Servers"
• Right-click on the J2EE Preview at localhost
• Click to Add and Remove... Click Remove all

Then run the project on the server

The Error is gone!

You will have to stop the server before deploying another project because it will not be found by the server. Otherwise you will get a 404 error

For @atari2600, this is what the answer would look like using ToLookup in lambda syntax:

var x = listOfCustomObjects
    .GroupBy(o => o.PropertyName)
    .ToLookup(customObject => customObject);

Basically, it takes the IGrouping and materializes it for you into a dictionary of lists, with the values of PropertyName as the key.

If you're using a std::string, call length():

std::string str = "hello";
std::cout << str << ":" << str.length();
// Outputs "hello:5"

If you're using a c-string, call strlen().

const char *str = "hello";
std::cout << str << ":" << strlen(str);
// Outputs "hello:5"

Or, if you happen to like using Pascal-style strings (or f***** strings as Joel Spolsky likes to call them when they have a trailing NULL), just dereference the first character.

const char *str = "\005hello";
std::cout << str + 1 << ":" << *str;
// Outputs "hello:5"

Quite amazing how all answers talk about IIS, as if that were the only web server that mattered. Even back in 2010 when the question was asked, Apache had between 60% and 70% of the market share. Anyway,

• The HTTP protocol does not specify a limit.
• The POST method allows sending far more data than the GET method, which is limited by the URL length - about 2KB.
• The maximum POST request body size is configured on the HTTP server and typically ranges from
  1MB to 2GB
• The HTTP client (browser or other user agent) can have its own limitations. Therefore, the maximum POST body request size is min(serverMaximumSize, clientMaximumSize).

Here are the POST body sizes for some of the more popular HTTP servers:

• Ngix (largest web server market share as of April 2019) - default 1MB, no practical maximum (2**63)
• Apache - maximum 2GB, no default documented
• IIS - default 28.6MB for the request length, 2048 bytes for the query string; maximum undocumented
• InfluxDB - default ~25MB, maximum undocumented

Surprisingly this question doesn't have a definitive documented answer. Perhaps another data point would provide value to others looking for an answer. On my systems running CentOS (6.8,7.3) and Java 8 (build 1.8.0_60-b27, 64-Bit Server):

default memory is 1/4 of physical memory, not limited by 1GB.

Also, -XX:+PrintFlagsFinal prints to STDERR so command to determine current default memory presented by others above should be tweaked to the following:

java -XX:+PrintFlagsFinal 2>&1 | grep MaxHeapSize

The following is returned on system with 64GB of physical RAM:

uintx MaxHeapSize                                  := 16873684992      {product}

Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when and verify.

Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T> and expose a method matches(T) that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.

/* Mockito */  verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));

Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T where Hamcrest matcher methods return Matcher objects (of type Matcher<T>).

Mockito matchers are invoked through static methods such as eq, any, gt, and startsWith on org.mockito.Matchers and org.mockito.AdditionalMatchers. There are also adapters, which have changed across Mockito versions:

• For Mockito 1.x, Matchers featured some calls (such as intThat or argThat) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T> extended org.hamcrest.Matcher<T>, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.
• For Mockito 2.0+, Mockito no longer has a direct dependency on Hamcrest. Matchers calls phrased as intThat or argThat wrap ArgumentMatcher<T> objects that no longer implement org.hamcrest.Matcher<T> but are used in similar ways. Hamcrest adapters such as argThat and intThat are still available, but have moved to MockitoHamcrest instead.

Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:

/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));

In the above statement: foo.setPowerLevel is a method that accepts an int. is(greaterThan(9000)) returns a Matcher<Integer>, which wouldn't work as a setPowerLevel argument. The Mockito matcher intThat wraps that Hamcrest-style Matcher and returns an int so it can appear as an argument; Mockito matchers like gt(9000) would wrap that entire expression into a single call, as in the first line of example code.

What matchers do/return

when(foo.quux(3, 5)).thenReturn(true);

When not using argument matchers, Mockito records your argument values and compares them with their equals methods.

when(foo.quux(eq(3), eq(5))).thenReturn(true);    // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different

When you call a matcher like any or gt (greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture() it stores a matcher that saves its argument instead for later inspection.

Matchers return dummy values such as zero, empty collections, or null. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt() or any(Integer.class) or an empty List<String> for anyListOf(String.class). Because of type erasure, though, Mockito lacks type information to return any value but null for any() or argThat(...), which can cause a NullPointerException if trying to "auto-unbox" a null primitive value.

Matchers like eq and gt take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.

Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt()) or thenReturn(any(Foo.class)) in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.

Implementation details

Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.

Most matcher calls only add to this stack, with an exception for matchers like and, or, and not. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:

when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6]      [5]  [1]       [4] [2]     [3]

This will:

1. Add anyInt() to the stack.
2. Add gt(10) to the stack.
3. Add lt(20) to the stack.
4. Remove gt(10) and lt(20) and add and(gt(10), lt(20)).
5. Call foo.quux(0, 0), which (unless otherwise stubbed) returns the default value false. Internally Mockito marks quux(int, int) as the most recent call.
6. Call when(false), which discards its argument and prepares to stub method quux(int, int) identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any() matcher for its first argument and and(gt(10), lt(20)) for its second argument and clears the stack.

This demonstrates a few rules:

• Mockito can't tell the difference between quux(anyInt(), 0) and quux(0, anyInt()). They both look like a call to quux(0, 0) with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.

• Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.

  int between10And20 = and(gt(10), lt(20));
  /* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
  // Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
  
  public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
  /* OK */  when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
  // The helper method calls the matcher methods in the right order.
  

• The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when or verify, but Mockito can't check that automatically. You can check manually with Mockito.validateMockitoUsage().

• In a call to when, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values). doReturn and doAnswer (etc) do not invoke the actual method and are often a useful alternative.

• If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq matcher), Mockito would check the stack length against that call instead, and likely fail.

• If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.

Common problems

• InvalidUseOfMatchersException:

  • Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when or verify call. Matchers should never be used as stubbed return values or fields/variables.

  • Check that you're not calling a mock as a part of providing a matcher argument.

  • Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.

• NullPointerException with primitive arguments: (Integer) any() returns null while any(Integer.class) returns 0; this can cause a NullPointerException if you're expecting an int instead of an Integer. In any case, prefer anyInt(), which will return zero and also skip the auto-boxing step.

• NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz) will actually call foo.bar(null), which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any()) skips the stubbed behavior.

General troubleshooting

• Use MockitoJUnitRunner, or explicitly call validateMockitoUsage in your tearDown or @After method (which the runner would do for you automatically). This will help determine whether you've misused matchers.

• For debugging purposes, add calls to validateMockitoUsage in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

The JDK (JAVA_HOME) used to launch Eclipse is not necessarily the one used to compiled your project.

To see what JRE you can select for your project, check the preferences:

General ? Java Installed JRE

By default, if you have not added any JRE, the only one declared will be the one used to launched Eclipse (which can be defined in your eclipse.ini).

You can add any other JRE you want, including one compatible with your project.

After that, you will need to check in your project properties (or in the general preferences) what JRE is used, with what compliance level:

You can use Xtend (Infix Operators and Operator Overloading) to overload operators and 'stay' on Java

ch=str(ch,'utf-8')
print(ch)

I had the same warning using the raster package.

> my_mask[my_mask[] != 1] <- NA
Error: cannot allocate vector of size 5.4 Gb

The solution is really simple and consist in increasing the storage capacity of R, here the code line:

##To know the current storage capacity
> memory.limit()
[1] 8103
## To increase the storage capacity
> memory.limit(size=56000)
[1] 56000    
## I did this to increase my storage capacity to 7GB

Hopefully, this will help you to solve the problem Cheers

It is considered bad practice to invoke the actual generator (e.g. via make) if using CMake. It is highly recommended to do it like this:

1. Configure phase:

   cmake -Hfoo -B_builds/foo/debug -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=/usr
   

2. Build and Install phases

   cmake --build _builds/foo/debug --config Debug --target install
   

When following this approach, the generator can be easily switched (e.g. -GNinja for Ninja) without having to remember any generator-specific commands.

var setVariable = (typeof localStorage.getItem('value') !== 'undefined' && localStorage.getItem('value')) || 0;

I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).

I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.

I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.

Hope this helps!

You can prevent all pointer events to be sent to the input by using the CSS property : pointer-events:none It will kind of add a layer on top of the element that will prevent you to click in it ... You can also add a cursor:text to the parent element to give back the text cursor style to the input ...

Usefull, for example, when you can't modify the JS/HTML of a module.. and you can just customize it by css.

JSFIDDLE

Do you have access to your database, if so just open it up and look up the column and use an SQL call to retrieve the needed.

A short example on a form to retrieve data from a database table:

Form contain only a GataGridView named DataGrid

Database name: DB.mdf

Table name: DBtable

Column names in table: Name as varchar(50), Age as int, Gender as bit.

Private Sub DatabaseTest_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    Public ConString As String = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\{username}\documents\visual studio 2010\Projects\Userapplication prototype v1.0\Userapplication prototype v1.0\Database\DB.mdf;" & "Integrated Security=True;User Instance=True"
    Dim conn As New SqlClient.SqlConnection
    Dim cmd As New SqlClient.SqlCommand
    Dim da As New SqlClient.SqlDataAdapter
    Dim dt As New DataTable
    Dim sSQL As String = String.Empty
    Try
        conn = New SqlClient.SqlConnection(ConString)
        conn.Open() 'connects to the database
        cmd.Connection = conn
        cmd.CommandType = CommandType.Text
        sSQL = "SELECT * FROM DBtable" 'Sql to be executed
        cmd.CommandText = sSQL 'makes the string a command
        da.SelectCommand = cmd 'puts the command into the sqlDataAdapter
        da.Fill(dt) 'populates the dataTable by performing the command above
        Me.DataGrid.DataSource = dt 'Updates the grid using the populated dataTable

        'the following is only if any errors happen:
        If dt.Rows.Count = 0 Then
            MsgBox("No record found!")
        End If
    Catch ex As Exception
        MsgBox(ErrorToString)
    Finally
        conn.Close() 'closes the connection again so it can be accessed by other users or programs
    End Try
End Sub

This will fetch all the rows and columns from your database table for review.
If you want to only fetch the names just change the sql call with: "SELECT Name FROM DBtable" this way the DataGridView will only show the column names.

I'm only a rookie but i would strongly advise to get rid of theses auto generate wizards. Using SQL you have full access to your database and what happens.
Also one last thing, if your database doesn't use SQLClient just change it to OleDB.

Example: "Dim conn As New SqlClient.SqlConnection" becomes: Dim conn As New OleDb.OleDbConnection

Try to connect to repositroy with url: http://github.com/<user>/<project>.git (http except https)

In your case you should clone like this:

git clone http://github.com/<user>/<project>.git

This code prints out all the directories and files in my documents directory:

Some modification of your function:

func listFilesFromDocumentsFolder() -> [String]
{
    let dirs = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.allDomainsMask, true)
    if dirs != [] {
        let dir = dirs[0]
        let fileList = try! FileManager.default.contentsOfDirectory(atPath: dir)
        return fileList
    }else{
        let fileList = [""]
        return fileList
    }
}

Which gets called by:

    let fileManager:FileManager = FileManager.default
    let fileList = listFilesFromDocumentsFolder()

    let count = fileList.count

    for i in 0..<count
    {
        if fileManager.fileExists(atPath: fileList[i]) != true
        {
            print("File is \(fileList[i])")
        }
    }

let is used to declare a constant value - you won't change it after giving it an initial value.
var is used to declare a variable value - you could change its value as you wish.

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

Try the maven-exec-plugin. From there:

mvn exec:java -Dexec.mainClass="com.example.Main"

This will run your class in the JVM. You can use -Dexec.args="arg0 arg1" to pass arguments.

If you're on Windows, apply quotes for exec.mainClass and exec.args:

mvn exec:java -D"exec.mainClass"="com.example.Main"

If you're doing this regularly, you can add the parameters into the pom.xml as well:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.2.1</version>
  <executions>
    <execution>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>com.example.Main</mainClass>
    <arguments>
      <argument>foo</argument>
      <argument>bar</argument>
    </arguments>
  </configuration>
</plugin>

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

Guys in some PC's this issue is caused by antivirus programs AFTER upgrading to the latest android studio and gradle version. In my case I tore my system apart troubleshooting everything only to find out that Commodo Internet security was responsible for not letting the gradle daemon run.

After safelisting the process everything runs smoothly. PLEASE NOTE that everything was OK before updating. The issue came up only after the update without changing anything in the antivirus/firewall program.

@Michael Yagudaev 's answer works for me.

But the original answer did not chain the wrapped promise with .catch() to handle reject handling, here is my improvement on top of @Michael Yagudaev's answer:

const makeCancelablePromise = promise => {
  let hasCanceled = false;
  const wrappedPromise = new Promise((resolve, reject) => {
    promise
      .then(val => (hasCanceled ? reject({ isCanceled: true }) : resolve(val)))
      .catch(
        error => (hasCanceled ? reject({ isCanceled: true }) : reject(error))
      );
  });

  return {
    promise: wrappedPromise,
    cancel() {
      hasCanceled = true;
    }
  };
};

// Example Usage:
const cancelablePromise = makeCancelable(
  new Promise((rs, rj) => {
    /*do something*/
  })
);
cancelablePromise.promise.then(() => console.log('resolved')).catch(err => {
  if (err.isCanceled) {
    console.log('Wrapped promise canceled');
    return;
  }
  console.log('Promise was not canceled but rejected due to errors: ', err);
});
cancelablePromise.cancel();

I tried putting the file in the wwwroot. So when accessing the page in Chrome, this is the address localhost/yourpage.xml.

You can set a reference to the Scripting.Runtime library and then use the FileSystemObject. It has a DeleteFile method and a FileExists method.

See the MSDN article here.

The problem seems to happen when you have an alias the same name as the objects property. Hibernate seems to pick up the alias and use it in the sql. I found this documented here and here, and I believe it to be a bug in Hibernate, although I am not sure that the Hibernate team agrees.

Either way, I have found a simple work around that works in my case. Your mileage may vary. The details are below, I tried to simplify the code for this sample so I apologize for any errors or typo's:

Criteria criteria = session.createCriteria(MyClass.class)
    .setProjection(Projections.projectionList()
        .add(Projections.property("sectionHeader"), "sectionHeader")
        .add(Projections.property("subSectionHeader"), "subSectionHeader")
        .add(Projections.property("sectionNumber"), "sectionNumber"))
    .add(Restrictions.ilike("sectionHeader", sectionHeaderVar)) // <- Problem!
    .setResultTransformer(Transformers.aliasToBean(MyDTO.class));

Would produce this sql:

select
    this_.SECTION_HEADER as y1_,
    this_.SUB_SECTION_HEADER as y2_,
    this_.SECTION_NUMBER as y3_,
from
    MY_TABLE this_ 
where
    ( lower(y1_) like ? ) 

Which was causing an error: java.sql.SQLException: ORA-00904: "Y1_": invalid identifier

But, when I changed my restriction to use "this", like so:

Criteria criteria = session.createCriteria(MyClass.class)
    .setProjection(Projections.projectionList()
        .add(Projections.property("sectionHeader"), "sectionHeader")
        .add(Projections.property("subSectionHeader"), "subSectionHeader")
        .add(Projections.property("sectionNumber"), "sectionNumber"))
    .add(Restrictions.ilike("this.sectionHeader", sectionHeaderVar)) // <- Problem Solved!
    .setResultTransformer(Transformers.aliasToBean(MyDTO.class));

It produced the following sql and my problem was solved.

select
    this_.SECTION_HEADER as y1_,
    this_.SUB_SECTION_HEADER as y2_,
    this_.SECTION_NUMBER as y3_,
from
    MY_TABLE this_ 
where
    ( lower(this_.SECTION_HEADER) like ? ) 

Thats, it! A pretty simple fix to a painful problem. I don't know how this fix would translate to the query by example problem, but it may get you closer.

UPDATE - Even less wordy version

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5'),
       ('val1', 'val2', 'val3', 'val4', 'val5')

The following also works for DB2 and is slightly less wordy

INSERT INTO tableName (col1, col2, col3, col4, col5) 
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5') UNION ALL
VALUES ('val1', 'val2', 'val3', 'val4', 'val5')

Just change all port numbers to new of any working series.. . Don't change application host .config ...

Since Redis 2.6, lua is supported, you can get number of wildcard keys like this

eval "return #redis.call('keys', 'prefix-*')" 0

see eval command

Depending on the situation, it is often helpful to make the image a background image of a div with CSS.

<div id='my-image'></div>

Then in CSS:

#my-image {
    background-image: url('/img/foo.png');
    width: ???px;
    height: ???px;
}

See this JSFiddle for a live example with a button and a different sizing option.

You can also map the share to a local drive as follows:

net use X: "\\servername\share" /user:morgan password

I was checking how ax.axvline does work, and I've written a small function that resembles part of its idea:

import matplotlib.pyplot as plt
import matplotlib.lines as mlines

def newline(p1, p2):
    ax = plt.gca()
    xmin, xmax = ax.get_xbound()

    if(p2[0] == p1[0]):
        xmin = xmax = p1[0]
        ymin, ymax = ax.get_ybound()
    else:
        ymax = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmax-p1[0])
        ymin = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmin-p1[0])

    l = mlines.Line2D([xmin,xmax], [ymin,ymax])
    ax.add_line(l)
    return l

So, if you run the following code you will realize how does it work. The line will span the full range of your plot (independently on how big it is), and the creation of the line doesn't rely on any data point within the axis, but only in two fixed points that you need to specify.

import numpy as np
x = np.linspace(0,10)
y = x**2

p1 = [1,20]
p2 = [6,70]

plt.plot(x, y)
newline(p1,p2)
plt.show()

Change the code to:

public abstract class clsAbstractTable {
  protected String TAG;
  public abstract void init();
}

public class clsContactGroups extends clsAbstractTable {
  public String doSomething() {
    return TAG + "<something else>";
  }
}

That way, all of the classes who inherit this class will have this variable. You can do 200 subclasses and still each one of them will have this variable.

Side note: do not use CAPS as variable name; common wisdom is that all caps identifiers refer to constants, i.e. non-changeable pieces of data.

It can't take a file handle. The install_requires argument can only be a string or a list of strings.

You can, of course, read your file in the setup script and pass it as a list of strings to install_requires.

import os
from setuptools import setup

with open('requirements.txt') as f:
    required = f.read().splitlines()

setup(...
install_requires=required,
...)

ES7 Proposal

Warning: Unfortunately I believe most popular platforms have dropped support for comprehensions. See below for the well-supported ES6 method

You can always use something like:

[for (i of Array(7).keys()) i*i];

Running this code on Firefox:

[ 0, 1, 4, 9, 16, 25, 36 ]

This works on Firefox (it was a proposed ES7 feature), but it has been dropped from the spec. IIRC, Babel 5 with "experimental" enabled supports this.

This is your best bet as array-comprehension are used for just this purpose. You can even write a range function to go along with this:

var range = (u, l = 0) => [ for( i of Array(u - l).keys() ) i + l ]

Then you can do:

[for (i of range(5)) i*i] // 0, 1, 4, 9, 16, 25
[for (i of range(5,3)) i*i] // 9, 16, 25

ES6

A nice way to do this any of:

[...Array(7).keys()].map(i => i * i);
Array(7).fill().map((_,i) => i*i);
[...Array(7)].map((_,i) => i*i);

This will output:

[ 0, 1, 4, 9, 16, 25, 36 ]

I would not recommend utilizing the Grid system in this instance, as much as simply adding an increased padding for each <h2>. That being said, the way you would achieve this using col-*-offset-* would be as follows:

<div class="jumbotron">
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <h2>One</h2>
            </div>

            <div class="col-md-11 col-md-offset-1">
                <h2>Two</h2>
            </div>

            <div class="col-md-10 col-md-offset-2">
                <h2>Three</h2>
            </div>
        </div>
    </div>
</div>

Essentially the first line must span the entire row (so -12). The second line must be offset by 1 column, so you offset by 1 and give it a total width of 11 columns (11+1 = 12) and so forth. Your offset is always enough to ensure that the total column count equals 12.

This is not exactly a solution, but for opening new files this works great:

AdvancedNewFile

https://github.com/skuroda/Sublime-AdvancedNewFile

Command + Option + n to save a file in a new or existing directory.

So this would place your_file.html.erb in the existing views directory in a Rails app. If you needed a new directory -you would just type that as the path and then hit enter.

You can also Tab like in terminal to autocomplete for existing directories.

This does not give the sidebar navigation I am looking for, but at least helps with one significant need that is repeated often.

This code will print each individual number:

for myList in [[10,13,17],[3,5,1],[13,11,12]]:
    for item in myList:
        print(item)

Or for your specific use case:

((50 - List1[0][0]) + List1[0][1]) - List1[0][2]

Had to do something similar, hope this helps.

// Node packages for file system
var fs = require('fs');
var path = require('path');


var filePath = path.join(__dirname, 'PATH_TO_CSV');
// Read CSV
var f = fs.readFileSync(filePath, {encoding: 'utf-8'}, 
    function(err){console.log(err);});

// Split on row
f = f.split("\n");

// Get first row for column headers
headers = f.shift().split(",");

var json = [];    
f.forEach(function(d){
    // Loop through each row
    tmp = {}
    row = d.split(",")
    for(var i = 0; i < headers.length; i++){
        tmp[headers[i]] = row[i];
    }
    // Add object to list
    json.push(tmp);
});

var outPath = path.join(__dirname, 'PATH_TO_JSON');
// Convert object to string, write json to file
fs.writeFileSync(outPath, JSON.stringify(json), 'utf8', 
    function(err){console.log(err);});

SELECT id, user_id, video_name
FROM sa_created_videos
ORDER BY LENGTH(id) ASC, LENGTH(user_id) DESC

I know it's a several years old post and you may solve your problem with above solution. However, i just want to suggest using InverseProperty for someone who still need. At least you don't need to change anything in OnModelCreating.

The below code is un-tested.

public class Team
{
    [Key]
    public int TeamId { get; set;} 
    public string Name { get; set; }

    [InverseProperty("HomeTeam")]
    public virtual ICollection<Match> HomeMatches { get; set; }

    [InverseProperty("GuestTeam")]
    public virtual ICollection<Match> GuestMatches { get; set; }
}


public class Match
{
    [Key]
    public int MatchId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

You can read more about InverseProperty on MSDN: https://msdn.microsoft.com/en-us/data/jj591583?f=255&MSPPError=-2147217396#Relationships

I just encountered this same issue. Turned out the Project URL on the Web property sheet was malformed.

I had just removed a port number, forgot to delete the preceding colon and tried running with: http://localhost:/XYZ

Seems like lots of different issues result in this error message.

import matplotlib.pyplot as plt
plt.figure(figsize=(8,8))
plt.subplot(3,2,1)
plt.subplot(3,2,3)
plt.subplot(3,2,5)
plt.subplot(2,2,2)
plt.subplot(2,2,4)

The first code creates the first subplot in a layout that has 3 rows and 2 columns.

The three graphs in the first column denote the 3 rows. The second plot comes just below the first plot in the same column and so on.

The last two plots have arguments (2, 2) denoting that the second column has only two rows, the position parameters move row wise.

This functions should help you...

On my linux machine I use a script like this:

export IDEA_JDK=/opt/jdk14
/idea-IC/bin/idea.sh

Bit less elegant but can also do:

sl[len(sl)-1: len(sl)]

You can use MarkerWithLabel with SVG icons.

Update: The Google Maps Javascript API v3 now natively supports multiple characters in the MarkerLabel

proof of concept fiddle (you didn't provide your icon, so I made one up)

Note: there is an issue with labels on overlapping markers that is addressed by this fix, credit to robd who brought it up in the comments.

if you want to simply reload the parent window of child window: This line code below is enough for that.

opener.location.reload(); 

if you want to reload parent window with query string (request) with old or new values. Following code will do the work.

if (opener.location.href.indexOf('?') > 0) {
      var baseUrl = opener.location.href.substring(0, opener.location.href.indexOf('?'));
      opener.location.href = baseUrl + "?param1=abc&param2=123";
}
else {
      opener.location.href = opener.location.href + "?param1=abc&param2=123";
}

this opener.location.reload(); is not required in above example.

Alternatively (I'd say preferably), you can do it like this:

$(function () {
  $("div.class, div.secondclass").click(function(){
    //Doo something
  });
});

You can enter the long form command:

source ~/.bashrc

or you can use the shorter version of the command:

. ~/.bashrc

Web Site is what you deploy to an ASP.NET web server such as IIS. Just a bunch of files and folders. There’s nothing in a Web Site that ties you to Visual Studio (there’s no project file). Code-generation and compilation of web pages (such as .aspx, .ascx, .master) is done dynamically at runtime, and changes to these files are detected by the framework and automatically re-compiled. You can put code that you want to share between pages in the special App_Code folder, or you can pre-compile it and put the assembly in the Bin folder.

Web Application is a special Visual Studio project. The main difference with Web Sites is that when you build the project all the code files are compiled into a single assembly, which is placed in the bin directory. You don’t deploy code files to the web server. Instead of having a special folder for shared code files you can put them anywhere, just like you would do in class library. Because Web Applications contains files that are not meant to be deployed, such as project and code files, there’s a Publish command in Visual Studio to output a Web Site to a specified location.

App_Code vs Bin

Deploying shared code files is generally a bad idea, but that doesn’t mean you have to choose Web Application. You can have a Web Site that references a class library project that holds all the code for the Web Site. Web Applications is just a convenient way to do it.

This topic is specific to .aspx and .ascx files. This topic is decreasingly relevant in new application frameworks such as ASP.NET MVC and ASP.NET Web Pages which do not use codebehind files.

By having all code files compiled into a single assembly, including codebehind files of .aspx pages and .ascx controls, in Web Applications you have to re-build for every little change, and you cannot make live changes. This can be a real pain during development, since you have to keep re-building to see the changes, while with Web Sites changes are detected by the runtime and pages/controls are automatically recompiled.

Having the runtime manage the codebehind assemblies is less work for you, since you don't need to worry about giving pages/controls unique names, or organizing them into different namespaces.

I’m not saying deploying code files is always a good idea (specially not in the case of shared code files), but codebehind files should only contain code that perform UI specific tasks, wire-up events handlers, etc. Your application should be layered so that important code always end up in the Bin folder. If that is the case then deploying codebehind files shouldn't be considered harmful.

Another limitation of Web Applications is that you can only use the language of the project. In Web Sites you can have some pages in C#, some in VB, etc. No need for special Visual Studio support. That’s the beauty of the build provider extensibility.

Also, in Web Applications you don't get error detection in pages/controls as the compiler only compiles your codebehind classes and not the markup code (in MVC you can fix this using the MvcBuildViews option), which is compiled at runtime.

Visual Studio

Because Web Applications are Visual Studio projects you get some features not available in Web Sites. For instance, you can use build events to perform a variety of tasks, e.g. minify and/or combine Javascript files.

Another nice feature introduced in Visual Studio 2010 is Web.config transformation. This is also not available in Web Sites. Now works with Web Sites in VS 2013.

Building a Web Application is faster than building a Web Site, specially for large sites. This is mainly because Web Applications do not compile the markup code. In MVC if you set MvcBuildViews to true then it compiles the markup code and you get error detection, which is very useful. The down side is that every time you build the solution it builds the complete site, which can be slow and inefficient, specially if you are not editing the site. l find myself turning MvcBuildViews on and off (which requires a project unload). On the other hand, with Web Sites you can choose if you want to build the site as part of the solution or not. If you choose not to, then building the solution is very fast, and you can always click on the Web Site node and select Build, if you’ve made changes.

In an MVC Web Application project you have extra commands and dialogs for common tasks, like ‘Add View’, ‘Go To View’, ‘Add Controller’, etc. These are not available in an MVC Web Site.

If you use IIS Express as the development server, in Web Sites you can add virtual directories. This option is not available in Web Applications.

NuGet Package Restore does not work on Web Sites, you have to manually install packages listed on packages.config Package Restore now works with Web Sites starting NuGet 2.7

Here is my aproach of explaining te rules .style and #style are part of a matrix. that if not in the right order, they can override each other, or cause conflicts.

Here is the line up.

Matrix

#style 0,0,1,0 id

.style 0,1,0,0 class

if you want override these two you can use <style></style> witch has a matrix level or 1,0,0,0. And @media query's will override everything above... I am not sure about this but i think the ID selector # can only be used once in a page.

Your activity doesn't extend FragmentActivity from the support library, therefore the method is not present in the superclass

If you are targeting api 11 or above, you could use Activity.getFragmentManager instead.

I had got the same problem and this following code answered perfectly at this problem :

//Identificate separator
string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");
//Encoding
byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");

//Creation and specification of the request
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url); //sVal is id for the webService
wr.ContentType = "multipart/form-data; boundary=" + boundary;
wr.Method = "POST";
wr.KeepAlive = true;
wr.Credentials = System.Net.CredentialCache.DefaultCredentials;

string sAuthorization = "login:password";//AUTHENTIFICATION BEGIN
byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(sAuthorization);
string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);
wr.Headers.Add("Authorization: Basic " + returnValue); //AUTHENTIFICATION END
Stream rs = wr.GetRequestStream();


string formdataTemplate = "Content-Disposition: form-data; name=\"{0}\"\r\n\r\n{1}"; //For the POST's format

//Writting of the file
rs.Write(boundarybytes, 0, boundarybytes.Length);
byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(Server.MapPath("questions.pdf"));
rs.Write(formitembytes, 0, formitembytes.Length);

rs.Write(boundarybytes, 0, boundarybytes.Length);

string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n";
string header = string.Format(headerTemplate, "file", "questions.pdf", contentType);
byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
rs.Write(headerbytes, 0, headerbytes.Length);

FileStream fileStream = new FileStream(Server.MapPath("questions.pdf"), FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[4096];
int bytesRead = 0;
while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
{
    rs.Write(buffer, 0, bytesRead);
}
fileStream.Close();

byte[] trailer = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "--\r\n");
rs.Write(trailer, 0, trailer.Length);
rs.Close();
rs = null;

WebResponse wresp = null;
try
{
    //Get the response
    wresp = wr.GetResponse();
    Stream stream2 = wresp.GetResponseStream();
    StreamReader reader2 = new StreamReader(stream2);
    string responseData = reader2.ReadToEnd();
}
catch (Exception ex)
{
    string s = ex.Message;
}
finally
{
    if (wresp != null)
    {
        wresp.Close();
        wresp = null;
    }
    wr = null;
}

You need a web.config key to enable the pre 4.5 validation mode.

More Info on ValidationSettings:UnobtrusiveValidationMode:

Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

Type: UnobtrusiveValidationMode

Default value: None

Remarks: If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.

Example:

    <appSettings>
      <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
    </appSettings>

Create Learning Table:

CREATE TABLE "public"."learning" (
    "api_id" int4 DEFAULT nextval('share_api_api_id_seq'::regclass) NOT NULL,
    "title" varchar(255) COLLATE "default"
);

Insert Data Learning Table:

INSERT INTO "public"."learning" VALUES ('1', 'Google AI-01');
INSERT INTO "public"."learning" VALUES ('2', 'Google AI-02');
INSERT INTO "public"."learning" VALUES ('3', 'Google AI-01');

Step: 01

CREATE OR REPLACE FUNCTION get_all (pattern VARCHAR) RETURNS TABLE (
        learn_id INT,
        learn_title VARCHAR
) AS $$
BEGIN
    RETURN QUERY SELECT
        api_id,
        title
    FROM
        learning
    WHERE
        title = pattern ;
END ; $$ LANGUAGE 'plpgsql';

Step: 02

SELECT * FROM get_all('Google AI-01');

Step: 03

DROP FUNCTION get_all();

Demo:

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

This seems to be old post but still I wanted to share how this issue got fixed for me.

For users, who do not have admin access and when they open a command prompt, it runs under the user privilege. It means, you may have path like C:\Users\

so when trying C:\Users\XYZ>mvn --version , it actually search the JAVA_HOME path from user variables not system variables in Environment Variables.

So, In order to fix this, we need to create a environment variable for JAVA_HOME in user variables.

Hope, this helps someone.

This worked for me. It's simple for simple objects.

class Person {_x000D_
  constructor(firstName, lastName) {_x000D_
    this.firstName = firstName;_x000D_
    this.lastName = lastName;_x000D_
  }_x000D_
  getFullName() {_x000D_
    return this.lastName + " " + this.firstName;_x000D_
  }_x000D_
_x000D_
  static class(obj) {_x000D_
    return new Person(obj.firstName, obj.lastName);_x000D_
  }_x000D_
}_x000D_
_x000D_
var person1 = {_x000D_
  lastName: "Freeman",_x000D_
  firstName: "Gordon"_x000D_
};_x000D_
_x000D_
var gordon = Person.class(person1);_x000D_
console.log(gordon.getFullName());

I was also searching for a simple solution, and this is what I came up with, based on all other answers and my research. Basically, class Person has another constructor, called 'class' which works with a generic object of the same 'format' as Person. I hope this might help somebody as well.

As an improvement to Paul Egan's answer, this can be accomplished as follows:

sqlite3 database.db3 '.dump "table1" "table2"' | grep '^INSERT'

--or--

sqlite3 database.db3 '.dump "table1" "table2"' | grep -v '^CREATE'

The caveat, of course, is that you have to have grep installed.

Your test:

if (numberSet.length < 2) {
    return 0;
}

should be done before you allocate an array of that length in the below statement:

int[] differenceArray = new int[numberSet.length-1];

else you are already creating an array of size -1, when the numberSet.length = 0. That is quite odd. So, move your if statement as the first statement in your method.

Simple, ready-to-use and not obsolete solution:

function copyToClipboard(elementIdToCopy, elementIdToNotifyOutcome) {
    const contentToCopy = document.getElementById(elementIdToCopy).innerHTML;
    const elementToNotifyOutcome = document.getElementById(elementIdToNotifyOutcome);

    navigator.clipboard.writeText(contentToCopy).then(function() {
        elementToNotifyOutcome.classList.add('success');
        elementToNotifyOutcome.innerHTML = 'Copied!';
    }, function() {
        elementToNotifyOutcome.classList.add('failure');
        elementToNotifyOutcome.innerHTML = 'Sorry, did not work.';
    });
}

You could arrange to find all the files, remove the file names, leaving you a line containing just the directory name for each file, and then count the number of times each directory appears:

find . -type f |
sed 's%/[^/]*$%%' |
sort |
uniq -c

The only gotcha in this is if you have any file names or directory names containing a newline character, which is fairly unlikely. If you really have to worry about newlines in file names or directory names, I suggest you find them, and fix them so they don't contain newlines (and quietly persuade the guilty party of the error of their ways).

If you're interested in the count of the files in each sub-directory of the current directory, counting any files in any sub-directories along with the files in the immediate sub-directory, then I'd adapt the sed command to print only the top-level directory:

find . -type f |
sed -e 's%^\(\./[^/]*/\).*$%\1%' -e 's%^\.\/[^/]*$%./%' |
sort |
uniq -c

The first pattern captures the start of the name, the dot, the slash, the name up to the next slash and the slash, and replaces the line with just the first part, so:

./dir1/dir2/file1

is replaced by

./dir1/

The second replace captures the files directly in the current directory; they don't have a slash at the end, and those are replace by ./. The sort and count then works on just the number of names.

Swift 4

In swift 4 String conforms to Collection. Instead of substring, we should now use a subscript. So if you want to cut out only the word "play" from "Hello, playground", you could do it like this:

var str = "Hello, playground"
let start = str.index(str.startIndex, offsetBy: 7)
let end = str.index(str.endIndex, offsetBy: -6)
let result = str[start..<end] // The result is of type Substring

It is interesting to know, that doing so will give you a Substring instead of a String. This is fast and efficient as Substring shares its storage with the original String. However sharing memory this way can also easily lead to memory leaks.

This is why you should copy the result into a new String, once you want to clean up the original String. You can do this using the normal constructor:

let newString = String(result)

You can find more information on the new Substring class in the [Apple documentation].1

So, if you for example get a Range as the result of an NSRegularExpression, you could use the following extension:

extension String {

    subscript(_ range: NSRange) -> String {
        let start = self.index(self.startIndex, offsetBy: range.lowerBound)
        let end = self.index(self.startIndex, offsetBy: range.upperBound)
        let subString = self[start..<end]
        return String(subString)
    }

}

In SQL 2005:

select object_name(object_id), name
from sys.columns
where is_identity = 1

As it is 2015, and deprecation of mysql_* functionality, this is a PDO-only visualization.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    // End Vault

    $b='</br>';
    try {
        $theCategory="fruit";   // value from user, hard-coded here to get one in

        $dbh = new PDO("mysql:host=$host;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        // prepared statement with named placeholders
        $stmt = $dbh->prepare("select id,foodName from foods where category=:theCat and perishable=1");
        $stmt->bindParam(':theCat', $theCategory, PDO::PARAM_STR,20);
        $stmt->execute();
        echo "rowCount() returns: ".$stmt->rowCount().$b;   // See comments below from the Manual, varies from driver to driver

        $stmt = $dbh->prepare("select count(*) as theCount from foods where category=:theCat and perishable=1");
        $stmt->bindParam(':theCat', $theCategory, PDO::PARAM_STR,20);
        $stmt->execute();
        $row=$stmt->fetch();    // fetches just one row, which is all we expect
        echo "count(*) returns: ".$row['theCount'].$b;

        $stmt = null;
        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Schema for testing

create table foods
(   id int auto_increment primary key,
    foodName varchar(100) not null,
    category varchar(20) not null,
    perishable int not null
);
insert foods (foodName,category,perishable) values 
('kiwi','fruit',1),('ground hamburger','meat',1),
('canned pears','fruit',0),('concord grapes','fruit',1);

For my implementation, I get the output of 2 for both echos above. The purpose of the above 2 strategies is to determine if your driver implementation emits the rowCount, and if not, to seek a fall-back strategy.

From the Manual on PDOStatement::rowCount:

PDOStatement::rowCount() returns the number of rows affected by a DELETE, INSERT, or UPDATE statement.

For most databases, PDOStatement::rowCount() does not return the number of rows affected by a SELECT statement. Instead, use PDO::query() to issue a SELECT COUNT(*) statement with the same predicates as your intended SELECT statement, then use PDOStatement::fetchColumn() to retrieve the number of rows that will be returned. Your application can then perform the correct action.

lines.map(&:strip).join(" ")

This is how session state works in ASP.NET and ASP.NET MVC:

ASP.NET Session State Overview

Basically, you do this to store a value in the Session object:

Session["FirstName"] = FirstNameTextBox.Text;

To retrieve the value:

var firstName = Session["FirstName"];

example dom onchange usage:

<script type="text/javascript">

    function onAppSelection(selectBox) {
        // clear selection
        for(var i=0;i<=selectBox.length;i++) {
          var selectedNode  = selectBox.options[i];
             if(selectedNode!=null) {
                  selectedNode.removeAttribute("id");
                  selectedNode.removeAttribute("selected");
            }
        } 
        // assign  id and selected
        var selectedNode = selectBox.options[selectBox.selectedIndex];

            selectedNode.setAttribute("selected","");
        }
     }

</script>

A simple code for this will be

time = time.split(':');// here the time is like "16:14"
let meridiemTime = time[0] >= 12 && (time[0]-12 || 12) + ':' + time[1] + ' PM' || (Number(time[0]) || 12) + ':' + time[1] + ' AM';

You can adjust according to your time format

SELECT DATEDIFF (MyUnits, '2010-01-22 15:29:55.090', '2010-01-22 15:30:09.153')

Substitute "MyUnits" based on DATEDIFF on MSDN

The question is already answered but I think I've found the solution that is simpler and more relevant to the question title, here it is:

var cli = new WebClient();
cli.Headers[HttpRequestHeader.ContentType] = "application/json";
string response = cli.UploadString("http://some/address", "{some:\"json data\"}");

PS: In the most of .net implementations, but not in all WebClient is IDisposable, so of cource it is better to do 'using' or 'Dispose' on it. However in this particular case it is not really necessary.

Following Linear / Grid LayoutManager methods can be used to check which items are visible

int findFirstVisibleItemPosition();
int findLastVisibleItemPosition();
int findFirstCompletelyVisibleItemPosition();
int findLastCompletelyVisibleItemPosition();

There is already a library in Python called yahoo_finance so you'll need to download the library first using the following command line:

sudo pip install yahoo_finance

Then once you've installed the yahoo_finance library, here's a sample code that will download the data you need from Yahoo Finance:

#!/usr/bin/python
import yahoo_finance
import pandas as pd

symbol = yahoo_finance.Share("GOOG")
google_data = symbol.get_historical("1999-01-01", "2016-06-30")
google_df = pd.DataFrame(google_data)

# Output data into CSV
google_df.to_csv("/home/username/google_stock_data.csv")

This should do it. Let me know if it works.

UPDATE: The yahoo_finance library is no longer supported.

string sample = "ratty";
Console.WriteLine(sample[0]);

And

Console.WriteLine(sample.Chars(0));

The above is same as using indexers in c#.

array_rand()

update: nowadays we have mobile and custom keyboards and we cannot continue trusting these arbitrary key codes such as 13 and 186. in other words, stop using event.which/event.keyCode and start using event.key:

if (event.key === "Enter" || event.key === "ArrowUp" || event.key === "ArrowDown")

See the fp.h file in the xll project at http://xll.codeplex.com It solves the "unwarranted chumminess with the compiler" issue for arrays that like to carry their dimensions around with them.

typedef struct _FP
{
    unsigned short int rows;
    unsigned short int columns;
    double array[1];        /* Actually, array[rows][columns] */
} FP;

By far the simplest (works for python) is '123-(apple|banana)-?456'.

You can try this code

import random
N = 5
count_list = range(1,N+1)
random.shuffle(count_list)

while count_list:
    value = count_list.pop()
    # do whatever you want with 'value'

Javascript with ECMAScript 5 standard which is supported by most browsers now, you can use apply() to append array1 to array2.

var array1 = [3, 4, 5];
var array2 = [1, 2];

Array.prototype.push.apply(array2, array1);

console.log(array2); // [1, 2, 3, 4, 5]

Javascript with ECMAScript 6 standard which is supported by Chrome and FF and IE Edge, you can use the spread operator:

"use strict";
let array1 = [3, 4, 5];
let array2 = [1, 2];

array2.push(...array1);

console.log(array2); // [1, 2, 3, 4, 5]

The spread operator will replace array2.push(...array1); with array2.push(3, 4, 5); when the browser is thinking the logic.

Bonus point

If you'd like to create another variable to store all the items from both array, you can do this:

ES5 var combinedArray = array1.concat(array2);

ES6 const combinedArray = [...array1, ...array2]

The spread operator (...) is to spread out all items from a collection.

This is not an answer per se, but here's something interesting:

$y = str_replace('z', 'e', 'zxzc');
$y("malicious code");

In the same spirit, call_user_func_array() can be used to execute obfuscated functions.

Another scenario where this occurs is when you have a base class and one or more subclasses, where at least one of the subclasses introduce extra properties:

class Folder {
  [key]
  public string Id { get; set; }

  public string Name { get; set; }
}

// Adds no props, but comes from a different view in the db to Folder:
class SomeKindOfFolder: Folder {
}

// Adds some props, but comes from a different view in the db to Folder:
class AnotherKindOfFolder: Folder {
  public string FolderAttributes { get; set; }
}

If these are mapped in the DbContext like below, the "'Invalid column name 'Discriminator'" error occurs when any type based on Folder base type is accessed:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
  modelBuilder.Entity<Folder>().ToTable("All_Folders");
  modelBuilder.Entity<SomeKindOfFolder>().ToTable("Some_Kind_Of_Folders");
  modelBuilder.Entity<AnotherKindOfFolder>().ToTable("Another_Kind_Of_Folders");
}

I found that to fix the issue, we extract the props of Folder to a base class (which is not mapped in OnModelCreating()) like so - OnModelCreating should be unchanged:

class FolderBase {
  [key]
  public string Id { get; set; }

  public string Name { get; set; }
}

class Folder: FolderBase {
}

class SomeKindOfFolder: FolderBase {
}

class AnotherKindOfFolder: FolderBase {
  public string FolderAttributes { get; set; }
}

This eliminates the issue, but I don't know why!

It would be

String MyStr = ListBox.items[5].ToString();

"matt b" has it right, but to be specific, the "install" goal copies your built target to the local repository on your file system; useful for small changes across projects not currently meant for the full group.

The "deploy" goal uploads it to your shared repository for when your work is finished, and then can be shared by other people who require it for their project.

In your case, it seems that "install" is used to make the management of the deployment easier since CI's local repo is the shared repo. If CI was on another box, it would have to use the "deploy" goal.

You can set the border properties on the CALayer by accessing the layer property of the button.

First, add Quartz

#import <QuartzCore/QuartzCore.h>

Set properties:

myButton.layer.borderWidth = 2.0f;
myButton.layer.borderColor = [UIColor greenColor].CGColor;

See:

https://developer.apple.com/documentation/quartzcore/calayer#//apple_ref/occ/cl/CALayer

The CALayer in the link above allows you to set other properties like corner radius, maskToBounds etc...

Following up on Kev's answer, using the Postgres docs:

First, create an array of the elements, then use the built-in array_to_string function.

CREATE AGGREGATE array_accum (anyelement)
(
 sfunc = array_append,
 stype = anyarray,
 initcond = '{}'
);

select array_to_string(array_accum(name),'|') from table group by id;

If your variable is used only within the context of a single function, you're better off using a stack variable, i.e., Option 2. As others have said, you do not have to manage the lifetime of stack variables - they are constructed and destructed automatically. Also, allocating/deallocating a variable on the heap is slow by comparison. If your function is called often enough, you'll see a tremendous performance improvement if use stack variables versus heap variables.

That said, there are a couple of obvious instances where stack variables are insufficient.

If the stack variable has a large memory footprint, then you run the risk of overflowing the stack. By default, the stack size of each thread is 1 MB on Windows. It is unlikely that you'll create a stack variable that is 1 MB in size, but you have to keep in mind that stack utilization is cumulative. If your function calls a function which calls another function which calls another function which..., the stack variables in all of these functions take up space on the same stack. Recursive functions can run into this problem quickly, depending on how deep the recursion is. If this is a problem, you can increase the size of the stack (not recommended) or allocate the variable on the heap using the new operator (recommended).

The other, more likely condition is that your variable needs to "live" beyond the scope of your function. In this case, you'd allocate the variable on the heap so that it can be reached outside the scope of any given function.

Correct, np.log(x) is the Natural Log (base e log) of x.

For other bases, remember this law of logs: log-b(x) = log-k(x) / log-k(b) where log-b is the log in some arbitrary base b, and log-k is the log in base k, e.g.

here k = e

l = np.log(x) / np.log(100)

and l is the log-base-100 of x

As the message says:

no changes added to commit (use "git add" and/or "git commit -a")

Git has a "staging area" where files need to be added before being committed, you can read an explanation of it here.

For your specific example, you can use:

git commit -am "save arezzo files"

(note the extra a in the flags, can also be written as git commit -a -m "message" - both do the same thing)

Alternatively, if you want to be more selective about what you add to the commit, you use the git add command to add the appropriate files to the staging area, and git status to preview what is about to be added (remembering to pay attention to the wording used).

You can also find general documentation and tutorials for how to use git on the git documentation page which will give more detail about the concept of staging/adding files.

One other thing worth knowing about is interactive staging - this allows you to add parts of a file to the staging area, so if you've made three distinct code changes (for related but different functionality), you can use interactive mode to split the changes and add/commit each part in turn. Having smaller specific commits like this can be helpful.

Not all HTML and CSS is supported by Microsoft Office products, Outlook in particular; take a look here for reference on supported elements for what you can and can't use in Outlook when rendering HTML.

Specifically, from that link it doesn't state the background CSS property is supported for div elements. You might have to use an img and do some hacky layering.

Note that in your second example you have a quote mismatch, which won't help any.

Lastly and something I just came across at the link provided is the Outlook HTML and CSS Validator tool - you could try running that against your newsletter markup and see if it gives you any suggestions/alternatives.

If you have few modal shown simultaneously you can specify target modal for in-modal button with attributes data-toggle and data-target:

<div class="modal fade in" id="sendMessageModal" tabindex="-1" role="dialog" aria-hidden="true">
      <div class="modal-dialog modal-sm">
           <div class="modal-content">
                <div class="modal-header text-center">
                     <h4 class="modal-title">Modal Title</h4>
                     <small>Modal Subtitle</small>
                </div>
                <div class="modal-body">
                     <p>Modal content text</p>
                </div>
                <div class="modal-footer">
                     <button type="button" class="btn btn-default pull-left" data-toggle="modal" data-target="#sendMessageModal">Close</button>
                     <button type="button" class="btn btn-danger" data-toggle="modal" data-target="#sendMessageModal">Send</button>
                </div>
           </div>
      </div>
 </div>

Somewhere outside the modal code you can have another toggle button:

<a href="index.html#" class="btn btn-default btn-xs" data-toggle="modal" data-target="#sendMessageModal">Resend Message</a>

User can't click in-modal toggle button while these button hidden and it correct works with option "modal" for attribute data-toggle. This scheme works automagicaly!

You can also use pyodbc with the MySQL Connector/ODBC to use MySQL on Windows. Unixodbc is also available to make the code compatible on Linux. Pyodbc uses the standard Python DB API 2.0 so if you stick with that switching between MySQL/PostgreSQL/SQLite/ODBC/JDBC drivers etc. should be relatively painless.

evidently, as stated in the parser response, a column name is needed for both cases. In either versions the columns of "d" are not named.

in case 1: your column 2 of d is sum(totalitems) which is not named. duration will retain the name "duration"

in case 2: both month(clothdeliverydate) and SUM(CONVERT(INT, deliveredqty)) have to be named

The RemoveAll() methods accept a Predicate<T> delegate (until here nothing new). A predicate points to a method that simply returns true or false. Of course, the RemoveAll will remove from the collection all the T instances that return True with the predicate applied.

C# 3.0 lets the developer use several methods to pass a predicate to the RemoveAll method (and not only this one…). You can use:

Lambda expressions

vehicles.RemoveAll(vehicle => vehicle.EnquiryID == 123);

Anonymous methods

vehicles.RemoveAll(delegate(Vehicle v) {
  return v.EnquiryID == 123;
});

Normal methods

vehicles.RemoveAll(VehicleCustomPredicate);
private static bool
VehicleCustomPredicate (Vehicle v) {
    return v.EnquiryID == 123; 
}

Here's an approach I'm using for ember 1.10 and ember-cli 2.0.

// app/helpers/js-x.js
export default Ember.HTMLBars.makeBoundHelper(function (params) {
  var paramNames = params.slice(1).map(function(val, idx) { return "p" + idx; });
  var func = Function.apply(this, paramNames.concat("return " + params[0] + ";"))
  return func.apply(params[1] === undefined ? this : params[1], params.slice(1));
});

Then you can use it in your templates like this:

// used as sub-expression
{{#each item in model}}
  {{#if (js-x "this.section1 || this.section2" item)}}
  {{/if}}
{{/each}}

// used normally
{{js-x "p0 || p1" model.name model.offer.name}}

Where the arguments to the expression are passed in as p0,p1,p2 etc and p0 can also be referenced as this.

Method for comparing 2 dates (util.date or sql.date)

 public static boolean isSameDay(Date a, Date b) {
    Calendar calA = new GregorianCalendar();
    calA.setTime(a);

    Calendar calB = new GregorianCalendar();
    calB.setTime(b);

    final int yearA = calA.get(Calendar.YEAR);
    final int monthA = calA.get(Calendar.MONTH);
    final int dayA = calA.get(Calendar.DAY_OF_YEAR);

    final int yearB = calB.get(Calendar.YEAR);
    final int monthB = calB.get(Calendar.MONTH);
    final int dayB = calB.get(Calendar.DAY_OF_YEAR);

    return yearA == yearB && monthA == monthB && dayA == dayB;
}

Least effort solution for me was to make use of the gradle-shadow-plugin

Besides applying the plugin all that needs to be done is:

Configure the jar task to put your Main class into manifest

jar {
  manifest {
   attributes 'Main-Class': 'com.my.app.Main'
  }
}

Run the gradle task

./gradlew shadowJar

Take the app-version-all.jar from build/libs/

And finally execute it via:

java -jar app-version-all.jar

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

There's also the Java 7 solution, using the new(ish) Path abstraction:

Path fileToDeletePath = Paths.get("fileToDelete_jdk7.txt");
Files.delete(fileToDeletePath);

Hope this helps.

I could solve this in another way. I didn't find the library on my system. Thus I installed it using an app from PostgreSQL main website. In my case (OS X) I found the file under /Library/PostgreSQL/9.1/include/ once the installation was over. You may also have the file somewhere else depending on your system if you already have PostgreSQL installed.

Thanks to this link on how to add an additional path for gem installation, I could point the gem to the lib with this command:

export CONFIGURE_ARGS="with-pg-include=/Library/PostgreSQL/9.1/include/"
gem install pg

After that, it works, because it now knows where to find the missing library. Just replace the path with the right location for your libpq-fe.h

Authentication is done via a simple ldap_bind command that takes the users DN and the password. The user is authenticated when the bind is successfull. Usually you would get the users DN via an ldap_search based on the users uid or email-address.

Getting the users roles is something different as it is an ldap_search and depends on where and how the roles are stored in the ldap. But you might be able to retrieve the roles during the lap_search used to find the users DN.

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -

Base Functions

def a(x):
    print('a')
    return x

def b(x):
    print('b')
    return x 

AND

if(a(True) and b(True)):
    print(1,end='\n\n')

if(a(False) and b(True)):
    print(2,end='\n\n') 

AND-OUTPUT

a
b
1

a 

OR

if(a(True) or b(False)):
    print(3,end='\n\n')

if(a(False) or b(True)):
    print(4,end='\n\n') 

OR-OUTPUT

a

a
b

I had an experience with DataGrid. One of it's columns was "Select" button. When I was clicking "Select" button of any row I had received this error message:

"Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

I changed several codes, and finally I succeeded. My experience route:

1) I changed page attribute to EnableEventValidation="false". But it didn't work. (not only is this dangerous for security reason, my event handler wasn't called: void Grid_SelectedIndexChanged(object sender, EventArgs e)

2) I implemented ClientScript.RegisterForEventValidation in Render method. But it didn't work.

protected override void Render(HtmlTextWriter writer)
{
    foreach (DataGridItem item in this.Grid.Items)
    {
        Page.ClientScript.RegisterForEventValidation(item.UniqueID);
        foreach (TableCell cell in (item as TableRow).Cells)
        {
            Page.ClientScript.RegisterForEventValidation(cell.UniqueID);
            foreach (System.Web.UI.Control control in cell.Controls)
            {
                if (control is Button)
                    Page.ClientScript.RegisterForEventValidation(control.UniqueID);
            }
        }
    }
}

3) I changed my button type in grid column from PushButton to LinkButton. It worked! ("ButtonType="LinkButton"). I think if you can change your button to other controls like "LinkButton" in other cases, it would work properly.

There are some inconsistencies in how browsers expose the current window scrolling coordinates. Google Chrome on Mac and iOS seems to always return 0 when using document.documentElement.scrollTop or jQuery's $(window).scrollTop().

However, it works consistently with:

// horizontal scrolling amount
window.pageXOffset

// vertical scrolling amount
window.pageYOffset

I find it useful, because when I didn't know about env, before I started to write script I was doing this:

type nodejs > scriptname.js #or any other environment

and then I was modifying that line in the file into shebang.
I was doing this, because I didn't always remember where is nodejs on my computer -- /usr/bin/ or /bin/, so for me env is very useful. Maybe there are details with this, but this is my reason

You can create the sql to update all tables with:

SELECT CONCAT("ALTER TABLE ",TABLE_SCHEMA,".",TABLE_NAME," CHARACTER SET utf8 COLLATE utf8_general_ci;   ",
    "ALTER TABLE ",TABLE_SCHEMA,".",TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  ") 
    AS alter_sql
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = "your_database_name";

Capture the output and run it.

Recursion can be hard to grasp sometimes. Just evaluate it on a piece of paper for a small number:

fib(4)
-> fib(3) + fib(2)
-> fib(2) + fib(1) + fib(1) + fib(0)
-> fib(1) + fib(0) + fib(1) + fib(1) + fib(0)
-> 1 + 0 + 1 + 1 + 0
-> 3

I am not sure how Java actually evaluates this, but the result will be the same.

 SELECT * FROM ALL_source WHERE UPPER(text) LIKE '%BLAH%'

EDIT Adding additional info:

 SELECT * FROM DBA_source WHERE UPPER(text) LIKE '%BLAH%'

The difference is dba_source will have the text of all stored objects. All_source will have the text of all stored objects accessible by the user performing the query. Oracle Database Reference 11g Release 2 (11.2)

Another difference is that you may not have access to dba_source.

THIS_DIR := $(dir $(abspath $(firstword $(MAKEFILE_LIST))))

for any extra column if there is no mapping then map it to null like the following SQL query

Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2````

Curry can simplify your code. This is one of the main reasons to use this. Currying is a process of converting a function that accepts n arguments into n functions that accept only one argument.

The principle is to pass the arguments of the passed function, using the closure (closure) property, to store them in another function and treat it as a return value, and these functions form a chain, and the final arguments are passed in to complete the operation.

The benefit of this is that it can simplify the processing of parameters by dealing with one parameter at a time, which can also improve the flexibility and readability of the program. This also makes the program more manageable. Also dividing the code into smaller pieces would make it reuse-friendly.

For example:

function curryMinus(x) 
{
  return function(y) 
  {
    return x - y;
  }
}

var minus5 = curryMinus(1);
minus5(3);
minus5(5);

I can also do...

var minus7 = curryMinus(7);
minus7(3);
minus7(5);

This is very great for making complex code neat and handling of unsynchronized methods etc.

Use the Debug.WriteLine. This will display your message in the Output window immediately. The only restriction is that you must run your test in Debug mode.

[TestMethod]
public void TestMethod1()
{
    Debug.WriteLine("Time {0}", DateTime.Now);
    System.Threading.Thread.Sleep(30000);
    Debug.WriteLine("Time {0}", DateTime.Now);
}

Updating curl worked for us. Somehow yum uses curl for its transactions.

yum update curl --disablerepo=epel

It is also possible to int array to direct assign value.

like this

int[] numbers = sNumbers.Split(',').Select(Int32.Parse).ToArray();

This is the simplest way to do it.

let total = parseInt(('100,000.00'.replace(',',''))) + parseInt(('500,000.00'.replace(',','')))

Unitialized variables check. Link 1 and 2 already seem to do this just fine, though.

I can't say I have used any of these intensively, though :)

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

This match 6 or more any chars but newline:

/^.{6,}$/

There is way to do that ;)

I literally just wanted the first row of my data which are the headers I need and didn't want to iterate over all my data to get them, so I just did this:

with open(data, 'r', newline='') as csvfile:
t = 0
for i in csv.reader(csvfile, delimiter=',', quotechar='|'):
    if t > 0:
        break
    else:
        dbh = i
        t += 1

By default, the created subprocess does not have its own terminal or console. All its standard I/O (i.e. stdin, stdout, stderr) operations will be redirected to the parent process, where they can be accessed via the streams obtained using the methods getOutputStream(), getInputStream(), and getErrorStream(). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, or even deadlock.

This did the trick for me:

var express = require('express'),
app = express(); 
app.use('/', express.static(__dirname + '/'));
app.listen(8080);

this will subtract ten days of the current date (before Java 8):

int x = -10;
Calendar cal = GregorianCalendar.getInstance();
cal.add( Calendar.DAY_OF_YEAR, x);
Date tenDaysAgo = cal.getTime();

If you're using Java 8 you can make use of the new Date & Time API (http://www.oracle.com/technetwork/articles/java/jf14-date-time-2125367.html):

LocalDate tenDaysAgo = LocalDate.now().minusDays(10);

For converting the new to the old types and vice versa see: Converting between java.time.LocalDateTime and java.util.Date

For iOS 7 in a single view use in viewWillappear method:

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];

For display the status bar use:

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];

You can use any country code, yes, but that doesn't mean a browser or other software will recognize it or do anything differently because of it. For example, a screen reader might deal with "en-US" and "en-GB" the same if they only support an American accent in English. Another piece of software that has two distinct voices, though, could adjust according to the country code.

SELECT   col,

Make sure you pip version matches your python version.

to get your python version use:

python -V

then install the correct pip. You might already have intall in that case try to use:

pip-2.5 install ...

pip-2.7 install ...

or for those of you using macports make sure your version match using.

port select --list pip

then change to the same python version you are using.

sudo port select --set pip pip27

Hope this helps. It work on my end.

You can replace an HTML Element or Node using Node.replaceWith(newNode).

This example should keep all attributes and childs from origin node:

const links = document.querySelectorAll('a')

links.forEach(link => {
  const replacement = document.createElement('span')
  
  // copy attributes
  for (let i = 0; i < link.attributes.length; i++) {
     const attr = link.attributes[i]
     replacement.setAttribute(attr.name, attr.value)
  }
  
  // copy content
  replacement.innerHTML = link.innerHTML
  
  // or you can use appendChild instead
  // link.childNodes.forEach(node => replacement.appendChild(node))

  link.replaceWith(replacement)
})

If you have these elements:

<a href="#link-1">Link 1</a>
<a href="#link-2">Link 2</a>
<a href="#link-3">Link 3</a>
<a href="#link-4">Link 4</a>

After running above codes, you will end up with these elements:

<span href="#link-1">Link 1</span>
<span href="#link-2">Link 2</span>
<span href="#link-3">Link 3</span>
<span href="#link-4">Link 4</span>

Open CMD with administrative access(Right click then run as administrator) then type the following command there:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

Replace My_python_lib with the folder name of your installed python like for me it was C:\python27. Then to check if the path variable is set, type echo %PATH% you'll see your python part in the end. Hence now python is accessible. From this tutorial

Use the axis argument:

>> numpy.sum(a, axis=0)
  array([18, 22, 26])

Yes you can.... you can place something on top of the link element.

the magic sauce happens at product-type-simple:before class Whats happening here is that for each element that has class of product-type-simple you create something that has the width and height equal to that of the product-type-simple , then you increase its z-index to make sure it will place it self on top of the content of product-type-simple. You can toggle the background color if you want to see whats going on.

Use the second argument on the Mockito.verify method, as in:

Mockito.verify(dependency, Mockito.times(0)).someMethod()

We can get KEY from VALUE. Below is a sample code_

 public class Main {
  public static void main(String[] args) {
    Map map = new HashMap();
    map.put("key_1","one");
    map.put("key_2","two");
    map.put("key_3","three");
    map.put("key_4","four");

    System.out.println(getKeyFromValue(map,"four"));
  }
  public static Object getKeyFromValue(Map hm, Object value) {
    for (Object o : hm.keySet()) {
      if (hm.get(o).equals(value)) {
        return o;
      }
    }
    return null;
  }
}

I hope this will help everyone.

After installing mongodb through brew, run this to get it up and running:

mongod --dbpath /usr/local/var/mongodb

When working with bootsrap usually face three main problems:

1. How to place the content of the column to the bottom?
2. How to create a multi-row gallery of columns of equal height in one .row?
3. How to center columns horizontally if their total width is less than 12 and the remaining width is odd?

To solve first two problems download this small plugin https://github.com/codekipple/conformity

The third problem is solved here http://www.minimit.com/articles/solutions-tutorials/bootstrap-3-responsive-centered-columns

Common code

<style>
    [class*=col-] {position: relative}
    .row-conformity .to-bottom {position:absolute; bottom:0; left:0; right:0}
    .row-centered {text-align:center}   
    .row-centered [class*=col-] {display:inline-block; float:none; text-align:left; margin-right:-4px; vertical-align:top} 
</style>

<script src="assets/conformity/conformity.js"></script>
<script>
    $(document).ready(function () {
        $('.row-conformity > [class*=col-]').conformity();
        $(window).on('resize', function() {
            $('.row-conformity > [class*=col-]').conformity();
        });
    });
</script>

1. Aligning content of the column to the bottom

<div class="row row-conformity">
    <div class="col-sm-3">
        I<br>create<br>highest<br>column
    </div>
    <div class="col-sm-3">
        <div class="to-bottom">
            I am on the bottom
        </div>
    </div>
</div>

2. Gallery of columns of equal height

<div class="row row-conformity">
    <div class="col-sm-4">We all have equal height</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
</div>

3. Horizontal alignment of columns to the center (less than 12 col units)

<div class="row row-centered">
    <div class="col-sm-3">...</div>
    <div class="col-sm-4">...</div>
</div>

All classes can work together

<div class="row row-conformity row-centered">
    ...
</div>

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

The Syntax page should get you started with the basics.

We can simply use Collections.max() and Collections.min() method.

public class MaxList {
    public static void main(String[] args) {
        List l = new ArrayList();
        l.add(1);
        l.add(2);
        l.add(3);
        l.add(4);
        l.add(5);
        System.out.println(Collections.max(l)); // 5
        System.out.println(Collections.min(l)); // 1
    }
}
