The browser is connected to the proxy so the data that the proxy gets from the web server is just sent via the same connection that the browser initiated to the proxy.
ok so I used this:
public partial class Form1 : Form
{
private void Button_Click(object sender, EventArgs e)
{
Form2 myForm = new Form2();
this.Hide();
myForm.ShowDialog();
this.Close();
}
}
This seems to be working fine but the first form is just hidden and it can still generate events. the "this.Close()" is needed to close the first form but if you still want your form to run (and not act like a launcher) you MUST replace it with
this.Show();
Best of luck!
This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.
If you're using SQL Server, use the SqlBulkCopy class.
For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.
One other difference not mentioned so far is that
Clone()
the destination array need not exist yet since a new one is created from scratch.CopyTo()
not only does the destination array need to already exist, it needs to be large enough to hold all the elements in the source array from the index you specify as the destination.DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);
assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.
The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.
As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.
If you need to parse other formats, you can check out the Standard DateTime Format Strings.
You should be able to read the GUID attribute of the assembly via reflection. This will get the GUID for the current assembly
Assembly asm = Assembly.GetExecutingAssembly();
var attribs = (asm.GetCustomAttributes(typeof(GuidAttribute), true));
Console.WriteLine((attribs[0] as GuidAttribute).Value);
You can replace the GuidAttribute with other attributes as well, if you want to read things like AssemblyTitle, AssemblyVersion, etc.
You can also load another assembly (Assembly.LoadFrom and all) instead of getting the current assembly - if you need to read these attributes of external assemblies (for example, when loading a plugin).
Expanding on C. Dragon 76's popular answer by making his code into an extension that overloads the default Replace
method.
public static class StringExtensions
{
public static string Replace(this string str, string oldValue, string newValue, StringComparison comparison)
{
StringBuilder sb = new StringBuilder();
int previousIndex = 0;
int index = str.IndexOf(oldValue, comparison);
while (index != -1)
{
sb.Append(str.Substring(previousIndex, index - previousIndex));
sb.Append(newValue);
index += oldValue.Length;
previousIndex = index;
index = str.IndexOf(oldValue, index, comparison);
}
sb.Append(str.Substring(previousIndex));
return sb.ToString();
}
}
This solution produces a result list, that contains all differences from both input lists. You can compare your objects by any property, in my example it is ID. The only restriction is that the lists should be of the same type:
var DifferencesList = ListA.Where(x => !ListB.Any(x1 => x1.id == x.id))
.Union(ListB.Where(x => !ListA.Any(x1 => x1.id == x.id)));
Brilliant! That's all I can say.
Here is a VB variant of the updated code (not in a class, just a function) that will clean up and also sanitize the xml
Function cXML(ByVal _buf As String) As String
Dim textOut As New StringBuilder
Dim c As Char
If _buf.Trim Is Nothing OrElse _buf = String.Empty Then Return String.Empty
For i As Integer = 0 To _buf.Length - 1
c = _buf(i)
If Entities.ContainsKey(c) Then
textOut.Append(Entities.Item(c))
ElseIf (AscW(c) = &H9 OrElse AscW(c) = &HA OrElse AscW(c) = &HD) OrElse ((AscW(c) >= &H20) AndAlso (AscW(c) <= &HD7FF)) _
OrElse ((AscW(c) >= &HE000) AndAlso (AscW(c) <= &HFFFD)) OrElse ((AscW(c) >= &H10000) AndAlso (AscW(c) <= &H10FFFF)) Then
textOut.Append(c)
End If
Next
Return textOut.ToString
End Function
Shared ReadOnly Entities As New Dictionary(Of Char, String)() From {{""""c, """}, {"&"c, "&"}, {"'"c, "'"}, {"<"c, "<"}, {">"c, ">"}}
Just use:
param.AddWithValue("@Date_Of_Birth",DOB);
That will take care of all your problems.
If you're feeling creative you could do something like this. Loop backwards through the dictionary to make your changes.
Dictionary<string, int> collection = new Dictionary<string, int>();
collection.Add("value1", 9);
collection.Add("value2", 7);
collection.Add("value3", 5);
collection.Add("value4", 3);
collection.Add("value5", 1);
for (int i = collection.Keys.Count; i-- > 0; ) {
if (collection.Values.ElementAt(i) < 5) {
collection.Remove(collection.Keys.ElementAt(i)); ;
}
}
Certainly not identical, but you might be interested anyways...
To programmatically maximize the windowstate you can use:
this.WindowState = FormWindowState.Maximized;
this.MaximizeBox = false;
I've used the code above that solves the problem using regex and it works, but it's quite slow. It reads the entire file to determine the number of pages.
I used it in a web app and pages would sometimes list 20 or 30 PDFs at a time and in that circumstance the load time for the page went from a couple seconds to almost a minute due to the page counting method.
I don't know if the 3rd party libraries are much better, I would hope that they are and I've used pdflib in other scenarios with success.
This will work for an environment variable that is machine setting. For Users, just change to User instead.
String EnvironmentPath = System.Environment
.GetEnvironmentVariable("Variable_Name", EnvironmentVariableTarget.Machine);

If you want specific users to have access to all or part of the WMI object space, you need to permission them as shown here. Note that you have to be running on as an admin to perform this setting.
After having this problem on remote servers (production, test, qa, staging, etc), but not on local development workstations, I found that the Application Pool was configured with a RequestLimit other than 0.
This caused the app pool to give up and reply with the exception noted in the question.
I got this error too, but my problem was that I was using an older version of GACUTIL.EXE
.
Once I had the correct GACUTIL
for the latest .NET
version installed, it worked fine.
The error is misleading because it makes it look like it's the DLL you're trying to register that incorrect.
I can't see any native .NET way to do it but if you want to get your hands dirty with the underlying Win32 controls...
You should be able to send it the CB_GETCOMBOBOXINFO
message with a COMBOBOXINFO
structure which will contain the internal edit control's handle.
You can then send the edit control the EM_SETCUEBANNER
message with a pointer to the string.
(Note that this requires at least XP and visual styles to be enabled.
Use this to get the installed Windows architecture:
string getOSArchitecture()
{
string architectureStr;
if (Directory.Exists(Environment.GetFolderPath(
Environment.SpecialFolder.ProgramFilesX86))) {
architectureStr ="64-bit";
}
else {
architectureStr = "32-bit";
}
return architectureStr;
}
You can implement custom iComparer to do sorting. Read the file info for files and compare as you like.
IComparer comparer = new YourCustomComparer();
Array.Sort(System.IO.Directory.GetFiles(), comparer);
I got this error while running unit tests on inmemory caching I was setting up. It flooded the cache. After invalidating the cache and restarting the VM, it worked fine.

Just in case if someone stumbles onto this thread then here is a bullet proof solution to SQL Server stuck in SINGLE USER MODE
-- Get the process ID (spid) of the connection you need to kill
-- Replace 'DBName' with the actual name of the DB
SELECT sd.[name], sp.spid, sp.login_time, sp.loginame
FROM sysprocesses sp
INNER JOIN sysdatabases sd on sp.dbid = sd.dbid
WHERE sd.[name] = 'DBName'
As an alternative, you can also use the command “sp_who” to get the “spid” of the open connection:
-- Or use this SP instead
exec sp_who
-- Then Execute the following and replace the [spid] and [DBName] with correct values
KILL SpidToKillGoesHere
GO
SET DEADLOCK_PRIORITY HIGH
GO
ALTER DATABASE [DBName] SET MULTI_USER WITH ROLLBACK IMMEDIATE
GO
Use the following representation instead:
local items = { apple=true, orange=true, pear=true, banana=true }
if items.apple then
...
end
Using your code with some random data, this would work:
fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)
axs = axs.ravel()
for i in range(10):
axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
axs[i].set_title(str(250+i))
The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).
You CANNOT do this - you cannot attach/detach or backup/restore a database from a newer version of SQL Server down to an older version - the internal file structures are just too different to support backwards compatibility. This is still true in SQL Server 2014 - you cannot restore a 2014 backup on anything other than another 2014 box (or something newer).
You can either get around this problem by
using the same version of SQL Server on all your machines - then you can easily backup/restore databases between instances
otherwise you can create the database scripts for both structure (tables, view, stored procedures etc.) and for contents (the actual data contained in the tables) either in SQL Server Management Studio (Tasks > Generate Scripts
) or using a third-party tool
or you can use a third-party tool like Red-Gate's SQL Compare and SQL Data Compare to do "diffing" between your source and target, generate update scripts from those differences, and then execute those scripts on the target platform; this works across different SQL Server versions.
The compatibility mode setting just controls what T-SQL features are available to you - which can help to prevent accidentally using new features not available in other servers. But it does NOT change the internal file format for the .mdf
files - this is NOT a solution for that particular problem - there is no solution for restoring a backup from a newer version of SQL Server on an older instance.
Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW
, FIRST_COL
, and LAST_COL
, and that _xlSheet
is the name of the ExcelSheet
(using Microsoft.Interop.Excel
)
First, define the range:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
Then, set the background color of that range:
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
Finally, set the font color:
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
And here's the code combined:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
Adel Hazzah's answer gives working code, Daniel Widdis's and Nedko's comments mention that you need to query Win32_USBControllerDevice and use its Dependent property, and Daniel's answer gives a lot of detail without code.
Here's a synthesis of the above discussion to provide working code that lists the directly accessible PNP device properties of all connected USB devices:
using System;
using System.Collections.Generic;
using System.Management; // reference required
namespace cSharpUtilities
{
class UsbBrowser
{
public static void PrintUsbDevices()
{
IList<ManagementBaseObject> usbDevices = GetUsbDevices();
foreach (ManagementBaseObject usbDevice in usbDevices)
{
Console.WriteLine("----- DEVICE -----");
foreach (var property in usbDevice.Properties)
{
Console.WriteLine(string.Format("{0}: {1}", property.Name, property.Value));
}
Console.WriteLine("------------------");
}
}
public static IList<ManagementBaseObject> GetUsbDevices()
{
IList<string> usbDeviceAddresses = LookUpUsbDeviceAddresses();
List<ManagementBaseObject> usbDevices = new List<ManagementBaseObject>();
foreach (string usbDeviceAddress in usbDeviceAddresses)
{
// query MI for the PNP device info
// address must be escaped to be used in the query; luckily, the form we extracted previously is already escaped
ManagementObjectCollection curMoc = QueryMi("Select * from Win32_PnPEntity where PNPDeviceID = " + usbDeviceAddress);
foreach (ManagementBaseObject device in curMoc)
{
usbDevices.Add(device);
}
}
return usbDevices;
}
public static IList<string> LookUpUsbDeviceAddresses()
{
// this query gets the addressing information for connected USB devices
ManagementObjectCollection usbDeviceAddressInfo = QueryMi(@"Select * from Win32_USBControllerDevice");
List<string> usbDeviceAddresses = new List<string>();
foreach(var device in usbDeviceAddressInfo)
{
string curPnpAddress = (string)device.GetPropertyValue("Dependent");
// split out the address portion of the data; note that this includes escaped backslashes and quotes
curPnpAddress = curPnpAddress.Split(new String[] { "DeviceID=" }, 2, StringSplitOptions.None)[1];
usbDeviceAddresses.Add(curPnpAddress);
}
return usbDeviceAddresses;
}
// run a query against Windows Management Infrastructure (MI) and return the resulting collection
public static ManagementObjectCollection QueryMi(string query)
{
ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher(query);
ManagementObjectCollection result = managementObjectSearcher.Get();
managementObjectSearcher.Dispose();
return result;
}
}
}
You'll need to add exception handling if you want it. Consult Daniel's answer if you want to figure out the device tree and such.

I had this problem, and the cause was that I had not added the Microsoft.Owin.Host.SystemWeb NuGet package to my project. Although the code in my startup class was correct, it was not being executed.
So if you're trying to solve this problem, put a breakpoint in the code where you do the Unity registrations. If you don't hit it, your dependency injection isn't going to work.
I was getting this error because my cpp files was not added in the CMakeLists.txt file
Here's my solution if you created the repository with some default readme file
or license
git init
git add -A
git commit -m "initial commit"
git remote add origin https://<git-userName>@github.com/xyz.git //Add your username so it will avoid asking username each time before you push your code
git fetch
git pull https://github.com/xyz.git <branch>
git push origin <branch>
You can use max-height
in an inline style
attribute, as below:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
To use scrolling with content that overflows a given max-height
, you can alternatively try the following:
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>
To restrict the height to a fixed value you can use something like this.
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>
Specify the same value for both max-height
and min-height
(either in pixels or in points – as long as it’s consistent).
You can also put the same styles in css class in a stylesheet (or a style
tag as shown below) and then include the same in your tag. See below:
Style Code:
.fixed-panel {
min-height: 10;
max-height: 10;
overflow-y: scroll;
}
Apply Style :
<div class="panel panel-primary">
<div class="panel-heading">jhdsahfjhdfhs</div>
<div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>
Hope this helps with your need.
Primefaces uses cookie polling, too
monitorDownload: function(start, complete, monitorKey) {
if(this.cookiesEnabled()) {
if(start) {
start();
}
var cookieName = monitorKey ? 'primefaces.download_' + monitorKey : 'primefaces.download';
window.downloadMonitor = setInterval(function() {
var downloadComplete = PrimeFaces.getCookie(cookieName);
if(downloadComplete === 'true') {
if(complete) {
complete();
}
clearInterval(window.downloadMonitor);
PrimeFaces.setCookie(cookieName, null);
}
}, 1000);
}
},
In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia
In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict
) into its valid JSON pendant (object).
True
will be converted to JSONs true
and the dictionary itself will then be encapsulated in quotes.True
/ False
, true
/ false
json
is the standard way to do serialization:Code example:
data = {
"president": {
"name": "Zaphod Beeblebrox",
"species": "Betelgeusian",
"male": True,
}
}
import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize
# serialized json_data now looks like:
# {
# "president": {
# "name": "Zaphod Beeblebrox",
# "species": "Betelgeusian",
# "male": true
# }
# }
Source: realpython.com
If you use the FIND_IN_SET
function:
FIND_IN_SET(a, columnname)
yields all the records that have "a" in them, alone or with others
AND
FIND_IN_SET(columnname, a)
yields only the records that have "a" in them alone, NOT the ones with the others
So if record1 is (a,b,c) and record2 is (a)
FIND_IN_SET(columnname, a)
yields only record2 whereas FIND_IN_SET(a, columnname)
yields both records.
Using this is NOT enough:
if($_SERVER["HTTPS"] != "on")
{
header("Location: https://" . $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]);
exit();
}
If you have any http content (like an external http image source), the browser will detect a possible threat. So be sure all your ref and src inside your code are https
If you bind the event through mootools' addEvent function your event handler will get a fixed (augmented) event passed as the parameter. It will always contain the preventDefault() method.
Try out this fiddle to see the difference in event binding. http://jsfiddle.net/pFqrY/8/
// preventDefault always works
$("mootoolsbutton").addEvent('click', function(event) {
alert(typeof(event.preventDefault));
});
// preventDefault missing in IE
<button
id="htmlbutton"
onclick="alert(typeof(event.preventDefault));">
button</button>
For all jQuery users out there you can fix an event when needed. Say that you used HTML onclick=".." and get a IE specific event that lacks preventDefault(), just use this code to get it.
e = $.event.fix(e);
After that e.preventDefault(); works fine.
You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree
option for single commands, or the GIT_WORK_TREE
environment variable. There is also the core.worktree
configuration option but it will not work in a bare repository (check the man page for what it does).
# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status
cat filename | grep -v "pattern" > filename.1
mv filename.1 filename
If you're using .NET 3.5, you can use DataTableExtensions.AsEnumerable
(an extension method) and then if you really need a List<DataRow>
instead of just IEnumerable<DataRow>
you can call Enumerable.ToList
:
IEnumerable<DataRow> sequence = dt.AsEnumerable();
or
using System.Linq;
...
List<DataRow> list = dt.AsEnumerable().ToList();
I'm saying the same thing as the other guys, so everyone's correct, I'm just trying to make it more clear.
@@IDENTITY
returns the id of the last thing that was inserted by your client's connection to the database.
Most of the time this works fine, but sometimes a trigger will go and insert a new row that you don't know about, and you'll get the ID from this new row, instead of the one you want
SCOPE_IDENTITY()
solves this problem. It returns the id of the last thing that you inserted in the SQL code you sent to the database. If triggers go and create extra rows, they won't cause the wrong value to get returned. Hooray
IDENT_CURRENT
returns the last ID that was inserted by anyone. If some other app happens to insert another row at an unforunate time, you'll get the ID of that row instead of your one.
If you want to play it safe, always use SCOPE_IDENTITY()
. If you stick with @@IDENTITY
and someone decides to add a trigger later on, all your code will break.

One thing I've struggled is that for ZonedDateTime timezone being changed to GMT during deserialization. Turned out, that by default jackson replaces it with one from context.. To keep zone one must disable this 'feature'

Process of generating RPM from source file:
Here's my take at it. The assumption is, when the URL changes but there has no click within the document
detected, it's a browser back (yes, or forward). A users click is reset after 2 seconds to make this work on pages that load content via Ajax:
(function(window, $) {
var anyClick, consoleLog, debug, delay;
delay = function(sec, func) {
return setTimeout(func, sec * 1000);
};
debug = true;
anyClick = false;
consoleLog = function(type, message) {
if (debug) {
return console[type](message);
}
};
$(window.document).click(function() {
anyClick = true;
consoleLog("info", "clicked");
return delay(2, function() {
consoleLog("info", "reset click state");
return anyClick = false;
});
});
return window.addEventListener("popstate", function(e) {
if (anyClick !== true) {
consoleLog("info", "Back clicked");
return window.dataLayer.push({
event: 'analyticsEvent',
eventCategory: 'test',
eventAction: 'test'
});
}
});
})(window, jQuery);
You need to use WebConfigurationManager.OpenWebConfiguration()
:
For Example:
Dim myConfiguration As Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
myConfiguration.ConnectionStrings.ConnectionStrings("myDatabaseName").ConnectionString = txtConnectionString.Text
myConfiguration.AppSettings.Settings.Item("myKey").Value = txtmyKey.Text
myConfiguration.Save()
I think you might also need to set AllowLocation in machine.config. This is a boolean value that indicates whether individual pages can be configured using the element. If the "allowLocation" is false, it cannot be configured in individual elements.
Finally, it makes a difference if you run your application in IIS and run your test sample from Visual Studio. The ASP.NET process identity is the IIS account, ASPNET or NETWORK SERVICES (depending on IIS version).
Might need to grant ASPNET or NETWORK SERVICES Modify access on the folder where web.config resides.
Since January 7th, 2019, it is possible: unlimited free private repositories on GitHub!
... But for up to three collaborators per private repository.
Nat Friedman just announced it by twitter:
Today(!) we’re thrilled to announce unlimited free private repos for all GitHub users, and a new simplified Enterprise offering:
"New year, new GitHub: Announcing unlimited free private repos and unified Enterprise offering"
For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free.
Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly.
Starting today, those scenarios, and many more, are possible on GitHub at no cost.Public repositories are still free (of course—no changes there) and include unlimited collaborators.
You can use find()
>>> s = 'http://www.domain.com/?s=some&two=20'
>>> s[:s.find('&')]
'http://www.domain.com/?s=some'
Of course, if there is a chance that the searched for text will not be present then you need to write more lengthy code:
pos = s.find('&')
if pos != -1:
s = s[:pos]
Whilst you can make some progress using code like this, more complex situations demand a true URL parser.
As I didn't find why does this behaviour happen I have used the following code:
float myTabLayoutSize = 360;
if (DeviceInfo.getWidthDP(this) >= myTabLayoutSize ){
tabLayout.setTabMode(TabLayout.MODE_FIXED);
} else {
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
}
Basically, I have to calculate manually the width of my tabLayout and then I set the Tab Mode depending on if the tabLayout fits in the device or not.
The reason why I get the size of the layout manually is because not all the tabs have the same width in Scrollable mode, and this could provoke that some names use 2 lines as it happened to me in the example.
You can generate a random number with the rand
method. The argument passed to the rand
method should be an integer
or a range
, and returns a corresponding random number within the range:
rand(9) # this generates a number between 0 to 8
rand(0 .. 9) # this generates a number between 0 to 9
rand(1 .. 50) # this generates a number between 1 to 50
#rand(m .. n) # m is the start of the number range, n is the end of number range
This will compile all *.c
files upon make
to executables without the .c
extension as in gcc program.c -o program
.
make
will automatically add any flags you add to CFLAGS
like CFLAGS = -g Wall
.
If you don't need any flags CFLAGS
can be left blank (as below) or omitted completely.
SOURCES = $(wildcard *.c)
EXECS = $(SOURCES:%.c=%)
CFLAGS =
all: $(EXECS)
In my case... with MySQL:
SELECT ... GROUP BY TIMESTAMPADD(HOUR, HOUR(columName), DATE(columName))
C# has a static constructor for this purpose.
static class YourClass
{
static YourClass()
{
// perform initialization here
}
}
From MSDN:
A static constructor is used to initialize any static data, or to perform a particular action that needs to be performed once only. It is called automatically before the first instance is created or any static members are referenced
.
You'll need to write sort of ObjectConverter
for this. This is doable if you have both the object which you want to convert and you know the target class to which you'd like to convert to. In this particular case you can get the target class by Field#getDeclaringClass()
.
You can find here an example of such an ObjectConverter
. It should give you the base idea. If you want more conversion possibilities, just add more methods to it with the desired argument and return type.
try this, it's work without Base64 ( that is included only in JDK 1.8 ), this code run also in the previous java version :)

Through a combination of the suggestions I got, I came up with this:
private void DrawLetter()
{
Graphics g = this.CreateGraphics();
float width = ((float)this.ClientRectangle.Width);
float height = ((float)this.ClientRectangle.Width);
float emSize = height;
Font font = new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular);
font = FindBestFitFont(g, letter.ToString(), font, this.ClientRectangle.Size);
SizeF size = g.MeasureString(letter.ToString(), font);
g.DrawString(letter, font, new SolidBrush(Color.Black), (width-size.Width)/2, 0);
}
private Font FindBestFitFont(Graphics g, String text, Font font, Size proposedSize)
{
// Compute actual size, shrink if needed
while (true)
{
SizeF size = g.MeasureString(text, font);
// It fits, back out
if (size.Height <= proposedSize.Height &&
size.Width <= proposedSize.Width) { return font; }
// Try a smaller font (90% of old size)
Font oldFont = font;
font = new Font(font.Name, (float)(font.Size * .9), font.Style);
oldFont.Dispose();
}
}
So far, this works flawlessly.
The only thing I would change is to move the FindBestFitFont() call to the OnResize() event so that I'm not calling it every time I draw a letter. It only needs to be called when the control size changes. I just included it in the function for completeness.
import json
with open('result.json', 'w') as fp:
json.dump(sample, fp)
This is an easier way to do it.
In the second line of code the file result.json
gets created and opened as the variable fp
.
In the third line your dict sample
gets written into the result.json
!
If you want the field to always be hidden, use the following:
class MyForm(forms.Form):
hidden_input = forms.CharField(widget=forms.HiddenInput(), initial="value")
If you want the field to be conditionally hidden, you can do the following:
form = MyForm()
if condition:
form.fields["field_name"].widget = forms.HiddenInput()
form.fields["field_name"].initial = "value"
Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n
will work.
If you use anything else you will cause issues with cut and paste on Windows platforms.
The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n
linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.
Interestingly, in spite of the Unix line end convention being \n
, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n
. Yes, it may not make a lot of sense, but that's history and evolving standards for you!
Add an attribute colspan
(abbriviation for 'column span') in your top cell (<td>
) and set its value to 2.
Your table should resembles the following;
<table>
<tr>
<td colspan = "2">
<!-- Merged Columns -->
</td>
</tr>
<tr>
<td>
<!-- Column 1 -->
</td>
<td>
<!-- Column 2 -->
</td>
</tr>
</table>

Lots of outdated answers to this question. As of Swift 2+ the Swift Standard Library contains the readline() function. It will return an Optional but it will only be nil if EOF has been reached, which will not happen when getting input from the keyboard so it can safely be unwrapped by force in those scenarios. If the user does not enter anything its (unwrapped) value will be an empty string. Here's a small utility function that uses recursion to prompt the user until at least one character has been entered:
func prompt(message: String) -> String {
print(message)
let input: String = readLine()!
if input == "" {
return prompt(message: message)
} else {
return input
}
}
let input = prompt(message: "Enter something!")
print("You entered \(input)")
Note that using optional binding (if let input = readLine()) to check if something was entered as proposed in other answers will not have the desired effect, as it will never be nil and at least "" when accepting keyboard input.
This will not work in a Playground or any other environment where you does not have access to the command prompt. It seems to have issues in the command-line REPL as well.
CREATE VIEW MyView AS
SELECT Column, Value FROM Table;
SELECT Column FROM MyView WHERE Value = 1;
Is the proper solution in MySQL, some other SQLs let you define Views more exactly.
Note: Unless the View is very complicated, MySQL will optimize this just fine.
If you do
.headers ON
you will get the desired result.
Yes, Range :
The range form of the for loop iterates over a slice or map.
When ranging over a slice, two values are returned for each iteration. The first is the index, and the second is a copy of the element at that index.
Example :
package main
import "fmt"
var pow = []int{1, 2, 4, 8, 16, 32, 64, 128}
func main() {
for i, v := range pow {
fmt.Printf("2**%d = %d\n", i, v)
}
for i := range pow {
pow[i] = 1 << uint(i) // == 2**i
}
for _, value := range pow {
fmt.Printf("%d\n", value)
}
}
var elem = $('#some-id');
elem.mouseover(function () {
// Some code here
}).mouseout(function (event) {
var e = event.toElement || event.relatedTarget;
if (elem.has(e).length > 0) return;
// Some code here
});
You can add an undecorated JDialog like this:
import java.awt.event.*;
import javax.swing.*;
public class TestSwing {
public static void main(String[] args) throws Exception {
JFrame frame = new JFrame("Parent");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(800, 600);
frame.setVisible(true);
final JDialog dialog = new JDialog(frame, "Child", true);
dialog.setSize(300, 200);
dialog.setLocationRelativeTo(frame);
JButton button = new JButton("Button");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
dialog.dispose();
}
});
dialog.add(button);
dialog.setUndecorated(true);
dialog.setVisible(true);
}
}
I've faced the exactly same problem but I've fixed it with another approache.
Using Ubuntu 18.04, first disable systemd-resolved
service.
sudo systemctl disable systemd-resolved.service
Stop the service
sudo systemctl stop systemd-resolved.service
Then, remove the link to /run/systemd/resolve/stub-resolv.conf
in /etc/resolv.conf
sudo rm /etc/resolv.conf
Add a manually created resolv.conf
in /etc/
sudo vim /etc/resolv.conf
Add your prefered DNS server there
nameserver 208.67.222.222
I've tested this with success.
If you're behind a corporate proxy, try this setting for npm with your company's proxy:

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.
To answer your specific questions:
Alternatively (I'd say preferably), you can do it like this:
$(function () {
$("div.class, div.secondclass").click(function(){
//Doo something
});
});
It happens that none of the above methods work. Key binding is proper, but tool tip simply doesn't show in any case, neither as completion help or on demand.
To fix it just go to Tools\Text Editor\C# (or all languages) and check the 'Parameter Information'. Now it should work
Probably the easiest way would be use this app Hosts Editor . You need to have root
This is the post I read from apple Swift blog, might be helpful:
If you write a Swift app you can trust that your app will work well into the future. In fact, you can target back to OS X Mavericks or iOS 7 with that same app. This is possible because Xcode embeds a small Swift runtime library within your app's bundle. Because the library is embedded, your app uses a consistent version of Swift that runs on past, present, and future OS releases.
While your app's runtime compatibility is ensured, the Swift language itself will continue to evolve, and the binary interface will also change. To be safe, all components of your app should be built with the same version of Xcode and the Swift compiler to ensure that they work together.
This means that frameworks need to be managed carefully. For instance, if your project uses frameworks to share code with an embedded extension, you will want to build the frameworks, app, and extensions together. It would be dangerous to rely upon binary frameworks that use Swift — especially from third parties. As Swift changes, those frameworks will be incompatible with the rest of your app. When the binary interface stabilizes in a year or two, the Swift runtime will become part of the host OS and this limitation will no longer exist.
jQuery.contents()
can be used with jQuery.filter
to find all child text nodes. With a little twist, you can find grandchildren text nodes as well. No recursion required:

return this.nodeType === Node.TEXT_NODE;_x000D_

A very easy kind of event you can wait for is the ManualResetEvent
, and even better, the ManualResetEventSlim
.
They have a WaitOne()
method that does exactly that. You can wait forever, or set a timeout, or a "cancellation token" which is a way for you to decide to stop waiting for the event (if you want to cancel your work, or your app is asked to exit).
You fire them calling Set()
.
Here is the doc.
If you just want to know whether the certificate has expired (or will do so within the next N seconds), the -checkend <seconds>
option to openssl x509
will tell you:
if openssl x509 -checkend 86400 -noout -in file.pem
then
echo "Certificate is good for another day!"
else
echo "Certificate has expired or will do so within 24 hours!"
echo "(or is invalid/not found)"
fi
This saves having to do date/time comparisons yourself.
openssl
will return an exit code of 0
(zero) if the certificate has not expired and will not do so for the next 86400 seconds, in the example above. If the certificate will have expired or has already done so - or some other error like an invalid/nonexistent file - the return code is 1
.
(Of course, it assumes the time/date is set correctly)
Be aware that older versions of openssl have a bug which means if the time specified in checkend
is too large, 0 will always be returned (https://github.com/openssl/openssl/issues/6180).
It works by same principle of anonymous inner class where we can instantiate an interface without actually defining a class :
Ref: https://www.geeksforgeeks.org/anonymous-inner-class-java/
This should do the trick retrieving the params from the url:
constructor(private activatedRoute: ActivatedRoute) {
this.activatedRoute.queryParams.subscribe(params => {
let date = params['startdate'];
console.log(date); // Print the parameter to the console.
});
}
The local variable date should now contain the startdate parameter from the URL. The modules Router and Params can be removed (if not used somewhere else in the class).

When you perform a boolean comparison between two vectors in R, the "expectation" is that both vectors are of the same length, so that R can compare each corresponding element in turn.
R has a much loved (or hated) feature called recycling, whereby in many circumstances if you try to do something where R would normally expect objects to be of the same length, it will automatically extend, or recycle, the shorter object to force both objects to be of the same length.
If the longer object is a multiple of the shorter, this amounts to simply repeating the shorter object several times. Oftentimes R programmers will take advantage of this to do things more compactly and with less typing.
But if they are not multiples, R will worry that you may have made a mistake, and perhaps didn't mean to perform that comparison, hence the warning.
Explore yourself with the following code:
> x <- 1:3
> y <- c(1,2,4)
> x == y
[1] TRUE TRUE FALSE
> y1 <- c(y,y)
> x == y1
[1] TRUE TRUE FALSE TRUE TRUE FALSE
> y2 <- c(y,2)
> x == y2
[1] TRUE TRUE FALSE FALSE
Warning message:
In x == y2 :
longer object length is not a multiple of shorter object length
You can also do this:
//Get the current claims principal
var identity = (ClaimsPrincipal)Thread.CurrentPrincipal;
var claims = identity.Claims;
Update
To provide further explanation as per comments.
If you are creating users within your system as follows:
UserManager<applicationuser> userManager = new UserManager<applicationuser>(new UserStore<applicationuser>(new SecurityContext()));
ClaimsIdentity identity = userManager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
You should automatically have some Claims populated relating to you Identity.
To add customized claims after a user authenticates you can do this as follows:
var user = userManager.Find(userName, password);
identity.AddClaim(new Claim(ClaimTypes.Email, user.Email));
The claims can be read back out as Darin has answered above or as I have.
The claims are persisted when you call below passing the identity in:
AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = persistCookie }, identity);
use Jackson (https://github.com/FasterXML/jackson) from http://json.org/
HashMap<String,Object> result =
new ObjectMapper().readValue(<JSON_OBJECT>, HashMap.class);
If its working when you are using a browser and then passing on your username and password for the first time - then this means that once authentication is done Request header of your browser is set with required authentication values, which is then passed on each time a request is made to hosting server.
So start with inspecting Request Header (this could be done using Web Developers tools), Once you established whats required in header then you could pass this within your HttpWebRequest Header.
Example with Digest Authentication:

var digestResponse =
CalculateMd5Hash(string.Format("{0}:{1}:{2:00000000}:{3}:{4}:{5}", ha1, _nonce, _nc, _cnonce, _qop, ha2));
return string.Format("Digest username=\"{0}\", realm=\"{1}\", nonce=\"{2}\", uri=\"{3}\", " +
"algorithm=MD5, response=\"{4}\", qop={5}, nc={6:00000000}, cnonce=\"{7}\"",
_user, _realm, _nonce, dir, digestResponse, _qop, _nc, _cnonce);
}
public string GrabResponse(
string dir)
{
var url = _host + dir;
var uri = new Uri(url);
var request = (HttpWebRequest)WebRequest.Create(uri);
// If we've got a recent Auth header, re-use it!
if (!string.IsNullOrEmpty(_cnonce) &&
DateTime.Now.Subtract(_cnonceDate).TotalHours < 1.0)
{
request.Headers.Add("Authorization", GetDigestHeader(dir));
}
HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException ex)
{
// Try to fix a 401 exception by adding a Authorization header
if (ex.Response == null || ((HttpWebResponse)ex.Response).StatusCode != HttpStatusCode.Unauthorized)
throw;
var wwwAuthenticateHeader = ex.Response.Headers["WWW-Authenticate"];
_realm = GrabHeaderVar("realm", wwwAuthenticateHeader);
_nonce = GrabHeaderVar("nonce", wwwAuthenticateHeader);
_qop = GrabHeaderVar("qop", wwwAuthenticateHeader);
_nc = 0;
_cnonce = new Random().Next(123400, 9999999).ToString();
_cnonceDate = DateTime.Now;
var request2 = (HttpWebRequest)WebRequest.Create(uri);
request2.Headers.Add("Authorization", GetDigestHeader(dir));
response = (HttpWebResponse)request2.GetResponse();
}
var reader = new StreamReader(response.GetResponseStream());
return reader.ReadToEnd();
}
}
Then you could call it:
DigestAuthFixer digest = new DigestAuthFixer(domain, username, password);
string strReturn = digest.GrabResponse(dir);
if Url is: http://xyz.rss.com/folder/rss then domain: http://xyz.rss.com (domain part) dir: /folder/rss (rest of the url)
you could also return it as stream and use XmlDocument Load() method.
If you would like nicely auto-formatted code. Try CTRL + A + K + F. While holding down CTRL hit a, then k, then f.
Your code is doing a log
of a number that is less than or equal to zero. That's mathematically undefined, so Python's log
function raises an exception. Here's an example:
>>> from math import log
>>> log(-1)
Traceback (most recent call last):
File "<pyshell#59>", line 1, in <module>
log(-1)
ValueError: math domain error
Without knowing what your newtonRaphson2
function does, I'm not sure I can guess where the invalid x[2]
value is coming from, but hopefully this will lead you on the right track.
Just use not
:
if not your_variable:
print("your_variable is empty")
and for your 0 as string
use:
if your_variable == "0":
print("your_variable is 0 (string)")
combine them:
if not your_variable or your_variable == "0":
print("your_variable is empty")
Python is about simplicity, so is this answer :)
You can do :
1) javac -cp /path/to/jar/file Myprogram.java
2) java -cp .:/path/to/jar/file Myprogram
So, lets suppose your current working directory
in terminal is src/Report/
javac -cp src/external/myfile.jar Reporter.java
java -cp .:src/external/myfile.jar Reporter
Take a look here to setup Classpath
The following should work:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
->where('reservation_from', '<=', $to)
->get();
In Python, the name of the class refers to the class instance. Consider:
class A: pass
class B: pass
class C: pass
lst = [A, B, C]
# instantiate second class
b_instance = lst[1]()
print b_instance
LOG_LOCATION="/path/to/logs"
exec >> $LOG_LOCATION/mylogfile.log 2>&1
Since the inputs are empty and therefore invalid when instantiated, Angular correctly adds the ng-invalid
class.
A CSS rule you might try:
input.ng-dirty.ng-invalid {
color: red
}
Which basically states when the field has had something entered into it at some point since the page loaded and wasn't reset to pristine by $scope.formName.setPristine(true)
and something wasn't yet entered and it's invalid then the text turns red
.
Other useful classes for Angular forms (see input for future reference )
ng-valid-maxlength
- when ng-maxlength
passes
ng-valid-minlength
- when ng-minlength
passes
ng-valid-pattern
- when ng-pattern
passes
ng-dirty
- when the form has had something entered since the form loaded
ng-pristine
- when the form input has had nothing inserted since loaded (or it was reset via setPristine(true)
on the form)
ng-invalid
- when any validation fails (required
, minlength
, custom ones, etc)
Likewise there is also ng-invalid-<name>
for all these patterns and any custom ones created.
If you aren't going to upload this to the App Store, you can also use a private method of UIView.
@interface UIView(Private)
- (UIViewController *)_viewControllerForAncestor;
@end
// Later in the code
UIViewController *vc = [myView _viewControllerForAncestor];
Your Code is:
FROM
dbo.Employees
TO
exe.Employees
I tried with this query.
ALTER SCHEMA exe TRANSFER dbo.Employees
Just write create schema exe
and execute it
I faced the similar problem in no reason, i think it was caused by IDE(android studio). I have tried all of above solutions but not worked. Finally, in my own situation, i solved this problem by the following actions:
- Close the current project and remove it from the list of projects in android studio ,and reopen it by Open an existing Android Studio project
, then it may be worked. I hope that my experience will be useful for you.
There is the easiest method, using File::Slurp
module:
use File::Slurp;
my @lines = read_file("filename", chomp => 1); # will chomp() each line
If you need some validation for each line you can use grep
in front of read_file
.
For example, filter lines which contain only integers:
my @lines = grep { /^\d+$/ } read_file("filename", chomp => 1);
mongorestore
is the tool to use to import bson files that were dumped by mongodump
.
From the docs:
mongorestore takes the output from mongodump and restores it.
Example:
# On the server run dump, it will create 2 files per collection
# in ./dump directory:
# ./dump/my-collection.bson
# ./dump/my-collection.metadata.json
mongodump -h 127.0.0.1 -d my-db -c my-collection
# Locally, copy this structure and run restore.
# All collections from ./dump directory are picked up.
scp user@server:~/dump/**/* ./
mongorestore -h 127.0.0.1 -d my-db
Gentil Kiwi's answer is correct. He developed this mimikatz tool that is able to retrieve non-exportable private keys.
However, his instructions are outdated. You need:
Download the lastest release from https://github.com/gentilkiwi/mimikatz/releases
Run the cmd with admin rights in the same machine where the certificate was requested
Change to the mimikatz bin directory (Win32 or x64 version)
Run mimikatz
Follow the wiki instructions and the .pfx file (protected with password mimikatz) will be placed in the same folder of the mimikatz bin

1) Are you sure mod_rewrite module is enabled? Check phpinfo()
2) Your above rule assumes the URL starts with "folder". Is this correct? Did you acutally want to have folder in the URL? This would match a URL like:
/folder/thing -> /folder/thing.php
If you actually want
/thing -> /folder/thing.php
You need to drop the folder from the match expression.
I usually use this to route request to page without php (but yours should work which leads me to think that mod_rewrite may not be enabled):
RewriteRule ^([^/\.]+)/?$ $1.php [L,QSA]
3) Assuming you are declaring your rules in an .htaccess file, does your installation allow for setting Options (AllowOverride) overrides in .htaccess files? Some shared hosts do not.
When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.
You can create a simple reusable divider.
Create Divider:
public class DividerItemDecorator extends RecyclerView.ItemDecoration {
private Drawable mDivider;
public DividerItemDecorator(Drawable divider) {
mDivider = divider;
}
@Override
public void onDraw(Canvas canvas, RecyclerView parent, RecyclerView.State state) {
int dividerLeft = parent.getPaddingLeft();
int dividerRight = parent.getWidth() - parent.getPaddingRight();
int childCount = parent.getChildCount();
for (int i = 0; i < childCount; i++) {
View child = parent.getChildAt(i);
RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
int dividerTop = child.getBottom() + params.bottomMargin;
int dividerBottom = dividerTop + mDivider.getIntrinsicHeight();
mDivider.setBounds(dividerLeft, dividerTop, dividerRight, dividerBottom);
mDivider.draw(canvas);
}
}
}
Create Divider Line: divider.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size
android:width="1dp"
android:height="1dp" />
<solid android:color="@color/grey_300" />
</shape>
Add divider to your Recyclerview:
RecyclerView.ItemDecoration dividerItemDecoration = new DividerItemDecorator(ContextCompat.getDrawable(context, R.drawable.divider));
recyclerView.addItemDecoration(dividerItemDecoration);
To remove divider for the last item:
To prevent divider drawing for the last item you have to change this line.
for (int i = 0; i < childCount; i++)
To
for (int i = 0; i < childCount-1; i++)
Your final implementation should be like this:
public class DividerItemDecorator extends RecyclerView.ItemDecoration {
private Drawable mDivider;
public DividerItemDecorator(Drawable divider) {
mDivider = divider;
}
@Override
public void onDraw(Canvas canvas, RecyclerView parent, RecyclerView.State state) {
int dividerLeft = parent.getPaddingLeft();
int dividerRight = parent.getWidth() - parent.getPaddingRight();
int childCount = parent.getChildCount();
for (int i = 0; i < childCount - 1; i++) {
View child = parent.getChildAt(i);
RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
int dividerTop = child.getBottom() + params.bottomMargin;
int dividerBottom = dividerTop + mDivider.getIntrinsicHeight();
mDivider.setBounds(dividerLeft, dividerTop, dividerRight, dividerBottom);
mDivider.draw(canvas);
}
}
}
Hope it helps:)
Insert a column, for instance a new A column. Then use this function;
="k"&B1
and copy it down.
Then you can hide the new column A if you need too.
try this command, xcopy c:\ (file or directory path) F:\ /e. If you want more details refer this site [[http://www.computerhope.com/xcopyhlp.htm]]
You can use jquery animate function for that.
$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
duration: 8000,
easing: 'linear',
step: function () {
$('.code').html(Math.floor(this.countNum) );
},
complete: function () {
$('.code').html(this.countNum);
//alert('finished');
}
});
Here's the original article
A helper method would alleviate this extra overhead, and give you the same jQuery feel.
function Deferred() {
let resolve;
let reject;
const promise = new Promise((res, rej) => {
resolve = res;
reject = rej;
});
return { promise, resolve, reject };
}
Usage would be
const { promise, resolve, reject } = Deferred();
displayConfirmationDialog({
confirm: resolve,
cancel: reject
});
return promise;
Which is similar to jQuery
const dfd = $.Deferred();
displayConfirmationDialog({
confirm: dfd.resolve,
cancel: dfd.reject
});
return dfd.promise();
Although, in a use case this simple, native syntax is fine
return new Promise((resolve, reject) => {
displayConfirmationDialog({
confirm: resolve,
cancel: reject
});
});

You are entering a null value to nextInt, it will fail if you give a null value...
i have added a null check to the piece of code
Try this code:
import java.util.Scanner;
class MyClass
{
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
int eid,sid;
String ename;
System.out.println("Enter Employeeid:");
eid=(scanner.nextInt());
System.out.println("Enter EmployeeName:");
ename=(scanner.next());
System.out.println("Enter SupervisiorId:");
if(scanner.nextLine()!=null&&scanner.nextLine()!=""){//null check
sid=scanner.nextInt();
}//null check
}
}
If you don't care too much about performance and want to use the straightforward way, you can use either DIV
or IDIV
.
DIV
or IDIV
takes only one operand where it divides
a certain register with this operand, the operand can
be register or memory location only.
When operand is a byte: AL = AL / operand, AH = remainder (modulus).
Ex:
MOV AL,31h ; Al = 31h
DIV BL ; Al (quotient)= 08h, Ah(remainder)= 01h
when operand is a word: AX = (AX) / operand, DX = remainder (modulus).
Ex:
MOV AX,9031h ; Ax = 9031h
DIV BX ; Ax=1808h & Dx(remainder)= 01h
There is not a Google Chrome extension comparable to Selenium IDE.
Scirocco is only a partial (and reportedly unreliable) implementation.
There is another plugin, the Bug Buster Test Recorder, but it only works with their service. I don't know it's effectiveness.
Sahi and TestComplete can also record, but neither are free, and are not browser plugins.
iMacros is a plugin that allows record and playback, but is not geared towards testing, and is not compatible with Selenium.
It sounds like there is a demand for a tool like this, and Firefox is becoming unsupported by Selenium. So, while I know Stack Overflow isn't the forum for this, anyone interested in helping make it happen, let me know.
I'd be interested in what the limitations are and why it hasn't been done. Is it just that the official Selenium team doesn't want to support it, or is there a technical limitation?
The first one. Those file paths are relative from where your .gitignore file is.
Grep the folder tree's *.vcxproj
files. Replace <WindowsTargetPlatformVersion>8.1</WindowsTargetPlatformVersion>
with <WindowsTargetPlatformVersion>10.0</WindowsTargetPlatformVersion>
or whatever SDK version you get when you update one of the projects.
Use rgba()
:
.transparent {
background-color: rgba(255,255,255,0.5);
}
This will give you 50% opacity while the content of the box will continue to have 100% opacity.
If you use opacity:0.5
, the content will be faded as well as the background. Hence do not use it.
There is no concept of folders or directories in S3. You can create file names like "abc/xys/uvw/123.jpg"
, which many S3 access tools like S3Fox
show like a directory structure, but it's actually just a single file in a bucket.
The Set
interface does not provide any ordering guarantees.
Its sub-interface SortedSet
represents a set that is sorted according to some criterion. In Java 6, there are two standard containers that implement SortedSet
. They are TreeSet
and ConcurrentSkipListSet
.
In addition to the SortedSet
interface, there is also the LinkedHashSet
class. It remembers the order in which the elements were inserted into the set, and returns its elements in that order.
<h1>{title}</h1>
<div>{username}</div>
if (($text = file_get_contents("file.html")) === false) {
$text = "";
}
$text = str_replace("{title}", "Title Here", $text);
$text = str_replace("{username}", "Username Here", $text);
then you can echo $text as string
Without doubt the easiest way, also compatible with Color Set Assets:
Swift:
view.setValue(NSColor.white, forKey: "backgroundColor")
Objective-C:
[view setValue: NSColor.whiteColor forKey: "backgroundColor"];
Interface Builder:
Add a user defined attribute backgroundColor
in the interface builder, of type NSColor
.
You don't need Lodash or Ramda or any other extra dependency.
Just use the ES6 find() function in a functional way:
savedViews.find(el => el.description === view)
Sometimes you need to use 3rd-party libraries to get all the goodies that come with them. However, generally speaking, try avoiding dependencies when you don't need them. Dependencies can:
Use jQuery:
Set Parent Height = Child offsetHeight.
$(document).ready(function() {
$(parent).css("height", $(child).attr("offsetHeight"));
}
Django needs your application-specific settings. Since it is already inside your manage.py
, just use that. The faster, but perhaps temporary, solution is:
python manage.py shell

From the JavaDocs for ResourceBundle.getBundle(String baseName)
:
baseName
- the base name of the resource bundle, a fully qualified class name
What this means in plain English is that the resource bundle must be on the classpath and that baseName
should be the package containing the bundle plus the bundle name, mybundle
in your case.
Leave off the extension and any locale that forms part of the bundle name, the JVM will sort that for you according to default locale - see the docs on java.util.ResourceBundle for more info.
Just generate migration:
rails g migration change_column_to_new_from_table_name
Update migration like this:
class ClassName < ActiveRecord::Migration
change_table :table_name do |table|
table.change :column_name, :data_type
end
end
and finally
rake db:migrate
<head>
<link rel="shortcut icon" href="favicon.ico">
</head>
Just tried this solution, we don't have to even write int.
int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };
Arrays.sort(twoDim, (a1,a2) -> a2[0] - a1[0]);
This thing will also work, it automatically detects the type of string.
It's a pretty old question, but for the sake of newcomers, this is how we can protect an IEnumerable<T>
from a null exception
. Another word, to create an empty instance of a variable of type IEnumerable<T>
public IEnumerable<T> MyPropertyName { get; set; } = Enumerable.Empty<T>();

TGrid is another option that people don't usually find in a google search. If the other grids you find don't suit your needs, you can give it a try, its free
the command posted by Milad and Sandy did not work for me with mstsc. i had to add TERMSRV to the /generic switch. i found this information here: https://gist.github.com/jdforsythe/48a022ee22c8ec912b7e
cmdkey /generic:TERMSRV/<server> /user:<username> /pass:<password>
i could then use mstsc /v:<server>

Maybe something like this:
import matplotlib.pyplot
import pylab
x = [1,2,3,4]
y = [3,4,8,6]
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
EDIT:
Let me see if I understand you correctly now:
You have:
test1 | test2 | test3
test3 | 1 | 0 | 1
test4 | 0 | 1 | 0
test5 | 1 | 1 | 0
Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.
Let's say you results are stored in a 2-D list:
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
We want to transform them into two variables so we are able to plot them.
And I believe this code will give you what you are looking for:
import matplotlib
import pylab
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
x = []
y = []
for ind_1, sublist in enumerate(results):
for ind_2, ele in enumerate(sublist):
if ele == 1:
x.append(ind_1)
y.append(ind_2)
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
Notice that I do need to import pylab
, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.
Yes you can.
Multiple document ready sections are particularly useful if you have other modules haging off the same page that use it. With the old window.onload=func
declaration, every time you specified a function to be called, it replaced the old.
Now all functions specified are queued/stacked (can someone confirm?) regardless of which document ready section they are specified in.
Do not use forward slashes at the beginning of path components, except when refering to the root directory:
os.path.join('/home/build/test/sandboxes', todaystr, 'new_sandbox')
see also: http://docs.python.org/library/os.path.html#os.path.join
Query all users and filter by the list from your text file:
$Users = Get-Content 'C:\scripts\Users.txt'
Get-ADUser -Filter '*' -Properties DisplayName,Office |
Where-Object { $Users -contains $_.SamAccountName } |
Select-Object DisplayName, Office |
Export-Csv 'C:\path\to\your.csv' -NoType
Get-ADUser -Filter '*'
returns all AD user accounts. This stream of user objects is then piped into a Where-Object
filter, which checks for each object if its SamAccountName
property is contained in the user list from your input file ($Users
). Only objects with a matching account name are passed forward to the next step of the pipeline. The output can be limited by selecting the relevant properties before exporting the data.
You can further optimize the code by replacing the -contains
operator with hashtable lookups:
$Users = @{}
Get-Content 'C:\scripts\Users.txt' | ForEach-Object { $Users[$_] = $true }
Get-ADUser -Filter '*' -Properties DisplayName,Office |
Where-Object { $Users.ContainsKey($_.SamAccountName) } |
Select-Object DisplayName, Office |
Export-Csv 'C:\path\to\your.csv' -NoType
You can't depend on the file having a BOM. UTF-8 doesn't require it. And non-Unicode encodings don't even have a BOM. There are, however, other ways to detect the encoding.
BOM is 00 00 FE FF (for BE) or FF FE 00 00 (for LE).
But UTF-32 is easy to detect even without a BOM. This is because the Unicode code point range is restricted to U+10FFFF, and thus UTF-32 units always have the pattern 00 {00-10} xx xx (for BE) or xx xx {00-10} 00 (for LE). If the data has a length that's a multiple of 4, and follows one of these patterns, you can safely assume it's UTF-32. False positives are nearly impossible due to the rarity of 00 bytes in byte-oriented encodings.
No BOM, but you don't need one. ASCII can be easily identified by the lack of bytes in the 80-FF range.
BOM is EF BB BF. But you can't rely on this. Lots of UTF-8 files don't have a BOM, especially if they originated on non-Windows systems.
But you can safely assume that if a file validates as UTF-8, it is UTF-8. False positives are rare.
Specifically, given that the data is not ASCII, the false positive rate for a 2-byte sequence is only 3.9% (1920/49152). For a 7-byte sequence, it's less than 1%. For a 12-byte sequence, it's less than 0.1%. For a 24-byte sequence, it's less than 1 in a million.
BOM is FE FF (for BE) or FF FE (for LE). Note that the UTF-16LE BOM is found at the start of the UTF-32LE BOM, so check UTF-32 first.
If you happen to have a file that consists mainly of ISO-8859-1 characters, having half of the file's bytes be 00 would also be a strong indicator of UTF-16.
Otherwise, the only reliable way to recognize UTF-16 without a BOM is to look for surrogate pairs (D[8-B]xx D[C-F]xx), but non-BMP characters are too rarely-used to make this approach practical.
If your file starts with the bytes 3C 3F 78 6D 6C (i.e., the ASCII characters "<?xml"), then look for an encoding=
declaration. If present, then use that encoding. If absent, then assume UTF-8, which is the default XML encoding.
If you need to support EBCDIC, also look for the equivalent sequence 4C 6F A7 94 93.
In general, if you have a file format that contains an encoding declaration, then look for that declaration rather than trying to guess the encoding.
There are hundreds of other encodings, which require more effort to detect. I recommend trying Mozilla's charset detector or a .NET port of it.
If you've ruled out the UTF encodings, and don't have an encoding declaration or statistical detection that points to a different encoding, assume ISO-8859-1 or the closely related Windows-1252. (Note that the latest HTML standard requires a “ISO-8859-1” declaration to be interpreted as Windows-1252.) Being Windows' default code page for English (and other popular languages like Spanish, Portuguese, German, and French), it's the most commonly encountered encoding other than UTF-8.
SELECT SCHEMA_NAME
FROM INFORMATION_SCHEMA.SCHEMATA
WHERE SCHEMA_NAME = 'DBName'
If you just need to know if a db exists so you won't get an error when you try to create it, simply use (From here):
CREATE DATABASE IF NOT EXISTS DBName;
A String
instance allocates a certain amount of bytes in memory. Maybe you're looking at something like sizeof("Hello World")
which would return the number of bytes allocated by the datastructure itself?
In Java, there's usually no need for a sizeof
function, because we never allocate memory to store a data structure. We can have a look at the String.java
file for a rough estimation, and we see some 'int', some references and a char[]
. The Java language specification defines, that a char
ranges from 0 to 65535, so two bytes are sufficient to keep a single char in memory. But a JVM does not have to store one char in 2 bytes, it only has to guarantee, that the implementation of char
can hold values of the defines range.
So sizeof
really does not make any sense in Java. But, assuming that we have a large String and one char
allocates two bytes, then the memory footprint of a String
object is at least 2 * str.length()
in bytes.

It gives the same result as Cameron's answer.
You can change the font size in R Markdown with HTML code tags <font size="1"> your text </font>
. This code is added to the R Markdown document and will alter the output of the HTML output.
For example:
<font size="1"> This is my text number1</font> _x000D_
_x000D_
<font size="2"> This is my text number 2 </font>_x000D_
_x000D_
<font size="3"> This is my text number 3</font> _x000D_
_x000D_
<font size="4"> This is my text number 4</font> _x000D_
_x000D_
<font size="5"> This is my text number 5</font> _x000D_
_x000D_
<font size="6"> This is my text number 6</font>
_x000D_
to escape non-alphanumeric characters of string variables, including dots, you could use re.escape
:
import re
expression = 'whatever.v1.dfc'
escaped_expression = re.escape(expression)
print(escaped_expression)
output:
whatever\.v1\.dfc
you can use the escaped expression to find/match the string literally.
int size = new FileInfo( filePath ).Length / 1024;
string humanKBSize = string.Format( "{0} KB", size );
string humanMBSize = string.Format( "{0} MB", size / 1024 );
string humanGBSize = string.Format( "{0} GB", size / 1024 / 1024 );
For a long time, CMake had the add_definitions
command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options).
An example using the new add_compile_definitions:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION})
add_compile_definitions(WITH_OPENCV2)
Or:
add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2)
The good part about this is that it circumvents the shabby trickery CMake has in place for add_definitions
. CMake is such a shabby system, but they are finally finding some sanity.
Find more explanation on which commands to use for compiler flags here: https://cmake.org/cmake/help/latest/command/add_definitions.html
Likewise, you can do this per-target as explained in Jim Hunziker's answer.
just select '0' as the value for the desired column
For me only this worked: I had to explicitly set the value of package to the parent directory, and add the parent directory to sys.path
from os import path
import sys
if __package__ is None:
sys.path.append( path.dirname( path.dirname( path.abspath(__file__) ) ) )
__package__= "myparent"
from .subdir import something # the . can now be resolved
I can now directly run my script with python myscript.py
.

Like Jessa Flint above, I didn't want to manually edit .vs\config\applicationhost.config because I wanted the changes to persist in source control. I also didn't want to have a separate batch file. I'm using VS 2015.
Project Properties?Build Events?Pre-build event command line:
::The following configures IIS Express to bind to any address at the specified port
::remove binding if it already exists
"%programfiles%\IIS Express\appcmd.exe" set site "MySolution.Web" /-bindings.[protocol='http',bindingInformation='*:1167:'] /apphostconfig:"$(SolutionDir).vs\config\applicationhost.config"
::add the binding
"%programfiles%\IIS Express\appcmd.exe" set site "MySolution.Web" /+bindings.[protocol='http',bindingInformation='*:1167:'] /apphostconfig:"$(SolutionDir).vs\config\applicationhost.config"
Just make sure you change the port number to your desired port.
Quick answer, this eval work:
eval('var obj = {"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}')
With "thousands of rows" your best bet would obviously be to do server side paging. When I looked into the different AngularJs table/grid options a while back there were three clear favourites:
All three are good, but implemented differently. Which one you pick will probably be more based on personal preference than anything else.
ng-grid is probably the most known due to its association with angular-ui, but I personally prefer ng-table, I really like their implementation and how you use it, and they have great documentation and examples available and actively being improved.
There are two options for this problem.
1) git rebase
2) git merge
Only diff with above both in case of merge, will have extra commit in history
1) git checkout branch(b1,b2,b3)
2) git rebase origin/master (In case of conflicts resolve locally by doing git rebase --continue)
3) git push
Alternatively, git merge option is similar fashion
1) git checkout "your_branch"(b1,b2,b3)
2) git merge master
3) git push
On a system with both Python 2 and 3 installed and with pip2
-installed Pillow failing to provide Image
, it is possible to install PIL for Python 2 in a way that will solve ImportError: No module named Image
:
easy_install-2.7 --user PIL
or
sudo easy_install-2.7 PIL
Given a list:
var list = new List<Child>()
{
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};
The query would look like:
var newList = list
.GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
.Select(y => new ConsolidatedChild()
{
FavoriteColor = y.Key.FavoriteColor,
Friend = y.Key.Friend,
School = y.Key.School,
Children = y.ToList()
}
);
Test code:
foreach(var item in newList)
{
Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
foreach(var child in item.Children)
{
Console.WriteLine("\t Name: {0}", child.Name);
}
}
Result:
School: School1 FavouriteColor: blue Friend: Bob
Name: John
Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
Name: Bob
Another solution:
If you have a static subclass in a non-static outer class, you can access the resources from within the subclass via static variables in the outer class, which you initialise on creation of the outer class. Like
public class Outerclass {
static String resource1
public onCreate() {
resource1 = getString(R.string.text);
}
public static class Innerclass {
public StringGetter (int num) {
return resource1;
}
}
}
I used it for the getPageTitle(int position) Function of the static FragmentPagerAdapter within my FragmentActivity which is useful because of I8N.
If you need to hyperlink Sheet1 to all or corresponding sheets, then use simple vba code. If you wish to create a radio button, then assign this macro to that button ex "Home Page".
Here is it:
Sub HomePage()
'
' HomePage Macro
'
' This is common code to go to sheet 1 if do not change name for Sheet1
'Sheets("Sheet1").Select
' OR
' You can write you sheet name here in case if its name changes
Sheets("Monthly Reports Home").Select

I'd consider also Apache Thrift http://thrift.apache.org/
It can bridge between several programming languages, is highly efficient and has support for async or sync calls. See full features here http://thrift.apache.org/docs/features/
The multi language can be useful for future plans, for example if you later want to do part of the computational task in C++ it's very easy to do add it to the mix using Thrift.
To resolve this problem, you just need to add the abs resource path to your project build file, just like below:
sourceSets {
main {
res.srcDirs = ['src/main/res','../../ActionBarSherlock/actionbarsherlock/res']
}
}
So, I again compile without any errors.
I had this problem on a client's pc in IE 11 with Java installed. It worked fine in Chrome, but wouldn't work in IE. After several days of TS, I just tried unchecking ActiveX Filtering in settings->safety. Now Java works fine.
I was looking for a solution for myself, since jQuery 1.9.1 and above have removed the $.browser
functionality. I came up with this little function that works for me.
It does need a global variable (I've called mine _browser) in order to check which browser it is. I've written a jsfiddle to illustrate how it can be used, of course it can be expanded for other browsers by just adding a test for _browser.foo, where foo is the name of the browser. I did just the popular ones.
_browser = {};
function detectBrowser() {
var uagent = navigator.userAgent.toLowerCase(),
match = '';
_browser.chrome = /webkit/.test(uagent) && /chrome/.test(uagent) &&
!/edge/.test(uagent);
_browser.firefox = /mozilla/.test(uagent) && /firefox/.test(uagent);
_browser.msie = /msie/.test(uagent) || /trident/.test(uagent) ||
/edge/.test(uagent);
_browser.safari = /safari/.test(uagent) && /applewebkit/.test(uagent) &&
!/chrome/.test(uagent);
_browser.opr = /mozilla/.test(uagent) && /applewebkit/.test(uagent) &&
/chrome/.test(uagent) && /safari/.test(uagent) &&
/opr/.test(uagent);
_browser.version = '';
for (x in _browser) {
if (_browser[x]) {
match = uagent.match(
new RegExp("(" + (x === "msie" ? "msie|edge" : x) + ")( |\/)([0-9]+)")
);
if (match) {
_browser.version = match[3];
} else {
match = uagent.match(new RegExp("rv:([0-9]+)"));
_browser.version = match ? match[1] : "";
}
break;
}
}
_browser.opera = _browser.opr;
delete _browser.opr;
}
To check if the current browser is Opera you would do
if (_browser.opera) { // Opera specific code }
Edit Fixed the formatting, fixed the detection for IE11 and Opera/Chrome, changed to browserResult from result. Now the order of the _browser
keys doesn't matter. Updated jsFiddle link.
2015/08/11 Edit Added new testcase for Internet Explorer 12 (EDGE), fixed a small regexp problem. Updated jsFiddle link.
There may be some reasons like:
First try to connect from SQL Server Management Studio to your Remote database. If it connects it means problem is at the code side or at Visual Studio side if you are using the one.
Check the connectionstring, if the problem persists, check these two services:
Go in services.msc and search and start these two services.

I've installed MySQL using installer. In fact, there was no data directory alongside 'bin' directory.
So, I manually created the 'data' directory under "C:\Program Files\MySQL\MySQL Server 8.0". And it worked (changing the root password following steps suggested on https://dev.mysql.com/doc/mysql-windows-excerpt/5.7/en/resetting-permissions-windows.html.
You can use HttpPost, there are methods to add Header to the Request.
DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("header-name" , "header-value");
HttpResponse response = httpclient.execute(httpPost);
You should just use android studio for this process. It is just simpler. But first run this command in your react native app directory:
For Newer version of react-native(e.g. react native 0.49.0 & so on...)
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
For Older Version of react-native (0.49.0 & below)
react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
Then Use android studio to open the 'android' folder in you react native app directory, it will ask to upgrade gradle and some other stuff. go to build-> Generate signed APK and follow the instructions from there. It's really straight forward.
I think this is a bit cleaner pure CSS solution than Rens de Nobel's solution. Also this does not prevent from closing the dialog by clicking outside of it.
http://plnkr.co/edit/JCGVZQ?p=preview
Just add some CSS class to DIV container with .modal-dialog class to gain higher specificity than the bootstraps CSS, e.g. .centered.
HTML
<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel">
<div class="modal-dialog centered modal-lg">
<div class="modal-content">
...
</div>
</div>
</div>
And make this .modal-dialog.centered container fixed and properly positioned.
CSS
.modal .modal-dialog.centered {
position: fixed;
bottom: 50%;
right: 50%;
transform: translate(50%, 50%);
}
Or even simpler using flexbox.
CSS
.modal {
display: flex;
align-items: center;
justify-content: center;
}
This is an example of how I use this kind of thing:
HTML :
<input type="checkbox" id="ThisIsTheId" value="X" onchange="ThisIsTheFunction(this.id,this.checked)">
JAVASCRIPT :
function ThisIsTheFunction(temp,temp2) {
if(temp2 == true) {
document.getElementById(temp).style.visibility = "visible";
} else {
document.getElementById(temp).style.visibility = "hidden";
}
}
Throwing my version into the pile here:
import argparse
parser = argparse.ArgumentParser()
args = parser.parse_args()
if not vars(args):
parser.print_help()
parser.exit(1)
You may notice the parser.exit
- I mainly do it like that because it saves an import line if that was the only reason for sys
in the file...
Download MSBuild with the link from @Nicodemeus answer was OK, yet the installation was broken until I've added these keys into a register:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\MSBuild\ToolsVersions\12.0]
"VCTargetsPath11"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath11)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))"
"VCTargetsPath"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))"
Its very simple and single line query.
SELECT * FROM Table_Name ORDER BY RAND() LIMIT 0,10;
0..param_count
means "up to and including param_count".
0...param_count
means "up to, but not including param_count".
Range#map
does not return an Enumerable
, it actually maps it to an array. It's the same as Range#to_a
.
With git show
you can get a similar result. For look the commit (like it looks on git log
view) with the list of files included in, use:
git show --name-only [commit-id_A]^..[commit-id_B]
Where [commit-id_A]
is the initial commit and [commit-id_B]
is the last commit than you want to show.
Special attention with ^
symbol. If you don't put that, the commit-id_A information will not deploy.
You could try
lsb_release -a
which works on at least Debian and Ubuntu (and since it's LSB, it should surely be on most of the other mainstream distros at least). http://rpmfind.net/linux/RPM/sourceforge/l/ls/lsb/lsb_release-1.0-1.i386.html suggests it's been around quite a while.
We just ran into this ourselves when running dotnet ef database update

System.Data.SqlClient.SqlException (0x80131904): Cannot attach the file '.\OurDbName.mdf' as database 'OurDbName'.
Just wanted to express that here for other people who might be bumping into this. The "fix" is use absolute paths.

Updated answer
Here is how to change the box model used by the input/textarea/select elements so that they all behave the same way. You need to use the box-sizing
property which is implemented with a prefix for each browser
-ms-box-sizing:content-box;
-moz-box-sizing:content-box;
-webkit-box-sizing:content-box;
box-sizing:content-box;
This means that the 2px difference we mentioned earlier does not exist..
example at http://www.jsfiddle.net/gaby/WaxTS/5/
note: On IE it works from version 8 and upwards..
Original
if you reset their borders then the select
element will always be 2 pixels less than the input
elements..
Standard CSS3 rotate should work in IE9, but I believe you need to give it a vendor prefix, like so:
-ms-transform: rotate(10deg);
It is possible that it may not work in the beta version; if not, try downloading the current preview version (preview 7), which is a later revision that the beta. I don't have the beta version to test against, so I can't confirm whether it was in that version or not. The final release version is definitely slated to support it.
I can also confirm that the IE-specific filter
property has been dropped in IE9.
[Edit]
People have asked for some further documentation. As they say, this is quite limited, but I did find this page: http://css3please.com/ which is useful for testing various CSS3 features in all browsers.
But testing the rotate feature on this page in IE9 preview caused it to crash fairly spectacularly.
However I have done some independant tests using -ms-transform:rotate()
in IE9 in my own test pages, and it is working fine. So my conclusion is that the feature is implemented, but has got some bugs, possibly related to setting it dynamically.
Another useful reference point for which features are implemented in which browsers is www.canIuse.com -- see http://caniuse.com/#search=rotation
[EDIT]
Reviving this old answer because I recently found out about a hack called CSS Sandpaper which is relevant to the question and may make things easier.
The hack implements support for the standard CSS transform
for for old versions of IE. So now you can add the following to your CSS:
-sand-transform: rotate(10deg);
...and have it work in IE 6/7/8, without having to use the filter
syntax. (of course it still uses the filter syntax behind the scenes, but this makes it a lot easier to manage because it's using similar syntax to other browsers)

public class Permuations {
public static int totalPermutationsCount = 0;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("input string : ");
String inputString = sc.nextLine();
System.out.println("given input String ==> "+inputString+ " :: length is = "+inputString.length());
findPermuationsOfString(-1, inputString);
System.out.println("**************************************");
System.out.println("total permutation strings ==> "+totalPermutationsCount);

for (int i = currentIndex; i < inputString.length(); i++) {
//swap elements and call the findPermuationsOfString()
char[] carr = inputString.toCharArray();
char tmp = carr[currentIndex];
carr[currentIndex] = carr[i];
carr[i] = tmp;
inputString = new String(carr);
//System.out.println("chat At : current String ==> "+inputString.charAt(currentIndex));
if(currentIndex == inputString.length()-1) {
totalPermutationsCount++;
System.out.println("permuation string ==> "+inputString);
} else {
//System.out.println("in else block>>>>");
findPermuationsOfString(currentIndex, inputString);
char[] rarr = inputString.toCharArray();

carr[i] = carr[currentIndex];
carr[currentIndex] = rtmp;
inputString = new String(carr);

<table style="border: 5px solid black">

I have also come across the same issue and figuredout the issue here is the solution.
Lot of people assumes Eclipse and maven intergration is tough but its very eassy.
1) download the maven and unzip it in to your favorite directory.
Ex : C:\satyam\DEV_TOOLS\apache-maven-3.1.1
2) Set the environment variable for Maven(Hope every one knows where to go to set this)
In the system variable: Variable_name = M2_HOME Variable_Value =C:\satyam\DEV_TOOLS\apache-maven-3.1.1
Next in the same System Variable you will find the variable name called Path: just edit the path variable and add M2_HOME details like with the existing values.
%M2_HOME%/bin;
so in the second step now you are done setting the Maven stuff to your system.you need to cross check it whether your setting is correct or not, go to command prompt and type mvn--version it should disply the path of your Maven
3) Open the eclipse and go to Install new software and type M2E Plugin install and restart the Eclipse
with the above 3 steps you are done with Maven and Maven Plugin with eclipse
4) Maven is used .m2 folder to download all the jars, it will find in Ex: C:\Users\tempsakat.m2
under this folder one settings.xml file and one repository folder will be there
5) go to Windwo - preferences of your Eclipse and type Maven then select UserSettings from left menu then give the path of the settings.xml here .
now you are done...

I came up with this one, that supports anchor and image tags, and supports single and double quotes.
<[a|img]+\\s+(?:[^>]*?\\s+)?[src|href]+=[\"']([^\"']*)['\"]
So
<a href="/something.ext">click here</a>
Will match:
Match 1: /something.ext
And
<a href='/something.ext'>click here</a>
Will match:
Match 1: /something.ext
Same goes for img src attributes
Your example is correct but not very portable. There is also a slightly cleaner syntax that can be used (as pointed out by @namespace-sid, among others).
However, suppose the templated class is part of some library that is to be shared...
Should other versions of the templated class be compiled?
Is the library maintainer supposed to anticipate all possible templated uses of the class?
Add a third file that is the template implementation/instantiation file in your sources.
lib/foo.hpp
in/from library
#pragma once
template <typename T>
class foo
{
public:
void bar(const T&);
};
lib/foo.cpp
compiling this file directly just wastes compilation time
// Include guard here, just in case
#pragma once
#include "foo.hpp"
template <typename T>
void foo::bar(const T& arg)
{
// Do something with `arg`
}
foo.MyType.cpp
using the library, explicit template instantiation of foo<MyType>
// Consider adding "anti-guard" to make sure it's not included in other translation units
#if __INCLUDE_LEVEL__ != 0
#error "Don't include this file"
#endif
// Yes, we include the .cpp file
#include <lib/foo.cpp>
#include "MyType.hpp"
template class foo<MyType>;
Of course, you can have multiple implementations in the third file. Or you might want multiple implementation files, one for each type (or set of types) you'd like to use, for instance.
This setup should reduce compile times, especially for heavily used complicated templated code, because you're not recompiling the same header file in each translation unit. It also enables better detection of which code needs to be recompiled, by compilers and build scripts, reducing incremental build burden.
foo.declarations.hpp
needs to know about foo<MyType>
's public interface but not .cpp
sources
#pragma once
#include <lib/foo.hpp>
#include "MyType.hpp"
// Declare `temp`. Doesn't need to include `foo.cpp`
extern foo<MyType> temp;
examples.cpp
can reference local declaration but also doesn't recompile foo<MyType>
#include "foo.declarations.hpp"
MyType instance;
// Define `temp`. Doesn't need to include `foo.cpp`
foo<MyType> temp;
void example_1() {
// Use `temp`
temp.bar(instance);
}
void example_2() {
// Function local instance
foo<MyType> temp2;
// Use templated library function
temp2.bar(instance);
}
error.cpp
example that would work with pure header templates but doesn't here
#include <lib/foo.hpp>
// Causes compilation errors at link time since we never had the explicit instantiation:
// template class foo<int>;
// GCC linker gives an error: "undefined reference to `foo<int>::bar()'"
void linkerError()
{
foo<int> nonExplicitlyInstantiatedTemplate;
}
Note that most compilers/linters/code helpers won't detect this as an error, since there is no error according to C++ standard.
But when you go to link this translation unit into a complete executable, the linker won't find a defined version of foo<int>
.
I'll recommend reading this link https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html from SpringBoot docs about injecting external configs. They didn't only talk about retrieving from a properties file but also YAML and even JSON files. I found it helpful. I hope you do too.
My solution is this:
$tempDate = '2012-07-10';
echo date('l', strtotime( $tempDate));
Output is: Tuesday
$tempDate = '2012-07-10';
echo date('D', strtotime( $tempDate));
Output is: Tue

You could implement a showfile function which takes in parameters of the data returned from the WEBApi, and a filename for the file you are trying to download. What I did was create a separate browser service identifies the user's browser and then handles the rendering of the file based on the browser. For instance if the target browser is chrome on an ipad, you have to use javascripts FileReader object.
FileService.showFile = function (data, fileName) {
var blob = new Blob([data], { type: 'application/pdf' });
if (BrowserService.isIE()) {
window.navigator.msSaveOrOpenBlob(blob, fileName);
}
else if (BrowserService.isChromeIos()) {
loadFileBlobFileReader(window, blob, fileName);
}
else if (BrowserService.isIOS() || BrowserService.isAndroid()) {
var url = URL.createObjectURL(blob);
window.location.href = url;
window.document.title = fileName;
} else {
var url = URL.createObjectURL(blob);
loadReportBrowser(url, window,fileName);
}
}
function loadFileBrowser(url, window, fileName) {
var iframe = window.document.createElement('iframe');
iframe.src = url
iframe.width = '100%';
iframe.height = '100%';
iframe.style.border = 'none';
window.document.title = fileName;
window.document.body.appendChild(iframe)
window.document.body.style.margin = 0;
}
function loadFileBlobFileReader(window, blob,fileName) {
var reader = new FileReader();
reader.onload = function (e) {
var bdata = btoa(reader.result);
var datauri = 'data:application/pdf;base64,' + bdata;
window.location.href = datauri;
window.document.title = fileName;
}
reader.readAsBinaryString(blob);
}

You can structure your parameter data
Work with fake json api
struct Parameter: Encodable {
let token: String = "xxxxxxxxxx"
let data: Dictionary = [
"id": "personNickname",
"email": "internetEmail",
"gender": "personGender",
]
}
let parameters = Parameter()
AF.request("https://app.fakejson.com/q", method: .post, parameters: parameters).responseJSON { response in
print(response)
}
The best way to do this is in version 4.2+ which allows using of aggregation pipeline in the update document and the updateOne
, updateMany
or update
collection method. Note that the latter has been deprecated in most if not all languages drivers.
Version 4.2 also introduced the $set
pipeline stage operator which is an alias for $addFields
. I will use $set
here as it maps with what we are trying to achieve.
db.collection.<update method>(
{},
[
{"$set": {"name": { "$concat": ["$firstName", " ", "$lastName"]}}}
]
)
In 3.4+ you can use $addFields
and the $out
aggregation pipeline operators.
db.collection.aggregate(
[
{ "$addFields": {
"name": { "$concat": [ "$firstName", " ", "$lastName" ] }
}},
{ "$out": "collection" }
]
)
Note that this does not update your collection but instead replace the existing collection or create a new one. Also for update operations that require "type casting" you will need client side processing, and depending on the operation, you may need to use the find()
method instead of the .aggreate()
method.
The way we do this is by $project
ing our documents and use the $concat
string aggregation operator to return the concatenated string.
we From there, you then iterate the cursor and use the $set
update operator to add the new field to your documents using bulk operations for maximum efficiency.
var cursor = db.collection.aggregate([
{ "$project": {
"name": { "$concat": [ "$firstName", " ", "$lastName" ] }
}}
])
from this, you need to use the bulkWrite
method.
var requests = [];
cursor.forEach(document => {
requests.push( {
'updateOne': {
'filter': { '_id': document._id },
'update': { '$set': { 'name': document.name } }
}

if (requests.length === 500) {

From this version you need to use the now deprecated Bulk
API and its associated methods.
var bulk = db.collection.initializeUnorderedBulkOp();
var count = 0;
cursor.snapshot().forEach(function(document) {
bulk.find({ '_id': document._id }).updateOne( {
'$set': { 'name': document.name }
});
count++;
if(count%500 === 0) {
// Excecute per 500 operations and re-init
bulk.execute();
bulk = db.collection.initializeUnorderedBulkOp();
}
})
// clean up queues
if(count > 0) {
bulk.execute();
}
cursor["result"].forEach(function(document) {
db.collection.update(
{ "_id": document._id },
{ "$set": { "name": document.name } }
);
})
I've used code like this, which will cause Objects to stringify with unique strings:
Object.prototype.__defineGetter__('__id__', function () {
var gid = 0;
return function(){
var id = gid++;
this.__proto__ = {
__proto__: this.__proto__,
get __id__(){ return id }
};
return id;
}
}.call() );
Object.prototype.toString = function () {
return '[Object ' + this.__id__ + ']';
};
the __proto__
bits are to keep the __id__
getter from showing up in the object. this has been only tested in firefox.

<version>4.8.2</version>
<scope>test</scope>
</dependency>
into <dependencies> node.

Import your package.json
file into your server.js
or app.js
and then access package.json properties into server file.
var package = require('./package.json');
package variable contains all the data in package.json.

functional requirements are the main things that the user expects from the software for example if the application is a banking application that application should be able to create a new account, update the account, delete an account, etc. functional requirements are detailed and are specified in the system design
Non-functional requirement are not straight forward the requirement of the system rather it is related to usability( in some way ) for example for a banking application a major non-functional requirement will be available the application should be available 24/7 with no downtime if possible.
An easy way to write cron is to use the online cron generator It will generate the line for you. One thing to note is that if you wish to run it each day (not just weekdays) you need to highlight all the days.
String str = "Test Word";
if(str.indexOf(' ') != -1){
return true;
} else{
return false;
}
I am using React-Bootstrap. The onSelect trigger for dropdowns were not allowing me to pass data. Just the event. So remember you can just set any values as attributes and pick them up from the function using javascript. Picking up those attributes you set in that event target.
let currentTarget = event.target;
let currentId = currentTarget.getAttribute('data-id');
let currentValue = currentTarget.getAttribute('data-value');
It is Purely swift notation an working for me
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
var cellIdentifier:String = "CustomFields"
var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? CustomCell
if (cell == nil)
{
var nib:Array = NSBundle.mainBundle().loadNibNamed("CustomCell", owner: self, options: nil)
cell = nib[0] as? CustomCell
}
return cell!

As @Quentin and @Pointy pointed out in their comments, it's not a good idea to use parseInt()
because it is designed to convert a string to an integer. When you pass a decimal number to it, it first converts the number to a string, then casts it to an integer. I suggest you use Math.trunc()
, Math.floor()
, ~~num
, ~~v
, num | 0
, num << 0
, or num >> 0
depending on your needs.
This performance test demonstrates the difference in parseInt()
and Math.floor()
performance.
Also, this post explains the difference between the proposed methods.
You can try something like this:
long x = somevalue;
double y = Double.longBitsToDouble(x);
Try something like this:
#include <signal.h>
pid_t child_pid = -1 ; //Global
void kill_child(int sig)
{
kill(child_pid,SIGKILL);
}
int main(int argc, char *argv[])
{
signal(SIGALRM,(void (*)(int))kill_child);
child_pid = fork();
if (child_pid > 0) {
/*PARENT*/
alarm(30);
/*
* Do parent's tasks here.
*/
wait(NULL);
}
else if (child_pid == 0){
/*CHILD*/
/*
* Do child's tasks here.
*/
}
}
I find I rarely have need to use getCanonicalPath()
but, if given a File with a filename that is in DOS 8.3 format on Windows, such as the java.io.tmpdir
System property returns, then this method will return the "full" filename.
