Change the output type from *Console Application* to *Windows Application*. This can be done under *Project -&gt; Properties -&gt; Application* in Visual Studio:

Change your application type to a windows application. Your code will still run, but it will have no console window, nor standard windows window unless you create one.

Instead of `Console.Readline/key` you can use `new ManualResetEvent(false).WaitOne()` at last. This works well for me.


You can use user32.dll to achieve this without vscode

```c#
    class start
    {
        [DllImport(&quot;user32.dll&quot;)]
        static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
        static void Main()
        {
            IntPtr h = Process.GetCurrentProcess().MainWindowHandle;
            ShowWindow(h, 0);
            // Do the rest
```
This still flashes the screen but works good enough

the usings are
```
using System.Runtime.InteropServices;
using System.Diagnostics;
```
Note im still new to csharp and not perfect so feel free to comment and corrections!

Maybe you want to try [creating a Windows Service application][1]. It will be running in the background, without any UI.

Change the output type from ***Console Application*** to ***Windows Application***, 

And Instead of `Console.Readline/key` you can use `new ManualResetEvent(false).WaitOne()` at the end to keep the app running.


Amazon recently added the wonderful feature of tagging EC2 instances with key-value pairs to make management of large numbers of VMs a bit easier.

Is there some way to query these tags in the same way as some of the other user-set data? For example:

    $ curl http://169.254.169.254/latest/meta-data/placement/availability-zone
    us-east-1d

Is there some similar way to query the tags?


Query EC2 tags from within instance

I have a HTTPSystemDefinitions.cs file in C# project which basically describes the older windows ISAPI for consumption by managed code.

This includes the complete set of Structures relevant to the ISAPI not all or which are consumed by code.  On compilation all the field members of these structures are causing a warning like the following:- 

&gt;  Warning	Field &#39;UnionSquare.ISAPI.HTTP_FILTER_PREPROC_HEADERS.SetHeader&#39; is never assigned to, and will always have its default value null

or

&gt;  Warning	The field &#39;UnionSquare.ISAPI.HTTP_FILTER_PREPROC_HEADERS.HttpStatus&#39; is never used

Can these be disabled with `#pragma warning disable`?  If so what would the corresponding error numbers be?  If not is there anything else I can do?  Bear in mind that I only what to do this for this file, its important that I get see warnings like these coming from other files.

__Edit__

Example struct:-

    struct HTTP_FILTER_PREPROC_HEADERS
    {
        //
        //  For SF_NOTIFY_PREPROC_HEADERS, retrieves the specified header value.
        //  Header names should include the trailing &#39;:&#39;.  The special values
        //  &#39;method&#39;, &#39;url&#39; and &#39;version&#39; can be used to retrieve the individual
        //  portions of the request line
        //

        internal GetHeaderDelegate GetHeader;
        internal SetHeaderDelegate SetHeader;
        internal AddHeaderDelegate AddHeader;
            
        UInt32  HttpStatus;               // New in 4.0, status for SEND_RESPONSE
        UInt32  dwReserved;               // New in 4.0
    }

The thing is, I really don&#39;t want the console window to show up, but the solution should be running.
My point here is, I want to keep the application running in the background, without any window coming up.

How can I do that?

How can I add and read the value from **web.config** file?

Read Variable from Web.Config

If I run a process with `ShellExecute` (or in .net with `System.Diagnostics.Process.Start()`) the filename process to start doesn&#39;t need to be a full path.

If I want to start notepad, I can use

    Process.Start(&quot;notepad.exe&quot;);

instead of

    Process.Start(@&quot;c:\windows\system32\notepad.exe&quot;);

because the direcotry `c:\windows\system32` is part of the PATH environment variable.



how can I check if a file exists on the PATH without executing the process and without parsing the PATH variable?

    System.IO.File.Exists(&quot;notepad.exe&quot;); // returns false
    (new System.IO.FileInfo(&quot;notepad.exe&quot;)).Exists; // returns false

but I need something like this:

    System.IO.File.ExistsOnPath(&quot;notepad.exe&quot;); // should return true

and

    System.IO.File.GetFullPath(&quot;notepad.exe&quot;); // (like unix which cmd) should return
                                               // c:\windows\system32\notepad.exe

Is there a predefined class to do this task available in the BCL?

Check if an executable exists in the Windows path

I have a class which looks like this:

    public class Field
    {
        public string FieldName;
        public string FieldType;
    }

And an object `List&lt;Field&gt;` with values:

    {&quot;EmployeeID&quot;,&quot;int&quot;},
    {&quot;EmployeeName&quot;,&quot;String&quot;},
    {&quot;Designation&quot;,&quot;String&quot;}

I want to create a class that looks like this:

    Class DynamicClass
    {
        int EmployeeID,
        String EmployeeName,
        String Designation
    }

Is there any way to do this? 

I want this to be generated at runtime. I don&#39;t want a physical CS file residing in my filesystem.

Just curious as to how Skip &amp; Take are supposed to work. I&#39;m getting the results I want to see on the client side, but when I hook up the AnjLab SQL Profiler and look at the SQL that is being executed it looks as though it is querying for and returning the entire set of rows to the client.

Is it really returning all the rows then sorting and narrowing down stuff with LINQ on the client side?

I&#39;ve tried doing it with both Entity Framework and Linq to SQL; both appear to have the same behavior.

Not sure it makes any difference, but I&#39;m using C# in VWD 2010.

Any insight?

    public IEnumerable&lt;Store&gt; ListStores(Func&lt;Store, string&gt; sort, bool desc, int page, int pageSize, out int totalRecords)
    {
    	var context = new TectonicEntities();
    	totalRecords = context.Stores.Count();
    	int skipRows = (page - 1) * pageSize;
    	if (desc)
    		return context.Stores.OrderByDescending(sort).Skip(skipRows).Take(pageSize).ToList();
    	return context.Stores.OrderBy(sort).Skip(skipRows).Take(pageSize).ToList();
    }

Resulting SQL (Note: I&#39;m excluding the Count query):

    SELECT 
    [Extent1].[ID] AS [ID], 
    [Extent1].[Name] AS [Name], 
    [Extent1].[LegalName] AS [LegalName], 
    [Extent1].[YearEstablished] AS [YearEstablished], 
    [Extent1].[DiskPath] AS [DiskPath], 
    [Extent1].[URL] AS [URL], 
    [Extent1].[SecureURL] AS [SecureURL], 
    [Extent1].[UseSSL] AS [UseSSL]
    FROM [dbo].[tec_Stores] AS [Extent1]

After some further research, I found that the following works the way I would expect it to:

    public IEnumerable&lt;Store&gt; ListStores(Func&lt;Store, string&gt; sort, bool desc, int page, int pageSize, out int totalRecords)
    {
    	var context = new TectonicEntities();
    	totalRecords = context.Stores.Count();
    	int skipRows = (page - 1) * pageSize;			
    	var qry = from s in context.Stores orderby s.Name ascending select s;
    	return qry.Skip(skipRows).Take(pageSize);			
    }

Resulting SQL:

    SELECT TOP (3) 
    [Extent1].[ID] AS [ID], 
    [Extent1].[Name] AS [Name], 
    [Extent1].[LegalName] AS [LegalName], 
    [Extent1].[YearEstablished] AS [YearEstablished], 
    [Extent1].[DiskPath] AS [DiskPath], 
    [Extent1].[URL] AS [URL], 
    [Extent1].[SecureURL] AS [SecureURL], 
    [Extent1].[UseSSL] AS [UseSSL]
    FROM ( SELECT [Extent1].[ID] AS [ID], [Extent1].[Name] AS [Name], [Extent1].[LegalName] AS [LegalName], [Extent1].[YearEstablished] AS [YearEstablished], [Extent1].[DiskPath] AS [DiskPath], [Extent1].[URL] AS [URL], [Extent1].[SecureURL] AS [SecureURL], [Extent1].[UseSSL] AS [UseSSL], row_number() OVER (ORDER BY [Extent1].[Name] ASC) AS [row_number]
    	FROM [dbo].[tec_Stores] AS [Extent1]
    )  AS [Extent1]
    WHERE [Extent1].[row_number] &gt; 3
    ORDER BY [Extent1].[Name] ASC

I really like the way the first option works; Passing in a lambda expression for sort. Is there any way to accomplish the same thing in the LINQ to SQL orderby syntax?  I tried using qry.OrderBy(sort).Skip(skipRows).Take(pageSize), but that ended up giving me the same results as my first block of code. Leads me to believe my issues are somehow tied to OrderBy.

Had to wrap the incoming lambda function in Expression:

Entity Framework/Linq to SQL: Skip &amp; Take

To get stuck in straight away, a very basic example:

    using System;
    using System.Windows.Forms;
    
    class test
    { 
        static void Main()
        { 
            Console.WriteLine(&quot;test&quot;);
            MessageBox.Show(&quot;test&quot;);
        }
    }

If I compile this with default options (using csc at command line), as expected, it will compile to a console application. Also, because I imported `System.Windows.Forms`, it will also show a message box.

Now, if I use the option `/target:winexe`, which I think is the same as choosing `Windows Application` from within project options, as expected I will only see the Message Box and no console output.

(In fact, the moment it is launched from command line, I can issue the next command before the application has even completed).

So, my question is - I know that you can have &quot;windows&quot;/forms output from a console application, but is there anyway to show the console from a Windows application?

How do I show a console output/window in a forms application?

I&#39;d like to add a progress indicator to a command-line Java program.

For example, if I&#39;m using wget, it shows:

    71% [===========================&gt;           ] 358,756,352 51.2M/s  eta 3s

Is it possible to have a progress indicator that updates without adding a new line to the bottom?

Thanks.

I&#39;m on Mac, working on Android development from the terminal.  I have successfully created the [HelloWorld][1] project and now I&#39;m trying to run it from the command line in the Android emulator.  Which command runs the emulator for my HelloWorld project?

I already have the Android tools and platform-tools in my PATH.

**Edit:**

How do I tell the emulator to run my HelloWorld project from the command line?  I&#39;ve already built the project with ant.

Is there any way to delete the last character from the console, i.e. 

    Console.WriteLine(&quot;List: apple,pear,&quot;);
    // Somehow delete the last &#39;,&#39; character from the console.
    Console.WriteLine(&quot;.&quot;);
    // Now the console contains &quot;List: apple,pear.&quot;

Sure, I could create a string first then print that to the console, but I&#39;m just curious to see if I can delete characters directly from the console.

Is there a way to delete a character that has just been written using Console.WriteLine?

I am trying to create process on a remote machine using using System.Diagnostics.Process class.
I am able to create a process. But the problem is, creating a service is take a long time and console window is displayed.
Another annoying thing is the console window is displayed on top of my windows form and i cant do any other operations on that form.
I have set all properties like `CreateNoWindow = true`, 

    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden

but still it shows the console window. even i have redirected output and errors to seperate stream but no luck.

Is there any other way to hide the Console window? Please help me out .

Here is the part of my code i used to execute sc command.

    Process proc = new Process();
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = true;
    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    proc.StartInfo.FileName = &quot;sc&quot;;
    proc.StartInfo.Arguments = string.Format(@&quot;\\SYS25 create MySvc binPath= C:\mysvc.exe&quot;);
    proc.StartInfo.RedirectStandardError = false;
    proc.StartInfo.RedirectStandardOutput = false;
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = true;
    proc.Start();
    proc.WaitForExit();
