Executing a remote program from a thread within a service

I have a C# client/server program that functions as expected. In attempts to get rid of the console window being displayed, I tried nesting the server code into a service with threads and such.

The problem occurs when the client tries to send across an "execute transaction", which executes a client specified program on the server. The remote process terminates but somehow doesn't let my program know, so the process hangs until I kill it. I'm exectuing the remote program by using the Process method:

Process myProcess;

myProcess = new Process();

myProcess = Process.Start("c:\\cycle.exe");

myProcess.WaitForExit(35000);

int errCk = myProcess.ExitCode;

myProcess.Close();

No matter how many milliseconds I use, the thread never receives the notice of termination of the remote process so the client hangs.

Is there any way I can kill the process after a specified interval and notify the thread that it died?

I am also open to eliminating the console window another way, outside of services and threads... if anyone has any suggestions.

That is a lot of effort if your only intention was to hide the console window from the user's view.

Try this:

...
using System.Runtime.InteropServices;
...

--------------------------------

And at the top of your class, put this:

[DllImport("user32.dll")]

publicstaticextern IntPtr FindWindow(string lpClassName,string lpWindowName);

[DllImport("user32.dll")]

staticexternbool ShowWindow(IntPtr hWnd, int nCmdShow);

--------------------------------

And within the Main function put this:

IntPtr hWnd = FindWindow(null, System.Windows.Forms.Application.ExecutablePath ); //put your console window caption here



if(hWnd != IntPtr.Zero)

{

   //Hide the window

   ShowWindow(hWnd, 0); // 0 = SW_HIDE

}

--------------------------------

If you wanted it to show again, you could do this:

if(hWnd != IntPtr.Zero)

{

   //Show window again

   ShowWindow(hWnd, 1); //1 = SW_SHOWNORMA

}

Thank you so much IR!!! This is exactly what I needed.
