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. |

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
}
