handle to a window created by createprocess
-
I have used createProcess to run a process in a new window using CREATE_NEW_CONSOLE flag, Can any one help to get the handle to the console that i have created so as to close that window. code: CreateProcess(_T("\\windows\\ceplayer.exe"),_T("c:\\folder\\new.wmv"), NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &processInfo); Thanks in Advance

You can use EnumWindows() or EnumThreadWindows() to enumerate top level windows and GetWindowThreadProcessid() to check if specific window is created by your process (processInfo.dwProceddId)

Thanks Slavisa, I tried it. but it does nothing i donno why.. Could u please help me further with my code below: (I want to close the console that created within 3 seconds but it is not moving into that if part (bold)) CreateProcess(_T("\\windows\\iesample.exe"),imFullPath, NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &processInfo1); Sleep(3000); EnumWindows(&EnumProc,processInfo1.dwProcessId); BOOL CALLBACK EnumProc(HWND hwnd, LPARAM param) { DWORD id = GetWindowThreadProcessId(hwnd, NULL); if (id == (DWORD)param) { DestroyWindow(hwnd); return false; } return true; }

The return value of
GetWindowThreadProcessIdis the thread Id and not the process Id. If you want the process Id, use the second parameter like so.DWORD dwProcessId = 0;
GetWindowThreadProcessId(hwnd, &dwProcessId);
if (dwProcessId == (DWORD)param)«_Superman_» I love work. It gives me something to do between weekends.

I think it is better to send WM_CLOSE to the window instead of calling DestroyWindow().

I suspect you've to use
EnumThreadWindows[^], passing, asdwThreadIdargument, thedwThreadIdmember of thePROCESS_INFORMATIONstruct filled byCreateProcessfunction. It's just a guess: the test is up to you. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Friens i used GetWindowThreadProcessId(hwnd, &dwProcessId); and also PostMessage(hwnd,WM_CLOSE,0); but it is not moving into that if loop still if(dwprocessid == DWORD(param)) i could not figure it out what i need to do now or IS there any other way to get the handle of the window seeking ur help....

Well, since you just want to close the program you could use TerminateProcess(hProcess, 0);

I am sorry not exactly i want to close the process slavisa i need to close that window alone and should open the next command line say next.wmv in that place

A hammer is another option. :)
