Hi,
I have a main form that launch wmplayer application and play an audio
file.
I used Process.Start method to launch it.

My problem is that when the file is totally played , i don't know
how to close media player window programmatically?

Does anyone know how to do it?
Thanks in advance.

Post a WM_CLOSE to its main window.

Here is some example code to help you post the WM_CLOSE message:

[DllImport("Coredll.dll", EntryPoint="SendMessage")]
private static extern int SendMessage(IntPtr hWnd, UInt32 Msg, int wParam,
int lParam);

private const UInt32 WM_CLOSE = 16 ;

Process myProcess; // Create your new process

// Run the media player.

SendMessage(myProcess.MainWindowHandle, WM_CLOSE, 0, 0);

I Hope this helps.

Hi,

You can use FindWindow to get the handle of your window, check out

thanks for your help !
I resolved with this snippet
------------------------------------------------------
Dim nWnd As IntPtr
nWnd = GetForegroundWindow()
SendMessage(nWnd, WM_CLOSE, 0, 0)
------------------------------------------------------

i tried also with
------------------------------------------------------
Dim _ip As Integer = myProcess.MainWindowHandle()
SendMessage(_ip, WM_CLOSE, 0, 0)
------------------------------------------------------

but it seems that doesn't work.
Is there an explanation?
