Closing an Application Window

Hi Guys,
I am running an external app from my prog and on some systems, its window remains open after it has finished. I don't want this to happen, so my question is: How do i ensure that the app window is closed when it finishes?

Hehe, I just posted a similar question. What method are you using to run the external application?

This is the code i'm using

VB Code:

Public Function ExecCmd(cmdline$)
    Dim proc As PROCESS_INFORMATION
    Dim start As STARTUPINFO
    Dim ret&
    start.cb = Len(start)
    ret& = CreateProcessA(0&, cmdline$, 0&, 0&, 1&, NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)
    ret& = WaitForSingleObject(proc.hProcess, INFINITE)
    ret& = CloseHandle(proc.hProcess)
End Function
