VB4: "Winoldap" and "Shell"

Hi all,

I wrote a program under VB4/Win95. The major purpose of this program is to call DELTREE.EXE and XCOPY32.EXE so it's quite a simple program.
However, after the program executed, another program "Winoldap" left in the memory (I check it my pressing Crtl+Alt+Del). It will left one "Winoldap" onces my program execute. The "Winoldap" let my PC refuse to reboot and I have to shut down the "Winoldap" before I can reboot it.
Could someone solve it or give me further suggestion?

And how can I know when the "SHELL" command finished?

Thanks.
Arthur.

Oldapp is started when you call DELTREE or XCOPY.

Ok put these 3 functions in the declarations:

Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long

Then where you call your Shell statement use:

dim pid as long
dim handle as long
' Start the shelled application:
pid = Shell("Deltree blah blah", 1) ' also try ,0
handle = OpenProcess(&H100000, 0, pid)
' Wait for the shelled application to finish:
ret& = WaitForSingleObject(handle,&HFFFFFFFF) ' wait to finish
ret& = CloseHandle(handle) ' this one closes the shell window

I don't know if this method works with 16bit Windows Applications though.

Thanks Idek1,

The SHELL window can be holded but the it won't automatically be closed after finished. The statements after the SHELL will only be run when I close the SHELL manually. Do you have any other suggestion?

I cannot think of why this would not close the shell window, as it actually does exactly this (closes it) when I run it on my machine.
