In my application in access 1.1 there is a function called
waitshell, this function runs a ftp process and uses a function called GetModuleUsage.
This application was upgradring to access 95, i consulted
about this function in kernel32 but there isn't.
what can i do, to change this function if it is in a while

hMod=Shell("ftp -s:\\jiracheta\pat\valsoftp.bat",3)
while (GetModuleUsage(hMod)>0)

how can i get the seem functionality in access 95?

Thanks of lot,

Use CreateProcess() to kick off your process, and then watch for it with
WaitforSingleObject(hMod, 0) until WaitForSIngleObject returns WAIT_OBJECT_0, meaning the process terminated.

The STARTUPINFO and PROCESSINFO structures are a pain, but it should work for you.

I can't found any function called CreateProcess().

What about TaskFirst() and TaskNext() from ToolHelp.dll?

May I use these function in 32 bit and how?

do exist other way to do this?

NullTerminator answer was the correct method. But unless you see a sample working code you won't be able to do it. So I thought of giving you a sample routine. I have doen this in MS Access 97. It will work for Access 95 too.

Copy the code into a moudle and then call the subroutine from anywhere in your application.

This may make your life easier.

Good luck
