CreateProcess API not working in XP

[BobBooker]

I have an ActiveX EXE that contains the line of code below.
This program has worked quite happily on all Windows platforms until I installed it on XP Pro.

If CreateProcess(sNullStr, sCmdLine, ByVal pNull, ByVal pNull, _
APITRUE, 0&, pNull, sInitDir, start, proc) Then
......

I setup a test environment on the XP machine to see what was going on.
It fails at this point with the last API error message:

Run-time error '2147192417 (8004729f)':
The Parameter is incorrect
(not sure which parameter it is referring to)

I thought a Kernel32 API call would have been the same in XP/2000. Any ideas?

Regards
Bob

Well, it looks like this software program has similar problems. There is a solution listed, don't know if it will help, b/c it's for their program:

Unfortunately this doesn't relate to my problem. Thanks for looking.

Does anybody know of a difference between API calls in 2000 and XP?

Cheers

Can you post the API definitions you are using (CreateProcess, APITRUE, StartupInfo and ProcessInfo also)

A little bit more code would be a help too. How have you defined pNull?

It also seems to me that there is a byval missing in the function call

try

 CreateProcess(sNullStr, sCmdLine, ByVal pNull, ByVal pNull, _
APITRUE, 0&, [COLOR=red]ByVal[/color] pNull, sInitDir, start, proc)

Take Care
