Hi again David,
I think I've got to the bottom of my problem.
In my original test the issue was missing DLLs for my test executables.
On a windows machine this is generating pop-ups reporting this problem
and it seems that until these are cleared by 'oking' them there is no RC
returned. This means the process returns results as though it is still
running even though it hasn't started.
In the test I provided below the QUERY HANDLE will actually work as
expected and return a non zero error RC if you insert a small sleep
after the async start.
So it doesn't look there's any issue - sorry for suggesting there was.
On the other hand, I guess my question is if anyone knows if there's
anyway to start a process with a STAFCMD on win32 such that the process
creation (and failure) don't block with a pop-up if there's a missing
library for the command ?
