ExecuteProcess works in parallel?

[Joris]

I've got a process that basically just calls a bunch of other processes using ExecuteProcess(). Some of these processes depend on a previous process being completed, so it's important that the next ExecuteProcess() only starts when the previous one is finished. This doesn't seem to be the case however. Based on my observations the process do indeed start serially, but as they don't wait for the previous one to be finished the may be running in parallel which does result in some problematic results.

Anyone an idea how to get them to work serially?

I'm sorry, but you will really have to show us your code and describe in more detail what you are seeing and where.

ExecuteProcess calls from a single parent process run sequentially, one after another. Only when a previous ExecuteProcess function call finishes (returning the status of the process being called) does the next line of code get executed, so not really sure how you are reaching the conclusions that processes 'don't wait for the previous one to be finished'.

You're right, thanks.

The problem was a matter of stuff running in parallel, but it wasn't ExecuteProcess() itself that was the problem.
Some of these ExecuteProcess() commands run an ExecuteCommand() (i.e. running a *.bat-file) and others where trying to update the *.bat file while it was still processing (as TM1 doesn't know when a batch file is finished).

and others where trying to update the *.bat file while it was still processing (as TM1 doesn't know when a batch file is finished).

Do you use ExecuteCommand ? Check out the 2nd argument of that function.
