Hi experts,

I have one more question concerning the "GetModuleUsage" API function.

With help of the "Shell" and "GetModuleUsage" (= API function)

command I want to start several times a math software which reads input from a text file and does some very time consuming calculations with this input data.

So far my source code has the following structure:

Private Sub btnEndCommand_Click()

Dim i%

For i = 0 To 3

result = Shell("my_math_program.exe " , 6)

While GetModuleUsage(result) > 0

DoEvents

Wend

Next

End Sub

This attempt unfortunately has one very big setback:

In my VB sample procedure the user has to stop and start INTERACTIVELY

the single my_math_program sessions.

Is it possible to use "GetModuleUsage" in a "non-interactive-mode", too?

I would like to let us say 3 calculations being done during the night while

I am sleeping.

So I don't want to get up after each session and finish/start each session

by mouse click.

I want that each calculation session is started and finished AUTOMATICALLY,

without my interaction. So the second call of my_math_program should be

done after the first calculation is finished, the third call should be done

after the second calculation is finished, and so on.

Unfortunately one doesn't know the needed time for each calculation before,

so it makes no sense to start the calulation sessions in a certain time

interval.

What else could I try, If "GetModulUsage" is not the appropriate idea to

solve my problem?

If it is a help for you experts, I can send you this math program. It is

freeware so it can be freely distributed.

Any suggestions are highly appreciated.

Is you're math program an interactive application? I'm assuming it is not since it can run at night. In order for you're vb program to run you're math program several times, you can do a few things:

A) Create a loop in which:

1) you're math program gets executed

2) you're vb program checks for its termination using GetModuleUsage

3) you're vb program does some processing after the math program is done

4) go back to step 1

B) Instead of creating a closed loop with the above steps, place the above steps in a timer. Have the timer go off, say, every 5 minutes. Each time the timer event goes off, you could check the time from the system clock and therefore run the formentioned loop at predeterined times. Since you don't know what time to process, then it's better to maybe run the process every 5 minutes anyway.

QUESTION: Since you don't know what time to process the results of the math program, how do you determine when it's time run the vb program? All is dependent on that. The GetModuleUsage function is only usefull in determining when a certain application has terminated.

If you have any further questions don't hesitate to comment...

Hope this helps.
