multi-programs in VB6

[Sehnsucht]

Hello, I need a little help in a VB6 project of my own:

I'd like to know how to give hand back to a VB6 program "A" after it had given its hand to another VB6 program "B".

I use a "shell" instruction to launch program "B" from program "A" is there another instruction more usefull in this case or in general ?

Thanks in advance for your answers.

The Shell function operates asynchronously so when program "A" launches program "B", program "A" will continue on to the next instruction w/o waiting for program "B" to finish.

If this is what you need to happen then the Shell function should be fine for your implementation.

No, it's not really what I want.

To be more precise, I want to make program "A" a 'main-program' for three programs "B", "C" and "D"

In other words program "A" would be a 'Choose what sub-program you want to launch' program.

I'm not sure it will be clearer helping you to help me !

So how do you expect the main program and sub programs to interract with each other. I'm a little unclear as to what you need to happen.

What I need to happen...

- I launch my program "A" (a simple form with 3 buttons, one for each 'sub-program' or something like that)
- I click on one of the 3 buttons
- It launches the 'sub-program' associated to it
- I execute the 'sub-program' till its end
- And at the end it gives back the hand to the 'main-program' "A" which was like "in pause" during this time

I hope it can helps a little more !

You should be able to find an example in the following:

No need to keep the simple form "paused" - all you need to do is have it check for any of the 3 programs running and not do anything if it finds any. Effectively doing what you want to do, which, if I understand correctly, only allow one of the 3 apps to run at any given time.

So, click button A. Form checks for processes A,B,C running, doesn't find any and launches A. Click button B. Form finds process A running, does nothing.
