Hello all, This is my first post and first time here... really hope you can help me.

I have created an application that calls on external dll files. This works fine. What I would like to do is create a form (dialogue window) that pops up, not allowing the user to use the main form while the dll executes. The dll opens another program and sends data back to the original form.

I can create another form, open it etc.. but the code waits until it's closed b4 moving on to the actual execution of the dll...

Is there anyway I can open the dialogue that says "waiting for X program to finish" ?

I think you may have to disable any input controls on the main form, too. Users might still be able to move the pop-up window and make changes on the main form.

gg67, please don't respond to .NET questions with VB6 code. There's a legacy forum for VB6 discussion.

fartil3:
A thread can only do one thing at a time. Multiple forms can appear to be doing multiple things on the same thread because of the "message pump", a mechanism they use to receive input events. When you display a dialog, the calling form's message pump is suspended. That's why displaying a dialog "disables" the parent form. So I imagine your code looks like this:
What you'd /like/ is for DoStuff() to happen while the dialog is displayed. Unfortunately that's impossible with a single thread. You need to look into using something like the BackgroundWorker component to do your work on another thread while the dialog is displayed.
