Debugging a called VB app

How do I debug a called VB app, with parameters being passed to it?

What I currently do is:
1. Make changes to VB;
2. Compile;
3. Call VB app from cmd line : App 123 abc;
4. Pull out hair;
5. Goto 1.

I have tried to assign a value to Command$ in IDE to facilitate debugging,but I get this error:
"Function call on left-hand side of assignment must return Variant or Object" :huh:

Go to the properties of the project while in the IDE and on the Make tab, enter in the Command Line Arguments.

Run the app and test.

Goto Project Properties and specify your command line parameters there.

Hope this helps!

Thanks!!! :-)
