calling one .exe while running another .exe

I need some assistance as to a particular stumbling block....

Background info: I have two programs (program1 & program2) which are both executables. They have been developed using three forms each.

The problem: While I am operating program1.exe, I need to be able to call up a particular form in program2.exe. Currently I am able to call program2 using...
Shell(App.Path & "\program2.exe",vbNormalFocus)
...but I am not able to open it to form2 in program2! It will open to the main page but I need a different form to appear! That is my dilemna?

General questions: Is it possible to call a particular form in a different program other than the current program you are in?
If not, can I use a script or macro to automate the keystrokes of program2.exe? Could use any advice or code samples....

Thanks

What you need to do is pass some parameters through the Shell() function to the application you're opening.
Example:

<pre>Shell "myapp.exe showwindow2"

</pre>

Then, in your second appplication:

<pre>Sub Main()
Dim strTemp As String
strTemp = Command$
Select Case strTemp
Case "showwindow1"
Form1.Show
Case "showwindow2"
Form2.Show
Case "showwindow3"
Form3.Show
End Select
End Sub

</pre>

Good Luck
