There are many ways how apps can communicate. Some more, some less efficient.

For example. You can use Winsock component. One app can open a socket and listen to it. The other one then sends a message.

Btw... you cannot change Control's Property from another app directly. You can however use some APIs but is quite complicated.

You could modify the second app to that it uses the Command$ function to accept input parameters (in this case the name and password). You could then Shell the second app from the first.

Here's an example:

App2.exe contains

Private Sub Form_Load()

Text1.Text = Command$

End Sub

App1 does this

    Shell "C:\temp\app2.exe hi there"

When you do that, App2 will show up with hi there in text1.text

yeah this will work only when the app loads. what about after it loads? i want to do his when both the exes are loaded on to memory.
