Question:
I have compiled a program as an .APP file. When I run this file from VFP 6, I would like to disable the close button until the user clicks on the Cancel button. I would also like to make the command window invisible or disabled when that .APP program is running. How do I do this?

Answer:
To disable the close button of the VFP window, execute the following command:

SCREEN.Closable = .F.

To enable the close button of the VFP window, execute the following command:

 SCREEN.Closable = .T.

To hide the command window, execute the following command:

HIDE WINDOW Command

To make the command window visible again, execute the following command:

 SHOW WINDOW Command
