Hackers Guide to Visual FoxPro 7.0

Activate Screen

By default, output from many commands goes to the active window. ACTIVATE SCREEN lets you direct it to the main Visual FoxPro window instead.

Usage

ACTIVATE SCREEN

When a user-defined window (including one containing a form) is active, issuing a command like DISPLAY MEMORY or ? sends the output to the window. That's not usually what you want. It sure isn't when we do it. Issue ACTIVATE SCREEN before the DISPLAY whatever or ?, and the output goes to the main window instead.

Example

DEFINE WINDOW Test AT 0,0 SIZE 10,100 ACTIVATE WINDOW Test * Now all output goes to window Test - prove it DISPLAY MEMORY * That's no good - try again ACTIVATE SCREEN DISPLAY MEMORY && much better RELEASE WINDOW Test && clean up
