Hacker’s Guide to Visual FoxPro
An irreverent look at how Visual FoxPro really works. Tells you the inside scoop on every command, function, property, event and method of Visual FoxPro.
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
