- 2007/09/19 Disable ALT+TAB, CTRL+ESC, CTRL+ALT+DEL
If you wish to disable those key combinations while your application is running call SystemKeys. When you call SystemKeys, if Disable is True, the keys will be disabled, False otherwise.
Note: the code does NOT work under Win NT systems (XP, 2000)
procedure SystemKeys(Disable: Boolean) ;
var OldVal : LongInt;
begin
SystemParametersInfo(SPI_SCREENSAVERRUNNING, Word(Disable), @OldVal, 0) ;
end;
var OldVal : LongInt;
begin
SystemParametersInfo(SPI_SCREENSAVERRUNNING, Word(Disable), @OldVal, 0) ;
end;
