How do I change the screen resolution when running a Delphi program without the change being permanent? Most win95 games with some advaned graphics (such as Red Alert, Outlaws etc.) do this when they run, and then restores the resolution when they terminate without messing up the desktop icons.

on your onformcreate procedure pass the API ChangeDisplaySettings

The ChangeDisplaySettings function changes the display settings to the specified graphics mode.

this API will allow you to set the pixels width and height etc.

then on the onformclose procedure do the same setting it back to what it was...

also checkout the delphi gaming components I forget the URL just search for them
they set the displaysettings and then set them back...

I have tried to use the ChangeDisplaySettings, but I'm not sure how to use the parameters. If I try to declare a variable of type DEVMODE or LPDEVMODE I get an error message.
