GetExtents

InstallShield 2008 » InstallScript Language Reference

The GetExtents function retrieves the dimensions of a screen—in pixels. The width of the screen is returned in nvDx and the height is returned in nvDy. For example, a standard VGA monitor returns 640 in nvDx and 480 in nvDy.

Note

The screen dimensions of the target machine can be gotten natively through the Windows Installer service by using the ScreenX and ScreenY properties.
