SetDisplayEffect Example

InstallShield 2015 » InstallScript Language Reference

/*--------------------------------------------------------------*\

*

* InstallShield Example Script

*

* Demonstrates the SetDisplayEffect function.

*

* This script displays the same bitmap seven times, with a

* different effect each time.

*

* Note: In order for this script to run correctly, you must

*       set the constant BITMAP_FILE so that it references an

*       existing bitmap file on the target system.  The

*       constant BITMAP_ID can be any integer in this example

*       since the bitmap is not loaded from a DLL and there

*       are no other bitmaps on the screen.

*
