DialogSetInfo Example

InstallShield 2014 » InstallScript Language Reference

Edition: This information applies to the following project types:

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

*

* InstallShield Example Script

*

* Demonstrates the DialogSetInfo function.

*

* This script calls AskText twice.  On the first call the

* AskText dialog displays the default bitmap.  Then

* DialogSetInfo is called to specify an alternate bitmap;

* that bitmap is then displayed on the second call to AskText.

*

* Note: Before running this script, set the defined constant

*       FULL_BMP_PATH so that it references a bitmap file

*       included in the Support Files/Billboards view.
