GetProfString Example

InstallShield 2016 » InstallScript Language Reference

Note • To call this function in a Basic MSI setup, you must first create a custom action for the entry-point function, execute the custom action in a sequence or as the result of a dialog's control event, and then build the release.

* InstallShield Example Script

*

* Demonstrates the functions AddProfString and GetProfString.

*

* This script adds a profile string to a file; then it

* retrieves and displays the string that was added.

*

* Note: The first time you run this script, it will create a

*       file named ISExampl.ini in the root of drive C. You

*       may delete that file when you have finished analyzing

*       this script.
