ListAddString 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 ListAddString function.

*

* ListAddString is called to add a string to the string list.

* Then it is called again to add another string after the

* first.  This string is also set as the current element.

* ListAddString is called for the third time to add a string

* before the current element.
