ConfigGetFileName Example

InstallShield 2015 » 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 ConfigGetFileName and ConfigSetFileName

* functions.

*

* This example script retrieves the fully qualified name of the

* default configuration file, which initially is the Config.sys

* file on the boot drive.  It then makes C:\ISExampl.sys the

* default configuration file.  Finally, it retrieves the name of

* the default configuration file again to show that it has been

* changed.
