BatchGetFileName Example

InstallShield 2024 » 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 BatchGetFileName and BatchSetFileName

* functions.

*

* This example script retrieves the fully qualified name of the

* default batch file, which initially is the Autoexec.bat file

* on the boot drive. It then makes C:\ISExampl.bat the default

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

* batch file again to show that it has been changed.
