LongPathToQuote 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 LongPathToQuote function.

*

* This script calls LongPathToQuote to place double quotation

* marks around a long file name.  The result is displayed in

* in a dialog.  Then, LongPathToQuote is called again to

* remove the quotation marks and the result displayed in a

* dialog.
