StrToLower 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 StrToUpper and StrToLower functions.

*

* StrToUpper is called to convert the characters in szSource

* from lowercase to uppercase.

*

* StrToLower is then called to convert the uppercase

* characters to lowercase.
