ConfigFileSave 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 ConfigFileLoad and ConfigFileSave functions.

*

* This example script shows how to open a configuration file

* for editing, how to create a backup of the original file,

* and how to save and close the edited file.

*

* To demonstrate how the file backup feature of ConfigFileSave

* prevents the overwriting of existing files, this script loads

* and saves two different configuration files.  The first file

* is backed up with a specific file name.  The second is backed

* up with a wildcard extension so that ConfigFileSave will

* generate a unique file extension consisting of three digits.

*

* Note: Before running this script, create two files

*       (ISExamp1.sys and ISExamp2.sys) in the root of

*       drive C.  For best effect, you should delete or

*       move any other files named ISExamp1.* or ISExamp2.*.
