BatchFileLoad 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 BatchFileLoad and BatchFileSave functions.

*

* This example script shows how to open a batch 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 BatchFileSave

* prevents the overwriting of existing files, this script loads

* and saves two different batch files.  The first batch file is

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

* with a wildcard extension so that BatchFileSave will

* generate a unique file extension consisting of three digits.

*

* Note: Before running this script, create two batch files

*       (ISExamp1.bat and ISExamp2.bat) in the root of drive C.

*       For best effect, you should delete or move any other

*       files named ISExamp1.* or ISExamp2.*.
