EzBatchAddString Example

InstallShield 2015 » 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 EzBatchAddString function.

*

* This script performs four operations on a batch file:

*

* -- First, it adds a comment line at the top of the file.

*

* -- Next, it adds the line "SET TEMP=C:\EXAPP3", placing it

*    it after the PATH statement.

*

* -- Then, it adds the command "C:\EXAPP3\EXAPP.EXE", placing

*    it after the "SET TEMP=C:\EXAPP3" statement.

*

* -- Finally, it replaces the existing PATH statement with a

*    new PATH statement.

*

* Note: Before running this script, create a batch file

*       named ISExampl.bat and store it in the root of

*       drive C.  For best effect, include a PATH statement

*       in that file.

*
