BatchMoveEx 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 BatchMoveEx function.

*

* This example script moves lines within a batch file.  First,

* it calls BatchFileLoad to load the file.  Next, it moves

* the first PATH command to the end of the file.  Then it

* moves the first statement that references Share.exe ahead

* of the statement that launches Windows.

*

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

*       named ISExampl.bat in the root of drive C.  For

*       best effect, the first line in that file should

*       be a PATH command; the next statement should

*       launch Windows;  the last statement should execute

*       Share.exe.
