ConfigMove Example

InstallShield 2019 » 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 ConfigMove function.

*

* This example script moves lines in a configuration file.

* First, it calls ConfigFileLoad to load the file.  Next, it

* moves the FILES statement to the end of the file.  Then,

* it moves the BUFFERS statement to the end of the file.

* Next, it moves the statement referencing Himem.sys before

* the DOS statement. Finally, it backs up the original file

* and saves the edited file.

*

* Note: Before running this script, create a configuration

*       file called ISExampl.sys in the root of drive C.

*       That file should include the following lines:

*

*       FILES=50

*       DOS=HIGH,UMB

*       DEVICE=C:\WINDOWS\SETVER.EXE

*       BUFFERS=50

*       Device=C:\Windows\Himem.sys

*
