ReplaceProfString Example
InstallShield 2020 ยป 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 ReplaceProfString function.
*
* ReplaceProfString is called for the first time to replace
* the szKeyName key value szOrigValue with the value
* szReplaceValue. Then ReplaceProfString is called again to
* replace the newly set value of szKeyName, szReplaceValue,
* with szOrigValue.
*
* NOTE: In order for this script to run properly, you must set
* the constant EXAMPLE_INI to reference an existing
* initialization file on the target system. That file
* should include the following lines:
*
* [Old Section]
* Old Key=Old value
*
