I have an executable that we've written. I call this executable from in Installshield.
Does anyone know how I can show different progressbar messages during the execution of this executable?
I know that LaunchAppAndWait has callback functionality but how does this actually work?
Do I need to update the textbox on the progressbar window from in the executable itself or do I need to return a string from the execuble that contains the current statusmessage?
Is it actually possible to use the callback functionality of LaunchAppAndWait from in a Basic MSI project where you call script via InstallScript custom actions?
Because I've read that the event 'OnLaunchAppAndWaitCallback' will be triggered but is this not only working in InstallScript projects??
Did you find any solution to your post? I want to update the progress bar using LAAW_OPTION_USE_CALLBACK option in LaunchAPPAndWait. But not sure how to use it.
