How do I know if the cancel button was clicked?

junrau · 9th October 2007, 22:27

In my page leave function, the following call returns 0 for both the cancel button and the next button, so my validation occurs when the cancel button was clicked:

ReadINIStr $0 "pageComponentParameters.ini" "Settings" "State"

Is there a way to know if the button clicked was Cancel vs. Next?

The leave function isn't called when the Cancel button is clicked. If you're talking about the code after InstallOptions::show is called, then the answer is waiting for you on the stack. If the user clicked Cancel, InstallOptions::show will return "cancel" on the stack. It'll return "success" for Next and "back" for Back.

The Leave function is definitely being called when I click Cancel. I am using the ExperienceUI, so I have no InstallOptions::show call. Would that make a difference?

That is a known bug with ExperienceUI.
