Changes to ModalResult Values at XE2 Release
The XE2 release introduced three new ModalResult values: mrContinue, mrHelp, and mrTryAgain.
In addition, four of the existing ModalResult values changed at XE2. If your applications use any of the following four ModalResult values for TButton, you need to make code changes: mrClose, mrAll, mrNoToAll and mrYesToAll. Since these values are stored as numbers in .dfm files, the values change when you migrate a project to XE2. The values have changed as follows:
Before XE2:
mrClose=11
mrAll=8
mrNoToAll=9
mrYesToAll=10
In XE2:
mrClose=8
mrAll=12
mrNoToAll=13
mrYesToAll=14
The following table lists the constants of type TModalResult that are defined for the ModalResult property, along with their values in the XE2 release and XE release (that is, any release before XE2):
