Our BA installs several MSI-Packages. One MSI calls a C# CA where we would like to show a MsgBox with an information.
Calling System.Windows.MessageBox.Show has he disadvantage that the box isn't modal and my appear in the background oft he main UI.
I read that session.Message achieves my goal - but I didn't get this work - the information appears ONLY in the log-file an is NOT displayed in a msgBox.
My call looks like this: session.Message(InstallMessage.User | (InstallMessage)MessageButtons.OK, record);
I also read, that ...
Custom actions triggered via a DoAction control event cannot show message boxes.
My CA is scheduled in the InstallExec-Sequence with Execute="Immediate".
Thanks in advance,
