[wix-users] Message Box in Wix Control & Custom Action

[Hoover, Jacob]

I would strongly advise against a CA using a UI...  How are you going to handle the myriad of different modes (Quiet, Silent, etc)?  The proper way is to use session.Message to request a prompt from Windows Installer, however: https://msdn.microsoft.com/en-us/library/windows/desktop/aa368322%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396

To provide a little more info, I am using a C# Custom Action. Also, I tried MessageBox.Show("String value") inside the Custom Action, but it *doesn't *compile the Custom Action project in VS. Not sure, what namespace or Assembly reference is missing.

Also, I am not sure how to display a Message Box from within a UI Dialog without Custom Action. Please help.

Regards,
Venkatesh
