>From the DTF documentation for Session.Message: "The messageType parameter may also include message-box flags from the following enumerations: System.Windows.Forms.MessageBoxButtons, System.Windows.Forms.MessageBoxDefaultButton, System.Windows.Forms.MessageBoxIcon. These flags can be combined with the InstallMessage with a bitwise OR."
What it doesn't say is you will need to cast the result back to an InstallMessage enum. DTF's Session.Message is a very thin wrapper around MsiProcessMessage, so the behavior regarding how user messageboxes are displayed should be the same. I also posted the above to the thread on Acresso forums. Those other InstallMessage enums are only used by external UI handlers -- they are documented at http://msdn.microsoft.com/en-us/library/aa369545.aspx. InstallStart/InstallEnd are MSI 4.5-only (for multi-package transactions). -Jason- -----Original Message----- From: Christopher Painter [mailto:chr...@deploymentengineering.com] Sent: Tuesday, December 16, 2008 6:46 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Problem with error handling of managed custom actions Jason can answer better then me, but I'm guessing that the Session.Message( InstallMessage ... ) doesn't fully expose this capability of MsiProcessMessage. Also of interest to me are 5 enum values that don't seem to map up to the API. I'm not sure what they are: InstallMessage.InstallEnd InstallMessage.InstallStart InstallMessage.Initialize InstallMessage.ShowDialog InstallMessage.Terminate --- On Tue, 12/16/08, Jacob, Christian <cja...@toptechnologies.de> wrote: > From: Jacob, Christian <cja...@toptechnologies.de> > Subject: [WiX-users] Problem with error handling of managed custom actions > To: "wix-users@lists.sourceforge.net" <wix-users@lists.sourceforge.net> > Date: Tuesday, December 16, 2008, 7:58 AM > Hello, > > I am writing a managed custom action.
