I have only a couple of observations: 1. Using MsiSetExternalUIRecord works better because you get a number of records that you can inspect rather than trying to decode message formats. Each record contains process, file name I think etc. If you actually want a message then MsiFormatRecord() will make one.
2. MsiSetExternalUIRecord callbacks for FilesInUse sometimes contain empty records. It's almost as if Windows populates something with all the candidates but then erases the ones it can deal with, leaving holes. If this happens with the non-record callback it might look strange. Also, I believe I tried to deal with FilesInUse in a non-record callback and I *think* the process names weren't actually in the message - they were in a message just before (or after?), so if you monitor all the messages you might see something like that.

Subject: [WiX-users] External UI Handling FilesInUse This isn't technically a WiX question, but I figured there was no harm in asking: I've written a bootstrapper for our various products, one that uses MsiSetExternalUI to hook into the MSIs to retrieve error messages, progress, and the like (I've based off the example handler found here: http://msdn.microsoft.com/en-us/library/aa368786%28VS.85%29.aspx). I would also like to be able to deal with FilesInUse messages, but I'm unsure how to actually retrieve the information on which applications need to be closed (they don't show up in the message string that gets sent). I've discovered that appending [1], [2], etc. the 1607 message (files in use), the message sent to the UI handler then receives the application names, but when uninstalling directly from Add/Remove Programs, the internal UI doesn't seem to do the string substitution and I end up with "The following applications should be closed before continuing the install: [1] [2]..." being displayed to the user. So basically the short version of my question: Does anyone know a way to retrieve the list of applications for a 1607 (files in use) message in an external UI without screwing up what is displayed by the internal UI when run directly from the .msi? I don't suppose anyone has run into this issue before and found an acceptable solution? -Andy ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users *** Confidentiality Notice: This e-mail, including any associated or attached files, is intended solely for the individual or entity to which it is addressed.
