And I have points where I want to log things, so checking there is a matter of adding a case to the select afterwards that translates the return value into an ERROR_ constant.

I do say it'll take a few minutes at the beginning with a <ProgressText>, but I agree, adding ACTIONDATA calls would give more feedback and allow me to check frequently. So what I understand I need to do is: 1) I call MsiProcessMessage at the beginning of my CA with INSTALLMESSAGE_ACTIONSTART with a handle that contains three things: [1] = "CA_ClearFolder" [2] = "Searching for additional files to delete:" [3] = "Directory: [1]" and then for each directory I enter into, I'd call MsiProcessMessage(INSTALLMESSAGE_ACTIONDATA) with a handle with these contents: [1] = directory I've entered into. Is that the correct way to do it? (specifically, the correct way to tell the ACTIONSTART that the ACTIONDATA should be formatted that way?) --Curtis -- Curtis Jewell swords...@csjewell.fastmail.us %DCL-E-MEM-BAD, bad memory -VMS-F-PDGERS, pudding between the ears [I use PC-Alpine, which deliberately does not display colors and pictures in HTML mail] -- Curtis Jewell swords...@csjewell.fastmail.us %DCL-E-MEM-BAD, bad memory -VMS-F-PDGERS, pudding between the ears [I use PC-Alpine, which deliberately does not display colors and pictures in HTML mail] ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
