In order to show progress, you have to know two things: total work to be done and current amount of work completed. MsiProcessMessage is used to notify Windows Installer how much work has been completed. Who knows how much work has been done? If it is the EXE that you cannot modify, then I don't know how you could use a realistic progress bar.
You could fake the progress bar by creating a custom action that spawns two background threads. One thread is the EXE that needs to run and the other is a timer. When the timer updates you could increment the progress bar through MsiProcessMessage. To do this trickery, you'd have to estimate how long the EXE should take to run. If a computer is faster, then your task will finish before the progress bar is filled up. If the computer is slower, then your progress bar will get "stuck" at 100% completed. I have a lengthy executable that runs at the end of an installer. My ProgessText for the custom action includes the text "This may take several minutes. Please be patient." The users don't get a progress bar, but their expectations are set. - Don Benson - On Wed, Mar 18, 2009 at 1:57 AM, Michael <mich...@gnhsoft.com> wrote: > Hi Richard, > > Thanks for your suggestion.
