Extracting a zip and getting progress feedback
I have tried ZipDLL, ExtractDLL and nsExec:ExecWithLog (using 7zip) and in no cases can I get it to provide me with progress feedback during the extraction process. Either to the log window or to a progress bar would be fine. I just need the user to not think that the installer has stopped responding. The best scenario for not confusing the user as I extract 4gb+ of data has been to force it to pop open the console window (dos box) which shows the 7zip extraction information as it happens. The problem of course is that this is ugly!
Does anyone know a way I can extract the contents of a zip file (or some other archive I can easily create) and have the process report the progress to NSIS -as-it-happens- so the user can see how the operation is doing?
