I am using ZipAddDirectiry to make a backup of several nested directories. It takes quite a lot of time to finish.
I wanted to show the user some kind (any kind) of progress .
During the call to zip the window does not get the focus, there are also no callbacks which would allow me to animate a progress bar. I do change the cursor, but this is not enough.
I have tried to open another MDI window with an animated GIF, which would run in paralel with the window which executes the zip action. But unfortunately in all my test cases, the animated gif stopped until the zip process was finished.
ZipAddDirectory is very handy, I would not like to break it down to zipping individual files and directories.
The same problem applies when a SQ server does not respond for a longer time (in case of complex queries)
Any ideas ? |

There is a callback procedure for ZipAddDirectory, but the question is stil valid for
- complex SQL queries (several seconds before returning the recordset) or
- long computation loops |

Hi
you can do that using multithreading
Not sure if the result is worth the added complexity, though
Best regards
