Update ListBox

[Jiko]

Hi!
I have a ListBox, that presents information and some meassurement values, when I press a "startbutton". But the ListBox doesn't update until the function is done. I wont it to display information during the function is running, so the user can see what's happening.

Have you tried using the Invalidate() function within your loop as your listbox is being updated?

If you use classes like CInternetSession your thread will be blocked until connection is come to the end. I don't know what is the problem with your ListBox, but if you really use classes for INet you must create another thread for them. I realy don't have any problems with refreshing my ListBox-es, the only problem is when i use INet classes and unfortunately Invalidate() function will not help you.
