There is a problem with the CExtComboBox when in custom draw style, that the drop-down arrow flickers.


I reported this problem a couple of months ago, sent you sample application and clips about this problem.


We have to release a product, and this is one of the main unresolved issues in it. Can you please fix this problem?


Thanks,


Ron.

We have just uploaded the latest code. Sorry for the delay. Please do not publish links to our ftp server.

We have already seen this problem but is was fixed. Maybe the Prof-UIS library you downloaded from FTP doesn’t contain the bug-fix yet. We have just uploaded the latest code, so please download it again and let us know whether the problem persists there.

Yes - this problem is solved in the 5-11 version.

In version 2.83, we already fixed a similar issue, so probably the problem is eliminated. Would you download the latest version from our FTP and try it?

The flicker is gone! great news.


I see also that the combo drop-list has the skinned scroll-bar.


However, there is a small bug:


I have a custom-drawn combo-box.


When the number of items in the list is big, and the scroll-bar appears, the selected item is duplicated - and I see that the you add a new item to the drip list, because the scroll-bar handle gets a little smaller.


If I try to select this new item, when I hover over it, it changes to the item in the list above it... this happens for 3 items, and then the list gets back to normal.


Let me know if it makes sense....
