So what I >going to do ? Increase heap ( HOW ? )... Nope. You're stuck. The listbox (which is part of a combobox) only allows you to insert 32k of data (I forgot exactly the reason why it isn't 64k, but I believe it has something to do with internal state data per item that is maintained). The only thing you can do is write your own listbox, but that probably isn't feasible. >2. How to control WM_SIZE ? I assume that you want to limit either the maximum or minimum size of your frame? If so, you need to subclass the frame and process the WM_QUERYTRACKINFO message and set the ptlMinTrackSize/ptlMaxTrackSize fields of the TRACKINFO structure to the desired values. >Thanks in advance.
