Whenever I hit something that looks like a system issue, I use the following rules; #1: Suspect my code #2: See rule #1 It's stood me in good stead for over 20 years now, and only once has it failed, when I discovered a locking bug in C-ISAM for DOS. :) That was real fun to find.

You need to open the file in binary mode: outFile.open("C:\\Junk.txt",ios_base::out | ios_base::binary); Hope that helps. Karl - WK5M PP-ASEL-IA (N43CS) PGP Key: 0xDB02E193 PGP Key Fingerprint: 8F06 5A2E 2735 892B 821C 871A 0411 94EA DB02 E193

Wow, you must have a massive screen to be able to display that many windows and still be able to read them. I think you should rethink how you are displaying your data to your user. there is absolutely no need to keep that many windows around. One solution would be to create only as many 'CmyView's as you can display in the parent view at one time, then simply swap the data in and out depending on the position of the scroll bar. Even with the 16 bit limit of the WM_VSCROLL message that would give you a limit of 32767 views, if you used Get/SetScrollInfo() instead of WM_VSCROLL you could have a limit of 2^31 views without the problems you are encountering with more than a mere 1800 views.

The answer seems to be that with my current versions (I down load updates regularly so I don't think the problem has been address just yet) that a CWnd object CANNOT handle MoveWindow and a value larger than 32768 (in a rect or specified as just integers). The code compiles but the window is not moved or resized as specified in the MSDN documentation. For me the solution was to create a new view of type CWnd (call it CHolderView) and place it in the CScrollView and then place the CmyView objects into the CHolderView. The key is to make the CHolderView initially large enough to hold all my CmyView objects. If you try to resize the CHolderView you can't make it bigger than 32768 after it is created. I'm also going to post this solution as its own message so others might be able to see it without having to follow this thread. Thanks again Gary for your attempts at solving this dilemma. Chris
