From: jc on 9 Apr 2010 12:19 Hello, Yes, I did step through the code, and all of return values were OK. The only value that was NULL was the return value from the CreateIconFromResource(...). jc

From: jc on 9 Apr 2010 14:11 Hello, This works OK, but the cursor is not part of the application. The cursor is a separate file. hRetCursor = LoadCursorFromFile(_T("MyAniCursor.ani")); Any ideas, about what is wrong with the initial implementation? -jc

You can put err,hr in the watch window and you don't have to call GetLastError explicitly. I'll wager it is "invalid parameter", one of the most useless messages you can get, because the manuals NEVER tell you what the likely causes of "invalid parameter" are, and since we can't step into the code or even read it, we can't tell which of the possibly several dozen tests for parameter validity are failing! (It is times like these that I realize that Microsoft deserves to lose the open-source battle. They really need to document what the causes of errors are, essentially by explaining what tests are applied) But if something fails, you need to report that, not just assume it had worked. joe **** > >jc Joseph M.
