Certainly the routine I put in get's called when I'd expect it to, I just don't know how to make sense of the parameters. Re: Tooltips and Trees Tomasz Sowinski28-Aug-01 5:25 Tomasz Sowinski 28-Aug-01 5:25  You should have pointer to NMTVGETINFOTIP structure, which is full of relevant information. Tomasz Sowinski -- http://www.shooltz.com Re: Tooltips and Trees Malcolm McMahon28-Aug-01 5:28 Malcolm McMahon 28-Aug-01 5:28  Yup, I think that's the structure (this would be a lot easier if I had the code here). The structure I get contains a window handle and a what is probably a controll id. But what I need to access the data and supply the text is the HTREEITEM handle, which just doesn't seem to be arround. Nor can I find anything in CTreeCtrl that seems intended to look it up. Re: Tooltips and Trees Tomasz Sowinski28-Aug-01 5:34 Tomasz Sowinski 28-Aug-01 5:34  Yup, I think that's the structure (this would be a lot easier if I had the code here). The structure I get contains a window handle and a what is probably a controll id. You're probably talking about NMHDR - it contains a handle and an id. You can cast the pointer to *NMTVGETINFOTIP to get more info - assuming that you're really handling TVN_GETINFOTIP.

I may well be looking at too generic a message too. I'll give it a go tonight. Memory leak Noman Nadeem28-Aug-01 2:16 Noman Nadeem 28-Aug-01 2:16  Hi, I have come accross a memory leak in my project ... could anyone suggest any memmory leak testing utility which will help me pinpoint the source of the leak regards Re: Memory leak Anders Molin28-Aug-01 2:23 Anders Molin 28-Aug-01 2:23  BoundsChecker from Numega is great.

Re: Memory leak billb211228-Aug-01 6:15 billb2112 28-Aug-01 6:15  BoundsChecker does work wonders, but the object dump should do a pretty good job of telling you where your leak might be. Sometimes, if you're lucky, if you click on the object name or the memory address the debugger spits out right below "Detected memory leaks -->" it will put you in the right area of the source. If it doesn't, then you'll have to do a little fishing on your own or consider NuMega products. Bill http://www.ratebeer.com Re: Memory leak Derek Waters28-Aug-01 14:08 Derek Waters 28-Aug-01 14:08  Actually, if you really want to track down these memory leaks without forking out for BoundsChecker, there is a really good debugging trick described in Knowledge Base Article Q151585 which described the _crtBreakAlloc variable (You can search for Q151585 or "Use _crtBreakAlloc to Debug a Memory Allocation" in MSDN) Basically, when you get an object dump with numbers next to it, you start your program in the debugger, set _crtBreakAlloc to that number, then run your program. The debugger will break when the memory is allocated that you have forgotten to free. Very very handy. ------------------------ Derek Waters derek@lj-oz.com Two simple questions ...

Print question 28-Aug-01 0:24 28-Aug-01 0:24  I have a plot which uses some line routines of the device context. Lines may be drawn (in some scale) from one point outside the visible area to another. When I draw in my window it automatically clips all lines outside certain client area. When I use the same drawing routine in printing, lines are cut only in the borders of the paper. For this clipping SelectClipRgn may be used. However, it works improperly in preview mode. Does anybody know the way to fix clipping?

Paul M Watt23-Feb-02 16:25 Paul M Watt 23-Feb-02 16:25  Are you looking at the keybd_event API function. It says that you can send any event, hoever it will not work on Windows 95, it does not say anything about windows 98. About "EnableCompoundFile" Maer72728-Aug-01 0:00 Maer727 28-Aug-01 0:00  Why use the statement "EnableCompoundFile()" in the function "CMyServerDoc::CMyServerDoc"? Here, "CMyServerDoc" is a class derived from the class "COleServerDoc". My application is a MDI based server application. Does it have anything to do with "COleServerItem"?
