I think that's the message I handle (don't have the code with me here). 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.

You should have pointer to NMTVGETINFOTIP structure, which is full of relevant information.

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.

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.

Thanks, that's probably it. I may well be looking at too generic a message too. I'll give it a go tonight.

BoundsChecker from Numega is great. You can get a 15-days evaluation copy their website...

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.

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.

something like:
wchar_t* AmA2W(const char *s)
{
int clen = strlen(s);
wchar_t *w = (wchar_t*)calloc(clen + 1, sizeof(wchar_t));
MultiByteToWideChar(CP_ACP, 0, s, clen, w, clen);
return w;
}
Just remember to manually free the returned string.

Hi Molin,
About, fifth parameter in MultiByteToWideChar ...
If i put -1 instead w, then what will happen ?

I guess the function will fail. The fifth parameter is a wide-character buffer...

You need to install the platform SDK to use this function, according to the MSDN.

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?

Dear Sirs,
I wish to create a grid within an application that has a variable name on the left hand side and a value on the right that can be edited. Are there any ActiveX controls that I can use for this?

It seems that we can not toggle the Numlock key on Windows 98.
Is it right?
|

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.

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"?
