First capture all the mouse events using,
SetCapture() API.
While MouseMouse use the,
WindowFromPoint(..) API to find the window under the mouse cursor.

If the window is valid, then send WM_NCHITTEST message to the window, to find out the area in that window.
Hope i understood your question..

You will find all these things in MSDN.

I recommend reading "Programming Windows, Fifth Edition" by Charles Petzold.
Invalidate is used to inform Windows that the window needs redrawing. When the thread's input queue is otherwise idle, Windows will generate a WM_PAINT message for any window that has an invalid region. This has two effects: it centralises all painting in the WM_PAINT handler, and it defers painting until all the user's input has been processed. To inform Windows that an area of the window needs repainting, use InvalidateRect or InvalidateRgn. Multiple calls to InvalidateRect or InvalidateRgn build up an invalid region.
In your WM_PAINT handler, you can find out from the device context which areas of the window are invalid and hence need repainting. The PAINTSTRUCT returned by BeginPaint (from MFC, the CPaintDC's m_ps member) has a member rcPaint which is the bounding box of the invalid region. If you want to get the invalid region itself, you can call GetUpdateRgn but you need to call it before BeginPaint (i.e. before constructing your CPaintDC for an MFC window).

I don't get the attitude of these people. They want help and if you speak the reality to them, they will downvote you. Idiots. I will give my 5 to bring it up, but my vote is silver and so has less weightage... Anyway this votes doesn't matter. I hate the people who ask for help and then vote 1 when you tell them the truth

Hi,
I'm getting the following exception as follows, while executing in release version:-
unhandled exception at 0x7c910f29 in ere.exe: 0xC0000005: Access violation reading location 0x00000200.
And also if i debug, it is telling there is some problem in Cabc::~Cabc(void). But this kind of distructor i never written.
Any clues please?
Thanks

Meomory allocated by your code is corrupted, or you have used it wrong way(out of index etc.).
But withoug seeing code its difficult to guess.

That sounds like you've dereferenced a NULL pointer somewhere, (and either using something inside a large struct, or you've incremented that pointer a few times before it's crashed)

Where does call stack takes you in the code ?
You have not your code, BTW.
|
|
|
|

Carefully checking the code of the class should reveal the problem. If you are still stuck, it sounds like it could be crashing in the destructor of one of the class members. To debug these, add an empty Cabc::~Cabc() {} function and set a breakpoint in it. Then you can single step through the destructors of the members.

Hi altogether,
Creating a new MDI Child, create the controls on the View, initialize a Grid with data.
It flickers on the screen during the hole creation.
At the moment i use a LockWindowUpdate on the MainFrame and an UnLockWindowUpdate at the end of
initialisation.
But it provokes some display-irregularities, for example the textboxes which are getting the focus
won't be redrawn ( even a textbox.RedrawWindow() or textbox.Invalidate() doesn't refresh it )
A SetRedraw(False) works only for the view, not for new views in creation mode.
Does someone have an idea how professional applications resolves this problem of flickering?
Big thanks

CButton::SetIcon takes one paramter, isn't it?

SetIcon has a Hicon that you cal use of LoadIcon

Well first of all thanks for telling me to buy "Charles Petzold" (Hats off to the author)but im little bit confused that the book was written in 1998 and will it hold true for todays OSs like XP & vista(I hav 5th edition) or is there any latest edition of that.
Further, I wnna know wat to use VC++6.0 or VS2005.
Although the answer would be VS2005 but wont i be illiterate about VC6 or will it cover that too.
Spread wat u Know!
