Just type cximage in search box it will take you to the project which does all this and more

Nice answer but I would like to add something to 'when to use' Callback function is used to get events without having to keep on polling them or keep waiting for them in a loop For example lpTimerFunc mentioned above will be called when the time is elapsed,the program need not bother about it in meantime and continue to do other tasks

IPicture interface returns HDC HRESULT get_CurDC( HDC* phdcOut //Receives a pointer to device context ); Use COLORREF GetPixel( HDC hdc, // handle to DC int nXPos, // x-coordinate of pixel int nYPos // y-coordinate of pixel ); COLORREF SetPixel( HDC hdc, // handle to DC int X, // x-coordinate of pixel int Y, // y-coordinate of pixel COLORREF crColor // pixel color );

Write Your own Myprintf version and call writefile from that function and change printf to Myprintf. Copy printf from printf.c maybe available someplace

Have seen nice article by yongseon Heo at http://www.codeproject.com/useritems/w3client.asp

I think you should go through http://www.codeproject.com/cpp/msnchattext.asp[^] It is an excellent article by Deepesh Dhapola

It should be IID_IPicture and not &IID_IPicture

Oh! It is windowless. So this may help http://www.kbalertz.com/Feedback\_153582.aspx I hope sincerely

It would be wise to compare the result from above formula with result from -s*ay - h*by + cy*(s+h) and if results dont compare have some kind of error recovery. if calculations are not too many and time bound most wise programmers(not me) calculate with 2 formulae and compare results.

I am not expert in this area but this URL might help http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay/mmp\_sdk/playerobject.asp

I assume that you call GetsafeHWnd()in OnCreate(LPCREATESTRUCT lpCreateStruct) function or after it is called and not in Constructor as many times I do :-(

Most Significant Bit is dropped naturally

if you want HWND to control then use HWND hWnd = GetSafeHwnd(); if you want handle to container use HWND m_hwndContainer = GetParent()->GetSafeHwnd();

Check that in project->settings c/c++ tab debug info is set to 'program database' optimization to 'disable(debug)' and in link tab chaeck 'Generate debug info' --PM
