I wanted to get the current mouse cursor image in c++ or c because of the speed of execution. In my application I want to show the cursor in an applet. so I want to get the image as an buffered image. I found that we can get the image as bit map data. but can't figure out how it can do it because of lack of documentation. can you help me to find me a good tutorial to understand how I get the cursor image?

GetCursor function of Win API
The return value is the handle to the current cursor. If there is no cursor, the return value is NULL.

this function returns a handle to the cursor. but handle can do nothing other than passing to a function. what is the function that returns the cursor image as buffered image. should I write my own function to return the cursor? thanks all for your information.

Ouch, that seems to be more complicated than I thought - see http://msdn.microsoft.com/msdnmag/issues/01/10/Cursor/default.aspx ("Win32 Resources: Using C++ to Pro-grammatically Retrieve a Global Cursor's Shape and ID") and http://delphi.cjcsoft.net/viewthread.php?tid=42851 , http://www.autoitscript.com/forum/topic/18981-capturing-the-mouse-cursor/ ,
http://www.luigibianchi.com/code/cursor_shape.htm :

HCURSOR GetCurrentCursorHandle()
{
POINT pt;
HWND hWnd;
DWORD dwThreadID, dwCurrentThreadID;
HCURSOR hCursor = NULL;

// Find out which window owns the cursor
GetCursorPos(&pt);
hWnd = WindowFromPoint(pt);

// Get the thread ID for the cursor owner.
dwThreadID = GetWindowThreadProcessId(hWnd, NULL);

// Get the thread ID for the current thread
dwCurrentThreadID = GetCurrentThreadId();

// If the cursor owner is not us then we must attach to
// the other thread in so that we can use GetCursor() to
// return the correct hCursor
if (dwCurrentThreadID != dwThreadID) {

// Attach to the thread that owns the cursor
if (AttachThreadInput(dwCurrentThreadID, dwThreadID, TRUE)) {

// Get the handle to the cursor
hCursor = GetCursor();

// Detach from the thread that owns the cursor
AttachThreadInput(dwCurrentThreadID, dwThreadID, FALSE);
}
} else
hCursor = GetCursor();

return hCursor;
}
