CString TotalStr = "123456";

char* Buffer;  
HGLOBAL ClipBuffer;
EmptyClipboard();
ClipBuffer = GlobalAlloc(GMEM_MOVEABLE, TotalStr.GetLength() + 1);
Buffer = (char*)GlobalLock(ClipBuffer);
memcpy(Buffer, TotalStr.GetBuffer(),  TotalStr.GetLength());

EmptyClipboard The EmptyClipboard function empties the clipboard and frees handles to data in the clipboard. The function then assigns ownership of the clipboard to the window that currently has the clipboard open. BOOL EmptyClipboard(VOID) Parameters This function has no parameters. Return Values If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError. Remarks Before calling EmptyClipboard, an application must open the clipboard by using the OpenClipboard function. If the application specifies a NULL window handle when opening the clipboard, EmptyClipboard succeeds but sets the clipboard owner to NULL. QuickInfo Windows NT: Requires version 3.1 or later. Windows: Requires Windows 95 or later. Windows CE: Requires version 1.0 or later. Header: Declared in winuser.h. Import Library: Use user32.lib.
