Use CRichEditCtrl::StreamOut() and write your own stream callback function, in that you copy raw bits from rich edit control to HGLOBAL. See the EDITSTREAM and CRichEditCtrl documentation for details. Robert-Antonio

the callback function is called, passing the data in segments, so should i allocate memory on the heap for each call and the integrate the whole data in a newly allocated memory or is there a way to keep appending data to the buffer allocated only once....(or is there a way to find in advance how much buffer we should have?) thanks ahmed

The callback function takes the cb parameter, which contains required size of CRichEditCtrl data. You can grow the HGLOBAL memory with GlobalRealloc. Robert-Antonio
