Creating a CDC from a HDC

· One min read

If we get handle to a DC and sometimes we might want to create a CDC from that. One example is owner-drawn lists, combos, and buttons. we will receive a draw item message with a hDC. The below code can be used to convert hdc into CDC.

 void MyList::DrawItem(LPDRAWITEMSTRUCT lpDrawItem) { 
  CDC* pDC;
  pDC = CDC:FromHandle(lpDrawItem->hDC); 
}

NOTE: This technique for any of the other MFC class/ Windows handle pairs too.
