Good day!
The following question arose .. how can I set line spacing in richtextbox, I write in c ++, visual studio 2012.

Answer 1

CHARFORMAT fmt;
 fmt.cbSize=sizeof(fmt);
 fmt.dwMask= CFM_OFFSET;
 fmt.yOffset=100;

Here is an offset game that can help you.
then the message was sent to the window:

SendMessage(pRichEd->m_hWnd, EM_SETCHARFORMAT,SCF_ALL,(LPARAM)(&fmt));
