문제
when you erase a coloured text. By default, the control sets the new entered text colour back to that was recently erased. how can you avoid that? do you need to check each character style before you type?
UPDATE:
I'm trying to set the text color like this.
SendMessage(hEdit, EM_SETSEL, start_pos, end_pos); //select text for coloring
CHARFORMAT cf;
memset( &cf, 0, sizeof cf );
cf.cbSize = sizeof cf;
cf.dwMask = CFM_COLOR;
cf.crTextColor = RGB(255,0,0);
SendMessage( hEdit , EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf);
SendMessage(hEdit, EM_SETSEL, -1, 0 ); //deselect text
cf.crTextColor = RGB(0,0,0); //reset colour
SendMessage( hEdit , EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf); //set colour
해결책
Your question is quite unclear. Wild stab at it: you lose all formatting when you assign the Text property. Be sure to use AppendText() instead. And to set the SelectionColor and SelectionBackColor properties back to what it was after colorizing any text so that newly entered text gets the preferred default colors.
