RTF SCROLLBAR

[Gintaras]

It also somehow works, and is easier. But you need to update text in control2 when text (number of lines) in control1 changes. And remove WS_VSCROLL style from control1. And optionally add ES_AUTOHSCROLL style to both controls to prevent word wrapping. And change Edit to RichEdit20A.

To receive EN_CHANGE message from a rich edit control, under case WM_INITDIALOG use

Code:

Copy      Help

,int h=id(3 hDlg)
,SendMessage h EM_SETEVENTMASK 0 ENM_CHANGE

, and insert this under sel wParam

Code:

Copy      Help

,case EN_CHANGE<<16|3
,out 1
