    Controlling an edit control

    First off, I'm using the win32 api. Now here is the problem, I want to have a multiline edit box control another multiline edit box when a its vertical scroll bar is moved. I know that edit boxes don't send a message to the parents WM_VSCROLL. I only get the edit controls EN_VSCROLL message from the WM_COMMAND message when a scroll bar's arrows are pressed or when a you move the scrollbar by not using its thumb. Any suggestions?

    You could try trapping the EN_VSCROLL for the first edit box and sending an EM_LINESCROLL or EM_SCROLL message to the second edit box.

    ...and when you're processing the EN_VSCROLL, make sure that it came from the first edit box only, otherwise sending the EM_SCROLL to the second edit box will trigger it also (which will probably end up posting repeated EN_VSCROLL messages until your second edit box can scroll no more).
