CRichEditView/CRichEditCtrl mesages

I have a CRichEditView/CRichEditCtrl application and need to 'grab' some of the 'EM_' messages i.e 'EM_SETPARAFORMAT' and EM_SETCHARFORMAT' before they are sent to the Rich Edit Control so I can modify the message data.

I have tried PreTranslateMessage() but these messages never seem to get there.

How do I intercept these messages.

I don't know if this will help, but try the message loop before it sends the messages to the window:
while(GetMessage(0,0,0))
{
if(hWnd==hWndMyWindow)
{
//if msg == EM_BlaBla
//Do what you have to do with the message
}
}

Another way is to subclass the CRichEditCtrl. Construct a CRichEditCtrl derivate using
ClassWizard, and then use SubclassWindow() to dynamically subclass your existing control.
Now the 'PreTranslateMessage()' handler (of your subclassed window) should catch the
messages. If not (some messages MFC just won't let pass through) you need to use a
construct like this:

WNDPROC oldWndProc=wndRichEditCtrl->GetWindowLong(GWL_WNDPROC);
wndRichEditCtrl->SetWindowLong(GWL_WNDPROC, (LONG)MyWndProc);

.

LRESULT CALLBACK MyWndProc(UINT message, WPARAM wP, LPARAM lP)
{
  ...
  switch(message) {
    ...
    default:
       return (*oldWndProc)(message,wP,lP);
  }
  return 0;
}
