Subclassing 3rd Party RichTextBox

I need to watch for any new text being sent to a 3rd party richtextbox. Because of inefficiencies (and other issues) in simply watching the richtextbox itself and performing updates when it changes, I'd rather just watch for the WM_SENDMESSAGE (or whatever it's using to update the window), make a copy of the text it's sending to the richtext for my own programmatic uses, then return the control back to the window.

Any suggestions on how I can find how the window is being updated (with WM_SendMessage, etc) and/or get the text it's using to update it?

thanks in advance,
J
 
Okay, Maybe I don't quite understand but why don't you just look at the change? Are you doing some massive code? I may need more info.... Brad,

The change occurs, on occassion, too quickly to ensure nothing is missed because of a relatively small buffer. Hence my attempts to approach it by subclassing.

I'm not sure what events the 3rd party control has. I don't have access to it. I was hoping I could do some trial and error subclassing to figure out what events were happening and go from there.

This is my first attempt delving into subclassing - so if it sounds like I don't have a clue what I'm talking about, it's because I don't have a clue what I'm talking about.

Consider a busy IRC channel with 3 lines of buffer and trying to make sure you get every text line - that's pretty analogous to the situation at hand.

thanks again,
J
 
If it is a decent ActiveX control you should be able to add it to your project and then use the object browser to see methods, events and properties for the control.
