Hey Spht...

I noticed that SphtBot prevents new text being added to the richtextbox from resetting the start point to the bottom. What API did you use to do that?

None, I reckon. He probably took time out of his day to learn some RTF and modifed RichTextBox.TextRTF instead of using SelStart, SelColor, and SelText. By not chaning SelStart.. he doesn't change the SelStart.

No, I'm pretty sure Spht uses SendMessageA and not the properties that are available on the RichTextBox control. I used to do this my self also, it's much more complex then you probably think it is.

It utilizes the Richedit API.

Which ones in particular?

Hm... I think I found them

SendMessage(rtbChat(0).hwnd, WM_SETREDRAW, 0, intPointer)

SendMessage(rtbChat(0).hwnd, EM_GETEVENTMASK, 0, intPointer)

A lot more is involved besides that

Two more lines to lock events, but those calls are doing what I need :-p

WM_SETREDRAW can be useful in preventing the Richedit from redrawing redundantly when you do multiple things together like append text, remove text, or change scroll positions.

I don't use EM_SETEVENTMASK.
