IE Toolbar Custom Images & Bitmaps

[Zach]

I see many Internet Explorer toolbars (such as the AIM toolbar, or the
Viewpoint Toolbar) that do lots of custom button and bitmap things.
>From the standard Re Bar control documentation, I can't figure out how
they're doing it.

I want to start by doing something simple and just have an M x N bitmap
place at the very left hand side of the toolbar. I didn't see an
obvious way to just put an image there, it seemed like everything had
to be buttons. So I thought about making a button that used an image
instead of text. But then there's a few problems with that as well.
For one, the image is only the small icon, I don't see how to make the
entire area of the button be an image. Secondly, a highlight box will
get drawn around it when I drag the mouse over it. And thirdly, that
has to use an image from the standard "toolbar button image list" that
I create, which puts restrictions that I have to make the image 16x16.

A good example of what I want to do is on the AIM toolbar. On the left
hand side of the toolbar they have a blue "AIM" image with their logo,
and when you click it it makes a drop down. I basically want to do
exactly the same, except make nothing happen when you click it.

Any ideas how I can achieve something like this as well? I don't want
to interrupt the normal functionality of IEs toolbar placement, so that
if I send messages like TB_ADDBUTTON etc, It still puts them to the
right of my image.

Thanks
