Adding image to Outlook commandbar button

[saturn]

I am writing a VC++ application where I have to add a commandbar and a
button to commandbar on any new inspector window. I have successfully
added the commandbar and button to my commandbar. I have done these in
a handler of New Inspector.

Now I am stuck with following issues:
1. I have to add an image to my button added to the commandbar. How
can I do this in VC++?
2. How do I register a handler for my button click?
3. Is there any property of commandbar through which I can uniquely
identify it? This will help in making decision of adding commandbar if
already not present.

Any pointers on these will be very helpful.

Regards,
Pradeep

Please do not multipost. I answered your question in
developer.outlook.addins.

Now I am able to trap the click of my button. But the callback
function receives CommandBarButton. Using this how I can identify the
inspector on which the button was clicked? How suitable is to conside
the active window?

ActiveInspector usually works, but not always.

The best practice is to construct a unique Tag property for each button you
create. I usually use a GUID or unique string value with a Key value
assigned to each open Inspector. The key value gets incremented each time an
Inspector is opened. That key is stored in a public property in the
Inspector wrapper class so it's accessible. I make up the tag value with the
GUID and key, then when a Click occurs it will only occur in that wrapper
class in the Click event handler inside that class.

If you don't use a unique Tag then Click will fire in every single open
Inspector, so if you're handling Click in one place and there are 3 open
Inspectors then you'll get 3 click events firing. Using Inspector wrappers
is another best practice, as is using Explorer wrappers to handle open
Explorers.
