As I've said I don't know C# but if the "IDTExtensibility Interface" exists
correctly I would have thought it should compile to a recognized com-addin.

I am building the project and debugging it such that it starts an external
program and that external program is set to MSExcel. In

With VB6 you can run as a Com-Addin from the VB_IDE, ie step through the
uncompiled code. It's all a bit flaky and means starting everything in the
right order. I have no idea if you can do that with C#, maybe not. Have you
tried compiling it and then adding the compiled dll via the ComAddins
button.

And, to add to the information, am actually adding a new commandbar and in
this commandbad lies my button. Am able to see my commandbar with the
button
only when I start writing " ='...' "

That makes sense if it is only installed as an automation-addin, I explained
that in my last post. If your addin contains effectively only UDFs normally
it should not be necessary to include any buttons at all.

Yes peter, it appears like you said, in
excel--tools--Add-Ins--MyAddin.Connect. Am sorry if I had confused you,
I
was a little unsure.

And for the "tools--ComAddins" one which you said, my Addin was not
already
present there, so I tried to add my ".dll" but it just popped up this
error,

"It is not a valid Office Addin"

though for the latter it needs to have been compiled as such (ie an
Office addin/comaddin).

Am I missing this??? How do I compile it that way?

And the template about "IDTExtensibility Interface" etc which you talked
about are all present.

I am building the project and debugging it such that it starts an external
program and that external program is set to MSExcel. In this excel sheet
opened, I wanted my button to be shown automatically, but I'm having to
first
call one of the Connect events to see it.

And, to add to the information, am actually adding a new commandbar and in
this commandbad lies my button. Am able to see my commandbar with the
button
only when I start writing " ='...' "

I tried lookin in the "Customize" also, but am not able to see my
commandbar
until i start " =... " in any of the excel cells.
