Not running tool

[NestorasPapadopoulos]

Hallo,
I have made an Add-In tool using Visual Studio 2010 for ArcMap 10.0
I added it with the Add-In Manager in a custom toolbar, but when I pressed
the button nothing happend. It should select and move a polygon shapefile (poly_C1toend)
according to the coordinates of a selected row of a point shapefile (trig_srtm30). Then it should
run a tool (topo_iter) mabe in model builder from a custom toolbox (Toolbox_g).
Can anyone help me with that?
Here is the code

A Tool requires you to interact with the map display, was this your intention? A button is a control you click on and something happens (e.g. zoom to full extent).

Your code does not seem to have the Sub that handles the event. So for a Tool you would expect to see an OnMouseDown event if your button was a Tool button or an OnClick Sub if it is a standard button.

Thanks for replying me! Excuse me if I seem boring but I am new to Arcobjects and I need to get used to it.
I n my code I replaced

Public Sub New()

with

Public Sub OnMouseDown()

but still nothing happens. I was wondering if it is just the correct place
of OnMouseDown or is there any other mistake in the whole code??

You still need a NEW sub, that's required to instantiate the object, in your case a Tool. I would look at this page to help you understand how to build an addin.
