Outlook Explorer Commandbarbutton - click-event 2 times?

Hi,

I've created an outlook com add-in, using Visual studio 2003 (.NET 1.1). In the add-in I created an explorer-commandbar with two buttons. In the click-event I open a winform using: 
Dim _wizardForm As WizardForm
_wizardForm.ShowDialog()

This works fine, but From the wizardform I had to open an Inspector-window, which was not possible because of the ShowDialog. So I changed the code to: 
Dim _wizardForm As WizardForm
_wizardForm.Show()

But now, when I click the commandbarbutton, the click-event is called twice. (tried with breakpoints).

When I add a Thread.Sleep(5000) in the eventhandler, the event is called once, but with a Thread.Sleep(1000) the event is still called twice.

My question: What's the reason for this behaviour, and how can I solve this issue?

thank you,
Bert

Some extra info: I tried using a counter to handle the event only once, but it seems that there are two seperate threads that call the eventhandler, so this trick doesn't work.

Hi Bert.

Do you use a C++ shim for the add-in?

Hi Bert.

Could you check the ShimProgID property of the add-in module? It should be set to the <PropgID> of your shim project. I think that for some reason your add-in was registered twice in the system registry. Please check the following key:
HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\AddIns\<the add-in progid>
I assume you will see the ProgIDs of the addinmodule and shim registered at the same time. It can be a cause of the issue. Try to delete an entry with the addinmodule progId. It should help.

Hi Sergey,

sorry for the late reply, but this was exactly the problem.

Thank you!
