Hi,
i try building a Outlook Addin with VStudio .net 2003. Its a simple
Button, i want that button to call another Application later with
ShellExecute. Now my Goal is to show it and Pop up a MessageBox.
Compiles fine but the MessageBox dont Pop up ! The Box itself Works, i
get no error on Hresult, i tested the Message in OnConnection ! Any
Ideas ? Someone Told me the third Param of the SINK_ENTRY_INFO has to
be 0x01 and is addicted to what event occured !?
here's my Code (i made it ahalf with the Assistant):

originally created on.
// 2) You chose 'Yes' when presented with a message asking if you
wish to remove the Add-in.
// 3) Registry corruption.
// you will need to re-register the Add-in by building the
MyAddin21Setup project

Dmitry Save'd the day ! Thank you !

The Problem as follows:
First I made my Button like this:

//---------------------------
// Connect.cpp
//---------------------------

CComQIPtr Office::_CommandBarButton spCmdButton(spNewBar);

m_spButton = spCmdButton;

pHdl-DispEventAdvise((IDispatch*)m_spButton,&__uuidof( Office::_CommandBarButtonEvents));

//---------------------------
// Connect.h
//---------------------------

CComPtrOffice::_CommandBarButton m_spButton;

Now I make it like this:

//---------------------------
// Connect.cpp
//---------------------------

spCmdButton = spNewBar;

pHdl-DispEventAdvise((IDispatch*)spCmdButton,&__uuidof (Office::_CommandBarButtonEvents));

//---------------------------
// Connect.h
//---------------------------

CComPtrOffice::_CommandBarButton spCmdButton;
