How can I programatically determine the version of Outlook that's running? I saw here in some examples using Self.HostMajorVersion in the TAddinModule object, but that's not a valid property - compile errors. I have HostVersion, but that is showing 9.0.0.0 in both Outlook 2010 and Outlook 2003.

I am using Add-In Express 2009 with Delphi 6 Pro.


Thanks

Hi Chris,

The HostMajorVersion property was introduced in Add-in Express 2010 (version 6.1). Please try to use the OutlookApp.Version property instead.

Dmitry,

Thanks - that was just what I was looking for.

What does the TAddInModule.HostVersion property then refer to that would indicate 9.0.0.0 in both Outlook 2010 and 2003?

Hi Chris,

The TadxCOMAddInModule.HostVersion property returns the value of the host application Version property and returns '9.0.0.0' string in case of an exception:


function TadxCOMAddInModule.GetHostVersion: WideString;
begin
  Result := '';
  try
    case FHostType of
      // ... 
      ohaOutlook: Result := FOutlook.Version;
      // ... 
    end;
  except
    Result := '9.0.0.0';
  end;
end;


In which event handler do you access this property?

Dmitry,

In the OnCre ate event:

procedure TAddInModule.adxCOMAddInModuleCreate(Sender: TObject);
begin
ShowMessage('Outlook version ' + Self.HostVersion);
end;

Hi Chris,

The OnCreate event is raised right after your module is created, all public properties are initialized later. Please use the OnAddInInitialize event instead.
