Office Addin upgrade c# code from Office Outlook 2007 to 2010

Question

Hi,
We have a C# addin working in officeOutlook 2007 and we can catch the user events  via eventhandler
outlookExplorer2007.SelectionChange+=

newExplorerEvents_10_SelectionChangeEventHandler(myOlExp_SelectionChange);

We can´t get the similar code to catch the OutLook events in Office 2010.
Application2010.ActiveExplorer().SelectionChange +=

newExplorerEvents_10_SelectionChangeEventHandler(myOlExp_SelectionChange);

Best regards and thanls in advance José

Hi José,

Could you please describe in more detail your problem?
Also: If you run the code from the following link, does the SelectionChange event get triggered?

hi

thanks for you help

the following code works fine in office 2007 but not in office 2010.

the problem is ExplorerEvents_10_SelectionChangeEventHandler is only for office 2007 has far has I figer out

privatevoidThisAddIn_Startup(objectsender, System.EventArgse)

        {
            currentExplorer = this.Application.ActiveExplorer();
            currentExplorer.SelectionChange += new Outlook.ExplorerEvents_10_SelectionChangeEventHandler(CurrentExplorer_Event);
        }

The following code works fine in office 2007 but not in office 2010. The problem is: ExplorerEvents_10_SelectionChangeEventHandler is only for office 2007 as far as I figuered out.

I'm afraid that is not correct. The ExplorerEvents_10 interface is fully supported by Outlook 2010. To convince yourself of the fact, simply fire up VS 2010 an create a new Outlook 2010 Add-in project. Then paste in the code from the above link. I just tested it, and it worked as expected. There are some known issues with items getting locked by Outlook 2010, but this is not the problem mentioned here.

Once again, please test the code, and *please* describe in more detail the meaning of "the following code works fine in Office 2007, but not in Office 2010". Does the code compile? Do you get an error message? Place a breakpoint in the CurrentExplorer_Event handler. Does it get hit?

I've installed Microsoft Office X64 and the project is X64 too.

The interop is V14.0.0

Answer 7

Since you have Outlook 2007 you need to Outlook Interop 12.0, not 14.0

Answer 9

Sorry, I didn't notice that you said 2007 was working.

I would check to make sure you have the latest hot fixes in outlook.  The following webpage indicates there was problems in 2010 with service routines in Outlook 2010

@Joel, Mike:

There is no problem with the ExplorerEvents_10 interface in Outlook 2010. Just try out the sample code which I linked to above, and you'll see that everything works just smoothly.

Answer 11

It is never wise to assume that you have an ActiveExplorer() object, especially at Outlook startup. If anything you should check the Explorers collection for Count > 0 and if so use Explorers[1] instead.

 

The SelectionChange() event is as valid for Outlook 2010 as for 2007. I usually use a different way of instantiated that handler that works equally well in Outlook 2003, 2007, 2010 and later versions. This line assumes an Explorer object, _explorer, declared at class level to keep it alive:

 

    ((Outlook.ExplorerEvents_Event)_explorer).SelectionChange += new Outlook.ExplorerEvents_SelectionChangeEventHandler(Explorer_SelectionChange);

 

The way you're adding the handler, using compound dot operators and ActiveExplorer() will get garbage collected and eventually fail to fire. That will happen in Outlook 2007 as well, so you need to change your code there also.
