Laura,

Thanks for the article. I am having difficulty with the addin wizard. First, I don't have the option of choosing Visual Basic .NET, just Visual Basic. Second, MapPoint is not listed as one of the available hosts. Yet MapPoint 2004 and Visual Studio 2003 are installed on my computer. Any suggestions?

The MS instructions start:


With Microsoft Visual Basic version 6.0, you can use the same Add-In Designer to build a COM add-in that you would use to build a Visual Basic 6.0 add-in. This designer wraps the IDTExtensibility2 interface so that you do not have to implement it yourself. It also registers your add-in for you.

Note To create a single add-in that works with multiple Office applications, you must use the Visual Basic Implements statement when creating add-ins, because the Visual Basic Add-In Designer does not support multiple host applications in one .dll file.

Start Visual Basic 6.0, and on the New tab, click Addin, and then click Open.
A designer class (Connect) and a form (frmAddIn) are added to your project.

Note If the New Project dialog box doesn't appear when you first start Visual Basic, on the File menu, click New Project.

In the Project window, expand the Designers folder under MyAddIn, and then double-click Connect.
In the Application box, click Microsoft MapPoint, and then in the Application Version box, click either Microsoft MapPoint 9.0 (version 2002) or Microsoft MapPoint 11.0 (version 2004).


Is the problem, that MapPoint does not appear in the Application Version Box?

The only thing I can think of that I did before the above, was to add the MapPoint control to the VS designer - but that was for an earlier app that used the MapPoint control. Ie. I don't think you have to do it for add-ins.

MapPoint will not show up in the Add-In wizard is if it was installed before Visual Studio .NET.
Re-installing MapPoint after VS7 has been installed will set the correct registry keys in order for Visual Studio to see MP as an availible add-in host.

Hope that helps.
