Hi,
When creating a new addon project there is a reference to Interop.SHDocVw dll but this DLL not including IShellUIHelper2 and IShellUIHelper3 interfaces. can i replace it with a referance to Microsoft Internet Controls (COM Object)?
My addon can still run on IE 6 for example?

Thanks,
Omri

Hi Omri.

By default, the Add-in Express wizard suggests you to add the Version-Neutral reference (IE6 and above supported). That is why you can't find IShellUIHelper2 and IShellUIHelper3.
Of course, you can replace Interop.SHDocVw with the new version.

If you use any method/properties that are not available in IE6, you will get runtime errors.

You need to implement all of these interfaces. IE will call the corresponding interface automatically.
By the way, you can define any interfaces manually in the code. Please use the Reflector tool to extract the interface definitions.
