Re: AxShDocVw and DragOver

Thanks for your news. I have gone ahead and started to use the
IDOCHostUIHandler interface per the article you mentioned, as well as
utilizing the code from the custom webbrowser that was already ported to
VB.Net referenced in
http://www.fasioncomputing.com/samples/programming_samples.htm and have the
interface embedded in my usercontrol wrapper. This has allowed me to turn
off the context menu and inhibit the speed keys like the WBCustomizer did (I
really want to avoid as much COM interop in thisw project so I want to avoid
using any of m VB ActiveX components in the DOTNET port).

The only thing remaining is learning how to deal with the IDropTarget
implementation for the object that needs to be returned. I am doing research
on that. Since it appears that IDropTarget is a COM defined interface, I
doubt that I can simply return a reference to my usercontrol, but must
implement the IDropTarget interface and return an object of that type.
