Re: AxShDocVw and DragOver

Hi Roy,

Thanks for your feedback.

Yes, I have done some test in VB6.0, it seems that VB6.0 usercontrol can
intercept WebBrowser's messages without any problem. I am not sure why
VB6.0 does not go with Win32 messags processing model. However, I suspect
that because VB6.0 is based on COM, which is easy for interprocess
communication, so maybe WebBrowser internally delegate the drag&drop
messages to the underlying parent usercontrol. However, for .Net
usercontrol, it is not a COM control, so there is no build-in support for
this.

Currently, for this issue, I think we have 2 options:
1. just use the VB6.0 usercontrol to wrap the webbrowser control, then
place all the drag&drop function code in VB6.0 usercontrol side. At last,
in .Net winform, we can add the entire VB6.0 usercontrol in the .Net Form,
and use it.
2. go with the COM interop IDOCHostUIHandler interface to react to the
webbrowser drag&drop events.

I think #1 is much simpler than #2 option. Thanks
