Re: AxShDocVw and DragOver

Still one further point: In my app, if I drag plain text over the webbrowser
control that is wrapped by my user control, the webbrowser is handling the
dragover as it shows the dragover mouse cursor (and I supose that Webbrowser
accepts only a string object). But as before, without being able to give it
my IDropTarget object, all is for naught.

I noticed from a point made in your first link below, that GetDropTarget is
called by mshtml simply to get the DropTarget object - probably once - and
not on every dragenter. Perhaps the call is made prior to my app being able
to connect up the interface? Perhaps GetDropTarget is called when the
AxShDocHost is initialized? This is certainly before I can hook my
IDocHostUIHandler into it using:
Try
' tell WebBrowser that we are its host

Dim obj As Object = wbrChart.GetOcx()

Dim oc As IOleObject = obj

oc.SetClientSite(Me)

wbrChart.RegisterAsDropTarget = True

Catch ex As Exception

End Try

Any light on this possibility?
