Simple drag/drop in VB.Net 2k5 under Vista?

[Steve Bottoms]

Hi, all! Using VB .Net 2k5 under Vista Business...

I'm trying to put together a very basic drag-and-drop for file
copying, and can't seem to get DragDrop events (Form, PictureBox,
TextBox, etc) to fire at all, and DragEnter only fires if the drag
operation STARTS on the form (kinda defeating the purpose of a
drag-and-drop file copier). Is there some trick to getting it to
work? I've tried several different samples from MSDN and this forum,
and still no-go. Regardless of whether I'm dropping on a form or
control (yes, I'm certain the AllowDrop properties are set to TRUE),
any attempts to drop from outside the main Form only displays the
slashed-circle cursor (can't drop). Event handlers for DragEnter and
DragDrop have been created and implemented per examples, but still
nothing.

Suggestions? Ideally I want to use something like a PictureBox, but
after having read that MS says PictureBox wasn't intended to be used
like this, I'm sticking to just implementing the code at the Form
level (I can pretty it up later).

Thanks!
Jack

Are you running the IDE 'as administrator'?

The reason I ask is you cannot drag and drop between things
with different levels of access.

Try running the compiled version.
