So far I have not been able to reproduce this behavior. Does this happen with other samples as well?

I'm not sure I understand you correctly. Does the listview hide the context menu? Everything seems to work on my Windows 2000 SP4. Could you please somehow make a screenshot of what you mean and post it here?
Or do you mean the context menu that is displayed when you click on the listview's background (it contains "New" and maybe some other items). Well, this menu is indeed incomplete. Unfortunately you can't retrieve this menu entirely from the shell. Items like "Copy" and "Paste" must be added "by hand". If I find some time, I'll update the sample to do this. Maybe I'll also use the opportunity and replace vbAccelerator's listview with my own (the vbAccelerator listview has many bugs).
Kind regards

This looks like a problem with AutoUpdate. To locate the problem I need more info:
- Do you copy within the ExplorerTreeView sample or do you use Microsoft Windows Explorer (while the sample is running)?
- Which folder do you copy from?
- Which folder do you copy to?
- Which file do you copy?
- Does it happen when you copy 1 file or only if you copy multiple files at once?
Also could you please download the attached program, start it before copying, make ExplorerTreeView crash and post the program's output here?
- Launch the project into Visual basic
- Run it
- Go to d:\
- Right click on "telephone portable.xls"
- Copy
- go to "d:\!Ecole"
- Right click on the treeview's item "d:\!ecole\"
- Paste
- The file is copying and the error message.
The log is :
Just start changing things in any Explorer window...
(i.e. rename/move/create/delete any file or folder,
change a file's association, insert/remove a CD,
add/remove a network share, etc...)

I'm still not able to reproduce the crash, but that's more or less normal, that the Windows shell notification system works slightly different on each PC.
So I'm afraid all I can do is watch my code, more or less guess where the crash happens and try to fix it. Don't expect a bugfix too soon, sorry.

I finally found time to work on this issue. Because I can't reproduce the crash on none of my systems, I'll need some assistance from you.
At first we've to find out which of the shell events causes the crash. In the attached build, SHCNE_CREATE and SHCNE_DELETE are not handled. So if it still crashes, it's very likely that SHCNE_UPDATEDIR is the reason.
Please test the attached build and tell me if it is still crashing.
Okay, so this one hopefully doesn't crash. I've activated SHCNE_CREATE and SHCNE_DELETE again and deactivated SHCNE_UPDATEDIR. SHCNE_FREESPACE isn't handled anyway.
You're absolutely right.
The attached build will popup a MsgBox before it handles one of the involved events and one afterwards. Inbetween those two message boxes you should get other message boxes telling which code succeeded so far and what some important variables are set to.
If the program crashes between a "received SHCNE_*" and the corresponding "handled SHCNE_*" message, I need all messages of this "received"/"handled"-block.
If it crashes outside such a block, we've a problem I guess.
That's strange. Just to make sure it really is AutoUpdate that is causing the crash, I've disabled it completely. So if this build still crashes, it's not AutoUpdate.
Damn, then it could be everything and nothing. Could you please test some older builds while I search for another possible source of the problem? Maybe some recent change is responsible.
