[RESOLVED] Question about drag in Windows 8

[georgekar]

I realize that in Windows 8 when I use admin rights in my aplication I can't drag from wordpad to my usercontrol, but I can drag text from a form in my application to another form. When I use no admin rights then all works fine.
I can drag text from my application to wordpad in either rights (admon or not).
In windows 7 I have no problem.

Depends on user rights of the applications. On Vista for example, I cannot drag any files from Explorer to my VB app if I run VB with elevated privileges. Generally speaking, you can't drag from a lower privilege to a higher privilege.

Sounds like this is what you are experiencing. If you were to run VB at normal user-rights (not admin, not elevated) then ran WordPad 'as administrator', you wouldn't be able to drag from your VB app to WordPad.

Thank You LaVolpe I understand now, we have to use a drag operation is same level application

[LaVolpe]

Not completely. Either same or from higher to lower, not lower to higher.

Oh, and a crappy workaround for my Explorer to VB with elevated privileges? I open WordPad with elevated privileges, choose File|Open menu, then drag from that to my VB app.

It's not limited to VB either; this behavior applies to any drag and drop like that on Windows 8 (and apparently, Vista). But not on 7. Long live 7! Only good Windows since XP.
And unfortunately even the advanced API drag/drop can't get around it.

Yep, didn't mean to imply VB-only issue. With WordPad, one opened normally and another 'as administrator', dragging text from low to high is prevented.

[fafalone]

Yeah I just wanted to make a note of it anyway, since so many drag and drop limitations are VB-only and can be worked around via API/COM.
