Hi.

I'm now making my own editor(named it MET below) using open source of Notepad ++.

For protection, I logged on Users's privilege and ran MET with "Run As Administrator" on Track Popup Menu of MET in Windows 7. Whenever I dragged files from explorer, I can not drop down files to MET because mouse cursor becomes "Unavailable" shape.

So I did same at NPP as a result NPP was the same.

But whenever I ran NPP without "Run As Adminstrator" on User's privilege, I can drag and drop files to NPP and MET is the same.

What's wrong?

Is NPP right or is it errors? If it is error, how can I fix it?

Thank you.

How is that related to C++/CLI? From what you are writing here, it looks like this is not a programming question, just about using of software. Even if you use the editor for writing code, the question is off-topic.

Oh, Sorrry.
I've made mistakes. According to my questions, you said right. I'll improve my question. Thank you.

I don't see any improvement in your question. There is nothing in there that shows what your code is trying to do.

This isn't an error in your code: it's a Windows design feature.
A lower privilege task cannot drop onto higher privilege tasks from Vista on. This is by design: http://blogs.msdn.com/b/patricka/archive/2010/01/28/q-why-doesn-t-drag-and-drop-work-when-my-application-is-running-elevated-a-mandatory-integrity-control-and-uipi.aspx[^]

Ya, thank you.

Then, how can I access higher privilege tasks from lower privilege? Is it possible?

OriginalGriff 24-Oct-13 8:34am

You can't unless you elevate the lower task - this is deliberate, to prevent a low privilege from accessing potential elevation of privilege attacks, and getting access to higher privilege items than it should through a "back door".

This may sound like a silly question, but since when did a text editor need admin privileges anyway? :laugh:

Wahaha..... What a silly boy.
Cann't you access higher privilege tasks from lower privilege?

If you apologize, I could teach you how to access....
