Question

I have made a application that can copy files to places in two TreeViews and that has to map your C:. But my father, an experienced programming, said that if the program goes wrong, it could mess up the whole C: of my consumers (I will be publishing this, it is not already out). And as a user, you have to run as admin. How do I make the copy and delete transactions safer (I already have a “Are you sure you want to delete the files?” MessageBox). And how do I make it so that everyone has permission to browse the C:?

Aparently this line of code give me an “UnauthorizedAccessException “
DirectoryInfo[] dirSubs = dir.GetDirectories();

Answer 1

You can do a simple Ok/Cancel or Yes/No prompt using the MessageBox class (see link for sample code).

As for checking permissions I think you want Directory.GetAccessControl. It should be able to tell you if your destination path is writable.
