Getting Permisions

Wamuti

Hi all. When i try accessing drive C: where the O.S.(windows 7), i keep on getting the error: Access to the path 'C:\Documents and Settings\' is denied. and throws the Exception: I have a good idea i have the following piece of code

private static void CopyFiles(string directoryPath, string destination)
{
try
{
int count = 0;
DirectoryInfo dir = new DirectoryInfo(directoryPath);
// DirectorySecurity dSecurity = dir.GetAccessControl();
// dSecurity.AddAccessRule(new FileSystemAccessRule(??);
FileInfo[] wordFiles = dir.GetFiles("*.doc*", SearchOption.AllDirectories);
foreach (FileInfo f in wordFiles)
{

                count++;
                f.CopyTo(destination + count.ToString() + f.Name);
                Console.WriteLine("\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*");

                Console.WriteLine("File name: {0} Copied", f.Name);

                Console.WriteLine("\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\\n");



            }


        }
        catch (UnauthorizedAccessException ex)
        {

        }
    }

I tried to request permisions in the two commented lines but i was totally unable. Please assist. :-(.

yes it will throws Exception because Microsoft replaced "Documents and Settings" folder with "Users" folder from Vista. hence same is the case in Windows 7 then if you want to access the "Documents and Settings" you should looking for Users folder use given Path instead of C:\Document and Setting in Windows 7 or even in Vista

C:\Users

to get more clarification please read the thread of given link C:\Document and Setting[Win 7][^]

Hi, You should never have a hard coded folder name in your app. C:\Documents and Settings\ might not exist for one of many reasons: - your system drive may not be called C: - your Windows system might be an international one using a different language - your Windows system might be more recent than XP and use a completely different folder name. The correct way is by using Environment.GetFolderPath() with the right parameter. That is bound to work on a range of Windows versions starting before XP. See the MSDN doc. :)

I understand. Supposing i wanted to write a file to a drive that is somewhat protected by the UAC, say Windows. This would throw an exception with an access denied message. I have a feeling i should request for permission, then the UAC would pop up, then if would say allow. Is that possible in code. That is really what i want to do. My English is not that good :-(

yes, since Vista, some folders (not drives) are protected. The idea is your app should not write there at all since these folders have special functionality for all users, not just for you. You can invoke the UAC dialog and get admin access rights if you must; see the relevant CodeProject articles[^]. :)
