getting mapped drives

[AnuSumesh]

Hi all,

I am writing one application using c# in which firstly I m getting impersonating the user and then i want to retrieve mapped Drives.

But issue is when I am calling method in following sequence:
1. create object of class
2. call mappeddrives() method
3. call impersonate method

then its working fine.
But if i m calling impersonate method before calling mappeddrives() then its not giving me list of mapped drives.

my code for getting mapped drives is :

public string MappedDrives()
        {
            string drives = "";
            DriveInfo[] allDrives = DriveInfo.GetDrives();

            foreach (DriveInfo dirInfo in allDrives)
            {
                if (dirInfo.DriveType.ToString() == "Network")
                    drives += dirInfo.Name+"?";                           
            }
           return drives;
        }

Can anyone tell me the reason behind this?

Thanks,
Anu

Impersonating a user does not run their login script, where mapped drives would be created?
Just a guess

[AnuSumesh]

im not creating mapped drives. just retrieving the list of mapped drived.
And one more point - when i deployed my application in IIS, its not gibving me mapped drive list in either case.

Thanks,

Mapped drives are mapped when a user logs on. If the user has not logged on, the drive is not mapped.

[AnuSumesh]

sorry i did not understand.
u m running my application in visual studio before calling impersonate method then its giving me all mapped drives.

[Plater]

Before impersonating, it is running as the logged on user. That user's drives have been mapped since the logon script was executed

[AnuSumesh]

but logged on user and impersonating user are same

[Plater]

but logged on user and impersonating user are same

Ok, now we're getting somewhere (although that throws my idea out the window)
So if you are logged on as userA, you can see the drives, then you tell your program to run impersonating userA, and you cannot see the drives?
Now I really don't know what to suggest.

Have you tried getting the mapped drives with a WMI search?
[code=c#]

ManagementObjec tSearcher searcher = new ManagementObjec tSearcher("root \\CIMV2", "SELECT * FROM Win32_MappedLog icalDisk");

[/code]

[AnuSumesh]

No.
can u give me link how to use wmi for getting mapped drives?

I recomend the WMICodeCreator tool. Very usefull and it creates sample code for you

[AnuSumesh]

i have tried with this tool also. result is same. means giving mapped drives before impersonation only.

[AnuSumesh]

I have solved by using "Win32_MappedLo gicalDisk" its working.
Thanks a lot.
But i have to try same via IIS also b'coz viz IIS nothing was working.

Can you Please help me in writing code in C# for supporting Double Byte Character support for the same application?

That is really a different question, but I imagine it has something to do with the declared locale and you can probably use the various UTF converters found on System.Text.Enc oder

[AnuSumesh]

Thanks for reply. I am using the same system.text.enc oding but please guide me how i can test for the same on my window xp machine (For japanese)?
