UNC to regular path (not the other way!)

Umm i had another post like this, seems like people still didnt understand what I want:D
I want to convert a UNC path back to a windows path with drive letters in it. How would i do it?
ie, i want to convert \\server\share to "d:" if that share is mapped to drive D on the local computer

MrPolite, that was exactly what the example I posted for you did :(

what about it didn't do what you were saying? you type in a UNC path in the textbox, and the code will look at all your drive letters to see if one matches that UNC, and gives you the drive letter of the match, if present...

Have you tried FileSystemObject.

Probabaly, this function is what you are looking for.

VB Code:

Private Function convertUNCToDrive(ByVal pathName As String) As String
        Dim fileSystem As New FileSystemObjectClass
        Dim pathToReturn As String
        'loop through all drives
        For Each drv As Drive In fileSystem.Drives
            'check if the drive is mapped
            If drv.DriveType = DriveTypeConst.Remote Then
                'check if the share is same as the path mentioned
                If pathName.Substring(0, drv.ShareName.Length) = drv.ShareName.ToString Then
                    'replace it with drive letter
                    pathToReturn = pathName.Replace(drv.ShareName, drv.Path)
                    Exit For
                End If
            End If
        Next
        Return pathToReturn
    End Function

Add a reference to Microsoft Scripting Runtime. And put Imports Scripting at the top.

The wmi sample I had mentioned would do it as well, you would loop all instances of the Win32_LogicalDisk WMI class, see if the "DriveType" property is "4" (meaning Network Drive), then see if the "ProviderName" property (which is the property that lists the network drive UNC path) equals the UNC path you have, then the drive letter is the "name" property of the same object...

I could do a sample that does this if you really need it, but it seems that you have several examples that might work as well...

oooooooh sorry
i dont have visual studio.net.... i was just looking at the API call and judging by what that API call does i thought it's doign the opposite of what i wanted:D

okay it's a start... now i guess i should ask the rest in a different forum. Thanks for the solutions guys. I;m doing this in C++ so i should use APIs only not .NET....
:afrog:

you may struggle the api way, you can sometimes get the GetLongPathName api to work, but it can raise issues over server privilages.
