How do I determine a mapped drive's actual path?
So if I have a mapped drive on a machine called "Z" how can I using .NET determine the machine and path for the mapped folder?
The code can assume it's running on the machine with the mapped drive.
I looked at Path, Directory, FileInfo objects, but can't seem to find anything.
I also looked for existing questions, but could not find what I'm looking for.
I am trying to create a function to convert a mapped drive path to a UNC path. I did some googling and found several different pages on the matter. I am most interested in the first one, but I cannot seem to get the code to cooperate. Since the original post was in C#, here is my VB.NET conversion:
[Code]...
We are getting a new server and we already have a Z: drive mapped, and we want to use the same letter and just change the path without touching all machines. I am looking for a simple VBscript to do that. I have one that will remove and one that will add, but I need to have on script.
View 1 RepliesI was expecting this to be easy but it seems that it is not... all I want to do is loop through all drives on a computer and if the drive is a network drive then get the UNC path that this network drive maps to. Simples. I was expecting to just do this:
vb.net
For Each drv In IO.DriveInfo.GetDrives()
If drv.DriveType = IO.DriveType.Network Then
MessageBox.Show(drv.RootDirectory.ToString)
End If
Next

I am having problems verifying that the drive is mapped. The code I have is this:For the Public Class I have this:
Dim wshNet As New IWshRuntimeLibrary.WshNetwork
wshNet.MapNetworkDrive("Z:", "\\10.21.2.218\Share", True, "wecon\sophosuser", "soweco")
To remove the drive I am using:
'wshNet.RemoveNetworkDrive ("Z:\", False, False)
What I am looking for is how to verify that the z drive is mapped, and if so then run the unmapping drive command.When I try to use a if wshNet. anything the stupid thing won't return a true or false value?I searched all through the net to find some sort of If drive mapped = true, however nothing comes up that I can implement.
I read about the UNC path, but that doesn't seem to be making much difference, it may be that I need a user name and password for the connection, can anyone demonstrate code that allows username and password entry so that a file can copy to and from a mapped network drive or the UNC is "\serverarchiveJune"
View 1 RepliesI have an application that sends files to a Network drive that has been mapped as the "Z:" drive. When code first runs, it errors with "path cannot be found". Then if you open up MyComputer, and double click on the drive, windows asks you for UserName/Password. Once entered, if you run the code again, everything is fine.
So it looks like it cant find the drive b/c a username/password has not "unlocked" the drive yet.
How do I get vb to unlock the drive so I may transfer the file?
I found some stuff online but it seems like it self maps the drive. I'm just looking at applying the username/password to the mapped drive so I may copy.
I am working on a win application that maps/unmaps network drives. And i have a couple of problems getting and setting a mapped network drive's label /name. The driveinfo volumelabel property will get or set the label of the remote drive/folder, what i need is the mapped network drive name/label on the local system. it then adds the driveletter, volumelabel, and connection state to a listview.

my first question on this board. I'm creating a media player(Like so many others). I try playing files over my network. When I pass this address "M:songssome artistsome song.mp3" to the windows media player control it actually opens "\ServerMEDIAsome artistsome song.mp3". But when my program checks if it is playing the correct song it thinks it is not, because the strings aren't equal. Is there a way in VB to get the network address of a mapped network drive? I can already see that it is a network drive but not wich address it points to.

View 2 RepliesI am trying to run a visual studio 2010 app from a windows 2003 server machine that writes xml files to a folder stored on a remote windows 2008 server. I mapped the server drive and can access the folder manually but in the code the 'access is denied' error is hit when the file path declaration is hit for that 2008 server folder. I checked the access writes to that folder and made sure it is shared for that user. Also the user I am logged into on the source server has admin rights so should it not be able to access the mapped drive through the application?How do I grant my app access to that or any folder on that drive on the remote server? I had this issue before but cannot remember what I did to clear this up.
View 1 RepliesI use the following code to layout network drives on a system. I want to add a third column for persistence but in vb.net I do not know how to check if a drive has a persistent map or not.
For Each drive_info As DriveInfo In DriveInfo.GetDrives()
If drive_info.DriveType().ToString = "Network" Then
With maps.Items.Add(drive_info.Name)

I spent quite awhile trying to figure this out and not one single combination of path strings let this happen.
I usually error'd with the path is not found, part of the path could not be found, or wrong user name and password.
All I am using is the <asp:fileupload>.
I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code:
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work
Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
I had a basic text file reader/writer program that wrote and read from a mapped, shared drive up and running for a couple weeks. I wanted to add just a couple more things that shouldn't have effected the program (the ability to write another text file), and now the program can't find the shared drive. The error I get is: Could not find file '<file location>' with <file location> filled in with either the mapped name of the drive (X:) or the unmapped name (\servercomputer). Both are copied directly from windows explorer, so I know the path is right. I'm a bit of a beginner, but I'm pretty sure that all the required permissions are in place, and all users have access to this drive.
To further complicate things, it is not consistant. Some commands appear to have no trouble reading off the mapped name, but don't read the unmapped name, and vice versa. Others won't take either. Sometimes the code will execute perfectly up to the middle of the code (accessing the shared drive a couple times), and then it will give this error. If anyone could point me in the right direction,
Does anyone know if there is a way to determine if a drive is local or a network drive?

View 4 RepliesI am unable to run batch file that is located in mapped network drive using System.Diagnostics.Process in VB.Net. I get:'<batchfilename>.bat' is not recognized as an internal or external command, operable program or batch file.Press any key to continue..I get the same error when navigate to the folder (using explorer) that contains this batch file and double click it. I can successfully run the batch file by changing the directory to that folder through command prompt. I can't figure out why this is happening. I think the problem is Start() function of Process works like double click rather than just run the batch file.

I am converting a VB.Net application to C#. Everything else is going great. Except this bit. I have a function which builds menus,sub menus and seperators from a database. It can build a MenuStrip or a ContextMenuStrip which can then be assigned to a form.
This means that menus can be extensive and conpmex but managed outside the application, which I also use as part of my security access model. All menus are controlled from the database externally, it also means I can develop visual tools (Treeviews etc) to manage user menus. The application uses menus extensively which is by design.
Programmatically I want to assign an eventhandler to every item that isnt a dropdown or a seperator
In VB I would do this, (works perfectly)
[Code]...
"System.Windows.Forms.ToolStripItem' does not contain a definition for 'DropDownItems' and no extension method 'DropDownItems' accepting a first argument of type 'System.Windows.Forms.ToolStripItem' could be found (are you missing a using directive or an assembly reference?)"

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

I am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.
Here is the code:

I also want to know alternative way to get unc path of drive that is also not depend on windows API. As there is a class driveinfo to get all drives (including network) on system. Is there any class that also provide complete or unc path information of Drive.
