I'm working on my first VB2010 project, having used VB6 up to now.In VB6, I used some library functions to implement a treeview of network PCs and their shared folders.
I've been searching, but I've not found a way to get this done with VB2010.
I have found scode to return a list of all the devices local to my network....close but not what I'm looking for.
Does anyone know a way to get a list of UNC servers (A.K.A. items in the "Network" system folder in windows vista +, or "My Network Places" in win xp -), and get a list of shared files for a particular server?
When I try to get directories using System.IO.Directory.GetDirectories("\"), it says I need to put it in the form of \UNC serverFile share
The following statement returns ALL directories in DirPath
"For
Each Dir
In
My.Computer.FileSystem.GetDirectories(DirPath)"
How can I identify those directories that should be excluded from general use, such as $Recycle.bin, System Volume Information
In other words, dulicate the function of Windows Explorer.
How do I get all of the mapped network drives (shared ones) like the ones that a person would see in Windows Explorer? That is,
Network Places
Computer 1
Shared Folder
Computer 2
Shared Folder 1
Shared Folder 2
Is there a command or an API function that I can use to get at least the names of the computers and its folders?
I have a page in VB.NET that is hosted with IIS 7 on Windows 7 Home Premium. The page has code in the Page_Load event that scans through a directory and adds all sub directories to a drop down list. When testing through VS2010, it works perfectly. However, when I set the site up in IIS, the page loads correctly but nothing is added to the drop down list. My current code is: [Code]
View 3 RepliesI am using the following code to add all files and sub-directories to a Treeview control. The user can select a directory (using a folder browser dialog) and this code will add that directory, and all it's files and sub-directories, to the Treeview:

I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.
I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?
I want to have a treeview as directory navigator I can view the first path of my dir (C:Dirmanin), I can list all files in and folders in this path, but I can't add the subfolders as node, and the subfolder of the subfolder...

Below (Example 2) is working code for populating a treeview with directories only down to 1 level. Note just directores are added- No files. I want to add a Listview control beside my treeview and have the Listview populated with the "files" from the selected node in the treeview. This would fire off the NodeMouseClick event of the treeView. I have used Example 1 (NodeMouseClick) before with other code that I have. However, I cannot get the code to work with the Example 2 code below
how to change the Example 1 code to work with Example 2?

I have a VB2008 application that runs off a server. Users connect to the application via shortcut.
[code...]
For what it's worth, the application is targeting .NET 2.0 Framework on both the development side and package install side.
The illustration below is more for my sake than yours, but should help me explain the problem.
User A and B work just fine, but when User C and User D attempt to use the program via shortcut9(same as User A and B) the error below is displayed.

what I can do to allow User C and D to use the application?

View 2 RepliesAll i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.
View 1 RepliesWith the help of NetFileEnum or Openfiles.exe of system32, we can get the username who has opened the shared files. Is there any API function or any exe files in any programming language like c#, vb.net, visual c++ to find out who is the user to create, rename, or delete shared files or folders on the network?

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.

it just creates 1 folder but not other folders with in folder.

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

Basically I'm going to try and develop a software that merges PDFs automatically using the PDFSharp API.What I want in the program is to basically that: Have the program to give and Input and Output directoryMerge all the documents in the directory or sub-directoryRename the merged PDF file according the the name of the directory/sub-directoryIf the folder has PDF files and a Sub-Directory I want to merge the PDF files in the folder and rename them as per the main folder, and rename the files in the sub-folder according to its name (i.e. seperate|)
It's the first time I'm using an API.The problem I have is how to use the directories and sub-directories as I need them.

Given in the following language specification, for me at least, calling Db.Foobar() [In the following code] does not indeed call off to the Shared Constructors of the base classes.

I seem to be drawing a blank. I'd like to create a "shared" variable that is shared with all instances of a class but not classes that inherit from it. For example.Class A: Shared list As New List(Of String): list.Add("A")
Class B Inherits A: list.Add("B")Class C Inherits B: list.Add("C")The end result I'd like is that any instance of A has just A in the list. Any instance of B has A and B in the list. Any instance of C has A, B, and C in the list. I can accomplish it by creating Instance variables, but I have to construct the list for each instance of a class. I'd like to construct it once for a specific point in the Hierarchy and then share it accross other instances of that class.

View 1 RepliesI am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).
