Disable The Local Area Connection While Leaving The Wireless Connection Enabled
Jun 21, 2010
I am attempting to write a program that will disable the Local Area Connection while leaving the Wireless connection enabled. My company is using net-books in our stores to demo air-cards and we need to keep them off of the LAN. I'm new to VB and VB.net, and it's been a while since I did any type of programming. I've gathered some code that others have posted in forums and tutorials and I'm working through a tutorial book, but I finally believe that I am stuck.

I have built a client-server VB.net inventory application for our company which connects to our Server machine running on Windows XP. We have 6 client machines running also on Windows XP that connects to the Server's database. Now, my problem is, "How do i connect a client machine running on Windows Vista to our Server running on Windows XP wirelessly?"
- Is there something I have to alter on the SQL Server Surface Area Configuration?
-Or do I have to change the 'Connection String' on my software application so as to properly connect to the Server from a Vista mahine? If then, how?
This is the error its throwing:"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)"

I am currently improving an existing handheld application, this app makes live calls to our network over the wireless connection, if the wireless connection is not established I am displaying a holding screen to the user, this screen rechecks connection every three seconds.I want to put a button on this screen that closes down the application if the user does not want to wait any longer. At the moment I am using the application.exit command, however it continues to finish the first original thread (i.e. trying to process the dataset) before actually closing the application, I am looking for a way to kill the application there and then!

I am using the code below to test whether the user is connected using either a wireless or LAN connection. i.e. that the cable is plugged in, or the wireless is switch off. The code works fine for this. However, if you can spot any potential problems with this or you know of a better way I would be interested to learn more.

The simple line:
Enabled = False
Leaves the user no options to do anything with the program.What I want is to disable everything using the given line (or if anything else), but leave a Menustrip enabled.

I'm trying to a open a connection to a local database and no matter what I try it just won't work (I'm pretty new to SQL Server and VB for that matter) I tried using 'sqlconnection' with different connection strings but none of them worked or gave me any useful error messages so I tried using 'OleDBConnection' instead, this hasn't worked either and it gives me this error instead:"A first chance exception of type 'System.NullReferenceException' occurred in MyProgram.exe"
Here is the code I am currently trying:
Private Sub MemDetailsSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ConnectionString = ("Provider = Microsoft.Jet.OLEDB.4.0;" & "Data Source = Database.sdf")
DataConnect = New OleDbConnection(ConnectionString)

I've been looking over a bunch of code snippets and I'm just not understanding what is going on there.anding the connection, reading/manipulation, and closing pI keep reading all about these DataAdapters, Ole and Sql and Sqlce and I don't know which to use or whatever.I made a database in VB.NET 2010 that came out as database.sdf and I selected the Local Database option (I assume this is relevant?). I then populated the database with a row of data with column titles and a primary key. The table contains many different columns, but for test purposes, the following is relevant:
DB Name: db_test
Table Name: Locations
Primary Key Column Header: CITY

I have finished my program and now i am ready to deploy it. The only problem is it is a multi-user application. All i want to do is simply run the program with the database from a server, and have other local computers with the program access this same database. I know that you have to change the connection strings for the local computers, but how can i go along doing this?

I may be SOL on this but I thought I would give throw it out for possible solutions.I am writing a computer access control service tcontrol my kids' computer use. Plan on open sourcing it when I have it working. It is written in VB.Net and needs to work on XP through 7.I am running into all sorts of security and desktop access issues on Windows 7.The service needs to run as admin to execute the NetSh command to disable the network. But I cannot interact with the desktop from the service so I IPC to a UI to handle other stuff, but I still cannot detect from the service if the desktop is locked. Argghh!

I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.

I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?
