I want to read data directly into my visual basic application, how can i do it and what resources are required.
I am a student

First, you need a barcode scanner. How you write your code depends entirely on how that scanner works, so dig out the documentation on the scanner.

Help please.. Can anyone there resolve this?
-Sample Code-
System.Net
...
'let's assume there are other codes here
dim Addr as IPAddress
With DNS.GetHostByName(<compname>)
Addr = System.Net.IPAddress(.AddressList(0).Address)
End With
...
That should have been the way to get the IP Addresses, but in VBNET 2003
the line: "(.AddressList(0).Address)" is obsolete.. Anyone knows the new way?? Be grateful for the help..
Thanks in advance..

Since you got that "obsolete" message, you're using VB.NET 2005. Check out the Dns class and its GetHostAddesses[^] method.

Hmm.. but i'm using Visual Studio 2003.. anyways do u know another way? Hope u can help me.. i'm still lookin for another way though.. Thanks

There's only two methods. The one you posted in your code, which gave you the obsolete message, and the one in the .NET Framework 2.0. The .NET Framework 1.0 and 1.1 both use the same Dns class. It was nearly completely re-written for .NET 2.0.
This[^] is the docs for the 1.0/1.1 version of the Dns class.

" 'Public Property Address() AS Long' is obsolete: 'IPAddress.Address is address family dependant, use equals method for comparison.' "
That's the whole statement of the error. My framework is 1.1, and it cant be 2.0 coz im not using VS2005.. but can i use Framework 2.0 with VS2003?
i haven't found another way..and how can i set the client to look for any server running in any of the pc in a network. Like if i run a Server or the listener on PC4, the client is on PC1, without specifying the IPAddress where the Server file is running.. if i transfer the server to PC8, the client can still detect it. Something like that.
I'm actually new on using System.Net and im just lookin on examples available in the web.
I have tried the basics of Server-Client, the problem is the one i stated above. and the client issue.. thanks

OK. So you're using 2003. No, you can't use .NET 2.0 with VS.NET 2003. It will only work with VS.NET 2005.
Remove the .Address part of the line. You don't need it unless you want the IP address returned as a 32-bit number. This isn't supported in .NET 2.0, so don't use it.
This code works just fine:
Dim hostInfo As IPHostEntry = Dns.GetHostByName("www.yahoo.com")
Dim address As IPAddress() = hostInfo.AddressList
Dim al As String() = hostInfo.Aliases
Debug.WriteLine("Host name : " + hostInfo.HostName)
Debug.WriteLine(ControlChars.Cr + "Aliases : ")
Dim index As Integer
For index = 0 To al.Length - 1
Debug.WriteLine(al(index))
Next index
Debug.WriteLine(ControlChars.Cr + "IP address list : ")
For index = 0 To address.Length - 1
Debug.WriteLine(address(index))
Next index
and was taken directly out of the docs for Dns.GetHostByName in the .NET 1.0/1.1 docs.

You said the other PC does not have VB.NET 2003? It might not have the .NET Framework.. so you'll have to install "dotnetfx.exe". It can be downloaded at microsoft website.. search for it..
www.microsoft.com
And if you have a database with SQL server.. you will have to setup a SQL server on that PC.. a client i suppose..
goodluck

Private Sub _SplitterMoved(ByVal sAs Object, _<br />
ByVal e As System.Windows.Forms.SplitterEventArgs) _<br />
Handles SplitContainer1.SplitterMoved<br />
<br />
For i As Integer = 0 To Me.TabControl1.TabPages.Count - 1<br />
Me.TabControl1.TabPages(i).Refresh()<br />
Next<br />

End Sub<br />
Is there a better way to fix the tabpages not filling the tabcontrol's area when you move the splitter?

i have developed an application in vb.net & i want to make my application as start-up i.e when the system will be on,the application will automatically run by itself.no need to double click on the desktop icon.
any suggestions in this regard will be appreciated

When your creating the Install write a shortcut to the .exe into the start-up folder.
In VS 2005:
In the File System >
Highlight the File System on Target Machine >
Right Click > Add Special Folder > User's Start-up Folder then Enter
This will allow you create a shortcut to User's Startup Folder.

hi
thanks for your valuable suggestion.
can i adopt the same procedure to implement the said facility in a set up file so that whenever i load the setup in the target machine,it will ask for a provision that where want to install(like start-up folder,program files,etc..) & accordingly it will got installed in the target machine
any suggestion will be deeply appreciated

I have an application with several objects which I use to store the data that the user entered. Just like any other application (Word, Excel, etc) I need to save the data entered by the user on the disk, and later if the user wants, he/she must be able to retrieve the data and continue working with the application. (Basically, an open&save functionality)
Not all objects that I am working with are serializable, because I use a lot of collections in my classes, so I gave up on the idea to save them as xml (serialized objects).
My question would be, how do you suggest me to save the data of my application and how to retrieve it later? Which is best file class or file format to be used in this case? I would rather save in a binary format than in a text format, so people can't see and change directly the data.
Thank you all

You can use a BinaryReader and a BinaryWriter to read and write simple data types. For classes and collections you have to read/write each member.

I have a data grid that I have bound some data to from a DataTable and the problem I'm having is with the column widths. I've tried to explicitly set the width for each column but have had no luck setting the desired width of my DataGrid's column widths. I believe the issue is because I have some hyperlinks in the DataGrid that are long and they do not wrap. I am curious if somebody has a solution or suggestion to forcing a hyperlink to wrap and how to get access to that hyperlink in the code behind.

I have a user control I created. It has 3 text boxes internally.
My app has an array of 20 of these controls. I need to be able to use
cut and paste to/from clipboard. I keep getting an error message stating
that the control is not capable of this type of operation. The control has
a transparent background.

C# and VB.NET are not good candidates to write drivers like this. You won't find any exmaples unless you write it in VC++.
