Use System.Net.NetworkInformation.GatewayIPAddressInformation Class?
Oct 1, 2010
I tried every trick in the book, creating a new object, instantiating it (even tho it says i can't) and just trying to create a reference to use it, and then also trying to call the .Address value inside it while using it like i would use a shared member (without instantiation) and nothing is working, msdn sample/help is useless... i even tried inheriting it and useing it like that, none of them worked, i am sure i am missing something, can anyone give me some code samples? here is the msdn docs on it to to give you an overview.url...although i like vb.net more i can read and coded in both c# and vb.net so either will be fine.url...

Is there any way I can do this
Dim ipv4Stats As System.Net.NetworkInformation.IPv4InterfaceStatistics
ipv4Stats = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces(0).GetIPv4Statistics
TextBox1.Text = ipv4Stats.BytesReceived.ToString / 1048576
TextBox1.Text = FormatNumber(TextBox1.Text, -1)
But for a specific program that is running? Like Iexporer, or Explorer, or whatever, is it posible to monitor the packages being recieved by only one program?

I must be missing something very obvious...Using Visual Studio 2005 to write a vb app for Windows CE. I'm trying to use the NetworkInformation namespace of System. I can see it in my object browser, but when I try to use it in my form, it doesn't come up in the autocomplete and the compiler complains that "NetworkInformation is not a member of Net".

When I do this
Public Class cInherits : Inherits Panel
I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
How do I inherit?

I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?
Public Class Rectanglar : Inherits UserControl
Public BackgroundColor As Color = Color.Blue

I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

Code: Dim dom As New DOMDocument30 dom.async = False
dom.Load(serverAddress & "/App/filelist.jsp?type=content")
For i = 0 To dom.childNodes.item(1).childNodes.length - 1 downloadfile(dom.childNodes.item(i), mcount, currentpath) Next
The above code is activated upon clicking of a button. i have the server address declared. and using the domdoc to load the jsp file to generate the xml data. and using for loop, i call the download file function which accepts the following parameters
Code:Public Sub downloadfile(ByVal domdoc As Xml.XmlNode, ByVal totalcount As Integer, ByVal currentpath As String)
The totalcount and currentpath work fine, but when i pass in the dom.childNodes.item(i) , error pops up.
--------------------error message------------------------------------------Unable to cast COM object of type 'System.__ComObject' to class type 'System.Xml.XmlNode'.

I'm trying to use system.io.packaging to create my own zip class. I've got it to work, but i'm not happy with the compression rate. In the code below I've set it to the maximum compression rate, yet winrar is able to create a zip (at maximum compression) that is 2/3 of the size when I make it. Am i doing something wrong?

System.String is a class type, but why we can use it without instantiate it with New keyword?
For example:

I am able to query/read the "Application" event log using System.Management classes in VB.net 2005 (win xp)But I have problem reading the "Message" / "description" of my custom event log.I am getting a System.NullReferenceException{"Object reference not set to an instance of an object."} while reading the "Message" / "Description of the event log while it is reading the others properties.Also when I use System.Diagnostics.EventLog and read all the Events on by one I am able to read the message/description of my custom event log. Why is that the System.Management classes can't read the my custom event log messages while the System.Diagnostics.EventLog classes can read them.The reason I want to use System.Management classes is bcoz I can query my custom event log where as with System.Diagnostics.EventLog classes I have to read the whole event log.

This has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:
somethiing._DEfault is not allowed here because it does not extend class 'System.Web.UI.Page'
where something is the name of the project in the properties. I have the following code in Default:
Namespace FormDiscovery
Partial Class _Default
Inherits System.Web.UI.Page
Shared settings As New System.Configuration.AppSettingsReader
[Code].....
Now I have deleted the project and other in the solution and created a new one and still this error and if I take the 'something' name away I get the cannot load default error.

I am a *** programmer and cannot make sense of the error message I'm getting. I wrote a program and it runs fine on my development machine and also on other machines with Visual Studio installed. However, when I run it on any other machines, I get the message below.All of my other programs that I write run fine on these other machines; so I know this problem must be due to some control that's unique to this new program. But I can't make much sense of the error report
