Need a list of Pcap.Net members or classes? Their website doesn't have much documentation and have looked around in the forums.
I have found..
PacketTs = Packet.Timestamp.ToString("yyyy-MM-dd hh:mm:ss.fff")
PacketS = Packet.Ethernet.IpV4.Source
PacketSp = Packet.Ethernet.IpV4.Transport.SourcePort
PacketD = Packet.Ethernet.IpV4.Destination

I'm writing a WCF-Service and I split up my service class to multiple partial class files, so every ServiceContract-Implementation gets its own file. I have one file however that should contain e.g. members that are used by every partial class file such as a logger. The service is hosted with IIS 7 if this matters in any way.

The code compiles fine, but at runtime I get an BC30451: The name m_Log is not declared Error (Don't know the exact words for it. I get a german message ;) ). I don't think it has something to do with the type of m_Log or a depending assembly because I get the same error if i try this with a String. What am I doing wrong? How can I make this work? Edit: I was trying the same thing in a simple console application without any problems. :(
So say I define some interface, and that interface has members that need to be implemented under some idea, and I then implement this interface on a class that already has those members defined. How do I NOT receive errors about having to implement said members despite them already being implemented (because I didn't type the oh so ridiculous 'implements IMyInterface.foo').
For example say I have an interface that defines the event KeyPress, and then I have a custom Form that implements this interface of mine. It throws an error. VB is the 5th language I've worked in that uses interfaces... and up until now they've all treated interfaces relatively the same. This is the first time I've seen this not allowed. What perplexes me more, is it IS allowed in other .Net languages. Just not VB.

I've read that modules are basically shared classes. For a module though, you can call a method directly without prefixing the module name. So I can do this: methodTest("abc", mod1Enum.enum2)But for a class with shared members I have to fully qualify the method call, and in this case fully qualify the enum:[code]In our conversion from VB6 to .NET the need to fully qualify all calls like this might be an argument for us to bring our VB6 modules over as modules instead of converting them to classes.
View 7 RepliesAt the moment I'm trying to create a kind of model in vb.net which can be used to create/fetch database entrys.
I created a main class Model with a shared function to fetch the datasets, e.g. Model.find(). Now I'd like to create Classes which inherit the main Model-Class, e.g. a separate one for users: UserModel.find() => "SELECT * FROM users".
What I need now is to find a way to tell the Class which table it should use. I thought about an abstract String "table" which is a constant in each "child-model", but how could this be implemented as it's not possible to override shared members?
Edit: Maybe this will make it a little clearer what I mean:
Public Class Model
Public Shared _controller As Controller
Public Shared table As String
[Code].....
So I want a shared method which finds all database entries and gives back an array of instances of its own type, e.g. Model(). That's why I wanted to keep the find-method shared and not bound to an instance.
Im trying to search the entire active directory to look for a group and then see if the current logged on user is listed, then take an action based on that result.So far i have the below code which doesnt return the users who are members of the group MyTestGroup.

im trying to display each line that is stored in the list in a label, and im having major trouble. I know all of the results are added into the lists, but how do i call the list in my main form in order to display each line of all of the values? Would I have to look up an index or something?
If I have a generic.list(of ClassA), is there a simple way to create a deep copy of this list that will not affect the original copy? It seems to work if I have a generic list of Structures, but for some reason the copy constructor for lists of classes only copies pointers to the elements (or maybe a pointer to the whole list?). I would move to structures if it were not for the fact that I can't find a way to edit the members in the structs in the list. eg:list(0).a = 5 'Does not workIs there some way to get around this without declaring an instance of that structure, like this:dim str as StructA = list(0)str.a = 5I'd

View 1 RepliesI have several different lists I want to call. They all have the same format for the class:

Instead of creating a bunch a classes to return the all of the many lists, I wanted to use generics and just tell it what kind of list to return. However, I can not figure out how to populate the classes.
Here are 2 examples of function in my calling code. This should indicate the type of list and the stored proc used to get the data:

View 2 RepliesHow can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
Here is some example code of what I mean:

Public Class Form1
Private Sub Button1_Click(ByVal sender as Object, e as systemEventArgs) Handles Button1.Click

I migrate between C++ and VB.NET in my coding ventures... which leads to the occasional confusion about when something is by value or by reference in VB.NET.Let's say for example that I have an array of MyObject which is populated with a bunch of objects.
dim MyArr(5000) of MyObject. let's say that the information from this array travels throughout various data structures:
dim MyList as new List(of MyObject)
for i as integer = 0 to 5000 step 1000
Mylist.add(MyArr(i))
next
Under the above scenario, I believe everything is by reference. If I extract an entry from "MyTable" and modify its MyObject Members, I think that the original in MyArr will be modified.However, I have run into situations where I thought something was by reference, and it was by value. Are items always added to containers by reference, or are they sometimes added by value?
