Can't Find Intrinsic "Server" Object In A Program
Dec 16, 2009
I have a couple of NET 2.0 projects on the go, but in one of them, I can't access the "Server" object to get at its HtmlEncode property. i.e Server.HtmlEncode("xxx") does not work.
I get the following error displayed in Visual Studio design time error log: "Local variable 'server' cannot be referred to before it is declared."
I have tried to add a manual reference to System.Web, but although the dll file is present, it doesn't add itself on - or at least it doesn't display on the "Add Reference" dialog as being added. BUT here is what's interesting - I can access other intrinsic objects such as "Request", "Response"...etc. All except "Server"!

In other projects, I can access the "Server" object just fine.

That is the question. Is there anything you can do with c++ unions that you can't with c# Explicit structs?

But when I moved my compiler definition to a separate DLL, I the ToObject method was no longer available from my project even though I had referenced the Class project which now contained the extension. Is this a limitation of the Compiler Extensions? HOw do you get reusability out of them?

After reading all the examples for list of T exists and Find and find first, none show how to handle multi-property objects. Below is bare bones example maybe someone could flesh out to show how this should be done.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DatePriceList As New List(Of DateAndPrice)
DatePriceList.Add(New DateAndPrice(Date.Parse("1/1/2000"), 10.12))
DatePriceList.Add(New DateAndPrice(Date.Parse("1/2/2000"), 11.12))

Multi-User Chat Program (Server & Client) with Main Server?

Oct 26, 2011
I made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.
My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?
Second question: can I make a single program where I run both TCP client and TCP server at the same time?

Is there a way that I can parse through the objects of an application and determine if each one is TypeOf a particular form object? I have found no clear way getting a reference to forms that have already been opened. Complicating this further, it appears that not all Visual Basic commands are available to me when coding for an old PocketPC device.

This Questions has properties QuestionID and QuestionAnswer. While iterating through this List of Question in foreach, I have to find .QuestionID = 12. If I find .QuestionID = 12 then I have to immediately assign a value to .QuestionAnswer = "SomeText" of .QuestionID = 14.
I don't want iterate again inside .QuestionId = 12' to find.QuestionID = 14` again.
Is there any way I can go directly to .QuestionID = 14 using LINQ?[code]...

There a dictionary object that gets loaded with the following key values:
[Code]...
In most situations, life is good and all the individual key values are needed/unique. But in certain situations, the keys with letters behind them (ie...189a, 189b, 189c) all mean the same thing (ie...189). So I need a way to see if a key value exists (like the containskey method) for only the first part of the key and then return true.

I am using the IndexOf function of the string class to find a specific instance of a string. And based on that I have a logic to do something. Below is the example of what I am doing. The code is in production and is working fine. But for some instance I am getting an "Object reference not set error". Yeah its intermittent.The requestXML is a string of xml data passed in as a paramter to a subroutine. I am fetching the xml string as a form post in a request object. The only thing I could think of getting this kind of error is when the requestXML string varia

I'm need of some way of finding the UNC Path of a share via a script or command line or even a custom created program. I'm trying to automate deletion of users and the setup is a bit complicated.
Home folders are set up like this:
We create a folder on a Disk on a fileserver.When this folder is created, a share is automatically created on a lower levelThen the DFS Links are set up towards the newly created share.
Now, when deleting a user, I could just delete the DFS Folder, meaning that the target folder is the one being deleted. But since it's a share, that cannot happen.

This starts with an object being added to a collection with: CommonArgs.Add(ObjName, Me)
ObjName is a string, call it "Obj1". Me is an instance of a class inheriting from UserControl. Call it "Class1".
Now, to check the value assigned to Obj1, the vendor has the
Dim Obj As Object = CommonArgs(ObjName)
Dim Info As System.Reflection.FieldInfo = Obj.GetType().GetField(ObjName, System.Reflection.BindingFlags.Public Or System.Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.IgnoreCase)
Obj is the Class1 object added to CommonArgs.
When I run this in my test app, Info is Nothing-but when I run it in the vendor's app Info is an Enumerated type. Why?
I've found a little more info, but it's still a mystery to me-and so far it appears to be a mystery to everybody else, too.
First, I noticed that I didn't mention that the Collection is a Hashtable. I don't know if that would make a difference, but it is something I forgot to mention.
Second, there's a 'regular' variable named ObjName that contains the value being returned by Info. My understanding is that there's no connection between these, e.g. Dim X as Integer = 1 doesn't change the type or value of the object of CommonArgs("X"). But that's what appears to be happening.
Any suggestion?

Basically, I've got this plugin-based application I've used all the time in VS2008 flawlessly. In my current project (VS2010 by the way) I wrote a plugin for the application and whenever I try to use an instance of a particular class (in an external dll) from my plugin, I get an error.
I tried watching the instance and I got the message:
"Cannot find the method on the object instance."
in the watch window. This has never happened before! I also found that some of the extension methods in the plugin does not work.

I'm trying to port an ASP.NET 4.0 data-driven app to a VB Express 2010 Windows Forms desktop app. The ASP.NET 4.0 app uses a SQL Server 2008 Express database and works fine. I can change/add/delete data in the db with the web app, and I can use SQL Server Management Studio to modify the database, but when I try to establish a connection to the same database with the "Add new connection" wizard in VB Express 2010, it tells me that it cannot find the SQL Server Data Provider .The SQL Server provider MUST be installed because otherwise the web app wouldn't work, right ?
