Cannot Find The Intrinsic "Server" Object In A .NET 2.0 Project?
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" This is only happening to 1 particular project. 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?

I defined the following extension of the Date? data type
[Code]...
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))

I am trying to update a Vs2008 project to vs2010. In one of my projects I have two controls. The controls are not being seen by the form when I open it up in design view. They are friend controls. (No code has changed since I opened it up in vs2010.) But it was running fine in vs2008.

I am working on a WPF project in Visual Basic. In some textboxes I want to limit what the user should be able to type. The sub roughly looks like this:
Private Sub Intervall_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles Intervall.KeyDown
'Determine whether the keystroke is a digit from the digit keys on the top of the keyboard.
[Code]....
If the I type backspace or delete, keydown doesn't react, so these particular cases I've handled in KeyUp.
There are two problems with this code: The test If e.Key < Key.D0 only checks whether the user has pressed the key that contains 0 at the top of the keyboard. It is also possible to enter some other signs if the user presses shift, and this test doesn't discover whether the user presses shift. I therefore need to extract the actual character that the user entered, not only which key he or she entered, and check if this character is a legal one. This is easy in a Windows.Forms project; there I can use e.Keyvalue, but in my WPF project I don't get that alternative when I enter a dot after "e".
It's necessary to solve this problem in order to do the next step: The user should also be allowed to enter colon, as this textbox describes a time that an action should be performed. If I could check the content of the key pressed, this would be easy. The problem is that the test If e.Key = Key.OemPeriod returns true whether the user pressed shift or not, i.e. whether the user entered a period or a colon, which are on the same key on my keyboard, I don't know how it is on other standards of keyboards.
I have tried hard to find a solution for this on Google, [URL] and MSDN, but I haven't managed to find any articles or topics about this particular problem. Does anyone know how to do this in a WPF project?

I am having a problem running an Excel/VBA program that has been working till this morning. The error I got when I ran a macro I wrote is: Compile error: Cannot find project or libraryWhen I check the references in VBA editor, I find the list of references to be different than when I ran it on another machine. I have some xla libraries on a server that I've linked to the application, and the libraries are being shared among my colleagues. I tried relinking the libraries but that didn't work either. Sometimes, I get another message saying the library is being used by another application.

In my project there are lot of variables, and some of them are not used at all.I want to clean up the code by removing these unused variables. These variables are not shown as unused when i build the application. The problem is with the global variables, and not with the local varible for a function .Is there a method to find these unused variables?

I've just converted a project from .net 1.1 to 3.5, and I'm being given loads of warnings in the error list. The program compiles and runs ok, but I think I should probably try to at least reduce this large number of warnings.The trouble is that the error list only tells me about the first 102 warnings. Even when I fix one, the number stays at 102. So I have absolutely no idea how many warnings there actually are. If there are 150, I'd like to get rid of them. But if there are 10,000, I don't have the time to fix them all.Is there a way to see the actual total number of warnings?

I am trying to publish a project. Via the publish wizard I have published the project. So I have:Project.applicationSetup.exeand a directory application files in which:Project.applicationProject.exe.deployProject.exe.manifest. When I start the setup it does it's thing (only one question: do you want to install ...etc) and 2 seconds later its done.
Problem:
1. I can't find the installation directory... (I can find the app in the 'add/remove programs' but not anywhere in program files or ..)
2. there are a few xml and mdb files I want to include in de project (or else the project does not work).
But because of (1) I don't know where to do so. Or beter yet, I would like to include these files in the installer.3. Why doesn't the installer ask me where I want to install?

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.

I am using VS2010 VB.NET, working on a solution that has a number of projects. I have been developing on it for a while now, and in an attempt to debug a custom class inherited from ObservableCollection (which by the way would not load symbols when debugging even though it was apparent that the breakpointed line was being called), I changed the startup object for the startup project to a different WPF window which I had a couple of controls that I set aside for debugging.Immediately I was confronted with 'Sub Main' was not found in . I tried changing the startup object back to the normal startup window, but now the Startup Object dropdown only has "Sub Main" as it's only option. I changed the StartupURI back in the App.xaml, to no avail.

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.

The application must have basic functionality as to: Insert new customers into the database A search function will be needed to find a users criteria entered The more advanced features would include matching certain criteria with another for example if the data in field 1 is the same then it should match this and return the results. so for example if a person has a hobby of 'football' it will return all the people with the same hobby

I support applications in VB6 and VB2003, and I'm trying to upgrade the VB6 app to VB2005, so I have three versions of Visual Studio on my pc. I ran VS2005 and opened the VB6 app to launch the upgrade wizard. It seemed to run fine until it threw an error saying it could not find the project it just created. The project I'm trying to upgrade is called MGxFromSAP.vbp. The error said it could not find MGxFromSAP.vbproj. The project file it actually created is called MGxFromSAP.vbproj.vs7.vbproj. When I try to open this project in VS2005 it says it was created in an earlier version of Visual Studio and needs to be upgraded.Did it perhaps invoke the VB2003 upgrade wizard instead of the new one? How would I be able to tell?
Should I just let VS2005 upgrade the vs7 project or should I try to deinstall the old VS2003 upgrade wizard and rerun the upgrade from scratch?

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
