Im working on my first n-tier application. I am trying to serialize a structure and Im getting an error"Soap Serializer does not support serializing Generic Types : System.Nullable`1[System.DateTime]."Here is the structure that is being serialized Namespace Structures

The bold line is the line that is throwing the error.
Is it possible to extend primitive types such as System.String and System.Int32 (IE: integer) in .Net 4 and if so how?
To be more specific, I am aware of the concept of partial classes but this doesnt seem to be the answer. Also I find that System.String is not inheritable and Int32 is a structure.
Lastly I am interested in knowing both a VB.Net and C# answer to the above question.
VB has a feature that C# does not, imported namespaces at a project level (My Project>References>Imported Namespaces). When new people check projects out of source control none of our custom imports are included. Where is this VB specific Imported Namespaces stored?
I am use to VB.NET. The game source code I am learning from is written in C#. I find it annoying that I have to add using System.Diagnostics to the source code in order to type Debug.WriteLine.... I checked under project properties, but I cannot find the References tab that allows me to add namespaces to Imported Namespaces. Where do I find this in C#?
I have imports namespace System.Data.SqlClient.I just create object of SqlConnection,But error is there- 'SqlConnection' is ambiguous in the namespace 'System.Data.SqlClient'.
Function ExecuteAndLogError(Of TResult)(ByVal code As Func(Of TResult), _ByVal sql As String, _Optional ByVal parameters As SqlParameterCollection = Nothing) As TResult End Function
I am getting this compiler error : 'Func' is ambiguous in the namespace 'System'.
I'm currently working on an existing ASP.NET project. At the moment I have to integrate a new componant so for that purpose I had to change the framework target from 2.0 to 3.5. After regenerating the solution, I'm now dealing with a strange issue.
And the last line returns that error 'ScriptServiceAttribute' is ambiguous in the namespace 'System.Web.Script.Services'I have definitely no clue what's going on in my code ?! Is it an internal error of the ScriptService constructor ?
I've created a project which references some other projects in my solution. I've added the references properly to my project (which I've done a thousand times before), and used them in an Imports statement. I can successfully create references to the objects contained in the referenced namespace at design-time but whenever I attempt to build or run the project, I get build errors saying that the referenced projects do not exist. Their Imports statements change to the broken green underline and the only way to remedy the problem is to re-add the references in my project's properties.
I know that the referenced projects are valid, will compile etc... because they work fine for other projects in the solution. Also, I can go to the definition of their objects as long as I don't build/run.
I am creating class libraries in my project so that I can update code without having to update the whole app.I created a class library project and added some code to it. I also added a reference to System.Data.SqlClient and also imported it into the class file.I am getting an error and I have never seen it before. Been looking online and not able to find an answer yet.
can we unzip a zipped folder using microsoft APIs or namespaces perhaps System.IO.Compression. However, it seems to be cumbersome to use them. With a thrid party dll file it works perfectly fine, however i dont want to use it as we dont know what is actually happening inside. Can we have a piece of code which unzips a zipped folder.
I have tried several ways but can not make this work. We are using .NET 2.0
vb If DataGridView1.Columns(e.ColumnIndex).ValueType = GetType(String) Then 'this did not work either: ElseIf DataGridView1.Columns(e.ColumnIndex).ValueType = GetType(DateTime)

I realize AesCryptoServiceProvider is part of .NET framework 3.5. I do have 3.5 installed. However, (I can't believe I don't know this), how can I utilized Framework 3.5 so I can access the AesCryptoServiceProvider? Currently, it points to 2.0.
I have made an simple application (.exe). When i run this program local on my machine it works fine. When i run it from an server i get the system.security.securityexception message.
I'm working on a basic file encryption by using the Imports System.Security.Cryptography.I was thinking of putting a password as a final security measure.Would i have to store the password inside the file or how will this work?
I am trying trite code that will copy information from an infopath document to a word document that is being used as a template containing only a header and footer. The only reason for the code is becausthe footer (not optional) is too long to be handled by Infopath (which has a 255 character limit) and word can hold the full footer. Following the guidance on
Public Sub CTRL1_5_Clicked(ByVal sender As Object, ByVal e As ClickedEventArgs) Dim appWord As Word.Application Dim wrdDoc As Word.Document
I'm working with a vb.net 2005 project that i converted from vb 6.0 last year. It's working fine in windows xp, but on vista and windows 7 i get an error saying 'Insufficient security permissions to set the system time.' Can you think of any way to replicate this error on windows xp? I'm trying to get a windows 7 box setup at work but I was wondering if there was anything I could try with xp in the meantime.
I am getting the error: 'User' is ambiguous between declarations in Modules 'My.MyProject' and 'My.MyProject'.I am trying to debug an ASP.NET web application compiled as a file system project. Obviously the namespaces in question are in-built Microsoft namespaces so there is no way to change anything here nor change any class definitions.
I want to add a feature to my trial version of the application. After first activation, I want to make it limited to 90 days. But I am concerned about user's changing the date of system hence deceiving my application. Is there any possibility to make it fool proof in a way that even if user takes the calender back, application expires after 90 days of first activation? First activation date has been saved in the database.
Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.

Most of the time this works as it should, but sometimes it encodes a string and the gives an error on decoding it. The error message is: Invalid length for a Base-64 char array.
