I'm currently trying to create a NEWID() function in my DataContext in LINQ using the solution here, however, when adding the partial class to my DataContext.vb or a separate DataContextPartial.vb, I get the error System.Data.Function is not available in this context because it is 'Friend'.
I've come across this when accessing data types before and that was in easy fix of setting it to Public, but I'm not sure where the properties for function could be or how to change them.The code I have is converted to VB.NET from the C# in the linked answer above:
Partial Public Class CMSModelDataContext
<[Function](Name:="NEWID", IsComposable:=True)> _
Public Function Random() As Guid
[code]....
I am trying to convert this method to VB.NET but the online converters seem to make a mess of converting it. Can someone help:
C# original:
private IEnumerable<IGrouping<string, Reference>> FindReferencesWithTheSameShortNameButDiffererntFullNames(List<Reference> references)
{
[code]....
This errors on Where is not declared.I wouldn't have thought that the VB would not be that dis similar to the C# something like this:
Private Function FindReferencesWithTheSameShortNameButDiffererntFullNames(references As List(Of Reference)) As IEnumerable(Of IGrouping(Of String, Reference))
Return From reference In references
Group reference By reference.ReferencedAssembly.Name
[code]....
But I get: Definition of method referenceGroup is not accessible in this context.
I am having a Friend Class InterceptingChannelBase class.It has a property as below:
Protected ReadOnly Property InnerChannel() As TChannel
Get
Return Me.innerChannelT
[code]....
This class is being inherited by (Friend Class InterceptingInputChannel) class which in turn contains another (Private Class TryReceiveAsyncResult) class.The property above is being used in this private class as below:
Public Sub New(ByVal channel As InterceptingInputChannel(Of TInputChannel), ByVal timeout As TimeSpan, ByVal callback As AsyncCallback, ByVal state As Object)
MyBase.New(channel, callback, state)
[code]....
I am getting the error on the above underlined statement saying that Protected Readonly Property InnerChannel is not accessible in this context because it is declared asa Protected.As far as i think,if i declare a property in class as 'Protected' then if this class is inherited by 'another' class then i can use this property and it should not throw an error.
So what does this mean and how do I fix it? This message occurs if I place the New keyword in the line(s) below. If I remove it, i get an error at runtime saying I need to use New. What am I doing wrong? Code:

If I'm extending OnCreated for a LINQ to SQL table object, is it possible to get a reference to the data context to which the table belongs? For example, if I add a property to the data context:
Partial Class MyDataContext
Private _myValue As String
Public ReadOnly Property MyValue As String
[Code].....
I don't want the property on the data context to be Shared, because it could be different per instance. I've been pouring over the designer code to figure out where the reference might be, but no luck yet.
I am working on a windows application in vb.net 2005 and it needs to connect to the SQL Server database. In this example I testing if the connection is able to open properly:
[Code]...
Is it something dealing with the permissions set with the database server or something? I am new at .NET programming and I have been spinning my wheels on this for the past couple of days and I am at a loss. From what I research, this error should only occur if I was creating a web program, but I am not. It is a windows application.
i am trying to connect to an MS Access database and I am getting an erro message on the following line of
searchtable_command = New SqlClient.SqlCommand(searchtable_string, testsearch_connection)

Here my connection string:

What am I missing?
My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application.

I'm trying to get a generic method working in VB.NET but I can't get the signature to accept a generic type parameter. I just get "'t' is not accessible because it is "Friend"".
My method signature is:
Public Shared Function GetOffset(ByVal coll As IEnumerable(Of t), ByVal offset As Integer, ByVal limit As Integer) As IEnumerable(Of t)
When bulk renaming files (14000 of them) i get this error: The CLR has been unable to transition from COM context 0x4cefd8 to COM context 0x4cf148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
My code is as follows:
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim asd As List(Of String) = FileIO.FileSystem.GetFiles("D:Music").ToList
Dim rs As New ADODB.RecordSet("SELECT * FROM Songs", My.Settings.Files_Database__Connection)

To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations. I've poked around on the internet and on a forum, someone suggested to use application.doevents(). I did that and the messaged goes away. In an earlier thread a member wrote that using application.doevents rarely was used appropriately. Is my situation a proper usage of application.doevents or is there something else I should be doing?
im having some problems using the data adapter. i tried a statement select 1'test' but when i do adapter.Fill(dataset, "tbl1") and tried to read the value from the first row in tbl1.hen i do row(0) i can retrieve the value. However if i do it by the name like sayrow("test") and i would get a dbnull.

I have added a reference to the System.Data.SqlClient, but i am not able to use its components while coding, But when i import it in the form class i able to use the component.
So,Is importing a namespace and adding a reference two different things?
I can't make difference between public class and private class and friend and protected friend class.

I've been reading about access modifiers in VB.Net lately, and there is something that I can't really understand: How do elements in a Class (or Module) inherit the modifiers of their enclosing block?For example, suppose you have a Friend class Bla in an assembly, with a public method Foo:
Friend Class Bla
Public Sub Foo
(...)
End Class
Does it behave differently than when Foo is set to Friend?
Friend Class Bla
Friend Sub Foo
(...)
End Class

I have an issue with FxCop and the warning: Abstract types should not have constructors.This is being displayed for a number of abstract classes (possibly all, I haven't checked). When I look most of them have no new method so I assume it's the complier adding a default one. So to remove it I add a private default constuctor (Private Sub New()), this then means all the inherting classes fail to build with the error: Class 'InheritingClass' has no accessible 'Sub New' and cannot be inherited.This seems odd as FxCop requests no public constructor, but when I remove it the build fails.

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.
