Create A Read Only Accessor?
Jun 5, 2011I have created getter setters before. But how do I make a read only accessor in VB.net? I want a value to be read, but not to be set.

Generated Database Accessor Code?
Oct 21, 2010I'm trying to make alterations to an existing project, and I've found a project in the solution which is full of generated classes.Problem is, nobody here can tell me what generated them, so I'm pretty much left with pasting one of the classes in here and hoping someone will be able to tell me where they came from.
The solution I'm working on uses Expression Blend 3 and Visual Studio 2008. Dunno if that's relevant, but I'm trying to give as much information as I can think of... As well as this class, which appears in its own file, there's an "SPResults" file, which contains about 5000 lines of accessor classes of this type. Not quite sure why EndCustomer is in its own file...
From what I can see for myself, there's a stored procedure in one of the databases this program links to, and that SP's name is "GetEndCustomers". Something has then created a class called "EndCustomers" to represent the return type of this procedure.
The first part is a function from a class named Database, which returns a collection of the objects in question.
<FunctionAttribute(Name:="dbo.GetEndCustomers")> _
Public Function GetEndCustomers(<Parameter(Name:="Dummy", DbType:="VarChar(1)")> ByVal Dummy As String) As ISingleResult(Of Data.EndCustomer)
Dim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod, MethodInfo), Dummy)
[Code]...
So, yeah, can anyone tell me what has been used to generate this class? It could be something in Visual Studio, Expression Blend, SQL Server Management Studio, or some obscure bit of software I haven't even noticed is on the PC. Any clues, anyone?

.NET - Use A Property Versus Variable + Accessor Function?
Nov 2, 2009Is there ever a situation where I should do the following in .NET instead of using a property with read/write capability?
private S as string
public function GetS() as string
[code]....
Do properties simply provide a more efficient way for doing the same thing?Will properties be any slower than the above accessor functions in a high performance application?
The Method 'X' Is Not A Property Accessor (Linq / LinqToSql)
Feb 15, 2011I'm using LinqToSql classes in an ASP.NET website and let's say I have an entity named Testimonials. Two pages utilize this type - the first being a list of all existing Testimonial records and the second being an add / editor with which to manage the records. [Code] This allows population a DataGrid with the returned items, however on the add / editor page we alter the query ever so slightly: [Code] This query dies, prior to even trying to populate anything, with the following message: [Code]
I have pretty much identical methods for other data objects which have been and still are executing just fine. One immediate difference I can think of is that this table has been recently updated in the database, removed from the dbml designer and re-added to the dbml designer. None of the other tables have undergone this process for some time. [Code] Why is this exception occurring and how can I configure my project appropriately to correct the issue?

Read In A Load Of Addresses From A Database And Then Use Word To Create Address Labels On An Avery Template
Mar 11, 2010In my VB.Net app, I want to read in a load of addresses from a database and then use word to create address labels on an Avery template L7163 which is then printed to the printer.
However, I have two issues:
1. Before word prints, I'm asked to select the printer etc. not exactly the nice automated application I was looking for.
2. Even though I get a nice printed out doc I was looking for, I also get a nasty looking error at the end which "loops" until I close my app -2147417848: The object invoked has disconnected from its clients. (Exception from HRESULT: 0x800010108(RPC_E_DISCONNECTED))
