I'm following along with an excellent Scott Guthrie article (MVC form posting scenarios) and trying to convert it to VB along the way. I've got everything working except one piece. At one point in the article he's adding his own business rules to a LINQ to SQL entity like this:
public partial class Product
{
partial void OnValidate(ChangeAction action)

Is it possible to automatically insert a Code Snippet when an interface is implemented? If so, how do you do it? I am looking for something similar to when you implement IDispoable in VB.[code]This will be used by web forms when transfering parameters from one page to the next using Server.Transfer
View 1 RepliesI have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?
Is there any equivalent for Typdef and Void in VB.NET.What I'm trying to do is, I have a function call for DLL in VC++ which is as follows:

how it can be translated in Vb.NET?
I really need little help with unmanaged dll access from VB.NET, have been working on it about a week. I have a C++ .h files with headers. I have to access one function from the dll using VB.NET:
int
acsGetEventPoll (int acsHandle,
void FAR*eventBuf,
unsigned short FAR*eventBufSize);
Documentation says that eventBuf is a buffer where structure of type CSTAEvent_t is put after the function call. Type is defined as:
[Code]...
I need to access a DLL function which has a void pointer argument (probably written in C/C++). In VB6 it could be accessed by declaring the argument as 'Any'. VB2008/VB2010 does not know this variable type 'Any'.
I tried instead: Object, IntPtr, UIntPtr, Int32(), Long e.t.c. but there always occurs a compile error or a runtime error.I did a lot of Internet investigation but could not find any answer.
Is there a solution to this?

I want my vb.net dll to get the data sent from c++ project(exe).Can any body help on in what form this void pointer can be sent via pipe. The void pointer corresponds to enums or structures. I have to get this structures/enums on the vb.net dll end. I have mentioned about using pipe. My question is as what type the pointed to data can be send over the pipe so that I can easily handle the received data at the vb.net dll end.

View 1 RepliesI am making changes to my companies internal paysite in order to come into compliance with the new credit card regulations. We have decided that when we get a split tender transaction that comes through we want to get the remaining balance along with how much was on the card to start out with and send that info back to the customer service rep with a message relaying the need for another payment source along with the remaining balance and the amount that was originally on the card.
Instead of chaining the transactions together with the split tender Id we have decided we would like to finalize each split tender transaction with a prior_auth_capture and then request the next payment source and amount and process that transaction in the same manner. I know that we are side stepping the functionality some but those are my orders.
My questions are, is this feasible and possible and how do you do this in code? I am using the C# SDK to implement this in VB.NET 2008
My thoughts are that I would have to process the transaction for the amount passed as a auth_capture transaction and then some how do the prior_auth_transaction with a zero amount or something?
Can partial classes be used for web-services or there is some other way to implement it ?
View 2 RepliesI have the follow VB.NET class definition:<Serializable()> Partial Public Class Customers End Class
Inside another file I have the same thing (with different methods and variables of course). When I compile, I get the following error:Attribute 'SerializableAttribute' cannot be applied multiple times.The error is pretty self explanatory. My question is though, if I just mark the one class as Serializable(), can I assume the entire class with be marked as serializable()? In other words, Do I only need the serializable() tag in 1 spot in the class?
I have a lot of information distributed among some tables in a database (and must likely it will all be represented into oop). I will need to create text files with different formats from the same data depending on the request. My idea is to create a design that will require no coding if such formats are to change of be added.I was thinking in using some sort of XML magic trick to accomplish this but I have no idea how to. I am also open to new ideas.

We have a big Form class that we like to split into peaces using partial class approach That could be done by manually modifying a project file, and adding MainFormPN.vb entry
<Compile Include="MainForm.vb">
<SubType>Form</SubType>
</Compile>
<Compile Include="MainForm.Designer.vb">

The issue with this approach is when double click on this item in VS2008 IDE it shows new empty form, not MainForm UI. It looks like VS2008 does not support multiple partial classes for a Forms.
I'm still learning so this might be completely wrong. I have built a multi-user web application for internal purposes. I have split my code up to make it more manageable and have run into some problems. I suspect that I have done something very silly!
I have a class in a separate file (quoteStatus.vb) in App_Code here it is:
Imports Microsoft.VisualBasic
Imports System.Data.SqlClient
Imports System.Data
Public Class quoteStatusHelper
[Code]...
This seems really wrong, as the value seems to be held in the partial class after the first run. So if I have two users accessing the class the public shared dim is changed for both users! There must be a better way to do this. I have looked everywhere and I'm more confused now than when I started off..How can I make QuoteStatus in the partial class unique to every user and access it from my code.
I have a bunch of models that contain audit info (CreatedBy, CreateDate, UpdatedBy, UpdateDate). I'd like to create a partial view for displaying this info and then use it for the 20 or so tables. Is this possible?
View 1 RepliesWhen you create a new asp.net page in VS 2008 and choose code behind, it also creates the typical aspx.vb or aspx.cs file to go along with it.
At the top of those files, VS names the 'Partial Class' name the file structure and/or name of the aspx file.
The question: Is there a best practice for this? Can I just use a single class name for all the pages in my application or perhaps a single directory instead of having to give each one a unique name?
I'm using Linq to SQL, which generates partial classes and partial methods. You then extend that generated code by implementing your your customizations manually in another partial class. One of the hooks L2S gives you is the ability to implement partial methods that get called when a property changes. For example, if you have a property named "MyProp", then you can implement a partial method like so:

I would like to create a partial class for my form. I have a lot of events, and it gets messy, so I would like to break up sections into their own files. The problem: When I create a partial class of my form, say:
Partial Public Class Form1
End Class
Visual Studio decides I need another form for this partial class.
1. How do I create a partial class for a form?
2. If I cant do that, how can I break up all the events in my form into different files?
Using vb.net 2003 asp.net 1.1. I have this C# function that I converted and I gettinga squiggley saying full and partial not part of string, this is converted from a .cs file.
Here is the function, maybe I'm not seeing something:
Code:
Public Function RefundTransactionCode(ByVal refundType As String,
ByVal transactionId As String,
ByVal amount As String,
ByVal note As String) As String
Dim caller As CallerServices = New CallerServices

I was following the example laid out here for implementing Ajax panels in MVC. I'm using VB.NET, but the conversion is pretty straightforward. However, I can't seem to get it to work?
Here is my code:
HomeController:
Function Index() As ActionResult
Return View()
End Function
Function Archive() As ActionResult
Threading.Thread.Sleep(5000)
Return View()
End Function
[Code] .....
When I run it, all I see is the ajax-loader animation endlessly. When I run it in debug mode, it never seems to trigger the Archive action.
How do I insert the partial class to be correct?
Imports System.Data
Imports System.Data.SqlClient

I am reading a book (ASP.NET 3.5 Enterprise Application Development with Visual Studio 2008: Problem Design Solution, WROX)The source code is written in C#, but I am a VB guy, so I am giving it a try. Somewhere in the 2nd chapter, there is a Linq to Sql file used that is generated by drag&dropping the DB tables from the Database Explorer. Because some tables have the same type of fields, there is an interface generated called IENTBaseEntity. The writer says its a good practice to implement this interface in another partial class (not the designer.vb file!). The reason for this is that when the LinqToSql file is modified (and regenerated) the changes wont be lost.
In C# this solution is easy to do (i think), but in VB.Net I get an error, because the concerning properties in the LinqToSql file do not append the 'Implement IENTBaseEntity.Property' line. When I press [Enter] after the interface implementation line, VS generates other properties like this
Partial Public Class ENTUserAccount
Implements IENTBaseEntity '--->This line results in the error
' This is not the way it should be
Public Property InsertDate1() As Date Implements IENTBaseEntity.InsertDate
Get
End Get
