I need to throw together a quick CRUD asp.net site, but this may become a bigger application down the road. I have some experience with SubSonic, but it has been so long since I did a project with it I have to relearn it. I am also considering using Dynamic Data.

What are the improvements in vb.net compared to vb6 that make developing such an application easier?
View 3 Repliesa friend of mine wants to create a simple inventory database that can be deployed on the web.He has had a lot of experience with Database tools like Paradox. Moreover he has experience with writing Macros and programs with Basic, and even a bit of C++ experience. He uses Windows and Mac OS X, though mostly Windows.
If the requirement of having a web application wasn't there I would recommend MS Access.

So I'm developing an application in VB2010. The idea is to perform CRUD operations (more or less) to an Access2003 Database. The database is relational, yet I haven't grasped the best architecture to make an application to interact with it. I tough doing a Business layer with a domain model would work. Controllers for each Use case (which are basically CRUD operations) would create Domain Layer object. Yet I don't know yet how to manage the mapping of the objects to/from the database.
View 8 RepliesI am using Subonic in a VB.net application for the first time (I have used it succesfully in a WebSite project plenty of times). I followed the 2nd part of the 'Getting Started' video to actually generate the DAL source files as opposed to the build provider method and everything APPEARS to have gone like expected. However, nothing I do will get my generated namespace to appear. I feel that it has to with the fact that I am running my Web Application in VB.Net and Subsonic generates in C#.
Here is the process I followed:
1) I created a blank Web Application Project in Visual Studio
2) I configured the web.config to have the necessary parts, connection strings, etc.
3) I ran subcommander and it generated all the classes I needed into a folder called DAL.
4) I built the Web Application Project
5) I opened up a code behind, typed 'Imports' and I do not see the namespace that was generated.
I have even opened the actual Subsonic Source files and seen that there is a namespace statement for the generated namespace I configured. I tried briefly to move the subsonic files to a separate class library project, compile the .dll and use that in my project, but it still did not work.

View 2 RepliesI am running into a problem where my CRUD operations on an entity sourced from an SQL View is not calling the generated methods for said operations.I press "Delete" in a ListView on an item, connected to a LinqDataSource. It throws an error saying that it cannot perform the operation because it affects multiple base tables. That's fine, I understand that. What I don't understand is why this code won't run on insert/delete:[code]In debug, it won't break on the method, so it's not being called. I even did a test where I deleted the entity by attaching/DeleteOnSubmit and still no-go. Is this a bug or am I not handling the right method? I can handle a data source's OnDeleting event, cancel, etc. (which is my temporary fix) but I'd really like to catch ALL delete operations in a central place no matter how I delete the entity.
View 1 RepliesI'm quite comfortable with VB and have a very large project i need to do. I've come across SubSonic and it looks awesome. I am not clear if i can use it in VB. I've seen a a couple of posts that suggest they did but on the site it specifically shows C#.Can I use SubSonic with VB.NET?
View 1 RepliesI am trying to get subsonic to run work in a webservice I am not sure how to return the data. I only get the word Object in my results when It return anything instead of values. What am I missing?
<WebMethod(Description:="Method to retrieveCptCode subsonic List")> _
Public Function GetSubCptCodes() As CPTCodeCollection
Dim coll As CPTCodeCollection = New CPTCodeCollection()
Dim qry As Query = New Query(CPTCode.Schema)
coll.LoadAndCloseReader(qry.ExecuteReader())
Return coll
End Function
Followed Rob's webcast, did as he did, watched T4 generate the code, went to use the new namespace and oh. No namespace. I can see the namespace Test.Data in each of the generated .cs files, the tt files are included in the project as is subsonic.dll, there are no errors (I managed to get rid of a warning for the duplicate directives) but I just can't see the namespace. To test it out I am building a simple vb.net console application so wondering if there is a conflict there. Using v2.2 against the same db works fine.

I have an application I am converting over from vb6 to vb.net 2.0/3.5. Using Subsonic 2.2 and the vb.net Interop Toolkit 2005. Cannot seem to get the .net form using subsonic to work inside the interop environment.It keeps saying it cannot find the subsonic service provider in the app.config. But I know it is there. Has anyone used these two toolkits together successfully? Will subsonic even work inside the interop environment in that way?

View 2 RepliesI'm trying to use Subsonic 3.0.0.3 with an existing web site created in vb.net. I've added a reference to SubSonic.Core.dll and added the ActiveRecord tt/ttinclude files. I also added a contextmenu entry to run the t4 templates using instructions I found here.Whenever I try to run any of the tt files, I receive the following exception. Does this have something to do with me using a web site as opposed to a web application?

View 1 RepliesI am looking to make a database call based on user input. The line I am using is:general_read.CommandText = "SELECT * FROM general WHERE Business_Name = '" & business_name & "';"
business_name is dynamically loaded from:Protected Sub btnLoad_Click(sender As Object, e As System.EventArgs) Handles btnLoad.Click business_name = txtName.Text

The error that is being shown is: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.I'm assuming it has something to do with the variable not being set before the database call is made, but I'm not entirely sure.
I have the following snippet:

I've created a new ASP.NET Dynamic Data website and have used LINQ-to-SQL for the framework.
