VB Express 2008 Dataset Not Showing New Database Objects (views)
Mar 3, 2010
I am using VB Exopress 2008 and SQl Server Express 2008 in Windows Vista Home Premium. I have created a dataset after importing all tables and queries from MS Access to SQL Server. I have now added a view in SQL Server that I want to access and use in VB Express. However on clicking "Refresh" for the dataset the new view does not display in the available objects, only those I originally imported and opened with the original dataset. What, pleas am I doing wrong? How can I see this new View?

Using Visual Basic 2010 Express on Windows 7 whilst learning to program a database application using windows forms. I created a database (.mdf I think) with a tables e.g. patient details. Then created a form and dragged dataset and database adapter follwed by dragging database fields - this all worked perfectly well. I then created a table "tblSuburbs" with key suburbID, suburb, postcode fields. This also went well when creating a form to add, modify or delete suburbs. I modified my Patient table to include a link to the Suburb table - creating a relationship and saving both tables. Here comes my problem - Whilst the Database Explorer shows the "_SuburbID" field I added to my patient table, it does not show up in the DataSet even after I try and "refresh" every "refresh" button I can find. I need the DataSet to show the link field as I need the User to select which Suburb they in.

Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

I have designed an application for a company which has 5 client computers that read and write data to an sql2008 instance on a server.I would like to know the way to detect a change in a table whithout having to refill the table adapter.Let's say that all the client applications have a datagridview on the main form which binds to a table on the database lets say Members table (members binding source)Whenever a client makes a change to that table (lets say that it updates the Last name of a member) i would like the rest of the clients to detect that update and as a result ,update the specific row or cell in the datagridview.Is there some kind of event that is raised?

I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.

I have used list views for a project. I have used sum items on the items. The sub items are prices of products. I will need to use these sub items to come up with a total.Also, i have used to listviews, for a smoother look and feel. You click the product which then is removed from the list view and added to the second one. Would this also "move" the sub item across to the other list view?

Microsoft Visual Basic Express 2010 is Busy. I have to end up using Task Manager to end the process. I have been using VB Express for about a year and have never had this problem. i have tried to re-install VB 2010 express, no joy. I even built a Hello World app, still no joy. This is really stopping all my VB work.

for retriving database from .Mdb file i used following code
'decleared Name Space
Imports System.Data.OleDb
'Dicleared Variabls in Class Form1

how to move current record in datagrid, i mean when i press Next record button then datagrid's data (table) also should move to next record or when i click any record in datagrid, then the current record of dataset also should move to clicked record of datagrid, so that i also may see datagrid's clicked record in textboxes in short i want to use default feature of vb6's ado control, when we bind datagrid with ado control, it worked autometically, both data grid and adodc wer connected each other at a time, so that moving next record also apears in datagrid.

I want to create and populate populste several databases on my server MySQL. I pretty much know how to handle the data and queries once I have a connection, it is connecting that I don't know how to do. I have read all the help file I can find till I am sick of reading about "Northwind" which doesn't help me a t all. What I need are the three or four lines that establish a connection to MySQL at [URL] I need to be able to establish this connection transparent to the user who needs only to put thier user name and password for the site into a configuration file. Then I need to be able to create a database and give the user access with thier username and password. I know how to create the database but not how to set the username, password and permission.

I am using VB 2008 express and SQL Server 2008 express on a test basis and I used to connect VB express to a SQL database (created in SQL Server 2008 Express management studio) file and it work perfectly until my hard drive packed up and I had to get a new one, so I had to reinstall both of these again and copied my old databases from a backup I had. Now when I try to connect to the database file it cannot connect. Network related error or the instance name is incorrect. When I look at the advanced options in the connect dialog it shows my instance as .SQLExpress and my correct instance name is .SQL2008Express. I clicked OK on the connect dialog and manually changed my connection string to the correct instance and that worked but whenever I run the application in debug mode it give me the same error as above.

I added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.

Would like to know if it is possible to access a Primavera 6.2.1 database (.mdf) from VB 2008 Express. Would like to take advantage of the existing database, if possible.
It is easy enough to export to Excel and then develop an Access database, but I would like to avoid those steps.

With the following code, I'd expect to get the array elements back that I put in. Instead, the last array element, is output three times.e workaround would be to dimension the array explicitly to hold four strings, but I used this contruct all over my VBA code and I'd rather know why it doesn't do what I expect.
Sub test_d()
Dim youvegotitems(100) As Object
Dim v(4) As String

I sometimes come across patterns or common practices that I do not agree with. I have a clear opinon of what is considered "good design", which is mainly based on my understanding of abstraction and creating layers.IMO, the core of an application is it's object model. It's a hierarchic model where one object references other objects or lists of them. That's a memory-internal model. For example, a house object references a list of rooms referencing lists of furniture.An object is identified by it's reference. There are no IDs or PKs in that layer.Saving/Loading data is an additional feature. Sure, no application will do without, but it's based on top of the core of the application. I could write an application that works very well without loading/saving, and for version 2 I will think about whether to save data to a database or an XML file. Merely this fact proves that a database layer is not the lowest. I've never agreed with that three-tier model - even if you call me unteachable.
In addition to all application objects, there are Datasets - and that's my problem now. They can be considered as a copy of what is already present in the application's object model. Its from a different, table-oriented view. As both structures exist in parallel, there's the need to synchronize the DataSet with the (rest of the) application's objects.That's the task that I am always struggling with, and I ask how you handle it. I know this is a major design question but, fortunatelly, I could quite get around this problem so far.The only solution I can imagine is maintaining additional relation lists. For example, whenever the property of a room object changes, that change must be reflected in the associated DataRow in the DataSet. For this purpose, I need a look-up table that tells me the PK of the given room in the database. It requires a lot of additional efforst to do all the synchronization.Again, the house or room object itself does not have a PK and it won't get one because on that layer, it doesn't even know that a database exists.

Microsoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.

1.Establishing a connection to a database(preferably one that is inherit within the project and can travel with it)
2. Setting the correct references to the database ( I tried connecting via JET with windows 7 and I get an error that I cannot use JET)
3. Query the database (Access) with SQL, and return those results to a recordset.
4. Loop through the recordset.
5. close the database connection
6. Open recordset and write data to table.
