How To Setup 'connector' To An Existing Database
Jun 19, 2010
I'd followed Beth's video which nicely explains how to setup a "connector" to an existing database. Also, I've updated a method to retrieve information from one of the tables.Now, I need to retrieve information from the table, but I don't succeed to find the "method" to do so (I don't get to the situation that "Fill" or "GetData" are recognized methods). Could anyone send me references through which I could easily understand. how this needs to be done?

Dim rp As New ReportDocument
Dim myData As New MyDataSet
Dim dt As New MyDataSet.UserDataTable[code]....
When setting the datasource It comes up with an error:Unknown Database Connector Error.....Error in File C:DOCUME~1A_RAHN~1LOCALS~1Temp1Report {832105B2-2E31-4018-9761-77581CC86142}.rpt:Unknown Database Connector Error
I created that report by Crystal Reports 2008 Stand-alone IDE rather than generating it in VS2010 IDE and it is binded to that dataset dutring the crystal report wizard.

So, what I'm trying to do is to connect to a remote database using the MySQL connector. Dim c As New MySqlConnection c.ConnectionString = "Server=" & URL & ";Database=" & "" & ";Uid=root" & ";password =" & "" c.Open()I know the connection string is correct. I can access the phpMyAdmin through a web-browser just fine. For some reason however trying to open the connection throws an exception 'Unable to connect to any of the specified MySQL hosts'. I tried disabling the VS debugging process, as I thought maybe it's blocking my MySQL access for some reason, but no.

I'm creating another database searcher, only this one is a little better user friendly than the one I made with a datagridview. I'm using the "details" of my dataset(CustomersDataSet) and trying to add a record into an existing database. I'm using this code
Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet)
which worked for me when using the datagridview, but for some reason it won't work now. Even when I check for my test "add a customer" in the access database itself, it isn't added.

I need to add a column to an existing table in my database. I am having trouble adding a column to my database. I physically go into Microsoft Access and add the column, my problem comes up when Visual Studio does not recognize the table. Basically, I think I'm doing something wrong.

I would like to make a copy of an existing database in microsoft SQL Server 2005 in code, if that is possible. I'll need to make a copy of the original one, and change the name to some other name choice. All tables, stored procedures and such will be exactly the same.

how to update records on an existing access database using vb.net with just a textbox and a command button and how a specific record of a field can show up in a label or a textbox
i connected vb.net to my access database by just clicking on "add new data source">>"new connection">>"microsoft access database file" and just continue..tested connection and done.
you can see in the screenshot of my form, by default the left side textboxes are disabled but they're enabled if the user checks the checkboxes and disabled again if unchecked.
assuming that the textbox is already enabled and i want to enter a value in the Brewed Coffee area of the form...for example 5. when i click on my Submit button the value of that particular record in the database will be updated, so in my table the value of the quantity field in Brewed Coffee will be 5.
another thing is that how can i see a particular value on a label or textbox from my database like on the Prices area. in my database if a product's price is 80 then it should show a 80 in the label. the values of the prices from the screesnshot of the form are not the ones on the database xD i just typed them in.

I'm having a problem with the error in verifying the usernames that are already existing in the record/database.
When you inputted a username that already existing it will throw an exception, and when you change the username, it still throws the exception.

I trained myself to program beginning in 1980 with the Basic language for Radio Shack's TRS-80 Model III.Later learned to program macros in Lotus 1-2-3, then taught myself DBase, then started Visual Basic.I've trained myself on Visual Basic up to VB 6.0.Now, as I understand it, Windows 7 and beyond will not support using VB 6.0. I have programmed many pieces of software we use in our offices.My software is Access Database intensive. I put the database on the server and we can connect from our various computers to the databases and work on the data as necessary.I've never gotten into Server/Client types of organization because I don't understand the server model and how to do that...For the sample databases one needs a server application running and I don't have one (Our server only has a standard operating system on it).
Now I was looking at Visual Basic 2010 and am totally lost.In VB 6.0 samples, I could put a break point (debug) and stop the program and examine what it is doing.now I don't even know where to put a break point..When I put one in the samples, the sample application loads and does not hit the break point...Is there anywhere I can learn how to move up to Visual Basic 2010?I don't want to have to quit my job and go back to school but it seems soooo different from VB 6.0.Just trying to figure out 'datasets' is a chore and to see how they work in the samples, I have to set up some form of database somewhere and it does not show me how.

I have written many programs and never really needed a database before. Just never came up. I am a self learned programmer. I have experience in using php and database on websites etc. I am currently writing a program in VB 2010 and need some assistance in using a database.simplest way to setup and use a database in VB. I would believe that it's better then saving "clients/data" to a file. . The software is being created only to be used on one computer and not over a network etc.

I am using VB 2008 Express. When I publish my project, all files show up properly in the publish directory. When I go to setup.exe it installs with no errors. When I go to launch the program it says it is missing the database. Sure enough the database that is suppose to go along with the install does not get copied over. If I manually copy the file to the install directory and remove the .deploy from the name the program works like it should.[code]...

I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

I am using Microsoft Visual Basic 2010 Express. I have a WPF-based project. I have a successful connection to a database in Database Explorer, and a working existing Data Source in Data Sources.
I created a datatable from the datasource using this code:
Dim roster_table As New DataTable("AGENT_ROSTER")
I can manipulate this datatable just fine, but I cannot figure out how to save its data to my database (agentroster.sdf) since the connection is on a global level, and isn't declared in this particular window.
How do I update this database from the datatable on this window?By the way, I tried creating a connection on this window's code, using the exact same connection string as the successful globally-connected database, yet it said that it couldn't connect.

I have a purely XML database. It's stored as XML, there is no other database file. I did this by first creating a dataset in VB, then adding tables and relationships. I load the database by calling DataSet.ReadXml(FilePath), and save the database by calling DataSet.WriteXml(FilePath).
Now I need to make schema changes, but need to preserve existing data. How might I go about doing this? As soon as I load the database I loose all data if I change the schema in the dataset designer.
I have searched for changing database schema, but everything I find deals with real databases, not XML only ones, and the info doesn't apply because they are using db connections and then running sql against it and AFAIK XML databases have no way to "connect".
