Using Table Adapters To Insert A New Row Doesn't Do Anything?
Apr 1, 2011
I'm using visual studio 2010 to build my application and SQL server 2005 to store the data. I created a table adapter, dataset and binded the controls to my already made formThing is, i'm trying to insert a new record into the database and it won't work! I can fill the form with a record from the database and update it so i know its definitely connected correctly. Everytime I try to insert a new record whether its through a table adapter or manually, I just can't seem to get it to automatically save to the database.Ive put this under the save button
Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click
Dim CustomerRow As accountingdbDataSet.CustomerRow

I recently created a test VB.NET 2008 project with an Access database and it seems to work okay. It uses a dataset and table adapters. I'm aware that some people don't like table adapters. I'm willing to learn another way if it's better. Should I do this or continue using table adapters?

How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.

You can iterate the controls collection and me.components.components to find certain objects, but nowhere can I find where a form keeps a collection of its early-bound table adapters. When you add them in at design time and bind them to a control, it shows them on the design window, and it creates them in the design.vb file, and they're available as a property of your form object... but I can't find a way to browse through them and pick one in code, like you can with the control collection (I.E. me.controls.Item("controlname")).[code]...

i am working on a project that stores records from a windows form to an access datbase.But i am having problems with the update statement.I have a form with the fields bound to datatable called LeedsHubInfo .Dataset called LeedHubInfoDataSet1.
Private Sub cmd_save_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles cmd_save.Click
' Create a new row.
Dim newJobRow As leedHubInfoDataSet1.LeedsHubInfoRow
newJobRow = Me.LeedHubInfoDataSet1.LeedsHubInfo.NewLeedsHubInfoRow()

On the update line i get an exception thrown up "A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll" I thought inserting a record into a database would be easy but i seem to be naking a right pigs ear of it?

Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).
So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.

I would like to know if it is possible for a Table Adapter to reference a query as opposed to a table. Currently my Table Adapter references a table in my SQL database, but I wanted to know if it was possible to have it reference a query, which selects a table from another database?

In a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".

I have a project that I used the 'Connect to Database' tool to set all the bindings and table adapters, etc. Currently the database is housed in the same directory as the exe. I was asked if I could have the database location be a dynamic value. My question is when you set up a project to work with a database using the 'Connect to Database' tool, how can you change its location?
I found this setting:
ASRDBConnectionString
But its read only.
Within that setting is text that says: DataDirectory
So thought that might be a variable to change somewhere....but can't find it.

I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

I have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

I have a csv file that I need to import into a sql table, this portion is working correctly. The code grabs the data, displays it in a datagridview and then imports it into the sql table. What I need to do is add an additional field that will automatically number itself by the amount of rows inserted at that perticaular moment. Let me explain a little clearer. The data I grab from the csv file is a day snapshot broken down to the hour. So lets use todays date 6/28/2010 will be broken down in the csv file like this:
Date
Time

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.

So I have a program that I am converting to .NET FW 3.5 and I am getting the titled exception on the following line:If IsNothing(dsTopPI.Rows.Find(profile.Item("GEMSID"))) Then Continue For
which is in a for each loop. The thing is, I have set the primary key and when I put in the following code:Dim columns() = DSTop30Profiles1.DTtop30profiles.PrimaryKey Console.WriteLine("Column count: " & columns.Length.ToString)For a = 0 To columns.GetUpperBound(0)Console.WriteLine(columns(a).ColumnName & " - " & columns(a).DataType.ToString)Next
I get this in the output:Column count: 1 GEMSID - System.Int32
That would seem to indicate that there is in fact a primary key, right?

What is going on with my code. To .NET and handling SQL connections. I am trying to catch an error where lets say someone puts in something that violates the rules of the field (i.e. they put data in a field that doesn't matched what is on the other table.) Please find teh code I ahve put on the save button to try to catch the error. Instead of popping a message box up the program just closes itself.

It seems like when there is only one row at the data grid view with a data source pointing to a data table, it's row state for the data table doesn't change when editing. It remained "unchanged" reguardless to how many columns I had entered. However,after editing, when you click on a different row or click on any of the column headers to change their sorting, the row's state from the data table then gets changed to "modified". I'm not sure why the data table's row states gets changed only when you do those things instead of finishing editing itself. Couldn't the data grid view be able to change the data table's row states when you finished editing a cell?
