An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I used the DataSet Designer to create FTWDataSet which holds the AlarmText table from a SQLExpress database.This far my form contains ONLY Datagridview1.The code below successfully shows the contents of the AlarmText table plus the one added checkbox column (which I will populate with display-only data, and is not an issue here).
Dim ta As New FTWDataSetTableAdapters.AlarmTextTableAdapter
Dim dt As New FTWDataSet.AlarmTextDataTable
ta.Fill(dt)[code]....
What else do I need to do to use the DataGridView to edit and save values in the AlarmText table?
I have followin codes

View 1 RepliesI have a table in Access with two key fields (let's call them Item and Cust). These key fields *combined* are the primary key. So each record must have a unique Item and User combination. It can have a duplicate Item with other records, and a duplicate Cust with other records, but not a duplicate of both. Because my "primary key" is a combination of two fields, I can't make a primary key on the table in Access (it only supports one field as a primary key).
I have another table in SQLServer which also has Item and Cust, but in addition, is has several descriptive fields that give more details about the Item and Cust. I'm trying to use ADO.NET to bring in that SQL Server table and UPDATE some matching fields in Access with the descriptive fields. [Code]

I have a dataset with numerous tables.I have changed the column type of a couple of columns in the source DB form smallint to int.No I need to update the datasets (and eventually the code) to the appropriate datatype.Rather than hunt around the dataset and find all the places where these columns are referenced is there a way to direct the dataset to go back to the DB, reread the queries and update the datatypes.I know I can either change the field or one by one go to each table and force it reread the query but I want the dataset to do it in mass.
View 3 RepliesI was wondering if the following is possible. In a particular operation I want to create a dataset, bulk copy it to another SQL Server, then update a flag column in the copied rows.I'll have a system that will be regularly inserting new rows of data, then at regular intervals want to copy that data to another SQL Server. Once the rows have copied I need to change a flag column so that they won't get copied again.Whilst this is going on there is a strong possibility new rows of data will be being inserted into the source table. These new rows will be copied at another interval.
View 3 RepliesI have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** "
Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1"
Dim da1 As New SqlDataAdapter(strSql1, strConn)

I have been given a task to create a new billing system for my company and I have been trying to get the customers from one Access 2000 database into the SQL Server 2005 table
Public Sub IPCustomers()
Dim rtn As Integer
Dim OLEDBConn1 As New
[Code].....
The problem lies in the strSQL where you see dbo_Libraries.LibDescription.Value and dbo_Libraries.LibID.Value.
Before, I merely put single quotes around the fields from the from the Access Table and it inserted exactly the code itself, dbo_Libraries.LibDescription.Value and dbo_Libraries.LibID.Value , and only 1 record. There are over 300 records in the table.
When I put double quotes around both, separating them out from the string I get the error "Arguments Not Set."
Ok where am I messing up here, I had this working to a local SQL 2005 instance. However I am unable to get this to work to a remote SQL instance. Why?

View 3 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
