[2003] Update Unable To Find TableMapping['Table'] Or DataTable 'Table'?
Sep 26, 2008
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.
dr = dbDset.Tables(0).Rows(CurIndex)
dr.Delete()
dbAdp.Update(dbDset.Tables("addresses"))

I have a bound datagrid which I fill from various search options that are available to the end user.Currently I have one of the columns (status) set as a DataGridViewComboBoxColumn with a collection of two items. 'Open' and 'Closed'When the I select for example 'Closed' and hit the 'Update' button an exception is passed with the caption'Update unable to find TableMapping['Tracker'] or DataTable 'Tracker''I have been looking at hope the mapping works for the last 3 hours but getting nowhere fast and I really need to get this project completed by the end of the week.The bound controls are:
Binding Source = BS
Data Member = Tracker
Data Source = TrackerDataSet

I have the following code:
Imports System.Data.SqlClient Public Class Exceptions Private Sub Exceptions_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
that it looks as if my data adapter is trying to update the Scratchpad3, but what I need it to update is ExceptionsEdit. My question is, how do I get my data to post to the ExceptionsEdit table in my database rather than trying to post back to the Scratchpad3?

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 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 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!

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.

I need to Update Access Database Table with Data from a Different Table. Not all the rows of original Table to be Updated will be affected. How do you loop through the 2 Tables to do the required Update.
The Table to be updated is called "RecordList" and Table with new Data is called "RecListReport".Every attempt I've made won't work. I tried to Use 2 Datagridviews but couldn't get it to work right.

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...
