I am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).

I have this
[Code]...
which is supposed to get all the data from my table and set it as the datasource of a DataGridView. You can see where I put in two msgbox's to view how many columns are in the DGV before and after the "update". The first count gives me 22, which is the correct number. After the .DataSource and .DataMember lines are ran, the count jumps to 41 and I have no clue why. All I want to do is clear a dataset, fill it with the new data and set it as the data source of a datagridview. It appears the info is being saved to the table correctly too.

I have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [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!

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"))

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 form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
