So i'm steadily learning more about table adapters and SQL commands. One of the latest things i'm trying to figure out is how to correctly delete a datagridview row and have it update the database when no Pkey is set on the database. I'm sure i'm missing something simple, all i've managed to do so far is delete everything Obviously when no pkey is set the table adapter wizard doesn't generate the delete statement.

I try to do a very simple job which is: Delete a row in dgv AND database! But now after three days I'm running out of steam
The problem is: I select on or more rows in dgv and push the del button. The sub zDelete starts working and at the end the selected row is gone and the row after my selection is gone too!?!? The deletion of the selected row was well done in dgv and database. But why is the next row in dgv only also disappeared??? After a restart of the form the missing row is back up again. And when I try to delete the last row it trows an exception error: System.IndexOutOfRangeException was unhandled
The code fragment is this:
'Delete all selected rows in dgv AND database!

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

I am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.
So Table looks like this:
Name, BadgeNum
I need to be able to find instances like this:
John, 10
John, 10
and then delete just one iteration of John, 10.
Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....
I have a main form (Form 1) with a menu strip and navigation bar. I use the main form to launch other forms (Form 2) as children of the main form.
All of the children forms contain SQL data sets /grids. I would like (if possible) to use the save button on the main form, to save data changes of the children form to the SQL database.
I have a problem with the GridView: after I selected the value that I should void, it should be deleted on the GridView. I use this code dtable.Rows.RemoveAt(i) but it's not working.

View 11 RepliesI've been working on a program lately. On the form load it loads a list box with a list of names from a .txt file. It's a sign in form, so when people click their name then the button it will write to a .txt file their arrival time, and the folder is their name. I can make it do it one at a time, but that's so inconvenient. I have the list box set so it accepts multiple selections, but I need to make it write the time for everyone.
how to delete the selected name from the list that would be extremely helpful, that way the person isn't signed in multiple times.
I have a combobox. The data that it binds to should be:
AcctID AcctName
10 Main
11 Old

Once again I have hit a brick wall here. I have a combobox in which the user types the server name and then clicks on button 'CONNECT' to populate the next combobox which contains all the databases in that
server. Then after the user selects a database, I have another button that he/she click and I want to retrieve file groups from a specific table. At this point when he/she clicks on that button I get an error: "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
