Datagridview Selected Row Delete When No Pkey Is Set

Feb 9, 2011

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.

Delete A Row In DataGridView AND Database Deletes The Next Row After Last Selected Row

May 15, 2011

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!
Private Sub zDelete()
If MessageBox.Show("Do you really want to delete the selected rows?", "Delete", MessageBoxButtons.YesNo) = DialogResult.Yes Then

Delete The Selected Name From The List?

Nov 6, 2010

I'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.
