VS 2008 Delete A Row From Database With A Click Of A Button?
May 13, 2010
I am trying to delete a row from my database with a click of a button, my code is below but i keep getting this error "System.Data.OleDb.OleDbException was unhandled ErrorCode=-2147217900 Message="Syntax error in string in query expression 'Name=Sky ''."
Dim con As New OleDbConnection

"provider=Microsoft.JET.OLEDB.4.0; " & _
I am creating a project that accesses various databases and am stuck on deleting the database. I am using a Jet connection and I am able to display the database in a data grid view but I have two problems.The first is when I click on a certain square and I want to delete this row then how am I able to do this?The second is I want to delete the whole database with a click of a button.
Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:
I have ModalPopupExtenders that show associations that are NOT tied to a specific product. The associations that ARE tied to the product are shown in a tabcontainer with delete imagebuttons next to them. When I was testing earlier I noticed that the associations that I delete from the tabcontainer don't show up in the modal unless I click on the refresh button in my browser. Is there some code I could use that would make it so that when I click on the delete button, it will automatically refresh my Modal so that I won't have that extra step? [code]

Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.

2. The second thing is that I want to put text from my textbox into excel, but in specific row. I would like to do that with word file as well. I would like to put text form my textbox in specific table, or row, or line. I only know to put text into a file.
