Deleting an item from a Grid (vb 4.0, 32bits)
I created a grid control on my form. The grid filled from a database(Access). I created a routine where I can add an item to my grid without any problems, but I can't seem to figure out how to delete that same item. I declared the variable Table as Recordset and put in the following line of code:
Dim Table as Recordset
Set Table = dbTFH.OpenRecordset("Truck
Table.Index = "ID"
Table.Seek "=", grdtrucks.Text
When I use the 'Table.Delete' method I continually get an error message saying, "Run-Time error '3021', No current Record" and it points to my 'Table.Delete'.
Do you have any ideas on the matter?

Try:
Table.Bookmark = Table.LastModified
Table.Delete

The problem is your seek statment did not find a record, therefore your record pointer is located on the EOF marker.
You need to check to see if your seek statement found a record before you try and delete it.
do so by checking the nomatch property of your recordset, like so:
IF Not TABLE.nomatch then
Delete your record here
else
it didn't find a record.
endif
or you can just check to see if the table is on the EOF by:
if Table.eof then, it didn't find a record.
Thanks Brad.

My seek statement did not find a record. I tried Table.Movefirst before the seek statement but that didn't work. So now the problem is related to the seek statement.
I tried
Table.Bookmark = Table.LastModified
Table.Delete
but that didn't work. It still gives me the same "No current Record" error message. Just to verify I also had the following code before the delete:
grdtrucks.Col = 0
Table.MoveFirst
Table.Index = "ID"
Table.Seek "=", grdtrucks.Text
Any suggestions?

first off..... I am assuming that ID is a long integer, and Text as string (that I know) so you need this, minimum
table.seek "=", clng(grdTrucks.Text)
if table.nomatch then
msgbox "You did not select a record"
else
table.delete
table.movefirst
end if
Secondly... which grid are you using? The grid could do it for you. If you are using DBGrid that comes with VB, when you move to a record, it moves the pointer for you.
I would recommend making sure grdTrucks.Text is an ID
table.seek "=", clng(grdTrucks.Text)
if table.nomatch then
msgbox "You did not select a record"
else
table.delete
table.movefirst
end if

I am NOT using DBGrid. I am using Grid. Should I switch and is the coding more or less the same?
"ID" is part of a table in the database. Each Truck in the database is given a unique ID number. ID is never declared as long. There is no reason for that. I am trying to perform a search on a record in a table and then delete the record I searched for. I have tried all suggestions but nothing has helped. Is it possible that my problem is elsewhere in the project? Here is my code exactly as I have it(and it doesn't work):
Dim Table As Recordset
Set Table = dbTFH.OpenRecordset("Truck
grdtrucks.Col = 0
Table.MoveFirst
Table.Index = "ID"
Table.Seek "=", (grdtrucks.Text)
If Table.NoMatch Then
MsgBox "You did not select a record"
Else
Table.Delete
Table.MoveFirst
End If
