datagrid help

[Altman]

I am quite new to VB.net and I am struggling with the datagrid. I want to
let the user modify data in the grid and then click the save button and this
will update the database. I guess I am having trouble understanding the
update command and the parameters. The data is coming from an SQL query on
2 tables, but I will only need to update one of them. I got the grid to
show the data but I can't get it to update. This is my SQL statement

Private Const SELECT_STRING = "SELECT equipment.eqp_d escription, as
Equipment,io_ma ster.io_number, io_master.io_pa nel_id,equipmen t.eqp_id,
io_master.equip ment_io_functio n FROM io_master Left outer join equipment on
io_master.eqp_i d = equipment.eqp_i d order by io_master.io_nu mber"

My update needs to be this:

UPDATE io_master SET equipment_io_fu nction = ? WHERE io_panel_id = ?

I'm guessing that this is right:

Dim cupdate As OdbcCommand = New OdbcCommand("UP DATE io_master SET
equipment_io_fu nction = ? WHERE io_panel_id = ?", OdbcConnection)

and then I set the odbcAdapter.upd atecommand = cUpdate

My problem is I don't quite understand the cUpdate.Paramet ers.add

Can someone help me with what I should put in there?

Altman,

First question Windowforms or Webforms and than why are you using ODBC
instead of OleDb. ODBC will give you much more work.

it is for a window forms and we are using ODBC because it is already set up
for Crystal Reports. This means the application will not have to find out
from the user where the DB is located. Otherwise I would have used OLEDB.

Altman,

The ODBC is not always save however I saw that there is as well an
commandbuilder for ODBC which maybe makes your live as easy as it is with
OleDb.

Althouhg it has with OleDb as well bugs, or maybe I am wrong because while I
write this I remember me that the one who always tells that the
commandbuilder has bugs likes very much ODBC.

However maybe it will make your live much easier
