why can't update database

this code is work (can update my database)

VB Code:

Dim dt = DataSet11.Tables("Customer")
        dt.Rows(myMgr.Position)("CustomerPersonalID") = [COLOR=Red]1234567890[/COLOR]
 
        OleDbDataAdapter1.Update(DataSet11, "Customer")
        DataSet11.AcceptChanges()

but this code can't update my database

VB Code:

Dim dt = DataSet11.Tables("Customer")
        dt.Rows(myMgr.Position)("CustomerPersonalID") = [COLOR=Red]txtCustomerPersonalID.Text[/COLOR]
 
        OleDbDataAdapter1.Update(DataSet11, "Customer")
        DataSet11.AcceptChanges()

was i do wrong ?
thanks!

1234567890 is a number. txtCustomerPersonalID.Text is a string. If the second represents a number then it may be implicitly converted, although I wouldn't count on it. If it doesn't represent a number then it definitely won't work.

how to resloved this problem ?
i'm .net newbie

Validate the contents of the TextBox and convert it to a number.

If you're using VB 2005 look up the Integer.TryParse method. If it's an earlier version look up the Double.TryParse method

sometime my data can use char ex: A0137521
is anyway to dt.Rows(myMgr.Position)("CustomerPersonalID") = String

thanks!
