System.FormatException

Hi Guys,

When I trying to execute this code,

insGrupo = Nothing
insGrupo = New Grupo(Short.Parse(0), TxtGrCoCodi.Text)

occurs the following error

System.FormatException: Sequence of entrance was not in a incorrect format.

Somebody knows what it can be this error?

System.IndexOutOfRangeException: There is no row at position 0

I'm getting a frustrating error that I can't seem to figure out with an update button. However, when I try to execute the Submit_Click sub I get the error that is the subject of this post. Can you see anything wrong with my code? The GetRecord sub work great on page_load to get the record in the first place, but in re-calling it it's not working.

Please help if you can, thanks!

Oh, E_ID refers to a context item (Dim E_ID as String = Context.Items("EmailID"))

Sub Submit_Click(Sender As Object, E As EventArgs)
GetRecord(E_ID)
Row = IndividualDS.Tables("Individual").Rows(0)
Row.Item("F_name") = FirstNameText.Text
Adapter.Update(IndividualDS, "Individual")
End Sub
Sub GetRecord(E_ID As String)
SelectStatement = "Select * From Individual Where Email='" & _
E_ID & "'"
ConnectString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & server.mappath("policy_dir.mdb")
Connect.ConnectionString = ConnectString
Adapter.SelectCommand = _
New OleDbCommand(SelectStatement, Connect)
Adapter.SelectCommand.Connection.Open
IndividualCB = New OleDBCommandBuilder(Adapter)
Adapter.Fill(IndividualDS, "Individual")
Adapter.SelectCommand.Connection.Close
End Sub

You may find some helphere.
Thank you, that did help.

I am closer... I am now getting an error that says "operation must use an updateable query" what should I check for to correct this?
Check the search result in Google.
Thanks, I think i got it fixed

System.InvalidOperationException: Connection must be valid and open

Hi.
I am using this function tu execute updates to a MySql database from a sql
string, but I am getting a System.InvalidOperationException: Connection
must be valid and open.
Database queries work fine, but I cant update the source. Am I missing
something?
Thanks, Alejandro.
public static bool updateSource(string sql)
{
MySqlConnection conn = new MySqlConnection(myConnectionString);
MySqlCommand command = new MySqlCommand(sql,conn);
command.CommandType = CommandType.Text;
try
{
command.ExecuteNonQuery();
return true;
}
catch (Exception)
{return false;}
finally
{
conn.Close();
}Hello Alejandro Penate-Diaz,
Exactly what the error message says... You need to have a valid *and* open
connection.
Try adding conn.Open() before the command.ExecuteNonQuery() method.

Heyy, thanks!! Problem was that I was like copy-paste and didn't realize
that DataAdapter.Fill actualy does that for me but in this case I have to do
it by myself. ;-)
Thanks a lot!
Alejandro.
