Database Permission

[Julie Barnet]

Could someone please tell me how I can trap permission errors in
vb.net on a stored procedure:
ie. Execute permission denied on object 'sel_mytable', database
'mydatabase', owner 'dbo'

I would like to print a message like
response.write("You don't have permission to select on this table") as
opposed to the cryptic message I am receiving.

Thanks in advance

You can trap a SqlException and translate the error as desired in your code.
VB.Net WinForm example:

Try
sqlCommand.ExecuteReader()
Catch ex As SqlException
Dim PermissionError As Boolean = False
For Each sqlError As SqlError In ex.Errors
If sqlError.Number = 229 Then
PermissionError = True
Exit For
End If
Next sqlError
If PermissionError = True Then
MessageBox.Show("You don't have permission to select on this
table")
Else
MessageBox.Show("Unexpected error: " & ex.ToString())
End If
End Try

Hope this helps.

I am databinding a datagrid. I tried that and it still doesn't seem
to work. I will paste my code...

Is there something I'm missing?

Public Function BindGrid(ProcName as String, myDataGrid as
DataGrid, cmd as SqlCommand, con as SqlConnection) as Integer
Dim ds As DataSet
Dim da As new SqlDataAdapter()

Try

cmd.CommandText = ProcName
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = con

da.Selectcommand = cmd

ds = new DataSet()
da.Fill(ds, "MyTable")

myDataGrid.DataSource=ds.Tables("MyTable").Default View
myDataGrid.DataBind()
return ds.Tables("MyTable").Rows.Count
catch exp as SqlException
HttpContext.Current.Response.Write("Exception3")

End Try
End Function

I ran your code and got the "Exception3" message. What symptoms are you
getting?
