why "import namespace=" ..." if not necessary?

[Chris]

Hi,

1) In file test.aspx, i put:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test.aspx.vb"
Inherits="test" %>
<%@ import namespace="System.Data"%>
<%@ import namespace="System.Data.OleDb"%>
....

In file test.aspx.vb, i put:
....
Dim oConnection As System.Data.OleDb.OleDbConnection
....
No problem.It works.
----------------------------
2) But if i put in test.aspx.vb:
....
Dim oConnection As OleDbConnection
....
I get the error: "type OleDbConnection is not defined"
---------------------------
3) if i remove the import lines in test.aspx: and put this in test.aspx.vb:
Dim oConnection As System.Data.OleDb.OleDbConnection
.....

it works too.

So my question: why putting the import namespaces in test.aspx, because in
any way, I have to use "Dim oConnection As
System.Data.OleDb.OleDbConnection" instead of "Dim oConnection As
OleDbConnection" ?

Thanks
Chris









Why then the import in test.aspx?

Hi Chris,

If you want to write the script in the same aspx page then the Import
statement is required other wise it's not required.

Hope this is clear.

Hi Balu,

Thanks for replying, but i still don't understand.

In my first file (test.aspx)
----------------------------
<%@ import namespace="System.Data"%>
<%@ import namespace="System.Data.OleDb"%>

In my second file (test.aspx.vb)
--------------------------------
Dim oConnection As OleDbConnection


This doesn't work.

I have to put:
Dim oConnection As System.Data.OleDb.OleDbConnection
But then, if i remove the import lines from test.aspx, it still works.

So why putting those imports lines?

Import the namespaces in the file where you use them. If you want to use
the namespace in the vb file, import them there:

Imports System.Data
Imports System.Data.OleDb
