POP3 Service

Hi.
I need to create an application (service) that will be active in the
background all the time and receive mail. I can't use Microsoft Exchange
Server, I have to make my own. Only problem is that I have no idea how to do
it. Does someone know where could I find some examples or how to do it.
Thanks a lot.PhatCat:
POP3 is a protocol to retrieve mail messages from a mail server. Did
you want your service to poll a mailbox and pull down new messages? Or
did you want your service to listen on a port and actually take emails
via SMTP? (http://www.faqs.org/rfcs/rfc821.html)

populate ddl from two tables

Hello,
I have two Tables: Table1: GroupID1, GroupName1 and Table2:GroupID2,
GroupName2.
I have only one dropdown list (DropDownList1) in my application and through
a stored procedure I want to populate my DropDownList1 from GroupName1 and
GroupName2. How should I write my query?
Thanks,
Jim.You'll probably want to use a union.
select companyname from suppliers union select shipcity from orders
try this on Northwind, it'll return the companynames and shipcity in one
long list.

Populating a Dataset

I've created a vb windows application and written the following function within a class (class1). I dragged a dataset onto my form and renamed it datBookInfo but when I run the code I don't get anything in the form.

Please tell me what I'm doing wrong.

 Public Overloads Function GetBookInfo() As DataSet
 Dim oPubConnection As SqlConnection
 Dim SConnString As String
 Dim osqlCommPubs As SqlCommand
 Dim osqlCommTitles As SqlCommand
 Dim oDataAdapterPubs As SqlDataAdapter
 Dim oDataAdapterTitles As SqlDataAdapter
 Try
 SConnString = "Data Source=(local);Initial Catalog=Pubs;" & _
 "User ID=sa;Password=;"
 oPubConnection = New SqlConnection(SConnString)
 oPubConnection.Open()
 'Create command to retrieve pub info
 osqlCommPubs = New SqlCommand
 osqlCommPubs.Connection = oPubConnection
 osqlCommPubs.CommandText = "Select Pub_ID, Pub_Name from Publishers"
 'Create Data Adapter for pub info
 oDataAdapterPubs = New SqlDataAdapter
 oDataAdapterPubs.SelectCommand = osqlCommPubs
 'Create command to retrieve title info
 osqlCommTitles = New SqlCommand
 osqlCommTitles.Connection = oPubConnection
 osqlCommPubs.CommandText = "select Pub_ID, title, price, ytd_sales from titles"
 'Create data adapter for title info
 oDataAdapterTitles = New SqlDataAdapter
 oDataAdapterTitles.SelectCommand = osqlCommTitles
 'Create and fill a data set
 Dim datBookInfo As DataSet = New DataSet
 oDataAdapterPubs.Fill(datBookInfo, "Publishers")
 oDataAdapterTitles.Fill(datBookInfo, "Titles")
 Return datBookInfo
 Catch ex As Exception
 Finally
 oPubConnection.Close()
 End Try
 End Function

check that if the dataset is populated when there is no PostBack.

If(!Page.IsPostBack)
{
 LoadData();
}

Hmm, dont see anything obvious...How are you doing your bind of the dataset to the grid?

Also, since this is a windows project and not a web project (assuming your "I've created a vb windows application" is correct) there will NOT be a page.isPostBack...

Thanks,
MajorCats
