sending email via Exchange

You have to create the controls, like I preseume you already did, and add them to the Form's Controls collection. After that, you have to write your event handlers using Sub's with the same signature as the event you want to handle (see the documentation for each event), then manually wire up the events using AddHandler[^]. Don't forget to disconnect the events handlers using RemoveHandler if you need to destroy the controls later.

I have Exchange setup on a server and I am trying to write an ASP.NET application that saves some form data to a database, and then sends a notification email to a 3rd party.

I used the code, pretty much verbatim from here Support @ Microsoft[^]

I added the Office11 COM object as a reference; however, on the line oApp = New Outlook.Application() I get a weird error saying that the

ASP.NET is not authorized to access the requested resource

Any ideas on how to resolve this?

Image combobox help

Hi.

I am new to this site. I found an example of an image combobox by Alon Ronen. The code is as follows:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load

Dim items(Me.ImageList1.Images.Count - 1) As String

For i As Int32 = 0 To Me.ImageList1.Images.Count - 1
items(i) = "Item " & i.ToString
Next

Me.ComboBox1.Items.AddRange(items)
Me.ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
Me.ComboBox1.DrawMode = DrawMode.OwnerDrawVariable
Me.ComboBox1.ItemHeight = Me.ImageList1.ImageSize.Height
Me.ComboBox1.Width = Me.ImageList1.ImageSize.Width + 200
Me.ComboBox1.MaxDropDownItems = Me.ImageList1.Images.Count
End Sub

Private Sub ComboBox1_DrawItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.DrawItemEventArgs) _
Handles ComboBox1.DrawItem

If e.Index <> -1 Then
e.Graphics.DrawImage(Me.ImageList1.Images(e.Index), _
e.Bounds.Left, e.Bounds.Top)
End If
End Sub

Private Sub ComboBox1_MeasureItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.MeasureItemEventArgs) _
Handles ComboBox1.MeasureItem

e.ItemHeight = Me.ImageList1.ImageSize.Height
e.ItemWidth = Me.ImageList1.ImageSize.Width
End Sub

I would ask the author about this code but I cannot figure out how to contact the author. My question is how I would add text to this combobox. I want a box with images and a line of text as a kind of descriptor. Any ideas?

Hi, I am new to .Net and working with threads for the first time. Please review the code below.

Dim t As Thread
t = New Thread(AddressOf Me.GetValue) ' GetValue is a procedure
t.Start()

In GetValue, I want to get some data from the DB and fill in a combobox. However, when the following code in GetValue executes -

str = "select ID from ABC"
DA = New OleDbDataAdapter(str, ipcon)
DS = New DataSet
DA.Fill(DS, "rec")

- the control is lost. i.e: the next set of statements (to fill the combobox with the dataset values) do not execute. I am not sure why such a thing is happening. Is there some way to handle this threading issue that I am missing? Please help.

With Best Regards,

Mayur

Try Instantiating the Datatable on the main thread before you start the second thread:

<br />
Dim dt As New DataTable("dt")<br />
<br />
	Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
		Dim thrFillTable As New Threading.Thread(AddressOf FillTable)<br />
		thrFillTable.Start()<br />
	End Sub<br />
<br />
	Private Sub FillTable()<br />
		Dim c1 As New DataColumn("Number")<br />
		dt.Columns.Add(c1)<br />
		Dim dr As DataRow<br />
		For i As Integer = 0 To 10<br />
			dr = dt.NewRow<br />
			dr.Item(0) = i.ToString<br />
			dt.Rows.Add(dr)<br />
			'Next line is just to waste time <br />
			'so you will see combo has no data <br />
			'till thread Is finished<br />
			Threading.Thread.Sleep(2000)<br />
		Next<br />
		Me.ComboBox1.DataSource = dt<br />
		Me.ComboBox1.DisplayMember = "Number"<br />
	End Sub<br />
<br />

How do you expect a single Audio Output device to play two independant music files?

How do you expect the user to comprehend or listen and work on your application with mixed up audio?

ya thats y wanna know anyone have other device cause i only know use the mediaplayer... u have any clue?

Dave Kreskowiak7-Mar-06 4:37

Media Player will only play one thing at a time, so you'll have to use a library that can do mroe than that, like DirectX and it's DirectSound library.

Sorry, I don't have any examples because that's no my area of expertise or development work. Google should be able to get you hundreds of examples though.

In every DirectX game I've every played... And without using MediaPlayer.

It's not a problem with VB.NET. It's a problem with the audio library your using. Perhaps searching for DirectSound examples might help?
