I'm trying to develop a VB .NET program receiving up to the second stock quotes. I've tryed this simple test program to figure out what the problem is and it exits after less than 5 min without a reason. Can anyone help, please. Here is the code for the form.

Private s1 As String = "KLAC"
Private s2 As String = "NVLS"

Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
End Sub

Private Sub IQFeed_ReceiveMessage(ByVal sender As Object, ByVal e As AxIQFEEDXLib._IIQFeedXEvents_ReceiveMessageEvent) Handles IQFeed.ReceiveMessage
If (e.message.Chars(0) = "Q") Then
Dim message As String() = Split(e.message, ",")
If message(1) = s1 Then
lstOutput.Items.Add("S1 " & message(3))
ElseIf message(1) = s2 Then
lstOutput.Items.Add("S2 " & message(3))
End If
End If
End Sub

See very simple program, why does it exit...

Look at the following thread : posted a few days ago and you will have your answer.

You will probably need to implement the socket interface like most of the .net users.

I might be wrong, but it looks like you are using IQFeedX instead of IQFeedY.

OK I see now that I should be using IQFeedY, but I don't see any examples for VB .NET. I tried the AX control, but it would shutdown my program right after it loged in. I'm currently trying to use the Com direction from reading other problems in this forum, but still having problems with tham. Does anyone have a simple watch symbol program in VB .NET that they could send me.

We have two .NET examples, one is CSharp and the other is VB. The VB one uses IQFeedY, and would be a good one for you to review. It is installed with the developer install package, and you can acccess the code/run it from Start menu->Programs->IQFeed->.NET Examples->Level1 VB.NET COM.
