VB 2003, callbacks do not work

[tommy_jo]

I tried to make a new project in VB 2003 and I wrote this code:

http://daytrading.se/vbcode.txt

I also added IESignal to references.

I still don't get the callbacks but I can see that it's beeing received in eSignal app.

what am I doing wrong?

Call back problem

Does it call back esignal_OnQuoteChanged as soon as you try to access the Quote.dbid or any other parameter? Because I think I am having a same problem. I am using VS 2005, are you using the same version as well?

Thank you

Private Sub esignal_OnQuoteChanged(ByVal sSymbol As String)
Dim quote As IESignal.BasicQuote
quote = esignal.GetBasicQuote(sSymbol)
lblInfo.Text = "BID=" & Str$(quote.dBid) & " ASK=" & Str$(quote.dAsk) & " LAST=" & Str$(quote.dLast)
End Sub

no, I use 2003,

but I found the problem.

I forgot to add
Handles esignal.OnQuoteChanged


Private Sub esignal_OnQuoteChanged(ByVal sSymbol As String) Handles esignal.OnQuoteChanged
...

My problem was different. I was requesting price History for several different time intervals on ES and it was not working properly. Events were firing out of sequence, and were interupting my price HistoryRequest, so I created a class and used multi threading functionality to call each request seperatly. It is working very well. I extended that and now I receive Price Update for each new bar and update my bars seperatly on different Threads. I guess it can be extended by writting a delegate.
