C# listner application

Thu, 26 Nov 2009 10:18:02 Z

I have a desktop application in developed in C++. This queries and updates a Global distribution database by calling services.

Can I have a listener on the user desktop which can track the key strokes on the desktop application and on a certain key stroke on the desktop application should be able to get the unique identifier of the data, open another application, query the database and display information for that unique id.

Automatically Connect to Service

Mon, 23 Nov 2009 14:50:50 Z

Is there a way to have the WPF client automatically connect to one of the web services? I'd like to have it automatically connect to the TradeServiceWCF.svc, without having to click the Connect button on the config tab.

Thanks!

Great job creating the real world app! It is very useful for learning and would be even more useful to include the install project as well... Is this possible at all?

Fri, 13 Nov 2009 08:01:27 Z

Hi All,

I'm using a third party Grid control which is not getting populated with the data available in dataset and the grid contents are shown as blank. Also a red cross is displayed inside the grid control. But the Grid control is scrollable (like it has the rows populated). The application which I’m using is multi-threaded.

Please help me out in solve this problem.

Config Services and ESB

Fri, 05 Dec 2008 14:17:53 Z

Hi Greg!

It's been a long time since we discussed on the road-ahead for Config-Svcs. I'm sure you have some plans already on this. Anyway, I was just thinking - now that you have given us a platform to create and host SERVICES that integrate within or across n/w's over standard protocols and be able to participate in LOAD-BALANCE and FAULT-TOLERANCE, How about the possiblitiy to extend this CORE-PLATFORM in order to allow registering, discovering, publishing & scubscribing, mapping and management of services in a loosely-coupled manner.

I guess you got what i'm saying - basically How about extending Config-svcs to support light-weight Enterprise Service Bus (ESB) features. I know it's outside the scope of your project probably, but what is your take ? or do you see any such open-source products that can be aligned with Config-svcs to achieve this goal?

Kindly share your views.

Regards

Missing configuration modes performance document?

Sun, 08 Nov 2009 23:00:49 Z

Hi,

At the bottom of the TechnicalOverview.pdf file, it says the following:
"Please refer to the benchmarking whitepaper on the StockTrader MSDN site for performance/throughput benchmark comparisons based on the application and the various modes it supports."

Now, I believe that I have seen this document before, which showed throughput stats for various configuration modes for the Stocktrader application. It was NOT the Websphere vs .net comparison document. It showed things like having the various layers on different machines vs. the same machine, etc. And it showed how many transactions per minute on each configuration.

I cannot for the life of me find this document. I'm sure with a much more extensive search of my files I'd probably come across a copy of this document, but I'm wondering where this now is? Was this part of another document with that detail removed, or have I missed this?

Regards, Tony

Java clients load balancing/failover of Configuration Service

Tue, 27 Oct 2009 17:39:59 Z

Hello,

Is it possible for Java clients to take advantage of load balancing/failover?

As I see it is possible for NET clients because of they must use base classes.

What about Java clients or non-NET clients?

Thanx

My code is as fallows

protected override void OnStart(string[] args)
{
fileSystemWatcher1.Path =@"D:\Test_File\Test.html";
}

private void fileSystemWatcher1_Created(object sender, FileSystemEventArgs e)
{
MailMessage mail = new MailMessage();
mail.To = xyz@abc.com;
mail.From = def@abc.com;
mail.Subject = "Alerting You";
mail.BodyFormat = MailFormat.Html;
mail.Body = File.ReadAllText(@"D:\Test_File\Test.html", Encoding.UTF8);
mail.Attachments.Add(new MailAttachment(@"D:\Test_File\Test.html"));
SmtpMail.SmtpServer = "kptsc.vfstc.local";
SmtpMail.Send(mail);
File.Delete(@"D:\Test_File\Test.html");
}

but for the first time its working fine,but for the second time its throwing error as "The process cannot access the file 'D:\Test_File\Test.html' because it is being used by another process"

Thu, 01 Oct 2009 04:49:34 Z

Hello, everyone,

I followed the tutorial exactly three times and always stopped the same step where the Order Processor could not be activated. There is nothing wrong when I followed the tutorial steps except that there is a firewall blocking issue caused by required port 6004 to be created. The following is the error message that might be helpful for you to help me out:

I have finished the Step by Step Walk-through and get no problem at all. My operating system is Windows 2003 (Chinese), is the windows version a problem?

If someone knows how to resovle this problem, please provide helpful hints, Thanks!

Service startup on server reboot

Thu, 17 Sep 2009 02:30:58 Z

Hello,

We ran into some startup issues when rebooting a server, when our the NT service based service tries to connect to sql server to get its configuration data, sql server is not yet running. Creating a startup dependency on MSSQLSERVER at the very least doesn't seem reliable; it seems that the service reports as started before the databases are actually available, so it still fails. This of course puts everything in a failed state, although when you first look at the service snap-in, things appear to be running. Anyone have a good solution for this so far?

Maybe a more interesting question, what happens when you restart a machine that a configuration based service is on and the sql server instance that holds the repository is remote, and also off?

Thanks,
Darren

The server failed to load application '/LM/W3SVC/1/Root/Trade'. on XP IIS 5.1?

Fri, 04 Sep 2009 20:29:01 Z

I just installed IIS 5.1 on XP SP3 and enabled MSMQ. I then installed the Stock Trader 2.04 application.
The install completes just fine and creates the databases correctly, and I followed all the post-install steps.
When I attempt to access the localhost/trade app, I get the 500 error screen.

The event viewer provides this message:

The server failed to load application '/LM/W3SVC/1/Root/Trade'. The error was '8007053d'.
For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

From what I've found online, this looks like a metabase issue, but I couldn't find much.

I uninstalled IIS and stock trader and reinstalled but keep getting the same issue.
I'm hoping someone can offer some assistance with this.

Thanks,
-Chris

Any chance to support callback?

Mon, 17 Aug 2009 14:07:05 Z

Hi Greg,
I just want to ask if there is any chance to add callback support in the next release of the Stock Trade demo app?
also, so far the demo is a good starting point for tackling WCF, but it doesn't provide a real-world experience.
To be specific, i want to use WCF to develop an Enterprise Trading App, so i hope you can give me some ideas where i can start.
I apperciate your feedback.

I've tried downloading the .Net StockTrader installation package several times, but when I try to install, I keep seeing "This installation package could not be opened. Please contact the application vendor..."

I've downloaded in IE, FireFox, and Chrome, and the download behaves the same in all cases. Please advise.

Why can't I view the whole content of "Repository Creation Tool" ?

Hi,

After the installation of stock trader app, I tried to follow the instructions to create a database configuration under Repository Creation Tool. However, I couldn't view the whole content of "create configuration database" page but only the part of setting. There is NO scroll bar to let me scroll down to contnue the setting after "Database Server". It still doesn't work even I change the resolution or the font size of my LCD.
Can anyone help.... ?

Regards,
Winston
