I have some vague recollection of this feature existing, but it wasn't until this last week that I needed it again:

When working on a project with multiple executables within the same Solution, Visual Studio can Start all of them when you debug if setup for it.

Simply right-click the Solution and choose Properties. Choose Startup Projects from the left pane, then select the Multiple Startup Projects radio button.

For each project listed, you may choose to start it normally or without debugging. By using the Move Up and Move Down buttons, you may change the order in which the projects start!

If only I would pay attention to the tool tips for a program, I would have been using this tip a long time ago:

To show or hide the formatting marks in Word (spaces, tabs, paragraphs, etc.), type ctrl+*. Quicker than using the mouse and a lot less likely to cause a repetitive stress injury.

This is kind of an old trick, but one I sometimes forget:

When editing in Visual Studio, simply hold down the Alt and Shift keys while typing Enter. This will put Visual Studio into full screen mode and provide a much larger working space.

In my networking class this term, we built a simple chat program. It’s nothing fancy – type in your name, a server, and see what others are posting.

I decided to learn a little bit about .NET Remoting in this exercise. I found numerous examples (including some chat programs) demonstrating how easy it was to create such a program and felt confident with choice I had made. The only thing I had to add to the consolidation of information I had found was a way to select the server one was using.

Yeah… just that.

Now, it’s entirely possible that I missed some nugget of information out there and even that there is a different (better?) way of doing this, but I think I learned something of value through this exercise.

First, the app.config file I was using that worked fine was as follows:

<?xml version="1.0" encoding="utf-8" ?>
          type="LeChat.Broker.LeChatBroker, LeChatBroker"
            <formatter ref="soap" />
            <formatter ref="soap" typeFilterLevel="Full" />

With this file, one only has to load the settings with:

RemotingConfiguration.Configure( "AppName.exe.config" );

Easy! Of course, if I want to change the name of my server, what do I do?

Some of the learning I had:

The app.config file is meant to be a quasi-read-only file. Although one can write to it through various means, it is loaded at the launch of the application and cached for use throughout the activation – once the program is running, changing the app.config would make no difference.

All of the examples I found for loading the configuration in code were nearly identical:

HttpChannel channel = new HttpChannel( 8888 );
ChannelServices.RegisterChannel( channel );
      typeof( LeChat.Broker.LeChatBroker ),
      "http://" + serverName + ":7777/LeChat",
      WellKnownObjectMode.Singleton );

This did not provide all of the parameters needed to make the two-way communication possible between the client and the server. In fact, kept going back and forth between having the chat text show up only on the server, or only on the client – depending on whether I registered a … ServiceType, or a … ClientType. Aarrrggghhh!

Finally, I started looking at the overridden constructor on the HttpChannel. I saw something about a IDictionary of ‘properties’ and realized I might be on to something. I started reading about SinkProvider’s and felt even closer. Finally, I had constructed the complete block of code that allowed my little chat program to work and I could insert any server name I needed to:

IDictionary configurationProperties = new Hashtable();
IDictionary serverSinkProviderProperties = new Hashtable();
configurationProperties.Add( "ref", "http" );
configurationProperties.Add( "name", "client" );
configurationProperties.Add( "port", "0" );
serverSinkProviderProperties.Add( "ref", "soap" );
serverSinkProviderProperties.Add( "typeFilterLevel", "Full" );
SoapClientFormatterSinkProvider clientSinkProvider =
      new SoapClientFormatterSinkProvider();
SoapServerFormatterSinkProvider serverSinkProvider =
      new SoapServerFormatterSinkProvider(
        serverSinkProviderProperties, null );
HttpChannel channel = new HttpChannel(
      serverSinkProvider );
ChannelServices.RegisterChannel( channel );
      typeof( LeChat.Broker.LeChatBroker ),
      "http://" + serverName + ":7777/LeChat" );

This turned out to be a more substantial investment than I had expected. I did get a chance to learn more about how this stuff works and I’m looking forward to reading Ingo Rammer’s book " Advanced .NET Remoting" to learn more. However, I felt compelled to document what I did so that I can re-learn it all if needed.

This month's PADNUG meeting is looking like it will be pretty darn good. Not only will it be Rory's last hurrah in the Portland area for a spell, but he will be assisted by the lovely and talented Chris Sells!

This should prove to be a great evening to introduce oneself to the wonders that are PADNUG. Not to mention that in Chris' absence, I will be bringing the boxes of swag to the party! You, too, could be a lucky winner of one of these beautiful gifts!

Another Portland Nerd Dinner has come and gone. Fortunately, this time I got pictures to savor the day a little longer.

Being the last PND that we will likely see Rory at for a while, it had a special meaning for all in attendance. Chris Sells brought a fabulous piece of artwork and allowed all to sign the back as a memento to Rory.

This PND seemed to go longer than usual. It may have been the fine cuisine, the excellent company, or the brawl that nearly started nearby, but something just kept the attendees enthralled with the meeting.

Rory, we’re going to miss you while you are gone. We just may need to get a cardboard cutout of you to stand in!
