I agree that locking on this is a bad call, but what about locking on a private static dictionary object when reading or writing to it from various threads?

Yeah that's fine. As a general rule, don't lock on anything you aren't certain anybody else will be able to lock on without doing stupid reflection tricks, so anything private is a prime candidate. e:

For dictionaries you may also want to consider refactoring to use a ReaderWriterLockSlim so you can get parallel reads.

Note: If you want to post back and bind to an array/list, you have to make sure that your form inputs all have names with indexes in them(like Model.SomeList[0], Model.SomeList[1] etc) and those indexes *must* be in order without any skipping. That's the only way the model binder will correctly create a list. Without the indexes, you either get a null or empty list. And if you skip an index everything after the skipped index will be ignored(say you post back for indexes 0, 1, and 3, leaving out 2 will make 3 get ignored).

If you're using all the expression overloads for Html.EditorFor/TextBoxFor/SomethingOrOtherFor then all you really need to do is use a for loop instead of a foreach. Though I'm not quite sure how well that works with rendering a partial.

EditorFor will do all of this automatically on a list, just set up the appropriate editor template.

Alien Arcana: Feb 14, 2012; You're related to soup, Admiral.

I've run into a problem with TcpListener and I can't find any documentation about this on MSDN, so I'm hoping someone here will know what I'm doing wrong.

As was suggested in my last foray into this thread, I switched to using asynch (Begin/End) methods to handle the network I/O. I believe I have most of it worked out now, but I'm having some trouble with one particular issue.

Specifically, if I call one of the Begin methods (e.g. TcpListener.BeginAcceptSocket), how do I tell it to stop listening so that I can shut down the server? There does not appear to be a designated method for this, and I can't call EndAcceptSocket without an IAsynchState to pass it. I tried just calling TcpListener.Stop, but that just seems to trigger my "accept socket" delegate getting called anyway, and promptly throwing an exception because the listener has been disposed!

The code in question:

code:

private TcpListener Listener;

public void StartServer()
{
  Listener.Start();
  BeginListening();
}

public void StopServer()
{
  Listener.Stop();
}

private void BeginListening()
{
  Listener.BeginAcceptsocket(new AsyncCallback(AcceptNewClient), null);
}

private void AcceptNewClient(IAsyncResult ar)
{
  Socket inputSocket = Listener.EndAcceptSocket(ar);

  // do stuff with the socket

  BeginListening();
}

Whenever I call StopServer() I get an ObjectDisposedException on the first line of AcceptNewClient.

Can anyone tell me what I'm doing wrong?

This is a lot more difficult than it should be our I'm missing something obvious. In wpf how do I get the celltemplates defined in a listview control in the code behind?

Either I don't understand wpf at all (very likely, New to it), or were doing some idiotic validation on controls. We're using reflection and frameworkelements to dynamically add validation logic to controls. There was a bug were validation want showing on controls in a list, working on it; and turns out they didn't implement collection logic for this method of validation. So here I am.

If you're writing "code behind" in WPF, you're not doing MVVM correctly. That's bad. Use MVVM.

This is correct behaviour.

quote:

Not handling exceptions - that's how the IAsyncResult pattern works. Your callback is guaranteed to be called, and the End... call will throw whatever exception you need to deal with.
In the case of listener socket shutdown which is what .Stop() does, it throws an ObjectDisposedException as documented on MSDN: http://msdn.microsoft.com/en-us/library/system.net.sockets.tcplistener.endacceptsocket.aspx

All you need to do is:

code:

private void AcceptNewClient(IAsyncResult ar)
{
  Socket inputSocket;
  try
  {
    inputSocket = Listener.EndAcceptSocket(ar);
  }
  catch( ObjectDisposedException )
  {
    return;
  }

  // do stuff with the socket

  BeginListening();
}

You may also want to process SocketExceptions in a few cases.

Oh, and let me mention one of my pet peeves to head it off at the pass, because I see this come up any time IOC comes up: MEF is not an IOC framework.

I know this is a few days old, but would you care to expound on that statement? I'm just reading up on IoC and Dependency Injection since it came up in this thread.

The IoC wikipedia page lists Dependency Injection as a implementation of IoC. The Dependency Injection wikipedia page in turn lists MEF as a implementation. The Ninject project which you mention as a IoC framework has "dependency injection" written all over its site (although their Wiki is having trouble at the moment).

So at first blush without actually having spent time trying to write code with either, it looks like MEF and Ninject are both DI implementations. What's your objection then? That MEF isn't a framework?

Ugh.

You don't really "format a string as DateTime". You can have a DateTime object and ToString it, and format that the way you want. Or you can have a string, and parse it, producing a DateTime object.

I'd guess you're trying to parse the string "1900-01-01 00:00:00.000" to get a DateTime object. In that case, you could try giving the string to DateTime's Parse static method, but if that chokes, you might have to give it to DateTime's ParseExact static method, and specify exactly where all the digits are.

So, roughly,

C# code:

string input = "1900-01-01 00:00:00.000";
DateTime dateTime = DateTime.ParseExact(input, "yyyy-mm- .... and so on", CultureInfo.InvariantCulture);

Edit: You can find the syntax of what years ("yyyy") and months ("mm") look like on the Custom Date and Time Format Strings page.

MEF is optimized for plugin type development. It can scan a folder for .net assemblies and find implementations of specific interfaces and make them available for your executing assembly to utilize, without your executing assembly needing to be aware at build time that the plugin assembly even exists. That's really what it's designed to be.

I recommend reading Dependency Injection in .NET by Mark Seemann, it really explains all these concepts well and gives a good overview of Castle Windsor, StructureMap, Spring.NET, Autofac, Unity (which is microsoft's IOC container) and MEF.

Let me quote him on MEF.

Mark Seemann, Dependency Injection in .NET, pg 493 posted:

Is MEF a DI CONTAINER?
There�s a lot of confusion about whether or not MEF is a DI CONTAINER. The short answer is that it isn�t, but that it shares so many traits with �proper� DI CONTAINERS that it may become a full-fledged DI CONTAINER in the future.

MEF was built for a different purpose than a DI CONTAINER. Its purpose is to provide a common framework for enabling add-in functionality for standard applications. From the perspective of a standard application, an add-in is an unknown component. Whereas the add-in is most likely required to expose a certain interface, this is about all the application knows about it. There may be zero, one, or a lot of add-ins, depending on the environment. This is different from a DI CONTAINER, where we typically know about all (or most of) the components at compile time.

When we use a DI CONTAINER as a tool to compose an application, we know about the components that make up the application, and we use this knowledge to configure the container in the application�s COMPOSITION ROOT.
On the other hand, when it comes to plug-ins, we only know that the plug-ins must implement some sort of ABSTRACTION, but we can�t compile the application with a configuration of specific plug-ins, because they are unknown at design time. Instead, we
need a discoverability mechanism.

A traditional discoverability mechanism for add-ins is to scan a certain folder for assemblies to find all classes implementing the required ABSTRACTION. However, this doesn�t address the issue that may occur when the add-in itself has DEPENDENCIES.
MEF, on the other hand, addresses exactly this scenario through its advanced discovery model that uses attributes to define consumers and their services.

A DI CONTAINER favors decoupled composition of services. This provides the greatest degree of flexibility, but comes at a cost: as developers, we must have knowledge about the components we wish to compose at the time we configure the container.
MEF favors discovery of components. This successfully addresses the issue when we know little about the add-ins at design time. The tradeoff is that the discovery mechanism is tightly coupled with the components, so we lose some flexibility.
When we consider the internal architecture of MEF, it turns out that discovery and composition are decoupled. This means that it�s possible for Microsoft to evolve MEF in the direction of a true DI CONTAINER.

On the other hand, some DI CONTAINERS offer such powerful convention-based features that they may encroach on MEF in the future.
Even today, MEF shares so many similarities with DI CONTAINERS that some of its creators already view it as one, while others don�t.

Are you reading out of a SqlDataReader? If so, why do you need to parse anything? If the column's type is nullable datetime then you can do something like this: reader.IsDBNull(0) ? new DateTime?() : reader.GetDateTime(0).

The actual line of code to parse the string is basically:

DateTime.ParseExact(row[2].ToString(), "dd/MM/yyyy hh:mm:ss tt", enUS), (It's a parameter being passed to a constructor, no I don't have a missing semicolon )

It is a date time. I've had trouble with the typing being correct so I thought "screw it, just make it a string!" because I just want to get done and move the hell on.

I guess I need to pull everything from SQL in a way that preserves types, but then I have to cast those SQLTypes to a serializable type before I serialize it because serializing SQL data types is apparently bad.

You want to use a SqlDataReader to read data from tables, and that thing has extension methods that will spit out the standard datatypes. You should not have do to any of this manually or even think about it.

I also want to repeat my recommendation that you use some sort of ORM. Coding this stuff yourself adds no value to your project and only creates more opportunities to make bugs or security risks. You're dealing with what is commonly known as a solved problem. Don't try to re-solve it.

I need to check a local folder for new files. From the UI perspective they should appear "instantly" to the user. That is, when they drop a file in this folder, then pop back into my app the file should show up in a listbox immediately. The listbox is already bound to an observablecollection, so my question is more on the folder/file checking. The only way I know how to do this is with a DispatcherTimer running a check every 1 second and anytime it finds new files just pop them into the collection.

Is that the right way to do that or should I not be running a DispatcherTimer routine every 1 second? Realistically it will only find a file maybe once a day.

Not silly, good question. The requirements for this project were: Must have local file system access and must work on PC and Mac. That narrowed it down to Silverlight only, 1 year ago when the project started. As far as I know that's still only a Silverlight domain as the HTML 5 local file access is really only supported in Chrome and even then it's iffy.

If anyone knows of a different platform that can accomplish that I'd be very interested to know. We're not going to get away from Silverlight for the foreseeable future, but I would like to know of alternatives.

Has anyone ever transferred a BUILD pass before? Due to personal reasons I won't be able to attend and I have a friend checking to see if he can pull it off and take my spot, but all the information I see implies it should only be within your company. Anyone had experience with this?

poo poo, there you go. I remember looking at mono before the project kicked off and there was some reason I didn't think it would work, however after looking again I can't see what the issue would be. Well, hindsight. Thanks for the link though.

No, but as a conference organizer I know that we don't exactly check if the curtains match the carpet as long as someone pays the transfer fee. So if your friend doesn't care and it doesn't raise issues at the office I think you could just change the name.

Speaking of BUILD, is anyone else here going? I missed the last one due to Sandy but I'm scheduled to fly out a week from Tuesday.

Does anyone know how to manually copy projects in vb.net?

I have a project I was working on, and I wanted to preserve the 'existing' condition... So I copied it to a new folder with a different name, and did a bunch more coding on it.
Problem is, it don't work anymore. There seem to be references to the first project, and all I get is a huge number of system error messages when I try to run it now.

There doesn't seem to be anyway to import stuff that works, in VB.net express 2010. Or any way to simply "copy a project" to a different location, and get all the stuff correct.... It might work in the paid version of Visual Studio, but I don't have that.

This guy says "you edit the text files with no extensions", but WTF is he talking about? ALL the files I see have extensions.

I found the FileListAbsolute.txt file and tried editing that, but the first project has a whole bunch more lines in it than the second (non-functioning) project did. Just changing the file paths of the first one and copying them into the second one didn't work. I don't know if this file is an actual build-guide or if it is just a report generated after the fact however.

This is called "source control". It is a solved problem. Use source control.

[edit]
VS2010 Express doesn't support source control integration from the IDE, but there's no reason to not be using VS2012 Express, which does. You could also limp along with manual source control from outside the IDE, but the fully integrated TFS (or TFS+Git)/VS experience is beautiful and easy to use.
