C# Reflection issue [C# Reflection issue]

Árni Gunnar Ragnarsson — Mon, 19 Oct 2009 11:03:26 GMT

Hi guys and gals.

I am having a problem with reflection, and accessing sub-classes. Let's take a look at this structure:

[code language="csharp"]public class Master { public int ID { get; set; } public string Name { get; set; } public Child FirstChild { get; set; } } public class Child { public int ID { get; set; } public string Name { get; set; } } [/code]

If I want to get the value of the Name property on the master class I can do this:

[code language="csharp"]string name = item.GetType().GetProperty("Name").GetValue(item, null).ToString();[/code]

But If I want to access the value of the Name property of the FirstChild, I am stuck. I have read StackOverflow from cover to cover trying to find out how to do this ... do you have any insights ?

And I know reflection is performance heavy, but it's used in very few cases in our system, but getting this to work would simplify things a great deal.

Team Foundation Server overkill ? [Team Foundation Server overkill ?]

Árni Gunnar Ragnarsson — Tue, 18 Aug 2009 11:58:33 GMT

Hi guys ... now I turn to you for advice, and not on how to solve The Worlds Hardest Riddle.

The thing is I have just been accepted into BizSpark, and get Visual Studio TFS edition, and the server and all items needed. Right now we are using VS 2008 Professional and Visual Source Safe 2005.

I have been reeding up on TFS, and am thinking it's a bit of an overkill for a team size of three developers.

But we are growing, and I see great things in the future for our tour operator solution, ODIN.

So the question is, should I stick to VS 2008 / Source Safe or upgrade to VS TFS with all the bells and whistles, though we currently are only three developers working full time.

Number conversion and decimal accuracy [Number conversion and decimal accuracy]

Árni Gunnar Ragnarsson — Wed, 20 May 2009 16:42:54 GMT

Hi guys (and gals) ...

I have a very tricky problem around number conversion, decimal accuracy and calculations that has me scratching my head for a few days now.

In the db I have values in columns of the datatype decimal(18,2). I want to have an accuracy of 2 decimal places throughout my application and in the db it works fine.

When I am resolving the data coming from the database in a dataset, things go wrong:

float payedTotal = float.Parse(r["col_name"].ToString());

If I check the value of r["col_name"], it is 555.65, with two decimal places as expected. The float value however has the value 555.656, and rounds up to 555.70 when I display it in my application.

Am I missing something here ... or should I do the conversion and datatypes in some other way ?

I tend to agree on the complexity issue .... why are there so many projects, and why are the controllers sooo huge. I have worked quite a bit with MVC from Preview 1 and I have never felt the need to over-complexify the code like this.

I also agree with his point on code consistency .... don't you guys have internal guidelines for how you code ?

Could U add to the title of each thread / title in the thread list, the user name of the user who posted. The user name is now below the avatar, but it would be nice to have it in the title bar ... like this:

now: #Jun 12th @ 9:11 PM
should be: #Jun 12th @ 9:11 PM by Zeus

Just makes it easier to read who created the post and when ...

We up here in Iceland had a 6.1 force earthquake today .... I was driving to our office at the time and did not feel a thing, but when I got up all the stairs, the lights were still swinging.

We prepare for this kind of thing, and not one house collapsed, but some were damaged and things fell on to the floor, but no major damaga, fortunately ....

Hey guys and gals ...

I'm off to sunny Spain tomorrow for some well needed Rest&Relaxation ... and I am leaving my trusted Dell laptop at home this time :)

It will be strange not being in touch with the outside world, but good at the same time ...

How would U feel if you would be cut off (so to speak) for a period of time ... would you go insane ?

Windows Service using FileSystemWatcher [Windows Service using FileSystemWatcher]

Árni Gunnar Ragnarsson — Mon, 03 Mar 2008 12:01:34 GMT

Original file here

Hi guys.

I am trying to develop a simle windows service (my first windows service) that watches a folder on a server. It uses the System.IO.FileSystemWatcher class to watch a folder, with only the created event raised and the FileName NotifyFilter.

The thing is, it works for the first 1-3 files I drop into the folder, imports into the DB without issues.

But when I drop the 4th file and onwards, I get a file is locked error.

I am always dropping in new files, not files that are already in the folder.

Anyone have an idea as to why the files are beging locked ?

new Object Schema [new Object Schema]

Árni Gunnar Ragnarsson — Fri, 25 May 2007 15:24:17 GMT

Hi guys ...

I am thinking one thing over, and needed some input on a friday :)

I am developing a system where entities have a supplier. Just one supplier per entity.

When creating and updating the entity I need to pass the supplierID to the stored procedure.

So I have 3 choices:

1. Pass it as a seperate variable:
public void Update(Entity entity, int supplierID) { ... }
public class Entity {
    public int ID;
    ...
}

2. Pass it as a seperate sub-entity under the entity:
public void Create(Entity entity) { ... }
public class Entity {
    public int ID;
    public Supplier Supplier;
    ...
}

3. Pass it as an ID on the entity:
public void Create(Entity entity) { ... }
public class Entity {
    public int ID;
    public int SupplierID;
    ...
}

Which of these 3 choices would you choose ??

HP computer problems (updated) [HP computer problems (updated)]

Árni Gunnar Ragnarsson — Wed, 06 Dec 2006 15:28:22 GMT

Hello all ...

I just wanted to vent out some of my irritation regarding my almoust new HP computer.

I bought a HP desktop computer this july when my very, very old computer completely broke down. I opted for HP because of price and availability, I could not wait a week for a Dell (it takes at least a week here in Sweden).

I installed 2 extra hard disks and another DVD drive (which I never use btw). The HP has AMD 3800+ X2 dual core CPU, which seems to be running a fever all the time. The fans just keep on blowing no matter what, regardless if the computer is almoust idle.

I just installed SpeedFan and it says that Core heat is 51°C. I just don't know what the matter is ...

Any of you guys experienced similar issues or have any advice ??

Synergy for dual computer setup [Synergy for dual computer setup]

Árni Gunnar Ragnarsson — Fri, 13 Oct 2006 23:37:59 GMT

Hello everybody ... nice to be working on a saturday night :s

I came across Synergy just a few minutes ago. In my home (and only) office I have a laptop and a desktop computer. I sometimes work on them both, and was thinkin of buying a KVM to connect my keybord and mouse to both computers.

Synergy eliminates that problem. It is a software that shares the keyboard/mouse from one computer to many. You just install the software, set up one computer as the host, and connect the other computers to the host (install the software on those computers too).

Now the computers I have work together as a single computer with multi-monitor setup. It's friggin cooool. It's a bit of a hassle to set up, the UI is totally insane, but this sh** works ... and it just made my weekend :D

Blog post: The time has come.

As you can read in my blog post here above, to day is the first day of the rest of my career. Today I start work for my own company, as the only employee (let's just hope that is temporary).

ZEUS web works is the name, and I already have some clients that I will work for every month. I am going to specialize in on-line admin tools for comanies, web based internal systems if you will.

Right now I am putting the finishing touches on phase 1 in a pretty big system for 3 travel companies (1 company, 3 brands). And I have started work for a small company in Iceland for their customer admin tool.

And the best thing is that I managed to sell my former employer a considerable amount of work every month ...

So I hope the future is bright, I am very excited ... I just wanted to share my news with everybody here.

:D

Well ... I finally finished my new site and put it out there. It has been down for the last few months, and I took the time from the World Cup and my coding duties to design a totally new site and put up some content there.

Would be grateful if you could go through the site and point out something that is not working (if you can) ... I tend to get pretty blind on my own projects :s
