Only three things you need to know,

1) Option Explicit
2) AndElse, AndOr (OMFG)

Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS.

Start with the
ASP.Net QuickStart tutorials[^] and make sure to choose C# as your default language. Or Windows Forms QuickStart[^] depending on if you are doing web or windows apps. Once you have a grasp on the basics you can better evaluate other courses.

In my opinion, neither ASP.net nor WinForms is "the basics" -- new developers should learn "the basics" of the language before attempting ASP.net and WinForms.

That is a very purist point of view. For many people if they don't apply what they learn to real situations they won't absorb it as well. And to me, you don't really know the basics if you can't produce something useful. If I say I have a basic knowledge of chess I would be implying I could actually play a game start to finish. Using your definition of the basics it would only imply I could identiy the pieces.

Of course.

The programs that were assigned when I first learned to program are not applicable to real situations -- they teach the fundamentals.
It's the same way they teach sports -- learn each part separately, then show how to put the pieces together to play a game.

T M Gray wrote:

Even when I was just learning I took it upon myself to write programs I found useful using the techniques that had been covered to that point.

T M Gray wrote:

I seem to recall reading about a chess teacher who teaches kids one piece at a time -- some exercises that teach just how knights move, just how rooks move, etc. and how they can be used together. And only after the students have become familiar with each of the pieces, starts to mix the pieces together.

A better, more structured, teaching technique is more likely to produce better practitioners.

It seems there are a lot of "developers" here who learned the easy way and never learned the intricacies of for loops -- their educations are stunted by not getting the fundamentals the way we old dogs did.

I watched several SQL related LearnVisualStudio videos a couple of years back and found them to be somewhat useful.

If you're looking for an introductory general purpose programming course, I highly recommend this[^] one @ MIT OpenCourseware. I'm also a huge fan of Stanford Engineering Everywhere[^] and am currently wading thru their course on Machine Learning[^]. Btw, SEE also has a great "Programming 101" course that features the venerable Karel (the Robot).

Hi Ravi
Just had a look at the SEE courses at Standford and they look like something that is useful for me. These courses in combination with some good textbooks is probably what I would go for. Thank you very much for the valuable links.

Two questions on Application Version information

Dewald23-Jul-10 1:10

Dewald

23-Jul-10 1:10

In AssemblyInfo.cs

1. What is the difference between AssemblyVersion and AssemblyFileVersion? Why would you specify different values for the two different attributes?

2. More importantly, I see the following comment in my AssemblyInfo.cs file:

// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]

This sounds like a neat idea so I thought I'd try it. But, when I access the version info in my app at runtime, using Application.ProductVersion, it still only returns the string "1.0.*". What am I doing wrong here?

Don't you need to uncomment for that to work?

Here are MSDN documentation about AssemblyFileVersion[^] and AssemblyVersion[^]

And what part of this is giving you a problem?

And why are you using .INI files anyway - they pretty much went out with Win98!

assuming the order is not important and all keys are unique, I would store all this "key=value" information into a Dictionary<key, value>. If order is relevant or duplicate keys could exist, a List<KeyValuePair<key, value>> could do. And use string type for key, and probably for value too.

Do you mean replace like with the "C-Preprocessor"?

Using two arrays is not the way to go in any case.

Triggering an event from another class?

Hi,
Scenario:
I have many user components added to a form. I wish to do some information reporting from each user control to a centralized destination, where many form can subscribe and acquire the information.

I have a class named MiscFunctions, contains an informationEvent handler which each forms subscribes too rather than subscribing to each UI component.

I want to trigger that event present in Miscfunctions class from my UI components with some arguments, and all my forms subscribing to an event in miscfunctions to listen it.

Any help please?

Re: Triggering an event from another class?

I assume you are using static Eventhandlers on your Miscfunction ...
what you need is another static method that is used to raise the event when ever you want, hope I got your question

//this goes in your miscfuncition class
 static event EventHandler commonHandler;
 static void raiseCommonHandler(object sender, EventArgs e)
 {
      if (commonHandler != null)
          commonHandler(sender, e);
 }


//component class
//to raise the event 
 MiscFunction.raiseCommonHandler(new object(),null);

Re: Triggering an event from another class?

You need to create and call a method in your MiscFunctions instance (or static class) that raises your custom event passing an instance of your own event args class (derived from System.EventArgs) as a parameter.
