I learned C++ in high school and college. After I got out, I spent a little time working with ASP .NET. Then, for the last two years I have been a PeopleSoft developer.
I've seen a few posts with some generic advice, but I was wondering if anyone had any specific advice for learning C# and the ASP .NET framework. I have a good idea of programming concepts in general, so I'm really looking for something that focuses specifically on getting people with prior development experience into C# and ASP .NET.
Websites would be great, but I don't mind dropping some cash on a book or two.
Any help would be greatly appreciated.
Thanks,
John

Thousands if not billions of programmers have gone this way: Coming from C/C++ and going to C#/.NET.
Just take your Google/Altavista/Yahoo/whatever and search for it. I'm sure you'll find tons of materials/free eBooks...

Well I think 1,000,000 persons are not that much relative to the whole universe.
So I really think they are amongst us - strange behaving ever-pale people eating/drinking only junk-food/coffee. Better beware, they might be also after you.

You're right. I confused something. So it's really an invasion. I will lock myself, too...

Started skimming this, and so far it seems exactly like what I need.
I've found a few sites just by searching, but nothing as specific as this.
Thanks.

C# articles on this site are really good, if you know where to look. I came from a C++/Java background, and I owe credit to this site for most of my learning of C#.

I can attest to that also. CP is one of the better sites to begin learning. The articles range on pretty much any topic you are looking for, and if they don't the forums can cover what you are missing.

Yup. Even for some of us veteran programmers.

I was a VB-based ASP.NET developer using MC Access and MS SQL 2000. I learned C# 2005 and C#-based ASP.NET 2.0 using MS SQL 2005 through two excellent books: Learning C# 2005 2nd Edition from O'Reilly and Beginning ASP.NET 2.0 Databases from Apress (focusing on ASP.NET/C#2005/MSSQL2005). I downloaded the Microsoft Visual C# 2005 Edition for free, until I had the funds to update my copy of Visual Studio to 2005 from an earlier version.
To learn the most recent versions of ASP.NET and C#, in addition to a firmer understanding of OOP, I have been reading Beginning C# 2008 Objects and Pro ASP.NET 3.5 in C# 2008, both by Apress.
I strong recommend the O'Reilly Learning C# 2005 or more recent versions for a basic understanding of C# concepts.

Hi all,
I have a web service which I want to implement on multiple servers and which can communicate with each other. (Meaning reusing the same web service on the different servers) I am currently using a proxy class which i created with wsdl.exe in order to call the web service from any other component (web page, windows service, etc). That works fine, giving it the Url. Now the problem I have is communicating between one web service and another, as when I add the proxy class to the web service, in order to create an instance of a webservice and give it a URL, the namespaces, functions etc already have definitions for them.
To simplify:
Web page to web service communication
Web page has web service proxy class, an instance of web service is created, a url is given and the web service methods called - works fine
Web Service to Web service communication
I add the proxy class to the web service and it gives me errors, namespace already defined, etc etc, obviously because the proxy class is of the same web service I am trying to add the class to.
So effectively my question is this. In order to reuse my web service over multiple servers and call methods between these web services, what do I have to do?
Thank you very much in advance for any help

Hello friends,
I have an application that reads file properties and stores them in an Access database. It reads the following properties:
size, file's icon (if it has), dates (modified, accessed and created), file attributes (read only etc...), artist name, album title, album year, trackNumber durtion, genre, bitRate, frameRate, sampleRate, height, width, owner, author, title, subject, category, pages, comments,copyright, company, description, major version, minor version, revision number, product name, major product version, minor product version, product revision.
Any advice on how to do that. I decided to use the GetDetailsOf method, but it was only when I started coding, that I realized that the GetDetailsOf method returns strings, and that would mean that I have to manually parse the returned data to extract the required info. Also, I want to keep unmanaged code inside my app. to a minimum.
Problem 2:
The same app. has a Windows Explorer like interface and has pretty much the same purpose. I'm using a ListView and a TreeView control to provide the same UI as Explorer.
Now I need a way to preview the file that the user has selected, much like Windows Explorer. The file can be an Image file or an audio/video file.
The mechanism I'm using now for this feature is a UserControl which has a Preview() method in which I determine the type of the file based on extension and then add a proper control to my UserControl.
The real problem is how to preview a video. I'm currently using the Microsoft.DirectX.AudioVideoPlayback.Video class to provide this functionality. But it has many annoyances.
1. It doesn't have a parameterless const. So I cannot simply create an instance of the class without providing it a video file path.
2. Every time a new instance is created, it pops up a new window the size of the video, and to position it inside my controls bound, I have to assign to its Owner property. To do that, I need a class Instance and that again means a new window.
Please suggest.

Hello everyone,
I'm trying to make an questionnaire and I want to do this with enums.
For example:
enum Color{ Black, White }
enum Height{ cm_10, cm_20 }
With this information I want to show each enum in a panel, where you first have to answer the color and then the height, and it has to be extendable. But I don't get it working.
Can you help me, I would like to do it something as following:
private void askQuestion(Enum e)
{
String[] ss = Enum.GetNames(typeof(e));
putOnScreen(ss);
}
private void overall()
{
ArrayList ar = new ArrayList();
ar.Add(Color);
ar.Add(Height);
foreach(Enum e in ar)
{
askQuestion(e);
}
}
I guess it should be possible, but I don't know how.

If you put your questions inside enumerations, you haven't got an extensible mechanism. When I've developed this type of application in the past, I've always used a database. Roughly, this breaks down into:
Topics
Questions
Answers
AnswerTypes (textbox, multi-select, etc)
Scores for answer
This makes for a much more extensible questionnaire application.

You are totaly right about that. I'm going to make it with a database.
But if we asume that I would do it the way I described above (just to learn something), is this possible or possible but not done or something else?
|
|
|
|
|
It's possible - but not advisable. BTW - using ArrayList isn't a good idea. I assume you're not saddled with developing in .NET 1 or 1.1.
|
|
|
|
|
I'm used to developing in .NET 2.0 and 3.5
ArrayList was just a suggestion, I prefer just arrays, like Enum[] e = { enum1, enum2 };
But that didn't work.
If you say I shouldn't use it, I'll just go and work with a database.

Good afternoon all,
I'm learning to work with 'Lists'
I've set up a list of 'zooAnimals' and in the list i've added objects as they have been created.
zooAnimals = new List<Animal>();
newcat1 = new Cat(cat1, catPen, fircat);
newcat2 = new Cat(cat2, catPen, seccat);
newtig1 = new Tiger(tiger1, tigerPen, firtig);
newtig2 = new Tiger(tiger2, tigerPen, sectig);
zooAnimals.Add(newcat1);
zooAnimals.Add(newcat2);
zooAnimals.Add(newtig1);
zooAnimals.Add(newtig2);
I would like to now step through the list to perform certain actions when a button is pressed.
For example - the form has a number of buttons on it - 1 being for individual groups of animals to eat().
I tried with
foreach (Cat thisCat in zooAnimals)
{
if (thisCat.hunger == 7)
{
thisCat.hunger = thisCat.hunger - 5;
}
}
but this code throws an InvalidCast Exception......
Unable to cast object of type 'Zoo_Animals.Tiger' to type 'Zoo_Animals.Cat'.
Is there a way of stepping through the list to do this ?
Thanks in advance !
Neil

If you're using .NET 3.5 you can use
foreach(Cat thisCat in zooAnimals.OfType<Cat>())
{
...
}
otherwise you'll have to check each item
foreach(Animal animal in zooAnimals)
{
if(animal is Cat)
{
...
}
}

Thank you very much indeed - worked a treat !
