Dear !
I know you are the best programmer and very famous on Codeproject website. I read your profiles and I was proud of you. I think you are so good. In the past time, I though that I would depend on your help. But I don't know whether you have free time or not and whether you are ready to help me ... so I didn't do ... Now , the time is not enough. There is only about 6 days to me complete my project but there are some problems that I can not do because I know my knowledge is so bad. This is attachment for my project, that is a C# Project and compressed into zip fie. It only compiles and run it ...
There are some problems :
- I can't use V-H scrollbar ...
- I can't use Serializable to save and load binary file.
- I can't perfom cut/copy/paste object.

Best regards !

Hi there for my learning purposes I created a .exe from Visual.net . I gave that program to my friend to use it but it said that certain dlls were missing. IS there a way after creating the exe on my machine it will work on his machine if he donesnt have the .NET frame work ?
wud appreicate ur help

Afraid not. Your friend will have to DL the .NET framework for it to work.

Absolutely correct but you should remember that it DOESN'T mean your user has to have Visual Studio .net or the .NET Framework SDK installed. All they need is the .NET Framework Redistributable which should be on your VS.NET installation.
I have seen this misconception surface quite a bit!!!
If you are deploying your code on CD you can include it on there... otherwise as has been said they will have to download it...

If You have DataSource=anyTable You have no master/detail  . Should be DataSource=anyDataSet, DataMember="anyTable". See HitTest(), HitTestInfo, HitTestType in help

Hello all (My first Post here  )
I would like to start learning C# next week. Up untill now I have experiance in C, C++ and Java but I've only done console applications.
The Q: With which books should I start with? I'm not interested in books that spend 2 chapters on flow control but on the other hand I rather pass books that "convert" you from Java to C# (as "C# for Java programmers"...).
I thought about 3 options :
1) Programming C#, Jesse Liberty.
2) Microsoft Visual C# Step by Step, John Sharp.
3) C# How to Program, Deitel.
For a first book I would prefer learning only about console applications. later I wil ask about Visual C# Books .
So what would you recommend?

Welcome to .NET!
Petzold also has a good book out on C#.

Hi Rocky,
I read some reviews on Petzold's book and came to the conclusion that the other 3 I mentioned were better. I just have to pick one of them (let Petzold be the 4'th choice - you convinced me it's good too  ). As I said, the main objectives are:
1) The book shouldn't elaborate too much about basic things such as flow control, variables...
2) The book should concentrate only on console applications.
With that in mind, what would the best choice?
Thanks for your answer.

Those look all three too beginner orientated.
I suggest that you be brave, read the excellenet MSDN docs (you just want to know the syntax or C# really, further is pretty much 100% JAVA) on C#, and then for the hard part tackle the .NET framework docs.
We use a Dietel How to Program C book in CS 1 , but that is really beginner...

So you actually recommend not to buy for now any book? Use only MSDN?
P.S
I have accidentally written "Microsoft Visual C# Step by Step, John Sharp" while explicitly saying that I'm not interested in any "visual" stuff for now. I ment "Inside C#, Tom Archer". Sorry.

Maybe get one book just to get the hang and read on the loo or in bed, but for me MSDN is more than sufficient

Me too. I learned (?) C# from MSDN, Google and CP.
I think compared to C++/MFC developers, Java developers can easily jump into C# bandwagon.

I was in your exact same shoes a few months ago. I first bout Petzold's book, but it was really more about deep internals of Windows than just learning the C# language. A good reference, but not good for learning Windows programming in C# for first time.
I went to Amazon and made a list of all the "contenders" and I ended up getting
C# for Experienced Programmer's by Deitel&Deitel. It's basically the as the "how to program in c#", plus extra chapters for somebody who already has a little experience.

OK, I'll check that one too.
Thank you all for your replies.

Yep, I'm sure I'll buy this one. Everybody recommended this book, however this isn't a 'first book on the language' option.
Thank You.

Deliveries to Israel are expensive with commercial companies/web sites . There are some good online stores here too.
Thanks.

The best book for learning C# is Inside C# by Tom Archer, MSPress. Tom only uses Console apps, and he goes very in depth on almost everything you could ever want to know about C#. He even compares it to Java occasionally.

Just to let you know - I ordered "Inside C# by Tom Archer" and "Professional C#". I'm sure I'll use MSDN...
Thank you all for your advice.

Thanks for the update....I was kind of curious to know what book(s) you would go with.

Hi there,
I want to split up my app into a GUI part and the some "working" parts behind.
Which means to access certain parts of the GUI (e.g. Listbox) and fill it with data generated in nother methods of other classes.
For me as a newbie i could maybe imagine some ways to do it, but what's the professional approach on that one? Are there any tutorials around related to that?
thanks a lot in advance,
stonee

Yes, there are many avenues for breaking the GUI up and having business and/or data logic.
In .NET it is so easy to use libraries (DLLs) that makes a long term (old fuddy duddy) like me, have to rethink my old logic. Now that working with modules are so easy, it calls out for a greater object oriented design. It is what COM was supposed to be with all the hassle.
You can find many different articles right here on CP or go to msdn.microsoft.com and search for "n-tier". There are many things on their about breaking an application up into modules (tiers).
By using a modular approch to your application, you can replace you business logic without having to redistribute you GUI, or switch database sources without having to modify your business logic or GUI.
To even add more of a reason, with .NET, remoting and web services offer even more bang for seperation. If it is modular from the start you might remote out your business logic and data logic to reside out on a server or distribute it amongst different machines. Really easy to do with .NET. Flexible!
Of course, all this only matters if you application is something more than a simple one screen program to display some data. It really all depends on the type of application.

Ok, thanks for that.
But just for my understanding;
I have a method in class a, providing a certain information.
internal void OnAnswer(object myobject) <br />
{<br />
myobject.message<br />
}
and my main class
public class Form1 : System.Windows.Forms.Form<br />
{<br />
<br />
private System.Windows.Forms.ListBox listBox1;<br />
}
what's the best approach to add myobject.message to my listbox?
and what's the easiest one?
thanks again,
stonee
