I found it, there is a get/set property in Environment class.
Environment.CurrentDirectory

I have a xml file and datalist,I put label on datalist and I want to bind it to xml file.
The definition of xml is something like this:
<?xml version="1.0" ?>
- <Something xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Title>MFC</Title>
<Title>Button</Title>
<Title>RichEdit</Title>
<Title>EditBox</Title>
<Title>ComboBox</Title>
</Something>
I want to bind Title to labels of datalist I don't know how to do it,is that correct:
Read the xml file with xmlreader then bind a table to data list?If it is correct I don't know
one thing about databining:
DataBinder.Eval(Container,?????-->what should be here?)
thanx

I need to get ahold of C# functions such as pow, abs, etc. min and max would also be nice. Do they exist ? Where ?

Got it. I typed System.Math and intellisense did not find it, so I assumed it did not exist. I need to get Visual Assist on here, pronto.

I know, thanks, I just had not reinstalled it just yet after all the hassles I had getting .NET installed at all.
Intellisense is working, Matk is a class. How gay - I have to type Math.Min when I want to min something ? I suppose I could type Math m; m.Min, but it still sucks.
C# is pretty cool though, but I need to do some testing. I am convering an image library I wrote using GDI+ in C++ and I think initially it is orders of magnitude slower doing exactly the same thing as the C++ code I wrote prior.

Funny how I lile the fact that I have to type in the class name first and then it's method to use it, while you think it is naff. I guess I like the structure of it, it helps to structure the app in my head better than if all I had to type was Min.
Just FYI, and you probably do know this, you can instead of doing Math m do using m = System.Math;. Has much the same affect, but it is across your whole class, not just a procedure.
And the old way would be to just wrap it in a normal function called Min of course 
I must say .NET is the first system that I have really started to understand the underlying structure of. VB I just cruised along and did not really care much whether something was an object, class, blahdingaling or whatsamacallit. But with .NET the whole framework of classes and namespaces really just works for me. I certainly now see the advantage of understanding the underlying strutcute when it comes to developing

I dunno what VB offers, but in C++, math is a library which provides these functions, so I am just used to the language offering maths facilities without the need for my code to be full of Math.

Yes, I realise that, thanks. It gives me the overhead of creating a class and still looks ugly.

As a C++ programmer, the old way is to wrap it in a macro, so it occurs in place. I am writing image processing code, as you will see when Chris posts the first article. Is there a way to inline code in C#, do you know ? Image processing is an area where every clock cycle counts.
Paul Watson wrote:

I suspect based on what I hear that VB.NET is structed a lot better than prior versions, so it's no wonder that it's now making such things clear to you. ON the other hand, I feel C# is hiding too much from me, but I can certainly see how that is helping me develop this thing faster than I would in C++, which is a *good* thing. But it is a ton slower to process the same image as the equivelant C++ code, and I dunno how much of that is ways I cannot optimise code compared to the C++ version, and how much is the CLR.

Actually - as a C++ programmer, you would wrap it in an inline function.

Not if I was doing image processing. I hate macros, but the inline keyword is a suggestion which the compiler is free to ignore, so a macro is the best way of knowing for sure the code is running in place.

I havent really tried C# much, and have been using VB.NET with no IntelliSense problems. Does it not work as well is C#? What is "Visual Assist"?
Oh, in VB.NET, if I type "system.math" it automatically changes it to "System.Math". does this happen in C#?

www.wholetomato.com - it has a 30 day trial, try it for yourself. It does a LOT more than just intellisense. But for intellisense, how about being able to specify the scope from which you want to see options, if you want to see public, protected or private items, if you want to see functions, or variables, or enums. In any combination.
VA does the case correction, C# does not by itself.

Thats the impression I got. I must say, it strikes me as silly that that is the case however. It means that whatever is doing the case correction is not built into the editor, but actually into the bit that each language provides to plug-in to the editor. Or at least, so it would seem.
After being used to it in VB since 16-bit VB3, it certainly takes a bit of getting used to

Well, VB is not case sensitive, SomeClass and someclass is the same thing. In both C++ and C# SomeClass and someclass is two different classes because the languages are case sensitive. Because of that I think it would be *very* dificult to make C++ and C# correct the case for you.
I mean, if you have 2 int's called IntOne and intOne, and you just typed intone, which one should the IDE select?

This is a problem I have with VA at work - our class library includes try/catch wrappers which specify a HRESULT called hResult. Every time I type hResult, it turns it all to capitals, as it does not expand the macro and see the variable name.
If VB is not case sensitive ( and how gay is THAT ? ), then the IDE isn't doing any case correction at all, it's simply ignoring it - right ?

And the VB programmers proclaim that it is gay that C/C++ IS case-sensitive.
Until you get used to it, there doesn't seem to be any reason for case to matter; why would you want a variable named foo and Foo? Once you're used to it you quickly realize that (according to my style) foo is protected and Foo is public.
When I coded in VB since case matter I prefixed private members with _. A practice many C/C++ people have followed as well.

Okay, I know I will get flamed for this, but why prefix private members with anything? I dont expose variables publically, but use property methods that are public, so I never have public variables. As for private methods, why would you prefix them at all?

oops, guess I shouldn't be replying to messages after I wake up from sleeping on a long ride home.
I should have said private variables; because in many cases in my code a private variable would have a public get or get/set property defined for it.

ahhh yes... I use "m" as a prefix, so I know the variable is "mine".

I think vs.net behaves bit more nicely than the vstudio for intellisense. Its able to pickup most of the classes and variables.
But I've read somewhere(dont remember where i read) that VA is not so stable for vstudio.net, I guess the beta status explains that a bit.

Can someone tell me whats the sprintf equivalent in c#.
I want to format a string, an sql statement (insert into ...) based on some values.
thanks

There is nothing as evil as sprintf in C#, but a facility similar to ostringstream is StringBuilder.

String.Format it takes the same arguments that Console.WriteLine does which allows you to specify some formatting options similar to ?printf. Here is a link to the format string specification.
