Yes, it will, try it.

Test your code, it will fail if you don't cast it, mine did, I previously wasn't casting it.

I can't see who it would work - it won't work on my computer...
"t" is a Control.
"t.Text" is not valid on a Control.
how does it compile?

no it does not:

Hi all, this is kind of an architecture question:
I'm in the initial stages of designing a commercial app that is ported from c++ to c# (rebuilt actually) and want to use business objects that can be used both remotely and locally (the old app was local only, this is a new thing). (I.E. a user may install in network server mode or single computer mode)
I'm very new to remoting, just getting my feet wet and am wondering in this situation how to go about this.
I don't want to duplicate any code if possible.
How would you suggest creating a business object that can both be remote or local without having to change the source code for the objects themselves?
(Possibly not inherit from MarshalByRefObject in the case of being local but do inherit from MarshalByRefObject in the case of being remote?)

Hi,
You should take a look at VB.NET Business Objects by Rocky Lhotka. (Yes, it's VB.NET, who cares, it's easy enough to convert to C#!)
All the info you need is there, plus you get the CSLA.NET framework for free! It has even been translated into C#...
Very good book! You'll love it!

Looks ideal, thanks!
Now if I hadn't just blown my book budget on those UML books...

Inheriting from MarshalByRefObject doesn't hurt anything if you're not using remoting. Heck, almost everything in the Windows Forms does! (those that inherit from Control, which inherits from Component, that inherits from MarshalByRefObject). It that way with any OO design and inheritance - only use what you want to. It's field values that take up space in memory - not a gazillion methods and properties. And such methods and properties won't do anything unless they're called. Heck, most of those controls aren't even remoting because they're not serializable (although you could either implement an ISerializationSurrogate for them, or extend them and mark your control as [Serializable]).
The best place to put such an object is in an assembly that both the client and server share, such as the one where the remoting interface is (assuming you're doing it that way, and you might as well since you are using a shared assembly now - it makes for easier maintainence rather than generating a new one using soapsuds.exe or something when you change your remoting object).

hello ,
Hello i design one software for graphics systems.
It consists of more graphical calculations like AutoCAD.
Which language i should use for that?
C++ with MFC or C# ?
I know Java will be the
worst for this kind of applications.
Can i expect performance of C# equal to C++ in my case?

For something like CAD, you would be using a graphics technology like OpenGL or DirectX to do the heavy work, so there wouldn't be much need to worry about what language it was written in.

Actuall Java3D is based on DirectX so it doesnt really matter. Obviously it would be the easiest with MFC so You designate a view, but you can do it in C# and use the frameowrk classes. But you wont get the speed and since its cad its not that intensive so either shouldnt matter

Should we wait for a C# with some better performance?

its more of a fact that your running managed code instead of c++ so the performance is still good. For cad drawings thats not rotating 3d rasterized images you wont even notice the speed difference.
I develop games in direct3d so I see it right away

Why would you want .NET?
For anything related to graphics and speed I personally would use C++ and maybe MFC. If I had a need for the .NET frameworks I would probably use MC++. Speed and C# (or VB.NET) does not go hand in hand. The speed is fine for business applications or data driven applications but graphic driven apps need a core C++ at this time.

C# is a managed language.
It means and seems that we should never wait for a c# with some better performance. Do you agree?

Startup times will get faster, but probably not a lot faster. Also, some BCL classes are slower than their C++ counterparts (but then, some BCL classes are faster than the C++ ones).

hello
my question is do .NET base class library functions
been written from scratch or do they call the underlying
Win32 API ?
Are Win32 API (classic) and .NET library two
entire different entities?

In most cases, no. The .NET BCL functions/classes usually use the Windows API underneath. However, the layer of abstraction they provide in many cases allows one to create implementations of the base classes for other OSes. For instance, the Mono project has created implementations of many BCL classes for Linux and Mac OSX.

Are you asking me why I made the quote be in small letters? I did that so that my sig wouldn't take up too much space.
