Hi,
I found this on George Shepherd's Windows Forms FAQ.
FAQ:
http://www.syncfusion.com/FAQ/Winforms/
Article link
45.2 How can I read and write zip files in my Windows Forms program.
Check out 'The Zip/GZip Implementation For .NET' available here. This library is released under a special GPL. Check out the above page for details.

There is a managed version of zlib available on the icsharpcode site.
J# will also provide libraries for porting Java 1.2 to .NET in that is the compression libraries that Java 1.2 had.

I meet such a situation that there is hundreds of classes in a big namespace, and i just want to borrow something from it.
i write something like this:
=====================================
namespace big
{
class apple;
class banana;
...
}
=====================================
namespace small
{
class apple: big.apple
{
}
}
=====================================
But i hope not to use inherit. is there any way to declare a alias or mapping?

If you mean, give a new name to an existing object; then yes you can do that.
using apple = big.apple;
This only works on a file by file basis though.

Thank you.
But what i exactly want is something like the cpp's #define.
#define small.apple big.apple
And pick the defines in a single header file, then it will only expose small part of a big library to user.
BTW, when i transfer my former cpp code to C#, i find it difficult to do with the #define macro.
for example
#define AT_LEAST(A,B) ...
here A B can be int, float, or double (surely template is another choice).
But in C#, #define can only define a symbol served for selected compile.
any suggestion?

Nope, for that you'll have to create empty wrappers as you had mentioned in the first post.

This is because #define's aren't type safe, and .NET is extremely type-safe; which is why they took out the ability to use macros in code. In most cases whenever you used a macro you should use a function instead.

I've been trying to find a way to interact with the Windows OS natively in C# (for both windows and web forms), particularly adding/deleting/monitoring/displaying tasks in the Task Scheduler.
Can anyone help me find some info on this?

Hello
Has anyone experienced problem with the Socket class ??
That is when I'm sending async data then when I have sent more than 2200 bytes then the socket will never close correctly even if I do
m_sock.Shutdown(SocketShutdown.Both);
m_sock.Close();
That is the .NET will think it closed but the server on the other end will never see that it closed. (Yes the server is working correctly, and detects closing from C++ and old VB)
I have downloading working fine with the .NET socket. But always when uploading then the closing procedure wont work when total bytes sent are greater than 2200 bytes, and it does not seem to mater if I send it all at once or in parts.
So the question here is if anyone else has this problem, and if this is a known issue ?

Are you using a Beta or RC of (VS).NET?
There was a known bug in the Betas/RC where the Socket.Close function didn't close the socket. If you want the full details search the DOTNET archives.
With it being such a large bug I would assume that it has been fixed in the final versions.

do it in your link.

I suggest at least skimming the HTML 4.1 Specification for a better understanding.

I wanna declare class with multiple inheritance .
public class myclass: System.class1 and System.Class2
How should I write the code that compiler accept it?

You can't, not directly anyway.
You are limited to one base class, but you can implement as many interfaces as you desire.
The recommended way is to have class1 and class2 be interfaces (or just one of them be an interface). The downside is that it makes it more difficult to extend existing functionality because you have to reimplement everything.
I suppose one solution would be to have interfaces IClass1 and IClass2 then create your classes Class1 which implements IClass1 and Class2 which implements IClass2.
Then your class that "inherits" from Class1 and Class2 implements both interfaces, relegating the method calls back to Class1 and Class2 objects if the base functionality is desired. And since you implement both interfaces you can cast the object to both interfaces as well.
Its not pretty but it should work for the most part.

So you can not do something like this?
<br />
class myClass:Class1<br />
{<br />
<br />
}<br />
<br />
class Class1:Class2<br />
{<br />
<br />
}<br />

Of sourse you can - that's single inheritance.
But you can't do:
<br />
class myClass: Class1, Class2<br />
{<br />
}<br />
The "solution" is to do the following:
<br />
class Class1<br />
{<br />
void foo(){};<br />
}<br />
<br />
interface IClass2<br />
{<br />
void bar();<br />
}<br />
<br />
class Class2: IClass2<br />
{<br />
void bar(){};<br />
}<br />
<br />
class MyClass: Class1, IClass2<br />
{<br />
Class2 m_implClass2 = new Class2;<br />
<br />
void bar()<br />
{<br />
m_implClass2.bar();<br />
}<br />
}<br />
<br />
Hope this helps!

This you can do.
I'm not really sure what this is called (baring a mini-object model).
I understand multiple inheritance as:
<br />
class mybase1<br />
{<br />
}<br />
class mybase2<br />
{<br />
}<br />
class mysuper:mybase1,mybase2<br />
{<br />
}<br />
<br />
Which you can't do in C#.
Cheers,
Simon
