socket or remoting whichever be the case,but why is that TCP faster than HTTP

When sending over TCP you don't have to do much other than serialize the objects and chuck them over the connection.

Using HTTP you have to use the HTTP protocol which takes more time and bandwidth.

You also have the choice of the Binary Serialization and SOAP serialization. Binary makes the smallest output but SOAP is better for interop with other system or if you need the output to be human redable.

In the end you need to choose which is the right combination for you based on what you need. If you need built in security and authentication then HTTP remoting via IIS is best, it also works well with firewalls. If your just working on an intranet or you really need the performance TCP will be fine.

Depending if you are on the local machine, you can even use IPC, which is alot faster than TCP or HTTP.

Hi all

does anyone have a working example (2.0) of how to use the registerhotkey API for c#

i am trying to run an event even if the window is not in focus and I have seen a few crapy vb.net examples that i can get to compile

I was wondering if there was a C# example floating around since thats what i prefer to program in anyway.

(also yes I am google-ing as we speak im just useing the forums as a backup)

Thanks

Hi,
How do you copy a picture box during run-time??
ps. I'm intending to make a copy of it and put it in the same form/panal during run time;

Hello Muammar,

In think what you are searching for is "Clone"ing.

the following code is in C#

I have 2 interfaces

public interface Interface1
{
string ReturnString1();
}
public interface Interface2
{
string ReturnString1();
}

now i implement both the interfaces in a single class

Class A:Interface1,Interface2
{
}

now according to my searchings i found that we can implement both the interfaces in the following manner

Class A:Interface1,Interface2
{
public string Interface1.ReturnString1()
{
return "Interface1.ReturnString1";
}
public string Interface2.ReturnString1()
{
return "Interface2.ReturnString1";
}
}

but on compiling it is giving an error:"the modifier public is not valid for this item"

after i remove public and then i compile the code, it compiles successfully
but i'm not able to access these methods by creating an object of the class.

Can anyone solve this problem

the default access for any method or property is private. If you remove 'public' then they default to private right through your code.

The default access for a method is public ... "but" ... when explicitly implimenting an interface method it is automatically public and you cannot put any modifier on it, even the public one.

Its correct that modifier public is not valid for those function.

Also pls make sure you are accessing those function from a object type of Interface1 or Interface2 and not from a object of the class A directly, to get the access to those function.

i.e.

Interface1 interface1 = new A();

interface1.ReturnString1(); //Here you will be able to access the function.

All the code is in C#,
so if i dont specify access modifier then by default it is public
after implementing the methods in an interface we can access the methods thru that class's object.why can't we do the same with this.

See the function name in the class A is as Interface1.ReturnString1(), and thats why you can not a.ReturnString1(). But the function name for the Interface1 is "ReturnString1" and you can call it using object of type Interface1.

can u give me a code snippet about how actually u implement it

Manoj Kumar Rai5-Jun-07 21:27

5-Jun-07 21:27

I wrote you code in the previous replies it self.

In your case:

A aa = new A();

//Cast it to interface
Interface1 interface1 = aa;

//Now u can call the Function ReturnString1

interface1.ReturnString1();

Also you can write it as:

((Interface1)aa).ReturnString1();
