Sockets Broken ??

3-Apr-02 5:28

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 ?

How to pass values from left frame to right?

3-Apr-02 21:42

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.

I have framed Web form, I want to pass parameter (query string) from left frame to right, so in the right frame it will show the records according to whatever user selected from left frame. How can I accomplish this? Confused | :confused:

do it in your link.

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

multiple inheritance

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? Confused | :confused:

<br />

}<br />
<br />
class Class1:Class2<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 />
// lots of public keywords missing!<br />

Hope this helps! Smile | :)

Progress control in status bar

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

Can someone give me the basic steps to getting this going? I have a lump of code which takes a while to execute so I want to temporarily put a progress bar into the status bar while this is happening then remove it when the code has finished.

The docs mention using ownerdraw status bar panels, but I need a bit more detail on exactly how.

Yes! Solution to compile MANIFEST resource into EXE ;)

This may not be exactly what you are looking for as it is done in VC++, however the topic matches exactly. Chris has written an article already titled: Showing progress bar in a status bar pane

At last I found the way to compile manifest into C# exe file. Download program called PE Explorer (http://www.heaventools.com). This program can insert manifest resource into the final exe file. It's a little odd, but it works very well Poke tongue | ;-P

Not with the current set of .NET controls. Its easy after you figure out how to get the parent to draw itself on a Graphics object you give it, but so far I've hit a dead end there.

You should really consider just using a custom control, CP even has an article available:

This should lead you in the right direction. Smile | :)
