Re: TcpListener.AcceptTcpClient query

30-Jun-02 21:32

TcpListener.AcceptTcpClient is a blocking call. How do I elegantly stop the call? From another thread say I want to stop listening. If I call TcpListener.Stop on the TcpListener object I get an exception. Some funny exception about how I halted a blocking operation. Right now I am putting an empty try{}...catch{} block and evading this exception. But there must be a more elegant solution! Any help is hugely appreciated!

Warm regards

Untested; but give this a shot. Instead of calling AcceptTcpClient() from the start; make calls to Pending() instead, and when it returns true THEN make the call to AcceptTcpClient.

Since that probably sounds convoluted, here's some code to illustrate it Smile | :)

TcpListener tcpL = ....;
 
tcpL.Start();
 
while(bShouldAcceptConnections)
{
  if( tcpL.Pending() )
  {
    TcpClient tcpC = tcpL.AcceptTcpClient();
    // do something with it
  }
 
  // Other processing that will eventually set
  // bShouldAcceptConnections to false
}
 
tcpL.Stop();

HTH,

I see. I was confused because the first post was by Mao. The second was anonymous and I wasn't sure about Mao posting anonymously.

System::Timers::Timer

Has anyone been able to use a System::Timers::Timer object in their Managed C++ code?

I can't get it to be recognized by the compiler, yet the help documentation indicates it is a .NET class and there is C++ support for the types.

Can anyone point me to a header file to include or some example code somewhere.

Thanks
Jim

You need #using <system.dll>

No that is not it. I tried that first. If you put in a
#using System::Timers ;
statement you get an "error C006 '#using' : expected a filename, found 'identifier'

Thanks though.

You cannot do that. System::Timers is a namespace name. You need to use using namespace System::Timers;

That's wrong usage.
Try this :-

#using <system.dll>

If Rama's understanding of your problem is correct you have a compiler error. If so, put this on top as he has suggested :-

#using <system.dll>

I didn't know that. I think what you have done would translate to the same thing in C#. Wouldn't it? But why is that important.

Yes you can. It's called a vector of vectors. Someone told me you can use STL in MC++ if you don't care about interop.

Well, I dunno to what degree they can interexist. Obviously you'd have no interop, but I see no point in interop unless you have a language that is actually vastly different to C++ to interop with.

And either way I thought it was worth pointing out that jagged arrays are not a new idea.
