You use the wrong syntax!, the correct syntax is

protected override bool ProcessCmdKey(
	ref Message m,
	Keys keyData
)

Try this:

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == Keys.F5)
        {
            MessageBox.Show("F5 pressed!");
        }
        return base.ProcessCmdKey(ref msg, keyData);
}

Hope this help.

By reading and understanding what the C++ application is doing then re-writing it in C#.

If it is managed C++ then you might be able to run the assemblies through Red Gate's Reflector to see what they produce as it could be a viable shortcut.

The C plus plus is similar with the C sharp. If this project is not too big, you can create a C sharp project, and then add these C++ files to this project, and comment codes in these files, and then modify format from c++ to C# format one class by one class.

Unless you are using Managed C++ (and even that is stretching things) this is utter rubbish.

C# may have been modelled on a mix of C++ and other languages but its resemblance is only passing. The main difference is that the framework is totally different. This means you have to find equivalents for things that look nothing alike and may operate in different ways.

For example, if you have an MFC application written in C++ using CView and CDocument classes then you will have to re-write those classes as C# has no direct equivalent. And what happens when you have a situation in C++ where there is a lot of low level memory manipulation? You can't do that easily in C#.

This is correct - for most of the C/C++ library and for low level memory manipulation you are better off starting from scratch.

However... for the rest there is a fairly logical process for conversion which can be implemented and is implemented in some source code converters.

So, if you strip out the C/C++ libraries and the low level memory manipulation, how much is left? Thinking about my old C++ projects, very little I'd reckon.

Not necessarily. Some apps have a lot of internal business logic that isn't library intensive and doesn't have any low level memory manipulation. And some library references which do have direct equivalents are used a lot (STL collections, Math, console IO, etc.).

Listening port for many number of clients

Hi,
I have a listening port and it should handle many number of clients at a time.

When i try with 10-25 clients in LAN, its work fine. My doubt is that will it be sucess when it upload to the web, where many number of users acess the server from diffrent part of the world.

Below code is used to listen as server. Please verify the code for multipe number of client, what will be the approximate limit of clients can connect?

strHostName = Dns.GetHostName();
IPHostEntry ipEntry = Dns.GetHostByName( strHostName );
aryLocalAddr = ipEntry.AddressList;

Socket s_listen = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);
s_listen.Bind(new IPEndPoint(aryLocalAddr[0], 400));
s_listen.Blocking = true;
s_listen.Listen(-1);
// Setup a callback to be notified of connection requests
s_listen.BeginAccept(new AsyncCallback(app.OnConnectRequest), s_listen);

-----
public void OnConnectRequest( IAsyncResult ar )
{
Socket lis = (Socket)ar.AsyncState;
NewCon( lis.EndAccept( ar ) );
lis.BeginAccept( new AsyncCallback( OnConnectRequest ), lis );
}

thankyou

Do you mean the internet? I'm being pedantic I know, but the web is just port 80 and 443.

I can't tell you the limit becuase you also need to take in to consideration the power of the server, what the service will actually be doing and so on. If it can't handle the number of clients, can it be scaled out across multiple servers?
