if i use
string [] str=new string[3];
int i=14;
int j=15;
array[0]=""+i+""+j;
then
array[0]=1415

is it possible in int[]?

I AM WORKING ON "PLOTTER ROBOT"(FYP).

Convert the two integers into strings, concatenate and assign.

You get the number if digits in j(it's easier to covert it to string and use the Length property)

private static string Add(int i, int j)
{
int result = (int)(i * (int)Math.Pow((double)10, (double)(j.ToString().Length)) + j);

return result.ToString();
}

Be carefull..this method returns the result as a string..as "adding" to integers might be bigger than Int32.MaxValue !

Socket Connection Fails

Hi,

I have a Client Server Application that communicates through
socket.
The Client is a VC++(6.0 version) and the Server is a C# application.
While trying to connect to the Socket from the VC++ application by entering the ip for example in - 012.220.200.001 - format I am unable to connect to the listening Socket. I get 10061 or 10049 exception.
But when I try to connect to the Socket server by entering the ip in the format 127.000.000.001(localhost), I am able to connect.

I want to connect to the Server by entering the ip address in either ways.

Please suggest.

Let me know if I will have to change the listen functionality which is currenty
Socket workerSocket = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp)

IPEndPoint ipLocal = new IPEndPoint (IPAddress.Any, port);
m_mainSocket.Bind( ipLocal );
m_mainSocket.Listen(4);
With Thanks and Regards,

Abraham Chethuvelil

Are you in a local network? ie. Connected to the internet through a router or similar?

Because if you are, and you enter your IP address, you are besically sending the request to the router, which has no idea what machine to pass it on to.
You'd have to set up some port forwarding to get it to work.

Hi!
I think the format of your IP address is screwed.
If you start it with '0' the numbers will be interpreted as octal.
I just tried a ping to "012.220.200.001" and ping told me that it actually tried to connect to 10.220.200.1!

Hi,
you can do this with below code..

<br />
int i = 1+2+3;<br />
TextBox1.Text = i.ToString();<br />

Hope it will help you.

Hi,
first of all what are you diong ? what you wanna do its yet not clear.

Member 3499052 wrote:
textbox.Text = 1+3+4+5+6

<br />
int i = 1+3+4+5+6; // you can calculate here<br />
textbox.Text =i.ToString(); // here you can convert i to string

Now

Member 3499052 wrote:
int i = Convert.ToInt32(TextBox1.Text);
Label1.Text = i.ToString();

No need for this,

Just write,

Label1.Text = TextBox1.Text;

He wants to write a calculator, where he can type into a textbox "1+2-3*4" and it does the calculating for him.

ie/ you've totally misunderstood the point!

You need an expression evaluator like this[^] one.

If you'd followed the link you'd have found a whole article about one. I'm curious as to why you voted me down for pointing you towards the answer.

Include a reference to his assembly in your project and then do the following:

ExpressionEval eval = new ExpressionEval(txtFunction.Text);
object output = eval.Evaluate();
if (output != null)
{
  // You have your answer. Do what you want with it.
}
