hi all,
i am trying to make a chat program, when a client send a message it will first send the message to the server then server will send to target machine , i have found examples but all of them sending message just between server and client is there anybody who has source code ore article about messaging between clients through the server?
shoul i send target ip with the message which i send to server ? i mean i will send message+targetip to server in a socket and server will open the socket and get the target ip address after then server will create new socket and send to target machine i am so confused
thanks to everyone who send message and not

Hello sa_keles,
Do not confused. it is not a difficult subject. you just create one structure that define as like this.
struct msgPkt
{
char[] sender = new char[10];
char[] recerver = new char[10];
char[] msg = new char[100];
}
when any one login it will register there current IP address so no to give every time IP with every msgs. just give sender & reciever names.
Here i specified all field as char array becoz in network operation it is better that bytes of all field are fix & known size.
And if you use UDP insted of TCP then it is best for this.

i need print only numbers after comma
example
double x=33.452
Console.WriteLine(x);
output
452
how I do this ?
|
|
|
|

Heres a simple way:
static void Main(string[] args)
{
double x = 33.452;
string number = x.ToString();
char[] sperator = { '.' };
string[] seperate = number.Split(sperator);
double xSplit = Convert.ToDouble(seperate[1]);
Console.WriteLine(xSplit);
}
That will output 452 to the console. There might be an easier way though I'm not sure.
Hope that helps

Probably and eaiser way...But
this works.
double d = 3.14;
string s = d.ToString();
char[] delimiter = { '.' };
string[] a = s.Split(delimiter);
Console.WriteLine(a[1]);

Unfortunately the other solutions will fail under other cultures. Do the following instead:
double x = 33.452;
Console.WriteLine(x % Math.Floor(x));
|
|
|
|
|
This works for any culture. It also handles the case where there is no fractional digits, instead of causing an exception.
double x = 33.452;
string number = x.ToString(CultureInfo.InvariantCulture);
int pos = number.IndexOf('.');
if (pos == -1) {
Controle.WriteLine();
} else {
Console.WriteLine(number.Substring(pos + 1));
}

I've got an app as described in the subject. I am trying to write an update class that will handle changes to the database structure. I can figure out how to create a new tables using "CREATE TABLE" statements with the ODBCCommand object. What I cannot figure out is how to set field properties. Anything other than the basic (fld_name fld_type,...) statements result in an "[Error 42000] Syntax error in CREATE TABLE statement".
Mostly what I'd like to be able to do is set default values and create auto-number fields. If anyone can give me a bit of guidance on this or direct me to a useful link, I'd greatly appreciate it.
TIA,
Eric

How would I go about finding the free space on a given disk?
Thanks for any help.

check out 'DriveInfo class' in
the help menu. The sample seems
to be what you need.

Hi,
I'd like to make a listbox display multilines to user without using scrolldown when another event is clicked. And the same listbox shows only one item when another event is clicked.
Ex: when you click a button A, then a listbox B shows multilines of items.
And when you click the button A again, the listbox B shows only one line.
Thanks.
Kyah

Do you prefer any address about this algorithm or do you have any source code about them.
Thank you.

Are you trying to simulate multitask scheduling, or are you trying to apply these concepts to real task queue processing?
