Hi there,
I am trying develope an internet chat application in C#.Net using Visual Studio 2005.
I am struggling succeeding in this and basically ended up creating a network chat app.
What i want to do is create an app that direct chats over the internet (like on a network chat). only my friend and myself will use it so no rooms or anything is needed its just a plain direct chat over the net.peer 2 peer like.
I know the using of sockets or remoting but everywhere i look it all just goes down to an tcp/ip chat.
Could anyone please help me with this or direct me somewhere where i can get help please?
Kind Regards
Deon

Im in a private network and my friend will be in a public network.
hmmmm i guess firewalls will be a problem ouch.
any suggestions maybe?
im so confused and i know this is not alot of code it only has to be the most simplest
app which sends text like p2p.
i have some code i you want to take a look at it and maybe direct me from there.
Thanks alot

If neither of you has a static ip then you'll need a web service to keep track of the ip-s for peer discovery, even if the app will be used by only the two of you.

You've got a full 101-key keyboard in front of you - use it. SMS-speak is frowned upon because it makes your posts hard to read.

You do know what TCP/IP means? it means Transmission Control Protocol over Internet Protocol. Which should give you a clue to how data is transmitted over the internet.

I've been to the database and retrieved 1 or more values from a table that match with values for my ListBox text. eg
1 = John
2 = Peter
3 = Fred
etc
I have values say, 1 and 3 in a dataSet and can view each row
I want to get back to my page and have 1 or more names (John and Fred) highlighted. It's fine if there is one but multiple?
Code so far :
for (int i=0;i < dataSet.Tables[0].Rows.Count; i++)
{
mylistbox.SelectedValue = dataSet.Tables[0].Rows[i]
"PersonID"].ToString();
}
This only highlights Fred, the last row in my listbox on my page.
Any advice would be great.

You can create a ListItem and set its Selected property to true. Or iterate throught
ListItems in your ListBox.
Something like this:
int i = 0
foreach(ListItem li in ListBox1.Items)
{
if( (li.Value == dataSet.Tables[0].Rows[i]["PersonID"].ToString())
{
li.Selected = true;
}
i += 1;
}
Sincerely,
Elina
Life is great!!!
Enjoy every moment of it!

Hi All,
I have a little problem...
From one form to another i am sending an array list.
ArrayList _line = new ArrayList();<br />
_line.Add(strNum);<br />
new frmCellNumberListCheck().Chekker(ref _line);
On the next form i have a list view. How do i populate the a list view with the values in my array list?
Here is the part on my next form...
public void Chekker(ref ArrayList _NewList)<br />
{<br />
_Confirmer = _NewList;<br />
this.ShowDialog();<br />
NewList = _Confirmer;<br />
}
Now in the load method of the form i want to use the _Confirmer to populate the listview called ChekkerList.
How do i go about doing so...
Thank you in advance
Nico

u can try
ListViewItem lst = new ListViewItem();
for(int i=0 ;i < _NewList.Count ;i++)
{
lst.subitems.add(_NewList[i].ToString());
}
CheckerList.items.add(lst);

Hello,
i am using a treeview so to assign different icons to different nodes i used a imagelist and assigning the imageindex and selected imageindex properties of the treenodes with the index of the imagelist icons collection. But for some nodes in the treeview that setting is not working its displaying the icon at the 0th index in the imagelist and whenever i display the index value associated with that node using a messagebox its giving "-1" value.
Why thats happening how can i get the icon which i assigned using imageindex and selectedindex to those nodes.
Please help me,
thanks in advance.

The way I read it you want to open a new Window..
form name: frmName
frmName frmName = new frmName();
frmName.Show();
If you didn't mean to open a form then I am misreading your post and am sorry

How to generate a random number.
I have Visual Studio 2003.
Help.
Vasildb

use the following code snippet:
Random rand=new Random();
and then u can use
rand.Next(1,100);
to generate a random no. between 1 & 100
Basically u have to specify the limits in which u want to generate a random no.
Hope this will work.

That will generate a random number between 1 and 99.
