Multiple Users in Chat Server

anyone????

If you post code that is too long, many won't read it and will therefore not reply. Try posting just the important bits...asking people to debug entire programs usually results in no response.. :)

Good luck!

Oh sorry...actually I just wanted to know what the code was to add multiple users....i just put my code in so ppl would know what kind of server it was...

thanks anyway

Hi, I made chat server/client program.

I would like to know how to get multiple users to chat at once in the program. So far the last user to connect, get's the message not everyone.

I'm posting the whole code for the chat server.

PS: I got my program to run in the system tray

Dunno how this will show up...

// Code starts here
Dim num As Integer
Dim intMax As Integer


Private Sub cmdSend_Click()
Winsock(intMax).SendData (txtSend.Text + vbNewLine)
txtSend.Text = ""
End Sub

Private Sub Form_Load()
Dim counter As Integer
' this code is to show the form in the system tray
'the form must be fully visible before calling Shell_NotifyIcon
Me.Show
Me.Refresh
With nid
.cbSize = Len(nid)
.hwnd = Me.hwnd
.uId = vbNull
.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
.uCallBackMessage = WM_MOUSEMOVE
.hIcon = Me.Icon
.szTip = "mAdD CHAT SERVER" & vbNullChar
End With
Shell_NotifyIcon NIM_ADD, nid

' Set the LocalPort property to an integer.
' Then invoke the Listen method.
intMax = 0
Winsock(0).LocalPort = 1001
Winsock(0).Listen


End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
'this procedure receives the callbacks from the System Tray icon.
Dim Result As Long
Dim msg As Long
'the value of X will vary depending upon the scalemode setting
If Me.ScaleMode = vbPixels Then
msg = X
Else
msg = X / Screen.TwipsPerPixelX
End If
Select Case msg
Case WM_LBUTTONUP '514 restore form window
Me.WindowState = vbNormal
Result = SetForegroundWindow(Me.hwnd)
Me.Show
Case WM_LBUTTONDBLCLK '515 restore form window
Me.WindowState = vbNormal
Result = SetForegroundWindow(Me.hwnd)
Me.Show
' if button is clicked then show popUp menu
Case WM_RBUTTONUP '517 display popup menu
Result = SetForegroundWindow(Me.hwnd)
Me.PopupMenu Me.mPopUpSys
End Select
End Sub


Private Sub Winsock_ConnectionRequest(Index As Integer, ByVal requestID As Long)
Dim counter As Integer
Dim num As Integer

If Index = 0 Then
intMax = intMax + 1
Load Winsock(intMax)
Winsock(intMax).LocalPort = 0
Winsock(intMax).Accept requestID
End If

End Sub
Private Sub Form_Resize()
'this is necessary to assure that the minimized window is hidden
If Me.WindowState = vbMinimized Then Me.Hide
End Sub
Private Sub mPopExit_Click()
'called when user clicks the popup menu Exit command
Unload Me
End Sub
Private Sub mPopRestore_Click()
'called when the user clicks the popup menu Restore command
Me.WindowState = vbNormal
Result = SetForegroundWindow(Me.hwnd)
Me.Show
End Sub

Private Sub Form_Unload(Cancel As Integer)
'this removes the icon from the system tray
Shell_NotifyIcon NIM_DELETE, nid
End Sub

Private Sub Winsock_DataArrival(Index As Integer, ByVal bytesTotal As Long)
Dim remIP As String
Dim counter As Integer

remIP = Winsock(Index).RemoteHostIP

' Declare a variable for the incoming data.
' Invoke the GetData method and set the Text
' property of a TextBox named txtOutput to
' the data.
Dim strData As String
For counter = 0 To num
Winsock(Index).GetData strData
txtOut.Text = txtOut.Text + remIP + " : " + strData
txtOut.Refresh
Next
End Sub
