Passing a RTB as a Paramater

I have a Function in a module called Functions

The function is:

VB Code:

Public Sub AddChat(ByRef RichTextBox As System.Windows.Forms.RichTextBox, ByVal ParamArray Text() As Object)        With RichTextBox
            .SelectionStart = 99999999
            .SelectionLength = 0
            .SelectionColor = Color.White
            .SelectedText = "[" & TimeOfDay & "] "
            .SelectionLength = 0
        End With
        For I As Byte = LBound(Text) To UBound(Text) Step 2
            With RichTextBox
                .SelectionStart = 99999999
                .SelectionLength = 0
                .SelectionColor = Text(I)
                .SelectedText = Text(I + 1) & Microsoft.VisualBasic.Left(vbCrLf, -2 * CLng((I + 1) = UBound(Text)))
                .SelectionStart = 99999999
            End With
        Next
    End Function

When i try and use this procedure, i can't reference my Rich Text Box

This is where i call it:

VB Code:

Public Function Connect(ByVal server As String, ByVal port As Integer) As Boolean
        Dim hostEntry As IPHostEntry = Nothing
 
        hostEntry = Dns.Resolve(server)
 
        Dim address As IPAddress
 
        For Each address In hostEntry.AddressList
            Dim endPoint As New IPEndPoint(address, port)
            Dim tempSocket As New Socket(endPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp)
            Try
                tempSocket.Connect(endPoint)
            Catch Err As SocketException
                AddChat(rtbChat, Color.Red, "Error #: " & Err.ErrorCode & ", " & Err.Message)
            End Try
            If tempSocket.Connected Then
                Socket = tempSocket
                MsgBox("Connected")
                Exit For
            End If
        Next address
        Return True
    End Function

RichTextBox is underlined in blue, with the error "Name 'rtbChat' is not declared.

Why do i get this? Any help would be GREATLY apreciated

P.S. Are my functions ok?

try passing the richtextbox ' ByRef ' not ByVal , eg:

VB Code:

Public Function AddChat([COLOR=Red]ByRef[/COLOR] RichTextBox As System.Windows.Forms.RichTextBox, ByVal ParamArray Text() As Object) As Object

yeah, i already tried that. STill nothing

The function works if you use it in the Class frmMain

But i can't seem to Reference the RTB of frmMain when calling it in a different class.

you need to pass a reference to your main form ( the form with the Richtextbox ) to your other class when creating it , eg:

VB Code:

'/// The Class
Public Class Class1
 
    Private frm1 As Form1
 
    Public Sub New(ByVal frm As Form)
        frm1 = DirectCast(frm, Form1)
    End Sub
 
    Public Sub test(ByVal s As String)
        '/// put the string ' s ' in to Form1's Richtextbox
        frm1.RichTextBox1.AppendText(s)
    End Sub
End Class

to use ( As a Test in this case ) ...

VB Code:

'/// the Form that holds the richtextbox 
    Private cls As Class1
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        cls = New Class1(Me) '/// Me being this form
        cls.test("some text")
    End Sub

You are GOD
