Hello, I am working on a messenger which has some chat rooms now the problem is when someone enters/leave a room it show in blue that user has entered/left but after a while when someone else enter/leave all the old textformatting comes to defualt (black) here is my code:


Public Sub AddStatusMessage(RTB As Object, _
    ByVal Color As Long, Message As String)
    If Not TypeOf RTB Is RichTextBox Then Exit Sub
   
    With RTB
        .SelStart = Len(.Text)
        .SelFontName = "Tahoma"
        .SelFontSize = 9
        .SelBold = False
        .SelItalic = False
        .SelUnderline = False
        .SelColor = Color
        .SelText = Message & vbCrLf
    End With
End Sub

IT works quite fine but how to remain other colors

The code you have posted looks fine.

The symptom of losing all previous formatting and everything going to black is usually caused by setting the Text() property:

    RTB.Text = RTB.Text & "new message" & vbCrLf ' <---- this is wrong way to go about it

Do you have any other code that deals with the RichTextBox?...and if so, does it directly assign the Text() Property like above?

Therein lies the problem:

    txtChat.text = txtChat.text & themsg & vbcrlf

That will ERASE the previous formatting in the RTB.  You need to use code just like in your AddStatusMessage() method if you want to add something to the end without destroying all of your formatting.  =)

To pick your own color, use the RGB() function:
http://msdn.microsoft.com/en-us/library/zc1dyw8b(VS.80).aspx

So it would be something like:

    Dim myColor As Long
    myColor = RGB(255, 192, 203)
