newbie question

[laclac01]

If i have a text box and i print data in that text box and then i want to print data underneath that so i get a log of my message how can i do that?
I have tried this code
txtDebug.Text = txtDebug.Text & "Message Sent" & vbCrLf & vbCrLf

But it just seems to print a "black thingy" some indescribable character after message sent and then it prints the new data on the same line

I have looked on line and it seems that this is how everyone is doing it? Is there something i have to set my textbox to?
I am using vb6.0
thanks

Set the Multiline property of the TextBox to True.
