Change color of one line

Is it possible to make the forecolor of a textbox a different color for each line?

I am working on an extensive chat program that has many different interfaces. One interface is a DOS interface, but I want the user to be able to distinguish which lines of text are his and which are his contacts' (I don't want to use a username in this interface). I want to make it so that your lines are blue and the other user's lines are red, is that possible?

Thanks!

All of the text in the TextBox control shares the same ForeColor property.

There is a control called the Rich Text Control that is a multiline text control that supports making texts in multiple colors.

Here are some places on the forum that talk about this control:
