how to have colored single border line for rich textbox and buttons in vb.net

For rich text开发者_StackOverflow社区box in vb.net i want to have single border line. Fixed single and Fixed 3D are having some dimensional effect which i do not want. And i would also like to change the color of the border.

And same thing with the button, for them how to have single line border and specified color.

According to the documentation, the richtextbox doesn't support FixedSingle, so it defaults to Fixed3D. You could put the RTB into a panel and set the RTBs border to none and the panel's border to fixed single.
