How can I make my Edit Controls created at runtime look 3D?

The trick is making sure that the control gets the WS_EX_CLIENTEDGE extended style. To do this, you can:

• Create the control using CEdit::CreateEx() instead of CEdit::Create(). Remember that WS_EX_CLIENTEDGE is an extended style, not a "normal" style, so you cannot specify it in the dwStyle parameter; you have to specify it in dwExStyle.
• Use CEdit::ModifyStyleEx() to add the WS_EX_CLIENTEDGE
