Are you setting the BackStyle property to transparent?
I just tried it and it works fine (I put a picture behind it)

>I have a textbox that I want to be transparent. I go to properties and set the text box property from opaque to transparent, but when the form runs the text boxes are not transparent even though the setting is to transparent. It seems relatively simple to do, but it's a no go. Labels have been set to transparent and they work fine. So what have I forgotten?
