Hi, i'm new here and this will be my first question. I have seen this asked on many forums and it seems know one can come up with a solution, yet i know it's possible because it's available to buy as a control library from SickWin. I liked the look of it and attempted to replicate the effect, but without luck. Now it's become a mission for me!!! I have done much with the textbox control, even managed to create one that can support transparent backcolors, however i can't work out how i could change it's shape. To start with all i want to be able to do is give it round corners. Sounds simple, but it turns out the .net textbox is just a thin wrapper around the old win32 textbox and is not easily customizable. So has anyone implemented this before, and if so would they be kind enough to point me in the right direction.
