Common Controls - IP Address

The four-part dotted-decimal IP editor is a common control you have to opt into: InitCommonControlsEx with ICC_INTERNET_CLASSES registers it, then you drop an IPAddress control into your dialog template. The dialog procedure here just reads the entered value back out as text when OK is pressed. Use it whenever you need validated IP input in a Win32 dialog without writing your own parsing and range checks.
