Alternative Managed API:

Instantiate a System.Windows.Forms.Form and set its properties to control its style.

The System.Windows.Forms.NativeWindow class can be used to encapsulate a window handle. It provides properties and methods that can be used to perform the same behavior as the CreateWindowEx method.
