DOT NET Developing Components:

Developing Controls: The vital fact about a control is that it has a visual element, but the visual representation of a class derived from Control is not allowed by the Windows Forms designer. Instead it shows the schematic representation of the components that the control uses while dragging from the Server Explorer or Toolbox window.
Resources and Internationalization: .NET and Win32 support a different model of resources. In Win32, resources are held in a section that is part of the portable executable (PE) file format and the resources are inlaid within this segment. But in the case of.NET, resources are part of an assembly, but they can be inlaid within the assembly or supplied as separate files.
Resources and .NET .NET has been designed with internationalization in mind. For example, let us consider of an application that has been downloaded from a trusted Web site and the Web site is in a locale different from yours. There are various applications that are created in their own locale. If the language is different from yours, it is obvious that the application has been localized to your locale and that the Web site gives you the option of downloading different localized versions. This scheme is typically used by Win32 applications.
