Create customize OpenFileDialogBox and SaveFileDialogBox using shell

The Open dialog box lets the user specify the drive, directory, and the name of a file or set of files to open.

The Save As dialog box lets the user specify the drive, directory, and name of a file to save.

Explorer-style Open and Save As dialog boxes provide user-interface features that are similar to the Microsoft Windows Explorer. However, the system continues to support old-style Open and Save As dialog boxes for applications that must be consistent with the old-style user interface.

In addition to the difference in appearance, the Explorer-style and old-style dialog boxes differ in their use of custom templates and hook procedures for customizing the dialog boxes. However, the Explorer-style and old-style dialog boxes have the same behavior for most basic operations, such as specifying a file name filter, validating the user's input, and getting the file name specified by the user. For more information about the Explorer-style and old-style dialog boxes, Check out in the given images.
