In its current inception, ASP does not directly provide any comparable objects to read files that contain binary data such as an Excel worksheet with macros, an Adobe Acrobat (.pdf) file, a .gif image, or any other files that contain binary data. However, an ASP developer can write a custom business object or component that adds this functionality.
