File Handling for Visual Basic 6.0 Users
Visual Basic 2008 expands file-handling capabilities while providing compatibility with previous versions of Visual Basic file I/O functions.
Visual Basic 6.0
In Visual Basic 6.0, file handling is accomplished using various file I/O functions such as Open, Input, Output, and Append. The FileSystemObject object provides an object-oriented method of working with files.
Visual Basic 2008
In Visual Basic 2008, file handling is accomplished through the My.Computer.FileSystem Object. In addition, the System.IO.File class includes functions that provide compatibility with the older Visual Basic file I/O functions.
The FileStream class provides access to standard input and output files and error devices.
The following table lists members of the My.Computer.FileSystem object available in Visual Basic 2008.
