Indicates how to open a file when calling file-access functions.
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
When you call file access-related functions, you can use enumeration members in your code in place of the actual values.
The OpenAccess enumeration defines constants used to identify whether a file can be read from (Read), written to (Write), or both (ReadWrite). A file opened for Read access cannot be modified, only read from. The following table lists the OpenAccess enumeration members.
When performing file I/O operations, the My.Computer.FileSystem object provides greater performance and ease of use than legacy file I/O methods. For more information, see FileSystem object.
