access level

In VB code, the ability of other code to access it (that is, read it or write to it). The access level is determined both by how you declare the code and by the access level of the container of the code. If code can't access a containing element, then it can't access any of its contained elements either, no matter how they're declared.

File Extension / File Type

In Windows, DOS and some other operating systems, one or several letters at the end of a filename. Filename extensions follow a period (dot) and indicate the type of file. For example, 'this.txt' is a plain text file, 'that.htm' or 'that.html' indicates that the file is a web page. The Windows operating system stores this association information in the Windows Registry and it can be changed using the 'File Types' dialog window provided by Windows Explorer.
