As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
In practice, the available CLASS words would be a list of less than two dozen terms. CLASS words, typically positioned on the right (suffix), served much the same purpose as Hungarian notation prefixes. The purpose of CLASS words, in addition to consistency, was to specify to the programmer the data type of a particular data field. Prior to the ...
Windows Forms, also known as Winforms, is a free, open-source graphical user interface (GUI) class library for building Windows desktop applications, included as a part of Microsoft.NET, .NET Framework or Mono, [2] providing a platform to write client applications for desktop, laptop, and tablet PCs.

A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner).
The class defines the window procedure used tp process messages for all windows created with that class. [1] The structure provides a template from which windows may be created by specifying a window's icons, menu, background color and a few other features. It also holds a pointer to a procedure that controls how the window behaves in response ...
