Introduction to Delphi Programming is designed for the student who wants to learn to develop Windows applications using the Delphi product from Inprise Corporation (formerly Borland).
This course introduces Delphi's integrated development environment. Applications are built using forms, components, and event-based programming in Delphi's Object Pascal programming language.
Object Pascal is presented in detail, so students will become familiar with the language's statements, declarations, data types, procedures, functions, and object-oriented features.
The course provides an extended example showing how to use Delphi's Visual Component Library to access information stored in a remote database. For students familiar with databases using the File Manager database management system developed by the Veterans Administration, this exercise works with a specialized set of client-server software known as the RPC Broker, also from the Veterans Administration.
The average amount of time to complete the on-line materials is 14 to 16 hours.
Upon successful conclusion of the course, the student should be able to:
Note: Students should come in with exposure to at least one programming language.
Students also must be able to configure and create a File Manager database file in order to perform the course's RPC Broker programming exercise. However, specific knowledge of M is not required for the RPC Broker exercise.
