Computing Projects in Visual Basic


en Limba Engleză Paperback – 31 aug 2000
The book is divided into three Parts. Part One goes through all the main programming concepts carefully. These need to be understood by all students. Part Two covers a variety of topics which for some students will prove useful in their project work. These cover items such as designing menus, printing reports and interfacing with the Internet. Part Three goes through the main stages of producing a project to 'A' level standard by using a sample project based on a snooker club. All the programming concepts used in the sample project are covered earlier in the book. The approach throughout is a very practical one. Running throughout Parts One and Two are 47 programs, with step-by-step instructions explaining how to build them and explanations about how they work. In Part Three you are taken through each stage in the design and coding of the full project, again using a step-by-step approach for the coding.
