Hi -- I've been having real difficulty understanding OLE. I've printed out the description in the AB Users Manual and read it over and over many times. I'm afraid it is just too brief, and assumes a level of programming experience which I do not have (Although I have over 20 years experience with the 'C' programming language, I do not have any experience with object oriented languages, other than AB's CBT).
I've looked through the AB online library and AB Yahoo files, with little success. I believe that my biggest problem was that many terms are used without any description as to their meaning. For example, many of the following can be easily confused with terms used in every day language. Terms such as Methods, Properties, As Date, As Single, As Long, Variant, Sub, Type, As Object, As Boolean, and As Integer appear to be borrowed from other programming languages. In 'C' the terms Long, Short, and Int define integers. And each may or may not contain a different number of bits, depending on the computer or operating system used. But what do those words mean in AB's OLE? Are they all integers? Do they use different number of bits? How many bits? Maybe some are redundant? 'C' doesn't use the term Single, but VB does and FORTRAN did (maybe still does). It looks to me like maybe I should be learning a bit about VB. Many of the terms are used in VB. But, if they are indeed VB terms, do they have identical meanings? If so, that seems a bit odd to me since AB is/was coded in C++. Maybe someone can suggest one or more sources which might act as an introduction to, or present a 'freshman' level description of OLE? Thanks, -- Keith
