Handling Data
Data can be processed in a number of ways on forms, depending upon the application’s purpose. Older (legacy) software may process data in much the same way as before but your application might be to give it a visual ‘front end’, i.e. your form acts as an event trigger to an existing process with perhaps the parameter validation being tied to the form and processing ‘shelled out’ to the existing process.  File Handling is possible (and is easy) directly from VB3, however, most applications that manipulate data do so from managed databases. There are a number of ways of connecting to data with later versions of VB, (which we will look at later) but VB3 is more limited. VB3 however, does have a Database Manager tool  and this will be explored later.
