It is a method of accessing data in different ways e.g getting a record from a database by specifying any of x field values. There will be x subroutines all with the same name and which one the VB system uses depends on what you entered. Biggest advantage is that you simply enter a field value and never specify what field it actually is. Another record can be obtained using the same input box but now you specify a different field value to find.
You could get exactly the same result by having x possible inputs with a check box against each. You would then have to code to determine which check box was ticked, the data supplied and then either call one of x subs all with a different name or use x IF or CASE statements to get the record with the field value specified.
Overloading is giving multiple procedures/functions (methods) the ability to share the same name. The key difference between them, which allows them to co-exist, is that they have different parameters.
I don't believe VB6 has this which makes it short of being a complete OOP language. VB.NET however, does support overloading.
Some keywords to look for; "polymorph(ism)", "overrides"
Could somebody please explain to me what "Procedure overloading" is in Visual Basic?
