The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

VB6 and earlier needed Set and Let because of non-indexed default properties, which thankfully went away when .NET was first released.

For example:
Dim rst As ADODB.Recordset
Set rst = ...

Dim foo As Variant 
foo = rst["Bar"]

  • The Recordset class doesn't have an indexer, but it has a default property called Fields which does.
  • The indexer returns an ADODB.Field object, with a non-indexed default property called Value.
  • At this point, the compiler wouldn't know whether you want the variable to contain the field object or the field's value.
  • Therefore you have to use Set if you want the field object, and Let (or nothing) if you want the value.

Fun times! Dead | X|
