I think this workaround is better than a global function:

1) Dim a local variant.
2) Assign the object you want to type cast to the variant
3) Assign the variant to the specific object type you want -- variants will
do the appropriate type casting internally if your doing a valid type cast
(but will throw an unhandled illegal cast exception if you provide the wrong
data types, just as if you did the type cast the traditional way).

So instead of doing this:


  dim x as Object
  dim c1 as Class1
  
  x = new Class1

  c1 = Class1(x) //"To many parameters" or some such error
  

Do this instead:

  dim x as Object
  dim v as variant
  dim c1 as Class1
  
  x = new Class1
  v = x
  
  c1 = v
  

HTH,
