I am working in Visual Studio 2005.
Is it possible to use mutliple types with the same array

eg Dimm arr(10) as Object

arr(0) = "Hello"
arr(1) = False
arr(2) = 23

yes.   you want to use just one "m" in a dim.

Not the solution you were looking for? Getting a personalized solution is easy.

Thanks for that!
The dimm was a typo.
Appreciate the quick answer!
Jens FiedererTest Developer/Validator

Note, though, that this is really a case of using subclasses, and everything being a subclass of Object.

If you declared

dim arr(10) as Shape

And Circle, Square, and Triangle all interited from Shape, you could put
Circles Squares and Triangles in arr ... but not, for example, an arraylist.

I think I understand your last comment.
I just want to be able to eg do the following
Dim A(2) As Object
A(0) = "Tree"
A(1) = xlYesNoGuess.xlYes
A(2) = 3456376

I am assuming that this is okay.

Jens FiedererTest Developer/Validator

That will WORK, but it is dangerous.

Later, when you reference A(2)...and maybe expect to find a string rather than a number...you might blow up.

It is generally good programming practice to make the type of the Array as specific as possible, to minimize the chance of a type mismatch in the future.
