VB.net/VB 2005 Using multiple types in an array
Hi
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
etc

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.
Thanks

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.

The dimm was a typo.
Appreciate the quick answer!
