Any idea on how I can check if the variant contains an array,
considered IsArray returns true for ranges?

thanks

If the variable is truly a Variant, then it cannot contain a reference to a
Range object. When you do this:

Dim v As Variant

v = Range("A1:A10")

The variable v is being filled with the *values* from the range A1:A10. So
the IsArray function is correct - the Variant v really does contain an array
at that point.

Maybe I'm not understanding your issue - what is it you are trying to
accomplish?

Dim v as Variant
set v = Range("A1:A10")

v will hold a range reference.

I assume he has a generalized function that is passed in a variant which may
contain a range. This would be a common need in handling a parmarray

Thanks for the correction, Tom. I guess I typically use variables of type
Object to do that, so I wasn't even aware (or forgot) you could do the same
thing with a Variant.

Even if you declare it as an object, IsArray will still return true.

The problem here is that it looks like a range is automatically
converted to a variant array whenever a variant is expected.

Function TestArray(a)
TestArray = True
On Error Resume Next
If IsError(UBound(a)) Then
TestArray = False
End If
End Function

I suppose it would return false for 0 dimensioned arrays.

Check for a range first

if typename(varr) is "Range" then
' it's a range
elseif isarray(varr) then
' it's an array

Thanks Tom.

As far as you know, am I going to get "true" for isarray for others
variant/object/* combinations?
thx

I wouldn't think so.

for example:

? isarray(thisworkbook.Sheets)
False
? isarray(Activesheet.Shapes)
False
? isarray(Range("A1"))
False
? isarray(Range("A1:A10"))
True

I can't think of another object that returns an array for the value (or
default) attribute. That doesn't mean there are not any, but I can't think
of one.
