Invalid use of Object :/

Hello ppls,

well.. it looks like ive some difficulties with private class module handling, im want to verify if a class not defined in my array (fletters) but when im try to check with "If Not FLetters(Z1) = Nothing Then" ive got the 'Invalid use of Object' error, and i cant figure out how can i verify this... :(

so, heres the declaration
Private FLetters() As LetterHandle

in the form_load event:
ReDim FLetters(0)

and somewhere in the code ive increased the arrays index, and 'bind' the new class:

ReDim Preserve FLetters(C)
Set FLetters(C) = New LetterHandle

... some index of this array is stay 'Nothing'...

i know my problem looks a little bit lame, but ive never tried to use this before..

pls help
jim.

Use the function IsNull() to check, instead of if object = null/nothing

not works :(

any other idea?

jim.

ive tried IsEmpty().. but ive got the sames like with IsNull()...

the arrays index not empty, and not null, but its Nothing.. so how can i verify? :( *sniff*
