How to convert a array

I have an array defined as varient, I need to convert it into single, but I do not know the dimension of the array, ie. how big it is.

Any suggestion?

Dim BLOBdata() As Single

How to define the dimension?

can you explain more in detail what exactly you are trying to achieve, it is not clear for me.

if you don't know the dimensions, use UBOUND(variable) and LBOUND(variable) to know the upper and lower bound.
if you assume that it has more than 1 dimension:
UBOUND(variable, 0) get's the first dimension's upper bound, UBOUND(variable, 1) the one of the second etc. until ubound returns -1

I get a array back from a function return,
a(..., x,.... )

x is an array of varient,
Now I need to convert x to a Single type array, how to do it?

I tried Dim BLOBdata(UBound(Waveform)) As Single

but it said constant data required.

you have to make that in 2 lines:
'first declare the array variable without size
Dim BLOBdata() As Single
'now redimension the array
REDim BLOBdata(UBound(Waveform)) As Single
