FFT2D not happening

I am using National Instruments Measurement Studio for .Net.
I am using Visual Studio 2008 as the .Net compiler.

=============================================


Dim InpDataCom(1, 1) As NationalInstruments.ComplexDouble

InpDataCom(0, 0).Real = 1
InpDataCom(0, 0).Imaginary = 0
InpDataCom(0, 1).Real = 0
InpDataCom(0, 1).Imaginary = 0
InpDataCom(1, 0).Real = 3
InpDataCom(1, 0).Imaginary = 1
InpDataCom(1, 1).Real = 5
InpDataCom(1, 1).Imaginary = 0

NationalInstruments.Analysis.Dsp.Transforms.Fft2D(InpDataCom,True, 2, 2)

Dim InpDataCom(1, 1) As NationalInstruments.ComplexDouble

For Each w In InpDataCom

            MessageBox.Show(w.ToString())
Next

===========================

The above code is giving the following output :

1 + 0i
0 + 0i
3 +1i
1 + 1i
5 + 0i

Hence  it seems the input and the output are the same.

So no 2d transform took place.

Whats wrong with the above code ?
