Marshals an array objects into an unmanaged array of VARIANTs.

public static GetVARIANTs ( object values, bool preprocess ) : IntPtr
values	object	An array of the objects to be marshalled
preprocess	bool	Whether the objects should have troublesome types removed before marhalling.
return	System.IntPtr

		public static IntPtr GetVARIANTs(object[] values, bool preprocess)
		{
			int count = (values != null)?values.Length:0;

			if (count <= 0)

			IntPtr pValues = Marshal.AllocCoTaskMem(count*VARIANT_SIZE);

			IntPtr pos = pValues;

				else
