Problem in calling Excel Run fucntion from VC++
Hi,
i have a problem in calling excel Fourier analysis functions from vc++.
the below line gives a error while running.
the error rises in excel sheet.
Code:
mp_application>Run("ATPVBAEN.XLA!Fourier",
(const variant_t)p_work_sheet>GetRange(p_range_pointer>Item[dw_dest_row1][dw_dest_col1],p_range_pointer>Item[dw_dest_row1][dw_dest_col1]),
(const variant_t)p_work_sheet>GetRange(p_range_pointer>Item[dw_dest_row1][dw_dest_col1],p_range_pointer>Item[dw_dest_row1][dw_dest_col1]),
false,false);
ERROR is : fourier analysis  input range must be contagious reference.
mp_application is a Excel::_ApplicationPtr
p_work_sheet is a Excel::_WorksheetPtr
please help me in finding out, what mistake i am doing while sending the parameters.
help is highly applicable.
thanks in advance.
 satya.

"contagious" or "contigious"?
If the latter  then http://www.google.com/search?hl=en&r...&aq=f&oq=&aqi=

The first link ( http://www.mrexcel.com/forum/showthread.php?t=35738 ) from the Google Search I referred to in my previous post explains you very clear the most possible reason of this message:
This means that the selection must be a single cell or the selection must be a rectangular area, not multiple unconnected areas

Perhaps, it is NOT contiguous enough?
The code snippet you have posted doesn't show how "contiguous" this area is!

Code:
(const variant_t)p_work_sheet>GetRange(p_range_pointer>Item[dw_dest_row1][dw_dest_col1],p_range_pointer>Item[dw_dest_row1][dw_dest_col1]),
(const variant_t)p_work_sheet>GetRange(p_range_pointer>Item[dw_dest_row1][dw_dest_col1],p_range_pointer>Item[dw_dest_row1][dw_dest_col1]),
This doesn't look like a range to me, more like a single cell.
fourier analysis doesn't work well with only one value.

getrange function converts the given col and row number to range pointers. so i think i am passing range pointer only.
