when i use the function:
HRESULT CVIFUNC ExcelRpt_GetRangeDataType(CAObjHandle worksheetHandle, const char *cellRange,enum ExREnum_ExDataType *dataType)
when cellRange is D2:F510000 ，i found it spend too much time ,about 110 seconds。
when i use timer() to find the time executed inside of ExcelRpt_GetRangeDataType,
i found the code below spend about 90 seconds.
if (Varray)
{
for (i=0; i < dim1; i++)
for (j=0; j < dim2; j++)
CA_VariantClear (&Varray[i*dim2+j]);
CA_FreeMemory (Varray);
}
can anyone have some advice about read large range of cells .
