trying to write =sum function from vb to sum some of the cells in excel
when i write


  .Cells(10,13).Formula = "=SUM(C13,E13,G13,I13,K13,M13,O13,Q13)"

the above statement writes the string as it is it writes =SUM(C13,E13,G13,I13,K13,M13,O13,Q13 in the specified cell (10,13)instead of calculating the value from the given cells. Can some one tell me how to do this please see that the cells are from alternate columns but in the same row.

thanks in advance. Its kind of urgent
Thanks agian

xlsheet.Application.cells(5, 1).Formula = "=sum(e1,e2,e3)"

Use Value ie

.Cells(10, 13).Value = "=SUM(C13,E13,G13,I13,K13,M13,O13,Q13)"

For i = 0 To cnt - 1
        r = m_iCancelled + 2 + i  '//////// this would be the starting row

With m_oXLSheet
               .Cells.Range(str).Insert  ''''''''''''insert one row
               .Cells(r, 1) = strAry(i)   ''''''''''''insert value in col 1 stored in array

Hi JuniorDeveloper2000 ,

Your code is doing what you are telling it to - putting the formula in the cell.

Now you need to cause a calculation of that formula, like you would use F9 in Excel.

Try using the Calculate method on your worksheet object
        m_oXLSheet.UsedRange.Columns("A:C").Calculate
    change the columns to what ever columns you want.


Here is a copy of MS help on the subject;

  Calculate Method
       
  Calculates all open workbooks, a specific worksheet in a workbook, or a specified range of cells on a worksheet, as shown in the following table.

  To calculate Follow this example
  All open workbooks Application.Calculate (or just Calculate)
  A specific worksheet Worksheets(1).Calculate
  A specified range Worksheets(1).Rows(2).Calculate

  expression.Calculate

  expression   Optional for Application, required for Worksheet and Range. An expression that returns an object in the Applies To list.

  Example
  This example calculates the formulas in columns A, B, and C in the used range on Sheet1.

  Worksheets("Sheet1").UsedRange.Columns("A:C").Calculate

Hi JD2000,

If you want the sum placed in the cell instead of the formula, you could try

.Cells(10, 13) = Excel.Application.WorksheetFunction.Sum([C13], [E13], [G13], [I13], [K13], [M13], [O13], [Q13])

 or if its not recognizing the [ ] shorthand, use:

.Cells(10, 13) = Excel.Application.WorksheetFunction.Sum(Range("C13"), Range("E13"), _
 Range("G13"), Range("I13"), Range("K13"), Range("M13"), Range("O13"), Range("Q13"))

it started working when i change the column format from text to numeric.. i know it is kind of silly.
.cells(row,col).values = "sum(a1,b1,c1)" worked when i change the column format to numeric.
Thanks all for your effort
