performing calculations on time data
I have googled and searched this group and have not found exactly what i
am looking for. everything i have seen is for performing functions in the worksheet and not in vba code. i'll set up the prolbem, explain what i need, and give you what i have come up with so far. i have two columns with time data. i want the third column to show the difference between the time. so if one 13:30 and the other is 14:00 i want the 3rd column to show :30. or if one is 14:00 and the other is 13:30 i want the 3rd column to show :30 A B C 13:30 14:00 :30 14:00 13:30 :30 the all cells are formatted as general. the code snippets below are for excel2000. If .Cells(row, colSchedule).Value .Cells(row, colActual).Value Then .Cells(row, colVariance).Value = .Cells(row, colSchedule).Value - _ .Cells(row, colActual).Value Range(.Cells(row, colVariance)).NumberFormat = "hh:mm" Else .Cells(row, colVariance).Value = .Cells(row, colActual).Value - _ .Cells(row, colSchedule).Value Range(.Cells(row, colVariance)).NumberFormat = "hh:mm" End if i have also attempted using Range(.cells(row,colSchedule).value etc.... in both attempts the comparison works fine (which boggles my mind), however the cell assignment/mathematic operation fails with a mismatch object error. all cells formatted as general. i don't know if that is the problem, but i doubt it since if i do this in the sheet, eg =B1-A1, i get no problem. The code does not make it to the Range......NumberFormat so i have no idea if that will work or not. I do not think the builtin Time function(time(h,m,s) will work since i cant seperate the information by hour.minutes. i have read how excel stores time data, but i do not (hope not) think that applies. what this is not is a payroll sheet or some sort of userform. based on the if statements above some other things get processed and sorted out, i have not included them for brevity. there will also be a future comparison based on the result of the calculation to the effect of if it is 30 then something happens, if it < 30 something else happens. i hope this is clear.
