Time calculation..??

I want to be able to subtract(endtime-starttime) and have (repairtime+setuptime+pmtime) equal the value from endtime-starttime. EndTime and Starttime are 8:00(military time) and repairtime, setuptime, pmtime are 60(integers).

This is the code I have come up with so far:
MyTime = (Val(txtEndTime) - Val(txtStartTime))
MyWorkTime = (Val(txtRepairTime) + Val(txtSetupTime) + Val(txtPMTime))

If Not MyTime = MyWorkTime Then
MsgBox "The hours or minutes do not equal the total hour and minutes from Start Time and End Time."
txtRepairTime.SetFocus
Exit Sub
End If

The problem is when the correct time is put in the msgbox still comes up, but if the time is correct then I want the record to be added. And when the time is incorrect I don't want the record to be added. See the only way to find out if the time is correct the user will press on the add button and then the msgbox comes up only when the time is incorrect. But I don't think the times are even being compared. Can anyone help me with this problem?

Thanks jeffro

could u give the data of the textfields

StartTime = 8:00
EndTime = 9:00

RepairTime = 40
SetupTime = 20
PMTime = 0

Those are some examples.

jeffro

instead of val convert it time an try Cdate(txtEndTime,hh:mm) etc.. may u will get the solution

I tried the example you gave me but I get an error and it highlights the ,.

Then I tried just cdate(txtendtime)- cdate(txtstarttime), but that didn't work either.

any other suggestions?

thanks jeffro

Jeffro,

You might try the DateDiff function, similar to the following.

Code:

---

Private Sub Command1_Click()
    Dim starttime As String
    Dim endtime As String
    Dim repairtime As Integer
    Dim setuptime As Integer
    Dim pmtime As Integer
   
    Dim interval As Integer
    Dim totaltime As Integer
   
    starttime = "08:00"
    endtime = "09:00"
    interval = DateDiff("n", starttime, endtime)
   
    repairtime = 40
    setuptime = 20
    pmtime = 0
    totaltime = repairtime + setuptime + pmtime
   
    If interval = totaltime Then
        MsgBox "Times match"
    Else
        MsgBox "Times do not match"
    End If

End Sub

Hey thanks jbart, that worked great! Is there a way I can stop the adding of the new record if the time does not match?

Thanks jeffro

Never mind I just made a call and used it in the if end if statement for the time calculation.
