All,
Please can anyone let me know why this is not working? I have the following code as a module in my access database:

Public Function NetWorkhours(dteStart As Date, dteEnd As Date) As Single

Dim intGrossDays As Integer
Dim intGrossHours As Single
Dim dteCurrDate As Date
Dim i As Integer
Dim WorkDayStart As Date
Dim WorkDayend As Date
Dim nonWorkDays As Integer
Dim StartDayhours As Single
Dim EndDayhours As Single
NetWorkhours = 0
nonWorkDays = 0
'Calculate work day hours on 1st and last day
WorkDayStart = DateValue(dteEnd) + TimeValue("08:00am")
WorkDayend = DateValue(dteStart) + TimeValue("05:00pm")
StartDayhours = DateDiff("n", dteStart, WorkDayend)
EndDayhours = DateDiff("n", WorkDayStart, dteEnd)
'adjust for time entries outside of business hours
If StartDayhours < 0 Then
StartDayhours = 0
End If
If EndDayhours > 9 Then
EndDayhours = 9
End If
'Calculate total hours and days between start and end times
intGrossDays = DateDiff("d", (dteStart), (dteEnd))
intGrossHours = DateDiff("n", (dteStart), (dteEnd))
'count number of weekend days and holidays (from a table called "Holidays" that lists them)
For i = 0 To intGrossDays
dteCurrDate = dteStart + i
If Weekday(dteCurrDate, vbSaturday) < 3 Then nonWorkDays = nonWorkDays + 1
If Not IsNull(DLookup("[HolDate]", "tblHolidays", "[HolDate] = #" & Int(dteCurrDate) & "#")) Then nonWorkDays = nonWorkDays + 1
Next i

'Calculate number of work hours
Select Case intGrossDays
Case 0
'start and end time on same day
NetWorkhours = intGrossHours
Case 1
'start and end time on consecutive days
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
Case Is > 1
'start and end time on non consecutive days
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
End Select
End Function

The actual function works fine, ALTHOUGH I have set-up an "Outage Calculator" for the line manager to use. It is really simple. Contains three text boxes that are not bound to a table.
Box 1 --- Date\Time_From
Box 2 --- Date\Time_To
Box 3 --- Networkhours([Date\Time_From],[Date\Time_To])

Default value for box 1 and box 2 is Now() so the Line manager just adjusts the time and dates to suit his needs eg.
Date From Date To Network Minutes
20/11/2009 08:50:22 20/11/2009 10:50:22 120

The problem that I have is it seems to be ignoring weekends for some reason. If I put in:

Date From Date To Network Minutes
14/11/2009 08:50:22 15/11/2009 08:50:22 499

The 14th and 15th are Saturday and Sunday. It should only raise minutes for weekdays.

Any Help would be much appreciated.

noone is going to respond to this because it is unreadable and because of that, incomprehensible. fix it and people will give you some help
 
Weekday(dteCurrDate, vbSaturday) < 3

Will make saturday 1 and sunday 2, which will make it ignore the saturday and sunday....

There is also a check for holidays with will make it skip holidays...

Apologies for the poor formatting, I didn't realise it had pasted in like that. The datasheet should look more like this

Thank You for your quick reply, The code already has the lines:

If Weekday(dteCurrDate, vbSaturday) < 3 Then nonWorkDays = nonWorkDays + 1
If Not IsNull(DLookup("[HolDate]", "tblHolidays", "[HolDate] = #" & Int(dteCurrDate) & "#")) Then nonWorkDays = nonWorkDays + 1
Next i

Is this not the same as what you are saying?
 
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9

Is only beeing done in the more than 1 day option, if there is one day difference you do not account for "weekend" days...

Thank You sooo much. I never spotted that. Sometimes the blindingly obvious escapes the untrained eye ha ha. Would I be right in saying that the code should look like this at the end?

'Calculate number of work hours
Select Case intGrossDays
Case 0
'start and end time on same day
NetWorkhours = intGrossHours
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
Case 1
'start and end time on consecutive days
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
Case Is > 1
'start and end time on non consecutive days
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
End Select
End Function
 
I havent made a study of the code, but try it...

And at the very least it should look like:
Code: 
'Calculate number of work hours
Select Case intGrossDays
    Case 0
        'start and end time on same day
        NetWorkhours = intGrossHours
        NetWorkhours = NetWorkhours - (nonWorkDays * 1)
        NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
    Case 1
        'start and end time on consecutive days
        NetWorkhours = NetWorkhours - (nonWorkDays * 1)
        NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
        NetWorkhours = NetWorkhours + StartDayhours
        NetWorkhours = NetWorkhours + EndDayhours
    Case Is > 1
        'start and end time on non consecutive days
        NetWorkhours = NetWorkhours - (nonWorkDays * 1)
        NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
        NetWorkhours = NetWorkhours + StartDayhours
        NetWorkhours = NetWorkhours + EndDayhours
End Select

It could work, then again maybe not.... test it.
 
namliam,
Thank You for your help so far, but it is just coming out really confused now. I have inputted the code to see if it would work and it puts in -9 now so I looked at the code but I just can't get my head around it at the end. I know what you are saying with

NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9

Is only beeing done in the more than 1 day option, if there is one day difference you do not account for "weekend" days...

But I can't see how to implement this. I am not up to the standard in VBA that I should probably be at, but there is only one way to learn. Do you have any idea's?

Keith
 
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9

Well.... intGrossDays is 1 (intGrossDays = DateDiff("d", (dteStart), (dteEnd)))
nonWorkdays is 1 (as per it is saturday)

1 - 1 - 1 = -1 * 9 = -9, makes perfect sence to me :)

The problem is in your logic, not the code itself... It basicaly assumes that the start day is a weekday.... not a weekend... or even holiday.
 
Thank you for your help so far. I have adjusted the code to the following:

Option Compare Database
Public Function NetWorkhours(dteStart As Date, dteEnd As Date) As Single

Dim intGrossDays As Integer
Dim intGrossHours As Single
Dim dteCurrDate As Date
Dim i As Integer
Dim WorkDayStart As Date
Dim WorkDayend As Date
Dim nonWorkDays As Integer
Dim StartDayhours As Single
Dim EndDayhours As Single
NetWorkhours = 0
nonWorkDays = 0
'Calculate work day hours on 1st and last day
WorkDayStart = DateValue(dteEnd) + TimeValue("08:00am")
WorkDayend = DateValue(dteStart) + TimeValue("05:00pm")
StartDayhours = DateDiff("n", dteStart, WorkDayend)
EndDayhours = DateDiff("n", WorkDayStart, dteEnd)
'adjust for time entries outside of business hours
If StartDayhours < 0 Then
StartDayhours = 0
End If
If EndDayhours > 9 Then
EndDayhours = 9
End If
'Calculate total hours and days between start and end times
intGrossDays = DateDiff("d", (dteStart), (dteEnd))
intGrossHours = DateDiff("n", (dteStart), (dteEnd))
'count number of weekend days and holidays (from a table called "Holidays" that lists them)
For i = 0 To intGrossDays
dteCurrDate = dteStart + i
If Weekday(dteCurrDate, vbSaturday) < 3 Then nonWorkDays = nonWorkDays + 1
If Not IsNull(DLookup("[HolDate]", "tblHolidays", "[HolDate] = #" & Int(dteCurrDate) & "#")) Then nonWorkDays = nonWorkDays + 1
Next i

'Calculate number of work hours
Select Case intGrossDays

Case 0
'start and end time on same day
If Weekday(dteStart) = 7 Then
NetWorkhours = 0
if Weekday(dteEnd) = 1 Then
Networkhours = 0
Else
NetWorkhours = intGrossHours

End If

End If

Case 1
'start and end time on consecutive days
If Weekday(dteStart) = 7 Then 'start date = saturday so end date would equal sunday
NetWorkhours = 0

If Weekday(dteStart) = 1 Then 'start date = sunday so ignore first day
NetWorkhours = NetWorkhours + EndDayhours

If Weekday(dteEnd) = 7 Then 'end date = Saturday so ignore last day
NetWorkhours = NetWorkhours + EndDayhours
Else
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
End If

End If

End If

Case Is > 1
If Weekday(dteStart) = 7 Then 'start date = saturday
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + EndDayhours

If Weekday(dteStart) = 1 Then 'start date = sunday
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + EndDayhours

If Weekday(dteEnd) = 7 Then 'end date = Saturday
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours

If Weekday(dteEnd) = 1 Then 'end date = Sunday
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours

Else
NetWorkhours = NetWorkhours - (nonWorkDays * 1)
NetWorkhours = (intGrossDays - 1 - nonWorkDays) * 9
NetWorkhours = NetWorkhours + StartDayhours
NetWorkhours = NetWorkhours + EndDayhours
End If

End If

End If

End If

End Select
End Function

Obviously it still isn't working and I have actually ripped all of my hair out now. Sorry to sound lame but I have made up all of the script for the Case statements at the end and it does not come up with any errors, but seems to be coming up with Networkhours = 0 for nearly all date combinations now. Is there an easier or better, more correct way to write what I have written in the case statements?

Thank You

:eek: OK, I have gone and done some indenting for you....

:eek: You really really should make this a habbit ! As (to me) this makes it terribly obvious what/where the problem is.

Also please
1) use the code wraps not the quote wraps
2) use option explicit, this can be turned on by default Tools > Options > Editor Tab > Tick the "Require Variable Declaration"

I hope your mistake is more or less clear to you?

Tip: It has to do with the IF nesting.
 
Namliam,
I do use indents but when I pasted the code form Access module it does not include the indents. I have printed your code and compared it to the module on the database. There are no differences between the two. IT STILL DOES NOT WORK!! I have added the Option Explicit.

If you know why it does not work please tell me

If you know why it does not work please tell me

Yes if you use Code tags its shows so, if you use Quote it doesnt... basicaly making your posted code quite unreadable.

And yes, all I did was indent it... changed nothing.

Your problem is in the nested if's like I hinted you earlier...
Code: 
If x = 1 Then 
    do something 
    ' only get here if x = 1
    if x = 2 then
        do something 
        ' only get here if x = 2
        if x = 3 then
etc...
        else
            Do Something
            ' Only get here if x not equal to 1 and 2 and 3....
etc...
That is what you have... you never get to the check where x=2 for anything that makes sense because x will only be 1 at that point.

Any other day will never end up in your "else" becuase of this same nesting problem... Instead (without detailed research though) it should look something like so:
Code: 
If x = 1 Then 
    do something 
    ' only get here if x = 1
[B]Else[/B] ' Not equal to 1 thus could be 2 or 3
        if x = 2 then
            do something 
            ' only get here if x = 2
    [B]Else[/B] 
            if x = 3 then
etc...
            else
                Do Something
etc...
Or use an elseif, something like so:
Code: 
If x = 1 Then 
    do something 
    ' only get here if x = 1
elseif x = 2 then
    do something 
    ' only get here if x = 2
elseif x = 3 then
etc...
else
    Do Something
    ' Only get here if x not equal to 1 and 2 and 3....
etc...

I hope that gives you the general idea :D
 
Namliam, or anybody,

Been working really hard on this with my limited knowledge. Still encountering a few problems.

Case1 and case>1 are still not working properly and I think although I am heading down the right road the code is still not entirely correct.

Please Note: Although the code title is NetworkHours I have * 540 to make it minutes in a 9 hour day so please ignore that.

Here is the final code that I have come to:

Some things that jump to sight:
- You are not indenting properly (yes I nitpick, but it IS important to always do this)
- You changed to minutes over hours, then rename your function?
- You changed to minutes over hours, yet the initial settings are still hours: "EndDayhours = 9", doesnt make sence. You are beeing totaly inconsequent with this hours vs minutes thing.

I have an overall feeling like this is somewhat overly complex, but I would have to spend some time thinking about this to be able to rewrite this.
 
Namliam, Everyone

Although very crude I have finally cracked this bit of code with the help of another from my office.

If you wish to use this piece of code then please publish although I know that it could probably be re-written differently to suit different needs.

Glad you have it working :) like you said there is probably easier way to do this... but its working :D

Good job !
