I have designed an access application that logs emails that come into a department. However, the team leader has asked me to create a report to work out if emails were answered within a 24 hour period.
Is there a method to do this. It is not something I have attempted to do within access before.

I'm currently stuck on trying to create a worksheet which calculate the balance remaining at the end of each Monthly Payment Period.
Monthly Payment Period: 1 to 300
Initial Balance: balance outstanding at the beginning of the Monthly Payment Period.
Interest: calculated by multiplying the Initial Balance by the APR (5%) divided by 12
Balance Remaining: calculated by adding the Interest and subtracting Total Monthly Payment.
The final Balance Remaining should be exactly £0.00.

Calculate time across midnight in ms access
--------------------------------------------------------------------------
Hi,
I have created a database to store patient arrival date, arrival time and departure time.
I am trying to set up a query to calculate the total waiting time for each patient from arrival time to departure time.
At the minute I can calculate the total waiting time in minutes by:
Minutes: DateDiff("n",[Time Arrived],[Time Left Department])
and the total waiting time in hours and minutes by the following:
Waiting Time: [Minutes]60 & Format([Minutes] Mod 60,":00")
But this does not work accross midnight, as it gives a negative time for anyone seen before midnight and discharged after midnight.
Any help much appreciated.

I have a table that contains a person ID, a start date for that person, and a GroupType. I want a way to count the number of people who started within ANY 40 day period. Then depending on that number , assign a value to the GroupType field (ie. if the no. of people is 1-15 then groupType = groupA, if its 16-30 then groupType = groupB, if its over 31+ then grouptype = GroupC. This needs to be re-counted every time a new record is added.
As well as having the groupType visible on the form for that person, I also want to be able to run a report showing all people, their start date and group type. Note that when start dates are entered these may be either future dates as well as dates in the past.
If possible, I would also like to track /store when a person's group type changed in another or the same table perhaps.

I have a situation where I am using a maketable query to create a table and then I need to use append queries to then add additional records to the created table - some of these are just run once and some multiple times.
if possible, I do not want to hard code the query multiple times i.e.
Code:
DoCmd.OpenQuery "qryCreate_1"
DoCmd.OpenQuery "qryAppend_1"
DoCmd.OpenQuery "qryAppend_1"
DoCmd.OpenQuery "qryAppend_1"
etc
So is there a way I can run the make table query and then get some sort of loop to run the append query a number of times ?

Is it possible to copy a record 'n' number of times, incrementing the date by either days, months, weeks etc?
I have a regular payments table that will need to be edited at some point should either dates, or amounts change, but... regardless of the size of the table, it's not a problem, as these will be moved to a different table and deleted once paid.
Given the example, would it be possible to copy this record and additional 5 times, incrementing the date by one week.

I have a working dB which can calculate a shift duration and sum total all shifts worked within a period for the purpose of producing a labor report for payroll. I have successfully used the DateDiff function and converted the minutes to HH:MM on my form and reports. Now I want to calculate elapsed time for a specific period within a shift, I'll call it OtherHours and I am aiming to calculate a portion of time that meet the following conditions below. I am using field names of [PunchIn] and [PunchOut] and both are of type General Date.
IF [PunchOut] ISNOT Saturday,Sunday
EXIT FUNCTION
ELSE
IF [PunchOut] ISNOT Between Midnight and 0559 hours
EXIT FUNCTION
ELSE
DATEDIFF ("n", <MIDNIGHT>, [PunchOut])
My thoughts are to solve the DateDiff portion and then figure out how to apply the conditions within the IF statements.

In my Access 2010 database there is a form with a large number of checkboxes enabling me to select/deselect certain record details.
Each click on one of the checkboxes triggers a VBA routine setting true/false values in one of several tables linked to the main table.
A query over all records is filtered by the true/false values of the linked tables and the resulting set of records is displayed in the (continuous) form.
The header of the form contains a text field with the value "=GetRecCount()" displaying (correctly, but randomly fast) the number of records selected:
Code:
Function GetRecCount() As String
Dim NumRecs As Long
Dim rs As Object
On Error Resume Next
Set rs = Forms![Super Search].RecordsetClone
rs.MoveLast
NumRecs = rs.RecordCount
Set rs = Nothing
GetRecCount = Format(NumRecs, "##,###")
End Function
Now, the funny thing is that each click on one of the boxes results in 1 call of the VBA routine setting table values, but 21 calls (!) of the text field "=GetRecCount()" in the form. I have established this by incrementing a public variable at each pass.
Why a field in a form is updated 21 times when a filter is applied?

I have to make a form with multiple sections. Each section has n questions to which corresponds a numerical value from 1 to 4.
Example:
Question 1 value 2
Question 2 value 1
Question 3 value 3
Question 4 value 2
Question 5 value 4
Question 6 value 2
I have to choose the most recourrent number like the Excel MODA function then in this example is 2.But if there are more then one recurrence with the same times i must choose the highest one.
Question 1 value 2
Question 2 value 1
Question 3 value 3
Question 4 value 2
Question 5 value 4
Question 6 value 4
In the example above number 2 and 4 recur the same number of times and i must choose the number 4 because is the higher.
There is not a MODA function in Access, even if Excel, with the second example returns the most recurrent but the lower value 2.

I am trying to get a module set-up that will add a number of workdays (no weekends, no holidays) to a date that is mentioned in a form and put the resulting deadline date in another field on the same form (date or remaining days to deadline would be even better).
Now it gets a little tricky, the module will need to select different amounts of workdays to be added to the date in the form depending on what status is selected (different statusses have different amounts of days).
I'll probably need:
List of holidays
List of days required per status
Start date (to which the days can be added).
Example:
Status = "DQ" which has 2 days to work with.
Start date in form = "21/03/2014".
Result = 25/03/2014 or preferably "2 days remaining".

I want to select a date range from "Production" table where it agrees to the Dept_ID too. And then calculate the summation of the columns "hours", "produced" & "waste" of that particular range selection.
This is my code:
Code:

Private Sub cmdCal_Click()
Dim sql As String
Dim rs As Recordset
Dim qdef As DAO.QueryDef
Dim hours, waste, produced As Integer

But it returns nothing, When i remove the errorHandler, it says that no records were found.

What I have is two fields, one is a simple date and the other is slightly more complex as it holds a date but in a different structure (a dated case number).
The case numbers are for example, 150211551223 the date being the first 6 numbers and equaling to 11/02/2015. so the code will need to grab this data, spin it around and convert it.
The formula will then be:
simpledate - convertedcasenumberdate = days between.
(simpledate will always be the latest date of the two).

How to implement a functionality into my access database. The related tables required for this functionality can be found as an attachment.
When the information has been entered into the tables by the user, I would like to calculate the difference between the information for each part within the same table. The main columns for which the difference have to be calculated are: [RefObsInfo->RefSources] and [AltObsInfo->StatusAltSource] and [GenObsInfo->GenSources]. The values for these fields are restricted to 3 or 4 different ones. I also would like to show if the GenEstAvailable columns are changed, but that's for later.
In order to calculate this difference a query has to select for each Part the information related to the last date AND a date which has been specified by the user (with the previous date as max). For this the user is asked to give a from date, which she/he can select from a combobox. This combobox has a standard selected value which is the MaxDate-1, i.e. the previous date. The difference should be calculated from the previous date to the last date. I would prefer to give each (predefined) difference a specific action to show the user the difference in a matter of seconds.
