Custom autonumber format in access

I am trying to have custom autonumber and found the below url helpful.

https://www.experts-exchange.com/questions/23238522/Looking-for-custom-autonumber.html

Is there anyone who can help to make it in this format JBddmmyy-1 or JBddmmyyxx
eg. JB021213-01, JB021213-02, JB021213-03
or
eg. JB02121301, JB02121302, JB02121303
i.e each day it will start from 01 with that date format
eg. JB031213-01, JB031213-02, JB031213-03 for tomorrow

Is there anyone who can make the changes and upload it here or post the code here

Hi,

pls try

Function getNextNo() As String
Dim intMax As Integer, curVal, newVal, yr As String
theDate = Format(Date, "ddmmyy")
curVal = Nz(DMax("RandomNum", "Table1")) 'Change to your table
If Mid(curVal, 3, 6) = theDate Then
    If Len(curVal & "") > 0 Then
        intMax = Left(curVal, 2)
        newVal = theDate & "-" & Format(intMax + 1, "00")
        Else
        newVal = theDate & "- 01"
    End If
    Else
    newVal = theDate & " - 01"
End If
getNextNo = "JB" & newVal
End Function

Many thanks to both
I appreciate if you can explain what your code does.
Just want to know. Please explain when you are free.

The following line formats the date as ddmmyy with JB at the beginning. For instance, todays' date is stored in the variable sPrefix as JB021213:

sPrefix = Format(Date, "JBddmmyy")

This next line looks only at the records in your table where your ID field begins with the same prefix as what is stored in the variable (using the LIKE keyword and a wildcard '*'). It gets the maximum value of the last 2 characters and adds 1 to that value. If there is no record yet for the day, the NZ function tells it to return a 0 (which ends up having a 1 added to it).

bSeq = Nz(DMax("Right([ID],2)", "TableName", "[ID] LIKE '" & sPrefix & "*'"), 0) + 1

Finally, this line returns the prefix concatenated with the next sequence number wich is formatted to show two numeric places and a dash at the beginning.

GetNextSeq = sPrefix & Format(bSeq, "-00")

I am confused of which will check whether the record is there or no?

Can you post the code which will check the for record availability.
if the record there which coding adding +1

IrogSinta

If the record doesn't exist for that day, the DMax function will return a NULL value. Hence Nz(DMax("Right([ID],2)", "TableName", "[ID] LIKE '" & sPrefix & "*'"), 0) will become Nz(NULL, 0). The Nz function in this instance will default to 0 and since we always add 1 to the result, you will get a Sequence starting at 1 whenever the record doesn't exist.
