Modules & VBA :: Auto-Number Sequencing By Compacting The Database
May 30, 2014
Lets say you have a table with an AutoNumber field.You populate it with 100 records.You delete the last 10 records (91-100)Now, I certainly know you can refresh the AutoNumber sequencing by compacting the database so the next record entered is 91.
My question is about NOT refreshing the AutoNumber sequencing.Lets say you DO NOT COMPACT and DO NOT refresh the AutoNumber Sequence.So, in that scenario, after deleting records 91-100 from the table, is there any programmatic way to determine that the next actual AutoNumber for that table will be 101?

I have a RN generator that looks at 9 different lanes and puts in a number based off of a certain criteria but I was wondering if in the frmLanes the actual "Go" button was an incoming number how could I get my current random number generator to look at that number and determine if the current number is within 5 of the "go" number?
Any way to have a beginning number that I would enter into a text box and have the number generator kick off based off of that number. I have included a copy of my db for viewing.

I have a web database in access and I am trying to set up a new table. They key piece of this table needs to be a randomly generated ID number that is between 4-6 digits long. I know that when I set up a new table the ID field is set as "AutoNumber" but I can't seem to modify the properties of this field like I can in Non-web databases.
Is there a way to have a randomly generated ID number that is a specific length in a web database? If so, how can I do this (preferably without VBA since that is not Web compatible)?

Here is my issue. In a table with an Auto Number index some records have been deleted. I have been able to recreate them along with their original auto number. The problem is that I do not know how to append these records forcing the original auto number. I have tried changing the auto number field to a number field in the table, this works except I cannot change it back to auto number.
I am sure I’m not the first with this question or issue. I did search through a couple hundred entries about auto number before I posted this question.

Dear Friends
I have a .mdb password protected with all types of objects (tables, queries, forms, reports, codes, functions, modules, etc) they too are password protected in VB, the .mdb works fine but when I tried to repair and compact the database from the menu tools option, very recently it started giving me the message of database has been corrupted and requires tobe backedup before proceeding with the repair options and the log report of this corrupted .mdb file is to be sent to microsoft for the review.
In short i am not able to compact the Database though it works fine - but the moment I try to compact it gives me this problem - I am worried and concerned as its looks good but what happening in the background can anyone in here sugguest the remedy or the precautionary measures.
This file is on the network shared by min 2 person at the same time.
Please advice - thanks

Hello
I am aware that there are a lot of existing threads relating to compacting and repairing but I cant seem to find what I am looking for.
Basically, I developed a complaints database for my employers and it is used by around 45 people at any one time. The database was one of firt I built so it is not the best and is serious bloatware. Our server management team gave me an ear bashing the other day because the BE was 145MB. I did a compact and repair which took it to 45MB. The problem is that I need to do this daily but it involves kicking everyone out of their linked FE so the BE can be compacted/repaired. As an interim measure before I rebuild the whole thing I am going to schedule a database to open that will compact and repair the Complaints Database BE. Can anyone tell me the code to use to compact another database other than the one I am using. I have been looking at the code in other posts but I cant get it to work. The code I was looking at is the DBEngine.CompactDatabase... but I dont understand what comes after this and why??
Thanks people. :-)

I had someone write some code to access an Access database. The code works with the database as is, however if I choose to compact & repair the database to minimize its size, the code no longer works. What could be different about the database once it's been minimized using the database utilities?
Thanks,
Rick
P.S. Does compacting the database make it more responsive to users on the web that query the database, or doesn't it much matter?

I have a form that contains an autonumber field. Before any data is entered into the form that field displays the word "(Autonumber)".While it does this the subforms on my form that use that same field to run their querys are empty
Code:
Me.AllowAdditions = True
DoCmd.GoToRecord , , acNewRec
[Forms]![InvoiceForm]![CreateNewRecord] = True
Me.AllowAdditions = False
[CreateNewRecord] is just a invisible tickbox that is used to enter some data on the form; I don't want to use it but haven't found another solution.
Anyway. When the user opens the form they have to press this button Unless a new record was previously created and that's confusing. I'd like it in the form load event except I can't "see" the value of the field while it displays "(Autonumber)".My code for the form load is:
Code:
If InvoiceNumber.Value = Null Then
Command82_Click
End If
Where invoicenumber is the autonumber field and command82 is the new record button.

I have a form with a search box, Its UNBOUND called ID . Everytime I search for an ID number it shows no results, However I know there are entries in the table. This is the code I am using :
Code:
Private Sub ID_AfterUpdate()
If (ID & vbNullString) = vbNullString Then Exit Sub
Dim rs As DAO.Recordset
Set rs = Me.RecordsetClone
rs.FindFirst "[Id] LIKE ' " & ID & " ' "
[Code] ....
I am assuming I need to add something to search for auto numbers but i don't know what!

hi,
the following error message appears when trying to access my database. I can't seem to get into it at all, not even by trying to import the data tables over into a new database. the following message appears:
"The database has been converted from a prior version of Microsoft Access by using the DAO Compact Database method instead of Convert Database Command on the Tools Menu. This has left the database in a partially converted state. If you have a copy of the original format use the convert Database on the Tools menu to convert it. If the original database is no longer available, create a new database and import your tables and queries to preserve your data. Your other database applications can't be recorded''..
the copy and the back up wont let me in either, this just suddenly happened.
Please help!
Thanks in advance

I have a Ms Access split database where in the backend database grows up very fast and needs to be compressed everyday. I have written a batch script to compact the same and have scheduled it to be run every night. But the script is unable to compress the backend every time since the users tend to leave the application open at the end of the day. Ideally i am looking for a command line script to forcefully close the back end database if open before attempting to compact it.
I searched on web but could not find a command line script for forcefully closing the back end database.

I have a table (tblContact) with an auto number key field that is numbered sequentially (1-8) there are no deletions, each new record is appended.I wrote a simple FindFirst line to locate a record that is the first record in the table. The FindFirst failed to find the record.So, I wrote a Do Until Loop that cycles through each record looking for the record that I want to find (the first record with key field 1).
Code:
rstContact.MoveFirst
Debug.Print "ContactID: " & rstContact.Fields("ContactID")
Debug.Print "CEmployerID: " & rstContact.Fields("CEmployerID") & vbCrLf
Do Until rstContact.EOF
Debug.Print "ContactID: " & rstContact.Fields("ContactID")
Debug.Print "CEmployerID: " & rstContact.Fields("CEmployerID") & vbCrLf
This works to find the first record... eventually, because it does not begin its search at the first record. The results in the immediate window are below.
Code:
ContactID: 4
CEmployerID: 2
ContactID: 4
CEmployerID: 2
ContactID: 5
CEmployerID: 4
[code]...
I believe the field CEmployerID is unrelated to the issue. I am also attaching screen shots of the table "tblContact" and code with immediate window. I have tried indexing and not indexing the CEmployerID field in the Contact table to no avail. Even though the Do Until Loop eventually finds my record,

I have a form [IUDATA]
I have a add record button.
I have a date field [DATEIN]
I have a text field [DRPNO]
If the [DPRNO] field is empty, I would like the user to have the [DPRNO] field be automatically populated after the user enters a date.
I'd like the format of [DPRNO] to be "dpr YY-XXX"
Where:
YY is the year of the [DATEIN] field and
XXX is number of records in that year.
So for example, if it was the 4th record with a 2013 date the [DPRNO] would be dpr 13-004.

Hi,
I'm trying to get the maximum number in a table field to increase it by one depending on the member that is selected in a drop down in a field.
I have three tables: members, programs and times. Each member can have N programs and each program can be broadcast N times.
Each member has a three digit code, like XXX. Each program has the three digit code of the member + three numbers that are supposed to auto increment. That is, the first program of member X with the member code XXX is called XXX001.
What I'm trying to do is that when a new program is filled in and I select the member, then the program code should update automatically, adding one to the latest program by that member.
That is, if the last program by member X that was inserted in the database is XXX010, then if a new program is inserted it should automatically be XXX011, even though programs by other members have been added in between.
This is the code I use now, for the AfterUpdate when selecting the member in a dropdown in the form. But although I've played around a bit, I just get error messages...
Private Sub medlemsruta_AfterUpdate()
Dim medlemskod
medlemskod = Me![medlemsruta].Column(2)
Dim strMax As String
strMax = DMax("programs_kod", "table_programs", "Left$(programs_kod, 3) = medlemskod")
Me!program_kod = Left$(strMax, 3) & Format$(Val(Right$(strMax, 3)) + 1, "000")
End Sub
Medlemsruta is a dropdown where one selects the member from the members table, where the three digit code is in the third column (Column(2)).
I'm trying to use DMax to get the maximum number for the particular member and after that adding 1 to that for the new program code.
Grateful for any advice! Thanks!

I need to first generate a random number between 1-4.
Then I would like to use that number to pull that many records out of the database; the records pulled can be random, or whatever.
For example, we have 4 people and my goal is to choose a random # of records to pull for each person. So, for person #1, it might only pull 1 record, then for person #3, it may pull 2 records, etc.
Ideally, it wouldn't pull the same # twice when run for that "session".
After this, I'm hoping to generate all those results into emails (eg for person 3 it would generate 3 emails, etc)
Currently it's all done manually and I think it's doable with Access.
I have some code already for generating "1" email message, but do not know how to pull X number of emails all at once. (X is the random #).

I have a table in a database with 7 columns. The data is sorted by Date1 in descending order.
For each pid I want to put the sequence numbers
First record has two conditions
If string 2 is null then start numbering from sequence1
If string 2 is not null then start numbering from sequence2
If string 2 = string1 then
Sequence1 = 0
Second record has two conditions
Number sequence2 with the value 2 or 3 depending on the line one
If string 2 = string1 then
Sequence1 = 0
Else
Sequence1 = next number
Same condition for the rest of records

Well, here's my database :
Name : String
Address : String
I want to add an automatically generated column, "no.", to show which number it's in. Like this :
No. Name Address
1. A Unknown
2. B Unknown2
The problem is, I can do that with Auto-Number, but if the user delete row 1, the number in row 2 is still 2, not 1.
Is it possible to generate query that have "no." column in it ?

I have a table with an auto number PK. This table will contain orders. I'd like to use the PK from this table as the Invoice number on the invoice. I'd like to have it start at a number other than "1" just because it looks better on an invoice. I don't know how to do this. I looked at the table design to see if there were options available to me there but couldn't find anything. Is it possible? (I do not know how to use code.)

We have a database that is split. Every user has their own front end (installed via a .bat file so that the users always have a local copy of the most recent version), linked to a shared back end on a server. This seems stable and functional for us so far.
However, because our users are geographically separated, I don't actually know how many folks are using the database. I know the folks who contact me, but everyone in our company could use it if they wanted to.
For requesting funding, guiding future development, etc., I need to get some metrics:
Total number of unique users
Avg uses per day
Total number of simultaneous users (daily, weekly, and monthly maxes and mins)
What is the best way to get this info? Write user info and a timestamp to a table each time a front end is launched? Are there tools for monitoring this sort of information?
