Bounded And Translated Custom Autonumber
Nov 2, 2005
I was hoping to run this by you guys to see if I'm doing anything horribly wrong. I have done a number of searches related to custom Autonumbers and I think this is okay but any suggestions/confirmations would be greatly appreciated.
I want to create a random Primary Key that will also be used as an item #. I know that in many cases this is frowned upon *but* I do not need the number to hold any significance I just want it to be unique. However I want to represent the item # as a set of 6 Hex digits so the standard Long Integer is too large. 16^6 = 16777216. No 0 index so 16777215.
I create my own bounded number with a macro (=Int(Rand(16777216-1))+1 )and put that as the default value. It is indexed and set to no duplicates. Is this correct?
When I display the field in a form or report I call a module which translates the number into Hex and appends leading zeros. I am currently having a problem where inserting a new record does not display the translated index correctly, but after it has been inserted it is fine.
If you have any comments or suggestions about how this could work even better (or if this wont work at all!) please let me know.

I am in the process of developing a DB for work. The DB is used to track incident reports and lost/found property reports.
I was interested in using 2 custom autonumbers for 2 different reports within the same DB. I would like to use the format of "I" for an incident report, "F" for the found property reports. So when I start a new Incident report it would generate the following number; "I05-03-001" The "I" specifing that it is an incident report, "05" for the current year, "03" for the current month, and "001 as the next sequential number for the reports for that month.
Does anyone have any suggestions on how I can get this done? I would very much appreciate your help.

I currently have a few tables that use an autonumber as the primary key, however, I would like the autonumber to start with a series of letters if possible. For example: instead of it creating an ID of 1, then, 2, 3, 4, and so on, I would like it to append lets say "ABC" to the front of it; ABC1, ABC2, ABC3, etc.

Just a general question...
When you make a primary key is it better to use and Autonumber or a Custom one? I have for the most part used auto...easy, convienient and well I have never had a problem yet (been pretty serious on Access for about 1 year). But I just read that ref integ doesn't work on Autonumbers? which would also mean cascading update & deleting correct?
I have looked at Northwind Access sample and all except "Customer" they use Auto. Well then to make a custom Primary field wouldn't I have to do that at the form level? like "CustomPrimKey = Left([CustFirstName],2 & Left([CustLastName],2) & [PriKeySetAtAutoNum]" or something like that to get what I want. I imagine you would automate this as opposed to letting the operator manually enter them.
And then as in the Northwind sample how do you know which tables need the custom numbering and which ones don't.
As I have learned on my own some of the "basics" elude me until they come back to bite me.
Thanks

Custom Autonumber based on lookup. I am creating an access database where autonumbers to be work.
I have a table with Segment Name my main table will lookup the values of segment table.
Based on the Segment I choose Autonumber has to be created
My main table to house each record (tbl_import) has the following fields:
ID
Segment
Port
MOT
TOTAL CIF
Child table - Segment contains
Development
Deployment
Testing
So based on segment field which I choose
Development autonumber has to set DEV-1001 and Deployment has to set DEP-2001, TEST-3001
My thought is if there a way to code the Segment field to lookup the segment what I choose based on the Autonumber series starts (similar to a vlookup in excel), then concatenate the DEV in the Record ID field.

I need to create an "autonumber" field in the following format:
FYYMMXX
Where F is a constant, YY is the year, MM is the month, and XX is an incremented number. So for example, the first record in August of 2013 would be "F130801".
I've been checking other threads but haven't been able to follow them to a resolution. I think there is a way to do this within my form...

I have an excel file linked to a table in Access. Several fields are date data types in excel but are showing up as text fields in Access.
My real goal is to do a comparison between two tables, but only if the date of the one piece of data is newer than the other. I had planned on comparing the two date fields but even though I have formatted the date fields in my excel file to be "Date", when I look at the design view of my table it is showing up as "Text" and therefore I am unable to do this comparison.
I'm not sure if it's just something that I'm missing but maybe someone else knows an easy fix to this. I know this is probably a simple question, but I did search the forum and didn't find a thread that specifically dealt with this issue.
Thanks in advance for your help.

Hi everybody .I created a bounded form that allows user to enter the following fields information
to the sql server db that is linked to access .The fields are: Projectno, taskcode, taskdiscription
and total hours worked.
I want for example when a user tries to enter total hours work for a user (Hours in hours worked table) and
if he did not already enter wages of the employee for that particular project (amount in hourly wages table)
that user get a massage prompt and ask user to enter amount in to hourly wages table first. Possibly opening that form.
I be happy if some one help me add this feature to my form. Thanks

I have:
1) a table (T) with fields (F1, F2, .... , Fk, .... Fn). I do not know "n"
2) a form (F) bounded to this table
I know that I have a control bounded to field Fk.
How I can find what control is ?
Something like this:
Dim MyCtl As Control
Dim ctl As Control
For Each ctl In Controls
If ctl IsBoundedToFieldFk Then
Set MyCtl = ctl
Exit For
End If
Next ctl

Access 2007
In a table I have 2 fields:
D1 , Date/Time , DefaultValue: Date()
D2 , Date/Time , DefaultValue: Date()+1
In a form (bounded to this table) I have, of course, 2 controls bounded to this fields:
txtD1 and txtD2
If the user change the value in txtD1 (using the Date picker) I like to change the DefaultValue for txtD1 to the new date and the DefaultValue for txtD2 to the new date + 1 day. Something like this:
Code:
Private Sub txtD1_AfterUpdate()
Me.txtD1.DefaultValue = Me.txtD1
Me.txtD2.DefaultValue = Me.txtD1 + 1 day
End Sub
I tried whatever crossed my mind... with the same "result" : #Name?
My Regional settings:
Short date format: dd.MM.yyyy
Date separator: Dot
Simple: 05.12.2013

I have two tables linked to each other in one to many relationship. Instead of auto number, the date and shift (Text) is being used as the primary keys (Composite Primary Key). Here is the tables structures,
Payouts Table:
Date: Primary Key
Shift (Day or Night) : Primary Key
Bills Table:
Date: Primary Key
Shift (Day or Night): Primary Key
Autonumber: Primary Key
The tables Payouts and Bills has one to many relationship. One payout row can have many bills. The problem is that I want to start the Autonumber in bills table everyday from 1. As date and shift are different for every day so even if i start bills from 1 everyday, it wont make same primary key. I can do it manually but I want to make it automatically.

HI all, I have recently created my own custom toolbar for my database which works fine on my computer, but when the database is transfered to another computer via a memory stick (needs to be done as it is going to be used on remote laptops away from the main network), the custom toolbar does not carry over. Instead of the custom toolbar being shown, the normal, main toolbars are reset to the default ones shown.
Is there a way of stopping the toolbars reseting when transfering the database so that my custom toolbar is the default toolbar?
Thanks for the help!

I have a custom toolbar in my application. However, it isn't visible at the top of the application window and when I try to make it so - via View - Toolbars - it doesn't appear on the list of available bars.
I had assumed that I had somehow deleted it, but I know it's still present somewhere, as when I try to recreate it, I get a message saying so.
How can I get the toolbar to be displayed? :confused:

Hi folks:
when I create a custom toolbar on my db, would that custom toolbar be carried to other copies of my db? I'm hiding all toolbars using code and I need to display only one.

Hello, I am trying to set up a relatively simple relationship between numeric fields in two (already related) tables. The problem is Access doesn't really support this type of relationship... or in fact, doesn't have an interface for coding your own custom relationships (if it had one, this would be ridiculously easy).
But it doesn't. So I have to turn to you.
To explain my problem better, I'll use a visual aid.
http://img269.imageshack.us/img269/9123/db1zx2.jpg
My two tables are as follows, the master is called [Raw Materials] and details is called [Raw Materials Details] (the aptly named).
I guess I should rename the [Raw Materials].[Stock] to something else (as this isn't REALLY data redundancy). But anyway, what I want to do is have the [Raw Materials].[Stock] automatically equal to Sum(Stock) FROM [Raw Materials Details].[Stock]. To rephrase, I want the Total Stock field to be automatically equal the sum of corresponding stocks.
Either way, I have no idea how to go about doing this. Can anyone point me in the right direction?

Hi all,
I cant make work, a query with creteria filled within controls of a form. I will be more specific to make u understand what i want to ask.
There are 2 text fields and 2 combo boxes. All of them call a report (by pressing a button) from the main table.
in the "totalquery" query i call each control this way:
select tblPeople.name,tblPeople.tel,tblPeople.age,tblPeop le.Car from tblPeople where tblPeople.Name=[forms]![frmMyform]![combo1] OR tblPeople.tel=[forms]![frmMyform]![text1field] OR tblPeople.age=[forms]![frmMyform]![text2field] OR tblPeople.Car=[forms]![frmMyform]![combo2]
GROUP BY tblPeople.name,tblPeople.tel,tblPeople.age,tblPeop le.Car;
I want to make it display (the right) results if one of the text filed/combo is filled or with data, or all together or in combinations.
i use the OR statement,but it doesnt work if I fill in two fields/combos together and etc.
Anyone? :rolleyes:

Hello all!
Basically what I am wanting to know is how difficult is it going to be to do the following.
I want to have 8 searchable fields, first name, last name, MO, Job code, etc etc. I want to be able to type somthing in any one of these fields and then when i hit a submit button I want to to return to me all the data that corresponds to what I am looking for. I know I could just create a simple query from the query wizard but i want everything in the program to look uniform as to not throw every one off. How difficult would this be and how should I go about doing it. If you need more information let me know.
