Displaying Primary Key Not Text

Sep 19, 2011

I am a new Access user. The problem I am having is getting the data in a subform to display the text associated with the primary key rather than the primary key itself. In the subform StudentEnrolmentTable, faculty choose the CourseNumber from a combo box and the remaining associated fields are populated with and update query. The problem is when the associated fields are viewed by faculy through the form, they are showing only primary keys and not the text the key is associated with.

Text Box Message Not Displaying

Apr 3, 2008

Hi I wonder if someone can help me with this.

I have an access database in which there are tab controls to collect text written about a subject. My problem is that there are nine tabs all with the exact same code behind them, but obviously varying object names for the relevant text boxes. Four of them work as expected and five don't.

The following code has been used to display a popup if the user types too much text and it works for the Environ_Plan text box:

Private Sub txtENVIRON_PLAN_Change()
Dim strMessage As String, varLen As Variant

varLen = Nz(Len(Me.txtENVIRON_PLAN.Text), 0)
If varLen > 250 Then

strMessage = "You have exceeded the limit of this field by " & (varLen - 250) & " characters." & vbNewLine
strMessage = strMessage & "The maximum allowable length is " & 250 & " characters."
MsgBox strMessage, vbOKOnly + vbExclamation

End If
End Sub

(note that if the user types 251 characters an error message appears on the screen to say they have exceeded the number of characters allowed for that box and they cannot type any more text.)

The following text is used for the exact same outcome in Health but it does not work:

Private Sub txtHEALTH_PLAN_Change()
Dim strMessage As String, varLen As Variant

varLen = Nz(Len(Me.txtHEALTH_PLAN.Text), 0)
If varLen > 250 Then

strMessage = "You have exceeded the limit of this field by " & (varLen - 250) & " characters." & vbNewLine
strMessage = strMessage & "The maximum allowable length is " & 250 & " characters."
MsgBox strMessage, vbOKOnly + vbExclamation

End If
End Sub

(In this case the cursor stops and the user cannot type any more text but no message appears to say why the cursor has stopped.)

I have double checked the actual variables in the Access database and they are set to the exact same values.

I am using Access 2002 on Windows XP Professional.

thank you in anticipation.

Tables :: Text As Primary Key Vs Auto Number

Jun 19, 2013

When I first was making my database I used all auto numbers for PK's. But then I read an article or two saying that you really don't need to do that if you don't have to (actually, the article said "don't use autonumber if you want anyone to understand your database). I have a few tables (most employee experience type tables) where I just use the word as the PK and there is no auto number in the table at all.I continue to build my database?

Displaying Aggregate Info About Query In Text Box

Feb 5, 2013

I working with Access 2010 and a form with criteria controls, a requery button and a subform that displays the query. I wanted to add a text box that would display some aggregate information about the query results. Like how many results were returned or what the average is in a column of numbers stuff like that.

If at all possible I was hoping to have the text box display aggregate information of the whole query but when a specific entry in the table is clicked I was hoping to have it show aggregate detailed information about that entry opposed to the whole table. So I am not sure if that changes the solution but I wanted to put it out there.In my searches it looks like Dlookup is the way to go but I have seen a lot of people use Dlookup in very different ways so I might be wrong.

Tables :: Want To Export Data As A Table But Displaying Text Value Rather Than Key Value

Oct 26, 2013

I have inherited 1000 records which need to fit into new criteria selected from combo boxes and to do this individually by the forms will take forever so i want to copy and paste the data in the table, but when I do it doesn't fill in the form.

This may be a problem with the cascading script in the form as the fields fill in when I press f9 but disappear every time I open the form.Finally I eventually want to export the data as a table but displaying the text value rather than the key value.

Queries :: Inventory Database - Displaying Results Of Query In Form Text Boxes

Aug 7, 2015

I have a Inventory DB and i want to integrate scanning. So far i have a table called StockInfo, this table holds information about bar codes (device type, make, model). I have a form called Scan_Barcode, on this form I want to be able to scan a bar code into a text box (text0) and use a afterupdate and requery function to display the results onto a form called EnterInventory.

Not only just the results but I want certain columns from the query to display in certain text boxes on this form. I have a query called FindProduct. that filters the criteria by whats entered on the Scan_Barcode text box (text0). So when i scan a certain bar code i can get the query to display certain product information for the bar code. I just cant get the results onto the HarwareStock form.

Primary Key No Longer Primary Key!

Sep 15, 2006

I have created a very simple Access database with a CompaniesTbl, ContactsTbl and CallsTbl. The database is used to record telesales contact with customers. The tables are set up like this:

The CompaniesTbl has an AutoNumber Primary Key field called CompanyID.

The ContactsTbl has an AutoNumber Primary Key field called ContactID and a foreign key called CompanyID.

The CallsTbl has an AutoNumber Primary Key field called CallID and foreign key called ContactID.

The relationships are set up in the relationships window and referential integrity imposed.

Twice now, while editing a contact record, an error has occured. Task Manager has had to be used to get out of it. The error is either a 'run-time error with a message that does not mean anything' or it says 'unrecognized database format' (!?).

If you open the database again the ContactID field in the Contacts Table is no longer a Primary Key field. If you look in the relationships window - the relationship between the Companies and Contacts tables no longer exists.

Any ideas much appreciated.

Primary Key

Feb 27, 2005

Hello

I have a problem with a primary key. A table called relaties has a column relatienumber with date type: number, which is also the primary key. When a button is pressed, a function searches info from the table relaties.
The problem is the following: I figured out that when i remove the primary key constraint from the column relatienumber and save the table. the function doesn't work anymore, also when i remake the primary key for this column. How is this possible, because i changed nothing futher.

This is important because i want to change to access db to mssql db and in mssql the function also doesn't work.

It has something to do with this primary key constraint, i think :)

Who has the info???

Primary Key

May 30, 2006

when defining tables, i normally set an autonumber as a primary key. However, i am working on a particular table, and i would like that no record will have identical values, in three particular fields

aaa bbb 123
aaa ccc 234
ddd fff 555
aaa bbb 123 <- i want to prevent this since a record with those three values already exists

Shall i set these three fields together as a primary key, or can i leave the autonumber as primary key and prevent such duplication in any manner ?

Thank You

Primary Key

Oct 15, 2007

Can a PK be a calculated field?

I want to be able create a PK that consists of three strings being added together. The first two would be collected from cascading combo boxes. The third field is a simple text field.

I would then run DLookup to make sure the final string is unique.

I have reasons for not using an autonumber field (there are compatibility issues with existing tables from a much older dbase database).

Primary Key - PLEASE HELP

Sep 10, 2006

I have a database that I got up and running but one problem. I have as the primary key a social security number, but I can't seem to be able to add additional information to the same person. All I can seem to do is just replace or edit the one record. Is there a way that I can have more then one order for an individual instead of taking the primary key off of social security numbers?

Do I need a seperate form to enter information because I am currently workin with one form where I can enter and edit the information but no duplicates so lets say if my social was 099-999-9999 I can't add an additional order it seem unl.ess I make a whole new record and make a dummy number...

Displaying One To Many To Many

Feb 21, 2007

Hello!

I have been struggling with this problem for a while and I'm so deep into it I can't look at it clearly anymore. I hope someone can give me some advice.

I'm trying to set up an orders database, but instead of one "product" I have a service with many specifications. One service part can have many kinds of inspections, which in turn have many inspection criteria.

That part seems okay to me, I guess. There's a one to many relationship between services and inspections, and a one to many between inspections and criteria. The problem is displaying that in a form in a way that's not confusing to the users - I can't put all that info in one line, and I can't put subforms in continuous forms, the best I can come up with is to have separate subforms that display the inspection types when the part number is selected and the inspection criteria when the types are selected. The users I tested it on are totally confused about it. What's the best way to go about displaying it?

I secretly just want it to look like this!

PartNumber Service Criteria Price
1001 Gauging (for) Length $100000!
(for) Diameter
Sorting (for) Rust
2222 Sorting (for) Rust $10

Maybe that's just as confusing. A fresh perspective would help.

This forum has been such a wonderful resource to me and I've learned a lot. I feel kind of embarrassed posting because I know my questions are access-ignorant, but I'm really having trouble figuring this one out on my own. Thanks for any ideas.

Configuring Primary Key

Nov 21, 2005

I have a tblState, every state can have multiple Counties, and every County can have multiple Municipalities
This should be a One to Many to Many, right????

However, several states might have the same County name

In order to resolve this, should I add 2 primary Keys in the tblCounty????

If so, I already tried and couldn�t configure it.

I have attached a sample DB
You can open the relationship view for a better explanation

I appreciate any kind of support

Thank you
Joe
