Access, Required Fields, Forms & ODBC
Jan 28, 2008
I am working on an Access 2002 database where one of the tables has five required fields making up the key.
There is a form that is linked to this table which is used for adding new records.
There is a close button on this form that has the following code in it's OnClose event:
"DoCmd.close"
When the form is opened, no data entered and then the close button is clicked - nothing happens.
It used to work fine, until I recently upsized the database into a SQL Server database and now it's all gone horribly wrong.
If I close the form manually by clicking on the cross, I get this
error:
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value
NULL into column 'Product', table
'LeasebookSQL.leasebook_user.leases'; column does not allow nulls. INSERT fails. (#515) [Microsoft][ODBC SQL Server Driver][SQL Server] The statement has been terminated. (#3621)
Can anyone please tell me how I can get the form to close without trying to save the record, especially when no changes have been made to the data on the form?
Thanks,
Simon

I have made a form based on related tables. it requires me to fill out every field, which I don't want. I didn't make them required. Why does it do that?

Hi, I have created a File DSN using my ODBC under Admin Tools and placed it on the network and have linked my Access 2003 tables to point at this.
I have asked a non-domain user to log into this database and open a table but when they do, it defaults to a Domain account until you untick trusted Source. You then have to enter the username and password for the ODBC connection. I thought the whole point of a File DSN was to eradicate the process of logging in. Can anyone Help?? Thanks
This is what the ODBC looks like through text editing software.:eek:
[ODBC]
DRIVER=SQL Server
UID=MyUserAccountName
LANGUAGE=us_english
DATABASE=MyDatabaseName
WSID=MyWorkstationName
APP=Microsoft Data Access Components
SERVER=MyServerName
Description=MyDescription

I have a form and subform.The form and subform both access tables that have "required" fields.If I try to tab to the sub form without filling in the required field then I get an error message generated by access (this is what I want). If I try and exit the form without the required field I get an error message as well.
Now it's a different story with the sub form. The sub form contains 1 to many rows. In each row there is a required field. I don't get any error message for not filling in that field. I Know I can 'capture' this in the code but I want access to do it.

I Created a form and linked it to a ODBC table with no data. Set the Allow Additions property to Yes. It shows fine if there is data in the table but not when there is no data.

I tried to check if all required fields have been filled before saving the record using the following code.
Private Sub txtReportNo_BeforeUpdate(Cancel As Integer)
If IsNull(Me.cboMainCat) Then
Cancel = True
MsgBox ("Please enter Data for Main Cat")
Me.cboMainCat.SetFocus
End If
Repeat above code for all required controls here.
End Sub
It did not work with following error code.
Run-time error 2108
You must save the field before you execute the GoToControl action, the GoToControl method, or the SetFocus method.
The error message contradicts my original intention that prevents from saving without all required fields have been filled. Is there any way to get rid of this error message?
In addition, under the value of certain field, I need to check additional fields under that scenario. Is any additional code required to add in for that purpose?

I have a transaction form and there is at least two fields I need to make sure have been entered before the record is saved.
I have no problem with text or numeric fields but I can't seem to be able to check the contents of a drop down field.
What is the best method to use to make sure a drop down has been selected by the user and contains a value.
I have temporarily used a default value in the drop down but that's not really what I want.

I need code that I can incorporate with the code below, that will notify a user when required fields are left blank so that they have to go back and fill it in before updating the record. Below are the objects (shown in the order they appear on the form):
cmbModel
txtSerialNo
txtExpDate
txtPONo
cmbOfficeLoc
If any of the objects above are empty, the user should be prompted to go back and fill them in setting the focus back to the first empty object (again the fields above are in order). If conditions are not met, do not run the code below. If the conditions are met then proceed with the code below.
Private Sub Form_BeforeUpdate(Cancel As Integer)
Dim strMsg As String
Dim iResponse As Integer
' Specify the message to display.
strMsg = "Do you wish to save the changes?" & Chr(10)
strMsg = strMsg & "Click Yes to Save or No to Discard changes."
[Code] ......

I am using code like this to give warning messages and pass on focus to boxes only when things are selected.
Private Sub TextBox2_Exit(Cancel As Integer)
If IsNull(Me.TextBox2) Then
MsgBox "TextBox2 cannot be left blank"
Cancel = True
Else
ComboBox1.SetFocus
End If
End Sub
I do this for a series of required fields in order.
However, I also want a command button that is 'Exit without Saving' that should be clickable at any time, but of course when focus is controlled in my required fields sequence, it can't be clicked. How can I separate this button?

I created this function to manage a MsgBox containing all required fields with no data:
Code:
Function FormValidation(TheForm As Form) As Boolean
Dim boolResponse As Boolean
Dim strError As Variant
Dim ctl As Control
boolResponse = True
strError = Null
[code]...
Then, I have a Form_BeforeUpdate event, where I wanna place the function, which contains also some VBA code to manage duplicates records:
Code:
Private Sub Form_BeforeUpdate(Cancel As Integer)
Dim rst As DAO.Recordset, dbs As DAO.Database, strICAO As String
Dim ctl As Control, txtMsg As String
[code]....
Now, how to add the function in this event to get these two results:
1. if required fields are blank and I press OK on the MsgBox, the routine must stop;
2. the focus must go in the first required blank control.
I tried some options but I get different kind of malfunctions: no custom message for duplicate records but only the access default one, "go to next record" feature with tab key not working and so on.

I'm having problems with the required field option in my table. I have a form that writes to the table and has a validation of the fields built in the code. If the validation is true, then it will allow the record to be saved.
However, I've also set those same fields in the table to be a required field. Whenever I enter data in those fields in the form and click the save command button, I get a message back telling me one of the required fields cannot be null. The thing is, it is not null. I entered data into the field through the form. Whenever I change the required field option to no in the table the problem goes away, but shows up on the very next field in the list that is set to yes.
Validation occurs within the form that writes to the table, but I still would like to have the security of knowing the fields are required in the table as well, just in case someone tries to be sneaky and go directly into the table to enter/modify data.
Is there something I'm missing? Is this a bug? I've actually set up another database the same way and don't have any problems with it. I'm not sure what's going on. Has anyone else had this problem?
Thanks,

Is there any way that you can have required fields in a form, but access will not look for the required fields until you try to exit the form. Basically; i have a form that users keep track of there work hours on specific parts. they leave the form minimized for most of the day. After they enter a record, they sometimes need to go back and edit a previous record, only they are on a new record and access will not let them go to a previous record unless they have the record fields entered.

Well guys, I don't know if this is possible or not, but maybe someone can guide me in the right path.
I have a data entry form that several employees use. I have certain required fields that are set on the form level. I have couple employees that I would like to have the ability to override these fields. I was thinking like using F10 key or other key combinations that will allow them to override the required fields in order to save the record.
Is this something realistic that I can accomplish in access, and if so, does anyone have a sample that can help me with this task? Thanks to all.

I have a form that I want to make all fields required so that the user cannot leave that form until all fields are filled out. I have the Required property in the table set to yes, and this works fine if I go to the form from the database window. However, If I go to the form from the main switchboard (In Add Mode), the form can be closed without all of the fields being completed. I know it's probably something pretty simple, but I haven't been able to figure it out. Any help would be greatly appreciated. Attached is a picture of the form if it would help at all.

Hi,
I have a main form with one subform (Datasheet view). On the main form, I have an On-Click Event button (“Save and Close”) which sets required fields on both the main form and the subform before saving the record.
Here is the problem:
- I start by entering some data in the main form
- I then tab into the subform and enter data
- I then tab out of the subform back into the main form – this is where the problem begins: When I enter all available data in the subform, including satisfying the required fields, and tab out of the subform back into the main form, the subform seems to initiate an extra new record – so… upon clicking the “Save and Close” event button on the main form, the event looks for the required fields of the blank subform record to be populated (a record that I do not have any data for). I also noticed that this required field notification in the subform can be satisifed by simply populating more fields in a previous subform record???)
I have tried a few things to resolve this and have looked throughout this forum without any luck – hope I didn’t miss something.
Any help would be appreciated. I have attached a very simplified version of my database.

Hi.
I have a form with 3 fields that are required, the other fields within the form are not.
Is it possible to make it so the non-required fields are only selectable/editable once the required fields are filled in? And if they are selected, a message appears saying "please edit required field first" or something like that?
Thanks for reading
Frank.

Hi all,
I have split a database, then realised that I needed to change two fields in a form. Y/N field and Text field.
I went into the backed database changed the fields to be Required but in the front end it doesn't seem to work? I haven't tried re-linking them but should I need to?
thanks

Hi,
I have created a form with 3 subforms. This form is split in to 3 parts on a 3-page tab control.
I want the user to enter data in the order below. All fields are required. My problem is that Access97 wants all fields of the main form to be completed in the order set by the table. ie. before I fill in a sub form. I have tried setting the form tab order property but it is being overridden.
First page:
a) Complete first 6 fields of main form
b) Complete subform 1
c) Complete subform 2
Second page:
d) Complete 5th field of main form
e) Complete subform 3
f) Complete 6th field of main form
Third page
g) Complete three fields of main form
Any help appreciated,
Seth

Hi all, I've searched this with no success.
I have a ODBC (Firebird) table linked using a DSN connection which has >300 fields. In Access, the linked table only show 256 fields (max for Access). Otherwise the link works fine. I have no control over the source Firebird table.
What I'd like to do is limit which fields from the Firebird table are shown in Access. I don't need all the fields, but I need some that are at the end and are not linked in the current setup.
I'm very much a novice at using ODBC, but can I somehow use SQL or some other method to specify which fields to show in the linked table?
Thanks for any suggestions,
John

One form. Several fields which are required using event 'On exit' - "If isnull" statements for each one.
Button on form to close said form...
Where on the form would I put the event for the button to override all other events?

I am having a problem with an access database that is connecting to a sql server. When trying to run any queries it is very slow. I think the problem might be caused by the ODBC link and I was wondering if there are any alternatives to using ODBC to connect access and sql.

Hello all, is there a way to change an ODBC connection in MS Access. I have 4 ODBC connections that I can choose from (all of them from the same server), and instead of manually recreating a new ODBC connection everytime, I would like to point it to the new connection. The ODBC connections (Tables) have the same information, but throughout different times during the month.
Thanks in advance for your help.
