Before Update Validation
May 24, 2005
I've read numerous posts and I'm still not getting this. I have a form with 3 required fields: Supplier, name and PartNumber. I want the code to let the user be able to go back and fill in the field so I put the setfocus there - but instead the access message interupts and doesn't allow the correction. Then it states that can't save a record at this time (bla, bla). Could someone please look at what I have and assist me in making the form validation as well as allowing the user the chance to fix the mistakes:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Name) or me.name =””Then
MsgBox "Required Name", vbCritical + vbOKOnly + vbDefaultButton1, "Missing Data"
Me![ Name].SetFocus
ElseIf IsNull(Part_Number) or Part_Number = “” then
MsgBox "Required P/N", vbCritical + vbOKOnly + vbDefaultButton1, "Missing Data"
Me![Part_Number].SetFocus
ElseIf IsNull(Supplier) or Supplier = “” then
MsgBox "Required Supplier", vbCritical + vbOKOnly + vbDefaultButton1, "Missing Data"
Me![Supplier].SetFocus
Else
Cancel = True
End if
End sub

I'm working on a code that checks all blank/null text fields and combo boxes in a form and notifies the user if a field is not filled. The code below works if all fields are required, but I can't use it on forms that have fields that are not really mandatory. I've read somewhere on the net to use tags on the controls i want to skip checking, but that's where i get lost.
Code:
Dim stdResponse As Variant
Dim ctl As Control
' Enumerate Controls collection.
For Each ctl In Me.Controls
' Check to see if control is text box
[Code] .....

My membership database has worked fine until recently. Now I cannot save inserted data. On attempted saving "Update or CancelUpdate without AddNew or Edit" appears.
The problem. relates to 2 tables Member and Addresses. PK in the parent table Member is ID. In the Addresses Table the FK is ID. There is a One to One relation between the tables and Referential Integrity is set. I know 1 to 1 is not good but it worked fine in this small database.
Browsing the all of the existing records is fine.

How would i go about setting the validation - if Damage To Property is data type "No", disable the "Damage Comments" field. (ie grey it out).
any help would be greatly appreciated..

Hey peeps,
I have a problem. I want my field to become "[field], An " etc. when I type "An [field]" For example, if I type "The Hundred Years War" for the field, it automatically updates to "Hundred Years War, The". I would be happy with a simple validation rule that prohibits the use of "The, A or An" in the beginning of the field but i don't think that is posibble. If this requires VB, I don't know how to use the language and never worked with it. I am completely a novice in VB, but would still love to learn how to make it. :) If you could start me out then, I would appreciate it greatly. :D

Hi im new round here but am working on a database and sum of the validation rules are confusing me now.
Ok i got a couple of things to ask:
1) What rule do i use to make sure only text is entered into the field, i cant use input masks as the size of the text put into the field will vary, as its names of people.
2) Is there a way to check that all the fields on a form have been entered? So if there not all entered an error appears?
3) Finally, is there a way to reset Autonumbers? or do i have to delete all the records and start frm scratch as my autonumbers have gone abiit crazy as sum records have been deleted so my table looks rather strange.
Thank you, help greatly appreciated :)

Hello,
For my Year 12 Computing course, I need to develop a database which will take bookings for a village hall. The database consists of a Bookings Table, a Customer Data Table and a Hiring Cost Table. It is in the Bookings Table that I am having the most trouble.
I believe I have already solved my double booking dilemma by making the Date of Event and Type of Event fields in the Bookings Table into a composite key, thereby prohibiting the entering of data where Date of Event and Type of Event are the same, making them unique.
Here is my main problem at the moment, I need a validation rule on the Date of Event or perhaps the Date of Booking field which means a booking must be made at least a week, and no more than two months in advance of the date of event. The thing is this validation rule is only needed for occasional bookings. Present, again on the bookings table is a Booking Type field which has a lookup consisting of the following “Regular” and “Occasional”, regular meaning bookings that are made at the start of the year, for the whole year.
Ideally, I would like to have it so that when the booking type field is set to regular, the validation rule for the date isn’t needed, and when the booking type field is set to occasional, the validation rule for the date is needed/present.
Could anyone help me with this? As any help would be much appreciated.
Many thanks
Daniel
If anyone would like any screenshots of the Bookings Table, email me at daniel_goodman@hotmail.com

How can I set validation for a text field where I restrict the number of characters? For example, if I only want the user to be able to input 12 characters or less, and more than one. >=1 And <=12 would that be correct?

Hi all, Very new to using ACCESS. I am trying to set a validation criteria to ensure that a postcode is imported correctly. An example of a UK post code is SP10 3PB - it may be entered as SP103PB. I need to set a validation criteria to allow either two. What is the format of the criteria to achieve this? Any clues please. Thanks Mike
Are there any useful sites that set out examples of validation criteria?

On the coaches table we have a combo box which has all the different qualifications in it, we have 5 of these boxes but we want to it so that when one has been entered it cannot be repeated in the other boxes, also we want it so that when level 4 Tennis has been entered - levels 3,2 and 1 cannot be entered.
Any help on this would be great,

Hi Guys,
I need to set validation rule on a field. I have done the the below:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Me.SlideType) Then
MsgBox "You have not entered SlideType!", vbExclamation + vbRetryCancel, "Incomplete Form!"
Cancel = True
Me.SlideType.SetFocus
End If
It works fine, but I cant get it ignore it if I press cancel. Sometimes this data is not available so it has to stay empty. When I press retry it should take me to that field to make changes and with the cancel click it should allow me continue with the last command/action before the msgbox was brought up. Can anyone please help, thanks.

Hi,
i have a form that requires validation. i am using the following code:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Me.number) Then
MsgBox "number is required", vbOKOnly
Cancel = True
Me.number.SetFocus
End If
i have repeated the above code for other fields.........
The problem i have is, if i click 'x' and before it allows me to exit, it brings up the validations, one by one (so annoying).
Is there any way THAT it can show all the validations at once??? in one message????
THANKS

hi all
The following code isn't working
If Me.txtScore > Me.txtMaxScore Then
MsgBox "Outside score range"
DoCmd.CancelEvent
I'm using an ADO unbound form to add records.
the txtMaxScores comes from a data table with its properties set as text. (I've tried using number but I can't get that working either)
The txtScore is an unbound text field. the user eneters a score and I'd like the above validation to trap incorrect scores. But there's something I'm missing. I've tried setting the txtScore properties to general number... no luck there either.
Any ideas are appreciated.

I have two seperate, but related questions. I have been searching for awhile now for an answer, but so far no luck. Seems like it should be fairly simple, but I guess I'm just more simple
#1
I'm trying to establish a validation rule when entering data in a query. The tables involved are:
Locks (Serial#, Comb#)
Joint (Locker#, Serial#)
The query displays the Joint table fields, at which point I enter (or change the #'s from a previous year) the serial numbers for each locker.
How can I make sure that the serial number that is entered is a valid number based on the Serial# column from the Locks table?
There are nearly 1000 locks in the database, so using a combo box is not an option.
#2
After the locks are assigned to lockers, I then have to go and assign people to the lockers. This is also done in a query which takes all its fields from one table. In this case, I would like to have a rule that would not allow me to enter a repeat number that has already been entered above it...basically not allowing me to assign the same locker twice.
Thanks in advance for any help!
