Validation: Cdv Code

Jan 20, 2007

Hy everybody!

I need to validate a 9 char long number. The input mask is 000-000-000.
The last character should be the = (1stchar*3+2ndch*7+3rdch*3+4th*7+5th*3+6th*7+7th*3 +8th*7) Mod 10.
So for example: 123-456-788.

Can somebody help me?
Thanks a lot, gerland

Post Code Validation

Apr 7, 2006

I have searched the forum for posts on the subject of UK postal code validation and found the reg expression that seems to be recommended for this.

I tried the expression but it will not accept this postal code? TS183AM

Like "(?:(?:A[BL]|B[ABDHLNRST]?|" & "C[ABFHMORTVW]|D[ADEGHLNTY]|E[CHNX]?|F[KY]|G[LUY]?|" & "H[ADGPRSUX]|I[GMPV]|JE|K[ATWY]|L[ADELNSU]?|M[EKL]?|" & "N[EGNPRW]?|O[LX]|P[AEHLOR]|R[GHM]|S[AEGKLMNOPRSTWY]?|" & "T[ADFNQRSW]|UB|W[ACDFNRSV]?|YO|ZE)" & "d(?:d|[A-Z])? d[A-Z]{2})"

Please Review This Code, (simple Code) New With Codes

Feb 16, 2006

Works great, but when I hit the number "3", (3 times in row) it will let me into the form. I want it to not let me in IF I don't know the password.

Where did I go wrong?

Private Sub Form_Load()
Dim pw As Variant

If InputBox("What is the password?", "Password") = "1" Then
Else
MsgBox "Invalid Password", vbCritical, "Sorry Charlie"
DoCmd.Close
If InputBox("What is the password?", "Password") = "2" Then
Else
MsgBox "Invalid Password", vbCritical, "Sorry Charlie"
DoCmd.Close
End If
End If


End Sub

Using Code To Unprotect And Protect Viewing Code

Jan 14, 2007

I protect my code from people being able to read it by setting a password on the code from Tools > Properties, selecting the Protection tab and entering a password, and clicking "Lock Project"

Is there a way to write code that will remove that Lock Project check and check it back on?

I've looked through the Application.SetOption command and it doesn't seem to be one of the choices. It would be very helpful if someone knew how to do this.

Thanks

Validation Or VB

Feb 7, 2005

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

Mar 30, 2005

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 :)

Validation Help

Jan 21, 2006

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?

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

Validation

May 15, 2005

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.
