I have the following that I found in a post on Keypress of a text field to limit the field to only numbers. This works great only I need to disallow the entry of zero.
If KeyAscii <> 8 Then ' Not Backspace (important for error correction)
If KeyAscii < 48 Or KeyAscii > 57 Then 'Not a number
Beep 'Let the user know they hit an illegal key
KeyAscii = 0 'Don't let the keystroke through
End If
End If
I have one case about validation in the form
example: I have entry in table this mention below:
No.Register | Code_machine
________________________
001 | X01
002 | X01
001 | X02
003 | X02
003 | X01
002 | X03
How to make validation for this case when I will submit the data 001 and X01, the system will be cancel and show warning message : "Data Duplicate!".and of course with this happen, the user will be know what they will submit, it have been submit into table before by other user. if I will do make with one validation like noregister as checking data and use the DLookup, this is no problem.
I've tried to steal an SQL Postcode validator (This is for UK postcodes) and add it to an AfterUpdate event on a field in MS Access. It doesn't work, obviously,The VBA code is:
Private Sub Postal_Code_AfterUpdate()
Dim CHECK_Code As Integer
Dim LResponse As Integer
If InStr("[A-Z][0-9] [0-9][A-Z][A-Z]", Postal_Code) = 0 Then
CHECK_Code = 0
[code]....
Also, how would I put the Check_Code value into the Message box to see what it's bringing back?

I have 2 combo boxes on a form. The 2nd box is not visible unless the 1st box is set to a specific value (Illness). Once the specific value is set, the 2nd box appears with appropriate data for selection.
Goal #1:
I would like to have the form checked before it is closed to ensure that if the condition in box 1 is "Illness" then the 2nd box must have a value and can not be null.
Goal #2:
I am also having problems with the 2nd combo being visible when form opens or becomes current. The field is set to visible=false normally but needs to be visible when form opens if the conditions mentioned above are meet (true).

I have a button on a form that when I press it, I want it to validate a user's Windows Login ID in a text box on the current form against a table before allowing them access to a form.
If the Login ID in the text box does not match any value in the table I have defined, I wanted a MsgBox displayed saying invalid credentials. Of course if the ID exists in the table, I'd like it to open the next form.

Basically, a function that chooses what Status Validation to run then knows when to stop that displays some very simple predictive Inference.
Each Record has a Status. The Status will generally be correct 85% of the time. Once in a while, various things in the database are updated that triggers the business need to change the status.
-A collection of Rule based validation functions matches each Status.
-The objective is not to run Rule 1 through 40 sequentially for each record.
-Each Rule Validation function is lengthy and can take 0.1 seconds per rule (per record).
-If the current record's rule is still valid 85% of the time, Then run that Status Rule Validation function first.
-If the Validation returns True, there is no need to run the rest of the rules. Move to the next record.
The challenge: Statistically, if the Current Status failes its Rule Validation, there is a high probability that one of the Status Validation Function near to the current Status will validate to true.
Like the board game Clue, once a Validation Rule comes out False, there is no need to check it for that single record again.
In an extremely simplistic world, think about Status of : Order in Progress, Order Completed, Completed Order Paid, Shipping in Progress, Item Shipped Ready, Shipped, In Transit, Delivered, Rejected, Payment Recended, ...
So, if the current status was In Transit, there is a higher odd that Delivered would be the next. There would be no need to start from the beginning again. The wonderful world of Metadata.
I am using following routine to lift data from Excel files into Access tables. Whole thing works, well, most of the time. The only issue I have is the spreadsheets are received from warehouses and even though they have been given strict instruction to stick to the template, I have had to adjust the spreadsheets. Amongst errors I get are:
Field 'F16' does not exist in table 'SA1'. (In this case I simply delete the last most empty column to fix this).
Or there are column name spellings and in such cases, I get no error and the simply code hangs.
Is there any routine that I could incorporate in the code that clearly states what issues are being experienced. This way I can pass the db to the user to run it themselves.
'Dim dbs As Database, tdf As TableDef
Set dbs = CurrentDb
On Error GoTo Macro1_Err
DoCmd.SetWarnings False

I am trying to add extra validation in a sample db (done in A97 (converted to A2003)see attached.
I am attempting the following: Please not that the db has existing validation which I would like to keep (or change if advised) ...
Conditions:
1. Input into field "ID" must start with the letter P or p or R or r
2. If field "ID" starts with the letter P or p and field "Code" starts with the letter R or r, then a message stating that this combination is invalid should appear
3. If field "ID" starts with the letter R or r and field "Code" starts with the letter P or p, then a message stating that this combination is invalid should appear.
If a new record is created, insert date only if customerID is not null

There are 4 unbound dropdown list box that will have a default value of empty string. All 4 must have values entered (data is required).Once all 4 are required - the bottom 5 text box will become enabled (optional data).Forcing the user to click on a Validation Button
Some users type then use the mouse to select the next.Other users type to select then tab.The trick is: After filling in the 4th listbox and validating all 4 have values, the event must trigger code to enable the 5 optional text boxes below.This provides a seamless data entry environment.
I have been doing this in other places, but the transisition after the last required field is complete gets ugly.If Trim(cmbBoxname1 & "") = vbNullString ' check all 4..If it is the 4th one, the event seems not to happen quick enough for the bottom 5 text boxes to be enabled so the user can continue with data entry.
how can i validate a field so that the data entered must be between the values of 1 and 10?
thanks in advance

Hello!
Can someone tell me how to do a validation. The one I am trying to do is check Track No is not duplicated.

Can someone help me please!
Thanks
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

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?
