Getting A Possible Duplicate Warning?
Feb 3, 2004
I am running Access 2002 on Windows XP Pro and have been teaching myself this program. I have created a large contact database with one main table and associated forms for entering data as well as reports driven by queries. What I can't figure out is how can I get a warning message to appear if a user enters a possible duplicate individual into a form. For example, if someone is entering an individual into a form that is bound to the main table and the same last name belongs to an individual already in the table, it may or may not be a duplicate. I'd like to learn some way of immediately checking the potential duplicates and then deciding weather or not to continue with the entry. Thanks much, in advance for any suggestions.

Help!
I have 2 tables with the following fields:
Table1
CustID - (Autonumber/PK)
FirstName
MiddleName
LastName
Address
City
ContactNumber
Table2
CustID
VehID - (Autonumber/PK)
PlateNumber
FrameNumber
ProdNumber.... etc.
Property of all fields in Table2 are set to Indexed(No Duplicates).
I need a warning message form to appear on the screen if User adds a new record of PlateNumber which already exist. Then, automatically shows User who currently owns that PlateNumber.
Thanks!

I have struggled with this for so long now I hope someone can help.
I have a form called frm_Collections which is run from the query (qry_Collections). When I type into the Reg field in the Form I would
like the user to know if the Reg details have already been used in a
previous record. The database can have duplicates in this field, however a
"Warning Message" would promt some investigation.
I have tried loads of DLookup on Before Update, but really need setting of
in the right direction.
Thanks

I have a data entry form linked to a table that records daily catch details (date, invoice number, buyer, kilos, price, etc). For the last 2 years I've been using the no duplicate index on the date field of the table to prevent duplicates, until he (my husband) decided that he wanted to sell his catch to different buyers on the same date.
I've changed the index to allow duplicates but now I need to create a message box which warns that he is entering a duplicate date as he has a history of trying to enter the same info twice. I've found examples of code that warns on duplicate text entries but nothing for duplicate dates?

We are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT
COLUMN in UPDATED HEADCOUNT - EMPID
FORM CELL user will input an EMPID - newEMPID
FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")

i recently installed MS Office 2003, and now everytime i am opening an access database, i am getting a security warning asking me if i would like to block unsafe expressions. From the help i read that in order to get rid of this security warning, i should install the Microsoft Jet 4.0 (SP8). After i download it from the Microsoft Website, when i am trying to install the exe file, i am getting a message, that my system already has a newer service pack installed and i do not need to install it. However, since i do still get this message about safe expressions, is there any other alternatives how can i get rid of it ?
Thank You

I need to be able to cause a warning box to appear when records for high risk clients are viewed. When a risk assessment is carried out I need to show the result as being either High, Medium or Low on the Client Form. If the result is high I want every worker accessing the record to be in no doubt as to what they need to do if a visit to the individual is being made. Thanks in advance.

Well, problem I should know how to solve! Or at least be able to find in the "search" But...... niether..... So this should be a simple one...
Have a form with a ClientID combo.... If this record is changed I want a warning message before... So I decided to do it as a function then call it on change...
Private Function ChangeClient()
Dim Msg, Style, Title, Response, MyString
Dim Cancel As Integer
Msg = "You are about to change the Client for this Project!" & Chr(13) & "Do you want to continue ?"
Style = vbYesNo + vbCritical + vbDefaultButton2
Title = "WARNING"
Response = MsgBox(Msg, Style, Title)
If Response = vbYes Then
MyString = "Yes"
ElseIf Response = vbNo Then
MyString = "No"
Cancel = True
Undo
End If
End Function
Now the problem is.... What event to call this on!?!?
It works fine on several events on a current record...
BUT... when it is a new record, and you pick the client from the dropdown, it sees a change and runs the function. That clear?
I was thinking of running a "If ... Then" statement so if it a new record the function will not be called.
Got to be an easier way to simply warn of a field change!
Ideas???
Thanks

This should be a simple one.... But can't seem to find the answer.... I have put a line of code on the open event of a seconadry form.... First form is "Clients" second form is "Contracts" If no the client has no contracts the code goes.....
Private Sub Form_Open(Cancel As Integer)
If IsNull(DateOfSale) Or DateOfSale = " " Then
MsgBox "No Contract Exist"
Cancel = True
End If
End Sub
After the first message box I get a "Access" message box... "The OpenForm action was canceled" ....... Thats fine.... we know that... But we don't need to know that. How can I stop the second message box from opening? Or can I ?

Hi,
I was wondering if anyone might be able to help me out. Is there a way of programming the access database in such a way that it doen't shut the whole database if someone by accident, presses the cross sign which is right on the top right hand corner. I'd like it to ask the user if they really want to quit first. This way, all the unsaved work can be saved prior to the closing.
Is this possible?
Thank you in advance

I designed a combox and also set the property of 'limited to list' to yes. I also declared the function NotInList with my own message box. But, the MS-Access default warning message box still comes up after displaying my one.
If I turned the property of 'limited to list' to no, it can trigger the function at all.
Does anyone here have any idea on how to turn the system default warning message box off?
Many thanks

Hey all,
Thanks for all of the help you have already given me.
Here's another.
What I'm trying to do it get a field, which is a combo box, to pop up a warning when someone tries to change it. I'm trying to keep people from unknowingly change the name field of the time sheet. I only want the warning to show if the field being changed already has a name in it.
Here is what Ive tried.
Private Sub Employee_BeforeUpdate(Cancel As Integer)
If Not IsNull(Me.Employee) Then
MsgBox "Are You Sure?"
End If
End Sub
The warning works, but it shows up regardless of the field being empty or filled.
I'd like to have it so I get a msgbox using vbyesno to give the user a choice whether to keep the change or accept it.
Any help would be greatly appreciated.
Thanks again!

I have read through the various posting regarding ACCESS 2003 security warnings. As like everyone else, I receive a security warning stating, “This file may not be safe if it contains code that was intended to harm your computer.” I have already installed Microsoft Jet 4.0 Service Pack 8 and I have already enabled sandbox mode. This warning still appears when I try to open databases sent to me by other people. It also appears when I try to create a new database from my own computer. I understand why this message may appear when I open other peoples’ databases, but why would this error message appear on my own computer after I create a database from the very same computer? I would like to market my databases to specific clients, but I need to eliminate the security warnings that would appear each time they opened my databases from their computers. I don’t want to suggest that people change their security levels to low in order to open my database. For this reason, I am considering the option of digitally signing my databases with an authenticated signature. As something like this would run anywhere up to about $400.00, I want to make sure that it would be the best, and correct, option for me. My ultimate question: If I am already trying to create databases from my own computer and receive this warning message, would a digital certificate work in eliminating the error message for my future clients? Also, I understand that I may use the signatures for up to a year. Would I be able to use this for multiple databases that I create as long as it’s within that one year, or would I only be able to sign one specific database and use that same database for the entire year? This is a bit of a pricey endeavor for me, so if there are any other options, I’d love to hear those, too. Thank for the help in advance!

Hi,
i was wondering if anyone might be able to help me out here. I've been spending hours but to no avail. It seems to be a very trivial problem but i'm just out of luck.
I've been getting this pop-up message everytime i try to open up an access application such as .mdb files.
Open file - Security Warning
Do you want to open this file
...
two buttons: Open & Cancel
My question is if there is a way to turn it off or disable this warning from popping up when opening an access application.
Thank you in advance

We have shared MDE, when second user opens gets message: [B]You do not have exclusive access to the database at this time. If you proceed to make changes, you may not be able to save them later.
The message seems to repeat for each compiled object (Form, Report and Module).
Helptext states occurs when in design mode - but not in design mode!
Any ideas as to how we can suppress the warning?

Okay,
I'm not sure if this is the right discussion to ask this, but it seems the closest to my question, so I apologize if i'm mis-posting.
I'm doing a "run-time" insert into a table, from the VB Script. A button pops up an InputBox, and the returned string is added into the table, via a SQL command. However, upon execution of the SQL command:
st=InputBox("New Entry")
call DoCmd.RunSql("insert into table1 (field1) values ('" & st & "');")
I get a warning dialog pop-up from access, informing me that it's about to append 1 row(s) into the table. Is there anyway to deactivate that dialog warning box so it doesn't pop up every time i use an insert into statement?
Thanks

Hi there,
I like having the action query warning appear with what I am doing - "You are about to update xxx rows". The problem that I am having is that when my RunSQL statement in the code executes and selects no to the warning, I get the error -
Run-time Error '2501'
The RunSQL action was canceled.
How can I trap the no selection so that this vba error does not appear?

Private Sub Command40_Click()
On Error GoTo Err_Command40_Click
DoCmd.SetWarnings False 'Turn Warnings Off

Exit_Command40_Click:
Exit Sub
Err_Command40_Click:

End Sub
In essence its just a save record button which has a macro attached to it to run on mouse down. This macro runs a query to update a table which then updates the form upon saving. The warning messages to say it is deleting the old table and updating with new values keeps popping up even though im using the above code. Any idea on how to supress these warning dialogues when i click save?

I would like to know how to display a msg box for missing or duplicate information when entering data into a form. My database keeps track of call accounting codes and the code is the primary key index field. I use macro's for all of my automated tasks such as finding codes, filtering for available codes and such. What I want to do is to display a simple message when adding a new one to the database if they forgot to enter the code and if they did enter a code if they entered a duplicate. The default error meesage tells them there is a problem but they won't know how to fix it. I know I should use the Before Update and After Update but I am not good at writing the vb code. I found some code in one of the the threads and copied it and changed the field names but it failed. I need a simple message like "You did not enter the Fac code" and "The Fac code you entered is already in the database please check your information."
The field name of my primary key is "Fac"
Thanks in advance for anyone that could help me with this.
