Tables :: How To Check That Linked Table Exists

Apr 16, 2013

Background: In my Access FE, I have created a "linked table" to a file on our AS400 database. I know I can check the MSysObjects table for the linked table name, but sometimes the file actually does not exist on the AS400.

The file can be in one of three states.File exists with data.

File exists, but is empty.

File doesn't exist.

Question: What is the best way to determine the status of this linked table (file)?

Check If Value In Table Already Exists

Nov 20, 2006

Hi

I have a problem where a user would enter a project code eg 113-099. I put in a list box that filters all the project codes for instance if the user enters 1 it will show all codes starting with a 1 and every additional number they enter it filters the list box to show which codes already exists! I hope this makes sense.

The problem i have is i need to check when they enter the project code that it is a unique value. The Database developer we got in didnt index this field as no duplicates allowed and as result we have large amount of duplicate project codes.

I have started to experiment with Dlookup but with no great success.

If anyone can help it would be much appreciated as i dont have much experience with access.

The field name on the form is

[forms]![projects_frm].[project_job_number] and the table which stores this information is [projects]

How To Check If Table Already Exists

Aug 12, 2012

Is there any way to check if a particular table already exist in MS Access Database using ACCESS VBA?

Actually I'm creating temp table on the file but I want to check if temp table already exits then need to delete before creating.

e.g. I can check if query defniniton already exists using below code:

Code:
If .DCount("[Name]", "MSysObjects", "Left([Name],1) <> '~' AND [Type] = 5 AND [Name] = '" & strTempQueryName & "' ") <> 0 Then
.DoCmd.DeleteObject acQuery, strTempQueryName
.CurrentDb.QueryDefs.Refresh
End If

Check If Record Exists In Table

Feb 6, 2013

I am trying to check if a record exists in a table.

Dim cert As String
Dim existingRec As Variant
existingRec = DLookup("[Certificate]", "[Fire]", "'cert' = 'cert'")
If existingRec = Null Then

Else
MsgBox "The Certificate " & existingRec & " is in the database"
End If

Note - Certificate is a column in the table "Fire"

Problem is that existingRec only finds the first value in the Certificate column, How do I get to check the entire Certificate column?

How To Check A Computer Client Allready Off ?

Jan 18, 2007

Right now i using client server application using
- Frond End : Ms.Access + Winsock with UDP protocol. ( This program like Yahoo Messenger )
- Back End : Sql Server

I made this program for Remote Trading.

every second server or client will be send data.
Sometime Server send data only to specific client, so when client logon to application, I save the IP number and after logout i clear the IP

the problem will be happen when the computer client Hang, server cannt send a data to that computer, and waiting for ever until server hang too after that all client will be hang.

and the question is How to check status computer already ON or Off
i mean before server send data, server will be check status computer with that IP, If status computer On then True else False, so if computer client off, server don't need to send data.

thx

Reports :: Check If Client Has Email Address

Jan 2, 2014

I currently have details of my clients in a table called tblSites, this tble includes a field with an email address. I currently produce a invoice which is automatically saved as a pdf and an email generated with the invoice attached. However, a few clients do not have email addresses (these are sent by post). My code (see below) will successfully produce the email with the attachment, but if the client does NOT have an email address in the tblSites it comes up with the "Invalid use of Null" error. What I want it to do is continue the process of just saving the invoice with a Msgbox stating "This Client does not have an email address etc etc.

'Save Invoice as PDF and annotate Invoice Number, Date and site name

Dim StrFile As String
Dim slSQLString As String
Dim rsEmailAddress As Recordset
Dim slEmailAddress As String
StrFile = "C:Redwatch Invoices" & Forms!frminvoice!txtInvoiceNr.Value _
& "-" & Format(Date, "dd-mmm-yy") & "-" & Forms!frminvoice!cboSiteName & ".pdf"

Check Query To See If Record Exists

Dec 4, 2006

Hello all,
I have a form that looks at my "master table" where users put in general info about a sheet of material.
There are two combo boxes on this form, Batch# and Lot#. They will use the same Batch# and Lot# for many sheets. Every time a new batch and lot are entered, this will bring up a pop-up form where the user needs to take a measurement of that batch and lot for QA. This will go into a different table, where the batch and lot #'s are unique(many of the same batch#'s with different Lot#'s).
After the lot# is entered, I want to run a query in VB that looks for those unique identifiers, and if it doesn't find a record, my pop-up form will run.
This is probably something very easy....... It was a very long weekend and I'm tired of thinking.

Thanks
Scott

Check If (Exact) Record Already Exists

Feb 29, 2008

Hey all,

Tables

ProductsProductBrandSize
PurchaseDetailProductPriceQuantity
Forms

frmFoodSub
Combo BoxesiProductiBrand
TextboxsiSizeiQuantityiPrice

For a couple of days now I've been trying to devise a way to achieve what I want, but I just keep going in circles and hitting errors (thanks to forum members, I've been able to solve most of them.) So, here's what I want to be able to do:

Input a product using the iproduct combo box (which gets its list of values from the Products table); its brand, using the ibrand combo box; and its size using the isize textbox, all in the frmFoodSub form. I then want it to check to see if an exact record already exists (ie. the same product, same brand, same size.)

If it doesn't exist, I want to create it. If it does, I want to do nothing. Then I want the product - either the one I just created, or from a record that already exists matching the iProduct input - to be input into the product field of the PurchaseDetails table. I then want to use iQuantity and iPrice textboxs, already linked to the PurchaseDetails table, to input the newly added product's quantity and price.

I hope my explanation was clear enough. I'd appreciate any help with this you may be able to offer.

Modules & VBA :: Check If Value In A Record Exists And If So Indicate Which One?

Jan 2, 2014

I have created a form which enbles users to enter data into the fields which will add a new record to my table. What I am trying to do now is to create some kind of validation rule that will check whether the record already exists.

I need it to work this way; there are four input fields- 3 text and 1 is a date filed. When the user enters a new record they are not allowed to create a record that conatins the same combination of values. So if one record has for example filed 1 = 1 field 2 = abc field 3 = def; then no other record can have the same combination of values.

If the user enters an already existing combination there would be an error message saying which field is incorrect. If the combination doesn't exist it would add the record and display a message that the record was successfully added.

How can I do this?

General :: Check If File Exists?

Nov 27, 2013

I have a table with several thousand records. Each record as a path field that indicates a specific file that is associated with a given record (not just a directory, it identifies a specific file). I'm pretty sure that most of them are correct but I've seen and been cleaning up paths that have had typos in them or were otherwise not setup correctly. Is there a way that I can generate a report or a list of some sort that would tell me exactly which file paths exist and which ones don't? or even just the ones that don't.

Modules & VBA :: Check To See If SQL Server Exists

Nov 24, 2014

I have an application that I have automatically checking to see if tables are valid and connected, etc. If the app finds that the tables aren't connected or aren't working, it automatically tries to re-connect those tables in the background without the user's knowledge. The time I'm having trouble is if the SQL Server doesn't exists (the back-end tables are on a SQL Server). I would like to check to see if the SQL Server exists before I try to re-connect tables so that no SQL Errors pop up but I'm not sure how to figure that out with VBA.

Modules & VBA :: Check To See If A Record Exists First?

Sep 10, 2014

I have a form, which has a combo box which a user can select an employee - the combo has three columns (Employee_Number, Surname, Initials) although the Employee_Number column is set at a 0 width, so not visible.

The form is bound to a query which only shows records that are 'Active'

When a user selects and employee in the combo box, I want the AfterUpdate event to check and see if there is already an active record - if there is, throw up an error message and then reveal a couple of buttons giving choices what to do next; if there isn't an active record, reveal three textboxes and then populate those textboxes with the values from the three columns from the combo.

The bit that is sticking me is the search - - I have tried DCount, but can't seem to get it to work

Here is the section of code that I am battling with:

Code:
Dim EmpNo As String
EmpNo = cboEmp_Check.column(0)
If DCount("Employee_Number", "Incomplete_Training", "Employee_Number=" & EmpNo) > 0 Then
MsgBox "Existing", vbOKOnly

On Lost Focus....check To See If Primary Key Exists

Jul 20, 2005

Hi there

I recently have been given a database to get into shape.

One of the main problems is that when a person enters data into a form, They until the leave the form are not aware if the primary key has been used before.


Let me try explain.

I have a booking number (which I have only in the last couple of days made a primary key and also changed it so there can be no duplicates)

I have changed the form around alittle so that the person entering the new data must start with entering the booking number.

How can I make a piece of code that once the booking number textbox loses its focus the code then checks the table to see if that booking number exists. I would like for the person to establish that they need to enter a new booking number before getting to the end before seeing that the booking number already exists.

I hope I am making some sense.


TIA

Check If File Exists And Replacing Files

Oct 27, 2005

hey guys

i'm trying to do something that i thought would be pretty simple. what happens is i have 2 files that get used, one by access and one by excel. they are both the same, except if one gets modified then the other doesnt obviously. (theres reasons for having the 2 files).

anyway. in access i want it to pick the newer of the two files (i assume this is using a fso system object?), if the one it normally doesnt use is newer, it should copy the new one over the old one and continue using the one it normally uses.

i cant simply use the other file as another user always has that file open.

any sample code on how to check if things are modifyed at a later date? and copy/pasting using those fso objects?

cheers guys

Modules & VBA :: Check To See If Email Address Exists

Jul 14, 2014

I can already send emails out as PDF files when an email address exists, however, I'm trying to validate whether or not an email address does actually exist. My problem is, there are four possible locations where an email address could be: MainEmail or Contact1Email or Contact2Email or Email (the last one - Email - is in a separate table).

Four text boxes exist on the form that is being actioned (the form is based on a query to extract the relevant information) and are available to test for an email address being present. What I'm struggling with is ensuring that the 'To' box in Outlook always gets populated or Outlook chucks a hissy fit. I have been trying various IF Then Else and Do Loop plus a myriad of other ways but none are reliable, especially if no email address is present which can be the case.

I have a database that involves a lot of data about ppl and I'd like to prevent duplicate entries.

I have a form that gathers data. I'd like to have a button after name, surname and birthday are written.

A click on the button would display a msgbox that says that person already exist, maybe even with the added - edit the old entry/add new record anyway/abort options.
