General :: Triggering And Reading Multiple Barcode Readers
Nov 25, 2014
I will have a PC and a number of scanners in a production line. I will need at least 15-20 scanners and would like to plan for more if needed. When an operator clicks on a button I would like to have each of the scanners triggered and return the value. They can be done in turn or all at once (preferred for speed). I need to know which value came from each scanner. I would then compare the barcode read at each station versus what is supposed to be at that station and either pass or fail.

Hi Guys,
This might be pretty simple, but I haven't found anything on it (might not have looked hard enough!). What I am trying to do is scan a barcode label that I created in Access, when this is scanned, it goes to a table and opens the record that contains this ID and allows me to enter further data in this record. The further data will be data capture from a balance, which works fine if you select the location where the data is to go (using the mouse), what I need is for this location to be automatically accessed when I scan the barcode, hope that makes sense.
Also, is there any way in Access to either prevent data in a table from being changed once it is entered, or alternatively to mark the data as changed/edited from the original input?
Any help would be greatly appreciated.
Nigel

I want to be able to put a barcode in a field that when a reader scans the barcode it records the current time. Need it for access control to record who is in and out of the office. Reading other threads I understand it may be possible in Dlookup.

I am using a barcode font in order to generate a number as a barcode on my report records. In order for my barcode scanner to read the barcode it needs an asterisk at the beginning and at the end.
So, if my record ID is 62 - in order for the barcode to be displayed correctly, it needs to be on the report as *62* .
Without digressing into a discussion on barcode methods in Access, how can I precede and succeed each ID number field with an asterisks?

I am working on an MSACCESS database that reads data from SQL Server through ODBC Connection.
I have multiple tables that I have linked in and created Queries that read the data and created Make Table query.
However, I am asking if there's a way to bring the data through a query that doesn't need the linked tables. Is there a way to bring different fields from different tables into one query without needing to import all the tables, since the tables have many fields that I don't need.
For example in MS Excel, I am able to do that, a query that will bring external data from SQL Server from different tables and only brings the fields that I need for my report.

I see a lot of requests for this operation, but apparently .DB files are so general that sometimes it's impossible? Any all-encompassing program that can read files like this? I believe they come in different formats and are produced by a variety of different programs. The only thing I ever see though are files with [.db] as the extension.
If I open the one I have with notepad on a windows machine I see some of the info but some of it is not there and is garbled.

I'm scanning bar codes into the record search box, most of the time it works as it should but occasionally I get multiple "cannot open any more databases" errors. It still finds the product record but the error messages are super annoying. I am sure to clear the memory on the scanner each time before I scan in a new barcode but it doesn't seem to matter. Also sure to only have one or 2 forms open at a time, that doesn't seem to matter either. Most of the time I don't get the errors but when I have to click through like 10+ error messages (all identical). I only have one database open so I'm not sure what it even means. Also I have tried this in 2 different forms and it's the same for both forms. Seems like I get the errors in my initial scan and then after clearing them it seems to work without errors.

I am in need of consultation for MS Access reading data from ODBC connection. I have SQL Server that has all the data for the project financials etc.
I need a database that will read only certain data from the tables, for example, I don't need to import all 500,000 lines from SQL through ODBC connection, I just want to bring certain data for a list of projects whichever are opened and load only that data in MS Access so the group then can add additional details for that project in a shared MS Access.
Right now, all I can do is connect to that database through ODBC and brings all the data which I don't need all as it increases the size of the database, but just a criteria to specify which data to bring, if that's possible to do.

I am new to Access and this is likely a very elementary question. I recently created a database to track status of projects including progress and funding. The table contains several fields that record various aspects of funding. These fields are added (very simply) and create a calculated field that is a summation of those fields. The table currently contains approx 60 records. The calculated field functions for 2 or 3 records and will not calculate further. I have tried this in a form as well as a query. The form will change the same number, 2 or 3 records. When the query is run the result shows only the 2 or 3 records. What I am doing that is only reading and modifying those records?

I have two options on the main switchboard page and when I click on the second option it goes to a secondary page that gives me 3 options with the third option being to return to the main screen. When I select that option it does go back to the main screen but then on the main screen it shows the return to main screen option as well and when I select it.... it says " There was an error reading the switchboard items table." But I want the main screen to only show the original two options only.

I am working on setting up a Document Control System and have a table, called List_of_SOP where I have, amongst others, the following fields:
- Document Title
- Document Number (unique identifier)
- Responsible
- DL (where this is a multiline lookup column where one ticks the names of the people to whom this document needs to be distributed)
I want to be able to fill an array with the checked values of the DL field, given a particular Document Number. So far, the code is somewhat on these lines:
Dim rs1 As DAO.Recordset
Dim rs2 As DAO.Recordset
Dim rs3 As DAO.Recordset
Dim db As DAO.Database
Dim strSQL1 As String
Dim strSQL2 As String

I need to identify and parse (substring) a number of digits from a barcode. The barcode digit count will vary, based on the number of details included in the barcode.
For example: the barcode for GS1 DataBar begins with a 4 digit code of 8110 identifying the code as GS1. The 5th digit then identifies the number of digits directly following which constitute the manufacturers code, which can range anywhere from 6 digits to 12 digits. I need to pull the number of digits out of the barcode based on the value of the 5th digit placeholder and pull only that many digits from the string and replace them into another field. There are potentially 70 total digits in the barcode. I have only provided the first section, which I am asking the question on.
Simply put: I need to tell the substring to identify the number to parse from digit 5, (which will have a min of 6 digits and a max of 12)
How do I pull the information out of a string to create a substring in another field by first defining the number of digits to pull out (Digits 6 to 17 min of 6 digits and a max of 12 digits) based on a value within the string (digit 5= value)
So if Digit 5 is 6 the returned value would be: Digits: 6 7 8 9 10 11 (6 6 6 6 6 6 )
If Digit 6 is 9 the returned value would be: Digits: 6 7 8 9 10 11 12 13 14 (9 9 9 9 9 9 9 9 9)
The first portion of the barcode is below: There are other pieces necessary to be pulled the same way, but from other sections, and based on yet another X desinator field (the next with a min of 1 and max of 5) I assume the pull would be similarly completed.
I don't know how to write code, I have used formulas but not this detailed or specific.
Ex: I know = Min (barcode, 5, 6) would pull the 6 digits after the 5 spot, but how do I vary the 6 (count) number in the formula?
Example below: No additional spaces, dashes, letters etc. (A's = 1-4, X = 5, M's = 6-17)
A A A A X M M M M M M M M M M M M
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

I have a table full of meter readings. I want to have a field called consumption which looks at the reading just entered for that month and then subtracts the previous months reading for that meter which leaves the consumption.
Can I get a formula that can work this out automatically?

I am creating a inventory database for work. I am trying to get the cursor to jump to the next text box for data entry using a barcode scanner. I have a limit on how many characters there can be in this field but yet even after it is all filled the cursor stays in that same field. I am fairly new to access, especially in code building. Do I use "After Update" under "Event" in the "Property Sheet"?

Access front end, SQL Server backend.
----
I have a continuous subform (part of a tab control on a main form) whose name and sourceobject are both "sbfCannulae". There are about 10 fields on the subform, and all are bound to fields in a table. The primary key of this table must be generated by combining two other fields, which must happen just before the record is saved. (I know calculated data should not usually be saved in tables, but trust me. In this case it is necessary.)
Right now the user COULD enter data into the primary key-bound textbox, but since the user is me, I make sure not to do that.
When I enter data into all fields except the primary key, I get an error because the primary key cannot contains nulls...of course.
I use the following code to tell me when an event has been triggered.
Code associated with sbfCannulae:
Option Compare Database
Private Sub Form_Activate()
MsgBox "cann activate"
End Sub
Private Sub Form_BeforeInsert(Cancel As Integer)
MsgBox "cann before insert"
End Sub
Private Sub Form_BeforeUpdate(Cancel As Integer)
MsgBox "cann before update"
End Sub
Private Sub Form_Current()
MsgBox "cann current"
End Sub
Private Sub Form_Dirty(Cancel As Integer)
MsgBox "cann dirty"
End Sub
When I enter data into a new record, the Dirty event is triggered, but I cannot for the life of me figure out how to trigger any of the other events. No combination of values and nulls in any fields, clicking in other tabs, clicking to other records, or using the navigation buttons will ever trigger any events but Dirty.
The only msgbox I ever get is the one giving delivering the SQL error about the primary keys not taking null values.
What am I doing wrong?

Hello one and all
It may seem a rather simple question, though it continues to confound me -and I have searched to no avail :D
How do you trigger an event depending on what button is pressed on a msgbox?
For example, using a vbYesNo msgbox on a form, how can I assign events to either the Yes or the No option? Say, if "Yes" is clicked the focus would be set to a control on the form, and if "No" is clicked access would close down.
Any ideas?
I've currently got on the on click event of a command button (the bit in italics is fine, the bit in bold is not working!):-
Private Sub Command3_Click()
On Error GoTo Err_Command3_Click
Dim stDocName As String
MsgBox "Please select where you wish to save the exported file", vbOKOnly, "Save To Location"
stDocName = Month.Value
DoCmd.OutputTo acTable, stDocName, acFormatXLS
MsgBox "Do you want to select another History Extract?", vbYesNo, "Do you wish to continue?"
If intresponse = vbNo Then
DoCmd.Close
Else
Month.SetFocus
End If
Exit_Command3_Click:
Exit Sub
Err_Command3_Click:
MsgBox Err.Description
Resume Exit_Command3_Click
End Sub
But whether Yes or No is selected, the focus returns to the current form.
Cheers for any ideas

I have a form in my database that opens by default. I want to trigger a yes/no (yes would run a query, no would end) popup based on the value of a field in a table or query (i.e. if "now" is fifteen days past date in the table/query).
Any help would be most appreciated.

As above, I've noticed that it will only trigger if there are no textboxes on the form with a higher tab index than the control the keyascii is set for. Any ideas why, or what I'm doing wrong?
I've found this a lot and never bothered trying to find a solution till now. :p

I have a combo box in a form which simply pulls a text field from a single table - approximately 100 values to choose from. On the After Update Event, there is a basic "If null this, else that" VBA which just hides a subform if the value is null. This works fine, except there are a handful of values (I've found at least 6) that when chosen, trigger the NULL portion of the code! All the values are very similar, so I don't know what the problem is - for example, the value "D-11" works, but neither "D-10" nor "D-12" does.

we have gotten in to a routine of copying, pasting and bastardizing old databases instead of creating new ones from scratch - and we've had a problem recently where we've started off with one master database back in 2011, which has then been the base for practically every single major DB we've created ever since.So this month we've copied and pasted (again) and started adding new features to what's already there, and the thing has corrupted. I've copied and pasted the same version three times and added all the new bits, and the same thing has happened every time.
So this time I've copied and pasted and tried my best to clean up, get rid of the dead weight and (where necessary) create completely new objects, split into FE and BE versions etc, and I've reduced the overall weight of the DB by about 50%.Due to time constraints I now need to crack on and get this thing working again and, for the most part, it does - but now I'm having trouble carrying the filter over from the OnClick Event of a form button to the next form it's opening.
We're using the DB to record attendees at an Event we're running later in the year. This is the code that I'm running from the OnClick Event of the button on Form1:
Code:
Private Sub btnBkg_Click()
On Error GoTo Err_btnBkg_Click
Dim stDocName, vFilt As String
Dim vBkgRef As Long
Dim vContactID As Long
[code]....
You can see I've tried to use vFilt instead of the actual code for frmBooking's Where Condition, but for some reason it does not carry over to the form whichever way I try - when I open the immediate window and type ?vFilt it returns a blank entry. Not sure how to show the 'Where Condition' in the Immediate Window?Before Update, Open and Activate of frmBooking, but I'm hoping that the problem lies with what I've posted up here, as I don't want to get into posting the frmBooking code...
It may be worth noting that the button resides in the Header of a continuous form, with conditional formatting that changes the button caption depending on whether there is a value in the BkgRef text box of the record that has the focus.

Hi,
I am wondering whether it is possible to trigger the run of a macro when a form window is closed using the close button in the top right of a standard window?
If not, then is it possible to display a form in a window without the minimize, restore and close buttons?
I am currently using a setup whereby I have a button to close a form, and when clicked a macro is executed. However, the user could just as easily close the form using the close button of the window and the updates would not be performed.
Thanks in advance

I have a form which has been in use for some time now, and works extremely well for all users; as part of a recent update to that form, I added a few events to various controls; most of them are message box prompts to remind the user to do something, but one is automatic entry of text into a memo field when another field is updated, and it is really this last one that is causing an issue.
There is a command button on the form which has an embedded macro, created using the wizard - it is probably the last, or one of the last few buttons that have a macro as opposed to VBA.
Essentially, when this button is clicked, I would like a duplicate of the current record to be made (thus giving it an Autonumber ID of its own), and if possible I would like this to be done without triggering any of the after update events on the form. Is there a way to disable these events and copy a record in its entirety, re-enabling the events at the end?
