Modules & VBA :: Multi User Environment / Find First Method And Update
Aug 21, 2014
I have a problem in multi user enviroment, with finding and locking a record in database.When one user finds, blocks and edit record ... another user in the same time can find the same record and overwrite it (User and Status values). It is just like he didn't see the changes making by another user.Each user have a copy of the front-end, back-end is on the shared disk.Here is the code to find new record:
Code:
...
Set rs = db.OpenRecordset("tblTable1", dbOpenDynaset)
rs.FindFirst "[Status]='New' And [User] Is Null"
ws.BeginTrans
rs.LockEdits = True
rs.Edit
rs![User] = username
rs![Status] = "Assigned"
rs.Update
ws.CommitTrans
rs.Close

Hi,
I need to allow my MDB to have 15 users accessing at the same time. They will be updating different parts of the same table using different forms. The system will also do an automatic update from another system in 15 mins interval.
Is it possible? If so, how do I configure my access database?
Please help.
Thanks!!!

I'm in the process of rolling out a new database that will require some data entry from approximately 35 users.
I have been told that database corruption WILL (not might) occur if more than one user is in the database at a time, which I find hard to believe. I was told that if multiple users who have different permissions levels are in the DB at the same time, this will cause corruption.
Has anyone heard anything like this?
Also, there will only be one or two forms that my users will be using for data entry. The rest is report running. If I set the value Record Locks on the form to EDITED RECORD, will this prevent corruption?
Any input you could provide is very much appreciated. I haven't been able to find any info specific to this issue.

I have multiple users entering data on bound forms. I have three required fields, all in the first 3 fields of the form. My question is, can I program something to where Access will update the record, after the 3rd required field, so that other users are not having to wait to enter there new record?

I have a Access data base (2007) which i splitted and store the back end database in a file server where all users have full control and the individual copies of front end put in the users computers. Unfortunately when one user is using the programme, others can not use. Following error msg appears. Both back end and front end are running under shared mode ( not exclusive ).
"Could not use xxxxxx_Be.accdb; file already in use."

I am developing a small database for use in a multi-user environment: I have split the tables off and am testing with two copies of the front-end on different machines. All seems to work well except on one form.
On this form, the value of a bound control (exposed as a number of radio buttons) is used to make related controls on the form visible or invisible. I use the AfterUpdate event to trigger appropriate VBA code to accomplish this; it works well.
However if two users have the same form open at the same record (unlikely, but not impossible), and User A changes the value of the control via the radio buttons, Access will eventually propagate the change to User B's copy of the form but the AfterUpdate event will not be triggered and the form becomes inconsistent. I understand that events are only triggered when a user makes a change to a control; how can I be alerted when Access makes a change?

I currently have the following setup for my database which is working as desired when only being used by one user at a time:
Front end: Access 2010 database in Citrix
Back end: SharePoint List
The problem is that only one user can open the Access Database at a time since this action locks the database for other potential users. The locking occurs due to this link to the back end SharePoint list.
allow multiple users to update the SharePoint list through the access database at the same time?

I have a multi slect list box (simple) and I need to find and select an item using vba - e.g., the bound column is the ID field and I need to select a specific ID (which will be different each time) as opposed to selecting the 100th record for example. How do I do this?

I copied Students application in Access 2007 and modified it to fit needs of a school for students with disabilities. I know absolutely nothing about macros, so where needed I substituted VBA. It is now a mix of macros and VBA. But now I cannot post values from a combo drop-down list on the second tab. I get a "boink" sound when I try to post the selection. I have adjusted the properties of each combo field to match where it was successful before and tried again. No results.
The fields are located on the second tab which lists contacts for the student. The proper values show up in the drop-down list. It is just that the value chosen will not populate the field.
I have used combo boxes extensively before, but never in a macro environment.

Hi guys,
I've seen different log in forms and tips on multi-user use but can't seem to find info on the following...
We have 6 people at work and I'd like to assign which user updated a form or created a new record...this would be particularly useful on the sales part of the database to track who made a call to a particular customer...
Best ideas anyone?

I have a multi user database in Access 2000 that is on a server. The individual users have shortcuts pointing towards the server instance. One user and one user only when opening the shortcut gets the error "you do not have exclusive rights to the database" .
All other users can enter the database with no error box. I have checked the advanced setting under options and they are correct. Ironically if you go to start and open access then navigate to the database shortcut. It opens with no error.

My update statement is shown below. What this is to do is change the PGTIN record in PP TBL to the GTIN that is in the UPC TBL where the UPC Code on the form is the same as the UPC Code in the UPC TBL. I am getting the error message "can't find field..." I have double and triple checked the field names but cannot find my error. Both PGTIN and UPC Code are text fields.
strSQL = "UPDATE [PP TBL] SET [PGTIN] = '" & [UPC TBL].[GTIN] & "' WHERE ([UPC TBL].[UPC Code] = '" & Me.UPC & "');"

How can I have a user enter the WHERE criteria in the Set Rs statement below.
Set Rs = CurrentDb.OpenRecordset("SELECT [Net] FROM [tblRecap] WHERE [Yr] = 2000 and [Event] = 'lancaster'")
I would like a message box to ask the user to define the [Yr] = and [Event] = fields since they would change from time to time and then pass the values to the OpenRecordset method. Is this possible? Can someone help supply the code?
A parameter query won’t work because when you manipulate these queries in DAO through VBA you need to supply the parameter value before you open the recordset object. If you don’t DAO generates an error.
Here is my code:
Option Compare Database
Option Explicit
Private Sub ReportFooter_Format(Cancel As Integer, FormatCount As Integer)
Dim ConsqWin As Long
Dim ConsqLoss As Long
Dim tmpWin As Long
Dim tmpLoss As Long
Dim Rs As DAO.Recordset
Set Rs = CurrentDb.OpenRecordset("SELECT [Net] FROM [tblRecap] WHERE [Yr = 2000 and [Event] = 'lancaster'")
Do While Not Rs.EOF
Do While Rs!Net > 1
tmpWin = tmpWin + 1
Rs.MoveNext
If Rs.EOF Then Exit Do
Loop
If Rs.EOF Then Exit Do
If tmpWin > ConsqWin Then ConsqWin = tmpWin
tmpWin = 0
Rs.MoveNext
Loop
Set Rs = Nothing
End Sub
By the way the YR field is a number and not a date so the WHERE clause doesn’t need #2000#
Any help would be appreciated.

I have a form in my front end database that is supposed to allow a user to search for a record based on account number and then make changes to the that record and for it to save in the back end database. I have the search function working where it populates different input boxes on the form with what is stored in the back end database but I cannot get the update function to work. I have tried to assign each input box with a variable and then run an Update SQL function to update each of the fields but the updates are not storing. Any example of a successful update statement that uses VBA variables in it or a way to update a specific record via a recordset type function?

I'm attempting to build an import module so that my users can take data from different walks of life and import it into my tables. I'm doing this by setting up a module and allowing the user to specify which column data will come from when importing data. So lets say I have a field that is CustomerID in my table and user one pulls data from 1 place and in his excel or csv file, customerid is in field 1. Another user does the same thing and its in field 2.
How can i make some form of a loop that when I'm attempting to update data, i pull the correct column?
strSQL = "SELECT * FROM tblImportTable"
Set rst = db.OpenRecordset(strSQL, dbOpenDynaset, dbSeeChanges)
With rst
Do While .EOF = False
If IsNull(DLookup("DefaultValue", "dbo_tblImportTemplateDetails", "Template_ID=" & Forms!frmImport!TemplateName & " AND FieldName='CustomerID'")) Then
[code]....

I am new to VBA and I'm trying to write a query that will update a table with dates based on user input. For example a user will run data each Monday and that date will be day01. The date table has 28 days total and I need each day row to update with the next date i.e. day01 is 12/30, day02 is 12/31, day03 is 1/01 etc..I am having issues just running the update the query. I get a too few parameters error message on the strsql statement. There are only two columns in the table, order_day(date column) and date_value(text). I want to update order_day. I also need creating a loop so it knows to go back and add days to the other values.
Here is what I have:
Code:
Sub Update_Dates()
Dim rs As Recordset
Dim db As Database
Dim lmsg As String
Dim transactiondate As Date
Dim strsql As String
[Code] ....

I am new to access 2010. I have a table called "Forecasts", and I wish to update the timestamp with todays date, whenever the user makes a change to the qty of goods forecasted.
I have been researching online for the solution to the correct format to datetime, but it doesnt seem to work.
Code:
Dim todayDate As Date
todayDate = Date
Dim sqlString As String
sqlString = "UPDATE [Forecasts] " & _
[Code] .....
The messagebox shows:
UPDATE [Forecast] SET Branch_Plant=123, Item_Number_Short='222', Description='AAA', UOM='EA', Estimated_Cost=123, Requesting_Business_Unit='AAA', End_Customer='CCC', Project ='Secret', Timestamp=#26/12/2013# WHERE ID =24
Then I hit a syntax error. Whats wrong with sqlString?

I have read a lot about if multiple users want to share an MDB, they have to create BE and FE and split the database.
I understand having to do that if all those users want to write to the MDB simultaneously.
I have a situation where one person will do data entry (write access), and two other users will just want to view and perhaps just search the database (read).
If only one person is writing at any time, do I have to do all that splitting and FE/BE configuration?

I plan to create a multi-user application on access 2000. There would be more than 20 users simultaneously logging in the database. The database would be kept in Server with high config. The users would work on the database (server) from their workstations. Forms/Queries/Reports ... are in the workstation (client). The database may growup to 70 MB every 3 months. The application will run on the database for 3 months which will be replaced with a new one after that period. Is it a good plan to do so on Access 2000. Am worried about the network traffic. Will the users face it as a very slow application ???
(SysConfig workstation: Win2K Pro/ 128 MB RAM/ 40GB HDD/Pentium-4)
Any suggestion is appreciated. Thanx in advance.

Hi
If I want several users to access a database from their network pc's, should I place the access database .mdb file on the server and set the Sharing properties, then install the access application on each of their stations.
They need to each be able to use the database when they need to and read or add data, reports etc.
I am using access 2003.
Thanks
Dave

I maintain a database that is used by several people in my office. Only about 4 different people actually use the database but I would like the database to have multi-user support. As of right now the tables, forms, modules, etc. are all in a single mdb file. Can someone recommend a method for making this database accessible to several users at once? My main concerns are accuracy (changes commiting in the proper order) and low chance of corruption.
