Data Locks/Record Locks? Question
Feb 12, 2007
I have a database that is used in a retail environment. I cant figure out what causes the locks of data.
I have an invoice (form) that it is filled out at point of sale(customer table). The middle section of the invoice (subform) gets the data from an inventory table.
The issue that i have is that often the subform locks up and does not allow the user to enter new data or make changes? It generally happens when they disconnect from the remote server, or loose connectivity???.
We use remote servers, using remote desktop connections.
The way i fix it is I take a backup database and move the tables out of the locked database into the new one. I just cant figure out what to do about this....>??
When you open an invoice at point of sale if the record is locked No line shows up on the subform to fill in. See image below.
When its fine the line will appear to take in entries.

I have a multi user database that has record locking turned on at the form level. If one user is in that form making changes it locks that record so no other user can make changes. When another user tries to edit the same record they are only notified after they hit save. Can you have them be warned that this record is locked before they waste time entering data?

Hi,
I'm trying to run a very simple update query on a table that has around 200,000 rows. It is only updating one field with the month based on a date using the Month() function.
It keeps saying File sharinglock count exceeded. Increase MaxLocksPerFile registry.
Any idea's on how to do this? The online help within Access is pretty vague.....
I'm also surprised this has happened as I've run update queries on tables with several million rows in before and never had this problem. I have compacted and repaired the database and moved from our server onto the hard drive of my laptop where there is more than enough disk space and with 2Gb ram there should be enough RAM as well.
Cheers

USING ACCESS 2010..My user has reported that his caps and num locks gets switched off when entering a particular form and after testing he's right!!
I've googled this and it seems that sendkeys is/could be the culprit.I do have sendkeys in the code so how do I get around it other than not use sendkeys? Can I switch num lock on in VBA?

I've developed a ASP.NET website which connects to a secured access database (user/pwd combos with an .mdw file) and allows users to enter data into the database. After the "due date" the system is locked and the database is transferred to a local computer via FTP for processing. Using a VB program and MS Access Reports, the data is printed out in a convenient format and distributed.
Recently, the more users that use my system the more frequently I've encountered problems with connecting to the database. I've been told that access databases are not designed to be used in a multiuser environment and that I should use MS SQL or mySQL instead.
My users report occasional errors and the debug information on the error page shows an 'unspecified error' prompted by a OLEDBConnection object's open method. Secondly, occasionally in the FTP site I see .ldb locking files with 10-20 locks on the database and the .mdw file held by the web application. I'm using a utility class that connects to the db in the constructor and closes the connection in its finalize method.
Code:Protected oConnection as OleDbConnectionProtected Sub Initialize() sConnString as String sConnString = "Provider=Microsoft.Jet.OLEDB.4.0....the rest of the connection string with data source and passwords oConnection = New OleDbConnection(sConnString) oConnection.Open()End SubProtected Overrides Sub Finalize()oConnection.Dispose()End Sub
First, is there something wrong with this code? Is it not being run at the initialization and finalization of each page load? Secondly, is there any way to avoid db connection errors without moving to ms sql?
Thanks

We are developing an Access 2010 database that is to be served using MS Server. Currently we have Windows Server 2008 R2 Standard SP1 64bit with Server Manager Version: 6.1.7601.17514 SP1 on a cumputer with 8GB RAM and an Intel Celeron G550 2.6GHz processor. All software is up to date with MS updates.
We are having a problem with dropdown lists that have too many items to show in the drop-down window so there is a scroll bar. If I click on the down arrow and open the drop down list, and then click on the scroll bar, the access window locks up. If I only click on a choice in the drop-down, but not the scroll bar, it works fine and does not lock up. Once access is locked up, I can click on another window on the desktop and then Access becomes active again. This does not happen on windows 7.

I have a form that uses a multi select combo boxes. When more than one person is in the database, if a user is updating any of the multi select combo boxes, it locks out other users from making changes to those fields on different records. Looking for solution so that every user in the database can make changes to those multi select fields on their own specific records?

I built an info application for a friend in business. Its based on a kiosk style menu with selections, and when a button is clicked it executes "FormOpen" and brings up a second form with the results in it.
Its important for this application that they are two seperate forms which display the results, lets call them form1 and form2 for this exercise.
My problem is that when form1 opens form2, it LOCKS form1. And if you are to try and select a list menu, or click a button on form1, when form2 is concurrently open, it 'beeps' with no function. Whether it be by .disabled or whether its some sort of record lock (to stop a person from editing in two places at once), I'm not sure.
Basically, form1 never needs to have records updated, its the kiosk remember ie. form1 serves as a menu. But when form2 is open i would prefer it if they could could still click buttons on form1 to execute filters for the query i have on form2.
I've tried fidding around with the .disabled property on form1, and then i also thought about the record lock and tried DISABLING data entry on the first form so perhaps access could work around. Nothing has worked. There is also nothing in the book that i have on access.
Please help!!! You will be much loved. Even if you just tell me its not possible then i can sleep easy.
Kind Regards
Jeremy

I am working on a database and i have notice after making a form that when i enter a record using a form if i enter incomplete data on the form access automatically save that record and generate a id for that record.
For example I have a table that contain
StudentID,StdName,FatherName,DOB,Adress,Phone
And I have created a form for that table that also containing these fields.
Here I want to do that on the form I want a "Save" button , and the purpose of this button that when I click on this button then MS Access Save the record and then generate the ID for that record and if i close my form without pressing "SAVE" button access do not save that incomplete record.

Hello eveyone . . .
i am attempting to create a VERY complicated query . . . it's sort of confusing:
I recieve data from an outside source and it is up to us to format it for our own analysis . . .
i have fields:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
The fields we want to focus on is "AccNo" and "TestCode"
Now i want to filter based on this condition:
If "AccNo" AND "TestCode" BOTH have duplicate data in a record. Show that record only once. Remember. . . "AccNo and TestCode, both these fields have to have duplicate data in a record.
Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456.....CBCA
CAPT.....M566679.....John Blue.....123456.....CBCA
the example above should only display once because of the repeated AccNo and TestCode
Example:
MethodCode..... AccNo .....PatientName.....MR..... TestCode ..... etc, etc
CAPT.....M566679.....John Blue.....123456..... CBCA
CAPT.....M566679.....John Blue.....123456..... LIPID
the example above is just fine because the TestCode is not matching
How do i create a query to accomplish this? someone please help, i've had troube with this for the passed couple weeks . .. .

I have an application that enters candidates in, who apply for a job.
I found that I can enter a candidate in, and if I dont enter at least an address type or phone type ( giving that candidate an address record, albiet a blank one (just a type of address) and a phone record) then the candidate wont have a sub record for addres or phone at all.
This is hurting my reports. They are set to pull the primary address and phone only, as we dont need to have 2-3 contact information for a candidate on a report This is how I found out that I had blank address and phone for some test records. I need to be able to check when a person does a number of things, that at least the combos for phone type and address type have been chosen as something. This will ensure that they have a primary address and phone, as I have code that takes care of all that. I tried putting the following code in the form's before update, but since it is calling to a subform, the minute I tab TO the address combo, I get the message. The form is updating before I get the chance to skip the field.
Here is the lay out. A user can enter in candidate, their address, phone, application and activities. Address, phone, applications and activities are all sub reports on a tab control. The user should be able to move freely within any record, and only be bothered when they try to leave, if important information is still empty. I dont want to control how they enter ('you must enter this first!' lol) just that they do enter it in the end.
What I want to do is check when the user is leaving a record.(closing form, going to another record, clicking the search button that opens another form etc) if either combo is empty (no primary contact info) then it gives the message and goes back to the combo that is empty.
Here is the code I have. If anyone can help me find the right place to put it, I would really appreciate it. Thank you,
If IsNull(Me.[subAddressEntry].Form![cmbAddressTypeID]) Then
msgbox "You must enter an Address"
Me.[subAddressEntry].Form![cmbAddressTypeID].SetFocus
Cancel = True
ElseIf IsNull(Me.[subPhoneEntry].Form![cmbPhoneTypeID]) Then
msgbox "You must enter a Phone"
Me.[subPhoneEntry].Form![cmbPhoneTypeID].SetFocus
Cancel = True
Else: Cancel = False
End If
If I can't figure this out, I am thinking of making a new address type and phone type. Call it "none chosen" and then make that a default selection. Then one would always be chosen...I think. I would like to avoid that though.
Thanks again.

The school director is going to input a date (by default today) and a subform will display all of the students who started before that date and haven't been closed as of that date. Next to each name, there will be 4 radio buttons (present, absent, holiday, hospitalized), which by default will be set to present. The director will go down the line, only needing to click when a student isn't present. At the end, she'll push a save button and the new records will be added.
My proposed method:
1. When the textbox with date input is changed, the subform (or just form and I put the textbox in the header?) will populate itself with a query based on student names whose corresponding startdate and enddate work with the inputted date.
2. The subform will be in continuous view so that it kinda looks like a data sheet but it has radio buttons rather than just spreadsheet cells.
3. When the save button is pushed, some visual basic code in the background will look at record 1, grab the student name and selected radio button value, and add a new record to the AttendanceRecords table with the name, attendance type, and date. Then the code will move to the 2nd record, rinse and repeat until it goes through all of them.
Questions/problems:
1. At its core, is this the Access way of doing something like this? Is there a simpler, more efficient, or generally smarter way of doing attendance?
2. How is step 3 going to work? I can look up how to add new records to a table, but I'm not sure how to move around from record to record collecting corresponding data.
3. Since the AttendanceRecord table uses studentID and typeID rather than actual names and actual attendance types, what's the easiest way of adding the new records with that data efficiently? I'm thinking of making the RecordSource of the subform some sort of linked up set of tables such that if I'm looking at record 1 and the name in the textbox on the subform is "Bob" I can just reference studentID in the background without needing anything on the form at all with studentID?

I have been searching all day for a solution. This is my first time using Access so a lot of this goes over my head. I'm currently running Access2010. I have a form that I am using for when people take office supplies and we can generate a cost per department. All of the Tables, Query and Reports are set up already and surprising work. My form fields are:
Date Created (automatic current date)
Quantity
Item Code (Combo Box that shows Item# and Item Description)
Initials
Department (Combo Box that shows Dept# and Dept Description)
RefCode
Remarks
I am trying to get it to where when I enter a new record it will autofill with all fields expect "Item Code" from the previous record until I change it.

I need to add two previous record fields together in a query. I have attached a picture to illustrate.
The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.
RunningBalance is calculated as follows:
Code:
RunningBalance: IIf([a].[StudyYears]=[ReserveParameters]![StartingBalanceYear],CCur([ReserveParameters]![StartingBalance]),0)
Bal is calculated as follows:
Code:
Bal: [AnnualContribution]+[InterestIncome]+[Inflation_Adjusted_Expenditures]
How to go about adding the two together as in the picture?
Is there a way to do this relatively fast, as well as keeping the query updateable?

I'm trying to get a DB to move records simultaneously using a command button. The records are setup with check boxes for example: one column has a check box for 1 Year Ratio the next column has a check box for 2 Year Ratio and the third column has a check box for 3 Year Ratio.
How can i move the information out from 3 Year Ratio into another table and then move 2 Year Ratio check into 3 Year Ratio check box and 1 Year Ratio check into 2 Year Ratio check box by using a command button.

I'm a novice with Access but I thought I would use Access rather than Excel to record fuel use for our vehicles because the reporting functions should be more powerful.
I have set up a table where I input date, vehicle, member of staff, mileage of the vehicle and the cumulative reading from the fuel tank meter. I thought it should be simple enough to calculate the fuel used each fill by taking the meter reading away from the reading on the previous record, but I cannot find a way of getting Access to do this.
I am missing something obvious or not?
Thanks,
Henry

I have two subforms on a tabbed page. Both subforms read/write data from the same table. The first subform is in dataset view and consists of 5-6 fields on the line containing class information. The second subform consists of two memo-type fields where users can enter comments. The fields from both subforms should be written to the same record in the table. The problem is that
the information from the second subform is being written to a different table record; it is creating a new autonumber. The data is being written to two separate records instead of being combined into one.
How do I link the two subforms so that the data gets written to the same record in the table so that the class information and it's related comments stay together?

Before I start I must say I’m not a coder (not even slightly). I’m just trying to reverse engineer a little access database to speed up order processing. The guy who created it has left :(
It’s a customer order database and at the moment if there is repeat business it requires manually copying over data such as name, address etc. from their old order. Is there some way to create an order from a previous or (ideally) currently viewed order?
This is the code for the “Create new order” option:
Private Sub Command93_Click()
On Error GoTo Err_Command93_Click
DoCmd.GoToRecord , , acNewRec
Exit_Command93_Click:
Exit Sub
Err_Command93_Click:
MsgBox Err.Description
Resume Exit_Command93_Click
End Sub
Is there something I could add that would copy and transfer the currently viewed name/address to a new order instead of just a new blank one? Is it even possible to copy/transfer data from currently viewed text boxes to a new order? Maybe there is a better way to do it?
Thanks :)

In my database I have all my clients information in the [Main] form and all their transactions / debits / etc. in a subform [Transactions] in datasheet view. My question is how can I have the subform automatically scroll down to the last record (or to a new record) so the user doesn't have to scroll down everytime a new client is viewed?

I have a table that has records of accounts, actions taken, and operator ids. Unfortunately, the records are incomplete. The report was written poorly so that there is a row that contains data in all three fields for all subsequent rows there is only the action taken, no account or operator. So my table looks like that the records below. As you can imagine this means that I cannot write any useful queries on what happened on various accounts. How I can append the account number to every row that pertains to that account number?
Account
Action Taken
Operator ID
1234
Act1
1
Act2
Act3
Act4
1235
Act1
