I have prepared an access database on a shared drive location(lan) with 5 tables. The main table has over 110 fields and is linked to a form. On an average the table stores 12000 records, which are updated via a form.
Normally, 7 users work on this form and do add/change/delete operations on the records.
The frequent issues I face are:
Corruption of records.
"Could not update, currently locked" errors.
I have constantly tried compact and repair option, but the same does not give required results.
I have two database applications and they are: - the (A) application is for administration use. - the (B) application is for normal users use.
the idea is that: I made the (A) application for administrators who have full control over the database objects (tables, forms, queries, and so on ...).
the (B) application I have created for normal users who will have only to use forms to insert some data and display data only.
but the two applications has a respective table called "vacation request" table. where I linked them, so the both administrators and users can share the data.
The real question is that: How can I prevent the users from seeing the database objects in their application. I used the database options which have helped me in hidding the database objectives when the users open the application, but unfortunately they managed to access to the database objects by pressing the special keys.
I would like to have an access to the (B) application when I want to make some modifications to the forms and then lock it from users where they only have to use the forms for requesting vacations and view the vacations.
I have designed a database which I intend to split for multi-users to access from one front end icon on a shared folder at work. I have designed a form bound to cmr record table and on it a subform to another table where cmrs activities will be saved. The form has buttons to and blank controls.
User can create a new activity entry by typing into the blank controls and pressing the save button which saves to the activity table. the edit button extracts a selected records details (selected on the subform) from the activity table and populates the blank field for a user to edit and then hit save to save changes. The delete button deletes a selected record from the activity table. I intend to have multi-users either accessing, viewing and a possibly editing the same customer at the same time. The simultaneous viewing is essential but the simultaneous editing, though not desired is inevitably going to occur.
What I would like to know is:
1. Can you lock an individual record in a table or does the whole table have to be locked. E.g If Colleague 1 is editing Cmr A's record in Table1 can he lock it so Colleague 2 can view and edit Cmr B's record in Table1
2.Can Colleague 1 access/read Cmr A's record in Table1 to retrieve details toe the form controls if Colleague 2 is viewing or editing Cmr A's record in Table1
3. If record lock is possible, how can I initiate it in my example code below.Edit activity record Code
Code: Private Sub Edit_A_Click() 'Get Data to text box control With Me.R_P_Data_P_Subfrm.Form Me.txtrID = !rID Me.txtrID.Tag = !rID Me.txtrefNo = !refNo Me.cmbrpc = !rPC
I have a company wanting to asses my database and i am willing to show them but i need to be able to lock the database so that they can view it but cannot edit anything in it either adding deleting or plan editing. How can i do this.
As my username states, I am a rookie to MS Access. I built a database using Access 2002, I will distributed it to other people, I will like to lock changes to certain areas such as forms, design view, etc.
Can this be done? The help is greatly appreciated!
I have looked on the forums and cant quite find what im looking for so i wanted to ask you lot for help.
I have a database i have created.
It will be sent out to people to populate via a series of forms i have created.
How can I lock it down so that: 1) you cant access any of the database apart from the forms 2) Lock it so no one can get in to view the code anywhere or make any amendments to the forms and database what so ever
I am new at this stuff. So please excuse my ignorance. I created a database which a lot of my colleagues want a copy. I don't mind giving them a copy. However I don't want them to change the design or copy it to give to others. I don't mind them adding their records.
Is this possible to do? Or should I just keep the database to myself.
Does anyone know how to lock a database so it can be accessed by only one person at a time? We have several users using a 'local' copy of the same database and frequently synchronizing with a network copy. We want to avoid a situation where more than one person is trying to synchronize with the master. Please advise - thanks!
I have a call tracking database with 5 active users. Ocasionally the database will freeze, usually for several people at once. It will say: "Can not update record; Currently Locked"
The only way to fix it is to close and re-open. I split the database, compiled it and then created an MDE file to distribute. They are using copies of the front-end, not links. The database locking more and more every day. But we are using it more. After parusing the forum I'm starting to suspect that this is a problem of "Primary Key duplication" If everyone trys to create a record at the same time, would the database lock because we all created the same record at the same time?
If so, how do I get around this? Use something other than Autonumber for the primary key? Or is this an entirely different problem?
Have an Access database that is used by multiple users, the lock file seems to have vanished. Yet the database is in a read only state and still locked. How do I unlock the database? How do I find out who is locking it? How do I kick the person off is neccesary to unlock the database? Thanks.
why is it that as soon as you fix one problem another one needs dealing with :mad:
OK, the problem i have is that i have a BE/FE configuration database in a multiuser environment. I have built all the tables and the relationships in the BE configuration. In the FE configurations i have built the main forms to input data. It has no come to the point where i have begun to create the queries to allow reporting and data searching. And this is where i have a problem. I am trying to create a simply query and i do mean simple (at the moment i simply want 2 fields from 1 table and 2 fields from another table) no calculations or anything i just want it to display the data. I have tried creating this query numerous times and i keep getting the same error.
"The wizard is unable to open your query in datasheet view, possibly because another user has a source table open in exclusive mode. Your query will be opened in design view"
the above is the error i get when i use a wizard to create the query, after getting this message and going into design view i try to view the results in datasheet view and get the following error "Type Mismatch in expression"
If i dont use a wizard and create it in design view, when i go to view the results i get the second error message everytime.
If i create a query from 1 table only the query works without errors, but i always get errors when i have more than one table in the query.
Also i am the only person with the database open so therefore it is total impossible for the database to be open by another user in exclusive mode.
Anyone know what the problem might be or how to fix. Your answers will be very much appreciated.
Another baffling problem - there are far more traps for new players than I ever imagined. Any suggestions gratefully received.
I have a fe/be split database with multiple users on a network. All users have the same front end on their PCs and are either running Access 2000 or 2003.
Problem 1:
Some users cannot open the database at all, getting the error message "Could not open xxxxx.mdb - File already in use."
Problem 2:
Some users can open the database but get a message in the status bar saying "Recordset not updateable."
Other users, running either Access 2000 or 2003 have been able to use the database without difficulty. The number of users is in single figures and it is unlikely that more than 4 people have attempted to log on simultaneously.
The database default open mode is set to "shared", the default record locking is set to "No locks" and the "Open database using record-level locking box is checked".
I have been having difficulties setting the security for the database (see other postings on this site) and so it is currently unsecured with no password set for the admin user. Users are joined to their default system Workgroup Information Files.
My guess is that there is a setting on the Access installation of the user's PC that needs to be changed but this is only a guess - anybody any idea what I should try next?
I have created two DBs, one Back End, and one FrontEnd. My FrontEnd contains all the UIs/Forms, Linked Tables, and the queries fetching data from linked tables, and the Back End consists of all the Tables.
Now, in my Model, the BackEnd DB will be stored in a common drive and will be accessed by multiple users through same FrontEnd.
Now when I am trying to fire a query in FrontEnd (aka FE) DB, it is locking up the Back Up database. Even though I have set the RecordLock property to No Locks to query and the form.
I have access BD and every one use it through shared folder. My problem is in attachment ! , if i use the regular attachment filed in access there is one user only able to attach files and others can`t attach any thing until he finish.
I tried to do attachment through VBA like below which make it worse as it lock the DB so, no one can even open the DB and one user only access the DB .
Dim db As DAO.Database Dim rsParent As DAO.Recordset2 Dim rsChild As DAO.Recordset2 Set db = CurrentDb Set rsParent = me.Recordset
[Code] .....
How multi users attach files at the same time without locking the DB.....
Bottom line I'm in bit of a pickle, work has moved forward the migration of Office97/NT4 to Office2003/XP by 2 months (clever lot) and was hoping not have to cram for this question until at least 3-5 weeks.
I'm looking for pointers/suggestions because I now have to test in Access2003 Runtime on MONDAY!!!!
What it is, is:
I have a query which is a list of items that need to be worked out of 65,000. Of that 65,000, 20,000 end up in the query (Actually do need looking at after an Automated process) (it's adapting the query/process I think I need)
Query:
EntID - UniqueID for a household Applicant1 - Number lookup value for Applicant 1 Applicant2 - Number lookup value for Applicant 2 Qualifies - 1 = Yes, 2 = No, Null = Not worked.
That's basic building block of the Query which is Drives the main Form.
What I would like is a scenario similar to this:
Person A opens record 1
Person B opens record 2
Person C opens record 3
Person C finishes record 3
Person B finishes record 2
Person C opens record 4
Person B opens record 5 (he/she took a little break)
Now that's the way I would like it to work, but there will be other factors and this is where I'm all ears for anyone who is used to this type of system.
The problem I can't figure out is that the Main Form has several subforms, but none of the data is to be edited, it is there for visual purposes only. The users will be creating records via the Main Form through code, but not directly into any tables/queries with which I can use conventional record locking, that I can see.
My thoughts are that Person A calls up a record based on Min EntID and somehow locks it so the Person B looks for Min EntID Where not locked.
Please, please can someone point me in the direction of how to do it and more importantly the correct order of events? I have tried doing the Min EntID and locking the record, but while Person A is running the Min Query, Person B is running it also so they end up with the same record as B has the record on screen while A is locking it.
Also, In the real world Person B might open record 2 and think, nah I can't be bothered. I would like a proffessional opnion on whether C opens record 2 or should B be made to deal with it.
I think not given the huge time constrants landed square on my lap, I would get there with smaller questions, but I've spent the last 10hrs writing a Function, to get it ready for the testing lab, where the owner has changed the requirements 7 times and my head isn't working.
All or some help given will be GREATLY received. Any further information needed, just ask.
So with the help of many of you on this site, I was able to build my first Access database. Thank you all.
Now that I'm all done, I have one final thing to figure out.
I have incorporated user authentication into the database for a minimal level of security. Everything finally works like it should, however there is one "flaw" I have found.
In "Access Options" I have the login form set to open when the DB is open, and navigation and ribbon/toolbars are deactivated so only the login form and "Home" ribbon are showing when the DB is opened.
The problem with this, is that a curious user that shouldn't have access could get access fairly easily.
If they right clicked the "Home" ribbon, then left clicked "Customize Quick Access Toolbar", they could change the default form to whatever they wanted. Thus bypassing the login form and nullifying any security that it offered. Ideally, there should be no ribbons or toolbars. I just don't know how to get rid of them.
In OPTIONS -> Advanced I have the option Open Database using Record-Level locking ticked.
What is strange is record level locking works on Form1 (Form1.recordlocks= Edited) as long as Form2 has Form2.recordlocks = No Locks. If I change the Form2.recordlocks = Edited, Form1's locking becomes page level locking.
This is even true if Form2 is not open...
Additionally, Form2's locking is always page level locking if Form2.recordlock = edited.
I would like all my forms to perform RECORD level locking not page Level locking. How do I accomplish this.
I've been trying to resolve this issue for about 2 months now but no answers from the community.
I have a database that i created for our tech support team. I have split the database and have given the 3 users each a shortcut. I als e only installed Access Runtime on their machines.
The first user in pilot testing had no issues and we have just added the other 2 users. At first all was well. However, the 2 new users are now having periodic lock ups where they go to enter a new record and the dbase freezes on them. It seems to release itself in a few minutes, but this does not help my productivity.
My original user is still not having any trouble. Does anyone have any ideas of something that perhaps I missed? Everything I have read, suggests that 3 users should not have any trouble using a split dbase.
Is it runtime that may be causing this? I have considered going to full versions if need be, but then I would need to figure out how to lock it down better.
I have 4 questions (4 fields) in a form. 2 are drop down menu type and 2 are open text fields.I would like to limit the user from entering data in the fields if one has been answered. for example: if Question one is answered, question 2, 3 and 4 should be locked and should not allow the users to fill in anything. How do I create that Locking system?
I have some security issues going on all of sudden. I now have 2 Record locking information files on my drive. I have several users sharing the database. Any clues why this is happen?
I have an access file (a Form) that I put in the network and it's accessable thru a web site inside our company(intranet). I setup the database to be on shared mode so everyone can access it at the same time. The problem I'm having is that when someone open the file, access creates another file called "Microsoft Access Record-Locking Information" which still active even after users close the form and their web browser and this doesn't allow me to edit the file if I need to make changes. Is there a way to deactivate this record-locking file? The only way I found out to be able to access the file after someone used it, is having the user go into their Task Manager and delete MSACCESS.EXE from the Processes tab. Any inputs would be greatly appreciated.
Im a relative access newbie, and am updating an already created form. I want the user to be able to change the value in a field , then when they exit the field, for it to be greyed out, so that no more editing of the field is possible.
I know how to lock the field in design view, but I want the field to lock after the user has amended it. Is this possible?
Is it possible to access specific records from a Microsoft Access table without locking the whole table?. I have different processess accessing at the same time different records from the same table and I getting an execption, indicating the table is locked. Can any one provide me some help regarding how to access specifi records without locking the whole table in MS Access?
It just read in Access Help that if you have open db using record locking checked that you must open the database using the File=> Open command from the MenuBar. Does anyone know anything about this or can anyone comfirm this a s true?
