I need some code that checks if i already opened the database. I can't use the /EXCL option because 10+ people are also using it.
I had this code when working with Acc97 but i seem to have lost it.:(
Hi,
I created the database, which shared by multi-user. But, my user have a problem to open it. When user1 open the database, user2 cannot open it, I did not remember the error message, it is said that Admin (computer name) prevent you to open the database. But, if the user1 switch another application program (the database file is still opened), user2 can open the database, then both users can access the same database file.
Why do we have this problem? How can I fix it?
Hi-
I have a form in a database that is just a look up form (you cannot add or delete records). How can I prevent this (see below or attachment) from happening?
************************************************** *******
'FormName' has been changed since the last time you opened it, either by another user or because another instance of it was opened on your own machine.
Do you want to replace the changes that you or another user made?
*To save your most recent changes and discard the user's changes or your previous changes, click Yes.
*To save this version of the object with another name, click No.
************************************************** *******
What's the best way to handle multiusers and forms? The database is split but sending the front end to all users is not an option. I've tried different settings thru the Record Lock...Locked fields...Allow Edits/Additions/Deletions...and we still get this message. I've tried adding 'DoCmd.RunCommand acCmdSave' to a timer. It doesn't help. I am at a total loss...does anyone have any ideas?
Thanks,
Derek
I'm using "Application.FollowHyperlink" to send parameters to a remote application.
Each time i hit the enter button an 'After Update' event opens a web page.But i don't want the web page to be opened.
is there another method to send parameters over the web without opening a web page?
Hi,
Does anyone have any ideas on how I might prevent a database from being copied. I have an application that I have set up with a number a tools to prevent exporting to an empty Access container, and from accessing the database design via the ShiftBypass feature, but the database can still be copied in its entirety. In some situations I would like to be able to add a feature to prevent this. Any suggestions?

If you are to sell a db. What have people done to stop one person copying it to their mates.
I have a way in which they send me their name,lastname and email. I then have a separate db that genertates a code based on a maths calculation. The users db does same calc. Then a comparison is done. if they match the code they entered goes green. if codes not right it goes red.
I also have macro that swap tables round when run. so by default its limted to 10 records. When swapped its unlimted.
I just cant link the 2 functions. Ideally some way it will see the green code and then run the macro to swap tables to a full db.
Then the customer has a full db and is also tied to their name etc...
Is there away in which I can protect an access 2007 database modification with a password.I'm doing this because I would like to prevent my client from modifying or having acces to the database's back end system (db), I would just like him to use forms and nothing else.
View 3 Replies View RelatedI have a table called tblDeliveryOverview and a table called tblPurchaseOverview in the relationship there is no link between each other but i've used a query to link the one field from tblDeliveryOverview to tblPurchaseOverview.
How can i prevent a record update from happening when i update a record in tbleDeliveryOverview and the same gets updated in tblPurchaseOverview, which i don't want to happen.
I have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?
I am supposed to make a database for a hotel system, how I could prevent double bookings.
My Reservation Table has the following fields:
Reservation No. (PK)
Room No. (FK)
Customer ID (FK)
Payment ID(FK)
Reservation In Date
Reservation Out Date
Together with preventing double bookings is there a way automatically that can mark in the Room Table, the status as "available" or "booked" automatically by looking at the date today?
I have built a database and within it my queries I use for reporting make tables in a separate database. This allows me to work in my data base and update info as needed. My problem is that my make table queries wont run if anyone has one of the report pivot tables open. I have added macros to all the Excel files that pull from the reporting DB but I still have several times when I cannot update because someone is using the pivot table, Is there a way to allow me to update the report DB's while the pivot tables are open? I have tried using manual refresh methods and disabling auto update on open but the result is the same.
View 2 Replies View RelatedI just finished a small Access-2013 database (accdb format).
Now I want to make it available to users.
How do I make an 'executable' (meaning that tables, forms, ... cannot be opened in design mode)?
Twice a year, a database of mine is accessed and put too use by various staff within a time range of 1 week. the database is on a shared drive and in a location which can be accessed by all.
The staff access the database from different workstations and in some instances at the same time.
This has only led to issues in the database being copied and then confusing staff on what database to click on thus i have 2 databases which i then have to sift through and copy/paste into the correct one.
I want to know the best way i can:
1) Prevent multiple users accessing the database at a time.
2) making a copy of the original and typing into a separate database.
I am having some major problems so i thought i would ask you guys out there for some help because i am starting to bang my head against a brick wall.
I have a simple database, well i have 3 but the problem is only occuring on 1. each of these databases sit in a shared folder on the company network. I am trying to allow multiple users access this database but every time a second user tries to open the database they are unable to get access and receive this message
The table 'MSysAccessObjects' is already open exclusively by another user
However i have set the default open mode to be shared.
can anyone help as i really need this database to open in shared mode.
Hello to everyone!
This is my first post but I am reading this for a while now and I learned a lot from this site. Now, I have a problem which I cannot solve and I hope that you can help me with some advise.
I designed database for production proces calculation and for warehouse management. I have BE and Fe which are on server and every user has the copy of FE for himself. FE is also on server. Maximum number of concurent users is 3. The problem is that sometimes I get wrong calculations.
For example, when someone click the button for finishing the production process, calculation of production cost goes wrong. But, that is not happening everytime. Let's say one of the 10 calculations goes wrong. I tested aplication localy on my computer and everything is working normaly. I also tested the database in network enviroment (in my house, BE on one and FE on second computer) and everything is also working good.
I have to mention that this factory is rather old and we are constantly experiencing power loss or voltage disruptions. And also I have to mention that network cables are not installed profesionaly. We bought several aditional UPS devices to secure the network from voltage disruptions and now I will test the database again. But, any additional help would be appriciated.
The strange thing is that I never get any kind of error message. Everything seems to work good, but when I look at the numbers I can see that some of the calculations are wrong.
And just one more thing. In my database I have some procedures which are based on several queries which are executed one after another.
Something like this:
docmd.openquery "Query1"
docmd.openquery "Query2"
docmd.openquery "Query3"
etc.
In some places I have up to 7 queries which are executed one after another one (first query deletes the data from table, second one makes the initial calculation, thirdone updates the warehouse data, fourth is calculating the new price, etc.)
Maybe this is the problem?
Thank you in advance,
gile2004
Sorry for my bad english... :)
I have split my db and distributed the FE to client pcs while BE is on the network. To demonstrate it i have 2 users , userA who has read/write rights on the shared folder where BE is while userB only has read rights on the shared BE folder. When userA opens the FE he can get in(writing userinfo in the table on the OnLoad event) but when userB gets in the FE opens fine EXCEPT he gets the error that there was an error on the OnLoad event, which i am fine with because userB doesnt have right access to the db yet. But now if the FE is closed by both users and this time when userB logs(read rights only) in before userA(read/write rights) he gets in with no error on the onLoad event but now if userA logs in he is shown the same error on the onLoad event!!!
i am totally lost as to what i have missed, can someome help? this is my code on the onLoad event in the FE:
Private Sub Form_Load()
On Error GoTo formload_errhandler
Me.InsideHeight = 5000
Me.InsideWidth = 10000
DoCmd.Maximize
Me.picBox.Height = Me.InsideHeight
'authenticate the logged user
Dim userName As String
userName = Environ("Username")
'check to see if username is in the SECURITY table
Dim objRS As ADODB.Recordset
Set objRS = New ADODB.Recordset
With objRS
.CursorLocation = adUseClient
.CursorType = adOpenKeyset
.Open "SELECT * FROM USER_SECURITY WHERE userID='" & userName & "'", CurrentProject.Connection
.ActiveConnection = Nothing
End With
If objRS.EOF Then
MsgBox (userName & ", access denied")
userAuthenticated = False
DoCmd.Quit
Else
userAuthenticated = True
End If
'at this point userAuthenticated is true
'log the user in USER_LOG table updating userID,dateEntered fields
Dim objCommand As ADODB.Command
Set objCommand = New ADODB.Command
Dim strSQL As String
strSQL = "INSERT INTO USER_LOG (userID,dateEntered) VALUES" & _
"('" & Environ("Username") & "',#" & Now() & "#)"
'save userEntered so userExit can be updated to the right record
'this will be used to query the right record when the user exits
dateEntered = Now()
Set objCommand.ActiveConnection = CurrentProject.Connection
objCommand.CommandText = strSQL
objCommand.Execute
Set objCommand = Nothing
formload_errhandler:
MsgBox ("Application has encountered an expected error")
Resume Next
End Sub
Dear All,
My company have an application that is using Microsoft Access for the database. The Application created by VB.
Because of server hardware failure, I have to reinstall the server (OS Windows XP) dan also the Microsoft Access.
Now my application cannot run in multiuser anymore after reinstall the server.
My applcation still can run in client computer but cannot run simultaneously in several client computer, because if one client computer has access the database in server, the other client computer cannot access the database, raising error inform that the database already open by other user.
what should I do to solve this problem ?
Thanks in advance.
i have a database that runs updates from within itself.what i need is, this database to then open a another database run a update query, then close it.

I not a big time DB person so please be gentle. I am a computer technician at a school district and need some help. We use a program called Aeries made by Eagle Software for out attendance and grading. It uses an interface that runs through Microsoft Access. There are two version of this software. One is the SQL version and the other just uses an Access DB on a server. We have the Access DB version running Access 2003. It was explained and accepted in the beginning that we didn’t really need the SQL version because of our district size which is some where around 1500 students. Our district consists of 6 school sites that are all connected with a fiber optic backbone running at 200mb with a minimum of 100mb to each desktop. We have a DB for each site running on 1 very beefy server in a central location. I’ve run my problem by the software maker and don’t feel like I’m getting much help. The problem I am having is slowness during login. When the first user of the day attempts to login the program is fast, about 10 seconds from “ENTER” to the main menu. As soon as that 1st user clicks one of the menu buttons anyone else who attempts to login to that database after that experiences at least 30 seconds from “ENTER” to the main menu. I’ve watched what files are accessed and when. I see that when the 1st user logs in, the systemxp.mdw file is accessed and a systemxp.ldb file is created. Then when the user clicks a button on the main menu, the sch05xxx.mdb is accessed and a sch05xxx.ldb file is created. The sch05xxx.mdb file is the main database file for any particular site. The “xxx” would be the site number. As soon as that file is accessed or that lock file is created the user will experience the long login times and sometimes as long as 4 minutes. I don’t believe this is a hardware problem. During the same time that users are slow I have made a copy of one of the databases onto the same HDD on the same server and as long as I’m the 1st person to open it, it will fly. The 2nd person is slow just like the rest. I also don’t think it’s a permission issue, at least not in the domain. I’ve run all these test logged in as myself and have Domain Admin rights to everything. I believe this is a “split database” with the tables on the server and the forms, and queries on the users computer. I read an article here, http://www.microsoft.com/office/previous/xp/columns/column05.asp called “Why is Access 2000 slow for more than one user?” Has anyone else had this problem or have a solution? If I’ve missed something and you need more info please let me know.Thank you for your time and I appreciate any responsesJohn

I have constructed a database in Aceess 2002 that four persons or more are going to work with. The users have there own computers in the same network. And they are going to work in the database at the same time the database is placed on a shared drive in the network. They must have the possibility to work in the same bookingformular.
Is there something that I have to think about so that everything works allright? I mean in the multiuser environment.
I had a lot of problems when rhe same people worked with an Access 97 database, But I hope that Access 2002 is better for multiusers. Is that correct?

hi,
am trying to create an application for a company that has a small call-center (strength 20). the db is in the central server and each caller sits with frontend on their computer.
the central DB is shared on the network which these 20 PCs are accessing.
The frontend: 1 Form only which is based on a query that displays records.
Form Lock property: Edited Records
Query Property: Edited Records
As the telecaller starts calling the customer looking at the records, they are not able to edit certain records as the respective record is locked by MS-Access when am sure that no other telecaller has opened the particular record.
Any help is appreciated.

Is it possible to have multiuser working on the same Access file?
View 2 Replies View RelatedWe are trying to cut down the # of spreadsheets we have and took a purchase tracking spreadsheet and turned it into access db (2010).
We have 3 sites, and users across network would be 1-2 at max might be in db at same time either recording a purchase, or updating a record on received items.
Can this cause corruption? Is there a way to set users up so it won't?
I know in older versions of Access there were shares that could be set up.
We recently put together a database for a call center. The file is located on a public drive, and all users seem to be able to access the file (at the same time) and input new information.
On one particular form, I've found an interesting problem: I've placed a button at the bottom of the form, which will go to a new record when clicked. The command to go to a new record is clearly in the OnClick event, however users in the call center have to click twice in order to execute the code. I don't have to.
We're using the same form, in the same file, opened with the same version of Access.
What's wrong with this database?
Thanks for any help you can give me,
Double-Clicking,
