General :: Split Database - Users Seeing Blank Forms
Apr 10, 2013
I have a split database consisting of an ACCDB backend helf on a shared drive, and a local ACCDR frontend distributed through email. I recently distributed a copy of the ACCDR to a user, and she says that the main menu opens fine, but when she clicks a button to open a form, the form opens but is completely blank. I've googled some possible causes for this (e.g. on Allen Brown's website) and none seem to be relevant, or would explain why this started happening all of a sudden. I can't reproduce this bug at all.
I have two separate database files, a front end with all my forms and a back end with all my tables. The backend is stored on a network drive, is there any way of being able to store the frontend on the drive with the backend? Users do not use the actual computer to store information or access files, everything is usually saved on the network drive. I have created a shortcut that launches the front end database in the read only kiosk mode.
I've got a database in Access 2007 that keeps track of client data for work. It's been working fine for about a month, and suddenly today other users can't change any information because the records are suddenly locked when accessed from their accounts.
I've already checked that they can't update forms, tables, nothing.
I've checked the database properties, it defaults to shared with no locks.
I've checked the properties of my forms - no locks.
I've double checked the permissions to the folder that the database is in - no restrictions.
I split my database and put the BE on a shared network folder. The users can access and change data on the database fine as long as someone else isn't using it. If another person is logged on and using the database another person will be able to open the database but if the new user tries to click on a button or go anywhere besides the main menu it says there is already a user in the database and wont allow the user to go anywhere. How can I fix this?
We have a database that is split. Every user has their own front end (installed via a .bat file so that the users always have a local copy of the most recent version), linked to a shared back end on a server. This seems stable and functional for us so far.
However, because our users are geographically separated, I don't actually know how many folks are using the database. I know the folks who contact me, but everyone in our company could use it if they wanted to.
For requesting funding, guiding future development, etc., I need to get some metrics:
Total number of unique users Avg uses per day
Total number of simultaneous users (daily, weekly, and monthly maxes and mins)
What is the best way to get this info? Write user info and a timestamp to a table each time a front end is launched? Are there tools for monitoring this sort of information?
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 haven't done any testing yet on splitting the database I'm working on but a question came up today about networking.
This database is going to be used by a few equipment operators to record machine readings on the manufacturing floor. There is a wireless network and we are in the process of confirming that the wireless signal reaches all the areas. The users will be using ruggedized windows tablets to enter the data.
The BE of the split database will reside on a network drive to ensure everyone that needs it will have access and it will be regularly backed up. etc.
Since there is alot of heavy machinery, there may be some spots where connectivity will be weak or non-existent while they are entering their readings.
The question is how will the runtime FE handle it if connectivity is temporarily interrupted?
i have created a database and just use the feature to split the database. i then set a password on the back end database. however now when i use a macro to open a form in the front end it won't open the form and just says incorrect password.
I tried saving my split database to a flash drive so I could move it to a computer that is connected to the shared server but it did not go as I planned. The back end with the tables works fine, but when I try to open the Form on the front end it says it cannot be located. I just want to take all the files I have (Should only be 2 front/back ends) and move them onto a new computer.
The database: is for tracking computer issues (this part is complete), also I need to show the on call roster (mostly complete)... This will also have a time sheet that I need to be completed once a fortnight, however I would like it to auto populate the staff members logged information (I will get into that a little later).
Question 1: I do not want the users to log into the database, however I do want the database recognise who they are from their windows logon details.
I am attempting to split an Access 2007 database. My company has two locations. From my location we are remote connecting into the server. While down there they are connecting directly. When I split the database, people in my location can use it fine. When people down there use it, they get a not valid path error.
This is because the network drives are mapped differently. I have been reading that the solution is to use the UNC for the back end file path.
I am new in database design . I did a database by access 2010 which contain form and tables and i want to split it to backend and frontend and then make then in website
I am currently working on an application where I am using MS access as my FE and working with linked tables to SQL server BE. I also have a few temp tables within Access that are not linked but needed.
1. What are my steps into making this into a SPLIT DB? I am assume the BE will have my linked tables from SQL and the FE will have my temp tables and forms. Is this correct? 2. Once I split it, then I can make an .ACCDE file for a Mulit User environment, is this correct?
I am trying to use VBA to backup the BACK-END of a split database (so I can automatically archive selected data). If I use FileCopy I get a message that the BACK-END database has not been found.Obviously I could 'unlink' the BACK-END, copy it and 're-link' it..Is it possible to copy the BACK-END tables(not just the links) into the FRONT-END and get at them that way?
I have developed a new database using Access 2003, which I need to roll out across various users. Some have XP, some Windows 7, and each of them has different size screens. I guess I will have to adjust the various forms to size to a particular users screen resolutions and sizes.
Is there any way of doing this within the database itself, or do I have have to adjust each form according to the local users PC specification?
I used to have a handy tool called LDB Viewer or something like that with which I could see who is using my database. Now I've upgraded to MS 2010 is there a way to do the same?
I'm an absolute novice at Access. I have a very simple (yet sufficient) database that lists our company's projects, tasks associated with those projects and when to invoice.
Our company consists of myself and my business partner. We both work from our (separate) homes. Our project files are stored in the cloud. This works well. We have investigated a server in the past, but found it to be cost-prohibitive and unnecessary for our business.
Is there a way that my business partner can have the Access database running at the same time as me, and make additions/modifications? I don't know how this would work in terms of updating/saving.
I am about to allow users to access a database I redesigned for others to use.I am trying to save it as an ACCDE so they can't mess it up. The database is very very simple.6 tables each with only 4 fields or less... and none are related to one another
7 forms. 1 report. 0 queries... it's just a SKU generator.
When I attempt to save as ACCDE I get an error that reads."Microsoft Access was unable to create the .accde, .mde, or .ade file.This error is usually associated with compiling a large database into an MDE file.* Because of the method used to compile the database, a considerable number of TableID references are created for each table.* The Access database engine can only create a maximum of 2048 open TableIDs at one time.* Exporting a database as an MDE potentially can exceed this limit if the database has a large number of objects (table, macro, form, report, etc).
There is no accurate method to estimate the number of TableIDs the Access database engine uses during the process of compiling a database as an MDE.* However, each VBA module and each form uses one TableID, as a result, if the database has 500 forms, and each form's HasModule property is set to Yes, as many as 1,000 TableIDs are used."
I have a split database with the backend on our server. When I go to my server and look at all the open files on the network everyone who is in the backend shows up twice. One has zero locks and the other has multiple locks.
I have split the database, with the back-end residing on the server. Only 1 other person is working in Access right now; she's verifying the data. Today she's working directly in the back-end, could this be the problem. If it is, I'm going to have to create a front-end for her quickly.
My problem is this...I'm working on queries and forms so that the scientists who will ultimately be using this application, won't be able to go in and inadvertently change something in the tables set-up. When I'm in the back-end main data table, it says I have 2723 records.
When I create a front-end query to query all the records in that table, it says I have 2160 records.
The input form that I created with most of the same fields as the query (created BEFORE I created the query...I'll have it pull from the query now instead of directly from the table) also says we only have 2160 records.
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?
Is there a tutorial on how to split a database so that it can be uploaded to a sharepoint site and one part of it allows updates and the other part only viewing?
