I have a client that is using a split database. I am working on an update to the program and need to transfer a table to the backend that has the correct structure and information included in it. My thoughts are to make a one time use program that transfers the table to the backend. I have seen DoCmd.TransferDatabase and DoCmd.CopyObject as possible ways to go.
View RepliesI've got a Split Database (Front End & Back End). So far it was all good until recent when a department placed in a different city (200 Miles apart) wants to use my application. The Application has gone very slow for them when they access the back end.
Things which I've already done.
Analyzed Tables
Analyzed Performance
The only best way I could think of is to have two separate Back Ends for both cities and synchronize them may be every hour or so. Is this possible and how much feasible is this? Or is there an even better way to accomplish this.
I have a database that I've created for someone else to use. It's split into a front and back end. The user will be placing the front end on her desktop PC and the back end on a network server.
She also will be taking the database home to use from time to time. My problem is that when the database is split, upon opening, it looks for the back end on the network drive, which is unavailable when she's away from the office.
Is there a way to tell the Access to look in a directory relative to the one it's in?
I'm trying to create a button that will open a save window so that user can select where and the name of a new backend file.
and create a new backend file from the one in use and link to the new open.
So the database I have right now is split, with the back end on our server. Everything has been going great, however there are several second time delays when loading large forms, queries, etc. I've heard that moving the back end to an sql server is the way to go for speed.All forms and queries are on front end of database. Tables are located on the back end which is sitting on the server.
View 7 Replies View RelatedSo a while back I created a database which I use to keep track of my companies large list of products. It is very simple only 3 tables, 1 query and 1 form. After running into a problem with copying and pasting updates on each computer in the office I decided to split the database on a network drive. This worked for a bit, however I had to add new fields and modify the form, which corrupted the file. Luckily I had a backup before the split.
As far as I could tell all I had to do was modify the backend file and make a new front end. However it seems like it is not as easy as I thought it would be. How do you modify a split database without corrupting the files or using a non-split copy?
I have a need to copy a table structure from an existing linked table in the backend
i have done this by
a) copying the table structure into a new table in the fromt ebd
b) exporting the new table into the backend
c) dropping the table in the front end
just wondered if there was an easy way to do this directly in the backend?
I have a database stored out on a shared drive at my company that multiple users connect to via a front end application that they save on their own hard drives. Recently I have noticed that the back end database keeps getting opened exclusively which prevents other users from being able to access the back-end database. For the life of me I cannot figure out what about the front end opens the back end exclusively and cannot find any plausible solutions I thought I could develop something that could force close a back-end database or disconnect all users from it?
View 3 Replies View RelatedI have an Access DB with a form that allows the user to select a new backend database. I can connect to the backend and then .refreshlinks but nothing on the form is updated. I have tried requiring the form but that doesn't do anything. I've tried loads of other things, refresh, recalc etc., but nothing updates the open form.
The only way I have managed to get it to work is to close the form and reopen it, then it shows the data from the newly linked backend database.
While it works, it doesn't look good but also there seems to be some problem with it because eventually it reports an error saying "cannot open any more databases" and when clicking OK comes back with "An error occurred while sending data to the OLE server (the application used to create the object" and a whole bunch of other messages.
I think it might have something to do with the fact that the form has a number of MS graphs open on it, but I'm not sure. Also, I can't track down a particular line of VBA code which causes this error.
how to update a form after changing the backend database.
Is there any particular reason I would choose to use
DoCmd.RunSQL "insert into...
Versus
CurrentDb.Execute "insert into.... ??
I am using an unbound form on the front end of my database to populate the backend tables (multiple tables). Some forms only have a few fields, while other forms have about 15 fields with 3-4 tables updating.
I am okay using the DoCmn.RunSQL , but I keeping reading on the forum that others chose CurrentDB.Execute and it has me thinking.
My database is stored on a network drive with only on front end.
I have table1 in my (Access 2010) database that has exising records. I have another table2 that after I run a query, it first deletes the data in table 2, then imports new records into that table. I run the import into table 2 on a semi regular basis but have yet to copy those records into table 1.
With that said, using either a query or VB, how do I copy all the (new) records from table 2 into table 1 without altering any records that already exist in table1?
BTW, Table 1 has a main form with a subform within it
I am using Access 2010 in a split database. The intent is to place the back end and associated linked files on a server and the front end on work stations for each user. The typical user will just be searching for information in the database not altering it. My current code re-links the tables once the path is known i.e. I have to hard code it into the global constant. Is there a way in VBA or utilizing VBA to read/write to an ini file (for example) that the UNC path would automatically be updated to a global constant in my current code that can be updated automatically based on where the back end is installed.
Global Const BE_DATABASE = "192.168.2.3FMCENFMCTABLES.accdb"
Global Const BE_PASSWORD = "***********"
Global Const BE_DATABASEPATH = "192.168.2.3FMC" 'used to open files
Public Sub CreateDatabaseLinks()

Dim ws As DAO.Workspace
Dim db As DAO.Database
Dim td As DAO.TableDef

I have an project with a split database. The data is stored in the database_be.accdb
I want to know which users are connected tot this database.
My database was working fine until I split the database and now I'm having issues with this function:
Code:
Public Function OpenFirstAttachmentAsTempFile(ByRef rstCurrent As DAO.Recordset, ByVal strFieldName As String) As String
Dim rstChild As DAO.Recordset2
Dim fldAttach As DAO.Field2
Dim strFilePath As String
Dim strTempDir As String
[Code] ....
It's getting stuck on the "strFilePath = strTempDir & rstChild.Fields("FileName").Value" line. The debugger says that there is no reord. The strTempDir is correct. I am assuming that the issue has to with linking to the database.
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 a split Database into Back-End and Front-End. I want to hide the Access Customize Option in my Front-End. I have tried to make the Database ACCDE but the option still appears to Customize the Access Database.
I also want to know why is it that when i make a Database ACCDE - some of the codes are not working properly???
I have a split db with tables in the back end and my forms, reports, code etc. in the front end.
I encrypted the back end with a password. That worked fine.
I deleted and relinked my tables to the encrypted back end. That worked fine as well.
I have a function that will disable the shift key bypass. If I run that in my front end db then I can't save it as an accde because I can't get to the HOME screen. If I save it as an accde first then I can't run my 'disable shift key bypass' function because I can't get to the modules!
How can I secure a split Access 2010 database so that the user cannot execute shift bypass on the front end or make any changes to the code?
So I split my database into a front and back end, now i wanted to add a table to the database. I created the table in the backend but I am not sure how to make it appear in the front end. I am using access 2010. I tried the link table manager but the table I created doesn't appear there.
View 4 Replies View RelatedAdding a field in Access 2007.
I am adding a exisiting field which is already available on a Global Table and would like to add it on a local table within the same database. Also bearing in mind the db contains main objects - Tables/Queries/Sharepoint lists/forms/reports
Whats the process in doing this? Once added how does the data get populated?
I was asked to create a table within an existing database using these SQL commands;
CREATE TABLE Vehicle (reg_no TEXT(10)
CONSTRAINT VehicleKey PRIMARY KEY,
type TEXT(10),
purchase_date DATETIME,
last_service_date DATETIME, mileage_at_last_service INTEGER);
I was told to save the query and check the new table had the required records in it.
I had huge problems when I tried to save the query and kept getting error messages like: "query must have at least one destination field" and "syntax error in field destination". This was strange since I was sure I typed the query exactly as it had been written on the worksheet.
Having not changed the SQL command at all it eventually worked when I skipped the 'save query" stage and just went to the "run query" stage. I still don't know why it actually worked in the end and why I kept getting error messages.By running the query am I supposed to just click on "RUN" or can I check the information first by looking at datasheet view?

Hi All,
I've developed a database that was working fine until I split it to use in a network enviroment. The problem is a make-table query that now make it's table in the front end instead of the back-end. I need to run a make-table query because the query uses a custom function which then causes errors when the query is accessed by a web form that I use.
The only way I thought of getting round it was to create a permanent table in the back-end which is cleared every time and an append query used to populate it.
Anybody any other ideas?
Cheers
My db is split into front-end and back-end. In the f-e's Relationships schematic, I can see the relationships as they were defined at the time when the db was split, complete with the one-to-many symbology.
I can add a new table to the b-e and set its relationship as one-to-many, enforcing referential integrity and cascading as I wish - and the schematic (in the b-e) reflects that.
In the f-e, I can then use the <Get External Data - Access Database> function to link to the new table, and I can add the new table to the relationships diagram in the f-e. I can also drag and drop to link primary and foreign keys (within the f-e), but cannot select one-to-many. I'm OK with that, as I understand that the relationship is within the b-e, and this is just a diagrammatic representation.
But I can see the one-to-many relationships between the tables which existed when the db was split, and I would like to be able to see the new table's relationships in a consistent fashion. Updating the linked tables via the Linked Table Manager does not do the trick.
Surely I don't have to split the database again in order to achieve a consistent diagram - do I ?
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
