Modules & VBA :: Linking Back End Database With Password?
Apr 28, 2014
I have a Back end (with password) which resides in a netdrive while the front end is installed in each individual users desktop, the problem is, some of the users netdrive was mapped in a different way (different letters..some are J others are G). I'm looking for code that I can relink the database to the front end in runtime, I did try to look in the net but I can't find anything that I can put the password as parameter.
this sample code from Dev is good, but i got an error because the database requires a password.where i can put the password?
Code:
Function fRefreshLinks(NewDbName As String) As Boolean
Dim strMsg As String, collTbls As Collection
Dim i As Integer, strDBPath As String, strTbl As String
Dim dbCurr As Database, dbLink As Database
Dim tdfLocal As TableDef
I have a database already split and I wanted to put a password on the back end. When I open up the front end and try to navigate through the forms it says "Not a valid password".Is there somewhere I need to go / something I need to do to link up the two now that a password has been created?
I have designed a split database( with back end and front end), I am just wondering what would be the best way to put a password for both of the back and front end.
I have built a Database links to multiple back end databases. The whole database is completed, and I have to share it across the company, so I have placed the Database and all of the Back End databases on a "public" shared drive. I have the "public" drive stored as my Q drive. So when I link to the back end databases, the path it stores is Q:DatabasesDatabase.accdb
However, the problem is that not everyone will have the "public" drive mapped to Q. It's possible they could have it mapped to P or A or whatever. So if someone has their "public" drive mapped to P, this database will not work (since Q:DatabasesDatabase.accdb would not exist for them - it's really P:DatabasesDatabase.accdb).
Is there a way around this? So that instead of it mapping to the relative letter (Q or P), can it just refer to "public"?
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 trying to open a database with a password (I know the password) from another database however I cannot work out how to do it. I have been using this code to do this to open databases without passwords for a while.
I am using Access 2007.
Code: Private Sub Command36_Click() Const cstrClientFEPath = "G:Templates" Const cstrFEFile = "db.accdb" Dim intX As Integer 'Utility var
Can I create a table in the back end of my database using VBA in the front end? My client is using this system and I can't easily go to their location. I need to create a table on the back end and have it available in the front end applications. My thought is to create a front end only for the purpose of updating the backend with this new table. My idea is now to have it open with a button for the user to click - this will add the table to the backend with the required fields, confirm the update was completed and then close. This app then would be trashed so it would not be run again. (Though I would put a check in the VBA that if the table existed, the user would get a message box and the coding stopped to avoid overwriting the existing file.)
And once the table is created, is there a way to programmatically link it to the front end. I will be providing a new front end with this update so I could add something in the new version.
I have code that from DB1 opens DB2 and runs a Function in DB2.
The DB2 function produces a Boolean result that i am trying to get back to DB1 without success. Below is the script.
Sub Test22() Dim AC As Object Set AC = CreateObject("Access.Application") rc = "K:ARSHRAutomation_ProjectsMikeFEDB2.accd b" AC.OpenCurrentDatabase (rc) AC.Visible = True AC.Run "SendVariable" End Sub
Because i am using AC.Run "SendVariable" i cant find a way to get the value of SendVariable!!
I'm using the DoCmd.CopyObject method to copy a table from my front end db to my back end. My back end db is password protected and it keeps prompting me for the password. Can I somehow send the password in code so that the user is not prompted?
Hi guys! I have a front-end (FE) linked to a back-end (BE) db. I have added a password to the BE, but the knock on effect is that the FE won't work now. Just says 'Invalid Password'. I'm using MS Access 2002.
Any help would be appreciatted.
(The password is to prevent unwanted users from deleting data on the BE on the server)
I was wondering if it was possible to link random external tables to the Active Database through VBA. I would like to run the code that would open up a dialog box that would let the user select the database as well as the tables within that database that the user can select to link to. I am able to select the database and but not able to select the actual tables. The tables will be random so I can't make a constant statement for a specific database.
I am looking to automate the process of linking my Access DB with an ODBC connection to an SQL DB with VBA (unless there's an easier way to do it?) - some sample code - if this is possible at all?
Firstly thank you for your help, this should be a simple one I hope, but is cracking my head on the wall. Have searched and searched and can't find an answer.
I have an Access Db that is not password protected, but is asking for a password. It opens on any other machine fine?
I think my version of Access is playing funny buggers with me, any suggestions?
I was trying to implement some security on this Db, which is why it happened I'm sure. I ran the security wizard, set-up two users and admin with passwords, I have the output file to "recreate" something too.
Issue is, I then copied this Db to another computer for use on there, it worked without a Password, so didn't need to worry about it, now I can't open any Db on my machine??
I had posted this in another area but didn't receive a response and my whole project has ground to a halt until I sort this out :(
I have made a database with front and back ends. Now I wish to be able to use the front end over the Internet but the IP address of the back end keeps changing weekly because of my ISP. Now I have made a splash screen at the start of the program which asks for the IP address and when this is entered the front end links to the back end - but I can't get the code right for this
The code I have at the moment is embarrasingly wrong so I'm not putting it up here
The code I have at the moment has a box that asks for user to enter the IP address - I need it to use the IP address to enter the database at ip//data.mdb
I know there are posts on forums all over the internet on this topic, but it is just one aspect in particular that I would like some simple advice on. I have worked through user-level security suggestions online and made a test back-end database that has a user and a group, named "Developer." All of the privelleges are activated for Developer. Developer is the only user who can access the data of "Table1." I've created an RWOP query that retrieves the data from Table1, Developer is the owner of this query. I've also created a front end and tried to create a link to Table1; which is denied, as I had hoped it would be. My question is this: How should I structure my front-end so that users can retrieve data from this query, but cannot obtain the data using a different front-end?
I am developing a 2010 database which is split. In the back end I am linking to csv files - with a new file every month to link to.
What I would like to do (and have not been able to find a way to do at all so far! ) is each month to add the new table link in the _be and to be able to choose it in the front end user interface to view reports on, without having to "re-programme" the underlying queries to use the new linked table.
Have a database with a back end that I have been working on. The database resides on a USB at the moment. I was ready to deploy and now when I try to re-link the back end tables, I repeatedly have the following error: "Your network was interrupted. To continue, close the database, and then open it again."
At first I thought this was something to do with the network, as I was moving it to a shared network drive. However, I can recreate the same issue using someone else's computer and using my USB (although it's mapped to a different drive letter). I've tried a few things, including recreating the back end by importing only the table structure, but still no luck.
I 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.
I did a search in here as well as Google to figure out why when I relinked the front end to the back end after adding 2 tables to the back end that the tables did NOT show up on the front end. Only the original tables that I began with.From what I have read there are different ways to do it. One suggestion on here was to create the table on the front end and export it to the back end. I guess I will have to do this going forward.
But my question is, after searching pages upon pages with no luck, since I already have the tables in the back end how do I tell the front end to find them and link them?
My question encompasses a front end connected to multiple back ends. It is probably a mundane point, but reading a few articles didn't seem to touch on it.
By this, let me toss out that I am thinking of the personnel where I work when I say 95% have a hard time using email and MS Word, let alone mundane functions like find a file, etc. As such, I have to make my front-ends extremely user friendly.
With that in mind, when developers have multiple back ends, what are thoughts about the best way to relink when required? Even when there are 'more sophisticated' users? Security not an issue or is an issue (inasmuch as can be handled in access)?
Ex: Large corporation with a multitude of user ability. Large database with say 3 different back ends.
I was thinking about keeping a front-end table with each table name and UNC path, hard coding paths to corresponding table names, etc.
Personally I don't have a need for multiple back-ends, but the question came up while reading.
I'm trying to set up a simple query that links four tables. However, the tables are extremely large, all in excess of 1.5GB each so I had to split the tables up into four separate DBs. I've tried the following with no success:
1) Link the 4 tables in the DB which contains my primary key. This quickly inflates increases the file size above 2GB and won't let me go any further.
2) Build a remote query to connect the four tables. This looked promising until I tried to run the query and it became evident that it only knows to point to the last database source that you specified.
I'm running everything locally on my C drive. The data source are simple text files (1.6 million rows) from the FDA website.
Cannot open back end database. There are no other users logged on Tried opening it in open exclusive mode but still error message. Front end on number of desktop PC's. Back End on server. I need to get in design mode on back end but won't let me. I get logon screen but when try to log on get message below I can log onto front end ok.
Error message something like.
* You do not have perimission to open or enable database * You must have open/run open/exclussive administer permissions. * Request other users to log off e.t.c.
I need to take my database 50 miles to a factory site so that an engineer and I can review/modify all the records, ~450 so far.
Can I copy the front end and back end files to my laptop, review edit the data offsite, and then overwrite the back end file on my server when I get back? Are there any issues with doing that?
Does anyone know of a way to make a database back up by a click of a button in a main form in the database? (so a customer does not have to go tools/database utilities/back up database)
