How To Protect Access From ODBC Disconnects?
Dec 16, 2007
I finally got a chance to test the setup remotely, and it basically works with all the links I've set up.
I wanted to see how it would behaves should it disconnect or something and thus manage it gracefully.
First, I broke the network connection and tried to navigate to next record. Instead of getting a error message, Access just crashes. I'm not sure if this can even be trapped at all.
Secondly, I disconnected the connection then reconnected it. Access then tells me that the server has gone away, presuming because it's still looking to the old connection that was broken. Running the code to repair link fails also with same error. Can this be resolved with having to quit & restart Access?
Thirdly, I put a breakpoint on Form's Error Event but this doesn't seem to always to catch all errors. It does catch error if I tried to start up a form without the connection, but if it already has been started, and the connection was broken, the Error Event is never fired even though I get a dialog saying ODBC Call failed, then a zillion of dialogs saying Object no longer set or invalid. This would be extremely annoying to my end users.
Can any of those be avoided or fixed?

How I can protect the tables in a database and force the users to access them only through 'forms'. In other words the user will not be able to view or change the data in any table except through a form, when loading a form, the protection is diabled.
I need a total solution, I am not a powerful programmer. :confused:

I've been working on a large project for my employer for a year now (but software development isn't part of my normal day to day duties). Most of the work (around 70%) has been done in my own time at home. The company were going to buy a system that would be customized by developers at a cost of around $60,000. I've developed a solution that is probably better than what they would have got. At my last appraisal my boss said that it had been discussed that i would be rewarded if i delivered it. My question is:
Is it possible to password protect access to the source code? I'm working with Access 2003 just now. I know I can create a .mde file to prevent access to the source code but that would make further development difficult. e.

I am having a problem with an access database that is connecting to a sql server. When trying to run any queries it is very slow. I think the problem might be caused by the ODBC link and I was wondering if there are any alternatives to using ODBC to connect access and sql.

Hello all, is there a way to change an ODBC connection in MS Access. I have 4 ODBC connections that I can choose from (all of them from the same server), and instead of manually recreating a new ODBC connection everytime, I would like to point it to the new connection. The ODBC connections (Tables) have the same information, but throughout different times during the month.
Thanks in advance for your help.

Used to use these forums quite regularly and always found people to be of help, even started chipping in occasionally with the odd pearl myself :rolleyes:
Anyhow, having forgotten my username i'm back under a different guise and have a problem that i'd like some help with.
My company has a website running asp (not .NET) with an sql database backend. Basically we want a localised system to deal with order processing with daily updates to customer, order tables etc. I started to build something in VB and SQL but time is critical and once I work out this problem I can churn something out in access double quick time.
I can get the ODBC connection open to the sql database and import the data to Access 2007 table (ie dbo_tblOrders), but I then need to find/write some code to fetch extra records daily and append them to the EXISTING tables. At present data is fetched and added to a new table. Is it merge queries I need? If so how, and can I set it to only fetch new records?

Hi,
I want to import into an MDB table a csv file.
I'm trying to use the bulk copy table.
my function is:
SQL = "SELECT * INTO [my_table] FROM [ODBC;Driver=Micrsoft text driver (*.txt; *csv) ;Dbq=c:\;Extensions=asc,csv,tab,txt;].table.csv"
db.OpenEx( "Driver=Microsoft Access Driver .mdb);DBQ=c:\access.mdb;", CDatabase::noOdbcDialog );
db.ExecuteSQL( SQL );
when i run this function i get an error : "You cannot use ODBC to import from, export to, or link an external Microsoft Jet or ISAM database table to your database"
when i try to import in the same way a dbf file (insted the csv file) with VFP it's working well.
what seems to be the problem? how can i fix it? or if some one know how can i import a large csv file into access DB in an efficient diffrent way?
thanks ishay

I've moved tons of text files or Excel files into Access DB's but I need to take an ODBC report and put it into a table on a new Access DB. If I save the report as a text file I get boxes when I import it to the new DB. If I use Excel I have to make a new table each time. Can anyone suggest the simplest way to take an ODBC report and put it into an Access table. THanks

I am working on an Access 2002 database where one of the tables has five required fields making up the key.
There is a form that is linked to this table which is used for adding new records.
There is a close button on this form that has the following code in it's OnClose event:
"DoCmd.close"
When the form is opened, no data entered and then the close button is clicked - nothing happens.
It used to work fine, until I recently upsized the database into a SQL Server database and now it's all gone horribly wrong.
If I close the form manually by clicking on the cross, I get this
error:
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value
NULL into column 'Product', table
'LeasebookSQL.leasebook_user.leases'; column does not allow nulls. INSERT fails. (#515) [Microsoft][ODBC SQL Server Driver][SQL Server] The statement has been terminated. (#3621)
Can anyone please tell me how I can get the form to close without trying to save the record, especially when no changes have been made to the data on the form?
Thanks,
Simon

I have a Access front end connected to a MS SQL database using a ODBC connection which is working fine of course.
When I compile it as a runtime version and install it on the business computer I get an error with the ODBC connection (I can't remember exactly what pops up). On the business computer I have installed SQL Native Client and in the ODBC added a System DSN (which works).

I am in need of consultation for MS Access reading data from ODBC connection. I have SQL Server that has all the data for the project financials etc.
I need a database that will read only certain data from the tables, for example, I don't need to import all 500,000 lines from SQL through ODBC connection, I just want to bring certain data for a list of projects whichever are opened and load only that data in MS Access so the group then can add additional details for that project in a shared MS Access.
Right now, all I can do is connect to that database through ODBC and brings all the data which I don't need all as it increases the size of the database, but just a criteria to specify which data to bring, if that's possible to do.

I am trying to create an ODBC link to a copy of the Northwind data base.I am running Win7 on a 64 bit operating system but am keeping office running as 32 bit for Access, Excel , Visio etc due to the fact that I have a lot of old apps tied to them.
When I attempted initially to create a new system DSN ODBC connection it only allowed me to use SQL drivers. (No plurry good) So after some searching I found out that I could use a file in C:WindowsSysWOW64 called "odbcad32.exe" which has allowed me to view /use the total list of drivers to import data.So I can set up a DNS ODBC named Northwind1 and I can access the database without problems using Excel.However if I try to use the same ODBC link in Access to connect to Northwind1 I get the following error message:"You cannot use ODBC to import from export to, or link an external ?Microsoft Access or ISAM database table to your database".

I have a split database. BE located at a server and FE on each users workstation. There are 8 concurrent users at the most. This runs smoothly over the LAN.
Now I'm adding a new feature to the database. I'm using a wheel loader to weigh products on a weight scale. The operator in the wheel loader is going to use a laptop with wireless LAN to connect to the network.
In risk of loosing the connection which in worst case might corrupt the database, I want to make a new database with a BE/FE setup. The BE will be placed on the same server as the current db. The FE in the wheel loader. I can then link from the current db (BE) to the new db (BE).The new db will only require two linked tables from the current db.
If worst case happens, would my current db be more protected against corruption than if I linked directly to the BE on the current db. I know there's no 'right answer' to this one, but I'd really like some opinions on it though.
Thanks in advance.

I have an Access 2000 split into FE and BE and the client has requested the BE be password protected. I attempt set database password on BE but then when I open FE I get error msg " not a valid password". I get the same error message if FE has same password or if FE has no password.
Any ideas?
Thanks,
