Dear all,

I used adodc to navigate through a database but when I close the program , the lock file which is created at the time of opening database won't be deleted and it would remain as the connection to database isn't closed. I tested different codes to close the database but it wasn't successful such as adodc1.recordset.close.

Thank you,
Azadeh

Would be good to get code for opening your db. Something is different to normal. I never got that problem.

You can unload adodc1 object and set to nothing, who about that?

When accessing and navigating a DB the best option is via code only. My suggestion is this:

1.- Connect to your DB as you normally do with ADODC.
2.- Copy the connectionstring generated
3.- Set project-references-MS ActiveX data objects 2.0 ( minimum )
4.- Set the instances in general declarations:

dim cn as adodb.connection
dim rs as adodb.recordset

5.- Use 'em:

set cn=new adodb.connection

cn.open [ connection string generated on ADODC, sorrounded in double quotes ]

set rs=new adodb.recordset

rs.open [ desired query, such as " select * from books" ],cn

6.- Set bound controls:

Set text1.datasource=rs
text1.datafield="YearPublished"


7.- Destroy instances when not in use:
set cn=nothing
set rs=nothing

8.- enjoy the no-more-problems-with-objects DB connection....


Hope this can be useful.....

Hi..

I see the code above and I would like to add a single piece of code...
In any connection you have a option of close
like

Dim con as new ADODB.connection
con.open

similarly we have
' The line below closes the connection explicility and right way to do

con.close

'Than set to Nothing if you want to free resources
set con=nothing
