My program has to access an SQL Server DB file that is in the same folder as
the executable. i dont want to setup a server. i was able to do this on my
own computer, the program would access any sql server db file without it
being attached to the server. When i take it to another system it fails to
run.
All systems have SQL Server Express and SQL Server 2005 installed.
Can someone please direct me through the steps to fix this problem?
There are 2 errors (on different pcs) i get when i try to access the db one
is:
Error 1
Generating user instances in SQL Server is disabled. Use sp_configure 'user
instances enabled' to generate user instances.

If you are using a provider (Internet) you will have to get the
provider to make the settings recommended in the second message.
If you are on a local network you will need to get the Network staff
to make the settings for you.

Do you mind explaining to me how the connection string written their works?
because i read through it and then tried to use that connection string (of
course with my own db name) but the string is not a valid C# string, i mean
|DataDirectory| as its mentioned in the description is a keyword but its just
hanging there outside the qoutes and of course it didnt compile as it was, i
tried some other combinations, they didnt work either, so can u please either
tell me the correct connection string, or give me an example?

I'm not sure where your problem is, but here are a couple pointers..
The string you are referring to should be a valid C# string..
"|DataDirectory |" should be replaced with your local database
directory.
The @ character proceeding the string means the string should be taken
literally.
The following string:
@"Data Source='.\SQLEx press'; Initial Catalog=; Integrated
Security=true; AttachDBFileNam e='" + |DataDirectory| + @"\MyDb.mdf' ";
is equivalent to:
""Data Source='.\SQLEx press'; Initial Catalog=; Integrated
Security=true; AttachDBFileNam e='"" + |DataDirectory| + ""\MyDb.mdf '"";

Hi,
I like to build a small simple dinamic website: Point-of-sale

invoices and download the logs to be imported into Excel.
I once could write a bit in ASP/SQL/HTML/JAVASCRIPT and even some
Excel-VBA but have lost most knowledge about that and I never know a
lot nor did I know how to set up a simulating PC to write and test the

Is it at all possible to access a sql database, whether reading it or storing values to it, without having sql server installed or running as a process in the background? Perhaps this can be done using SMO?
I ask this question because my client does not want my application to install any sql rdbms (sql server, mysql, db2 etc.) on their machine. So is there a way to process data directly to a database file such as a Sql Server .mdf file?
