Dispose your sql connection, and prob your adapter as well

<configuration>
<connectionStrings>
<add name="ETCDatabase" connectionString='Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename="D:\Users\James\Downloads\ETCWinFormsApp\ETCDatabase.mdf";Integrated Security=True'
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

connection string I assume to be fine

Someone shared the program to me and do I have to change the SQL connection string accordingly to run the program?

Does the path to that file / the file exist?

Oh yea I have the file and the path to it

I was looking for it

do i have to change the file path?

if the file path is the same as your config, then no

ok i have just fixed the database file path

now it shows another problem

Now your connection string is borked

I changed my sql connection string from this

To this:

<configuration>
<connectionStrings>
<add name="ETCDatabase" connectionString='Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename="D:\IOOP\ETCWinFormsApp_20230219\ETCWinFormsApp\ETCDatabase.mdf"Integrated Security=True'
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

===================

"D:\IOOP\ETCWinFormsApp_20230219\ETCWinFormsApp\ETCDatabase.mdf"

this is the path to the file i copied from file explorer

Youre missing a semicolon

ohh god

hang on
