SQLite: Cannot open network file programmatically, even though worked before

Question

I have used the code below to open a SQLite database file that sits on a network computer for more than a year now almost on a daily basis. Suddenly this morning, I am not able

Answer 1

in version > 1.0.82.0

1. Double the leading two backslashes in the file name (e.g. "\\\\network\share\file.db").

2. Use a mapped drive letter.

3. Use the SQLiteConnection constructor that takes the parseViaFramework boolean argument and pass 'true' for that argument.

See the SQL post here

Answer 2

I had a similar issue. Replacing the UNC (\server\share\folder\file.db) with a mapped drive path (S:\folder\file.db) resolve the issue in my instance.

Answer 3

The error message is very misleading + irritating. Applications working fine in the local environment get failed to start in client server situation.

It has mostly noting to do with the code. Its related to server side.

• Make sure the Write access is available for the server folder containing the file.

• UNC [IP based server path] is not supported still, the network path/folder should be mapped to overcome this issue.

• Some sites+users are saying to mention the Version No. in the connection string. All my applications are working fine without using it.

Connection String:

Data Source=[Mapped Server Location]\[SubFolders]\[FileName].db;

Update:

I tried to prepend \\ to the UNC path and it worked (added additional \\ in the beginning only, not in-between).

Data Source=\\[UNC]\[SubFolders]\[FileName].db;
