Unable to open sqlite database file when program launch at windows startup

Question

I set my program to launch at startup by the below code:

Registry.CurrentUser
    .OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true)
    .SetValue(Application.ProductName, Application.ExecutablePath);

After restarting Windows and login to my account (with admin access), the program runs successfully, but when it tries to connect to the sqlite file, it encounters the following exception:

"ClassName": "System.Data.DataException",
  "Message": "An exception occurred while initializing the database. See the InnerException for details.",
  "Data": null,

This problem disappears when I run the program manually

I tried to use a text file instead of a database, but a file created by a program run by Windows is different from a file created by a program run manually.

How can I solve this problem on windows 10?

Answer 1

When I restart and run in the startup case, the current directory is the systems directory.
So to fix this I need to use the full path.
