Sometimes Google is your best friend

Considering the relative path you are using that link will probably give a hint (found with the Google search above)

OK, just saw that your relative path might be a stripped down absolute path and trying to hide the details.
Checkout the details there. The db has to be there where you expect it.
Note: Single backslash are typically not a good idea in C/C++ and for absolute and relative file path, they are deadly. Use single forward slashes which are also supported by Windows and common on other OS.

I tried with two back slashes and with forward slashes also but both gave me same error
