Publish Project and include access database file RRS feed

  • Question

  • Hi all,

    i am new to visual studio 2017 and visual basic development.

    I am developing a simple app with an access database connected to.

    When i compile the app i find into the output folder the db and the executable file can correctly interact with it.

    The problem comes when i publish it and the setup.exe file is created, at the moment i run it apparently the software installs correctly but when it tries to run the app i get an error like the db was not fount at a pretty weird path i never defined.... here an example:


    Any hint?

    Best regards

  • To get the path try





    Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Data","XXXXXX.accdb")

    If you have |DataDirectory| in your connection string in app.config the path would resolve itself if using TableAdapters

  • This cryptic path is where clickonce deploys the app to. Each time you publish it will be different.

    Did you figure this out?

    If not, did you add the database file to your project and set the 'copy to output directory' property to 'copy always' or 'copy if newer'
    If you did then when the application is installed it will get copied to your 'weird path \data' directory. The path to it will be, like Karen said:

    Dim PathToDB As String
    PathToDB = "|DataDirectory|\MyDatabase.accdb"
    con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & PathToDB & "';Jet OLEDB:Database Password='" & pSwRD & "';Mode=Share Deny None"
