    Function FileExists(sPath as String) As Boolean
        Dim svcSFA As Object
        Set svcSFA = CreateUnoService("com.sun.star.ucb.SimpleFileAccess")
        Dim bExists As Boolean : bExists = svcSFA.exists(sPath)
        Dim bIsFolder As Boolean : bIsFolder = svcSFA.IsFolder(sPath)
        FileExists = bExists And Not bIsFolder
    End Function ' FileExists

UNO services have an extensive online documentation in the api.libreoffice.org website. Visit the SimpleFileAccess Service reference page to learn more about the methods provided by the service used in the example above.

    res = com.sun.star.ui.dialogs.ExecutableDialogResults
    filepicker = CreateUnoService("com.sun.star.ui.dialogs.FilePicker")
    filepicker.Title = title
    If res.OK = filepicker.execute() Then
