After publishing application error occurs in finding path to database and xml files

I have OS XP Russian version, after installing programm shows errors "path in russian can not be read" - explaining in my way. Does anybody have any idea? Thanks

    public string getDBpath() {
                string path1 = System.Windows.Forms.Application.StartupPath;
                string path2 = "safer.sdf";
                string path3 = Path.Combine(path1, path2);
                return path3;

            }

            public string getXmlPath() {
                string path1 = System.Windows.Forms.Application.StartupPath;
                string path2 =  @"data/fp.xml";
                string path3 = Path.Combine(path1, path2);
                return path3;
            }

            public string getXmlPathTxt() {
                string path1 = System.Windows.Forms.Application.StartupPath;
                开发者_Python百科string path2 = @"data/xml_data.txt";
                string path3 = Path.Combine(path1, path2);
                return path3;
            }

Not sure if this would solve the problem but you could try changing the System.Windows.Forms.Application.StartupPath to Assembly.GetExecutingAssembly().Location, and see if that fixes it.

public string getDBpath() {
            string path1 = Assembly.GetExecutingAssembly().Location;
            string path2 = "safer.sdf";
            string path3 = Path.Combine(path1, path2);
            return path3;

        }

        public string getXmlPath() {
            string path1 = Assembly.GetExecutingAssembly().Location;
            string path2 =  @"data/fp.xml";
            string path3 = Path.Combine(path1, path2);
            return path3;
        }

        public string getXmlPathTxt() {
            string path1 = Assembly.GetExecutingAssembly().Location;
            string path2 = @"data/xml_data.txt";
            string path3 = Path.Combine(path1, path2);
            return path3;
        }

You can try to use Thread.GetDomain().BaseDirectory instead of System.Windows.Forms.Application.StartupPath.

If this is not working I would advice you to attach to the deployed version of your application. Therefor you can easily add Debugger.Launch(); right befor your pathes are created.
