    string strConnString = ConfigurationManager.ConnectionStrings["JobInnConnectionString1"].ConnectionString;
    string s1;
    string s2;
    string path1;
    string path2;
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void SubmitCompany_Click(object sender, EventArgs e)
    {
        if (companylogo.PostedFile.ContentLength > 0)
        {
            s1 = Path.GetFileName(companylogo.FileName);
            path1 = Server.MapPath("Logo") + "/" + s1;
            companylogo.SaveAs(path1);
        }
        if (cover_img_file.PostedFile.ContentLength > 0)
        {
            s2 = Path.GetFileName(cover_img_file.FileName);

        SqlConnection con = new SqlConnection(strConnString);
        con.Open();
        SqlCommand com = new SqlCommand("insertinto_company", con);
        com.CommandType = CommandType.StoredProcedure;
