RE:forgot password adding space

Hello.

We recommend you to copy/paste password via some plain text editor, e.g. Notepad. This extra space is not added by Kentico, it is added when you copy password form your e-mail client. Anyway, it is not added every time, sometimes you are able to copy password string only. In any case, copy it through some plain text editor helps always. If you want check inputted string for empty space and if so, trim it, you can customize Logon form web part (\CMSWebParts\Membership\Logon\LogonForm.ascx), Login1_LoggedIn method.

RE:forgot password adding space

Hi
i checked this method Login1_LoggedIn and isnt hit if password incorrect, so couldn't find where to trim password.

only hits Login1_LoggingIn.

I retrieved password field by:
TextBox txt = (TextBox)Login1.FindControl("Password");

but not sure how to proceed.
Please advise.


  void Login1_LoggedIn(object sender, EventArgs e)
    {
       
        // Ensure response cookie
        CookieHelper.EnsureResponseCookie(FormsAuthentication.FormsCookieName);

        // Set cookie expiration
        if (Login1.RememberMeSet)
        {
            CookieHelper.ChangeCookieExpiration(FormsAuthentication.FormsCookieName, DateTime.Now.AddYears(1), false);
        }
        else
        {
            // Extend the expiration of the authentication cookie if required
            if (!UserInfoProvider.UseSessionCookies && (HttpContext.Current != null) && (HttpContext.Current.Session != null))
            {
                CookieHelper.ChangeCookieExpiration(FormsAuthentication.FormsCookieName, DateTime.Now.AddMinutes(Session.Timeout), false);
            }
        }

        // Redirect user to the return url, or if is not defined redirect to the default target url
        if (ValidationHelper.GetString(Request.QueryString["ReturnURL"], "") != "")
        {
            UrlHelper.Redirect(ResolveUrl(ValidationHelper.GetString(Request.QueryString["ReturnURL"], "")));
        }
        else
        {
            if (this.DefaultTargetUrl != "")
            {
                UrlHelper.Redirect(ResolveUrl(this.DefaultTargetUrl));
            }
            else
            {
                UrlHelper.Redirect(URLRewriter.CurrentURL);
            }
        }
    }

    
    /// <summary>
    /// Ligging in handler
    /// </summary>
    void Login1_LoggingIn(object sender, LoginCancelEventArgs e)
    {
        TextBox txt = (TextBox)Login1.FindControl("Password");
        // Ban IP addresses which are blocked for login
        if (!BannedIPInfoProvider.IsAllowed(CMSContext.CurrentSiteName, BanControlEnum.Login))
        {
            e.Cancel = true;

            LocalizedLiteral failureLit = Login1.FindControl("FailureText") as LocalizedLiteral;
            if (failureLit != null)
            {
                failureLit.Visible = true;
                failureLit.Text = ResHelper.GetString("banip.ipisbannedlogin");
            }                        
        }

        if (((CheckBox)Login1.FindControl("chkRememberMe")).Checked)
        {
            Login1.RememberMeSet = true;
        }
        else
        {
            Login1.RememberMeSet = false;
        }
    }

Thanks

RE:forgot password adding space

Hello.

Please find code example below. You can place it within a Login1_LoggingIn method. If password contains any empty character, user will be notified about it and logon process will break for that moment.

If you would like to remove any empty character automatically in Logon form, you would need a full source code for that. If you have, please let me know and I will provide a solution for you.

Code example:

bool bContainsWhiteSpace = false;
        string sPassword = Login1.Password;

        if (sPassword != null)
        {
            for (int i = 0; i < sPassword.Length; i++)
             {
               if (char.IsWhiteSpace(sPassword))
               {
                 bContainsWhiteSpace = true;                  
               }

               else 
               {
                bContainsWhiteSpace = false; 
               }
             }
        }

        if (bContainsWhiteSpace)
        {
          Response.Write("Please remove empty space from password.");
          e.Cancel = true;
        }
