How do I specify the flow direction of text?


I have created a website where trusted users are able to translate the text on the web pages.  But, I am having trouble with changing between “Left to Right” and “Right to Left” of translated text on each web page for a specific language.  I understand that there is a FlowDirection="LeftToRight" command.  But, I do not understand how to specify the direction in the code segment of each web page, depending upon what is specified in the database.  Can anyone help me please?

asp roles not working



I'm using vs2010 I'm having an issue, I have created an event for the login clicked on the login.  I'm trying to use if (user.isinrole("Sales")) Response.Redirect to a specific folder with a default page that I've created.  Although even trying to redirect to the about page doesn't work either.  If I type the page address in manually to the URL it works, however if I deny another role member in the web.config file it doesn't seem to deny them either.  What could I be doing wrong?

ASP.NET core class libraries vs desktop winforms class libraries ?


Suppose i made a new ASP.NET core MVC app targeting the "full" .net 4.6.1 framework. i then added a few .net 4.6.1 class libraries to the solution for various purposes (service layer ,business layer ,data access layer ,utility .. etc). 

the question : can i grap those .net 4.6.1 class libraries and use them to make desktop winforms app with similar functionality ?

The same question with different wording : does developing for ASP.NET core vs winforms (assuming both targeting 4.6.1) differ only in the presentation layer with no differences in other layers ?

ASP.NET MVC View dynamically changes according to dropdownlist selection



I am new to MVC 5 and I have a scenario that requires me to develop a registration form that changes according to the selected dropdownlist value. For example, if i select Admin from the dropdownlist, the view will display 3 fields for registration such as username, password and email. Subsequently, if i select "Normal User" from the dropdownlist, the view will change to display 5 fields for registration such as username, password, email, age and address. After filling up the fields, I can then press the submit button and save the data to the corresponding table accordingly.

I've tried implementing this by having 3

classes for each user roles. And having Javascript to hide and show the
classes acccoridng to the dropdownlist changes. However, it does not work. Is there any great way to implement this?

Any comments and feedbacks are much appreciated!

URL Creation


How do you create a url form a cshtml page that will be  filled out and submitted.

The form data will be saved to a database with a column that is a  composite primary key  (Formname + Guid) and a column that will hold a URL is saved which when clicked points to this form with data  outside of mvc.  How can this be done?

How to send an authenticated E-Mail?



I want to send authenticated emails from within my web application to prevent them to be delivered into the recipient's "Junk" folders.

I tried this code:

        private static void send_authenticated(MailMessage msg)
                SmtpClient cli = new SmtpClient(cfg_Server);

                cli.DeliveryMethod = SmtpDeliveryMethod.Network;
                cli.EnableSsl = false;
                cli.UseDefaultCredentials = false;
                cli.Credentials = new NetworkCredential("myUser", ""); 
                txt_Status = "OK";
            catch (SmtpException exc)
                txt_Status = exc.Message;
                txt_Status += "\n" + exc.Source + "\n" + exc.StackTrace;
            catch (Exception exc)
                txt_Status = exc.Message;

There is a username "myUser" and an empty password. The username is the name of a group mail address, which has no password.

Well, the email arrives at the recipient. Then, I changed "myUser" to something that doesn't exist, and the mail also arrives.

Because of this behavior, I believe that there is no authentication at all?

What am I doing wrong?


How ASP.Net MVC support separation of concerns


in webform aspx page was tightly couple with code behind file. so the person who is working with aspx file he has to write code in code behind.

the same way mvc provide controller, view and model. but think when model is not created then how a developer will create controller which refer that model class and same model is also refer in view too. in mvc by theory there is no dependency between controller, view and model but practically when some one will start work then they found there is dependency between between controller, view and model because person A can not complete his controller code if model is not prepared and same way person B can not complete view if model is not prepared because we refer model in view too and as well as we use various model property name in view to show suppose employee data.

so anyone can tell me what MS try to say separation of concerns in MVC ? please explain with easy example and also compare the same with web form .


Gridview - C# - asp page (with master) - Grid remains on Screen AFTER select


Hello, I have an issue that I need your help with please. I have a ASP page (C#) with a Gridview pulling data from SQL Server (code below).

When I select 1 of the results, gridview remains on screen, but only the one record selected.). I dont want that. What can I do to tell the gridview that after select, go away... <%-- ReSharper disable Asp.Image --%>
<%-- ReSharper restore Asp.Image --%> [...]

webRTC with signalR on browsers live chat


Is it possible to use signalR on top of webRTC in order that non webRTC supported browsers will get only video data with no sound.

They will not be able to broadcast but only receive video data through signalR websocket and use the html5 canvas to show it.

So basically i need 1 regular webRTC upload streaming that signalR server Splits into 2 kind of streaming broadcasting one regular webRTC and one video data through websocket for use in the html5 canvas to show it.

Dose signalR can give me that solution?
