How do I start with a simple search application


Hi there,

I have a simple database with 3 columns - id, zip codes and salesmen.  I want to create an MVC application that has just one field to enter zip code and a Search button. Once the zip code is typed, I want to search the database and display the name of the salesperson corresponding to the entered zip code.

I read some documentation on Entity Framework and got quite confused. Can someone give me a guideline as how should I proceed. I'm new to MVC. I'm coding this application in c#.

Search filters



I need bit of help/advise on how displaying search filters on my web shop. In my web shop I have different product categories like Skin care , hair care , after shave makeup etc. As each of these product categories can have completely different searchable attributes so if user click on Skin care then only skin care attributes should appear in search filter. I am not sure how to achieve this. One way I can think of is to have separate view for each category and set the filters related to each category separately (hard code) but this will cause problem every time a new product category is added. I want to create it dynamic.

Any suggestions.

Custom Namespaces


Ok, I am having trouble calling a single variable inside the testNamespace.cs file.

string dir = "test";

Right now it is inside the class like so:

namespace testNamespace
    public class testNamespace
        // Test string variable
        public string directory = "test";

        public testNamespace()
            // Nothing


Is there an easy way to do this?

Password field returning empty



I have a website that allows users to register. On the registration form, the user is asked to fill in a password on 2 distinct fields, and upon attempting to post the data, i have requiredFieldValidators for both  textboxes, a regularExpressionValidator to ensure that the user inserts a minimum of 5 and a maximum of 20 alphanumeric characters, and finally a compare validator that makes sure the same password was inserted on both fields.

This generaly works as it should, preventing registrations without inserting a password, but sometimes, for a yet unknown reason, users are able to register without a password being saved nor sent via the confirmation email (the email goes straight to the form to capture the password and not the database).

I was able to contact one of the users that stated he was using a Safari (10.0.3) on MacOS Sierra (10.12.3).

Can someone explain me what is happening? is there an issue with Safari on MacOS that prevents capturing the password fields? I can't test it since i do not own a Mac...

TagLib-Sharp on a website ( (Type 'TagLib.File' is not defined)


(Coding for VB.NET) I am working with the TagLib-Sharp. I really enjoy how it works. Very simple and straight forward. Well, within VS, it is, anyway. I took the files and placed them on my web server, of which included the BIN folder that VS created with the DLL files when I referenced the TagLib-Sharp.dll file. When I run the site through my browser, I get the following error. Type 'TagLib.File' is not defined I was told that I had to create a Namespace for it, so I did that. I also included all the IMPORTS for the different taglib's and that did not work. Here is the code that I am working with. default.aspx <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="TagLib._Default" %>
default.aspx.vb Imports TagLib Imports TagLib.IFD Imports TagLib.IFD.Tags Imports TagLib.Xmp Imports TagLib.Id3v2 Namespace TagLib Partial Class _Default Inherits System.Web.UI.Page Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load Dim mp3 As TagLib.File = TagLib.File.Create("G:\InetPub\wwwroot\Media\m.mp3") Dim strAlbum As String = mp3.Tag.Album Label1.Text = "Album: " + strAlbum mp3.Dispose() End Sub End Class End Namespace I also registered the DLL file with my system. %windir%\\framework\v2.0.50727\regasm G:\WebFiles\taglib-sharp.dll /codebase I also read about this error, where it deals with the .NET version that was used for the file and what the project is made with. I changed the version of .net down to 2.5 and then up to 3.5 and then back to 4.5 and it did not matter. Nothing seemed to work. (Other than a lot of errors when I went down to 2.5, it was a mess) But nothing seems to be working. Any idea's on this would be wonderful. Reading the mp3 metadata is something that I have been wanting to add to an ongoing project for many years. And I am this close, but cannot seem to cross that finish line. Thanks in advance for all assistance on this annoying issue.Carrzkiss [...]
