View 2 Repliesas a php developer ive been told to go the MVC route which ive been trying since yesterday. Im using visual web delveloper 2010 express and im using the MVC template project.Ive basically got a news table in MSSQL Express, in there are these fields ID,(Title,Body,PostedOn,PostedBy) all i wanna do is loop through them to put them on the view.Im after a nudge in the right direction, I want to be able to do a SQL lookup in the controller put that data in a DataTable then run a foreach loop on the table to display this on the view. The problem im getting is I know youre not suppsed to put any HTML in the controller and I cant pass the datatable to the view to do the loop in the view.. so where/how do I do the loop.

Also, maybe I should be going about this another way as I wanted to add a drop down to each record and a link to each record.On pointers on how I should do this would be great too.
'DataTable' is an ambiguous reference between 'System.Data.DataTable' and 'Microsoft.Office.Interop.Word.DataTable'

Currently I am working on a project at work that deals with MVC. I have never used MVC before, only dealt a little with ASP with VB, and that's it. I've dabbled in HTML but not much. I don't currently have the money for a book, so I'm using this forum. So there's a lot of jargon I may not pick up on or may ask a lot of questions, so please bare with me.Anyways here's what I would like to do, or understand. We're using ASP.NET Membership Security (not sure if that's what it's actually called) for passwords and accounts. My issue is that I've been working on other projects while the rest of my team has been working on this, so they know more about it than I do. And I don't want to take too long to understand it, but I have to find the best way to make sure the following doesn't happen:
1) When changing a password, it can't be within the last 10 passwords used for that user.2) When creating/changing a password, it cannot have dictionary words, names, phone numbers or personal data within it.3) The password must be a minimum of 16 characters.Number 3 is rather easy and completed I believe. However, 1 and 2 prove tenuous. We want to store the previous passwords hashed and we were going to save the salt used. However, I'm beginning to think that with the Membership class you can't specify the salt to hash a password. Is there a way to de-hash a password? We do not want to store the passwords as plaintext, so that is out of the question.I believe the best order (for 1 and 2) is to do 2 first (before it's hashed) and then 1. For two, I need to know how to call a function in the Model code from a <submit> tag in the View code. I've done a little research online but thought I'd ask and see if it gets answered while I'm looking for the answer.
In general, my questions are:1) How do I call a function in the ****Model.cs from a <submit> tag in the *******.aspx?2) What's the best way to compare previous passwords that are hashed? 3) If I know the salt, can I de-hash a password? (I believe the answer to this is no.)4) Can I specify the salt to hash a password? (I believe the answer to this is no.)5) If #3 and #4 are no, then should I do encryption instead of hashing?Details: MVC2, C#, Membership.
