Lock A Record When Two Members Are Trying To Access It?

Jul 5, 2010

I have the scenario like this,

My environment is .Net2.0, VS 2008, Web Application

I need to lock a record when two members are trying to access at the same time.

We can do it in two ways,

By Front end (putting the sessionID and record unique number in the dictionary and keeping it as a static or application variable), we will release when the response is go out of that page, client is not connected, after the post button is clicked and session is out. By backend (record locking in the DB itself - need to study - my team member is looking ).

Is there any others to ways to do and do I need to look at other ways in each and every steps?

Security :: Filtering Members List / Only Members Whose Name Contains The Typed Characters Will Show Up In The Gridview?

Apr 28, 2010

Our site has a page for maintenance of existing members (e.g. adding / changing roles, etc.)This page currently uses a gridview to show a complete list of all members, based on GetMembers() method to populate it.However, as the number of users has grown to several hundred, it has become difficult to locate a particular user by paging through several pages.Is there a way to narrow down this list, maybe with a filtering textbox, so that as you start typing into that textbox, only members whose name contains the typed characters will show up in the gridview?

Web Forms :: Access Members Control On MasterPage?

Dec 17, 2010

The website will have public and private (members) access.I'm using VB and MS access database. Registering, login, MasterPage (Master1), default.aspx and users (members.aspx) pages are already set up. What I wanted or what I'm thinking to do is to also base the members.aspx on the MasterPage.

When a user logged in, I wanted to add additional menu (reserved only to members) to the MasterPage and
remove/hide unnecessary menu. Here is a scheme of what I want:

MasterPage + default.aspx: (visible to the public)
Menu1
Menu11, Menu12, Menu13
Menu2
Menu21, Menu22, Menu23
MasterPage + members.aspx: (When user login)
Menu1
Menu11, Menu12, Menu13
Menu3
Menu31, Menu32, Menu33

If the user logout, it will return to MasterPage + default.aspx. Nowing that if the user authentication successful, he will redirected to members.aspx,

1. how can I, when loading members.aspx, manage the MasterPage so that I can show and hide some of its menu? how to use members controls on the MasterPage?

2. in case I'm wrong with what I'm trying to to do, what is your advice?

3. FYI, I'm using VB. Any code in C# will also be OK. I will just have to convert it.

4. I might probably use placeHolder to show and hide these menu in the Page_load event of members.aspx (refer to what I don't want in 3).

Security :: Lost Access To Control Members And Roles?

Aug 8, 2010

I am working on an application that resides on a development server on our internal network. The application was originally written to use Membership and Roles. We got busy almost a year ago before the app was finished, and now we are trying to get it ready to use internally.

The login page works just fine, but I have lost the ability to controls users and roles. I am running Visual Studio 2010 Professional now on a Windows 7 VM. I can open the application fine but there is no Web Administration Tool available for me to manage users or roles. If I go to Website -> in Visual Studio, there is no option for ASP.NET Configuration in the drop down menu. It simply isn't there.

How can I regain access to manage users and roles for this application? We are using Forms authentication and the database resides on a SQL Server 2005 instance on a separate box from the web server and my local VM.

Access The Current Record In An Asp:Repeater?

Nov 9, 2010

Suppose I have an asp:Repeater that I am using to display a list of names and phone numbers.

<asp:Repeater runat="server">
<ItemTemplate>
<p><%# Eval("name") %></p>
<p><%# Eval("phoneNumber") %></p>
</ItemTemplate>
</asp:Repeater>

Now, let's make it more fun. Let's suppose that there is one or more phone number per name. I feel like I could use a repeater within a repeater to repeat the phone numbers. I could also use a for loop in my asp code. However, the Eval function is the only way I know of to access the current record at runtime and Eval only returns a string and only runs in <%# Eval("X") %>. How can I get the list of phone numbers that is a member of the current record?

Access :: How To View Single Record Details

Sep 7, 2010

Over the last couple of weeks, i've been playing around with expression web to try and update our current company website: [URL]

Basically, our site is quite simple. We have individual product categories that are displayed and then the user can click through to view the individual product specification and pictures of said product.

I've created the category pages and inserted hyperlink fields to link to the individual product pages which works fine.

The problem i'm having is getting the specification and pictures to display on the product pages.

I'm literally tearing my hair out as i'm quite new to this.

The access database i'm using has the following fields, ProductID, CategoryID, Description, Comments (This is the Specification field) and then Image1, Image2, Image3 etc all the way up to image 10.

What i've been trying to do is to use an imagefield within a gridview to pull the Image name from the image fields and then display said images from the images folder. I have got this to work of a fashion, yet all the images are displaying instead of the particular product images only. I believe i need to add a query string to do this yet i'm totally at a loss as to how to set this up...

I'm also having the same problem with the specification (comments field) as i can't figure out how to only display the individual product spec..

Access :: Get The Primarykey Of A Newly Inserted Record?

Aug 18, 2010

I thought this would be easy before I started, but I should've known better.

I just need to get the value of primarykey from the newly inserted record so I can pass it in the query string to the next page the user will be directed to.

Here's my code:

VB Code-Behind:

I had found what looked like a good soultion yesterday by the moderator "ecbruck" at this post:

And unfortunately I don't have time to teach myself a new database platfrom and am stuck with MS Access for the moment...teaching myself asp.net has my head spining enough as it is.

Access :: Get The ID Of The Record Just Entered Using AccessDataSource & FormView?

Mar 17, 2010

I'm using an access database that has an AutoNumber field as the primary key. After adding a record I'd like to retrieve the ID for the record that was just entered, however, I'm not able to figure out how to do this in ASP.NET using standard AccesDataSource and FormView functionality. My goal is to retrieve the ID so that I can then use it to add an additional record in a child / sub table.

I could do it strictly using vb.net and forget about using the InsertCommand for the AccessDataSource and it's built in functionality. However, that would require a complete rewrite of some other items, accomplish this using the standard AccesDataSource functionality.

Below is a sample of something I've tried to do using "Direction='Output'" on one of the ID field for one of Insert paramaters (source: http://www.4guysfromrolla.com/articles/050207-1.aspx). The plan was to then caputre that "output" using the my "_OnInserted" sub procedue. However, apparantly I'm not able to use this with AccessDataSource. Did some research and saw that I'd have to switch to SqlDataSource which I'd rather not do cause all other pages use AccessDataSource and I'm having problems defining my connection string with it.

Html:

<html>
<body>
<form runat="server" id="Form1" method="post" encType="multipart/form-data">
<asp:FormView runat="server"
id="FormView1"
DataSourceID="DataSourceFormView1"

Context Of An Asp.net Website - Way To Check Whether User Has Access To A Particular Record

May 26, 2010

I have a webpage that you pass in an id parameter (via a querystring), which it then uses to fetch data from a database. Typically, a user would navigate to this page from another page that lists only those records that the user has access to. However, if they go directly to the page by typing in the URL in the Address Bar, they can effectively view any record they like. to type something like http://localhost/TestSite/ClientAdmin/ManageLocation.aspx?LocationID=5 into their Address Bar, they can access the database record with the LocationID equal to five - even though they shouldn't have access to it
