I need a few options on how I will allow a user to post simple text comments to my website page(s). I will require login to post comments in order to prevent spam posters.
I'm using Visual Web Developer 2010 to design my website. I'm not real familiar with it and do not know if it includes the tool I need to accomplish this task easily.
I'm creating a composite control for a DropDownList (that also includes a Label). The idea being that I can use my control like a dropdown list, but also have it toss a Label onto the page in front of the DDL.
I have this working perfectly for TextBoxes, but am struggling with the DDL because of the Collection (or Datasource) component to populate the DDL.
Basically I want to be able to do something like this:
<ecc:MyDropDownList ID="AnimalType" runat="server" LabelText="this is what will be in the label">
<asp:ListItem Text="dog" Value="dog" />
<asp:ListItem Text="cat" Value="cat" />
</ecc:MyDropDownList>
The problem is, I'm not extending the DropDownList class for my control, so I can't simply work it with that magic. I need some pointers to figure out how I can turn my control (MyDropDownList), which is currently just a System.Web.UI.UserControl, into something that will accept List items within the tag and ideally, I'd like to be able to plug it into a datasource (the same functions that the regular DDL offers).
I tried with no luck just extending the regular DDL, but couldn't get the Label component to fly with it.
I need to add the ability to register users in my web site. I'm sure that 1000's of programmers already did this, so why should I build from scratch? Does someone knows where can I find a module like this as well as other modules?
View 2 RepliesI want to qualify my users ability to use javascript when they enter my website so I can manage any depreciated functionality properly.
I found some code on the web which effectively appends the quesrystring, then runs a javascript redirect. On the second page the querystring is rechecked - if its go &js=1 then they're good, else they're not good. The result is put into session so I can carry it throughout the site.
The problem I have with this is that firstly I have to load the first page twice. However I then need to be able to get the session variable back again, which means this happens on the first page:
round 1 - page loads, checks if javascript has been tested or not. If not run redirect to itself.
round 2 - get querystring value and put into session.
However the page may then go on to load some javascript dependent controls, but session isnt picking up the javascript (probably due to the page life cycle)
I supose I could then go on to test the querystring as well, but it doesnt seem too elegant a solution.
I have an application that I am writing in ASP.NET MVC 2 following the Nerd Dinner tutorial. I am very much a beginner and was looking for examples/tutorials I could follow that would enable me to learn how to code the following scenario:A user has the option to select an option from a dropdown.If the option is not there then they can enter a new option and add it to the database and list in the dropdown.
I would like this to be done without the user leaving the page and what they have entered so far.I am using a simple Entity Framework 4.0 model which I have built a repository on top of so I have methods I can call to save the filled in user information.If the entry already exists in the database then I would like to offer the user the chance to either select that entry or to continue adding the entry they request because it can be a list of names and of course you can have more than one person with the same name.
I am trying to create a comments page for users to review and comment on an article. I have 2 buttons on each comments posted by users; "Like" and "Don't Like". I am stuck with how to track which user voted already for a given comment. I am thinking of two options and would like to know if they are they way to go or is there a better solution.
Option 1: I have created a table in my database with stores, the comment id, the userid of the user who rated it and the value "like" or "don't like". So each time I have to query my table to find out if this user indeed vote for a given comment. The table unfortunately grows exponentially!!
Option 2: I store the commentid, userid, and "like" or "don't like" value in a cookie on the client's machine. I read the cookie and find out if the user has already voted on a comment. This is proving to be VERY quirky with cookie expiration, growing cookie size and also multiple users on the same machine.
In either way, my test case of ~1500 users, and 2 Million comments, this is getting to be HEAVY on both methods. Is there anything better?

View 3 RepliesI'm wondering if there is a way to create an asp.net webpage that will connect a visitors USB device to an application on the windows bases server? This way we avoid having to install a software on the visitors computer to control a USB device update that they purchase form us.
All they have to do is visit our update page, plug their deivce to the USB, and have our site update the usb hardware. Possible? or am I dreaming? :)
i found software like: USB over IP, and few others. But not show ure its possible to create a C# or vb.net based ASP.net page to control the visitors USB device.
I am working on a component in C# to record how many unique viewers have viewed my website / page, making certain the same user revisiting, is not recorded twice. What is an efficient method to write such a component? Do you track cookies or session objects?
Would I record their ip address (which is not static) or computer name?
This information would be stored in a database (as far as I know)
I have to maintain session of two users on a sigle page.And the path is. UserPath:
1.User logins with his credentials((We retrive their credentials from login table) .
2.He invites some of his friends for a birthday party.
3.And send an url link to share some of the gifts with them in which gifts are provided in Share.aspx page.
4.Userlogouts.
Invites path:
1.Invite logs in with his credentials(We retrive their credentials from invites table).
2.He is directed to go to Share.aspx and list the items he require.
3.And he logs out.
Now i have problem in maintaining session for both the user and invite. How can i maintain the session so,that the user can identify a particular invite from the list of invites an his chosen items.
I have a website that has 10 aspx pages in it, and I'm trying to count how many users are on any one page at a time, and display that number on the web page. I have set it up to use an Application object ("TotalViewers"), and initialize it to 0 in the Application_Start event handler of the global.asax file. My reasoning (probably way off base) is to increment the count on each page load, and then decrement the count on each page unload. The increment part works ok, but when I add the code in the page unload event handler to decrement, it seems that Unload happens before the Page is presented to the client, so the value always stays the same (adds one in page load, subtracts one in page unload).
How else can I track number of users on each page? (simply, becuase I am still a beginner). I have already done some google searching and haven't come up with anything useful.
All my pages are being navigated via a TreeView control.
In the web.config file i have put some code in so that when users log in they will be re-directed to another part of the website which only registered users can access. for the admin part only the admin can log in and it takes him to the admin section and that works fine. it is only this that is causing me problems.
the code i inserted for which the user needs to be diverted to is:
<location path ="UserLoggedInFindUs.aspx">
<system.web>
<authorization>
<deny users ="?"/>

I'm researching the feasiblity of building the ability to browse a subversion repository from my web app. I'm developing in asp.net.

View 2 RepliesI'm looking into integrating a Digg-like comment system into a website with an existing user base.I know there are things out there like Disqus and Intense Debate, that are meant for people to add to their blog, but I want (need) something that I can tightly integrate into my site, with out requiring the user to sign on multiple times.
Basically the only things I came across were 3rd party hosted stuff that really doesn't allow for the kind of integration I need.I'd rather not roll my own ajax/moderated/rankable/threaded comment system, but I don't see any good options out there to avoid doing all that work.The site is asp.net, so I'd really like to have something that is meant to integrate with asp.net.

View 1 RepliesI just read the MSDN Magazines article on Dynamic Data and it got me wandering, could I use this in MVC3? Then with a little research the answer is yes, but you have to copy all these assemblies, modify the global.asax file etc. The same if one wanted to use web forms and MVC3. Wouldn't it just be easier to be able to choose a blend option when creating a new application in VS? My suggestion would be if one wanted to create a hybrid application that blended two different application styles, one could just choose multiple apps at the start, such as MVC3 and Dynamic data; and VS would just add or modify the necessary references so one could use the two development styles in a single application.
I realize that some would say this would probably defeat the purpose of the different styles, but if developers are gong to do it anyway, why not be supportive. What did Emerson say? "A foolish consistency is the hobgoblin of little minds".
