View 5 RepliesI need to create something which is like an Add friend function in my website which works like this:
1) User types in name of the person he wants to search in the search field and clicks enter
2) on the same page, the search result will come out with an "add friend" button beside every name
3) when the user clicks the "add friend" button, he will be brought to another page (or pop up with a message box?) with a text message field to send to the friend, and a submit button to submit the friend request.
4) over at the Friend's page, he will be able to view the add friend request and decide whether to accept or deny the friend request.

View 6 RepliesI have been trying for a long time to create regEx function that would retrieve inner html of div but still no luck. What I want to do is to retrieve inner html of div with specific class.
Suppose the input is
<body>
.....
<div class="Product"><div class="id">1</div><span>xyz - 1090<br>New Product</span><div>
<div class="Product"><div>2</div><div>
<div class="Product"><div>1</div><br><p>322</p><div>
...
</body>
As you can see inner html itself can contain div tag and have no fixed structure (though will have correct html structure - opening and closing tag). So, how to get the inner html of div with class "Product".

I'm working on an MVC application and I ran into a little snag.
I've got a form with the usual textboxes and dropdowns. I decided to use jquery ajax (GET) to load the dropdowns on load (State Names & Salutations).
No matter what I try, for example:
Code:
<AcceptVerbs(HttpVerbs.Get)> _
Public Function ReturnSalutationDropdown() As ActionResult
Dim dropdown As New DropDownList With {.TabIndex = 1, .DataTextField = "Value", _
.DataValueField = "Key", .ID = "ddl_coSalutation"}
dropdown.DataTextField = "Value"
dropdown.DataValueField = "key"
dropdown.DataSource = AppEnumerations.BindToEnum(GetType(AppEnumerations.Salutation))
dropdown.DataBind()
Dim sb As New StringBuilder
Dim tw As New IO.StringWriter(sb)
Dim hw As New HtmlTextWriter(tw)
dropdown.RenderControl(hw)
Return Content(sb.ToString)
End Function
The ID of the dropdown ends up like: ctl00$MainContent$ddl_coSalutation
It doesn't matter if I use a stringbuilder and a loop to create a <select> with <option>'s, the ID always ends up like above.

I want to create a function that a web method will call - and that function will be in a DLL.
I am assuming that having that function in a DLL is better then leaving it as source since it won't recompile when IIS recycles or whatever schedule that falls under.
Do I need to make this function in a different project (solution) and compile it down to a DLL and then refer to that folder location in the WEB.CONFIG?
And I assume I just put it in the BIN folder in INETPUB - right? Do I need a WEB.CONFIG reference to it as well - in production?

VWD 2008 Express. Visual Basic. SQL Server 2005. I am trying to create a scalar function in SQL Server 2005 wherein I pass a string that respesents a portion of a WHERE clause in the function's SQL statement. I would be passing things like "GDate>1/1/2010 and GDate,1/1/2011" or "Year(GDate)=2010" When I try to build the function it errors out saying basically that the @WhereClause is not a boolean expression. Does anyyone know how I could accomplish this? The part it does not like is in red.

I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false.
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' />
Then in the page I add a HandleNullableBool() function inside the ASPX page.
protected static bool HandleNullableBool(object value)
{
return (value == null) ? false : (bool)value;
}
This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page?
<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />

I'm comfortable sending emails to individuals in ASP.NET, but recently have needed to create a function to send an email to all users in a particular role.
A couple of problems I'm having are:
My shared hosting allows 200 emails per hour. Although not an issue at the moment it could be very soon, so how can I 'throttle' my application to not send out more emails then I'm allowed to?
If want to loop through the emails and send the messages in the background of my app. Rather than have a situation where logging off or closing the browser stops the process. point me in the direction of some articles about this type of thing, my searching so far hasn't given me great results.
I am beginner of asp.net and c#
Currently i am learning on create a website with appointment feature. The website i am doing basically a dental appointment web, which show the free slot of dentist on the website and enable patient to book appointment by schedule an appointment based on time and date given. I have done others thing such as register, login, report those however i have no idea on doing the appointment module. I am trying to learn easy way to create booking feature for dental website. Is that a tutorial on learning to do this or others way which i can easily learn it.
I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.
