It highlights this bit of code:

I'm trying to program a site so object oriented as I am able to....To do this I found a Paging example on the net.....but written in VB - and I'm programming in C#.In the VB example there is a line:
[Code]....
I have googled this a while now - and what I can figure out is there is missing something.....But I cann't figure out what.
I created a control where other developers can create an instance and use. There is a button click in the control. How do I allow developers to plug in their own code in a certain part of my control? I am not sure if or how exactly to use a delegate or event in this scenario.
[code].....
How to I update MyControl to allow this?
I have created a custom composite control basically with two checkboxes. I have created a subscribable event, and the consumer has subscribes to it. But when I go to excute it, the delegate reference is null. What am I missing and why is it losing its subscribed events?
[Code]....
I am using VS2008 SP1 targeting .Net 2/3.5SP1 web site.
I have a control that handles commenting. In this control, I have set a delegate event handler for sending an email.
I then have various types of controls, e.g. blog, articles etc, each of which may or may not have the commenting control added (which is done dynamically with me not knowing the id's), i.e. the commenting control is added outside this control. Each of these controls handles it's emailing differently(hence the event).
What I'm trying to determine, is how to assign the event in the parent control. At the moment, I'm having to recursively search through all the controls on the page until I find the comment control, and set it that way. Example below explains:
COMMENTING CONTROL
public delegate void Commenting_OnSendEmail();
public partial class Commenting : UserControl
{
public Commenting_OnSendEmail OnComment_SendEmail();
private void Page_Load(object sender, EventArgs e)
{
if(OnComment_SendEmail != null)
{
OnComment_SendEmail();
}
}
}
PARENT CONTROL
public partial class Blog : UserControl
{
private void Page_Load(object sender, EventArgs e)
{
Commenting comControl = (Commenting)this.FindControl<Commenting>(this);
if(comControl != null)
{
comCtrol.OnComment_SendEmail += new Commenting_OnSendMail(Blog_Comment_OnSendEmail);
}
}
}
EDIT:
The reason I ask is that if I search from this.Page as the initial control, I am worried about time taken to search down the control tree to find it. Each different type of page would be different in how many control it would have. On some testing, it returns back quite quickly the result.
The issue is two fold in my ASP.NET Web Application. I need to use a custom Distinct() via LINQ to SQL, and then assign thevar as a DataSource to a GridView.
If I use the custom Distinct that implements IEqualityComparer,I get "Unsupported overload used for query operator 'Distinct'" exception. but if i somehow get past this, i get "The data source does not support server-side data paging" exception on GridView.DataBind(). here is the code:
[Code]....
And here is the IEqualityComparer:
[Code]....
With this code I get Unsupported overload used for query operator 'Distinct'. BUT! if I change the code to
[Code]....
, I get System.NotSupportedException: The data source does not support server-side data paging
I have a php function, preg match which i need to convert into c#..It has a regular expression
"/\s+/"....
Its supposed to match the whole string including newline..and in PHP i am getting the whole string...I want to get the result of the whole string match in C#...i have used Regex.match method...But it returns me a blank array..Suppose the string = "title"....Why am i not getting the correct match..?
I have a string of information that I need to parse. I've written a regular expression to find the information I need. Now how would I iterate through each regex match and add it to a list (or do something to it)?
View 2 RepliesI am not that good in SQL syntax and need some help. I am trying to create some search functionality for my website. Basically it just has to search for product names. Now I have a simple statement like SELECT * FROM Products WHERE ProductName LIKE '%' + @ProdName + '%' This statement does not fit to my requirements.I have 2 issues:
1. Assuming someone searches for "blocks". The result that I get is product names with the word "blocks" in it, however I would also like to display results with product names the have the word "block" in it i.e without the "s" In short I want to match the possible product names from the keyword e.g block, blocks, blocking etc I dont want it to search the exact name but may be just partially. If the keyword contains the exact word from the product name, well and good but it should also display the products where the keyword is partially matching.
2. Assuming someone searches for the words "concrete blocks". I get the result with products that have the words "concrete blocks" only. But I would also like to get the result with say "Louvre Blocks" in the total results displayed.So can someone kindly help me sort out my issues. Sorry if im repeating words but im just trying to make an understandable point.
I am looking for a regular expression that matches R33 and r34E for example.I used (R|r)[0-9]{2}+[A-Z]{1} but I got an error in ASP.NET .

I am trying to translate or convert C# code that a friend gave me. I have limited C# knowledge but was going along OK until I hit the following code that includes a delegate. I cannot figure out how to get the equivalent functionality in VB.NET. I'm using
.NET 2.0 and VS2005.

I have a table being brought in using HttpWebRequest (screen scraping). The table I grab is formatting properly but I have noticed a situation. This table has a URL which refers to a physical web page. What I would like to do is to take that URL using a .Replace clause and thereby change the URL to reflect <a href="details.aspx?id=111"> as opposed to <a href="111.htm">. So I went ahead and tried doing it this way but it doesn't do any replacement.

I figured using the regex expression it would find it and then I could just reuse it.
I have a list of strings:
var listOfStrings = new List<string>{"Cars", "Trucks", "Boats"};
and I have a vehicles options which has a Name field.I want to find the vehicles where the name matches one of the items in the listOfStrings.I'm trying to do this with linq but can't seem to finish it at the moment.
var matchingVehicles = Vehicles.Where(v => v.Name == one of the listOfStringItem)
I use the class below in my code-behind to connect to my database. How would I (overload?) this class to choose between multiple connection strings (databases)?
Or should I have a separate class for each connection?

In a asp.net mvc form, im using a radiobutton set, to set a property.
<%=Html.RadioButton("Tipo", "Pizza",
CType(Model.Tipo = "Pizza", Boolean), New With {.id = "Pizza"})%>
<label for="Pizza">Tipo Pizza</label>
<%=Html.RadioButton("Tipo", "Barra",
CType(Model.Tipo = "Barra", Boolean), New With {.id = "Barra"})%>
<label for="Barra">Tipo Barra</label>
I need the CType or i get an overload error. This case seems like the most commom use of radiobutton when working with a Model property. Of course i could create a partial view or a control, but apart from that, is there a cleaner code to accomplish this?
I am working with .net 3.5 and making application in asp.net. I show some application which is make in C# in Windows form where i see following code in class level declaration

and following code in form load

and following code in some event

Now my problem is I am making application in asp.net code behind VB.net where I cannot how to apply all this in my application. I more confuse with Delegate and BeginInvoke. I read somewhere that to use BeginInvoke in VB you should use Ajax.
I have a dummy html file:

I need to add a autoincrement int after the http://www.google.com, though unique for each occurance so the result will be:

<p><a href="http://www.google.com" 1>link 1</a></p>

Obviously with .replace I get [URL] 3 2 1 > 1 and so on... I am thinking of contructing a two dimensional Array where myArray[0][0] will be the first match like myArray[URL][0] the second element the second match. myArray[URL][1] and so on. So then I would iterate through the second dimension of the array. Will this work? I am thinking that it won't...
When I press F5 (debug) in Visual Studio 2010 Express, I get the following error message:
Unable to start debugging on the web server. IIS does not list a web site that matches the launched URL.
This happens only when I am trying to make use of the option "Use custom server".
I got both the host file and the IIS bindings set up. The server that I specified is working in the browser.
