I'm very interested in languages and their underpinnings, and I'd like to pose this question to the community. Are the following analagous to eachother in these languages?
C#
Foo bar = default(Foo); //alloc
bar = new Foo(); //init
VB.NET
Dim bar As Foo = Nothing 'alloc
bar = New Foo() 'init
Objective-C
Foo* bar = [Foo alloc]; //alloc
bar = [bar init]; //init
i have the following code in an asp.net mvc view.
<% = Html.DropDownList("Filter", new SelectList(Model.Items, "Id", "Name", 0), new { @id = "Filter", @class = "autoComplete1" })%>
i want to add an element at the top of the dropdown as the first item that says, "Please select".
do i have to add that into my Model.Items or is there a way i can add that element into the view and ignore the selection of that first element ??
I have written an application that basically gathers up a bunch of text and numerical data from the client PC and stores it as an object. Right now I'm implementing XML serialization so that the file can be saved.
The issue is now, how do I get this data to the server? I have a server running IIS 7 setup but I don't quite understand the ASP.net life cycle, so I'm not sure how to implement the receiving app.
What should I do?
Thanks
Hi Guys
I've been creating a lot of my own custom attributes in my XHTML documents lately, and am aware that because they are custom attributes, they won't validate against the W3C standard.
Isn't it true that I can specify my own DTD to make it validate? If so, can anyone tell me what's involved in doing this in an ASP.NET MVC app?
Thanks

Does anyone know how to check in ASP.NET (C#) if Facebook is scraping a page? I'd like to be able to check on the server side if the "browser" hitting the page is actually Facebook (e.g. when it grabs details when a user is attempting to share a link).
hi, I need to get a domain name if I have an IP address (e.g. I type 209.85.129.103 and the program should find out that is the Google address)
As far as I've figured out is get the hostname:
IPHostEntry IpToDomainName = Dns.GetHostEntry("209.85.129.103");
string HostName = IpToDomainName.HostName; //it returns "fk-in-f103.1e100.net"
but it's not that I want.
I don't know how to achieve that. Any ideas will be helpful

I'm relatively new to .Net 4 and I am creating my FIRST WPF application using a MDB as a backend datasource.
I designed my UI. I have a TextField (called Name), a Combobox (called Division) and a DataGrid (called dataGrid1).
The only problem I'm having is figuring out how to link my DataGrid to display data from the DataSource. and load the data in the Windows1_Loaded method.
Thanks
I am writing a windows forms application in C# and I create a RichTextBox (via code, not the designer). I am setting the AutoWordSelection property to false, but when I highlight stuff in the box, it still jumps to the boundaries of words, plus a space. Is this a flaw in .NET or am I doing it wrong?

In ASP.NET, what's the difference between building a project with in the Web.config and with Release mode in the Configuration Manager?
When would you use one and not the other?
in asp.net mvc , if i shove a dictionary or an array of objects in ViewData and read that in my view compared to creating a view model class that has that same data structure, is there a performance difference or other consideration or should i expect the same response time?
I think there are people who may be able to answer this, this is a question out of curiosity:
The generic CreateInstance method from System.Activator, introduced in .NET v2 has no type constraints on the generic argument but does require a default constructor on the activated type, otherwise a MissingMethodException is thrown. To me it seems obvious that this method should have a type constraint like
Activator.CreateInstance<T>() where T : new() {
...
}
Just an omission or some anecdote lurking here?
Hi All,
I have an application written in asp.net that I am accessing from a machine with Japanese OS, I use FileUpload component on a page and file path comes as C:\Directory\AnotherDirectory\FileName where it should have been C:¥Directory¥AnotherDirectory¥FileName because ¥ is separator for Japanese OS.
Any Idea how this can be fixed or any solution that you would recommend.
Hi
I have a website used by clients for reporting purposes and would like to give clients the option of my website reading their local database directly (instead of them providing data in a file format).
In most instances their database would be SQL Express setup on their localhost.
How can I connect to a clients local SQL server via my website, using asp.net / javascript etc? If the client provides their connection string properties, localhost would just refer to my server's localhost...
Thanks
