I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc.
Is there a way that I can accomplish namespace functionality from inside a class?
I have a .net project whose part of the functionality is xls transformation. I now want to move that functionality away from the main project to a separate class library project.
I have no problems moving classes and accessing them, but part of the resources that I wanted to move were xslt files that define the transformations. Those files were originally located in the special asp.net folder: App_Data and then accessed using Server.MapPath(~/App_Data/XSLT/anXsltFile.xslt)
I wanted to move those files to that separate library as well, but not sure how to approach it, and how to access those files within the class library.
I cannot use foreach with datable.
In that case if i wish to extend or create a class for this functionality
how do i proceed?
Can anyone tell me how to show alert message inside the .cs file of class library project in c#? I am calling a method of cs file in classlibrary project. Whenever the control comes to the alert message statement inside the method, alert message should be shown on the web page(aspx) and the next statement to the alert message statement should not be executed.

View 3 RepliesWhat cool functionality and methods do you add to your ASP.net BasePage : System.Web.UI.Page classes? Here's something I use for authentication, and I'd like to hear your opinions on this:
protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
// Authentication code omitted... Essentially same as below.
if (_RequiresAuthentication && !(IsAuthorized))
{
RespondForbidden("You do not have permissions to view this page.", UnauthorizedRedirect);
return;
}
}
// This function is overridden in each page subclass and fitted to each page's
// own authorization requirements.
// This also allows cascading authorization checks,
// e.g: User has permission to view page? No - base.IsAuthorized - Is user an admin?
protected virtual bool IsAuthorized
{
get { return true; }
}
My BasePage class contains an instance of this class:
public class StatusCodeResponse {
public StatusCodeResponse(HttpContext context) {
this._context = context;
}
/// <summary>
/// Responds with a specified status code, and if specified - transfers to a page.
/// </summary>
private void RespondStatusCode(HttpContext context, System.Net.HttpStatusCode status, string message, string transfer)
{
if (string.IsNullOrEmpty(transfer))
{
throw new HttpException((int)status, message);
}
context.Response.StatusCode = (int)status;
context.Response.StatusDescription = message;
context.Server.Transfer(transfer);
}
public void RespondForbidden(string message, string transfer)
{
RespondStatusCode(this._context, System.Net.HttpStatusCode.Forbidden, message, transfer);
}
// And a few more like these...
}
As a side note, this could be accomplished using extension methods for the HttpResponse object. And another method I find quite handy for parsing querystring int arguments:
public bool ParseId(string field, out int result)
{
return (int.TryParse(Request.QueryString[field], out result) && result > 0);
}
I have a class file called ShoppingCartClass.cs. Inside ShoppingCartClass I have a method called CanadaPostShipping.
CanadaPostShipping get passed a lot of variables and then builds an xml, sends it to CanadaPost url and gets back an xml file with the shipping rates.
I would like to pass the xml back to my webpage so in my web page I can check that it has status ok and then extract the information I need.
My testing calling routine looks like this:
[Code]....
The start of my CanadaPostShipping routine looks like this
[Code]....
This is my current ending spot in CanadaPostShipping....where I am getting back the correct xml from CanadaPost
[Code]....
As you can see I am saving it to my thumbdrive.....
What changes would I have to make to my calling routine and the method in the class to return xml "mydoc"?
I'm using nested master pages for my site, is there a way I can use the namespaces once in the master?Currently I have to add the namespaces to whichever page I need them in.
View 1 RepliesOne small doubt in the way it works for C#Where does local variables of a method inside a class get stored?Heap? - If yes, then why do we have to explicitly initiate them?Stack?- Then how does the allocation of them takes place once we make a object of the same class using new - would it make the member variables of class to be allocated on heap and local variables of member functions (of the same class) on stack.
View 4 RepliesI understand the problem of the static variable inside a class in the web application, now I try to create a simple class to deal with SQL Server for example, so I created Static Method inside this class, this static method used in insert, update and delete from database, I wonder if this is safe, and there is no problems will appear ?
View 10 RepliesI have a web site that was done in asp.net 2.0 along with visual studio 2005. I've recently upgraded to VS 2008 and I'm haveing an issue with the namespaces in the web.config file not registering. Specifically, references to system.web and microsoft.visualbasic.
View 3 RepliesI've recently switched over to using the Razor view engine, and I want to specify a namespace to use in a view. I've tried adding an entry to the Web.config file, ie:
[Code]....
But none of my views recognise any of the classes inside that namespace, so I have to declare the namespace in every view that needs it. why the Web.config approach isn't working?
what are the namespaces that should be well known by a fresher to initiate asp.net learning, what is the main use of a namespace. what is the use of 'args'
View 4 RepliesASP.NET MVC's MapRoute method has a parameter named namespaces. From looking in the code, I see that this parameter is saved in the Route object
in DataTokens["Namespaces"].
It seems to me that it has some meaning... anyone knows what is it for?
I read an article here to find the solution to my problem. But I found that it is not working for me. Whenever I tries to use any function I have to add same namespace on every page. by doing using System.Web.UI . Can I also use it for namespace that is being created along with an application. i.e. Library is an another namespace that lies in App_Code folder not as an assembly.

I'm working on an ASP.NET webapp using the MVP pattern, and as I'm organizing my files I'm wondering - are there conventions on folders within projects and how they relate to namespaces?
I have a bunch of controls and a bunch of pages, and I was going to throw them into Controls and Pages folders with subfolders, but I didn't know if it was bad form to do this if I wasn't also going to seperate them out into namespaces.
im creating a class library, and adding all the necessary references for the source files contained in it.
Now, off the bat, there were over 300 compiler errors complaining about missing namespaces.
The library will now compile after i just added all of the System.* references, however this is obviously not the best way.
I.e. if a classes needs using System.Web.Script;, there is no System.Web.Script reference, how would i find out which one of these references contained it? System.Web didnt.
I need to add this namespace to my c# file:
using System.Data;
Is there a way to automatically add this to newly created pages in c#.net?
I don't want to add this namespace to new pages.
How do you reference an asp.net control on your page inside a function or a class.
private void PageLoad(object sender, EventArgs e)
{
//An example control from my page is txtUserName
ChangeText(ref txtUserName, "Hello World");
}
private void ChangeText(ref HtmlGenericControl control, string text)
{
control.InnerText = text;
}
Will this actually change the text of the txtUserName control?
I tried this and is working
private void PageLoad(object sender, EventArgs e)
{
ChangeText(txtUserName, "Hello World");
}
private void ChangeText(TextBox control, string text)
{
control.Text = text;
}
Is it possible to say something to the effect of 'SomeClass.Out.WriteLine("hello world")' and have it actually show up for the browser to render? I ask, because I notice that the HtmlHelper BeginForm implements IDisposible. So at the end of the using block, a closing tag is written to the browser.I am not saying I would use this practice, as it seems like a bad idea, but I just want a better understanding of what is going on under the hood of C# ASP MVC.
View 1 RepliesI guess I might be missing something easy (or not) here. I have a class in App_Code which do some validations over Session and Request.Url, till here it's working fine. But then I need to get the actual page title. I know it's simple to get it in the page's code behind, but could I get it in a separate class like it is on my scenario?

</asp:Repeater>
</ul>
Now there are five items in the ItemTemplate of this repeater..what i want is to set class of each of the anchor tags as "mySprite id1,mySprite id2 , mySprite id3 and so on.."
for that I did this in code behind...
for (int i = 1; i < 6; i++)
{
Name.Attributes.Add("class", "sprite id" + i);
}
Now when I view page source, ALL my anchor tags have got class set as class="sprite id5"
I am referencing some classes in my _layout.cshtml file and I have the namespaces in my Views/web.config <pages><namespaces> section and the layout page does not resolve. If I put @using statements in the layout page, it works fine. Shouldn't the layout page respect the web.config section?
