Let's say in ASP.NET you have a base page class which defines a private Page_Load method which handles Page.Load. All aspx pages in your project inherit from this base page class. In this case the aspx pages would be able to call this private method. However it does not feel right that private methods can be called outside its own class? If so, privates methods cannot be hidden from outside?
View 1 RepliesI want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly
Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll")
assembly = System.Reflection.Assembly.LoadFile(assemblyName)
assembly.GetType("myClass").Getmethods(Bindings.NonPublic)
assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
I got this security warning ReviewVisibleEventHandlers(CA2109)for all event handler methods that are present in Global.asax.cs file(Application_Start,Session_Start,Application_BeginRequest,Application_EndRequest,Application_AuthenticateRequest,Application_Error,Session_End,Application_End.
I am trying to fix this warning by marking all event handler methods that are present in Global.asax.cs file as private. Does it result in any side effects in web application execution?
here is the code, where i am confused what to write in all the properties and functions of the base class stream?

Recently for a class to implement unit test for one of its private methods I used PrivateObject by creating private accessor instead of refelection, to which i received a code review comment as below
"My main concern with Private Object is the use of object[] in constructor. It replaces strong typing enforced by compiler with JavaScript-style run-time error detection.Consequently , personally, I would not recommend it."
Comments above confused me beacuse as per my understanding reflection also needs the object[] to invoke any method.
I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

I was hired to do some contract work for a short contract. I am looking at this code on this Aspx web form. What they do is load the labels for a radio button list from an ObjectDataSource object. Well this is the first time I have ever heard of an ObjectDataSource. The problem is that I don't even know where this object is pulling data from. With a SqlDataSource object, I can easily view the flyout menu to see the sql query where the data is being pulled from. Anyway, I need some figuring out where objectDataSourcePlanType lives and where it is pulling data from. I know I can't list the entire project, but I am sure someone who is familiar with ObjectDataSource

I am trying to use the concept of Single Sign On (SSO) in my asp.net application.
for the purpose i have created a main domain say
mydomain.com.
now i have 2 subdomains
sub1.mydomain.com & sub2.mydomain.com.
I am running these very fine. But now I want to have a SSO for my domains. For the same have
googled lot and found some stuff such as adding machine key to web.config and specifying domain names in cookies.
But it is not at all working for me. when I specify the domain name for cookies i am unable to sign out.
I am using FormsAuthentication in asp.net.
Following is the code I have in my web.config.
[Code]....
I have the same code in web.config of each domain.
I have placed the code for each domain in different directory on my website.
for ex. mydomain.com ---------> F:/HostedSites/mydomain
sub1.mydomain.com ---------> F:/HostedSites/subdomain1
sub2.mydomain.com ---------> F:/HostedSites/subdomain2
my Authentication code is
[Code]....
and sign out code is
[Code]....
Can anybody tell me where exactly I am wrong ? what changes do i need to do at server end also.
I am checking this on my testing domain ie. mydomain.tv. can this be a problem ?
I tried to extract text from images using ocr concept with MODI.In vb and console application it will work fine but i have an error when i applied my code in asp.net ....
Code:
string name = fileupdImage.FileName;
fileupdImage.Visible = this.fileupdImage;
fileupdImage.SaveAs(Server.MapPath("images/" + name));
string path = "images/" + name;
[Code] ....
Error occurred in following line as COM unhandled exception.
doc.Create(name);
I dont know why this error occured...
I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
i want source code about remember my password using cookies concept.
View 4 RepliesI am using asp.net mvc 2.0 to implement shopping cart application.My situation is , I have a order page, there i am adding the products to the Cart.Below it will show the Cart total.Next i will go to the shopping cart page to delete or editing the items.In this page it will show the same cart total as in the Order page.
But once again if i go back to the Order page to order some more products to the cart,the cart total in the order page is showing 0 amount. This is my Shopping cart controller action method,
public ActionResult ShoppingCart(int eventID)
{
Event e = eRepository.GetEvent(eventID);
var cart = Stalbans.Models.ShoppingCart.GetCart(this.HttpContext);
[Code]....
So once i will go to the shopping cart page from the order page and again coming back to the order page it has to show the same cart total. Actually data is persisted in the cart total but it is not showing .Because if you add one more item its amount will added to the existimng cart total and then shows the current cart total. So for the first time i click back at that it has to show the already existed cart total in the cart total value.
Here is a conceptual questions that I was going over the last few days. I have a simple application that I want to turn into a hosted solution.
My take on it is that in a sense each record in the database would have its own ID representing the hosted instance of the application, rather
than installing the application each time a new one is needed. Then I can easily differentiate between the instances, however I don't want to
store the instance ID in a session (bad for URL back links etc.) and don't really want to add it as part of the URL.
What would you suggest ?
Another part of the question would be how to pragmatically create a sub-domain representing the application instance, however that's a
Whole different question J
Am implementing the threadpool concept and have doutbt in threads being created.
[Code]....
Initially i gave (1,1) in semaphores and only one thread was created and it did only one task, and (5,5) created one thread and it used for all the times.
Is ter anything wrong in wat i did or any other way of doin other than semaphores. And mainly wat abt the remaining 20 threads in threadpool? its a waste of CPU right. Can i create only 5?

View 1 Replies what is best to use in CTP 5 for inheritence. Ive heard of 3 ways of doing it. (This is indirectly addressed to Serenarules )
Table per Hierarchy ?
Table per Type ?
or able per Concrete Type ?
For those who wondering what the hell is that.. refer to http://weblogs.asp.net/manavi/default.aspx which is a nice blog about inheritence and polymorphism in CTP 5.
All my controllers inherit from a BaseController that has an ActionFilter attribute:
[AnalyticsData]
public class BaseController : Controller {}
public class AccountController : BaseController {}
Some of my Actions in my controllers reuse the AnalyticsData ActionFilter:
public class AccountController : BaseController
{
[AnalyticsData(Page="AccountProfile")]
public ActionResult Profile()
{
// return View
}
}
I notice that the AnalyticsData ActionFilter only runs once. This is a good thing and I only want it to run once, but I'm wondering how that happens. If I set my breakpoint inside the OnActionExecuting:
public class AnalyticsAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// break point set here
}
}
only gets hit once when AccountController serves it Profile view. How do ActionFilters and/or Attributes work that [AnalyticsData(Page="AccountProfile")] on the Action overrides/replaces [AnalyticsData] on BaseController?
I want to bind grid using Bindlist(Generic class) and also ensure it does not have an impact on performance of the page.
View 2 RepliesI'm a junior programmer, i do not get the concept of MVC! My method of coding is seperating my application design into 3 layers:
Presentation Layer
Business Layer
Data Access Layer
I find it very practical to a junior developer or at least to me, so i do not really get the point of MVC since i believe MVC just tries to separate logic from UI. Right?
I decided to have this book to help me have a better idea on code design:
