Anonymous Delegate lifetime scope

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :WPF

If one defines an anonymous delegate, say, inside a function that uses a local variable of that function but the anonymous method can be called outside the function(say it is added to a list) then how is the local variable used by the anonymous delegate?


A test shows that the variable does have the correct value which I assume is because it is not GC'ed. It also showed that the variable has the last value(right before the function call ended rather than the before(which is generally how you think about it)).


This seems highly error prone but I guess is acceptable.


But how is the stack itself for the function defined? Is the function not GC'ed either?

It seems one has to be extremely careful when using non-local variables inside the definition of an anonymous function. As far as I can tell it is useless to do so(Since it is outside the scope of the function) and an error warning show be thrown?

(Note I am not talking about calling an anonymous function but defining it)

Tuples, Anonymous Types, and Concrete Types

Tuples can save you a great deal of repetitive tasks. They can also lead to completely unreadable code in a language like C#. Tuples are data values that contain N items. The .NET framework supports tuples containing 1 to 8 members. To use tuples with more than 8 members, you use another tuple for the member of an octtuple

'Model' cannot be declared in this scope


I have a complex partial view (ugly stuff), the view page has this line:-

C# 2.0: Create Elegant Code with Anonymous Methods, Iterators, and Partial Classes


C# 2.0 introduces a wealth of exiting new features, such as generics, iterators, partial classes and anonymous methods. While generics are the most talked-about feature especially for former classic C++ developers, the rest of the new features are important additions to your .NET development arsenal, enhancing power and improving overall productivity. This article is dedicated to all the new C# 2.0 capabilities besides generics to give you a good overall picture of the upcoming features.

Remoting: Managing the Lifetime of Remote .NET Objects with Leasing and Sponsorship


Leasing and sponsorship is the solution for managing the lifecycle of a remote object in .NET. Each object has a lease that prevents the local garbage collector from destroying it, and most distributed applications rely upon leasing. There are several ways in which objects and clients can extend the lease, including dedicated sponsor objects. In this article, the author explains leasing, shows how to configure it, and how it relates to the various remoting activation models. He then discusses design guidelines and options, along with their impact on throughput and performance. Additionally, he introduces a helper class used to automate the management of lease sponsors.

FAST Search for SP2010 scope setting works but not getting results.



I am trying this from last two days , but it does not work. I have created two scopes for FAST Search Query SSA , they appear in search center , but I am not getting any results back. I see them being fired in the FAST query log.

First one is a simple one:

New-SPEnterpriseSearchQueryScope -SearchApplication "FAST Query SSA" -Name DCO -Description "All DCO Documents" -DisplayInAdminUI 1 -ExtendedSearchFilter "ContentSource:DCO"

Content source is a managed property. and i can just query "contentsource:dco" from the text box which gives me results.

When I fire the query i see it in FAST Search query log

"GET /cgi-bin/search?qtf_keyword:context=ssgid%3a%3a4d020606-8532-45d8-b09a-db11283cccb4%7cSPS-Location%3a%3a%7cSPS-Responsibility%3a%2c%3a%7c&rpf_navigation:hits=50&rpf_navigation:enabled=True&spell=suggest&qtf_parsekw:timezone=10&type=kwall&qtf_teaser:dynlength=185&resubmitflags=8192&language=en&query=CASHIERING&sortby=%2bdefault&qtf_lemmatize=True&offset=0&version=

Top-Level Search Scope not showing in Sub-Site


I've got a site 'B' created under site 'A' in SharePoint. When I'm at Site A, I can search and find things that exist in both A&B. However, when I'm in B, the 'highest' search scope I can pick is 'B.' I'd like to be able to select one step higher so that I can search A&B from any page. Is this possible?

Items count in scope "not available" in on WFE while it is correct in another WFE

Recently, we added a new WFE in the farm to do load balance. After installation, the search is not working occassionally(almost 50%). It apparently hits the new server. The error message:
Your search cannot be completed because of a service error. Try your search again or contact your administrator for more information.

I checked the Items count on view scopes. It is correct on old WFE, while it is "not available" on new WFE.
 In the Office Sharepoint Server Search Seveice seeting, I checked "Use this server for indexing content" and "use this server for serving search queries". I had ever tried to uncheck ""use this server for serving search queries". It is not working, either.

Any suggestion?

Anonymous Web Site receives "The request failed with HTTP status 401: Unauthorized"


I set up a test website on my local box and was able to access sharepoint search using the querySearch web service from SP.  After I got it all working properly I transferred the code to the target website that is set up with anonymous access for all people on the fab floor.  However from this website I keep getting the 401 error.  It can't be SP because the same code worked from my local website "localhost".  Any suggestions?  we don't want to have to have the fab people log in so we can't not have the box anonymous.  I would appreciate any suggestions very much!!!

With Anonymous access disabled, is there any way to use an AJAX-enabled WCF Service?

I have a website where anonymous access is disabled but I want to user an ajax-enabled WCF service. Configuring the service's binding security to use "TransportCredentialOnly" with clientCredentialType="Windows" seems like the obvious thing to do; indeed, many posts in various places suggest this approach. Unfortunately, however, it doesn't work. I always get the error "Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service." How can I configure the service to function correctly. I'm running IIS 7.5 with .Net framework 4.0. Thanks.
