c# - Cached item never expiring -

-

मेरे पास एक वर्ग है जिसमें निम्न गुण हैं: 

  सार्वजनिक शब्दकोश & lt; स्ट्रिंग, इंट & gt ; टिप्पणी की गई {{string cacheKey = "टिप्पणी की गई" प्राप्त करें; HttpContext c = HttpContext.Current; यदि (सी। कैचे [कैचकी] == नल) {c.cache.indert (कैशकी, नया शब्दकोश & lt; स्ट्रिंग, इंट एण्ड (), रिक्त, डेटटाइम.यूटीसीएनओ। एडसेंकेंड (30), सिस्टम। वेब। कैशिंग। नो स्लिइडिंग एस्पिरेशन, कैश इटैम प्रियरियरी। हाई, रिक्त); C.Trace.Warn ("नई कैश आइटम:" + cacheKey); } वापसी (शब्दकोश & lt; स्ट्रिंग, एट एंड जी;) c.Cache [cacheKey]; } सेट {HttpContext.Current.Cache ["CommentCounts"] = मूल्य; }}

ऐसा लगता है कि ट्रेस स्टेटमेंट केवल एक बार चलाता है, और कैश आइटम की समय सीमा समाप्त होने के बाद प्रत्येक 30 सेकंड नहीं। एकमात्र तरीका मैं इसे कैश्ड आइटम को ताज़ा करने के लिए प्राप्त कर सकता हूं एक कोड मौका बनाने और परियोजना को पुनर्निर्माण करना, जो स्पष्ट रूप से आदर्श से कम है।

मुझे क्या याद आ रहा है? पहले से धन्यवाद ...

संपत्ति का सेट हिस्सा शायद है कारण - कैश ["कुंजी"] = मान कॉल करने के बराबर है कैश.इन्सेर्ट के साथ नोआसोल्यूटएक्जीरेशन, नोस्लाइडिंग एसिपरेशन जिसका अर्थ है कि यह कभी भी समाप्त नहीं हो जाता है सही समाधान ऐसा दिखेगा: 

  सार्वजनिक शब्दकोश & lt; स्ट्रिंग, इंट & gt; CommentCounts {get {const स्ट्रिंग कैश} = "टिप्पणी की गई"; HttpContext c = HttpContext.Current; यदि (सी। कैचे [कैचकी] == नल) टिप्पणी कैंब्रिज = नया शब्दकोश & lt; स्ट्रिंग, इंट & gt; (); वापसी (शब्दकोश & lt; स्ट्रिंग, इंट & gt;) c.Cache [cacheKey]; } सेट {const स्ट्रिंग कैशकी = "टिप्पणी की गई"; C.Cache.Insert (cacheKey, value, null, DateTime.UtcNow.AddSeconds (30), सिस्टम। Web.Caching.Cache.No। स्लिपिंग एस्पिरेशन, कैशइस्टम प्रीरीरिटी। हाई, रिक्त); C.Trace.Warn ("नई कैश आइटम:" + cacheKey); }}

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.

.net - Self Tracking Entities (STE)'s and partial updates with EF4 and mVC2 -

-
I have an MVC2 app where I'm starting to use 'I'm looking for some explanation How updates should work. Background: If I have a blog entity with related category entities and related posts / comments, In MVC I am providing a view with main blog unit and categories but not related posts. When I post back the blog unit to the server, then I can see the related categories but not the post (because they were not in the view) back in the unit ordered on the server. In addition, there is a changing state of the blog unit's 'edited'. Then I'll try to call the implementer () and SaveChanges () to make an update to the unit and post it With FK fails due to relationships and the fact is that there are related posts in the database but I am returning back. With some more trials ... if I take a current example of the blog unit (with all related FK entities), while connected to the server (state = unchanged), modify the property (State = modified) and i...
