c++ - What are lookup rules when calling function from lambda? -

-

निम्न उदाहरण VC ++ 2010 में सामने आई समस्या को दर्शाता है: 

  वर्ग फ़ू {टेम्प्लेट & lt; class T & gt; स्थिर टी फू (टी टी) {वापसी टी; } सार्वजनिक: शून्य परीक्षण () {ऑटो लैम्ब्डा = [] () {रिटर्न एफू (1); }; // कॉल करने के लिए Foo :: foo & lt; int & gt; लैम्ब्डा (); }};   
 वीसी ++ का उत्पादन:  त्रुटि C3861:  'foo' : पहचानकर्ता नहीं मिला   
 अगर मैं कॉल को अर्हता प्राप्त करता हूं Foo:  Foo :: foo (1);  तब यह उदाहरण एक चेतावनी के साथ संकलित:  चेतावनी C4573:  'foo :: foo'  के उपयोग की आवश्यकता है संकलक को  'यह'  पर कब्जा करना है लेकिन मौजूदा डिफॉल्ट कैप्चर मोड इसकी अनुमति नहीं देता   
 इस मामले के बारे में मानक क्या कहते हैं? अयोग्य नाम होना चाहिए? क्या योग्य नाम के लिए  यह     
 
 
 पर कब्जा करने की आवश्यकता है? कई मामलों में रिपोर्ट देखें:  
  
  
 जैसा आपने पाया है, स्पष्ट प्रस्ताव उसे नाम ढूंढने की अनुमति देता है। इसके बारे में एक अतिरिक्त चेतावनी है जो एक कंपाइलर त्रुटि भी है (नाम का समाधान इस तक पहुंच की आवश्यकता नहीं है, हालांकि मैं देख सकता हूं कि एक कंपाइलर कार्यान्वयन की आवश्यकता कैसे हो सकती है) - हालांकि यह एक अलग बग है माइक्रोसॉफ्ट ने इसकी पुष्टि एक बग होने के लिए की है और अगले रिलीज के लिए जाहिरा तौर पर एक फिक्स तैयार किया है।

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

mysql - Formatting problem with PHP DateTime Difference when used as part of an equation -

I am trying to write a simple invoicing system. I want to use the Datetime Diff to calculate the cost of each invoice. I have so far: / * In this example $ dayLength and $ ratePerSec is not really the case, but now we use the hypotethical values ​​of 8.0 and 0.0054 Will * / $ date1 = new date time ("Time 1 Form Database", [DateTimeJonof Chase]); $ Date2 = new date time ("Time 2 Form Database", [Datetime Joneof Choice]); $ Diff = $ date2- & gt; Diff ($ date1); $ LenInSec = $ diff- & gt; Format ("% y") * 365 * $ dayLength * 3600 + $ diff- & gt; Format ("% d") * $ dayLength * 3600 + $ diff- & gt; Format ("% H") * 3600 + $ diff- & gt; Format ("% i") * 60 + $ diff- & gt; Format ("% s"); $ Cost = $ lenInSec * $ rate per second; When I try to output cost using $ lenInSec generated from the Deltaime Diff, I actually get weird results. Occasionally, in 1 and 3 out of 1 to 3 times, I get the...

Mysql Local server hardware -

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...
