c# - Need help with LINQ query -

-

मेरे पास निम्न श्रेणी है: 

  आंतरिक वर्ग ModuleScrap {public System.DateTime ReadTime { प्राप्त; सेट; } सार्वजनिक स्ट्रिंग ScrapReason {get; सेट; } सार्वजनिक Int16 NetScrap {get; सेट; }}   
 मैं एक LINQ क्वेरी के साथ कुछ मदद का उपयोग कर सकता हूं जो कि सभी पंक्तियों को कई सीमाओं (जो कि आसान हिस्सा है),  ScrapReason  पर समूह के बीच प्राप्त करता है और निर्धारित करता है प्रत्येक समूह के लिए  NetScrap  का योग मुझे LINQ में समूह के साथ बहुत अनुभव नहीं है।   
 
 
 ऐसा कुछ, मुझे संदेह है:  
  var query = स्क्रैप में स्क्रैप से जहां स्क्रैप। रीडटाइम & gt; = minDate & amp; amp; स्क्रैप। रीडटाइम & lt; = स्क्रैप द्वारा एक्सचेंज ग्रुप स्क्रैप। स्क्रैप रीजन में जी का चयन करें नया {कारण = जी। के, कुल = जी। एसयूएम (एक्स = & gt; (एनए) x.NetScrap)};   
 ध्यान दें कि  int  कास्ट क्योंकि  int16  मानों के लिए परिभाषित नहीं है एक विकल्प समूहिंग को बदलने के लिए है:  
  var query = स्क्रैप में स्क्रैप से जहां स्क्रैप। रीडटाइम & gt; = minDate & amp; amp; स्क्रैप। रीडटाइम और एलटी; = एक्सचेंज ग्रुप (इंट) स्क्रैप.नेट स्क्रैप द्वारा स्क्रैप। स्क्रैप सीज़न में जी का चयन करें नया {कारण = जी। के, कुल = जी। एसयूएम ()};   
 वे एक ही परिणाम देंगे - यह सिर्फ एक बात है जिसे आप पसंद करते हैं।

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c - Selecting a file randomly from a file system -

-
This question is related. I need to work on files and directories randomly as a file logic, such as rename, write, read etc. What I was planning to do, was to list all the files and directories along with their paths randomly to choose from this list. But, as the files and directories are created and destroyed in the actual file system, the list should also be updated. I am able to update the list and keep it inadequate in this way and it should also be atom so that the operation can not access any file later that was removed from the previous operation. Can you suggest that there is a different way of choosing files..to somehow integrate it with the file system ... but how do we know about the files? Thanks I'm Michael J. Barber's answer has found something particularly interesting, but due to my dragon ignorance I can not follow it completely You do not want to try to keep a list of files, when the file system is ok you should be able to correct it from C.
