c++ code: class or structure: difficult to understand -

-

संभव डुप्लिकेट:

मैं संरचना के लिए किसी शीर्षलेख फ़ाइल को देख रहा हूं, लेकिन ऐसा लगता है कि फ़ंक्शंस इस संरचना का एक हिस्सा हैं ... तो फिर यह एक वर्ग है, लेकिन कैसे रोकना है? या उपयोग करें? 

  संरचना रिकॉर्डिंग {फ़्लैग मोड; अहस्ताक्षरित लघु अंतराल; अहस्ताक्षरित लघु बचत_साइकिल; आभासी शून्य SavetoFile (फ़ाइल * फ़ाइल, बूल नियंत्रण, PhaseData * __ चरणडेटा = नल); वर्चुअल बूल लोडफ्रेम फाइल (फाइल * फ़ाइल, बूल नियंत्रण, फेजडाटा * __ चरणडेटा = नल); };    
 
 
 सी ++  वर्ग  और  struct  समान हैं, सिवाय इसके कि पूर्व के लिए डिफ़ॉल्ट एक्सेस स्पेसिफायर  निजी  है, जबकि बाद के लिए यह  सार्वजनिक  है।  
  class बेस {/ * .. * /}; वर्ग फू: बेस {int i; }; संरचना बार: बेस {int i; };   
 उपरोक्त कोड में  Foo  निजी कोड से  बेस  से प्राप्त होता है, जबकि  बार  ऐसा सार्वजनिक रूप से करता है इसी प्रकार,  Foo :: i  निजी है जबकि  बार :: i  सार्वजनिक है ध्यान दें कि दोनों मामलों में  i  की दृश्यता के लिए विरासत से कोई लेना-देना नहीं है, यह वही होगा, भले ही  Foo  और  बार  नहीं किया  आधार  से वारिस।  
 इन अंतरों के अलावा, जो भी आप एक के साथ कर सकते हैं, आप दूसरे के साथ भी कर सकते 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...

c# - Using Vici cool Storage with monodroid -

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
