C++ Compiler Issues -

निम्न दो हेडर फाइलों को देखते हुए: 

  #ifndef EVENT_HANDLER_H #define EVENT_HANDLER_H #include & lt ; SFML / Window.hpp & gt; # शामिल करें & lt; एस एफ एम एल / विंडो / इवेंट। एचपी & gt; #include "window_handler.h" वर्ग EventHandler {सार्वजनिक: इवेंटहैंडलर (विंडोहाण्डलर और क्लास ओनर); विंडोहाण्डलर * एम_विंडोहैंडलर; निजी: bool m_leftKeyDown; बूल m_right किडाडाउन; Bool m_up केडीडाउन; Bool m_downKeyDown; अहस्ताक्षरित int m_mouseX; अहस्ताक्षरित int m_mouseY; }; #endif   
 और  <पूर्व>  #ifndef WINDOW_HANDLER_H #define WINDOW_HANDLER_H #include & lt; एसएफएमएल / सिस्टम। एचपी & gt; # शामिल करें & lt; एस एफ एम एल / विंडो.hpp & gt; #include "event_handler.h" वर्ग WindowHandler {सार्वजनिक: WindowHandler (); Sf :: विंडो m_app; निजी: इवेंटहान्डलर m_eventHandler; }; #endif   
 मुझे निम्न आउटपुट मिलता है:  
  खिड़की_हैंडलर से जुड़े फ़ाइल में: 6: 0, मुख्य सीपीपी से: 3: इवेंट_हैंडलर H: 13: 29: त्रुटि: अपेक्षित 'ए') ??? पहले और ???? टोकन event_handler.h: 15: 2: त्रुटि: एक खिड़कीहैंडलर एक प्रकार का नाम नहीं   
 जहां तक ​​मुझे पता है, हालांकि, मैं पूरी तरह से सब कुछ ठीक कर रहा हूं।   
 
 
 आपके पास एक परिपत्र निर्भरता है।  
 जब < कोड> window_handler.h  में शामिल है  event_handler.h  आपने  WINDOW_HANDLER_H  को परिभाषित किया है लेकिन वास्तव में उस बिंदु तक नहीं पहुंच पाया है जहां क्लास परिभाषित किया गया है जब  event_handler.h  को  window_handler.h  को शामिल करने का प्रयास करता है तो यह  WINDOW_HANDLER_H   
 
 के कारण नहीं है जैसा कि आपको बताया गया है, आपको आवश्यकता है  window_handler.h  के लिए शामिल करके और  
  class WindowHandler; को हटाकर  event_handler.h  में घोषित करने के लिए अग्रेषित करें;

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...

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.

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...
