मेरा लेआउट संरचना निम्नानुसार है 

  लेआउट ए -------- ------------------------------ | ------------------------------- | | | लेआउट बी | | | | | | | | | | | | | | | ------------------------------- | | | | | | | --------------------------------------   
 नीचे लेआउट बी एक और दृश्य है लेआउट ए में एक टुकड़ा एफ 1 होता है जो बदले में लेआउट बी में एक टुकड़ा F11 जोड़ता है। अब कभी-कभी मैं टुकड़ा F11 में टुकड़ा F11 को प्रतिस्थापित करना चाहता हूँ, F12 और कभी-कभी मैं किसी एक टुकड़े के साथ लेआउट ए में टुकड़ा F1 को बदल देता हूँ F2 जब तक मैं बदल रहा हूँ लेआउट बी के अंदर टुकड़े यह ठीक है। लेकिन मुख्य समस्या तब आती है जब मैं F2 के साथ F1 को बदल देता हूं। परिदृश्य पर विचार करें जहां F1 के अंदर मेरे पास F11 है अब मैं एफ 2 के साथ एफ 1 को बदलता हूं। अब जब मैं वापस कुंजी F11 हिट अब और दिखाई नहीं है। यहां समस्या क्या है और मैं उसे कैसे प्रबंधित कर सकता हूं

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.

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...
