android - For Loop on ArrayList Exception -

-

I apologize for the limited title, but I do not know how to describe this problem I have a loop Which repeats through an array list with an array. One object management is a boolean that is set at a different point in time. The point of the loop is to go through the array list and remove each item as incorrect as a boolean. 

  if (! ArrayList.isEmpty ()) {int len ​​= arrayList.size}; (Int i = 0; i & lt; len; i ++) for {if array! }}}   
 For loop always leaves more than one object in the array. This is because because of the items removed in the array for loop cycles every time the LAN drops down and can cancel the loop before removing the object on the last object. I understand this problem, but I do not know how to fix it I have tried to do something like LAN + 1, but when I do something for it, this one index throws an output bond exception. any idea? Besides, is the best way to do what I am trying to do?   
 
 
 That you do not use methods that come after items you extracted.  
 for  (int i = arrayList.size () - 1; i> = 0; i--) {}   
 alternative form From, you can reduce the  i  to use the next code, and get rid of the  len  variable so that the end position uses the actual length.

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...
