android - difference between finish() and killProcess by myPid(); -

-

I've always heard about ending any activity or android.os.Process .killProcess (Android.os.Process.myPid ());

First & lt ;: I think what is the difference between what is accurate?
The second What is the best thing about them?

Third For some time when we pass data through intent, then will the data be lost?

before What is the exact difference between them?

android.os.Process.killProcess (android.os.Process.myPid ());

Completed will delete the activity from which you End

Second <: What is the best thing about them?

This depends on what you need, but it killProcess

the third & lt; : Some time when we lose data from one activity to another, when we pass data through intent, data will be lost using the fin () or the kill process ?

Of course the process of killing! KillProcess will not return to the previous activity, it will kill all the activities launched in this process.

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...

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...
