c# - Determining from which View/UserControl a Command was called -

-

What is the definitive way to determine which scene (user control) was called?

For example, if I have two views, then each single view is tied to the modal, how can I decide how a specific command was called? Having a separate order for each scene will not make any difference in this scenario, because it is an external service that should be informed about the particular active view.

I assume that you call the command from userstrop, so if you say the method, example For some method, then as a method, a UserControl object is required to be taken as a parameter. In other words, you should be like something like: 

  some blank posts (User control U, other parameters ...) {if (u have some user controls) {\\ nothing do} And if ....}   
 and call this method on your user control:  
  some mode (this, .....) \\ This keyword will send a UserControl object if you say that method within a UserControl class, in other words it crosses itself as a parameter     The will

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...
