c# - Exchanging data between classes -

-

class = "text"> itemprop = "text">

I have a main square named main, in that main square there is a variable called state which type int in state variable There is a state id that tells the program what it is in (menu, instructions screen ...) in the main category I have the object started with the class of class. Now my question is, how the object has been told that the state has been changed (it is easy, I can make it very easily but the next part is giving me problems), and how the object can tell the main square Is that what he wants to switch states?

This is your question I understand,

  • The main is the controller class that invokes the Sprite example methods
  • state determines the method that is called on it Sprite example

    In this situation, the phantom should have a fixed asset in the class, which is named state (Preferably to be a int instead of a enum

    This is the responsibility of the example methods to update state variables. On completion of the execution of the example method, the collar can check the status that is in the example and then determine the next course of the appropriate action Please.

    A better approach is not to expose the state at all (unless there is no need to use it by external objects). In your case, it appears that the state is being used only to determine the method that is executed (I think you have a switch statement to do this ).

    If you want to cover a particular method based on your situation, then you can leave this decision for yourself as an example, instead of taking the decision of the controller, The method can be ( update () or Execute () ) that performs operations on the basis of operation context (like menu options, etc.). This method can execute the internal method based on the stable state member.

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. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

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...
