c# - Breaking the .NET MEF import chain -

-

For this example, you might assume that the upper part is importing the class. By the time you import everything (i.e. ClassX), MEF works very well. Often you do not need to import because classb is in the same name space / file as a result the import chain is now broken and my logs are never created. In my example, Classbie Logger is trying to import the service, which may be the desire of almost all classes.

If anyone has the purpose / best MEF solution for this issue?

1) Once the import chain breaks down, then the import is never used again. Instead you will have to start constructing / constructing all types of constructor (i.e. new classbie) This works in this example, but it is messy if the intermediate classes are not used in the series.

2) Use the IceSwalker in system namespace to import Classbase, as far as I know that the Serverside (for example, the Prism Framework) is the only essence of dependency injection scheme. For example if classbie If ISISLL can import, then IOOGG can be imported into it.

3) Back to the previous Call Composabilities (Classbie). To prevent upper level on the basis of Classbie, I could apply Class B to ICB (ICOMXME), which will be sub-city importer after that it will be composed of upper portion for all ITM import on the container. I do not believe this objective solution This is because it has not been described or used in the MEF framework documentation.

4) Actually I'm out of ideas, please help ... 

  class squares {// will be imported within ClassX [Import] ClassX myClassX ; // will not be imported within the classroom! Var myClassB = new ClassB} class ClassB {// fails because Classbys have never been created [import] IOiggers Marlog; MyLog.Display ("Hello World"); } [Export] Orbit Class X {// Works - Imported on imported Classics [Import] iLogger Mylog; MyLog.Display ("Hello World"); }    
 
 
 Do you follow dependency injection patterns?  Do not break the import chain  In your application, a single structure should be root, where the components are wired together. Components should not be worried about achieving their reliance.  
 It is valid, in practice, you have to deal with the current code (and other developers suspected of DI) so that you do not always have to depend on injection "all the way down" in those cases as a global variable Expose the container and can pull the necessary dependencies from there.  
 To highlight a container globally, it is essentially a service locator pattern.

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...

c# - Using Vici cool Storage with monodroid -

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...
