c# - Implementing Business Objects for a WinForms MVP application -

-

I am creating a new system from scratch and working on the design of the application. I'm looking at ways viable for my domain object modeling.

Some special about the project - it will be a big data entry, integrated in WinForms application, ESRI ArcMap (a GIS app). Data access should go through Arcampe's own Data Access Layers - Data is retrieved and saved through cursor style access. There is no problem obtaining this data, but I know, this organization excludes ORM devices as framework and NHibernate, because I can not interact directly with the database.

The WinForms application will follow a MVP pattern - View will be connected to the model. The presenter will also modify the model. Therefore, the domain object should support the following:

  • Change the notification
  • Changing the Tracking At the lowest level, I want to know whether my model has changed or not.

    <+++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++> Change the notification through the INotifyPropertyChange interface.

  • Change the tracking through an IsDirty property, which must be maintained manually.
  • ADO.NET datasets wrapped by POCOs .
  • + "Free"
  • + "

    which I have rejected :

    • The unit framework - I 'n is on Net Framework 3.5, so no code is already supported. As far as I know, domain is too messy to handle logic - Event Handlers.

      Are there any other good alternatives? Maybe code generation (any suggestions on the device?), Some frameworks? Words of wisdom, advice?

      POCOs just "dumb" data Are the transfer objects and There is no business in it, whatever the logic, they are not my models as they are another set of dumb objects that are close to my UI. I pumping the data out of my DTO in my data access layer, I pass the processing level to my service level, but they are only transferred to my presentations / controllers so that I can get my UI model Adequate information through the switch to models. For your case, I think it would be more logical, because you will have to go through the data access layer to ArcMap. You can keep data in your presentation level and keep an eye on it.

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...
