c# - WinForm for creating ADO.NET Entities that have relationships with other entities -

-

I am very new to the ADO unit framework, and I am looking for the best practice

here The scenario is: I have a database with a person table and a address table. In person , there is a foreign key that refers to the primary key of the address , an auto-expand int first, I have the VS. 2010 has prepared an ADO unit model, and it is certain that the relationship is understood by the IDE.

Now I want to create a Windows form that gives the user the basic information of person and address . Normally, I can simply drag the person unit to blank windows form, and VS 22010 will automatically create required fields with the binding. But when this form fills by the user, I have to do extra work to ensure the following:

  1. Form address is part address < / Code> table
  2. has saved the person information, with the primary code saved in the person table address Made in 1.
  3. The user never touches / looks at the primary key.

I think my illusion is coming from the fact that I expect the IDE to do more coding than that; If I had to hop it as soon as possible, then maybe I would add a click event to the "Save" button, which first calls to SaveChanges () on the person by person is. Is this the best practice, or is there a more acceptable way of doing this?

You should not do too much, but you should contact the person (usually different / delete) To handle correctly the scenarios taken), the datachaintext should call SaveChanges.

You should simply remove all the control (columns) related to the key.

Do you have a specific problem?

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...
