• Multiple Columns as Primary keys

  - by rockbala

  CREATE TABLE Persons ( P_Id int NOT NULL, LastName varchar(255) NOT NULL, FirstName varchar(255), Address varchar(255), City varchar(255), CONSTRAINT pk_PersonID PRIMARY KEY (P_Id,LastName) ) The above example is taken from w3schools. From the above example, my understanding is that both P_Id, LastName together represents a Primary Key for the table Persons, correct ? Another question is why would some one want to use multiple columns as Primary keys instead of a single column ? How many such columns can be used in together as Primary key in a given table ? Thanks Balaji S

• Put MFC CDialog in a WPF form

  - by splintor

  Hi, We are porting an MFC application to WPF, and will probably won't have time to port the entire application. The MFC app has many CDialog-based windows, and we are thinking of leaving some of these windows in MFC, and show them inside a WPF window, so we can control their modality from WPF. Is there an easy way to accomplish that? If not, can you recommend another way to handle this? thanks, splintor

• Django Inline formset for editing multiple related records at once - the right way to go?

  - by Bert

  Hi, When using inline formsets, how does one do paging? I'm using django 1.1. The situation I'm in, is that the user needs to be able to edit the related objects quickly and easily (which is why I think I should be using an inline formset). However, there can be a more than a hundred objects to edit, which makes a pretty large formset, so paging would make sense. Is there a better way to be doing this? Thanks Bert

• Is it better to create the db/tables programmatically or through a .db file in assets

  - by llappall

  Hi, does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets? What are the pros/cons of both approaches? I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste. Thoughts? Thanks! llappall

• How do I mock an object in this case? no obvious way to replace object with mock

  - by Tristan

  Hi there, Suppose I have this very simple method in Store's model: def geocode_address loc = Store.geocode(address) self.lat = loc.lat self.lng = loc.lng end If I want to write some test scripts that aren't affected by the geocoding service, which may be down, have limitations or depend on my internet connection, how do I mock out the geocoding service? If I could pass a geocoding object into the method, it would be easy, but I don't see how I could do it in this case. Thanks! Tristan
