years of experience with Ruby on Rails, or refuse to consider someone for a Windows API job when they only have Win32 on their resume. The reason recruiters do this is because it s easy, it can be computerized, and it s the only way they know how to judge developers. For almost all software development positions, though, it is the worst possible way to hire. Our philosophy is that we re hiring for the long term, and any technology you happen to know right now may well be obsolete next year. Furthermore, some of these technologies are very easy to learn. If I needed to hire someone to do Ruby development, someone with extensive Smalltalk and Python experience who had never even heard of Ruby would be a lot more likely to be successful than someone who read a book about Ruby once. For someone who is basically a good software developer, learning another programming language is just not going to be a big deal. In two weeks, they ll be pretty productive. In two years, you may need them to do something completely different in a programming language which hasn t even been invented. The keywords section of a resume can t be trusted much, anyway: every working programmer knows about these computer programs that filter resumes based on keywords, so they usually

gain more control over how edits are processed. This also enables the additional button editing UI on the DataForm control as shown in Figure 9-20.

Figure 9-20. Final UI for Recipe 9-8 Clicking the Edit button (the pencil) on the Customer Details DataForm control allows the user to perform CRUD operations. You configure the control explicitly to display all of the buttons in the constructor for MainPage after Initialization. The only other item to cover is the Save to Server button. When you perform edits using the DataForm, they exist on the client in the form of changes to the object representing each database record. Because you disabled AutoCommit, you need to manually send any pending changes, as shown in Listing 9-6.

Before saving the user s submission, we should confirm two things: whether the user passed the CAPTCHA validation and whether the user submitted an image file. The code to confirm these items is shown in Listing 6-13.

Listing 9-6. Recipe 9-8 MainPage.Xaml.cs File using System.Windows; using System.Windows.Controls; namespace Ch09_LOBApplications.Recipe9_8 { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); CustomerDataForm.CommandButtonsVisibility = DataFormCommandButtonsVisibility.All; } private void ButtonCommitToServer_Click(object sender, RoutedEventArgs e) { if (CustomersDomainDataSource.HasChanges && !CustomersDomainDataSource.IsBusy) CustomersDomainDataSource.SubmitChanges(); } } }

When you add a Domain Service to a web project, you have the option of generating a metadata class. The metadata class is a partial class that allows developers to apply validation configuration without having to worry about the classes getting regenerated automatically if the underlying model changes. The data annotations sit in the System.ComponentModel.DataAnnotations namespace. There are three categories of attributes in this namespace that can be applied to entities, validation attributes, display attributes, and data modeling attributes. Table 9-1 has a list of the validation attributes that can be applied to entities via the metadata class.

Allows the developer to identify a custom method in code to validate a property. This is an alternative to creating a custom validation attribute. Has a related enumeration named DataType that has pre-configured data types on it such as EmailAddress, Phone, etc. Validates the value configured on a property to ensure it is part of the identified enumeration type. Allows the developer to specify a regular expression for validation.

Identifies that the property is required. Specifies a minimum and maximum character length. Abstract base class for validation attributes.

public void submit() { Textbox tbxverify = (Textbox)getFellow("verify"); String verify = tbxverify.getValue(); Captcha captcha = (Captcha)getFellow("captcha"); if (!captcha.getValue().equalsIgnoreCase(verify)) { try { Messagebox.show("Incorrect verify string, try type the charcter in the image.", "Error", Messagebox.OK, Messagebox.ERROR); } catch (InterruptedException e) { throw UiException.Aide.wrap(e); } finally { captcha.randomValue(); //change a value for next try } return; } if (_img == null) { try { Messagebox.show("Please upload your pet picture.", "Error", Messagebox.OK, Messagebox.ERROR); } catch (InterruptedException e) { throw UiException.Aide.wrap(e); } return; }

The two available extension points for developers are to create a custom validation attribute that inherits from the ValidationAttribute base class or create a custom class method and designate that method using the CustomValidationAttribute class.
