Editor's Notes

• #2: Start the session by sharing the session objectives with the students.
• #3: Initiate the session by discussing with the students that there are people with different types of disabilities such as visual and hearing disabilities. In addition, discuss with the students that the users around the globe may be accessing the applications differently. While some of them may access applications on their desktops, some might access applications on their mobile devices. Also discuss with the students that all the users around the globe have different languages. Therefore, the applications that are designed must be capable of fulfilling the requirements of this wide variety of users. Such applications are known as accessible applications and can be developed easily by using VC#. Also discuss with the students that there are several guidelines for designing these accessible application. Discuss all of these guidelines with the students.
• #4: Discuss all of the properties listed on this slide for designing accessible options.
• #5: Reiterate the concepts taught earlier by asking the given question.
• #6: Using this slide, discuss with the students that International applications provide the flexibility to be used across the globe. But in order to design these applications, it is essential to include information about the date and time formats and currency symbols. Discuss the following example with the students: a sales monitoring application designed for users in United States uses dollars as their currency. The same application when used by users in UK, would create problems as the users in UK will require all the currency to be converted into pounds. But by using international application, the same application can be used in the United States with dollar format and in UK with pound format. Therefore, the advantage of creating international applications using VC# is that the user is able to get customized applications.
• #7: Using this and the next slide, discuss the structure of the International applications. Discuss with the students that the application is divided into two blocks, code block and the data block. The code block contains all the code, while the data block contains locale specific information. For example, the application when used in United States will have its currency in dollar. Whereas when the same application is used in UK, it will have its currency format as pounds.
• #9: Using this slide discuss the process of internationalization with the students. Discuss all the three phases : Globalization Localizability Localization Explain this with the help of same sales monitoring application example. Explain to the students that globalization involves creating a general sales monitoring executable application which is not specific to any particular culture around the globe. Localizability involves testing this sales monitoring application to ensure that it does not require any culture specific data and it can work independently. Finally, to use the application for a specific culture such as in United States or UK, the sales monitoring application will have to be localized.
• #10: Using this slide, discuss all the issues relating to the internationalization of applications. Explain the language issues to the students by taking the same example as given in the SG. This explains about the Arabic language which is written from right-to-left and hence can create problems while being used in an application. The formatting issues can also be discussed with the help of an example. The example that can be used to explain formatting issue is that of the currency. The currency keeps varying for most of the countries. The string related issues can be discussed with the students as discussed in the SG. Explain to the students that because of difference in language and alphabet set, the appearance of the application may need to be taken care of. For example, “Hello” is an english word. The same word may be written in different languages differently. The user-interface issues have similar problems. The strings written in different language require space differently and may create problems in appearance.
• #11: Using this slide, discuss the factors to be considered while developing international application. The faculty must use the previous slide to categorize the issues. Working with multiple culture codes can lead to formatting issues Culture-specific formatting Character encoding can lead to language issues Handling right-to-left display can lead to language issues, formatting issues, and user-interface issues Validating non-Latin user input can lead to language issues as well as string related issues Using the culture-specific classes and methods can lead to language issues
• #12: Reiterate the concepts taught earlier by asking the given question.
• #13: The faculty must demonstrate the creation of such applications. In addition, using this slide you can discuss globalization with the students. You can take the same example from the SG which is as follows: Consider a form with a Label control named DateLabel, whose Text property is set as: DateLabel.Text = “5/23/1994”; In this case, the Text property of the DateLabel control is set to a constant value and therefore, will always be displayed, as is, whatever be the current culture-settings. Different cultures may use different formats for displaying dates. Therefore, you need to set the Text property of the DateLabel in such a way that allows the application to automatically display the date in a format corresponding to the current culture settings. You can set the Text property of the label by using the Format function, as shown in the following example: DateTime MyDateTime = DateTime.Parse("May 23, 1994"); DateLabel.Text = (MyDateTime.ToString(“d”));
• #14: Using this and the next slide, the faculty must demonstrate how an application is localized and how resource files are created.
• #16: Explain the advantage of using resource assemblies. These are extremely helpful in large applications where a large number of resource files are created.
• #17: Reiterate the concepts taught earlier by asking the given question.
• #18: You can summarize the session by using the summary given in the slides. In addition, you can also ask students summarize what they have learnt in this session.
