2. You write a Web application. This application must support multiple languages. You store the localized strings in the application as resources. You want these resources to be accessed according to a user's language preference. You create the following resource files in the App_GlobalResources folder of your application.
myStrings.resx
myStrings.en-CA.resx
myString.en-US.resx
myStrings.fr-CA.resx
myStrings.es-MX.resx
Each resource file stores a localized version of the following strings: Name, E-mail, Address, and Phone. You create a Web Form that contains one label for each of these strings.
You need to ensure that the correct localized version of each string is displayed in each label, according to a user's language preference.
What should you do?
A. Add the following configuration section to the Web.config file.
<globalization culture="Auto" />
B. Set the directive for each page in your site as follows:
<%@ Page UICulture="Auto" ... %>
C. Add the following code segment to the page's load event.
lblName.Text = @"{myStrings}Name";
lblAddress.Text = @"{myStrings}Address";
lblEmail.Text = @"{myStrings}Email";
lblPhone.Text = @"{myStrings}Phone";
D. Add the following code segment to the page's load event.
lblName.Text = Resources.myStrings.Name;
lblAddress.Text = Resources.myStrings.Address;
lblEmail.Text = Resources.myStrings.Email;
lblPhone.Text = Resources.myStrings.Phone;
Answer: D

3. Your Web site uses custom Themes. Your Web site must support additional Themes based on the user's company name.
The company name is set when a user logs on to the Web site. The company's Theme name is stored in a variable named ThemeName.
You need to use this variable to dynamically set the Web site's Theme.
What should you do?
A. Add the following code segment to the markup source of each page on the Web site.
<%@ Page Theme="ThemeName" ... %>
B. Add the following code segment to the Load event of each page on the Web site.
Page.Theme = ThemeName;
C. Add the following code segment to the PreInit event of each page on the Web site.
Page.Theme = ThemeName;
D. Add the following code segment to the Web site's configuration file.

4. You create a Web Form. The Web Form uses the FormView control to enable a user to edit a record in the database.
When the user clicks the Update button on the FormView control, the application must validate that the user has entered data in all of the fields.
You need to ensure that the Web Form does not update if the user has not entered data in all of the fields.
Which code segment should you use?
A. protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) {
foreach (DictionaryEntry entry in e.Keys) {
if (entry.Value.ToString() == System.String.Empty) {
e.Cancel = true;
return;
}
}
}
B. protected void FormView1_ItemUpdated(object sender, FormViewUpdatedEventArgs e) {
foreach (DictionaryEntry entry in e.NewValues) {
if (entry.Value.Equals("")) {
e.KeepInEditMode = true;
return;
}
}
}
C. protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) {
foreach (DictionaryEntry entry in e.NewValues) {
if (entry.Value.Equals("")) {
e.Cancel = true;
return;
}
}
}
D. protected void FormView1_ItemUpdated(object sender, FormViewUpdatedEventArgs e) {
foreach (DictionaryEntry entry in e.Keys) {
if (entry.Value.ToString() == System.String.Empty) {
e.KeepInEditMode = true;
return;
}
}
}
Answer: C

5. You create a Web Form. The Web Form allows users to calculate values and display the results in a label named lblResults.
You need to capture all unhandled exceptions on the Web Form through the Error event. The Error event must capture each unhandled exception and display it on the Web Form.
Which code segment should you use?
A. protected void Page_Error(object sender, EventArgs e) {
lblResults.Text = e.ToString();
e=null;
}
B. protected void Page_Error(object sender, EventArgs e) {
lblResults.Text = Server.GetLastError().ToString();
Server.ClearError();
}
C. protected void Page_Error(object sender, EventArgs e) {
Response.Write(e.ToString());
e=null;
}
D. protected void Page_Error(object sender, EventArgs e) {
Response.Write(Server.GetLastError().ToString());
Server.ClearError();
}
