Microsoft TS: Microsoft .NET Framework 2.0 - Web-based Client Development : 070-528

You are developing a Web application. The Web application uses the following code segment to connect to
a database.
conn.ConnectionString = "Server=(local); " & _
"Initial Catalog=NorthWind;Integrated Security=SSPI;"
You create logins in Microsoft SQL Server for each user of the Web application. When you run the Web
application, you receive the following error message.
"Login failed for user 'COMPUTERNAME\ASPNET'."
You need to resolve this error.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. In the Web.config file, set the authentication mode to Windows.
• B. In the Web.config file, enable impersonation.
• C. In the Web.config file, disable impersonation.
• D. In IIS, deny anonymous access.
• E. In IIS, allow anonymous access.

You are developing a Microsoft ASP.NET application.
You add a templated Web user control to a Web Form by using the following code fragment.
<uc1:MyControl ID="MyControl1" runat="server">
<HeaderTemplate>
<asp:Label ID="HeaderLabel" runat="server" />
</HeaderTemplate>
<BodyTemplate>
<asp:TextBox ID="TemplateTextBox" runat="server" />
</BodyTemplate>
</uc1:MyControl>
You write the following code segment in the Web Form's code-behind file. (Line numbers are included for reference only.)
02 protected void Page_Load(object sender, EventArgs e) { 04 }
You need to modify the Visible property of the TemplateTextBox control from the Web Form's code-behind file as false.
What should you do?

• A. Insert the following line of code at line 01. protected TextBox TemplateTextBox = null; Insert the following code segment at line 03. EnsureChildControls(); TemplateTextBox.Visible = false;
• B. Insert the following code segment at line 03. TextBox templateTextBox = (TextBox)MyControl1.FindControl("TemplateTextBox"); templateTextBox.Visible = false;
• C. Insert the following code segment at line 03. TextBox templateTextBox =(TextBox)MyControl1.FindControl("BodyTemplate/TemplateTextBox"); templateTextBox.Visible = false;
• D. Insert the following line of code at line 01. protected TextBox TemplateTextBox = new TextBox(); Insert the following line of code at line 03. TemplateTextBox.Visible = false;

You are creating a DataTable. You use the following code segment to create the DataTable. (Line numbers are included for reference only.)
01 DataTable dt = new DataTable("Products"); 02 dt.Columns.Add(new DataColumn("Price", typeof(decimal))); 03 dt.Columns.Add(new DataColumn("Quantity", typeof(Int32))); 04 DataColumn dc = new DataColumn("Total", typeof(decimal)); 05 dt.Columns.Add(dc);
You need to ensure that the Total column is set to the value of the Price column multiplied by the Quantity column when new rows are added or changed.
What should you do?

• A. Add the following code segment after line 05. dc.ExtendedProperties["Total"] = "Price * Quantity";
• B. Write an event handler for the DataTable's TableNewRow event that updates the row's Total.
• C. Add the following code segment after line 05. dc.Expression = "Price * Quantity";
• D. Write an event handler for the DataTable's ColumnChanged event that updates the row's Total.

You are creating a Microsoft ASP.NET Web application that uses Web Parts.
You need to ensure that users can modify the properties of Web Part controls. You also need to ensure that modifications are persisted.
What should you do?

• A. *Apply the [Personalizable(false)] and [WebBrowsable(false)] attributes to the public properties of the control. Add the following code fragment to the Web page. <asp:EditorZone ID="EditorZone1" runat="server"> <ZoneTemplate> <asp:BehaviorEditorPart ID="EditorPart1" runat="server" /> </ZoneTemplate> </asp:EditorZone>
• B. *Apply the [Personalizable(true)] and [WebBrowsable(true)] attributes to the public properties of the control. Add the following code fragment to the Web page. <asp:EditorZone ID="EditorZone1" runat="server"> <ZoneTemplate> <asp:BehaviorEditorPart ID="EditorPart1" runat="server" /> </ZoneTemplate> </asp:EditorZone>
• C. *Apply the [Personalizable(true)] and [WebBrowsable(true)] attributes to the public properties of the control. Add the following code fragment to the Web page. <asp:EditorZone ID="EditorZone1" runat="server"> <ZoneTemplate> <asp:PropertyGridEditorPart ID="EditorPart1" runat="server" /> </ZoneTemplate> </asp:EditorZone>
• D. *Apply the [Personalizable(false)] and [WebBrowsable(false)] attributes to the public properties of the control.
  Add the following code fragment to the Web page.
  <asp:EditorZone ID="EditorZone1" runat="server">
  <ZoneTemplate>
  <asp:PropertyGridEditorPart ID="EditorPart1" runat="server" /> </ZoneTemplate>
  </asp:EditorZone>

You are creating a templated Web control for use in your Web application.
You need to add the Web control to your Web application pages without compiling your control into a .dll file.
What should you do?

• A. Ensure that the Web control inherits from the WebControl class.
• B. Ensure that the Web control inherits from the UserControl class.
• C. Ensure that the Web control inherits from the Control class.
• D. Ensure that the Web control inherits from the CompositeControl class.
