Errata for MCTS Self-Paced Training Kit (Exam 70-511): Windows® Application Development with Microsoft® .NET Framework 4

Practice test questions - Question ID 511P_1.2_07 The correct answer here is incorrectly displayed : panel1.Controls.Add(panel1, 1, 1); It should read: panel1.Controls.Add(button1, 1, 1); == Question ID 511P_3.2_01 The correct answer rendered by the test engine indicates A "TypeConverter" class should be used. However the comments indicate that the TypeConverter is incorrect in this instance and that an Implementation of IValueConverter should be used instead.

There is no valid answer to this question on the practice test: "You are implementing a Windows Forms application. A button named button1 should be added to the second column of the second row of a TableLayoutPanel named panel1. You need the button at run time. Which code segment do you add to your form?" The answer which we are told is correct is: panel1.Controls.Add(panel1, 1, 1) That should be: panel1.Controls.Add(button1, 2, 1) Because we are adding the button, not the panel, and rows start at 0 so the second row is 1 but columns start at one so the second column is 2.

Note from the Author or Editor:
Correct. Change as above.

HorizontalScrollBar should be HorizontalScrollBarVisibility in "You also can enable a horizontal scroll bar by setting the HorizontalScrollBar property, but this setting is less useful."

1. Get the AssemblyName object that represents the resource-only assembly, as shown here: Sample of Visual Basic Code Dim aName As System.Reflection.AssemblyName aName = System.Reflection.AssemblyName.GetAssemblyName("C:\myAssembly.dll")) Sample of C# Code System.Reflection.AssemblyName aName; aName = System.Reflection.AssemblyName.GetAssemblyName("C:\\myAssembly.dll")); Both of those have an extra closing parenthesis at the end!

Note from the Author or Editor:
Correct. Delete extra paraenthesis.

is: "public RoutedUICommand Launch" should be: "public static RoutedUICommand Launch"

Note from the Author or Editor:

In the description of NonZero, the last line is around the wrong way. It should be, "...the area is not filled. Otherwise, the area is filled."

Note from the Author or Editor:
Correct. Fix as above.

The AsciiOnly property, when set to True, does allow use of ASCII characters other than letters (i.e., numbers, punctuation, etc.) when the masking element of the Mask property is ampersand (&) or C. While this is also incorrect on the Microsoft page: http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.asciionly.aspx It is explained here: http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.mask.aspx

Note from the Author or Editor:
Correct. Update as above.

In the definition of the property MultColumn, it says "Indicates whther this item shows multiple columns of items or only a single item." I believe that should be "...only a single column."

Note from the Author or Editor:
Correct. Change single item to single column.

"Although multiple items can be selected, only one item can be selected in the CheckedListBox ****at any time.****" should say "at **a** time.***.

Note from the Author or Editor:
correct. change as above.

ToolStripMenuItem newMenuItem1; ToolStripMenuItem newMenuItem2; //Adds a new menu item by specifying text newMenuItem1 = MenuStrip1.Items.Add("File"); ***above line must cast MenuStrip1.Items.Add("File") to ToolStripMenuItem** ----- newMenuItem1 = (ToolStripMenuItem)MenuStrip1.Items.Add("File");------ Likewise //Adds a new menu item by specifying an image ***above line must cast MenuStrip1.Items.Add("File") to ToolStripMenuItem** ----- newMenuItem1 = (ToolStripMenuItem)MenuStrip1.Items.Add(anImage);------

Note from the Author or Editor:
Correct. Modify code sample as shown above.

At the start of Exercise 3 (In Ch4, Lesson 4), Step 1 instructs you to 'Open the partial solution for this exercise on the companion CD' but there is no such solution included on the disk. Exercise 3 is simply a continuation of exercises 1 and 2.

Note from the Author or Editor:
There should have been a partial solution included on disk, but an alternate solution is to simply continue with the finish of exercise 2.

"The MenuStrip control is the host for ToolStripMenuItem properties, which represent individual menu items." I think these are objects, not properties.

Note from the Author or Editor:
Correct. Change properties to objects.

The following * Dialog boxes are special forms that are designed to collect information from the user. Dialog boxes can be displayed either modally or modelessly. Modal dialog boxes halt program execution until the dialog box is closed, whereas modeless dialog boxes allow program execution to continue while they are displayed. * You can use the ShowDialog method to set the parent form of a dialog box. You can then retrieve information from the parent form by casting a reference to the parent form to the appropriate type. Should be located in the review for lesson two(2) and not lesson one(1).

Note from the Author or Editor:
Yes. Move to lesson 2.

The argument used in the PropertyChangedEventArgs in the Set Property for the Property Name should not be "LastName" but "Name". The class name is LastName, but the property is Name. (Actually it would make more sense if the class name were Name and the property LastName, but that's not what is written in the sample code.)

Note from the Author or Editor:
Correct

The code presented should close with <Window>, not </Window.Resources>.

Note from the Author or Editor:
Correct. Add <Window> to close the code.

In the description of the example for the HierarchicalDataTemplate XAML code, it states the interface contains a TreeView control, but then says the HierarchicalDataTemplate is applied to the "items displayed in ListView" and the ItemTemplate property is "applied to sub-items in Listview". There is no Listview in the example.

Note from the Author or Editor:
Change Listview to Treeview

The bolded attribute ... ItemTemplate="BasicTemplate" ...is incorrect. It should be: ItemTemplate="{StaticResource BasicTemplate}"

Note from the Author or Editor:
Correct. Change as indicated.

Correct-fix as above.
