Readiness review question has two correct answers
On the Readiness Review assessment, one of the questions has two correct answers, but only one is marked correct.



The question begins:

"You are creating a Windows Forms application. An application form executes a long-running method named CalculateExponentialMovingAverage by creating an instance of the delegate that refers to the method implementation and calling the method's BeginInvoke method."



One of the answers is marked incorrect, but it is correct. The answer reads:

"Call the delegate's EndInvoke method."

Incorrect answer marked correct in Readiness Review
On the Readiness Review assessment, one of the questions has an incorrect answer marked correct.



The question reads:

"Your application includes an instance named configuration of the following class:



public class ApplicationConfiguration : INotifyPropertyChanged

{

public bool ShowDebug

{

set { ... }

get { ... }

}

...

}



You need to add code to your form to use databinding to show a Button control named debugButton if the ShowDebug property is true and to hide the button if it is not.



Which code segment should you use?"



This question marks two answers as correct, when there is only one correct answer. The incorrect answer that is marked correct reads:

this.debugButton.DataBindings.Add("Text", configuration, "ShowDebug");

The question reads:
"You need to add a button named button1 to a TableLayoutPanel named panel1 at run time. You want to add button1 to the second column of the second row.

Which code segment do you add to your form?"

The answer marked correct reads:

panel1.Controls.Add(panel1, 1, 1);

It should read:
panel1.Controls.Add(button1, 1, 1);

The question reads:
"You are reviewing the design of a Windows Forms application that will execute from a partially trusted environment. You must identify any task that will not be allowed with the default permission set granted for an application in the Local Intranet zone.

Which task should you identify?"

The answer that should be marked correct reads:

"Call unmanaged code"

The questions reads:

"Which of the following values for the Zoom property will cause the document to be previewed at 250 percent of normal size?"

The correct answer should be:
2.5

SizeType.Absolute should be SizeType.AutoSize
On page 29, the first sentence of the last paragraph refers to an incorrect SizeType.



Change:

"If you set a row or column style to a size type of anything other than SizeType.Absolute, you can also set the Width (for columns) or Height (for rows)."



To:

"If you set a row or column style to a size type of anything other than SizeType.AutoSize, you can also set the Width (for columns) or Height (for rows)."

Change:
"Columns in a TableLayoutPanel are numbers starting at 1, while rows start at 0."

To:
"Columns and rows in a TableLayoutPanel are numbers starting at 0."

"SplitContainter" should be "SplitContainer"
On page 32, the 3rd sentence in the second paragraph contains a misspelled control.



Change:

"Note that a panel is fixed by the FixedPanel property only when the SplitContainter control is resized."



To:

"Note that a panel is fixed by the FixedPanel property only when the SplitContainer control is resized."

"BorderStyle" should be "FormBorderStyle"

property should be control
On page 50, the last sentence of the second paragraph is incorrect.



Change:

"The property will relocate to the new location."



To:

"The control will relocate to the new location."

The last sentence of the "," section is missing a comma. "0," should be "0,,"

"TabContainer" should be "TabControl"
On page 699, the first sentence of Case Scenario 2 contains an incorrect control.



Change:

"You can use the TabContainer control to display multiple pages of information and allow the user to switch between pages while keeping the information static."



To:

"You can use the TabControl control to display multiple pages of information and allow the user to switch between pages while keeping the information static."
