Programming Windows Applications: C#

All files within a windows desktop application are contained within a:

• Form
• Project
• Text Box
• Window

The following code will:
string name = "Jane";
lblDisplay.Text = name;

• Display "name" in the label lblDisplay
• Display "name" a MessageBox
• Display "Jane" in the label lblDisplay
• Display "Text" in the label name

The following code segment will:
MessageBox.Show("1 + 1" + " = 2");

• Display :1 + 1 + = 2
• = 2
• 1 + 1
• 1 + 1 = 2

To change the physical appearance of a form in Visual Studio you need to configure its:

• Toolbox
• Properties
• Project
• IDE

What is wrong with the following code segment:
int number = 5
MessageBox.Show("Number = " + number);

• number should use a decimal data type
• The first statement is missing a semicolon
• A label should have been used instead of a Messagebox
• number should be declared as a string

What will be the output of the following code segment:
int a = 3;
int b = 9;
int c = 0;
c = (a * b) + b
MessageBox.Show("Output = " + c);

• 27
• 21
• 0
• 36

An integer data type stores:

• Whole number values
• Decimal value
• Floating point values
• Text values

The following code segment will:
int Age;
Age = int.Parse(txtAge.Text);

• Pass the Age value to a new location
• Assign a text value to Age
• Convert number in text format  to integer form
• Calculate Age in minutes

The naming convention for button is:

• btnName
• txtName
• lblName
• frmName

The following code will:
string name = "Jane";
lblDisplay.Text = name;

• Display "name" in the label lblDisplay
• Display "name" a MessageBox
• Display "Jane" in the label lblDisplay
• Display "Text" in the label name
