Assume certain facts. Points is the name of an int variable, and TextBox is the name of a TextBox control. Create an if-else statement that converts the Text property of the pointsTextBox control to an int and saves the result in the points variable using one of the TryParse methods. If the conversion fails, a message box will appear with an error message.

Given the following statement: boolean exp = ( ( boolean1 || ( ! boolean2 ) ) && boolean3 ); Retype it in the input textbox below and remove as many parenthesis as possible without changing how the expression is evaluated. Without changing how the expression is evaluated means that the operators are evaluated in the same order in your answer and the original expression.

assumes that points is an int variable and that TextBox is a TextBox widget. Put the result in the points variable after converting the Text property of the points TextBox control to an int. Display an error message in a message box if anything goes wrong.

Assume certain things to be true. points is the name of a variable that stores integer values, while textbox is the name of a textbox control. Implement the TryParse methods in an if-else statement that transforms the Text property of a pointsTextBox control to an int and stores the result in a points variable, as shown in the following example. If the conversion fails, an error message will be shown in a message box on the screen.

Write an assignment statement that increments the intTotal variable by the contents of the intQuantity variable.

Can I simultaneously choose several CheckBox controls from inside a single GroupBox? Do you think that is true or false?

Using C# in a visual studio form, Create an application. Add a label and a button to the form. The button’s Click event procedure should add the number 1 to the contents of a class-level Integer variable named intNumber and then display the variable’s contents in the label. Code the application. Be sure to enter the three Option statements above the Public Class clause. Save the solution and then start and test the application. Next, change the class-level variable to a static variable.
