Create a Windows application that contains two textboxes and two buttons. The
textboxes should be used to allow the user to input two positive numeric values.
The buttons should be labeled Add and Multiply. Create event-handler methods
that retrieve the values, perform the calculations, and display the result of the
calculations on a label. The result label should initially be set to be invisible with a
font color of yellow. If invalid data is entered, change the font color to red on the
result label and display a message saying ‘‘Value must be numeric and > 0.’’
When the final answer is displayed, the font color should be yellow. Additional
labels will be needed for the textboxes captions. Do not allow non-numeric
characters to be entered. Invoke the TryParse( ) method to retrieve the
values. All controls involved in program statements should be named. Right
justify values in the textbox.
