Question 1. Locate an animated .tif file on the Web. Create a project named Animated with a Form that contains a PictureBox. Display three different messages on a Label-one when the user's mouse is over the PictureBox, one when the mouse is not over the PictureBox, and one when the user clicks the PictureBox.

Question 2. Emma's Custom Embroidery sells shirts with detailed embroidered images. Emma allows users to select the color for a shirt, but she allows only specific embroidery designs with each shirt color. Create a project named EmmasEmbroidery that allows a user to choose one of four shirt colors from a ListBox-white, black, red, or blue. When the user selects a shirt color, the program should display a second ListBox that contains the following embroidery design choices:

- White shirt-peacock, palm tree, or rose
- Black shirt-race car, star, or moon
- Red shirt-palm tree or moon
- Blue shirt-peacock or moon

After the user selects an embroidery design, the program should display a congratulatory message on a Label indicating that the choice is a good one, and the design ListBox also becomes invisible. If the user makes a new selection from the shirt color ListBox, the congratulatory message is invisible until the user selects a complementary design.

Hint: You can remove the entire contents of a ListBox using the Items.Clear() method, as in this.listBox1.Items.Clear();.

Question 3. Create a project named GuessANumber with a Form that contains a guessing game with five RadioButtons numbered 1 through 5. Randomly choose one of the RadioButtons as the winning button. When the user clicks a RadioButton, display a message indicating whether the user is right.

Add a Label to the Form that provides a hint. When the user's mouse hovers over the label, notify the user of one RadioButton that is incorrect. After the user makes a selection, disable all the RadioButtons.

Question 4. Create a project named PickLarger with a Form that contains two randomly generated arrays, each containing 100 numbers. Include two Buttons labeled "1" and "2". Starting with position 0 in each array, ask the user to guess which of the two arrays contains the higher number and to click one of the two buttons to indicate the guess. After each button click, the program displays the values of the two compared numbers, as well as running counts of the number of correct and incorrect guesses. After the user makes a guess, disable the Buttons while the user views the results. After clicking a Next Button, the user can make another guess using the next two array values. If the user makes more than 100 guesses, the program should reset the array subscript to 0 so the comparisons start over, but continue to keep a running score.
