Question

Write a Visual C# program that will input the user's name and a message. The user will be able to choose from an option of formatting tools to change the way the message (and only the message) will look. The user can choose from bold, underline, italic, along with several different color options. All changes the user selects will be displayed in the message textbox.

Once the user selects the Finish button, the two pieces of information entered by the user will be concatenated and added to the "previous messages" listbox or a textbox (you decide). The previous listbox/textbox will display all the concatenated messages entered by users along with their formatting changes.

For example: if the user enters "Suzie Student" as the name and the message "I like programming!" and changes the font color to Orange with Bold and Underline selected, the message should look like this: "I like programming!"   When the user clicks the Finish button, the previous listbox/textbox should display:

Suzie Student: I like programming!

It is an error if the user does not enter a name and/or a message and clicks the Finish button. You may want to consider disabling the Finish button until content is typed in both textboxes.

If the user enters a name and message and does not choose any color or formatting options and presses the Finish button, the name and message should be concatenated as is.

When the user selects the Clear button, the previous user's name and message will be cleared from their respective textboxes, but not the listbox. The next user is now ready to enter their name and message.

Find a logo image to add to the form. Every time the user clicks on the logo image, toggle the image to either large and small versions of the image OR to a different image of a similar nature.
