Open the VB2015\Chap08\Color Solution\Color Solution (Color Solution.sln) file. The btnDisplay_Click procedure should display the color of the item whose item number is entered by the user. All item numbers contain exactly five characters. All items are available in four colors: blue, green, red, and white. The third character in the item number indicates the item’s color, as follows: a B or b indicates Blue, a G or g indicates Green, an R or r indicates Red, and a W or w indicates White. The procedure should display an appropriate error message if the item number does not contain exactly five characters, or if the third character is not one of the valid color characters. Test the application appropriately.
