This is a program that simulates a lucky draw game. This program consists of a 3x3 matrix, which means there are 9 command buttons in a grid. The command buttons are created as controls in an array, and they are differentiated by their indices. One of the button contains a prize, when you click on it, it displays the word "prize" on the caption. If you do not strike the prize , the word "The Prize is here! " will appear on the command button that contains the prize.
We use a randomize process and the indices of the command buttons to create the chance events. Random integers from 1 to 9 can be created using the statement n=Int(Rnd*9) where Int is a function that converts numbers to integers and Rnd is a method hat generates random numbers between 0 and 1. When the user click a command button, a random number between 0 and 9 is generated and if this number corresponds to the index of the command button, it will show the word "Prize" on the clicked command button , otherwise, it shows the words "The Prize is here!" on the command button with an index corresponds to the generated number.
