Then open the code for Slide 1, and paste the attached code into the window, if the code is not there already. To try this macro out, download the PPTX (for PowerPoint 2007 and up) or PPT and then open up VBA (for example, in PowerPoint 2007, click the Developer tab on the ribbon, then select Visual Basic). Changes in this textbox are reflected on the 'bingo ball'. The textbox is included for authenticity, as it allows the user to change the letter on the 'bingo ball'.

Once all the possible numbers have been used, the macro disables the button to generate the next number and forces the user to press the reset button to continue. The generated numbers can be reset by clicking the asterisk button on the slide as the 'game' is running. The macro also stores a list of the generated numbers ( PickedNumbers private integer array) and checks to see if a newly generated number has already been selected and used. The lower and upper limits can be changed by setting the constants SMALLEST_NUMBER and BIGGEST_NUMBER, respectively, in the declarations area of the code. This code generates pseudo-random numbers between 1 and 75. This macro demonstrates the power of Visual Basic for Applications (VBA) in PowerPoint to obtain data from, and make dynamic changes to, elements of a slideshow at runtime. We used this as a youth group activity but it could be adapted for other entertainment or competition purposes as well. The code checks the generated numbers against a list of numbers already generated to prevent duplication.
