Do you want a random number generator for your PowerPoint slide? Do you want some numbers from a chosen sequence of numbers to pop up every time you click? Yes, you can do this in PowerPoint using some simple VBA code, as Steve Rindsberg of PowerPoint FAQ explains.
First you need to know how you can run VBA scripts in PowerPoint -- then use this code. Explore the code a bit though since Steve has put in some helpful comments so that you can edit some values as required.
Sub UpdateRandomNumber(oSh As Shape) Dim X as Long 'Make the shape’s text a random number 'X or less 'Change 12 below to any number you’d like: X = 12 oSh.TextFrame.TextRange.Text = CStr(Random(X)) 'Now force PPT to go to the slide again (ie, to redraw it) so that 'the changed text appears: SlideShowWindows(1).View.GotoSlide (SlideShowWindows(1).View.Slide.SlideIndex) End Sub Function Random(High As Long) As Long 'Generates a random number less than or equal to 'the value passed in High Randomize Random = Int((High * Rnd) + 1) End Function
Once you have placed this code in the VBA editor, close the window to get back to your PowerPoint slides. Before you proceed further, it's a great idea to save your file -- be sure to save as a PowerPoint Macro-Enabled Presentation with the PPTM file extension or PowerPoint Macro-Enabled Show with the PPSM extension. If you save as any of the other file formats, PowerPoint will offer to remove the macros, and then of course the Random Number Generator will not work! See our PowerPoint File Formats page to learn about these file formats.
Select any text object such as a text box or even a shape that can fit in a number. Select the text object and format it so that it uses a font size and typeface that you want -- you can make these choices even though there's no actual text in the text object yet.
Now select the text object, and access the Insert tab of the Ribbon. Click the Action button to bring up the Action Settings dialog box. Make sure you are in the Mouse Click tab of this dialog box -- now select the Run Macro radio button, and choose the UpdateRandomNumber macro. Click OK, and you are done.
Run the slide in Slide Show view, and click the text object to see a random number.
Thank you so much, Steve.
We tested this code using PowerPoint 2010 for Windows.
