You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Assigning macros to shapes
Perhaps the most remarkable thing that you can do with shapes is get them to run macros:
We'll arrange it so that when you click on the shape, you'll see a message box appear!
Here's the message that clicking on the owl will show:
The message our macro will show.
To make this work you need to create a macro first, then assign it to a shape.
Creating the macro
Here's a modest macro which displays the hoot message on screen (and reads it out for good measure, although it sounds a bit strange!):
'make the owl hoot!
MsgBox "Tu-whit, tu-whoo"
'just in case you missed it, say it out loud
Application.Speech.Speak "Tu-whit, tu-whoo"
The macro you create must be contained in the same workbook as the shape.
Assigning a macro to a shape
To do this, set the shape's OnAction property:
'text box and owl logo, plus connector
Dim Logo As Shape
'set reference to a worksheet
Set w = ActiveSheet
'now add the owl logo (initially a rectangle)
Set Logo = w.Shapes.AddShape(1, 10, 10, 50, 50)
Logo.Fill.UserPicture "C:\ajb files\wise-owl-logo.jpg"
'assign a macro to it
Logo.OnAction = "Hoot"
That's all that you need to do! Clicking on the shape will now run the Hoot macro.
As a postscript to this blog, I've included some links to some online exercises, so that you can test your VBA ability!
