Create a circle (oval) from the Drawing Toolbar. Format the autoshape
(right click) and set the font to Wingdings (and the size and boldness to
suit) and set the alignment to Center for both horizontal and vertical.

Paste this code into a standard module

Sub CheckCircle()

With Sheet1.Shapes(1).TextFrame
If .Characters.Text = Chr$(252) Then
.Characters.Text = ""
Else
.Characters.Text = Chr$(252)
End If
End With

End Sub

Right click on the autoshape and choose "assign macro" and assign
CheckCircle to it. Whenever you click the circle, a check mark should
appear and disappear alternately. You can also experiment with different
fonts and different numbers in the Chr$() function to find a check mark more
to your liking.

Hello, I have a user who is asking if it is possible to create a
custom checkbox control for use inside of Excel. This new checkbox
control is essentially a checkbox control that has other graphics
around the checkmark other than a square.

For instance, he need to have a triangle that has a clickable
checkmark inside it. He needs a circle with a clickable checkmark
inside as well as a couple of other shapes that have a clickable
checkmark inside (no square around the checkbox). I've tried to put
a regular checkbox on top of a graphic but you have to deal with the
square corners of the checkbox even if it's set to transparent.

Anyone seen any code or otherwise on how to create a custom or add-in
that would do what I describe?

Thanks
