Excel Ribbon: Use one custom ribbon button to enable all other custom ribbon buttons

Question

This is based on Ron de Bruin's code "Enable or Disable custom ribbon buttons".

The following example ribbon consists of two tabs:

• 'Tools': empty for now
• 'Macros': 3 groups

All buttons are built with tag and getEnabled. So by default 'Group6' and 'Group7' are disabled, 'Group8' with 'Button57' is enabled. I’d like to enable 'Group6' and 'Group7' with 'Button57' (password protected).

Running the macro EnableAllControls by pressing play in the VBA editor works as expected.

But using Call does not work:

'Callback for Button57 onAction
Sub c001_01_EnableTabMacros(control As IRibbonControl)
    Call EnableAllControls
End Sub

How do you Call EnableAllControls?

Answer 1

Through some trial and elimination, it appears that because the callback sub's name starts with the letter c as in c001_01_EnableTabMacros the compiler is not able to see that name. Changing the leading c to another, say d, it does work.
