Excel double click on a ribbon button to initiate macro

Question

I have a seemingly simple problem in Excel 2013 to which I cannot find an answer. Below I described all the details. Big thanks in advance for any help.

Circumstances surrounding the problem:

1. I made a "QuickMacro.xlsm" workbook in Excel that contains Macro1.
2. Secondly I added custom ribbon (through excel tools, not in VSTO) and on that ribbon I added said macro.
3. Now every time I open an excel workbook I have a quick accces to that macro across all workbooks on my computer (and the workbook with said macro is hidden, so I do not see it and it does not interfere with my work)

My problem: I want Macro1 to initiate only when I double click its icon on the ribbon. Single click ought to do nothing.

My research on the problem: To find an answer I have went through many msdn materials on VSTO add ins and macros tutorials. The problem with former is that I am only a beginner in VSTO, and with latter that I find only "Worksheet_BeforeDoubleClick" events that regard cell activation, not ribbon button activation.

Question: Finally, my question is: how can it be done? Is there a way to do it with Excel only or do I need to start learning advanced VSTO? Also, I would also appreciate any general tips on where to start digging to solve this problem (except msdn sites which I have analyzed extensively). Any books maybe?

Answer 1

Tested by assigning this to a shape on a worksheet (so your Sub declaration may look different).

Sub MenuAction()

    Static t As Double

    '0.25 sec double-click interval
    If [NOW()] - t > (1 / 24 / 60 / 60 / 4) Then
        t = [NOW()]
        Exit Sub
    End If

    Debug.Print "double-click"
    'run your code here

End Sub

EDIT: a side note on use of [NOW()] vs. Now() . I saw a post saying that these two expressions have different precision and that [NOW()] is more precise.

For example (also included Time for comparison):

Sub Tester() Dim i, x

For i = 1 To 10
    'make a delay...
    For x = 1 To 3000#
        DoEvents
    Next x
    Debug.Print Time * 1, Now() * 1, [NOW()] * 1
Next i

End Sub

Output:

 Time                        Now()                       [NOW()]
