So, I have Googled about and it seems that while making custom Pop up menus, if one wants to pass parameters then this is possible but for me comes with 2 major pro
You can use the .Parameter property. This is an example of a code in production (with only the lines of interest):
Dim i As Integer
Set cl = MainForm.Controls("classroomList")
For i = 0 To cl.ListCount - 1
With .Controls.Add(Type:=msoControlButton)
.Caption = cl.List(i)
.faceId = 177
.OnAction = "'" & ThisWorkbook.Name & "'!" & "assignClassroom"
.Parameter = cl.List(i)
End With
Next i
And the procedure could be something like:
Public Sub assignClassroom(Optional someArg as SomeType)
' code here
CommandBars.ActionControl.Parameter 'The parameter here
' more code here
End Sub
