Here's another question I have seen a few times related to the RIBBONLib:
I have managed to make my controls/buttons call custom procedures in my MapBasic application using the RBNControlSetCustomMBXHandlerIdx procedure from the RIBBONLib.
But when I assign a standard menu ID to the control using the same procedure, nothing happens when I click the control in MapInfo Pro.
How should I assign a standard MapInfo Pro menu ID to my control?
