My question here is when the round green button is activated, I can not change the values of the combo string or Vname or Iname even these control are enabled. Anyone has idea why this happen and how I can change the values of these controls?
As I said above, they are never enabled using your code.
Quote from my earlier post (highlight added):
"Your "disabled" property is either 1 (disabled), or 2 (disabled&grayed out), never zero (enabled). Unless it is enabled, you cannot operate it!"
