title: c# Excel Application.EnableEvents
body: <p>I have to create an Excel-COM-Add-In, that validate some values of several cells. Normally this requirement is easy to realise, but in the actual case there is installed another COM-Add-IN, which set the flag for the "Application.EnableEvents" to false. The result is, that no event will be fired at runtime. My question is: "How can I recognize if the flag was set by the COM-ADD-In at runtime?" or "Is it possible to create an eventhandler to monitoring this flag?"</p>
  
  <p>Thanks for your response!</p>
