CCmdTarget::IsResultExpected

This method determines whether a client expects a return value from its call to an Automation method. The COM interface supplies information to MFC about whether the client is using or ignoring the result of a method call, and MFC in turn uses this information to determine the result of a call to IsResultExpected. If production of a return value is time- or resource-intensive, you can increase efficiency by calling this method before computing the return value.
