Answer / karthikeyan
SendMessage is a blocking call. ie., when a SendMessage()
API is called from an application, the lines written after
this API call cannot be executed until the message is
processed and returned by the window procedure.
Whereas PostMessage() just posts the message into the
windows corresponding message queue and returns immediately
irrespective of the message is processed or not.
