Initializes a new instance of the TwainException class with a specified error message, its Code set to TwainExceptionCode.NotInitialized and a reference to the inner exception that is the cause of this exception.
The error message that explains the reason for the exception.
The exception that is the cause of the current exception. If the innerException parameter is not a null reference (Nothing in VB), the current exception is raised in a catch block that handles the inner exception.
An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or a null reference (Nothing in VB) if the InnerException property does not supply the inner exception value to the constructor.
