This exception should only be thrown if there is no other more appropriate exception already defined, e.g. PropertyNotImplemented, InvalidOperationException, InvalidValueException, NotConnectedException etc. These specific exceptions should be thrown where appropriate rather than using the more generic DriverException. Conform will not accept DriverExceptions where more appropriate exceptions are already defined.
As good programming practice, the Message property should not be empty, so that users understand why the exception was thrown.
Thetype exposes the following members.
Initializes a new instance of the UnspecifiedError.class that will return the 'unspecified error' number: 0x800404FF. Sets the COM HResult to
Initializes a new instance of theclass with a human-readable descriptive message.
Initializes a new instance of theclass from another caught exception and a human-readable descriptinve message.
Create a new ASCOM exception using the specified text message and error code.
|DriverException(String, Int32, Exception)|
Create a new ASCOM exception based on another exception plus additional descriptive text and error code. This member is required for a well-behaved exception class. For example, if a driver receives an exception (perhaps a COMException) from some other component yet it wants to report some meaningful error that resulted from the other error, it can package the original error in the InnerException member of the exception it generates.
