Exception thrown by a driver when it receives an unknown command through the Action method.
An attribute for declaratively associating an assembly, class or property with an ASCOM device ID (and optionally, a display name).
Exception thrown by DriverAccess to return a driver COM error to the client. This exception appears as a COMException to the client having the original exception's description and error number as well as the original exception as the inner exception.
This is the generic driver exception. Drivers are permitted to directly throw this exception as well as any derived exceptions. Note that the Message property is a member of, the base class of DriverException. The property of is simply renamed to Number.
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.
Error numbers for use by drivers.
This exception should be raised by the driver to reject a command from the client.
Exception to report an invalid value supplied to a driver.
All methods defined by the relevant ASCOM standard interface must exist in each driver. However, those methods do not all have to be implemented. The minimum requirement for each defined method is to throw the ASCOM.MethodNotImplementedException. Note that no default constructor is supplied. Throwing this requires the the method name.
This exception should be raised when an operation is attempted that requires communication with the device, but the device is disconnected.
All properties and methods defined by the relevant ASCOM standard interface must exist in each driver. However, those properties and methods do not all have to be implemented. This exception is a base class for PropertyNotImplementedException and MethodNotImplementedException, which drivers should use for throwing the relevant exception(s). This class is intended to be used by clients who wish to catch either of the two specific exceptions in a single catch() clause.
This exception should be used to indicate that movement (or other invalid operation) was attempted while the device was in a parked state.
All properties defined by the relevant ASCOM standard interface must exist in each driver. However, those properties do not all have to be implemented. The minimum requirement for each defined property is to throw the ASCOM.PropertyNotImplementedException for each of its accessors. Note that no default constructor is supplied. Throwing this requires both the property name and unimplemented accessor type to be supplied.
An attribute that confers a 'friendly name' on a class and marks it as loadable by LocalServer. The 'friendly name' is used by the ASCOM LocalServer to register the class with the ASCOM Chooser. The 'friendly name' is what gets displayed to the user in the driver selection combo box. This attribute is also used by the LocalServer to filter the assemblies that it will attempt to load at runtime. LocalServer will only load classes bearing this attribute.
Provides settings storage for ASCOM device drivers. Settings are persisted in the ASCOM Device Profile store.
This exception should be used to indicate that movement (or other invalid operation) was attempted while the device was in slaved mode. This applies primarily to domes drivers.
Exception to report that no value has yet been set for this property.
