setPointLock
setPointLock — sets
the lock attributes of a Cascade DataHub point.
Syntax
For C++:
ST_STATUS setPointLock( | CDataHubPoint& | point, |
| | bool | locked); |
ST_STATUS setPointLock( | LPCTSTR | pointname, |
| | bool | locked); |
For Java:
Exception setPointLock( | DataHubPoint | point, |
| | boolean | locked); |
Exception setPointLock( | String | pointname, |
| | boolean | locked); |
For C#:
Exception setPointLock( | DataHubPoint | point, |
| | bool | locked); |
Exception setPointLock( | String | pointname, |
| | bool | locked); |
Parameters
- point
A
DataHubPoint object. The name
and security members must be valid.
- pointname
- locked
If
TRUE, the point will have its locked
attribute set, otherwise the locked attribute is
cleared.
Returns
For C++:
ST_OK if the command was
successfully sent to the DataHub. Since the command
is sent asynchronously, the actual success or failure of
the command must be determined through the onSuccess
or onError
message handlers.
ST_NO_TASK if a connection to
the DataHub does not exist.
ST_ERROR if the connection
socket is unable to send the message.
Description
This method sets the lock
attributes of a Cascade DataHub point.
