c# - Using ReactiveUI InvokeCommand Extension with Changing Targets -

-

The code below works, I do not know that this is the best practice, I am thinking that I am more on the situation I am thinking.

Status: The code below is in my main view model manufacturer. ViewModel has MessageHandler which has Reactive Commands property on which it is called Receivemessage . ViewModel has a property with a RawMessage with another property ScannerViewModel . I would like to use the Reactive UI code. Invoic Commands () Extension Method for Pipe RawMessage to Receivemessage I want it to check for .CENExecute Although MessageHandler (or even getmessage potentially possible) may change, as well as with ScannerViewModel . 

  this.WhenAnyValue (t = & gt; t.MessageHandler.ReceiveMessage). Select (CMD => this when any value (T => TSCNR Videodel.Romesses). Invoke Commands (CMD). Scan (Disposable.pt, (ACC, N) => ACC. Dies (); Return n;}). Subscribe ();

then seems to work up. I am not sure whether I need to dispose of the last incocommand disposation, so that the .can section may be unnecessary or may have done better.

I tried to overload the Awake Commands extension, which could set you a goal, but it seemed static, or I understood the syntax to move it Could not be a inspector as a goal: 

  this.WhenAnyValue (t => t.ScannerViewModel.RawMessage). InvoCommand (MessageHandler, m => m.receiveMessage);

This will follow RawMessage as its parent, but if MessageHandler is changed then it will be broken and it does not compile Is: 

  this.WhenAnyValue (t = & gt; t.ScannerViewModel.RawMessage). InvoCommand (this.WhenAnyValue (t => T. MessageHandler), M => m.ReceiveMessage);

I am not against anything that I have found, unless it finds any fault with it. I'm looking for something that is probably less pronounced and easy to follow.

Do not ask me why do not I think: 

  this WhenAnyValue (t = & gt; t.ScannerViewModel.RawMessage). InvoCommand (this, t => T. Message Handler. Receive Message);

I was looking at it upside down I think it will receive what I want.

From time to time, I have to make the framework that I have already found solutions to problems - it is only a case of messing up for yourself.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
