How can I push an object into an array?
You have to create an object. Assign the values to the object. Then push it into the array: var nietos = []; var obj = {}; obj[“01”] = nieto.label; obj[“02”] = nieto.value; nietos.push(obj);

After digging around I need to use trackBy on ngFor. Updated plnkr and code below. Working Plnkr @Component({ selector: ‘my-app’, template: ` <div> <div *ngFor=”let item of toDos;let index = index;trackBy:trackByIndex;”> <input [(ngModel)]=”toDos[index]” placeholder=”item”> </div> Below Should be binded to above input box <div *ngFor=”let item of toDos”> <label>{{item}}</label> </div> </div> `, directives: [MdButton, MdInput] …
Only instance members of the components class can be called from the view. If you want to call static members, you need to provide a getter in the component. export class MyComponent { parseDate = DateService.parseDate; } then you can use it like (input)=”event.date=parseDate($event.target.value)”
SQL Server only stores time to approximately 1/300th of a second. These always fall on the 0, 3 and 7 milliseconds. E.g. counting up from 0 in the smallest increment: 00:00:00.000 00:00:00.003 00:00:00.007 00:00:00.010 00:00:00.013 … If you need that millisecond accuracy, there’s no pleasant way around it. The best options I’ve seen are to …
In your current code, the perceptron successfully learns the direction of the decision boundary BUT is unable to translate it. y y ^ ^ | – + \\ + | – \\ + + | – +\\ + + | – \\ + + + | – – \\ + | – – \\ + …
Wrap BEGIN \ END statements around your bulk inserts. Sqlite is optimized for transactions. dbcon = new SQLiteConnection(connectionString); dbcon.Open(); SQLiteCommand sqlComm; sqlComm = new SQLiteCommand(“begin”, dbcon); sqlComm.ExecuteNonQuery(); //—INSIDE LOOP sqlComm = new SQLiteCommand(sqlQuery, dbcon); nRowUpdatedCount = sqlComm.ExecuteNonQuery(); //—END LOOP sqlComm = new SQLiteCommand(“end”, dbcon); sqlComm.ExecuteNonQuery(); dbcon.close();
One of the best examples of a practical use of a named pipe… From http://en.wikipedia.org/wiki/Netcat: Another useful behavior is using netcat as a proxy. Both ports and hosts can be redirected. Look at this example: nc -l 12345 | nc www.google.com 80 Port 12345 represents the request. This starts a nc server on port 12345 …

As of modern version of Excel, there’s the syntax with commas, not semicolons. I’m posting this answer for convenience of others so they don’t have to replace the strings- We’re all lazy… hrmp… human, right? =CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),”-“,DEC2HEX(RANDBETWEEN(0,65535),4),”-“,DEC2HEX(RANDBETWEEN(0,65535),4),”-“,DEC2HEX(RANDBETWEEN(0,65535),4),”-“,DEC2HEX(RANDBETWEEN(0,4294967295),8),DEC2HEX(RANDBETWEEN(0,65535),4)) Or, if you like me dislike when a guid screams and shouts and you, we can go lower-cased like …
As the others stated bool? is not equal to bool. bool? can also be null, see Nullable<t> (msdn). If you know what the null state wants to imply, you easily can use the ?? – null-coalescing operator (msdn) to convert your bool? to bool without any side effects (Exception). Example: //Let´s say “chkDisplay.IsChecked = null” …
