 Definitions of "primitive", "value type", "struct", "class", "wrap" in

With these it helps The first bullet point is correct. The second is not: the primitive types in .NET are Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, UIntPtr, Char, Double, and Single. A struct cannot usually be set to null, but there are also nullable value types (Nullable ). These are still value types, but there's syntactic sugar in C# to equate "null" with "the null value for the type", which for a nullable value type is an instance where HasValue returns false.

 How to implement the "Edit" menu with "Undo", "Cut", "Paste" and "Copy"
By : sammike

will be helpful for those in need It's easy enough to accomplish half of the necessary functionality. Just create the Edit menu, along with the necessary QActions (copy/paste/undo/etc.) in your main window class and connect them to slots. In the slots, emulate the correct key press and release events (e.g. Ctrl+C for Copy) and send them to the currently focused widget. In code, something like this: code :
MainWindow::MainWindow(...)
{
...
connect( actionCopy, SIGNAL( triggered()), SLOT( copy()));
...
}
...
void MainWindow::copy()
{
QWidget* focused = QApplication::focusWidget();
if( focused != 0 )
{
QApplication::postEvent( focused,
new QKeyEvent( QEvent::KeyPress,
Qt::Key_C,
Qt::ControlModifier ));
QApplication::postEvent( focused,
new QKeyEvent( QEvent::KeyRelease,
Qt::Key_C,
Qt::ControlModifier ));
}

wish of those help JSON RPC expects the client to send parameters to the server using an HTTP POST command with the procedure parameters in the post data. When you type a URL into the browser it sends an HTTP GET command, which doesn't send any parameters. RPC is intended for use by application programs, not directly by end users. See http://json-rpc.org/ for more details about it.

wish help you to fix your issue Package time code :

import (
"encoding/json"
"fmt"
"strings"
"time"
)
type MyTime struct {
time.Time
}
func (m *MyTime) UnmarshalJSON(data []byte) error {
// Ignore null, like in the main JSON package.
if string(data) == "null" || string(data) == `""` {
return nil
}
// Fractional seconds are handled implicitly by Parse.
tt, err := time.Parse(`"`+time.RFC3339+`"`, string(data))
*m = MyTime{tt}
return err
}
type Added struct {
Added MyTime `json:"added"`
}
func main() {
st := strings.NewReader(`{"added": "2012-04-23T18:25:43.511Z"}`)
var a Added
err := json.NewDecoder(st).Decode(&a)
if err != nil {
panic(err)
}
fmt.Println(a)

 Unable to locate element: {"method":"xpath","selector":"//*[@id="react-root"

hope this fix your issue AFAIK, you're trying to reach the phone number input field on instagram main page. However, the locator is working, I've checked just now. The probable reason is in page loading. There is a pre-loader on instagram website which loads page ~1-2sec. In this case try to use ImplicitWait instead of sleep. Just put it right after driver.get(url) : code :
driver.manage().timeouts().implicitlyWait(7, TimeUnit.SECONDS);
