help you fix your problem i have two wpf pages - Master page and Group page, group page is passing the Entity to Master page constructors, am using dynamic keyword to pass entity, each time a different entity is passing to master page, how can i identify that what entity have been passed to Master page... , You can use GetType like any other object.
code :
    dynamic d = 1; 
    Type t = d.GetType();

like below fixes the issue For a quick and dirty way, you can use the objc_setAssociatedObject and objc_getAssociatedObject of ObjC runtime.
code :
#import <objc/runtime.h>
// static char key;
objc_setAssociatedObject(event, &key, self, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
id yourInterestObj =  objc_getAssociatedObject(event, &key);

wish helps you I have a simple code that accepts two parameters. The parameters are optional. Below is the code.
code :
$MyInvocation.BoundParameters
[CmdletBinding()]
Param(
  [Parameter(Mandatory=$False)]
   [string]$pA,

   [Parameter(Mandatory=$False)]
   [string]$pB
)
$MyInvocation.BoundParameters
PS C:\ps> a -pA pAparam

Key                                                         Value

[bool]($MyInvocation.BoundParameters.Keys -match 'pa') # or -match 'pb' belong your needs
How to identify dynamic listview row separately to identify which row has been clicked

With these it helps You can use this method. In the example i grab some data from the Listview item using (closest). While you dynamically populate the listview items you can insert data attributes -- data-whatever="the data" -- eg (data-address="10 maple Street" data-lat="45.6789" data-lng="56.6786") etc
Demo
code :
<ul data-role="listview" id="listview">
    <li data-id="row1">Row 1</li>
    <li data-id="row2">Row 2</li>
    <li data-id="row3">Row 3</li>
    <li data-id="row4">Row 4</li>
</ul>


$("#listview").on("click", ">li", function(event, ui) {
var id = $(this).closest("li").attr('data-id');
alert(id)
});

it should still fix some issue You can do the following which is often used in certain typeclass based libraries:
code :
trait Foo[H[_] <: Langh[_]]{
  def thing[A](ha: H[A]): A = ha.ha()
}
trait Functor[F[_]]{
  def map[A, B](fa: F[A])(f: A => B): F[B]
}
trait Foo[U]{
  def doStuff(u: U)(implicit ev: MyTypeClass[U]): ev.A = //...
}
trait Whatever[FA]{ /*...*/ }

object Whatever{
  implicit def WhateverMTC[F[_] <: Bound[_], A0] = new MyTypeClass[F[A0]]{
    type A = A0
    //...
   }
 }

wish help you to fix your issue On Unix-like systems, you can use fcntl(fileno(fp), F_GETFL, &flags) to retrieve the flags of the underlying file descriptor. Use the O_ACCMODE mask to obtain the file access mode, which is one of O_RDONLY, O_WRONLY, O_RDWRD and O_APPEND values corresponding to mode strings passed to fopen.
