dll - Powershell Call Assembly Delegate -

-

i have dll assembly our process control application, use load inside powershell script.

the dll contains delegate type need use, delegate name :

"x.y.delegate"

i have method in dll should called way :

method( delegatetype callbackmethod)

so, need :

  1. define delegate in script of type "x.y.delegate" example $mydelegate

  2. define callback method gets invoked when process event triggered"

note: i'm sorry if question seems silly, i'm absolute beginner.

update:

after reading comment , reading question more closely, think might looking utilize asynchronous event handling. below example listens events until timeout reached , exits. example assumes can change assembly add event.

a class generates events:

namespace classlibrary1 {  public class class1  {   public event eventhandler someevent;    protected void onsomeevent(eventargs e)   {    var someevent = someevent;     if (someevent != null)    {     someevent(this, e);    }  }   public void somemethod()  {   task.run(() =>   {    (int = 0; < 3; i++)    {     thread.sleep(3000);     onsomeevent(eventargs.empty);     }    });   }  } }

powershell:

# load .net assembly add-type -path .\class1.cs   $x = new-object classlibrary1.class1  $sourceidentifier = "someevent"  # register event $eh = register-objectevent -sourceidentifier $sourceidentifier -inputobject $x -eventname someevent  $x.somemethod()  while ($true) {  write-host "waiting event..."  $event = wait-event -sourceidentifier $sourceidentifier -timeout 10   if ($event -eq $null)   {   write-host "no event received 10 seconds."    break   }   # processing here  write-host "processing event..."  $event   # remove event queue  remove-event -sourceidentifier $sourceidentifier }  unregister-event -sourceidentifier $sourceidentifier write-host "done processing events."

using jmockit 1.2 jar, trying mock string's length method getting unexpected invocation exception: failed: test java.lang.illegalstateexception: missing invocation mocked type @ point; please make sure such invocations appear after declaration of suitable mock field or parameter @ stringdemo.testa$1.<init>(testa.java:17) @ stringdemo.testa.test(testa.java:13) i using testng: @test public void test() throws exception { new expectations() { @mocked("length") string astring; { astring.length(); result = 2; } }; system.out.println(a.showa("test")); } } actual class a: public class { public static int showa(string str){ int a= str.length(); return a; } } this wrong way of recording expected results. shouldn't mock , record string's length() method, record showa() instead. here solution @suppresswarnings("unused...

What is the difference between data design and data model(ERD) -

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
