Hook Event Handler

Hey pals,

I would like to know how to convert the following code:

__hook(&CSource::MyEvent, pSource, &CReceiver::MyMethod);

To the new managed c++/cli syntax.

Very thanks!

Create new C++/CLI Windows Forms application, add new button to the form and double-click on this button. Windows Form Designer adds this code to Form1.h:

Code:

---

this->button1->Click += gcnew System::EventHandler(this, &Form1::button1_Click);
...
private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e)
{
    ...
}

---

button1 is event source instance.
Click is event
"this" is event receiver instance
button1_Click is receiver method used as event handler.

Every .NET event has a type, which is defined by some delegate. You can define your own delegate or use existing one, like EventHandler. EventHandler defines the following type: Void (Object^, EventArgs^). Click event has EventHandler type. Event handler function should have the same type.

Thanks for your reply.
But I don´t know how to convert the hook keyword into "+=".

This is too much abstract. Show event definition you want to handle.

I want to handle this event:

delegate void del_Event_Connect(UserConnect^ sender);
event del_Event_Connect^ Event_Connect;

And the hook for it:
__hook(&CSource::Event_Connect, pSource, &CReceiver::MyMethod);

Code:

---

EventSourceInstance->Event_Connect += gcnew del_Event_Connect(EventReceiverInstance, &MACHINE_SERVER::Form1::MachineLnk_Connect);

Form1:
void MachineLnk_Connect(UserConnect^ sender)
{
    ...
}

Replace EventSourceInstance and EventReceiverInstance with references to required classes. For example, if subscription is done from Form1, EventReceiverInstance should be "this".

Now it works!
Very thanks Alex!
