array of buttons... click event ?

Hi I have successfully compiled a code where I created an array of buttons.

I have added a click event to it like this :

Code:

---

buttons[indexofhashis2]->Click += gcnew System::EventHandler(this, &Execute::GOBUT_Click);

---

I have a standard event like this

Code:

---

private: System::Void GOBUT_Click(System::Object^  sender, System::EventArgs^  e) {
                        int x;
x = sender->Location.X;

                        }

---

returns error saying Location is not a member of Object^.

If you don't understand what i want to do :
I'm trying to create an array of button (user/runtime created buttons) and get different interpretations of the click event depending of wich button is clicked.

For example, if we create buttons[0] I wish to get the 0 or something relevant into the GOBUT_Click event.

Any one knows how to do that?

Bad forum. You need to switch to Managed C++.

Igor is right about that you posted this in the wrong place. However, the anser is short, so I'll post it here right away:

Correct: Is isn't. You need to cast the parameter to Control ^ (or a more specific class like Button ^) in order to access control members:

Code:

---

x = safe_cast<Control ^>(sender)->Location.X;

---

I think you're right for Managed C++,
however this forum is mostly empty, I think I would not get an answer there.

And so...

Okay!!!
I need to associate the click on those buttons arrays to the correct interpretation in the GO_BUT::Click event.

So how I do that?


Is it like this or something like that?

Code:

---

private: System::Void GOBUT_Click(System::Object^  sender, System::EventArgs^  e) {
int ID;
Button^ IDBut;
IDBut = sender;

---

EDIT : Returns conversion error. Object^ to Button^
How can I associate the right index of my button array to it?

Sure you will. Trust me... :cool:

Not really surprising: You're trying to do a plain assignment instead of casting (see my example in post #3). In the context of your latest snippet, you need to change the offending line to this:

Code:

---

IDBut = safe_cast<Button ^>(sender);
