    Question 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++.
    Best regards,

    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...

    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);
