Need help with some basic C++

Hello all,

For a while now I have been trying to code an application that has two windows forms containing the following:

Form 1: A web browser and menu strip with 1 button

Form 2: A textbox and 2 buttons


What I am trying to do here is have the menu strip button open Form2, and when the user presses the "ok" button on form2, call the webbrowser1's navigate function.

However, i cannot seem to do this!!

Any help is appreciated!

Your problem is on that line and your technique is wrong. Fix that line, and maybe the other spot, and make sure your code conforms to the C++ standard.

(Hint: Provide real information on what doesn't work and maybe someone will provide real solutions ;) )

Well, I guess what it comes down to is, I need to know how to access members of a seperate class (ie Buttons ect.)

And I cant provide any real information, because this is the first piece of code that needs to be written, and I have tried and failed, leaving me with two brand new forms.

Any further help appreciated!!

So if you can't show us what you're doing, how are we supposed to know how you're screwing up?

If you're lost on the basics of the language, start with a good tutorial or a good book and start learning the language. Also, I would recommend that you start learning how to write console programs, before GUI programs, since GUI programs usually demand a lot more knowledge of the language to be able to make them.

Class or Object? If class, you probably mean static members.

Code:

---

ClassName::memeber(<param>);

---

If object, you need to have a reference to that object to be able to use it's funtions.

Code:

---


class B
{
public:
  void member_of_B()
  {
        cout << "B here!\n";
  }
};



Class A
{

  B& b_ref;

public:
  A(const B& reference_to_B_object)
  :    b_ref(reference_to_B_object)
  {}

    void use_member_of_class_B()
    {
        b_ref.member_of_B();
    }

};



int main()
{

  B b;  // create B object
  A a(b); // create A object and pass it a reference to the object of class B from above
  a.use_member_of_class_B(); // A accesses a non-static  member of class B

    return 0;
}

---

or place A and B in a stronger (has-a) relation:

Code:

---


class B
{
public:
  void member_of_B()
  {
        cout << "B here!\n";
  }
};


Class A
{

  B b;

public:
  A()
  :    b()
  {}

    void use_member_of_class_B()
    {
        b.member_of_B();
    }

};




int main()
{

  A a; // create A object whose constructor creates a B object
  a.use_member_of_class_B(); // A accesses a non-static  member of class B

    return 0;
}

There is nothing "basic" about GUI programming! In fact, there is no GUI in ANSI/ISO Standard C++. (There is no mouse, graphics, color, or sound, in Standard C/C++.) This is an advanced topic.

So, you need to tell us what GUI library you are using and what operating system you are running. If you are programming for Microsoft Windows, there is a Windows Forum. And, if you are using the Win32API, The Forgers Windows Programming Tutorial is a good start.

well, i will try the windows forum.

Thanks for you guy's time.

I'm native to visual basic, and the console and GUI programs in VB are not really any different.

so sorry for any trouble I may have caused, im very sorry!

Thanks
