Creating array of buttons in Visual C++

Dear All

I have code in C# program:

int myHeight=30;
int myWidth=90;
Button[,] ba = new Button[2, 2];
for (int i=0; i<2;i++)
for (int j = 0; j < 2; j++)
{
ba[i, j] = new System.Windows.Forms.Button();
ba[i, j].Height = myHeight;
ba[i, j].Width = myWidth;
ba[i, j].Location = new Point( i * myWidth,j * myHeight);
ba[i, j].Text = i.ToString() + j.ToString();
panel1.Controls.Add(ba[i, j]);
}

How write it in VC++?

My problem is
Button[,] ba = new Button[2, 2];
I do not know how write it in VC++

thank you

The first question is - why do you need7wnat to create this array in the heap? :confused:
Why not just set the class member variable:

Code:

---

CButton m_arButton[2, 2];

---

Then you could create the button controls using CButton::Create method.
See MSDN for details.

Also MSDN has a couple of good Tutorials in VC++

can you do it without MFC

Sure! but it would be more complex than using MFC.
Create a Win32 project.
Declare the array:

Code:

---

HWND hwndButton[2, 2,];

---

And read MSDN in "Platform SDK: Windows User Interface" section about buttons, button creating and using:
Buttons
Using Buttons

this code

CButton m_arButton[2, 2];
and
HWND hwndButton[2, 2,];

does not work without new *.h files.

this one is working
Button Bbutt ;
but i need more
i trying to use
Button Bbutt [2];
but

What do you mean?
Have you created a new VC++ project? Which type of project?

Sounds like this is a problem (form from C# in the c++ project)!

thanks for all of your for help :)
I need learn more

Anyone used the array of the buttons in C++?
If yes, plz write code with declaration

I already posted you the "code with declaration"! :mad:
If you are not be able to use it properly - it is your problem! However, you are always welcome to get some help. The only thing you have to do in this case - provide some useful information about your problem and the code being used.

If you can't let your project work with an array of buttons - please begin with only one button. After such a project will have worked - change the button declaration to the array and try with it.

Are we talking about Managed C++/CLI? Then we're in the wrong forum, but anyway:

Code:

---

// create 2d array of buttons
cli::array<Button^, 2>^ buttons = gcnew cli::array<Button^, 2>(2, 2);

// initialize buttons
for (int x = 0; x < 2; ++x)
{
    for (int y = 0; y < 2; ++y)
    {
        buttons[x, y] = gcnew Button();

        //...
    }
}

unbelievably...
but fact
It's works :))))))
Thank you

Not really. Probably, Managed C++/CLI? :rolleyes:
