Undeclared Identifier when trying to use an object

[Tineras]

I created an object array when a button is clicked. When I try to use any of the objects in another function, it is saying that it's an undeclared identifier.

What do I need to do to make sure I can use 'picBlocks[k]' anywhere else in my code?

Object Array created here:
public: System::Void menuFile_Click(...)
{
      PictureBox* picBlocks[] = new PictureBox*[5];

      for(int i = 0; i < 5; i++)
      {
        picBlocks[i] = new PictureBox();
        pnlGameField->Controls->Add(picBlocks[i]);
      }
}

Trying to access object here in a different function:
bool OtherFunction()
{
   if(picBlocks[0] = xxxx) <---says picBlocks is undeclared
   {
      Blah Blah Blah
   }
}

I still new to programming, so the more details, the better. I was told previously that I needed to add picBlocks[] to a class. I don't really know how to do that.

Thanks for the help!

Declare the variable outside of the functions body:

class YourClass
{
public:
    // declared at class scope (can be accessed from all member functions)
    int i;

    void functionA()
    {
        i = 5; // ok

        int j; // declared in function scope, can only be accessed from this function
        j = 5; // ok;
    }

    void functionB()
    {
        i = 5; // ok

        j = 5; // not ok!
    }
};

What about reading a good C++ book?
