Undeclared Identifier when trying to access an object

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:

Code:

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
   }
}

edit:
This is for Visual C++ .NET. It's a Windows Forms Application.

Thanks for the help!

picBlocks is a local variable to your menuFile_Click function. To be able to access it in another function, you'll have to either pass it as an argument, or put it in place where it is visible to both functions (Either global, or as a member variable if both functions are within the same class.)

I would prefer to make it a class member, but I'm not sure how to do that. I'm still learning and my teacher doesn't help us out very much.

*bump*

I just need to know how to add picBlocks[j] as a class member. If you need additional code accurately anser this question, I'd be glad to post it.

Thanks

As a class member of what?

What are you doing, overall? There could be a better solution to your general problem.

Class members are declared thusly:

Code:

class Foo
{
public:
   int myPublicMember;
private:
   int myPrivateMember;
};

This will make myPublicMember and myPrivateMember available in any function of class Foo. So, if you want to do things this way, you'll need to figure out which object design encloses whichever functionality you're trying to program, and add your picBlocks variable in there. And since picBlocks is most obviously using Windows Forms, and that Windows Forms are C++/CLI, additional constraints may come to be.

If your teacher isn't being helpful in the whole object/class design department, you're probably better off jsut making it a global variable for now until you more firmly grasp the basics of Object-oriented programming.
