    Two-Dimensional Array of Labels

    Hi, I'm taking a college course in C++ so my experience is rather limited. I'm trying to create a two-dimensional array of labels. I'm using the following code but the labels do not show on the form:

    private: array<System::Windows::Forms::Label^> ^LabelArr;
    void InitializeComponent(void)
    this->LabelArr = gcnew array<System::Windows::Forms::Label^>(40);
    for (int x = 0; x < 3; x++)
    this->LabelArr[x]=(gcnew System::Windows::Forms::Label());
    this->LabelArr[x]->Visible = true;
    this->LabelArr[x]->Enabled = true;
    this->LabelArr[x]->AutoSize = true;
    this->LabelArr[x]->BackColor = System:rawing::Color::Red;
    this->LabelArr[x]->Location = System:rawing::Point(29*x, 13*x);
    this->LabelArr[x]->Name = L"LabelArr";
    this->LabelArr[x]->Size = System:rawing::Size(29, 13);
    this->LabelArr[x]->TabIndex = 0;
    this->LabelArr[x]->Text = L"label";


    Also, I can't look at my form withou running the program.

    This is C++/CLI, which is not the same language as C++.

    There's nothing two-dimensional about your array, either. And as far as I can see, you're never adding the labels you create to the parent component, e.g. by calling this->Add(this->LabelArr[x]).

    As for why you can't look at the form, I don't know. Perhaps the Forms designed doesn't work for C++/CLI. You could always write it in C# - if your "college course on C++" doesn't actually teach C++, what difference would it make?
    All the buzzt!
