Visual studio 2008 如何在表单'；s代码？

代码示例1

//Set Label.
this->TextLabel1= (gcnew System::Windows::Forms::Label());

代码示例2

//When Button Clicked....
TextLabel1->Text = "Button has been pressed";

如何在表单代码之外引用（+更改）已设置的标签。另一个cpp或头文件？

您可以做的一件事是破坏封装，这通常是一件坏事，并将TextLabel1设置为public

因此

变成

public: System::Windows::Forms:Label^ TextLabel1;

现在您可以从调用代码更改TextLabel1：

Form1 ^form = gcnew Form1();
form->TextLabel1->Text = "Text has been changed from the outside.";
Application::Run(form);

Form1 ^form = gcnew Form1();
form->TextLabel1->Text = "Text has been changed from the outside.";
Application::Run(form);
