Constructs a WinWrapper object and attaches it to the specified window handle
XllPlus::Forms::WinWrapper( HWND hwnd );
A valid window handle.
This constructor is all that is required to initialise the object.
Because WinWrapper is a managed class, you should use
to construct it, rather than
new, as shown below.
System::Windows::Forms::MessageBox::Show( gcnew XllPlus::Forms::WinWrapper(hwnd), "Hello from .NET");
