I have a HeaderFile MyProject_Datas.h

//MyProject_Datas.h 
public ref class MyUsefulDatas 
{ 
	blah...blah...blah... 
	public: static System::Void Item_Name( System::Object^ Sender, System::Windows::Forms::KeyEventArgs^ e) { 
	blah...blah...blah... 
	} 
	public: static System::Void Party_Name( System::Object^ Sender, System::Windows::Forms::KeyEventArgs^ e) { 
	blah...blah...blah... 
	} 
}; 

And now from my Form2 - textBox2 I would like to declare

textBox2->KeyDown += gcnew KeyEventHandler(MyUsefulDatas, &MyUsefulDatas::Party_Name); ???????? 

Iam not getting the above line........

Also I would like to learn same statement, how to use in "delegate" statement like the below.....????

textBox2->KeyDown += delegate { .....???????? }

Thanks...
