cant compile windows form application?

this is my first time messing around with the windows form application, it seems like it doesnt not compile code as a normal console program does. heres what im trying to do, make a start and stop, and a exit button. it compiles and runs when i just have Application::Exit(); but my code in button1 throws an error when i compile.

Code:

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
		if (GetAsyncKeyState(VK_CAPITAL)){
		Sleep( 85 );
		keybd_event( VK_LBUTTON,0x1,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYDOWN,0);
		Sleep( 85 );
        keybd_event( VK_LBUTTON,0x1,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
	}
 }

	private: System::Void button3_Click(System::Object^  sender, System::EventArgs^  e) {
				 Application::Exit();
			 }
	private: System::Void button2_Click(System::Object^  sender, System::EventArgs^  e) {
			 }
	};

Knowing how to understand what the compiler is saying to you and how to fix it is part of being a programmer.

Also, im not a psychic to know what error that code is giving you without you telling me.
