class Win32API
        {
            [DllImport("User32.dll")] //User32.dll是Windows操作系统的核心动态库之一
            public static extern int FindWindow(string lpClassName, string lpWindowName);

            [DllImport("user32", EntryPoint = "RegisterWindowMessage")]
            public static extern int RegisterWindowMessage(

                    int wParam,
                    ref int lParam
            );
            [DllImport("OLEACC.DLL", EntryPoint = "ObjectFromLresult")]

            int lResult,
            ref System.Guid riid,
            int wParam,
            [System.Runtime.InteropServices.MarshalAs(UnmanagedType.Inte易做图ce), System.Runtime.InteropServices.In, System.Runtime.InteropServices.Out]ref System.Object ppvObject
                //注意这个函数ObjectFromLresult的声明.
            );
        }

补充：软件开发 , C# ,

上一个：winfrom 控制窗体间相互传递数据
下一个：C# winfrom 获取按键信息
