调用 AnimateWindow 函数, 编译时提示: 找不到标识符

我的工程是从 vc++6.0 转换过来的, AnimateWindow 函数为什么在vs2005中不支持,怎么办?谢谢!

AnimateWindow 函数是Windows的API，调用如下：

[DllImport("user32")]
private static extern bool AnimateWindow(IntPtr hwnd,int dwtime,int nflag);
//nflag的取值如下
public const Int32 AW_HOR_POSITIVE = 0x00000001;    //从左到右显示
public const Int32 AW_HOR_NEGATIVE = 0x00000002;    //从右到左显示
public const Int32 AW_VER_POSITIVE = 0x00000004;    //从上到下显示
public const Int32 AW_VER_NEGATIVE = 0x00000008;    //从下到上显示
public const Int32 AW_CENTER = 0x00000010;  //若使用了AW_HIDE标志，则使窗口向内重叠，即收缩窗口；否则使窗口向外扩展，即展开窗口
public const Int32 AW_HIDE = 0x00010000;    //隐藏窗口，缺省则显示窗口
public const Int32 AW_ACTIVATE = 0x00020000;  //激活窗口。在使用了AW_HIDE标志后不能使用这个标志
public const Int32 AW_SLIDE = 0x00040000;    //使用滑动类型。缺省则为滚动动画类型。当使用AW_CENTER标志时，这个标志就被忽略
public const Int32 AW_BLEND = 0x00080000;  //透明度从高到低


CLOSE_OR_OPEN = AW_ACTIVATE; //打开
//CLOSE_OR_OPEN = AW_HIDE; //关闭

IntPtr hwnd = this.Handle;//窗口句柄

animatewindow(hwnd,200,AW_HOR_POSITIVE|CLOSE_OR_OPEN); //从左向右显示 
  
animatewindow(hwnd,200,AW_HOR_NEGATIVE|CLOSE_OR_OPEN); //从右向左显示 
 
animatewindow(hwnd,200,AW_VER_POSITIVE|CLOSE_OR_OPEN); //从上到下显示 
  
animatewindow(hwnd,200,AW_VER_NEGATIVE|CLOSE_OR_OPEN); //从下到上显示 

animatewindow(hwnd,200,AW_SLIDE|AW_HOR_POSITIVE|AW_VER_POSITIVE|CLOSE_OR_OPEN); //左上角伸展 
 
animatewindow(hwnd,200,AW_SLIDE|AW_HOR_POSITIVE|AW_VER_POSITIVE|CLOSE_OR_OPEN); //左下角伸展 
 
animatewindow(hwnd,200,AW_SLIDE|AW_HOR_NEGATIVE|AW_VER_NEGATIVE|CLOSE_OR_OPEN); //右上角伸展 
 
animatewindow(hwnd,200,AW_SLIDE|AW_HOR_NEGATIVE|AW_VER_NEGATIVE|CLOSE_OR_OPEN); //右下角伸展

我是在 vc++ 2005 中开发,代码该怎么写呢? 怎么导入 AnimateWindow 函数?
