哪位高人懂AnimateWindow的运用？

Question

using System.Runtime.InteropServices; [DllImport("user32.dll")] 
extern static bool AnimateWindow( 
  int hwnd,     // handle to window 
  int dwTime,  // duration of animation 
  int dwFlags  // animation type 
); (下面的也许是多余了....)
各个参数的意义,下面连接.对于的常数,到相应的.h中查,然后在C#相应定义.http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowreference/windowfunctions/animatewindow.asp同时参考这篇文章

Answer 1

名称“AW_VER_NEGATIVE”在类或命名空间“Project4.Form1”中不存在
还是有错 ：（

Answer 2

这是在VC中定义的常量.
如果你看我贴给你的那个MSDN的连接,在连接的尾部,就会看到这些常量都定义在winusr.h中. 这些.h文件都在vc/vc.net的include目录下. 
(本来想让你自己找找,我还是给你贴上来吧).在C#中可以这样定义:
private const int AW_VER_NEGATIVE = 0x00000008;
/*
 * AnimateWindow() Commands
 */
#define AW_HOR_POSITIVE             0x00000001
#define AW_HOR_NEGATIVE             0x00000002
#define AW_VER_POSITIVE             0x00000004
#define AW_VER_NEGATIVE             0x00000008
#define AW_CENTER                   0x00000010
#define AW_HIDE                     0x00010000
#define AW_ACTIVATE                 0x00020000
#define AW_SLIDE                    0x00040000
#define AW_BLEND                    0x00080000
