阁下这么客气 :)看下面的代码片断。using System.Runtime.InteropServices;
private void Form2_Load(object sender, System.EventArgs e)
{
Win32.AnimateWindow(this.Handle,500, Win32.AW_BLEND);
}
public class Win32
{
public const Int32 AW_HOR_POSITIVE = 0x00000001;
public const Int32 AW_HOR_NEGATIVE = 0x00000002;
public const Int32 AW_VER_POSITIVE = 0x00000004;
public const Int32 AW_VER_NEGATIVE = 0x00000008;
public const Int32 AW_CENTER = 0x00000010;
public const Int32 AW_HIDE = 0x00010000;
public const Int32 AW_ACTIVATE = 0x00020000;
public const Int32 AW_SLIDE = 0x00040000;
public const Int32 AW_BLEND = 0x00080000;
[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern bool AnimateWindow(
IntPtr hwnd, // handle to window
int dwTime, // duration of animation
int dwFlags // animation type
);
}
private void Form2_Load(object sender, System.EventArgs e)
{
Win32.AnimateWindow(this.Handle,500, Win32.AW_BLEND);
}
public class Win32
{
public const Int32 AW_HOR_POSITIVE = 0x00000001;
public const Int32 AW_HOR_NEGATIVE = 0x00000002;
public const Int32 AW_VER_POSITIVE = 0x00000004;
public const Int32 AW_VER_NEGATIVE = 0x00000008;
public const Int32 AW_CENTER = 0x00000010;
public const Int32 AW_HIDE = 0x00010000;
public const Int32 AW_ACTIVATE = 0x00020000;
public const Int32 AW_SLIDE = 0x00040000;
public const Int32 AW_BLEND = 0x00080000;
[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern bool AnimateWindow(
IntPtr hwnd, // handle to window
int dwTime, // duration of animation
int dwFlags // animation type
);
}
this.Opacity = 0;
然后启动一个Timer
在里面
if(this.Opacity<100)
{
this.Opacity += 10.0;//数字按你的要求写
}
不大看的懂啊,讲解下3
