C#+Winform : Aero 特效的快速搜索框
平时上网都会用到搜索引擎，但是每次都要去打开浏览器，然后打开百度或谷歌。。。 这样做总觉得很烦 ！ 为了不让自己能快点搜出东西，我就做了小工具 QuickSearch 
其实实现原理很简单：
就是先去找到那些搜索引擎的搜索字符串，例如百度的 http://www.baidu.com/s?wd= ，我们只需要在=后面加想搜的关键字就能搜到我们想要的内容，不过百度的关键字是utf-8编码的，所以我们就要进行编码转换 应为我是用C#开发 默认的是Unicode编码
转换方法：先添加应用 System.Web，
string result = System.Web.HttpUtility.UrlEncode(word, System.Text.Encoding.GetEncoding("utf-8"));
为了方便我还添加了快捷键：Ctrl+Q 实现快速显示窗体
Code:
[System.Runtime.InteropServices.DllImport(
"
user32.dll
"
)]
//
申明API函数
public
static
extern
bool
RegisterHotKey(
IntPtr hWnd,
//
handle to window
int
id,
//
hot key identifier
uint
fsModifiers,
//
key-modifier options
Keys vk
//
virtual-key code
);
[System.Runtime.InteropServices.DllImport(
"
user32.dll
"
)]
//
申明API函数
public
static
extern
bool
UnregisterHotKey(
IntPtr hWnd,
//
handle to window
int
id
//
hot key identifier
);
protected
override
void
WndProc(
ref
Message m)
{
const
int
WM_HOTKEY
=
0x0312
;
if
(WM_HOTKEY
==
m.Msg)
{
if
(m.WParam.ToInt32()
==
101
)
{
hidWindows();
}
}
base
.WndProc(
ref
m);
}
//
显示 or 隐藏
private
void
hidWindows()
{
if
(
this
.Visible
==
false
)
{
this
.Visible
=
true
;
this
.TopMost
=
true
;
}
else
{
this
.Visible
=
false
;
}
}
注册快捷键：
/*
None = 0,
Alt = 1,
Ctrl = 2,
Shift = 4,
WindowsKey = 8
*/
RegisterHotKey(Handle,
101
,
2
, Keys.Q);
为了好看还加入Aero特效 这是Windows7自带的效果 ，直接写了类
using
System;
using
System.Drawing;
using
System.Runtime.InteropServices;
using
System.Windows.Forms;
namespace
QuickSearch
{
public
partial
class
AeroForm
{
[DllImport(
"
dwmapi.dll
"
)]
private
static
extern
void
DwmExtendFrameIntoClientArea(IntPtr hWnd,
ref
MARGINS pMargins);
[StructLayout(LayoutKind.Sequential)]
private
struct
MARGINS
{
public
int
left, right, top, bottom;
}
public
static
void
AeroEffect(Form f1)
{
MARGINS m
=
new
MARGINS()
{
left
=
-
1
};
DwmExtendFrameIntoClientArea(f1.Handle,
ref
m);
Color aeroColor
=
Color.FromArgb(
164
,
212
,
211
);
f1.TransparencyKey
=
aeroColor;
f1.BackColor
=
aeroColor;
}
}
}
搜索代码：
string
result
=
System.Web.HttpUtility.UrlEncode(word, System.Text.Encoding.GetEncoding(
"
utf-8
"
));
switch
(btnSearch.ButtonText)
{
case

:
Process.Start(
