C#+Winform : Aero 特效的快速搜尋框

平時上網都會用到搜尋引擎，但是每次都要去開啟瀏覽器，然後開啟百度或Google。。。   這樣做總覺得很煩 ！ 為了不讓自己能快點搜出東西，我就做了小工具  QuickSearch         

其實實現原理很簡單：

就是先去找到那些搜尋引擎的搜尋字串，例如百度的 http://www.baidu.com/s?wd= ，我們只需要在=後面加想搜的關鍵字就能搜到我們想要的內容，不過百度的關鍵字是utf-8編碼的，所以我們就要進行編碼轉換 應為我是用C#開發 預設的是Unicode編碼 

 轉換方法：先添加應用 System.Web，

   string result = System.Web.HttpUtility.UrlEncode(word, System.Text.Encoding.GetEncoding("utf-8"));

為了方便我還添加了快速鍵：Ctrl+Q 實現快速顯示表單

Code:

    [System.Runtime.InteropServices.DllImport("user32.dll")] //申明API函數
　     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函數
        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);
        }


//顯示 or 隱藏
     private void hidWindows()
        {
if (this.Visible == false)
            {
this.Visible = true;
this.TopMost = true;
            }
else
            {
this.Visible = false;
            }
        }

註冊快速鍵：
/*        None = 0,   
            Alt = 1,   
            Ctrl = 2,   
            Shift = 4,   
            WindowsKey = 8  */
       RegisterHotKey(Handle, 101, 2, Keys.Q);

為了好看還加入Aero特效 這是Windows7內建的效果 ，直接寫了類

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;
        }
    }
}

搜尋代碼：

            string result = System.Web.HttpUtility.UrlEncode(word, System.Text.Encoding.GetEncoding("utf-8"));

switch (btnSearch.ButtonText)
            {
case "百度一下":
                    Process.Start(@"http://www.baidu.com/s?wd=" + result);
this.TopMost = false;
break;
case "Google":
                    Process.Start(@"http://www.google.com.hk/search?q=" + result);
this.TopMost = false;
break;
case "有道搜尋":
string youdao = HttpUtility.UrlEncode(word, Encoding.GetEncoding("gbk"));
                    Process.Start(@"http://www.youdao.com/search?q=" +youdao);
this.TopMost = false;
break;
case"搜搜":
string soso=HttpUtility.UrlEncode(word,Encoding.GetEncoding("gbk"));
                    Process.Start(@"http://www.soso.com/q?pid=s.idx&w="+soso);
this.TopMost = false;
break;
case "MSDN":
this.TopMost = false;
                    Process.Start(@"http://social.msdn.microsoft.com/Search/zh-cn?query=" + result + "+");
break;
            }
this.Visible = false;
            txtKeyWord.Text = "";
        }
