点击页面中的一按钮,显示计算机桌面

当任务栏里没有“显示桌面图标”时  可在记事本中写:

[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop

备注:保存成.scf 格式

 

javascript:
<script language="JScript">
    function fnIShellDispatch4ToggleDesktopJ()
    {
        var objShell = new ActiveXObject("shell.application");
       
        objShell.ToggleDesktop();
    }
</script>

VBScript:
 <script language="VBScript">
    function fnIShellDispatch4ToggleDesktopVB()
        dim objShell
       
        set objShell = CreateObject("shell.application")
            objShell.ToggleDesktop
        set objShell = nothing
    end function
 </script>

 

Visual Basic:
 Private Sub fnIShellDispatch4ToggleDesktopVB()
    Dim objShell As Shell
           
    Set objShell = New Shell
        objShell.ToggleDesktop
    Set objShell = Nothing
End Sub

 

C++实现显示桌面:

/*
程序: 显示桌面 C++ 实现
说明: IShellDispatch4 接口只有WINDOWS XP以上的操作系统才支持,需要 shell32.dll 5.0或以上版本
编译环境: Microsoft Visual Studio 2008
*/
#include <windows.h>
#include <shldisp.h>

int main()
{
CoInitialize(0);
IShellDispatch4 * pdisp=NULL;
CoCreateInstance(CLSID_Shell,NULL,CLSCTX_ALL,__uuidof(IShellDispatch4),(void **)&pdisp);
pdisp->ToggleDesktop();
pdisp->Release();
CoUninitialize();
return 0;
}

C#实现显示桌面: 在vs2003中没有反应,在vs2005中可行,已测试

/*
* 程序 : 显示桌面 C# 实现
* 编译环境 : Microsoft Visual Studio 2008
*/
using System;
using System.Reflection;

namespace CSCONSOLE
{
    class Program
    {
        public static void Main(string [] args)
        {
            Type oleType=Type.GetTypeFromProgID("Shell.Application");
            object oleObject=System.Activator.CreateInstance(oleType);
            oleType.InvokeMember("ToggleDesktop",BindingFlags.InvokeMethod,null,oleObject,null);
        }
    }
}

 

SCF文件是“WINDOWS资源管理器命令”文件,它也是一种可执行文件.
  该类型文件由Windows Explorer Command解释,标准安装,包括下面3个该类型的文件
  ===========================
  1) Explorer.scf(资源管理器)
  [Shell]
  Command=2
  IconFile=explorer.exe,1
  [Taskbar]
  Command=Explorer
  ===========================
  2)Show Desktop.scf(显示桌面)
  格式类似如下:
  [Shell]
  Command=2
  IconFile=explorer.exe,3
  [Taskbar]
  Command=ToggleDesktop
  ===========================
  3)View Channels.scf(查看频道)
  [Shell]
  Command=3
  IconFile=shdocvw.dll,-118

 

创建桌面快捷方式
<script language="javascript">
   var url = "C:\\Documents and Settings\\Administrator.WBT-E231DA542FA\\Application Data\\Microsoft\\Internet Explorer\\Quick Launch\\显示桌面.scf";
   var lnk = "桌面快捷方式";
   var fso = new ActiveXObject("Scripting.FileSystemObject");      
   var shell = new ActiveXObject("WScript.Shell");
   var DesktopPath = shell.SpecialFolders("Desktop");
   if(!fso.FolderExists(DesktopPath))
   {
    fso.CreateFolder(tagFolder); */
    //fso.CreateFolder(DesktopPath);
   }
   if(!fso.FileExists(DesktopPath + "\\"+lnk+".lnk"))
   {     
    var link = shell.CreateShortcut(DesktopPath + "\\"+lnk+ ".lnk");
     
    link.Description = "用JS生成客户端快捷方式";                      
    link.TargetPath = url;
    link.WindowStyle = 1;                      
    link.Save();                             
   }
  </script>
