如何得到桌面窗口的句柄(桌面图标)

包含图标的窗口实际上是DesktopWindow的一个子窗口。确切地讲，Desktop Window包含一个无标题的、类名为“SHELLDLL_DefView”的子窗口，这个子窗口又包含一个无标题的、类名为“SysListView32”的子窗口——这才是那个真正包含桌面图标的窗口。桌面图标是放在 SysListView32这个列表中，下面得到了它的句柄，

HWND  hwndParent = ::FindWindow(L"Progman", L"Program Manager"); HWND  hwndSHELLDLL_DefView = ::FindWindowEx(hwndParent,NULL, L"shelldll_defview", NULL); HWND  hwndSysListView32 = ::FindWindowEx(hwndSHELLDLL_DefView, NULL, L"SysListView32", L"FolderView");

说明：'ProgMan'是Windows桌面的默认类名，我们平时看到的桌面的图标所在，默认情况下是一个Listview，属于ProgMan的一个子窗口，父子关系如下：

 类名：Progman 窗口标题：Program Manager     类名：SHELLDLL_DefView         类名：SysListView32 窗口标题：FolderView 

抓图工具截图如下：

如何遍历它得到各个桌面图标的句柄呢？ 如果桌面上有文件夹，文件什么的怎么分辨？以下三句得到列表的句柄，哪个能告诉我下面该怎么做，我的目标是通过 MoveWindow函数来任意改变桌面上所有图标的位置。。。 

<pre name="code" class="cpp">void C***::OnSetDeskIcon() {    	HWND  hwndParent = ::FindWindow( "Progman", "Program Manager" ); 	HWND  hwndSHELLDLL_DefView = ::FindWindowEx( hwndParent, NULL, "SHELLDLL_DefView", NULL ); 	HWND  hwndSysListView32 = ::FindWindowEx( hwndSHELLDLL_DefView, NULL, "SysListView32", "FolderView" );	int Nm = ListView_GetItemCount( hwndSysListView32 );		int sNm = 0;	if( Nm >= 10 )	{		sNm = 10;	}	else	{		sNm = Nm;	}		for( int i = 0; i < sNm; i++ )	{		int x = 400 + 150*cos( i*36*3.1415926/180 );		int y = 400 + 150*sin( i*36*3.1415926/180 );		::SendMessage( hwndSysListView32,   LVM_SETITEMPOSITION, i,   MAKELPARAM( x,y));	}		ListView_RedrawItems(hwndSysListView32, 0, ListView_GetItemCount(hwndSysListView32) - 1);	::UpdateWindow(hwndSysListView32);}上面的代码 实现把桌面前10图标排成一个圆 楼主去查ListView_RedrawItems这类函数的用法
