怎麼樣獲取桌面圖標句柄，並用VC完成隨意移動桌面圖標地位置？

桌面圖標是放在 SysListView32這個列表中，下面得到了它的句柄，如何遍歷它得到各各桌面圖標的句柄？
如果桌面上有文件夾，文件什麼的怎麼分辨？以下三句得到列表的句柄，哪個能告訴我下面該怎麼做，我的目標是通過
MoveWindow函數來任意改變桌面上所有圖標的位置。。。
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");

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);


}

上面的代碼 實現把桌面前10圖標排成一個圓 樓主去查ListView_RedrawItems這類函數的用法

謝謝，我還有一個問題，希望你幫我解答一下，答完就結貼給分。
    HWND hDestTop;
    hDestTop = ::FindWindow("progman", NULL);
    hDestTop = ::FindWindowEx(hDestTop, 0, "shelldll_defview", NULL);
    hDestTop = ::FindWindowEx(hDestTop, 0, "syslistview32", NULL);
   
    DWORD dwProcessId;
    GetWindowThreadProcessId(hDestTop, &dwProcessId);
    HANDLE hProcess = OpenProcess(PROCESS_VM_READ | PROCESS_VM_OPERATION, false, dwProcessId);
   
    PVOID rc = VirtualAllocEx(hProcess, NULL, sizeof(RECT), MEM_COMMIT, PAGE_READWRITE);
    m_iconCount = ListView_GetItemCount(hDestTop);
    RECT iRect;
    char szText[200];
    CString rcStr;
    m_iconInfoCtrl.DeleteAllItems();
    for (int i = 0; i < m_iconCount; i++)
    {
        ListView_GetItemText(hDestTop, i, 5, szText, 200); //在這我想得到如“我的電腦”等圖標的文本
                                                          //但不知道如何得，隨便寫的一個。
        ListView_GetItemRect(hDestTop, i, rc, LVIR_ICON); //出錯處,想得到圖標大小
        ReadProcessMemory(hProcess,  rc,  &iRect,  sizeof(RECT), NULL);
        rcStr.Format("(%d,%d,%d,%d)", iRect.left, iRect.top, iRect.right, iRect.bottom);
        m_iconInfoCtrl.InsertItem(i, szText);
        m_iconInfoCtrl.SetItemText(i, 1, rcStr);
    }
    VirtualFreeEx(hProcess, rc, 0, MEM_RELEASE);
    CloseHandle(hProcess);
    UpdateData(false);
用上面的方法我是想把桌面上的圖標數量和圖標的大小顯示出來，結果在上面標紅的地方出錯，如果我不在explorer進程中開空間的話，讀出來的大小是不對的，結果都是1，和一個很小的負數。。要得到大小和圖標上的文本應該如何寫？

下面這個函數純屬抄襲了：http://www.codeproject.com/KB/threads/int64_memsteal.aspx
在上面增加了取得 Rect的部分
C/C++ code

void C***::OnSetDeskIcon()


{
    HWND hDestTop; 


    hDestTop = ::FindWindow("progman", NULL); 


    hDestTop = ::FindWindowEx(hDestTop, 0, "shelldll_defview", NULL); 


    hDestTop = ::FindWindowEx(hDestTop, 0, "syslistview32", NULL); 


    int count=(int)::SendMessage( hDestTop, LVM_GETITEMCOUNT, 0, 0);


    LVITEM lvi, *_lvi;


    char item[512], subitem[512];


    char *_item, *_subitem;


    unsigned long pid;


    HANDLE process;


    GetWindowThreadProcessId( hDestTop, &pid);

    RECT  rc;


    rc.left = LVIR_ICON;  //這個一定要設定 可以去看MSDN關於LVM_GETITEMRECT的說明


    RECT* _rc =(RECT*)VirtualAllocEx( process, NULL, sizeof(RECT), MEM_COMMIT, PAGE_READWRITE); 


    lvi.cchTextMax=512;


    for( int i=0; i< 10; i++) {

        str.Format("LF:%d TP:%d RT:%d BT:%d", rc.left,rc.top,rc.right,rc.bottom);


        AfxMessageBox(str);


        str.Format("%s - %s/n", item, subitem);


        AfxMessageBox( str );


    }


    VirtualFreeEx(process, _lvi, 0, MEM_RELEASE);


   VirtualFreeEx(process, _item, 0, MEM_RELEASE);


    VirtualFreeEx(process, _subitem, 0, MEM_RELEASE);


    VirtualFreeEx(process, _rc, 0, MEM_RELEASE);


    CloseHandle( process );



}



 我這裏試驗通過了。
