桌面清理工具

先看一下界面。

主界面如 ：

 然后是被清理的桌面项的浏览：

接下来是配置不清理项：

 

本软件的主要工作原理是：

1）配置不清理项。

2）一键清理，被配置的不清理项不会被清理，会留在桌面上，其它文件会被移动到 ./DesktopFiles的目录下。

3）快速查看被清理的桌面项，提供搜索功能。

很简单。

 

其中要处理的细节，代码贴如下：

1.显示桌面时，程序界面不隐藏：

1）在 OnInitInstance ():
CDesktopCleanDlg* pdlg = NULL;
    HWND hwnd = FindWindow (TEXT("Progman"), NULL);
    hwnd = ::GetWindow(hwnd, GW_CHILD);
    CWnd* pDesk = CWnd::FromHandle(hwnd);
    pdlg = new CDesktopCleanDlg (pDesk);
    pdlg->Create (CDesktopCleanDlg::IDD, pDesk);

    MSG msg;
    while (GetMessage (&msg, NULL, 0, 0)) {
        if (msg.message == WM_QUIT) {
            break;
        } else {
            TranslateMessage(&msg);
            DispatchMessage (&msg);
        }
    }

    pdlg->DestroyWindow();
    delete pdlg;
采用非模态对话框进行构建。

2）在MainDlg里设置定时器，定时器内如下处理：
if (!m_pwndDesktopShow->IsWindowVisible()) // 
    ShowWindow(SW_SHOWNA);

2.根据文件首字进行自动划分其实所属类别，如“我”-W，“你”-N，“2”-E等等。（转载）

3.获取桌面文件，注意，桌面文件比较特别，它有可能存在有不同用户的桌面文件，故不能用获取桌面文件夹的方式进行FindFirstFile, FindNextFile 进行文件枚举，这里采用COM枚举的方式（转载）：

TCHAR MyDir[_MAX_PATH];  
    SHGetSpecialFolderPath(this->GetSafeHwnd(),MyDir,CSIDL_DESKTOP,0);

    TCHAR szExcept1 [MAX_PATH];
    _stprintf (szExcept1, TEXT ("%s\\desktop.ini"), MyDir);

    m_lstCurr.SetImageList(&m_imgList, LVSIL_NORMAL);

    SHFILEINFO   sfi;
    HICON hIcon;

    HRESULT   hr; 
    hr=CoInitialize(NULL); 
    if   (SUCCEEDED(hr)) 
    { 
        IMalloc   *pMalloc; 
        IShellFolder   *pFolder; 
        IEnumIDList   *pEnumIDList; 

        hr=SHGetMalloc(&pMalloc); 
        hr=SHGetDesktopFolder(&pFolder); 

        LPITEMIDLIST   pIDList; 

        hr=pFolder->EnumObjects (NULL,SHCONTF_STORAGE, &pEnumIDList); 

        STRRET   strBuf; 
        LPTSTR   pszName; 
        HRESULT   hrEnd; 
        int i = 0;
        do 
        {
            hrEnd=pEnumIDList->Next(1,&pIDList,NULL); 

            hr=pFolder->GetDisplayNameOf(pIDList,SHGDN_FORPARSING,&strBuf); 
            hr=StrRetToStr(&strBuf,pIDList,&pszName); 


            if (_tcsicmp (pszName, szExcept1) != 0 && _tcsicmp (pszName, MyDir) != 0) {
                TCHAR* pszFileName = _tcsrchr (pszName, TEXT ('\\'));
                if (pszFileName == NULL) {
                    pMalloc->Free (pszName); 
                    pMalloc->Free (pIDList);
                    continue;
                }

                pszFileName += 1;
                if (!PathIsDirectory (pszName))
                    SHGetFileInfo(pszName,0,&sfi,sizeof(sfi),SHGFI_ICON|SHGFI_LARGEICON|SHGFI_USEFILEATTRIBUTES);
                else
                    SHGetFileInfo(pszName,0,&sfi,sizeof(sfi),SHGFI_ICON|SHGFI_LARGEICON|SHGFI_SYSICONINDEX);

                hIcon = sfi.hIcon;
                m_imgList.Add (hIcon);

                //CString str (pszName);
                CStringA strA (pszName);
                char* pszText = new char [strA.GetLength() + 1];
                strcpy(pszText, strA);
                LVITEM item;
                item.mask        = LVIF_IMAGE | LVIF_PARAM | LVIF_TEXT;
                item.cchTextMax    = strA.GetLength() + 1;
                item.lParam        = (LPARAM)pszText;
                item.iItem        = i;
                item.iSubItem    = 0;
                item.pszText    = pszFileName;
                item.iImage        = i;
                m_lstCurr.InsertItem  (&item);
                ++i;
            }
            pMalloc->Free (pszName); 
            pMalloc->Free (pIDList);


        }while(hrEnd == S_OK); 

        pEnumIDList->Release (); 
        pFolder->Release (); 
    } 
    CoUninitialize();

程序还有一些小BUG没有解决，如文件（夹）同名问题，它虽然不会覆盖，但我的程序无法区分。有时候配置不清理项时，会无法显示。后期再维护吧。
