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：
View Code
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）：
View Code
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();
4.定位文件（夹）位置，我有博客写了这个算法，现在再贴一次吧。
View Code
#ifndef ExploreFileH #define ExploreFileH #include <Windows.h> #include <Shlobj.h> #ifdef UNICODE #define ExploreFile ExploreFileW #elif _UNICODE #define ExploreFile ExploreFileW #else #define ExploreFile ExploreFileA #endif BOOL ExploreFileW (const wchar_t* pwszFile) { LPITEMIDLIST pidl; LPCITEMIDLIST cpidl; IShellFolder* pDesktopFolder; ULONG ulEaten; DWORD dwAttributes; HRESULT hr; HKEY hKey; static wchar_t* s_pszSubKey = L"SOFTWARE\\Microsoft\\Windows\\CurrentVersion"; if (pwszFile == NULL) { return FALSE; } ulEaten = wcslen (pwszFile); if (FAILED (SHGetDesktopFolder (&pDesktopFolder))) { return FALSE; } if (pwszFile [0] != L'{') { hr = pDesktopFolder->ParseDisplayName ( NULL, 0, (LPOLESTR)pwszFile, &ulEaten, &pidl, &dwAttributes); } else { // CLSID DWORD dwProductIdLen = 256; wchar_t szProductId [256] = {0}; wchar_t szPathClsid [MAX_PATH] = {0}; // 获取本机CLSID if (ERROR_SUCCESS != RegOpenKeyExW (HKEY_LOCAL_MACHINE, s_pszSubKey, 0, KEY_READ, &hKey)) { pDesktopFolder->Release (); return FALSE; } DWORD dwType = REG_SZ; if (ERROR_SUCCESS != RegQueryValueExW (hKey, L"ProductId", 0, &dwType, (LPBYTE)szProductId, &dwProductIdLen)) { pDesktopFolder->Release (); RegCloseKey (hKey); return FALSE; } RegCloseKey (hKey); wsprintfW (szPathClsid, L"{%s}}\\::%s", szProductId, pwszFile); hr = pDesktopFolder->ParseDisplayName ( NULL, 0, (LPOLESTR)szPathClsid, &ulEaten, &pidl, &dwAttributes); } if (FAILED (hr)) { pDesktopFolder->Release (); return FALSE; } cpidl = pidl; CoInitialize (NULL); if (FAILED (SHOpenFolderAndSelectItems ( cpidl, 0, NULL, NULL))) { pDesktopFolder->Release (); CoUninitialize (); return FALSE; } pDesktopFolder->Release (); CoUninitialize (); return TRUE; } BOOL ExploreFileA (const char* pszFile) { wchar_t wszFile [MAX_PATH + 1] = {0}; if (!MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, pszFile, -1, wszFile, MAX_PATH)) { return FALSE; } return ExploreFileW (wszFile); } #endif // ExploreFileH
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。
