清空internet临时文件夹Temporary Internet Files

在XP平台上,直接调用DeleteFile()函数是不能删除临时文件夹里面的文件的!需要调用FindFirstUrlCacheEntry()和FindNextUrlCacheEntry()查找Internet Cache的入口,获取缓存文件夹里文件的信息,然后调用DeleteUrlCacheEntry()删除指定文件名的缓存文件;

添加头文件:wininet.h

添加引入库: Wininet.lib 和 shlwapi.lib

代码如下:

BOOL DeleteTempFile() { BOOL bRet = FALSE; HANDLE hEntry; LPINTERNET_CACHE_ENTRY_INFO lpCacheEntry = NULL; DWORD dwEntrySize; dwEntrySize = 0; hEntry = FindFirstUrlCacheEntry(NULL, NULL, &dwEntrySize); lpCacheEntry = (LPINTERNET_CACHE_ENTRY_INFO) new char[dwEntrySize]; hEntry = (NULL, lpCacheEntry, &dwEntrySize); //从Internet cache中找到特定入口 if (!hEntry) goto cleanup; do { if (!(lpCacheEntry->CacheEntryType & COOKIE_CACHE_ENTRY)) DeleteUrlCacheEntry(lpCacheEntry->lpszSourceUrlName); //删除Cache中指定的文件 dwEntrySize = 0; FindNextUrlCacheEntry(hEntry, NULL, &dwEntrySize); delete [] lpCacheEntry; lpCacheEntry = (LPINTERNET_CACHE_ENTRY_INFO) new char[dwEntrySize]; } while (FindNextUrlCacheEntry(hEntry, lpCacheEntry, &dwEntrySize)); //查找Internet cache的下一个入口 bRet = TRUE; cleanup: if (lpCacheEntry) delete [] lpCacheEntry; return bRet;
