How to Get ie history and clear ie history

Related interfaces: iurlhistorystg, ienumstaturl, iurlhistorystg2 related methods: Iurlhistorystg: enumurlsThis method returns an ienumstaturl interface pointer, which is used to enumerate ie history records. Lresult Ienumstaturl :: Next (ulong Celt, lpstaturl rgelt, ulong * pceltfetched) Parameter description: CeltThe value cannot be 0, but can be set to 1. RgeltIs a staturl structure pointer that is filled by a MS-IE. PceltfetchedReturned by the method. 1 indicates that the rgelt structure is successfully filled. To use the data in the second parameter, you should determine whether the value is 1. Header file: urlhist. h The following is a code example (required header file: comdef. h, afxtempl. h): bool gethistory (cstringlist & list) {staturl URL; cstring strurl; ulong ufetched; invalid history; ienumstaturlptr enumptr; If (failed (cocreateinstance (temperature, null, temperature, (void **) & History) {return false;} If (failed (history-> enumurls (& enumptr) return false; while (succeeded (enumptr-> next (1, & URL, & ufetched) {If (ufetched = 0) break; strurl = URL. pwcsurl; List. addtail (strurl);} return true;} another useful method: Lresult ienumstaturl: setfilter (lpcolestr poszfilter, DWORD dwflags );You can call this method to set the filter before calling next enumeration history. How should I set poszfilter? Determine whether the URL matches poszfilter completely or the prefix. For example, enumptr-> setfilter (L "HTTP", staturl_queryflag_iscached); then the recorded URL is enumerated by next only when it starts with HTTP. Set poszfilter to RES and file to get different types of URLs. Another method: ClearhistoryYou can call this operation to clear all historical records, but note that this method belongs to the iurlhistorystg2 interface.
