Windows Programming uses recursive methods to traverse files

In the forum, beginners often encounter problems that do not know how to traverse files. In fact, it is very easy to use the following code.

Void ChkRecurse (LPCTSTR pstr/* = NULL */) {CFileFind finder; // build a string with wildcards CString strWildcard (pstr); strWildcard + = _ T ("\\*. * "); // start working for files BOOL bWorking = FALSE; try {bWorking = finder. findFile (strWildcard);} catch (CException * e) {char szCause [255] = {0}; e-> GetErrorMessage (szCause, 255 ); log-> LogOutEx (szCause);} while (bWorking) {try {bWorking = finder. FindNextFile (); // skip. and .. files; otherwise, we 'd // recur infinitely! If (finder. isDots ())//'. and '.. 'Continue; if (finder. isSystem () // System File continue; else if (finder. isDirectory () // directory {CString str = finder. getFilePath (); CString str1; GetDirName (str, str1); if (str1.GetLength () = 12 & _ is_num (str1) {ChkRecurse (str ); // callback} else {Sleep (20); continue ;}} else {// check the file // Do your work ...}} catch (CException * e) {char szCause [255] = {0}; e-> GetErrorMessage (szCause, 255); Log-> LogOutEx (szCause);} finder. close ();}
