Encapsulating MFC's CFileFind Class
By Graham Pearson, May 01, 2002
CFileFind does a good job of encapsulating the Windows API functions FindFirstFile and FindNextFile and the WIN32_FIND_DATA structure. But making recursive calls to a function containing CfileFind can be cumbersome. Graham created a class called CfileFindDriver, which acts like a "for loop that avoids recursive function calls.

Example 1: Searching using the CFileFindDriver class
// Search for all .EXE and .DLL files on the C: drive
CStringArray sFileSpecArray;
sFileSpecArray.SetSize(2);
sFileSpecArray.SetAt(0, _T("*.EXE"));
sFileSpecArray.SetAt(1, _T("*.DLL"));
// TRUE = recurse into subdirectories
for (CFileFindDriver driver(_T("C:\\"), sFileSpecArray, TRUE);
driver.GetFileFind(); driver++)
{
// Retrieve fully qualified path of the .EXE or .DLL file
CString sFilePath(driver.GetFileFind()->GetFilePath());
// Retrieve file length
DWORD dwLength = driver.GetFileFind()->GetLength();
// Retrieve file creation date/time
CTime tmCreation;
driver.GetFileFind()->GetCreationTime(tmCreation);
etc.
}
