一、在不使用mfc的程序中获得某个目录下的所有文件名称,包括子目录。把文件名称以一个固定的程度放入一个缓冲中,这个缓冲要足够的大,能容下所有的文件名称。

函数的输入为要查找的根目录,输出为存放所有文件名称的缓冲

算法:使用递归
二、代码:

void FindFileInDir(char* rootDir, char* strRet)

{

    char fname[MAC_FILENAMELENOPATH];

    ZeroMemory(fname, MAC_FILENAMELENOPATH);

XML:namespace prefix = o ns = "urn:schemas-microsoft-com:Office:office" /> 

    WIN32_FIND_DATA fd;

    ZeroMemory(&fd, sizeof(WIN32_FIND_DATA));

 

    HANDLE hSearch;

    char filePathName[256];

    char tmpPath[256];

    ZeroMemory(filePathName, 256);

    ZeroMemory(tmpPath, 256);

 

    strcpy(filePathName, rootDir);

 

    BOOL bSearchFinished = FALSE;

 

    if( filePathName[strlen(filePathName) -1] != '""' )

    {

       strcat(filePathName, """");

    }

 

    strcat(filePathName, "*");

 

    hSearch = FindFirstFile(filePathName, &fd);

 

    //Is directory

    if( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)

       && strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") )      

    {

       strcpy(tmpPath, rootDir);

       strcat(tmpPath, fd.cFileName);

       FindFileInDir(tmpPath, strRet);

    }

   

    else   if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") )

              {

                  sprintf(fname, "%-50.50s", fd.cFileName);

                  strcat(strRet + strRet[strlen(strRet)] , fname);

              }

 

    while( !bSearchFinished )

    {

       if( FindNextFile(hSearch, &fd) )

       {

           if( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)

              && strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") )      

           {

              strcpy(tmpPath, rootDir);

              strcat(tmpPath, fd.cFileName);

              FindFileInDir(tmpPath, strRet);

           }

   

           else   if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") )

                     {

                         sprintf(fname, "%-50.50s", fd.cFileName);

                         strcat(strRet + strRet[strlen(strRet)] , fname);

                     }

       }

       else

       {

           if( GetLastError() == ERROR_NO_MORE_FILES )          //Normal Finished

           {

              bSearchFinished = TRUE;

           }

           else

              bSearchFinished = TRUE;     //Terminate Search

       }

    }

 

    FindClose(hSearch);

   

}
