the match value

[yh]

hi markc! first thanks!
I download the c++ demo then running the program but can't get the match values,why?
eg:
trd.GetInfo(TRID_GET_RES_POINTS, i, buf);
printf("Matching points: %s\n\n", ret);
printf:
matching points  n
I want to get the percent:
%55 <.JPG> JFIF-EXIF....
%33.3
my english is bad ,i hope you can understand and help me.

Hi!

Let's see if I understand correctly (my English isn't top notch too, so... ).

You mean you get the value / points, but you want the percentage also?
That's easy. The percentage is simply the incidence of one result to the sum of points of all results.
So, if you get 3 results like:

Filetype A 5000
Filetype B 2500
Filetype C 2500

The percentages would be, respectively, 50%, 25%, 25%.

Hope this helps,
Bye!

Hi mark0!  Thanks for your fast response and your effort!
I know  my problem.
--   in the c++ demo
ret = trd.GetInfo(TRID_GET_RES_NUM,0,buf);
for(int i = ret+1; --i;)
{
      trd.GetInfo(TRID_GET_RES_FILETYPE,i,buf);
      printf("File type: %s\n",buf);
      trd.GetInfo(TRID_GET_RES_FILEEXT,i,buf);;
     printf("File ext: .%s\n",buf);
     trd.GetInfo(TRID_GET_RES_POINTS,i,buf);
     printf("Matching points: %d\n\n",ret);     // I think  this is a bug . Because the "ret"  always equal  "trd.GetInfo(TRID_GET_RES_NUM,0,buf)"
                                                                // So i can't get the  right match values.
}

match = trd.GetInfo(TRID_GET_RES_POINTS,i,buf);
printf("Matching points: %d\n\n",match);   //  This code can print  the right match values.

I have not much experience in C++, and the sample source was kindly provided by another user.
Indeed a var assignment is missing in the last call to trd.GetInfo.
I will update the sample code.

Thanks,
Bye!
