how to build a txt file and write the results in?
 

Hi,everyone could you tell me how to build a .txt file and write the results calculated into this file using UDF codes? what i used were:

fp=fopen("e:\\1f.txt", "w"); fprintf(fp, "%10d, %10d, %10d, %10d\n", count6, acc6, Ad6, Av6);

but nothing were writen to 1f.txt,i don't know what's wrong with it .
