Hi, The following C code, at present does the following :- Takes the Output file name from character 1 of the input filename (ALLSMFAS.ref) and creates a new file (A.brt) as follows :- ALLSMFAS.ref ----------------- AD,B,0424,0415,89375,,A,2,,80,, AD,B,0424,0417,89375,,A,1,,82,, AD,B,0416,0410,89375,,B,2,,-7,2, BN,B,0135,0094,65625,,D,,,0,1,H BN,B,0338,0337,65824,,B,,,-18,1, BN,B,0334,0339,65824,,C,,,65,, CA,T,,SREC,47221,,C,,R,0,, CA,T,,X171,47221,,A,6,,60,, CA,T,,X173,47221,,A,5,,60,, CC,B,1783,1574,48231,,C,1,,60,, CC,B,1783,1576,48231,,C,2,,60,, CC,B,1783,1578,48231,,C,3,,60,, A.brt ------ B0424041589375 B0424041789375 B0416041089375 B0135009465625 B0338033765824 B0334033965824 T SREC47221 T X17147221 T X17347221 B1783157448231 B1783157648231 B1783157848231 But now,I want to modify the above program to read each value of column 1 of my input file (ALLSMFAS.ref) and create Output file with name as the value at the column 1 of the input file. For each change in the value at column 1 of input file, a new output file should be created, as follows :- ALLSMFAS.ref ---------------- AD,B,0424,0415,89375,,A,2,,80,, AD,B,0424,0417,89375,,A,1,,82,, AD,B,0416,0410,89375,,B,2,,-7,2, BN,B,0135,0094,65625,,D,,,0,1,H BN,B,0338,0337,65824,,B,,,-18,1, BN,B,0334,0339,65824,,C,,,65,, CA,T,,SREC,47221,,C,,R,0,, CA,T,,X171,47221,,A,6,,60,, CA,T,,X173,47221,,A,5,,60,, CC,B,1783,1574,48231,,C,1,,60,, CC,B,1783,1576,48231,,C,2,,60,, CC,B,1783,1578,48231,,C,3,,60,, : : and so on.. the following are the output files. AD.brt -------- B0424041589375 B0424041789375 B0416041089375 BN.brt -------- B0135009465625 B0338033765824 B0334033965824 CA.brt -------- T SREC47221 T X17147221 T X17347221 CC.brt -------- B1783157448231 B1783157648231 B1783157848231 and so on .... The logic for taking the output filename name from character 1 of the input filename is as below :- Code: // Take the brt file name from character 1 of the input filename. memcpy(this_td, wfd.cFileName, 1); this_td[2] = 0; I think I have to change at this place so that the code reads each value of column 1 of my input file (ALLSMFAS.ref) and create Output file with name as the value at the column 1 of the input file. For each change in the value at column 1 of input file, a new output file is created. I am unable to proceed further to implement this. Request you, if you could please help me on this.

Seems to be a duplicate of another thread http://www.go4expert.com/showthread.php?t=19094 Why doesn't my response in that thread help you? Are you simply looking for someone to write the code for you or do you want help solving the problem yourself?

Hi, I modified my above program with the following code to read each value of column 1 of my input file (*.ref) and create multiple Output files (*.brt) with name as the value at the column 1 of the input file. For each change in the value at column 1 of input file, a new output file (*.brt) should be created. But it doesn't seem to work. Could you please help me with the changes to the following code so that it works. I already seem to have messed up on this Trivial change :- Code: // Take the output file names (*.brt) from column 1 of the data of the input file (*.ref). // New output file created for each change in the value of the first column of the // input file. f_name[12] = fgetc(ref_file); f_name[13] = fgetc(ref_file); f_name[14] = '.'; f_name[15] = 'r'; f_name[16] = 'e'; f_name[17] = 'f'; f_name[18] = 0; fgetc(ref_file); while(!feof(ref_file)) { ch = fgetc(ref_file); // brt_file = fopen(f_name, "a"); commaCount = 0; } while(ch != newline && commaCount < 4) { if (ch == ',') { commaCount ++; } else { //fputc(ch,brt_file); ch = fgetc(ref_file); } } //fputc(' ',brt_file); //flush rest of line while(ch != newline ) { ch = fgetc(ref_file); } //fclose(brt_file); //f_name[12]=fgetc(brt_file); //f_name[13]=fgetc(brt_file); //f_name[14]= '.'; //f_name[15]='b'; //f_name[12]='r'; //f_name[12]='t'; //f_name[12]=0; //fgetc(brt_file); //} //return 0 ; Thanks a lot.
