-
you have been very helpfull to me and believe it or not im so close to finish the first exercise of the project as you adviced I will study the materials again but it will be after I will hand it out because I have left a few more hours to work on it till it hits 11:50 pm
im sorry to bother you again but my time is not very short and I have no where else to go I combined the 2 codes i made into 1 but i keep getting now an error on the first function on the while How do i fix it? http://pastebin.com/p52qeXix[^]

well.. im trying to open a folder with an unknown number of programs using argv and argc through the cmd to the adress of the folder i need to use the dirent.h and maybe the FILE struct to open the files the code needs to open each file and search the text within (it has mp3 signatures etc) in a binary way and search through it with a second file that the text inside of it is not in any place in there in other words i need to spot if the second file's signature is nto repeatign anywhere on the other files this is the far that i got but im stuck can anyone help me?
#include <stdio.h>
#include <stdlib.h>
#include "dirent.h"int main(int argc, char** argv){
int count = 0, size = 0; int sizes\[3\]; FILE \*log = fopen("C:\\\\Users\\\\win7\\\\Desktop\\\\1\\\\C2\_Mid\_Anti-Virus\_Project.zip\\\\AntiVirusLog.txt", "wt"); DIR \*dir; struct dirent \*ent; int found = 0; /\* Open directory \*/ dir = opendir(argv\[1\]); while ((ent = readdir(dir))) { count++; sizes\[0\] = strlen(argv\[1\]); sizes\[1\] = 2; sizes\[2\] = strlen(ent->d\_name); size += sizes\[0\] + sizes\[1\] + sizes\[2\] + 1; char\* string = (char\*)malloc(sizeof(char)\*size); \_flushall(); strcpy(string,argv\[1\]); strcat(string, "\\\\"); strcat(string, ent->d\_name); FILE\* youtube = fopen (string, "rb"); if (youtube != NULL) { print("success \\n"); } puts(ent->d\_name); } fclose(log); closedir(dir); return 0;}

You mean files?

So what is your code (not) doing? Be specific, as "im stuck" is all sorts of vague.

thank you but atm im trying to figure out how to open the folder that contains the folder that I entered in argv because its a fodler inside a folder that contains files as you can see it doesnt work int count = 0, size = 0, totalDirs = 0,location = 0; int sizes[3],flag = 0; int secSpot = 0; int argvSize, spot = 0; char c; argvSize = strlen(argv[1]); for (int i = 0; i < argvSize; i++) { if (argv[1][i] == '/') { spot++; } } for (int i = 0; i < argvSize; i++) { if (argv[1][i] == '/') { if (secSpot != spot) { secSpot++; } else if ((secSpot == spot) && (flag == 0)) { location = i; flag++; } } } location--; char* entrenceToTheFolderBefore = (char*)malloc(sizeof(char)*location); for (int i = 0; i < location; i++) { entrenceToTheFolderBefore[i] = argv[1][i]; } puts(entrenceToTheFolderBefore); free(entrenceToTheFolderBefore);

Which would be that folder's parent. I'm not sure that is what you really want to do. :confused:

insteadof entering "\\" my teacher told me that I could use / to make it quicker my problem is tho that when I do puts i get garbage and not the output i wanted as a link outside of the argv folder

Perhaps one of you did not understand the other. Whether you use one character or two, the difference in time cannot be measured.

Nothing personal, but this code looks all kinds of convoluted. When iterating the items in the folder pointed to by
argv[1], how are you determining if an item is a file or a folder? [edit] Upon further inspection, I now see that code indirent.his a wrapper for this. My bad. [/edit] I suspect you need to be using the_findfirst()/_findnext()pair, or_stat()at the very minimum. It's been ages since I've used the former, but I envision something like:void processFile( const char *pFile )
{
// however you need to handle 'pFile' would go here
}//====================================================================
void processFolder( const char *pFolder )
{
char *p = (char *) malloc(strlen(pFolder) + 5);
strcpy(p, pFolder);
strcat(p, "\\*.*");struct \_finddata\_t fileinfo; intptr\_t handle = \_findfirst(p, &fileinfo); if (handle != -1) { do { if (fileinfo.attrib & \_A\_SUBDIR) { if (fileinfo.name\[0\] != '.') processFolder(fileinfo.name); } else processFile(fileinfo.name); } while(\_findnext(handle, &fileinfo) == 0); \_findclose(handle); } free(p);}
//====================================================================
void main(int argc, char* argv[])
{
if (argc == 2)
processFolder(argv[1]);
}Obviously this does not solve your overall problem, but you can't bother with checking the contents of a file before you have successfully iterated a folder.
