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
|
|
|
|

it seems that the problem is within these lines
for (int i = 0; i < argvSize; i++)
{
if (argv[1][i] == '/')
{
if (secSpot != spot)
{
secSpot++;
}
if (secSpot == spot)
{
if (flag == 0)
{
location = i;
flag++;
}
}
}
}
_flushall();
char* entrenceToTheFolderBefore = (char*)malloc(sizeof(char)*location);
int a;
a = strlen(entrenceToTheFolderBefore);
printf("%d", a);
for (int i = 0; i < location; i++)
{
entrenceToTheFolderBefore[i] = argv[1][i];
}
when the entrenceToTheFolderBefore has the size of 40 bits and not 23 like it was suppsoe to
the argv that im using is C:/Users/win7/Desktop/1/C2_Mid_Anti - Virus_Project.zip

Sorry, but that code does not make any sense. I have no idea what the first block of code is supposed to be doing. And in the code following the flushall call, you have made a call to strlen on a pointer returned from malloc. But the memory that it points to has not been initialised with a string, so the value you get will be either zero, or some random invalid number. You must use strlen on the source string (argv[1]) in order to measure it. So your code should be something like:
int length = strlen(argv[1]) + 1; char* entrenceToTheFolderBefore = (char*)malloc(sizeof(char) * length);
for (int i = 0; i < length; i++)
{
entrenceToTheFolderBefore[i] = argv[1][i];
}
You could use strcpy here, but perhaps your teacher has told you not to.

I dont know if i fixed it or not because Just now i saw your comment
but this is how far i got in order to get to the second frole from the first file
but for some odd reason it stopps when i do malloc
#include <string.h>
#include <stdlib.h>
#include "dirent.h"
int main(int argc, char** argv)
{
DIR* OtherDir;
struct dirent *OtherEnt;
int location = 0, flag = 0, secSpot = 0, argvSize, spot = 0,i;
argvSize = strlen(argv[1]);
for (i = 0; i < argvSize; i++)
{
if (argv[1][i] == '/')
{
spot++;
}
}
puts(argv[1]);
for (i = 0; i < argvSize; i++)
{
if (argv[1][i] == '/')
{
if (secSpot != spot)
{
secSpot++;
}
if (secSpot == spot)
{
if (flag == 0)
{
location = i;
flag++;
}
}
}
}
char* UnwantedName = (char*)malloc(NULL); //<--- problem
for (int i = location + 1; i < argvSize; i++)
{
strcat(UnwantedName,"/C2_Mid_Anti-Virus_Project.zip");
}
_flushall();
char* entrenceToTheFolderBefore = (char*)malloc(sizeof(char)*location);
for (int i = 0; i < location; i++)
{
entrenceToTheFolderBefore[i] = argv[1][i];
}
_flushall();
OtherDir = opendir(entrenceToTheFolderBefore);
char* notPath1 = (char*)malloc(NULL);
char* notPath2 = (char*)malloc(NULL);
strcpy(notPath1, argv[1]);
strcpy(notPath2, argv[1]);
strcat(notPath1, "/.");
strcat(notPath2, "/..");
char* InfectedFolderPath = (char*)malloc(NULL);
while (OtherEnt = readdir(OtherDir))
{
if ((strcmp(OtherEnt->d_name, UnwantedName) != 0 && (strcmp(UnwantedName, notPath1) != 0) && (strcmp(UnwantedName, notPath2) != 0)))
{
strcpy(InfectedFolderPath, entrenceToTheFolderBefore);
strcat(InfectedFolderPath, "/");
strcat(InfectedFolderPath, OtherEnt->d_name);
puts(InfectedFolderPath);
}
}
free(UnwantedName);
free(entrenceToTheFolderBefore);
free(InfectedFolderPath);
free(notPath1);
free(notPath2);
}

It would help if you formatted your code properly with <pre> tags around it, and removed the extra blank lines.
The following is wrong, you cannot malloc nothing.
char* UnwantedName = (char*)malloc(NULL);
You must provide the size, in bytes, that you want to allocate, like
char* UnwantedName = (char*)malloc(argvSize);

I tried editing it to
char* entrenceToTheFolderBefore =(char*)malloc(sizeof(char)*location);
but it still triggers a break point
|
|
|
|
|
this is odd it seems that after switching place wit hthe malloc above it was ok

Go to ParentNow that I fixed most of the code the last part is which is the loop to find out the name of the second folder
Reminder that The argv has a path to a folder
the program is trying to exit the folder to the fodler before (succeeded)
and now at the last part trying to get the path for the second folder and the file before if it makes any sence
so for some odd reason it doesnt work
the weirder part is when i try to do puts(); on the Dir struct d_name
and it triggers break point
Hide Copy Code
//UnwatedName = /C2_Mid_Anti-Virus_Project.zip notPath1 = '.' notPath2=".."
while (OtherEnt = readdir(OtherDir))
{
puts(OtherEnt->d_name);
if ((OtherEnt->d_name != UnwantedName) && (OtherEnt->d_name != notPath1) && (OtherEnt->d_name != notPath2))
{
puts(OtherEnt->d_name);
strcpy(InfectedFolderPath, entrenceToTheFolderBefore);
strcat(InfectedFolderPath, "/");
strcat(InfectedFolderPath, OtherEnt->d_name);
puts(InfectedFolderPath);
}
}

You cannot use != to compare strings, you need to use strcmp.
If you are going to append a new directory name to an existing path then you need to allocate the sum of, the length of each string, plus 1 for the extra backslash, plus 1 for the trailing null.
I would strongly suggest you get some decent learning materials and study the basics of the C language and standard libraries, before continuing with this somewhat advanced project.

to be honest the first thing i used was strcmp i tried to do so many combinatiosn and in so many different ways that im out of ideas so i tried anything that could might help
|

That is what I guessed from looking at all your posts. And that is why I suggested you stop trying random pieces of code, and go and work through some tutorials and reference guides on the basics of C and its run-time libraries. Trying to learn programming from posting questions here is really not a good idea. A few, or many, hours of serious study will serve you much better in the long term.

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?

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

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

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 in dirent.h is 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 )
{
}
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)
{<br />
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.

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

Hi,
I have been having issues trying to use CString with non display characters e.g. X0A or nulls
I now there is a constructer CString(LPCTSTR,int) which takes a length the contructer
Doesn't take a pointer e.g. CString *mystr(str,20)
Any help would be appreciated
Thanks

What exactly are the issues you are having, your question does not make it clear.

The scenario is the following
I have a shared storage pointer with my console application Hercules it is defined as LPVOID most of it is displayable characters but some are just hex characters
When try to construct the string with the following CString constructer
CString mystr((LPCTSTR) mysharedptr,34); tracing it in the visual studio debugger
The code goes off into some MFC code that had an assertion specifically ASSERT(FALSE)
Thanks

Show the function and the ASSERT where it goes.
The difficult we do right away...
...the impossible takes slightly longer.
|
|
|
|
|
Sorry but you are still not giving us any useful information. What exactly is the content of mysharedptr, and what assertion are you getting? It may well be that a CString is just the wrong class for whatever problem you are trying to solve.

Richard
I had a religious holiday over the last 2 days
I do have non display hex characters in the CString
I am begining to think that even though there is a constructer for CString that takes a length it Still is just that a Csting a C type string
|

CString holds strings. C-type strings.
if you need a container to hold chunks of data which might contain a NULL, CString is the wrong container. you can use a std::vector< BYTE > (or a CByteArray, if you like MFC). or you can roll your own.
|
|
|
|
|
As Chris mentioned, think you're trying to use CString for something it's not intended to do. If you need a random byte container (that isn't a string), use something else.
STL has a quite a few to choose from[^].
Additionally, other libraries have other choices...
