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.

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...

I am begining to see that CString is a "C" string
Thanks

Well, most data comes down to being bytes... strings just are some set of bytes that are expected to mean something (whether according to ASCII or some other wide character standard)... if you need a generic container, you can't just use something that expects what we'd refer to as a "string".

Hi there, I am new to the programming scene. I am a Digital Forensic Investigator with the Digital Forensic Laboratory at The Directorate For Priority Crime Investigation; within the South African Police Services.
I was recently assigned to do research and analysis on compromised Verifone POS-devices. On some of the devices we do manage to extract data, which is encrypted. I investigated some of the tools the criminals use in the process.
On the malwr.com site the encryption tool PasswordGenerator.exe was uploaded and can be downloaded from there for analysis. This tool uses MACTripleDES PADRight encryption.
Is there maybe anyone that can assist me to create a tool to decrypt the data from the devices. The PWG creates an init.dat file that is uploaded to the POS device which encrypts the data that is captured and then decrypted after being downloaded with The VeriFoneDownloader.exe and then the .vfd-file is decrypted using the VeryFoneViewDataNew.exe. When the correct password is entered and the file decrypted it is saved as a .dfv-file.
All the .exe files are uploaded at malwr.com. I will upload an encrypted and decrypted file as well. (201404221348.vfd and 201404221348.dfv)
If there is anyone that can assist it would be highly appreciated.
