Use PathRemoveFileSpec() or _splitpath().

You might want to consider strrchr() to find the last backslash. Put a '\0' character there.

see here

and also try with the David crow's recent post that would be easier than mine.

you're right:

const char * path ="/work1/data/xxxx/yyy/file_name.txt";
char * basename;
char * filename;

basename = _strdup(path);
if ( !basename){/*handle error*/}


filename = basename+strlen(basename);

while (filename != basename && *(filename) != '/')
  filename--;

if ( filename != basename)
{
  *(filename+1)='\0';
}
else
  *basename='\0';

printf("%s\n", basename);
free(basename); /* REMEMBER TO FREE */

Why would this cause a class destruction crashed?

Hi

I have a class like:

class CMyclass1
{
public

CMyclass2 myclass; 

.....
}

class CMyclass2
{
public

TCHAR Var[SOMEVALUE]; 

.....
}

CMyclass2 ::CMyclass2
{
 memset(Var, '\0',sizeof(Var));
 strcpy_s(Var,"some value");

}

----------- When I did following, program crashed ---
CMyclass1 * pclass = new CMyclass1()
delete pclass;

How can fix this problem?

Best regards,

There are 2 reasons:-
1. If you give SOMEVALUE=3 and copy "some value" it will fail and program will crash, so please check that.
2. what is need of memset when you are allocating in a stack?, Doing this also fails.
So handle heap allocation carefully. Smile | :)

Hi

I did following:

#define SOMEVALUE 100

Why this will cause problem?

I used "memset" to initialize the array. What else can I use to initialize an array?

So "memset" will use HEAP? I deleted the "memset", the bug is still there.

Best regards,

Use the debugger to step through the code to find the offending line. Aside from some syntax errors, your code works fine with VS6.

Using memset() is fine, although unnecessary in the context in which you are using it.

I did following to solve the problem.

class CMyclass2
{
public

TCHAR* Var; 

.....
}

CMyclass2::CMyclass2
{

 Var =  new TCHAR[SOMEVALUE];

}

VC++ does not allow TCHAR array in a class definition? Actually, TCHAR array is a pointer.

Sure it does.

It is now, but it wasn't earlier.

Hi
Why it crashes when I use TCHAR array in the class definition and it works just fine when I use TCHAR pointer?

Thanks,
