_splitpath() is better option.

You may use PathFindFileName() like this:
TCHAR *szPath = _T("C:\\Program Files\\codeproject.txt");
AfxMessageBox(PathFindFileName(szPath));

Hi,
char szFilePath[MAX_PATH] = {"C:\\Program Files\\codeproject.txt"};
char szFileNameOnly = strrchr(szFilePath,'\\');
if(szFileNameOnly)
szFileNameOnly++;
now szFileName points to "codeproject.txt"
i think this works fine for u.

Good, but a small correction. strrchr returns a character pointer.

When you drag a URL from within a browser onto a windows explorer folder windows explorer creates .URL file that has the same name as what is displayed if you were to bookmark the URL. The contents of the .URL file contains the iconfile and iconindex which are somehow gotten by connecting to the URL link. What APIs are available to retrieve this information?

Do you know which pin does what on the motor (e.g., pin 1 is on, pin 2 is off, pin 3 is forward, pin 4 is reverse)?

i got some information, but finding it was very hard.
it has six wires. two reds, two yellows and two grey.
Grey1 --- --- Grey2
¦ ¦
¦ ¦
Red1 --- --- Red1 (reds are common)
¦ ¦
¦ ¦
Yellow1 --- --- Yellow2
i cannot understand which wire has to be connect to the uln's first output and second etc.
thanks for your answer.

I'm having trouble with vtables. I have a class:
class CLatticeNode {
public:
CLatticeNode(void);
virtual ~CLatticeNode(void);
CLatticeNode(double SpotPrice) {
m_dUnderlyingPrice = SpotPrice;
m_dOptionValue = 0.0;
};
inline double GetUnderlyingPrice(void) const { return this->m_dUnderlyingPrice; };
inline double GetOptionValue(void) const { return this->m_dOptionValue; };
inline void SetUnderlyingPrice(double Price) { m_dUnderlyingPrice = Price; };
inline void SetOptionValue(double Value) { m_dOptionValue = Value; };
private:
double m_dUnderlyingPrice;
double m_dOptionValue;
};
I have a std::vector of boost pointers declared as follows:
typedef boost::shared_ptr <CLatticeNode> CLatticeNodePtr;
and a vector of vectors:
std::vector< std::vector<CLatticeNodePtr> > Tree;
I'm trying to call the member function GetUnderlyingPrice as follows:
Tree[col].push_back(CLatticeNodePtr(new CLatticeNode((Tree[col-1][row])->GetUnderlyingPrice() * m_dU)));
Basically I'm trying to access the CLatticeNode member function GetUnderlyingPrice via
the call:
Tree[col-1][row]->GetUnderlyingPrice()
But on compile, I consistently get:
g++ -L/usr/local/boost-1.34.1 -o "AMMPricer" ./AMMPricer.o ./LatticeClass.o ./TrinomialTree.o
/usr/bin/ld: Undefined symbols:
vtable for CLatticeNode
collect2: ld returned 1 exit status
make: *** [AMMPricer] Error 1
Is this a linker error or have I got something wrong in the class definition?

If you spit those line, will that work ? or does that give you some other error/warnings ?
can you test your code with Visual Studio compiler ?

Yes, I've tried splitting them and I get the same problem. This code is in a unix environment - I don't have the ability (or the time) to port it to VS. The vtable problem is usually a linker error, but I suspect there's something wrong with the class definition. I can't see what it is though.

Seriously, have you tried this without using the boost shared ptr? If that works then maybe it's the way you're using the smart pointer? I would try and break up that single line statement into *all* it's component parts and see if there's something weird going on there.
One other thought - do you implement the default constructor? You don't have any impl here, maybe that's the problem?

I have tried breaking it up into a million little pieces, but I consistently get the vtable error. That's why I called this thread "VTable Madness". It's driving me insane.

Hmmmmm, it should be in there. If not, I've done it like this in the .h file:
CLatticeNode(void) {;};

Found it! Not the CONSTRUCTOR, but the virtual DESTRUCTOR wasn't implemented. Gah!

Awesome! I think I've seen a similar kind of error with VC 6, only it's occurs in the compile phase as opposed to the linking phase.

I'm having trouble finding a c or c++ function that will convert a string of 1's and 0's to a string of characters. I also need something that will do the opposite. I was just wondering if there is a class out there that will handle this. I really don't feel like writing my own, if I can find one that will do it for me.

Assuming you meant to its numeric equivalent, check out strtol().

There are plenty available (e.g., CP, Google), but writing your own will take all of five minutes. You'll spend more time than that searching (and then implementing).

Ok, four minutes if you don't do any simultaneous browsing or game-playing.
