Are you using Excel's COM interface (i.e., automation), or its ODBC driver?

So what's the problem? Are you using GetDateFormat()?

Is it better to use a class or struct in this case?

I'm implementing a class to manage an array of objects created on the heap.. Something like:

class Manager {
public:
     Manager(void);
     ~Manager(void);
     Populate(LPVOID data);
     Retreive(int index);
private:
     myObject * objects;
     int count;
}

myObject needs to contain a char array and a BYTE array, both also on the heap. My first inclination was to use a STRUCT:

struct myObject {
     char * szName;
     byte * lpbData;
};

As I thought about it, though, it seemed memory clean-up would be easier if I made myObject a class with public members, initialize the values with a constructor, and let the destructor handle memory clean-up:

class myObject {
public:
myObject(char * name, BYTE * data, DWORD size) { 
     this->szName = new char[strlen(name)+1]; strcpy(this->szName, name, strlen(name);
     this->lpbData = new BYTE[size]; memcpy(this->lpbData, data, size);
     this->dwSize = size;
}
~myObject(void) { delete this->szName; delete this->lpbData; }
public:
     char * szName;
     BYTE * lpbData;
     DWORD dwSize;
};

Performance is critical in this particular application, and I'm thinking there's probably more to consider in the class vs. struct than just what makes memory cleanup easiest for me in the other classes.

Can anybody offer some help, here, or point me in the direction of a reference that might help?

Thanks,
MZR

classes and structs are basically the same in C++. The only difference is that structs have default member accessibility public, while classes have private.

Also, inheritance is public by default for structs and private by default for classes.

One could argue that they have "semantic" differences.

struct could be used to hold only data and class could be used to hold data and "behavior".

Yes, but this is left to the developer. In other words, C++ doesn't need structs at all, it still has for compatibility with C.

C++ neither needs macros (amongst other things), but for the sake of 'C' perverts like you, it had to be included. Smile | :)

On the other hand C needs none of the C++ sissy features. Poke tongue | ;-P

And Klingons programmers needs no postfix increment operator on their third variable.

You're wrong. Klingons keep C as their, not third, but umm... something like 18th variable to confuse the enemies. Poke tongue | ;-P

Good point. Anyway you're wrong as well, since Klingons never use more than five variables.
