    string pointers

    Hi,

    I'm trying to use string pointers within a class, but when I run de-bugger, I get an access violation from the line where I initialize the object. Here is a shortened version of my class:

    class Employee
    {
    string *sName;
    string *sNumber;
    public:
    Employee()
    {
    *sName = "Doe, John"; // access violation
    *sNumber = "0000"; // This would be too, but
    } // don't get this far.
    };

    Thanks,
    David

    you have to allocate memory for the strings before you can assign values...ex:

    string *myString; //declare point to a string
    myString = new string; //allocate memory in heap
    *myString = "Hello, World!"; //assign
    My Website

    you need to allocated memory to the pointer... also, after it's declaration, you cannot store the string into the memory allocated into the pointer like that, you'd have to do it 'by hand'... accessing and assigning each element of the array...
