no i want to assign the value of the variable in the other class to m_sNumber.

Can someone PLEASE give me the necessary code to retrieve the value of a member variable from another class! Maybe then I'll understand it.

class ClassA
{
public:
ClassA()
{
m_number = 5;
}
int m_number;
}
class ClassB
{
public:
ClassB()
{
theint = -1;
}
void GetANum(ClassA *ClassPointer);
int theint;
}

ClassB::GetANum(ClassA *ClassPointer)
{
theint = ClassPointer->m_number;
}

main()
{
ClassA MyClassA;
ClassB MyClassB;

MyClassB.GetANum(&MyClassA);

printf("%d", MyClassB.theint);
}


Obviously this is psuedocode and won't compile, but it gets the point across I think. It would print the number 5 assuming that it had the proper includes, etc.

You really should read more about pointers, they are one of the harder concepts to grasp.
