Hi I have a base Object class where in the constructor I pass in a device. My Line drawing class inherits from the object class. But I don't know how to code the constructor for it. It says the Object class constructor doesnt take 0 arguments.

if your using c++ it would look something like this

class A{	D* m_d;public:	A(D* d);};A::A(D* d){	m_d = d;}class B : public A{public:	B(D* d);	// or	B();};B::B(D* d) : A(d){	// do something here}// orB::B() : A(g_d) // g_d is a global pointer to a D{	// do something here}

Thanks, I am using c# though I figured it out, I just used b : base(d) and it works fine, thanks for the help
