Why is “operator bool()” invoked when I cast to “long”?

Question

I have the following class:

class MyClass {
public:
   MyClass( char* what ) : controlled( what ) {}
   ~MyClass() { delete[] controlled; }
   operator char*() c         


        

Answer 1

You cannot implicitly cast a T* to long. But you can cast a bool to long.

So the operator bool is used.

You have to define a operator LPARAM.
