Hi,

I want to call a function from Class "A" in Class "B". Both of these classes are in the same header file.

C++

class ClassA: My own class
{
public:
  void OnMouseEvent(MouseEvent mouseEvent, CPoint point);
};

class ClassB: public CDialog
{
   void SetMinMax();
};

I've tried using:

C++

ClassB *dlg = (ClassB*) this->GetParent();

in the function "OnMouseEvent", But it gave me an:
"error C2039: 'GetParent' : is not a member of 'ClassA'

I need to call "SetMinMax() in OnMouseEvent().
Is there anyway to do it?

Thank you for helping.

Since there is no relationship between the two classes, and ClassA is not a Window class, you should put the OnMouseEvent() handler into ClassB.

How about this

C#

class ClassA: My own class
{
public:
  void OnMouseEvent(MouseEvent mouseEvent, CPoint point)
  {
      ClassB b;
      b.SetMinMax();
  }
};
 
class ClassB: public CDialog
{
   void SetMinMax();
};
