[MFC] Refreshing Picture Control

[Skizmo]

You can pass the pointer of 1 class to another.

Something like this...

class A
{
public:

   int MyVariable;

};



class B
{
public:

  A *MyA;
  
  void SomeFunction ()
  {
      MyA->MyVariable = 10;
  }

};



int main ()
{
  A varA;
  B varB;

  varB.MyA = &varA;                 // set the pointer of varA
  varB.SomeFunction ();             // this function uses the varA-pointer to set MyVariable

};
