Make your own "vtkMyInteractorStyle" based on e.g. vtkInteractorStyleTrackballCamera.
Like this:

#include "vtkInteractorStyleTrackballCamera.h"

class vtkMyInteractorStyle : public vtkInteractorStyleTrackballCamera
{
public:
static vtkMyInteractorStyle *New();

void OnLeftButtonDown();
void OnLeftButtonUp();

protected:
vtkMyInteractorStyle();
};


vtkStandardNewMacro(vtkMyInteractorStyle);

vtkMyInteractorStyle::vtkMyInteractorStyle() : vtkInteractorStyleTrackballCamera()
{
}

void vtkMyInteractorStyle::OnLeftButtonDown()
{
  AfxMessageBox("left button down");
}
void vtkMyInteractorStyle::OnLeftButtonUp()
{
  AfxMessageBox("left button up");
}

Add the interactor to your renderer, like
m_pvtkWin32RenderWI->SetInteractorStyle(m_pvtkMyInteractorStyle);
