[RESOLVED] Drawing a rubber band rectangle

[Zulfi Khan2]

Hi,
I am trying to draw a rubber band rectangle. I have got a following code from a site but its giving an error:

class CSampleView: Public CView

{

...

public:

CrectTracker m_tracker;//Changed to CRectTracker

...

};

Secondly, in the constructor to initialize the object CRectTracker document class:

CSampleDoc :: CSampleDOC ()

{

// Initialize tracker position, size and style.

m_tracker.m_rect.SetRect (0, 0, 10, 10);

m_tracker.m_nStyle = CRectTracker :: resizeInside |

CRectTracker :: dottedLine;

}

The error is:

error C2065: 'm_tracker' : undeclared identifier

Can some body please guide me how to get rid of this error??

Zulfi.
