I will soon be providing an update to this article that is a new implementation using my new CGCMultiFieldEdit class (see the article "Multi-Field Edit Controls -- A Whole New Class of Edit Controls"). This is a better implementation that will be easier to modify for future capabilities and styles. Look for it soon!

Two new methods: SetDecimalDegrees

Hi,

first of all great source!!!

However, in addition to the method GetDecimalDegrees

I missed the opposite method SetDecimalDegrees.

So here it is. Just add the following code:

GECLongitudeCtrl.h

==================

BOOL CGCLongitudeCtrl::SetDecimalDegrees(const double dDegrees);



GECLongitudeCtrl.cpp 

====================

BOOL CGCLongitudeCtrl::SetDecimalDegrees(const double dDegrees)

{

  double tmpval = dDegrees;

  if ((dDegrees < -180.0) || (dDegrees > 180.0))

  {

    return false;

  }

  if (dDegrees < 0)

  {

    m_Hemisphere = W;

  }

  else

  {

    m_Hemisphere = E;

  }

  m_iDegrees = (int) tmpval;

  tmpval    -= m_iDegrees;

  m_iMinutes = ((int) (3600.0 * tmpval)) / 60;

  m_fSeconds = (3600.0 * tmpval) - m_iMinutes * 60;

  FormatAndDisplay();

  return true;

}



GECLatitudeCtrl.h

==================

BOOL CGCLatitudeCtrl::SetDecimalDegrees(const double dDegrees);



GECLatitudeCtrl.cpp 

===================

BOOL CGCLatitudeCtrl::SetDecimalDegrees(const double dDegrees)

{

  double tmpval = dDegrees;

  if ((dDegrees < -90.0) || (dDegrees > 90.0))

  {

    return false;

  }

  if (dDegrees < 0)

  {

    m_Hemisphere = S;

  }

  else

  {

    m_Hemisphere = N;

  }

  m_iDegrees = (int) tmpval;

  tmpval    -= m_iDegrees;

  m_iMinutes = ((int) (3600.0 * tmpval)) / 60;

  m_fSeconds = (3600.0 * tmpval) - m_iMinutes * 60;

  FormatAndDisplay();

  return true;

}



Have fun,

Ciao Roland :)

Very Cool Code

This is a class piece of work and thanks for sharing it with us. Can u generalize this for all the geographic co-ordinate systems, like one base class for the mouse an edit window handling an char tracking, but allow virtuals for all the other implementations. Thanks again , your coding style is very professional also clear and concise. [:-)]
