Can we use MFC and wxWidgets at the same time in Windows environment? I tried to do the following in my code


  1. include <Afxwin.h>
  2. include <Afxtempl.h>

// For compilers that support precompilation, includes "wx.h".

  1. include <wx/wxprec.h>
  2. ifdef __BORLANDC__
  3. pragma hdrstop
  4. endif
  1. ifndef WX_PRECOMP

// Include your minimal set of headers here, or wx.h

  1. include <wx/wx.h>
  2. endif
  1. include "wx/dynarray.h"

.... </nowiki>

THen I tried to do the following

WX_DEFINE_ARRAY_INT(int, CChannel);

WX_DEFINE_ARRAY(CChannel *, CChannelArray);

void main()

{

//CArray <float,float> PCChannel;

int m_lNumChannels = 80;

int m_lNumTimeslices = 100;

CChannel *pChannel;

...

When I compile the code in VC++ 6, I got the following error. I am wondering if someone can help me with this issue. Thank you
