Solution 2

Use GetLine(int nIndex,LPTSTR lpszBuffer) function to read specific line from Rich Textbox it will copy specified index line into buffer. To read whole line use GetLineCount() function which will return you the total no. of lines in Rich Textbox, using this make loop to read all lines.

Solution 3

Check your m_richctrl is valid window or not.Also, Where you are using control in dialog box or like a view in MainFrame.

You can do it in this way:

#include <Richedit.h>
unsigned int GetRichText(HWND hrich,int bRTF,TCHAR* buff,const unsigned int size)
{
  struct _
  {
    static unsigned int  copy(char* dst,unsigned int ndst,char* src,unsigned int nsrc)
      { unsigned int i; for(i=0;i<min(ndst,nsrc);i++) dst[i]=src[i]; dst[i<ndst?i:i-1]=0; return i; }
    static unsigned int  copy(unsigned short* dst,unsigned int ndst,unsigned short* src,unsigned int nsrc)
      { unsigned int i; for(i=0;i<min(ndst,nsrc);i++) dst[i]=src[i]; dst[i<ndst?i:i-1]=0; return i; }
  #ifdef _UNICODE
    static void  rtfW(unsigned long p,unsigned short* pbBuff,long cb,long* pcb)
      { _*me=(_*)p; me->done=copy(me->buff,me->size,pbBuff,cb); *pcb=cb; }
    static void  txtW(unsigned long p,unsigned short* pbBuff,long cb,long* pcb)
      { _*me=(_*)p; me->done=copy(me->buff,me->size,pbBuff,cb); *pcb=cb; }
  #else
    static void  rtfA(unsigned long p,char* pbBuff,long cb,long* pcb)
      { _*me=(_*)p; me->done=copy(me->buff,me->size,pbBuff,cb); *pcb=cb; }
    static void  txtA(unsigned long p,char* pbBuff,long cb,long* pcb)
      { _*me=(_*)p; me->done=copy(me->buff,me->size,pbBuff,cb); *pcb=cb; }
  #endif
    
    TCHAR*        buff;
    unsigned int  size;
    unsigned int  done;
  }             get = { buff,size,0 };
  EDITSTREAM    eds = { (DWORD_PTR)&get,0, };

  if(bRTF)
  {
  #ifdef _UNICODE
    eds.pfnCallback = (EDITSTREAMCALLBACK)get.rtfW;
    SendMessage(hrich,EM_STREAMOUT,SF_RTF|SF_UNICODE,(LPARAM)&eds);
  #else
    eds.pfnCallback = (EDITSTREAMCALLBACK)get.rtfA;
    SendMessage(hrich,EM_STREAMOUT,SF_RTF,(LPARAM)&eds);
  #endif
  }
  else
  {
  #ifdef _UNICODE
    eds.pfnCallback = (EDITSTREAMCALLBACK)get.txtW;
    SendMessage(hrich,EM_STREAMOUT,SF_TEXT|SF_UNICODE,(LPARAM)&eds);
  #else
    eds.pfnCallback = (EDITSTREAMCALLBACK)get.txtA;
    SendMessage(hrich,EM_STREAMOUT,SF_TEXT,(LPARAM)&eds);
  #endif
  }
  return get.done;
}

Regards.
