Extracting part of a text

• (As already suggest) Use a pattern matching library, like a regular expression parser (google for a free C++ library).
• Use simple CString methods like Tokenize[^].
• Parse yourself the string for such patterns (you would have some fun with this approach...).

#include <vector>
#include <sstream>
#include <iterator>
#include <algorithm>
// ...
int indexValue = m_listItem.GetCursel();
CString strText;
m_listItem.GetText(indexValue, strText);

std::vector<std::string> parts;
std::istringstream iss(strText.GetBuffer());
std::copy(std::istream_iterator<std::string>(iss), std::istream_iterator<std::string>(), std::back_inserter(parts));

BOOL GetSubStringByIndex(int iIndexValue, int iSubstring, LPTSTR cpRetval)
{
  TCHAR caBuf[512];
  *cpRetval = 0;
  int iOffset = 0;

  m_listItem.GetText(indexValue,caBuf);

  caBuf[_tcslen(caBuf)+1] = 0; // double null terminate.
  LPTSTR cpSeg = caBuf;
  while (*cpSeg)
    {
      if (*cpSeg == ' ')
        *cpSeg = 0;
      cpSeg++;
    }

  // now, you can loop through them
  cpSeg = caBuf;
  while (*cpSeg)
    {
      if (iOffset == iSubstring)
        {
          _tcscpy(cpRetval,cpSeg);
          return TRUE;
        }

      cpSeg += _tcslen(cpSeg)+1;
      iOffset++;
    }

  return FALSE;
}
