void CMyReadFile::split(LPCTSTR szString, TCHAR chrPattern, CStringArray &csString)
{
 
        // Pointer to find separate string, spacer by chrPattern
        TCHAR szBuffer[1024] = {0};
        LPCTSTR pFirst, pNext;
 
        // Empty buffer
        csString.RemoveAll();
 
        // Pointed to ahead
        pFirst = szString;
 
        // Find the pattern to separate each string
        while (pFirst && lstrlen(pFirst))
        {
                    pNext = StrChr(pFirst, chrPattern);
                    if (pNext)
                    {
                                lstrcpyn(szBuffer, pFirst, pNext - pFirst + 1);
                                pFirst = pNext + 1;
                    }
                    else
                    {
                                lstrcpy(szBuffer, pFirst);
                                pFirst = pNext;
                    }
 
                    // Add to list
                    csString.Add(szBuffer);
        }
 
}

Using Function:

void CDemoAPIDlg::OnBnClickedButtonShow()
{
   // TODO: Add your control notification handler code here
 
   wchar_t szPathToExe[MAX_PATH];
   GetModuleFileNameW(NULL, szPathToExe, MAX_PATH);

   PathRemoveFileSpec(szPathToExe); 
 
   CString szPathToFile = (CString)szPathToExe +  L"\\test.txt";
   CString szTemp = CMyReadFile::readFileText(szPathToFile);

   CStringArray csString;
   CMyReadFile::split(szTemp, L'\r\n', csString);

   for (int i=0; i<csString.GetCount(); i++)
        AfxMessageBox(csString[i]);
 
}

On this tutorial, I have Read File Text function. This function I had showed on this topic.
