Answer 1

 CString strFull,CString strHalf;
 const char *pszFull=strFull.GetBuffer(strFull.GetLength());
 int npszFull=strlen(pszFull); char* pszHalf=new char[npszFull+1];
 memset(pszHalf,0,npszFull+1); int iHalf=0,iFull=0;
 for(int iFull=0;iFull<npszFull;)
 {
  if((BYTE)(pszFull[iFull])<128)//半角
  {
  memcpy(pszHalf+iHalf,pszFull+iFull,1);
  iHalf++;
  iFull++;
  }
  else//全角
  {
  BYTE bTemp=BYTE(pszFull[iFull+1]);
  char cTemp=bTemp-128;
  memcpy(pszHalf+iHalf,&cTemp,1);
  iHalf++;
  iFull++;
  iFull++;
  }
 }
