Your GetDlgItem call is useless and wrong.
You are set a empty string always to textbox.
Use WM_SETTEXT, SetWindowText or SetDlgItemText, how you wish ...
Ch1156 (2010)
So it would be something like:

1
2
 
char tmp[WM_SETTEXT+1] = {0};
SetWindowText(hwndDlg, 1, tmp, WM_SETTEXT);

  case one:
  {
    SetDlgItemText(hwndDlg,one,text); // text would be a cstring defined somewhere else in this case
  } break;


If `text` happened to be a std::string instead of cstring you could also do: SetDlgItemText(hwndDlg,one,text.c_str());
