Examples of errors detected by the V525…

Examples of errors detected by the V525 diagnostic

V525. Code contains collection of similar blocks. Check items X, Y, Z, ... in lines N1, N2, N3, ...


Win32++

V525 The code containing the collection of similar blocks. Check items 'OnFileOpen', 'OnFileSave', 'OnFileSave', 'OnFilePrint' in lines 37, 41, 45, 48. Frame mainfrm.cpp 37


BOOL CMainFrame::OnCommand(WPARAM wParam, LPARAM lParam)
{
  ....
  case IDM_FILE_OPEN:
    // Refer to the tutorial for an example of OnFileOpen
    OnFileOpen();
    return TRUE;
  case IDM_FILE_SAVE:
    // Refer to the tutorial for an example of OnFileSave
    OnFileSave();
    return TRUE;
  case IDM_FILE_SAVEAS:
    // Refer to the tutorial for an example of OnFileSaveAs
    OnFileSave();
    return TRUE;
  ....
}

Most likely this is what should be written here: case IDM_FILE_SAVEAS: OnFileSaveAs() ....


Fennec Media

V525 The code containing the collection of similar blocks. Check items '11', '12', '13', '13' in lines 716, 717, 718, 719. id3 editor.c 716


void* tag_write_setframe(char *tmem,
  const char *tid, const string dstr)
{
  ....
  if(lset)
  {
    fhead[11] = '\0';
    fhead[12] = '\0';
    fhead[13] = '\0';
    fhead[13] = '\0';
  }
  ....
}

Notepad++

V525 The code containing the collection of similar blocks. Check items '7', '7', '6', '7' in lines 576, 580, 584, 588


#define IDC_KEYWORD1_ITALIC_CHECK (IDC_KEYWORD1 + 7)
#define IDC_KEYWORD3_BOLD_CHECK (IDC_KEYWORD3 + 6)

void KeyWordsStyleDialog::updateDlg()
{
  ....
  Style & w1Style =
    _pUserLang->_styleArray.getStyler(STYLE_WORD1_INDEX);
  styleUpdate(w1Style, _pFgColour[0], _pBgColour[0],
    IDC_KEYWORD1_FONT_COMBO, IDC_KEYWORD1_FONTSIZE_COMBO,
    IDC_KEYWORD1_BOLD_CHECK, IDC_KEYWORD1_ITALIC_CHECK,
    IDC_KEYWORD1_UNDERLINE_CHECK);

  Style & w2Style =
    _pUserLang->_styleArray.getStyler(STYLE_WORD2_INDEX);
  styleUpdate(w2Style, _pFgColour[1], _pBgColour[1],
    IDC_KEYWORD2_FONT_COMBO, IDC_KEYWORD2_FONTSIZE_COMBO,
    IDC_KEYWORD2_BOLD_CHECK, IDC_KEYWORD2_ITALIC_CHECK,
    IDC_KEYWORD2_UNDERLINE_CHECK);

  Style & w3Style =
    _pUserLang->_styleArray.getStyler(STYLE_WORD3_INDEX);
  styleUpdate(w3Style, _pFgColour[2], _pBgColour[2],
    IDC_KEYWORD3_FONT_COMBO, IDC_KEYWORD3_FONTSIZE_COMBO,
    IDC_KEYWORD3_BOLD_CHECK, IDC_KEYWORD3_BOLD_CHECK,
    IDC_KEYWORD3_UNDERLINE_CHECK);

  Style & w4Style =
    _pUserLang->_styleArray.getStyler(STYLE_WORD4_INDEX);
  styleUpdate(w4Style, _pFgColour[3], _pBgColour[3],
    IDC_KEYWORD4_FONT_COMBO, IDC_KEYWORD4_FONTSIZE_COMBO,
    IDC_KEYWORD4_BOLD_CHECK, IDC_KEYWORD4_ITALIC_CHECK,
    IDC_KEYWORD4_UNDERLINE_CHECK);
  ....
}

This code was most likely being written through the Copy-Paste method. It resulted in using IDC_KEYWORD3_BOLD_CHECK instead of IDC_KEYWORD3_ITALIC_CHECK. The warning looks a bit strange, telling us about the numbers '7', '7', '6', '7'. Unfortunately, a clearer message cannot be generated.

V525 The code containing the collection of similar blocks. Check items '1316', '1319', '1318', '1323', '1323', '1317', '1321' in lines 954, 955, 956, 957, 958, 959, 960. clist_modern modern_clcopts.cpp 954

  EnableWindow(GetDlgItem(hwndDlg,IDC_CYCLE),FALSE);
  EnableWindow(GetDlgItem(hwndDlg,IDC_MULTITRAY),FALSE);

}

The "IDC_ALWAYSPRIMARY" element is disabled twice. Perhaps some other element was intended to be disabled.

V525 The code containing the collection of similar blocks. Check items '0', '1', '2', '3', '4', '1', '6' in lines 680, 682, 684, 689, 691, 693, 695. sql records.cc 680


static int rr_cmp(uchar *a,uchar *b)

  if (a[0] != b[0])
    return (int) a[0] - (int) b[0];

    return (int) a[1] - (int) b[1];

  if (a[6] != b[6])
    return (int) a[6] - (int) b[6];
  return (int) a[7] - (int) b[7];
}

This is what should have been written here: return (int) a[5] - (int) b[5];

This is what should have been written here: if ( pep7 ) { ... if ( use_joint_probs && prob > max7 ) ... }
