警告 C6262：函数使用“27688”字节的堆栈：超过 /analyze:stacksize“16384”。考虑将一些数据移动到堆中

Question

我已经阅读了一些关于这个问题的问题和话题。例如：

Warning message regarding stack size

但我真的不知道如何在方法中隔离问题：

void CCreateReportDlg::ReadOptions()
{
    CHeadingsDlg            dlgHeadings(this);
    COptionsDlg             dlgOptions(this);
    CBrothersDlg            dlgBrothers(this, FALSE);
    CAutoAssignSettingsDlg  dlgAssign(this);
    CString                 strSection = theApp.GetActiveScheduleSection(_T("Options"));

    // headings
    m_strReportTitle = dlgHeadings.GetReportTitle();
    dlgHeadings.GetHeadings(m_aryStrHeading);

    m_eReportMode = dlgOptions.GetReportMode();

    // brother data
    dlgBrothers.GetBrotherData(SOUND, m_aryStrSoundWT, m_aryStrSoundSM, TRUE);
    dlgBrothers.GetBrotherData(PLATFORM, m_aryStrPlatformWT, m_aryStrPlatformSM, TRUE);
    dlgBrothers.GetBrotherData(MIKE, m_aryStrMikeWT, m_aryStrMikeSM, TRUE);
    dlgBrothers.GetBrotherData(ATTENDANT, m_aryStrAttendWT, m_aryStrAttendSM, TRUE);
    dlgBrothers.GetBrotherData(SOUND, m_aryStrBroSoundAll, TRUE);
    dlgBrothers.GetBrotherData(PLATFORM, m_aryStrBroPlatformAll, TRUE);
    dlgBrothers.GetBrotherData(MIKE, m_aryStrBroMikeAll, TRUE);
    dlgBrothers.GetBrotherData(ATTENDANT, m_aryStrBroAttendAll, TRUE);

    CCustomAssignManagerDlg::GetCustomAssignData(m_aryPtrAssign, TRUE, ASSIGN_SORT_HEADING);

    if(m_eReportMode != MODE_MEETING)
    {
        // We need to update the arrays to only include the brothers that are available
        // on both days (so the two arrays become identical)
        ModifyBrotherArrays();
    }

    dlgBrothers.GetBrotherData(m_cbBrother);

    // We need an array of unique names
    // (without first to entries in combo)
    // Used during printing and exporting (multi highlight)
    dlgBrothers.GetBrotherData(m_aryStrNames);
    CBrothersDlg::SortArray(m_aryStrNames);

    // options
    m_bExcludePlatformColumn = dlgOptions.ExcludePlatformColumn();
    m_bExcludePlatformMikeColumn = dlgOptions.ExcludePlatformMikeColumn();
    m_bExcludeAttendColumn = dlgOptions.ExcludeAttendantColumn();

    m_iNumMikeUsers = dlgOptions.GetNumMikeUsers();
    m_iNumSoundUsers = dlgOptions.GetNumSoundUsers();
    m_iNumAttendUsers = dlgOptions.GetNumAttendants();

    dlgOptions.GetMeetingDays(m_iDayWT, m_iDaySM, m_iDayWeek);
    m_iDayWT++;
    m_iDaySM++;
    m_iDayWeek++;

    dlgOptions.GetCustomDateOptions(m_bCustomDate, m_strDateFormat);

    m_bAvoidBack2Back = dlgAssign.AvoidBack2Back();
    m_bCheckForConflicts = dlgAssign.CheckForConflicts();
    m_bSelectNames = dlgAssign.SelectNames();

    theApp.ReadDateMapData(m_mapSPtrBroDates);

    m_bShowNotes = (BOOL)theApp.GetNumberSetting(strSection, _T("ShowNotes"), (int)TRUE);
    m_bNoticeBoard = (BOOL)theApp.GetNumberSetting(strSection, _T("NoticeBoard"), (int)FALSE);

    dlgOptions.ReadAssignStatesInfoEx(m_byAryAutoAssignStates);
}

我知道我可以调整编译器并增加堆栈大小来抑制错误。

但是在我的方法中识别路由原因的基本方法是什么？

第一组变量是CStringArray。然后是 CPtrArray 个对象，类型为 CUSTOM_ASSIGN_S:

typedef struct tagCustomAssignment
{
    int     iIndex;
    CString     strDescription;
    CString     strHeading;
    BOOL        bExcluded;
    CStringArray    aryStrBrothersAll;
    CStringArray    aryStrBrothersWT;
    CStringArray    aryStrBrothersSM;

    BOOL        bIncludeWT;
    BOOL        bIncludeTMS;

    BOOL        bFixed;
    int     iFixedType;

} CUSTOM_ASSIGN_S;

同样，上述结构的none个成员是大数组[xxx]。唯一其他值得注意的方法是 ReadDateMapData，它读取存档并填充另一个地图。

但如前所述，我不知道如何隔离问题。没有定义大数组。一两个 TCHAR file[_MAXPATH]; 但仅此而已。类的其余部分，如 CStringArray 或 CPtrArray 等。

提前致谢。

更新

根据提供的评论，我能够确定即使只是顶部的变量声明：

CHeadingsDlg            dlgHeadings(this);
COptionsDlg             dlgOptions(this);
CBrothersDlg            dlgBrothers(this, FALSE);
CAutoAssignSettingsDlg  dlgAssign(this);
CString                 strSection = theApp.GetActiveScheduleSection(_T("Options"));

会导致它的堆栈大小为 18072。

我在这个 class 中的主要变量实际上是 dialog 对象，由于所有成员变量等原因，这些对象非常大，这是可以理解的。

我使用这些对话框的原因是通过使用它们的 public 方法来访问应用程序设置。

通过将这些对话声明更改为 new / delete 并调整代码，我不再收到堆栈大小警告：

void CCreateReportDlg::ReadOptions()
{
    CHeadingsDlg *pDlgHeadings = new CHeadingsDlg(this);
    if (pDlgHeadings != NULL)
    {
        m_strReportTitle = pDlgHeadings->GetReportTitle();
        pDlgHeadings->GetHeadings(m_aryStrHeading);

        delete pDlgHeadings;
    }

    COptionsDlg *pDlgOptions = new COptionsDlg(this);
    if (pDlgOptions != NULL)
    {
        m_eReportMode = pDlgOptions->GetReportMode();
        m_bExcludePlatformColumn = pDlgOptions->ExcludePlatformColumn();
        m_bExcludePlatformMikeColumn = pDlgOptions->ExcludePlatformMikeColumn();
        m_bExcludeAttendColumn = pDlgOptions->ExcludeAttendantColumn();
        m_iNumMikeUsers = pDlgOptions->GetNumMikeUsers();
        m_iNumSoundUsers = pDlgOptions->GetNumSoundUsers();
        m_iNumAttendUsers = pDlgOptions->GetNumAttendants();

        pDlgOptions->ReadAssignStatesInfoEx(m_byAryAutoAssignStates);
        pDlgOptions->GetCustomDateOptions(m_bCustomDate, m_strDateFormat);

        pDlgOptions->GetMeetingDays(m_iDayWT, m_iDaySM, m_iDayWeek);
        m_iDayWT++;
        m_iDaySM++;
        m_iDayWeek++;

        delete pDlgOptions;
    }

    CBrothersDlg *pDlgBrothers = new CBrothersDlg(this, FALSE);
    if (pDlgBrothers != NULL)
    {
        pDlgBrothers->GetBrotherData(SOUND, m_aryStrSoundWT, m_aryStrSoundSM, TRUE);
        pDlgBrothers->GetBrotherData(PLATFORM, m_aryStrPlatformWT, m_aryStrPlatformSM, TRUE);
        pDlgBrothers->GetBrotherData(MIKE, m_aryStrMikeWT, m_aryStrMikeSM, TRUE);
        pDlgBrothers->GetBrotherData(ATTENDANT, m_aryStrAttendWT, m_aryStrAttendSM, TRUE);
        pDlgBrothers->GetBrotherData(SOUND, m_aryStrBroSoundAll, TRUE);
        pDlgBrothers->GetBrotherData(PLATFORM, m_aryStrBroPlatformAll, TRUE);
        pDlgBrothers->GetBrotherData(MIKE, m_aryStrBroMikeAll, TRUE);
        pDlgBrothers->GetBrotherData(ATTENDANT, m_aryStrBroAttendAll, TRUE);
        pDlgBrothers->GetBrotherData(m_cbBrother);

        // We need an array of unique names (without first two entries in combo)
        // Used during printing and exporting (multi highlight)
        pDlgBrothers->GetBrotherData(m_aryStrNames);
        CBrothersDlg::SortArray(m_aryStrNames);

        delete pDlgBrothers;
    }

    CAutoAssignSettingsDlg *pDlgAssign = new CAutoAssignSettingsDlg(this);
    if (pDlgAssign != NULL)
    {
        m_bAvoidBack2Back = pDlgAssign->AvoidBack2Back();
        m_bCheckForConflicts = pDlgAssign->CheckForConflicts();
        m_bSelectNames = pDlgAssign->SelectNames();

        delete pDlgAssign;
    }

    CCustomAssignManagerDlg::GetCustomAssignData(m_aryPtrAssign, TRUE, ASSIGN_SORT_HEADING);

    if(m_eReportMode != MODE_MEETING)
    {
        // We need to update the arrays to only include the brothers that are available
        // on both days (so the two arrays become identical)
        ModifyBrotherArrays();
    }

    theApp.ReadDateMapData(m_mapSPtrBroDates);

    CString strSection = theApp.GetActiveScheduleSection(_T("Options"));

    m_bShowNotes = (BOOL)theApp.GetNumberSetting(strSection, _T("ShowNotes"), (int)TRUE);
    m_bNoticeBoard = (BOOL)theApp.GetNumberSetting(strSection, _T("NoticeBoard"), (int)FALSE);
}
