解码标志不能正常工作

我已经设计了一些标志：解码标志不能正常工作

enum ImportAssignment 
{ 
    OCLMChairman  = 0x00000001, 
    OCLMOpenPrayer = 0x00000002, 
    OCLMClosePrayer = 0x00000004, 
    OCLMConductorCBS = 0x00000008, 
    OCLMReaderCBS = 0x00000016, 
    PTChairman  = 0x00000032, 
    PTHospitality = 0x00000064, 
    WTConductor  = 0x00000128, 
    WTReader   = 0x00000256 
};

在我的对话我读/写的标志从/到注册表：

void CImportOCLMAssignmentHistoryDlg::ReadSettings() 
{ 
    m_dwImportFlags = theApp.GetNumberSetting(theApp.GetActiveScheduleSection(_T("Options")), _T("ImportFlags"), 0); 
} 


void CImportOCLMAssignmentHistoryDlg::SaveSettings() 
{ 
    theApp.SetNumberSetting(theApp.GetActiveScheduleSection(_T("Options")), _T("ImportFlags"), m_dwImportFlags); 
}

SetNumberSetting基本上是一个包装GetProfileInt等。

然后我有两种方法可以将标志编码和解码为一系列BOOL变量（复选框）：

void CImportOCLMAssignmentHistoryDlg::DecodeImportFlags() 
{ 
    m_bImportOCLMChairman = (m_dwImportFlags & ImportAssignment::OCLMChairman); 
    m_bImportOCLMOpenPrayer = (m_dwImportFlags & ImportAssignment::OCLMOpenPrayer); 
    m_bImportOCLMClosePrayer = (m_dwImportFlags & ImportAssignment::OCLMClosePrayer); 
    m_bImportOCLMConductorCBS = (m_dwImportFlags & ImportAssignment::OCLMConductorCBS); 
    m_bImportOCLMReaderCBS = (m_dwImportFlags & ImportAssignment::OCLMReaderCBS); 
    m_bImportPTChairman = (m_dwImportFlags & ImportAssignment::PTChairman); 
    m_bImportPTHospitality = (m_dwImportFlags & ImportAssignment::PTHospitality); 
    m_bImportWTConductor = (m_dwImportFlags & ImportAssignment::WTConductor); 
    m_bImportWTReader = (m_dwImportFlags & ImportAssignment::WTReader); 
} 


void CImportOCLMAssignmentHistoryDlg::EncodeImportFlags() 
{ 
    m_dwImportFlags = 0; // Reset 
    if (m_bImportOCLMChairman) m_dwImportFlags |= ImportAssignment::OCLMChairman; 
    if (m_bImportOCLMOpenPrayer) m_dwImportFlags |= ImportAssignment::OCLMOpenPrayer; 
    if (m_bImportOCLMClosePrayer) m_dwImportFlags |= ImportAssignment::OCLMClosePrayer; 
    if (m_bImportOCLMConductorCBS) m_dwImportFlags |= ImportAssignment::OCLMConductorCBS; 
    if (m_bImportOCLMReaderCBS) m_dwImportFlags |= ImportAssignment::OCLMReaderCBS; 
    if (m_bImportPTChairman) m_dwImportFlags |= ImportAssignment::PTChairman; 
    if (m_bImportPTHospitality) m_dwImportFlags |= ImportAssignment::PTHospitality; 
    if (m_bImportWTConductor) m_dwImportFlags |= ImportAssignment::WTConductor; 
    if (m_bImportWTReader) m_dwImportFlags |= ImportAssignment::WTReader; 
}

当我第一次运行该应用程序时，复选框未被选中。然后我打勾一对夫妇。我关闭对话框并重新打开它。总是前两个被打勾。

我支持64x和32x构建。

我在做什么错？

你'ImportAssignment'标志是错误的，从第一个两位数的值。这些应该是'0x10'，'0x20'，'0x40'，'0x80'，'0x100'。我总是在* Programmer *模式中抽出Windows'* calc.exe *来仔细检查。每个值都应该设置一个位，并清除所有其他位（例如，'0x16'[即十进制22]为二进制的“10110”）。 – IInspectable

@IInspectable感谢您的澄清。我更新了我现在如何定义标志的答案。 –

在进一步的调试中，我找到了解决我的问题的方法。

我不得不调整我的DecodeImportFlags方法：

void CImportOCLMAssignmentHistoryDlg::DecodeImportFlags() 
{ 
    m_bImportOCLMChairman = (m_iImportFlags & ImportAssignment::OCLMChairman) ? TRUE : FALSE; 
    m_bImportOCLMOpenPrayer = (m_iImportFlags & ImportAssignment::OCLMOpenPrayer) ? TRUE : FALSE; 
    m_bImportOCLMClosePrayer = (m_iImportFlags & ImportAssignment::OCLMClosePrayer) ? TRUE : FALSE; 
    m_bImportOCLMConductorCBS = (m_iImportFlags & ImportAssignment::OCLMConductorCBS) ? TRUE : FALSE; 
    m_bImportOCLMReaderCBS = (m_iImportFlags & ImportAssignment::OCLMReaderCBS) ? TRUE : FALSE; 
    m_bImportPTChairman = (m_iImportFlags & ImportAssignment::PTChairman) ? TRUE : FALSE; 
    m_bImportPTHospitality = (m_iImportFlags & ImportAssignment::PTHospitality) ? TRUE : FALSE; 
    m_bImportWTConductor = (m_iImportFlags & ImportAssignment::WTConductor) ? TRUE : FALSE; 
    m_bImportWTReader = (m_iImportFlags & ImportAssignment::WTReader) ? TRUE : FALSE; 
}

它m_iImportFlags & ImportAssignment::XXXXX返回实际的标志值。所以我需要进行条件测试，以便BOOL可以正确设置。

更新：这是我的方法现在宣布国旗：

enum ImportAssignment 
{ 
    /* 
    OCLMChairman  = 1, 
    OCLMOpenPrayer = 2, 
    OCLMClosePrayer = 4, 
    OCLMConductorCBS = 8, 
    OCLMReaderCBS = 16, 
    PTChairman  = 32, 
    PTHospitality = 64, 
    WTConductor  = 128, 
    WTReader   = 256*/ 
    None    = 0, 
    OCLMChairman  = 1 << 0, 
    OCLMOpenPrayer = 1 << 1, 
    OCLMClosePrayer = 1 << 2, 
    OCLMConductorCBS = 1 << 3, 
    OCLMReaderCBS = 1 << 4, 
    PTChairman  = 1 << 5, 
    PTHospitality = 1 << 6, 
    WTConductor  = 1 << 7, 
    WTReader   = 1 << 8 
};
