Question

嗨，我有两个问题：

cannot convert from 'std::vector<_Ty>' to 'std::vector<_Ty> &

void CMapObjectPropertyPageAmbience::OnUpdateUI(CProperty* pProperty)
{
    prt::PropertyAmbienceStringToData(pProperty, &m_propertyAmbience);

    std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector;
    for (DWORD dwIndex = 0; dwIndex < rSoundFileNameVector.size(); ++dwIndex)
    {
        m_ctrlSoundFileList.InsertString(dwIndex, rSoundFileNameVector[dwIndex].c_str());
    }

    m_ctrlPlayType.SelectString(-1, m_propertyAmbience.strPlayType.c_str());

    SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL, m_propertyAmbience.fPlayInterval);
    SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL_VARIATION, m_propertyAmbience.fPlayIntervalVariation);
    SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_MAX_VOLUME_AREA_PERCENTAGE, m_propertyAmbience.fMaxVolumeAreaPercentage * 100.0f);

    OnUpdatePropertyData(m_propertyAmbience.strName.c_str());
    OnChangePlayType();
}

错误出现在：

std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector;

2个重载都不能转换所有参数类型：

void CMapObjectPropertyPageAmbience::OnDeleteSoundFile()
{
    DWORD dwCurSel = DWORD(m_ctrlSoundFileList.GetCurSel());
    if (dwCurSel >= m_propertyAmbience.AmbienceSoundVector.size())
        return;

    DeleteVectorItem < CFilename > ( & m_propertyAmbience.AmbienceSoundVector, dwCurSel);
    m_ctrlSoundFileList.DeleteString(dwCurSel);
}

在DeleteVectorItem<CFilename>(&m_propertyAmbience.AmbienceSoundVector, dwCurSel);

Answer 1

您正试图在需要vector<string>的地方使用vector<CFilename>。那些是完全不相关的类型。

无法从'std :: vector＆lt; _Ty＆gt;'转换到'std :: vector＆lt; _Ty＆gt; ＆安培;
