如何使用编辑框创建多行属性?我需要一个属性，将显示文本在多行框。

CMFCPropertyGridProperty* pGroup1 = new CMFCPropertyGridProperty(_T("Appearance"));
pGroup1->AddSubItem(new CMFCPropertyGridProperty(_T("Name"), (_variant_t) _T(""), _T("Specifies the text that will be displayed in the property")));
pGroup1->AddSubItem(new CMFCPropertyGridProperty(_T("Comments"), (_variant_t) _T(""), _T("Specifies the text that will be associated with the property")));
m_wndPropList.AddProperty(pGroup1);

似乎在MFC属性网格中没有实现多行属性。您可以使用按钮创建自定义属性，并在用户单击此按钮时显示带有多行编辑控件的对话框。

你可以像在老式编辑器中那样做(替换"n"，"n"以便用户可以用"n"分隔行):

初始化:

CString s = m_initial_params.m_info;
s.Replace("n","\n");
CMFCPropertyGridProperty* pProp = new 
CMFCPropertyGridProperty(misc_get_str_my(IDS_INFO), 
            (_variant_t) s, misc_get_str_my(IDS_INFO));
pProp->SetData(E_PROPERTY_DATA::OBJ_INFO);
pPropCtrl->AddProperty(pProp);
阅读价值:

int nProperty = pProperty->GetData();
if(E_PROPERTY_DATA::OBJ_INFO == nProperty)
{
    m_initial_params.m_info = pProperty->GetValue().bstrVal;
    m_initial_params.m_info.Replace("\n","n");
}
