在MFC中获取组合框的价值 [英] Get value of combobox in mfc

问题描述

我是C ++(MFC)编程的初学者. 因此，我有两个组合框:IDC_COMBO1和IDC_COMBO2.

I'm a beginner in C++ (MFC) programming. So, I have two comboboxes: IDC_COMBO1 and IDC_COMBO2 .

我如何才能简单地从他们那里获得按用户选择的值?

How can I simply get the selected by user value from them?

我已经阅读了MSDN，但是我不理解这些示例:

I've read the MSDN, but I didin't understand the examples:

int nIndex = m_pComboBox->GetCurSel();
int nCount = m_pComboBox->GetCount();

我怎么必须声明m_pComboBox?

感谢您的回答.

推荐答案

CString sData;
int nSel = m_NameListBox.GetCurSel();
if (nSel != LB_ERR)
{
   m_NameListBox.GetText(nSel, sData);
}

还请使用DataExchange MFC机制将您的控件映射到类变量:

Please also use DataExchange MFC mechanism to map your control to a class variable:

void CUserSettingsDlg::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    DDX_Control(pDX, IDC_NAME_LISTBOX, m_NameListBox);
}
