combobox动态创建问题

[cqhcls]

动态创建的COMBOBOX.. 要在改变它的值的时候,调用一个自己写的函数,应该怎么办..


最好有代码给我看,不要说理论... - -!

我是菜鸟...

这样创建的

	
int Count=0;
int left=0;
for(int i=0;i<3;i++)
{
PCombo[i]=new CComboBox;
		PCombo[i]->Create(WS_CHILD|WS_CLIPCHILDREN|WS_VISIBLE|WS_VSCROLL|CBS_DROPDOWNLIST,
			CRect(left+=150,0,100,100),this,Count);

}

谢谢各位

CBN_SELCHANGE Notification

--------------------------------------------------------------------------------

The CBN_SELCHANGE notification message is sent when the user changes the current selection in the list box of a combo box. The user can change the selection by clicking in the list box or by using the arrow keys. The parent window of the combo box receives this notification in the form of a WM_COMMAND message with CBN_SELCHANGE in the high-order word of the wParam parameter.

添加

CBN_EDITCHANGE

消息处理。

你说的改变它的值是什么意思，是组合框中内容改变的吗，是的话如下
当然你可以直接添加CBN_SELECANCEL
手动添加如下：
.h中添加
//{{AFX_MSG(*******)
......................
......................
ON_CBN_SELCHANGE(IDC_COMBO, OnSelchangeCombo)
//}}AFX_MSG
DECLARE_MESSAGE_MAP()

.cpp中添加
BEGIN_MESSAGE_MAP(CYourDlg, CDialog)
//{{AFX_MSG_MAP(CMSGCOMDlg)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
ON_BN_CLICKED(IDC_SEND, OnSend)
ON_WM_CLOSE()
........

ON_CBN_SELCHANGE(IDC_COMBO, OnSelchangeCombo)//添加此代码

//}}AFX_MSG_MAP
END_MESSAGE_MAP()

//在此函数实现你的功能
void CYourDlg::OnSelchangeCombo()
{

}

#define MAX_COUNT 3

#define IDC_COMBOBOX 1112

CComboBox m_combo[MAX_COUNT];

afx_msg void OnSelchangeCombo(UINT nID);

BEGIN_MESSAGE_MAP(CXXXDlg, CDialog)
	
	ON_CONTROL_RANGE(CBN_SELCHANGE, IDC_COMBOBOX, IDC_COMBOBOX+MAX_COUNT, OnSelchangeCombo)
END_MESSAGE_MAP()

// 初始化函数OnInitDialog函数中创建combobox控件
for(int i=0; i<MAX_COUNT; i++)
	{
		m_combo[i].Create(WS_CHILD|WS_VISIBLE|CBS_DROPDOWNLIST, CRect(0, i*30, 100, 100 + i*30),this, IDC_COMBOBOX + i);
		m_combo[i].AddString(_T("AAAAAA"));
		m_combo[i].AddString(_T("BBBBBB"));
                m_combo[i].AddString(_T("CCCCCC"));
		m_combo[i].SetCurSel(0);
	}

// 响应CBN_SELCHANGE
void CXXXDlg::OnSelchangeCombo(UINT nID) 
{
	// TODO: Add your control notification handler code here
	int nIndex = nID - IDC_COMBOBOX;
	CString strText(_T(""));
	m_combo[nIndex].GetLBText(m_combo[nIndex].GetCurSel(), strText);
	AfxMessageBox(strText);
}
