C++ (Cpp) CListBox::GetSafeHwnd Examples

Example #1

File: GameReviewDialog.cpp Project: azureskydiver/EasyBridge

	CMyCustomDialog::OnInitDialog();

	// init the tags list control

	// and the collapsed width
	CRect btnRect;

	return TRUE;  // return TRUE unless you set the focus to a control
	              // EXCEPTION: OCX Property Pages should return FALSE

Example #2

File: AddDlg.cpp Project: zephyrer/mfc-project

void CAddDlg::OnBnClickedOk()
{
	// 获得主窗口句柄，用来在列表框中增加数据（虽然这样不安全，但个人喜欢）
	CTextCodeConverterDlg* MainDlg = (CTextCodeConverterDlg*)this->GetParent();	
	ASSERT(MainDlg->GetSafeHwnd());

	// 取得主窗口中的列表框句柄
	CListBox* listBox = (CListBox*)MainDlg->GetDlgItem(IDC_LIST1);
	ASSERT(listBox->GetSafeHwnd());

	GetDlgItemText(IDC_EDIT1,m_strEdit);

	// 如果在启动窗口时为修改内容，则删除对应位置数据之后，然后在增加
	if (m_bUpdate == TRUE)
	{
		listBox->DeleteString(listBox->GetCurSel());
		listBox->InsertString(listBox->GetCurSel(),m_strEdit);
	}
	OnOK();
