将消息发送到ListBox

Question

我正在尝试将一些字符串添加到列表框中。这是否可以从函数发送消息以将字符串添加到列表框中？

Answer 1

我得到了正确的代码。如下......

LPTSTR  lpBuffer = m_WindowTitle.GetBuffer( );
HWND listHWnd = ::GetDlgItem(AfxGetMainWnd()->m_hWnd, IDC_LIST1);
SendMessage(listHWnd, LB_ADDSTRING, 0, (LPARAM)lpBuffer);
m_WindowTitle.ReleaseBuffer ( );

感谢您的帮助。

Answer 2

您可以为列表框创建成员变量，并说出m_ctrlListBox.AddString或

CListBox *pMyList = (CListBox *) GetDlgItem(IDC_LIST1);
pMyList->AddString("My String");

如果您想发送消息，那么您可以尝试这些

SendMessage(MAKEINTRESOURCE(IDC_LIST1), LB_INSERTSTRING, Index, (LPARAM)lpBuffer);

SendMessage(hWnd, LB_ADDSTRING, NULL, (LPARAM)lpBuffer);

示例：

    CString myString("Hi");
    LPTSTR  lpBuffer = myString.GetBuffer(myString.GetLength());

    CWnd* cw= GetDlgItem(IDC_LIST1);
    ::SendMessage(cw->GetSafeHwnd(), LB_INSERTSTRING, 0, (LPARAM)lpBuffer);
    myString.ReleaseBuffer ( );
