控件之间发送MW_NOTIFY,没有反应

[wjxfhxy]

我想在Button2中给Button1发送BN_CLICKED消息,但却没有反应,我的代码如下:
void CGfhDlg::OnButton2()
{
NMHDR hdr;
hdr.hwndFrom = ((CButton*)GetDlgItem(IDC_BUTTON1))->m_hWnd;
hdr.idFrom = IDC_BUTTON1;
hdr.code = BN_CLICKED;
SendMessage(WM_NOTIFY, (WPARAM)IDC_BUTTON1, (LPARAM)&hdr);
}

void CGfhDlg::OnButton1()
{
AfxMessageBox(_T(""));
}
不知道何解?

帮你顶下，希望好心人能回答

SendMessage(WM_COMMAND, (WPARAM)IDC_BUTTON1, (LPARAM)0);

多谢楼上的,但为什么是发送WM_COMMAND,而不是WM_NOTIFY呢?

[forimprove]

The WM_NOTIFY message is sent by a common control to its parent window when an event has occurred or the control requires some information.

个人感觉 这样容易：
void CGfhDlg::OnButton2()
{
OnButton1（）；
}

void CGfhDlg::OnButton1()
{
AfxMessageBox(_T(""));
}
