This control contains two buttons. It’s very easy to use. Place a button
control in your CDialog, add a CHiButton member variable (eg
m_wndHiButton), and then in OnInitDialog subclass the control with
m_wndHiButton.SubclassDlgItem(IDC_BUTTON1, this). To handle the
message, it sufficient to add, using the class wizard, a handler for “on button
click”. User can disinguish between which button was pressed using something like:
void CTestDlg::OnHibutton()
{
if (m_hiButton.m_bInsideButton)
AfxMessageBox(_T(“TestInside”));
else
AfxMessageBox(_T(“Test”));
}
The user can attach icon, bitmap, text, or cursor to this control.
