Step 8. Apply Property Changes
Override the CBasePropertyPage::OnApplyChanges method to commit any property changes. In this example, the m_lNewVal variable is updated whenever the user scrolls the slider bar. The OnApplyChanges method copies this value into the m_lVal variable, overwriting the original value:
HRESULT CGrayProp::OnApplyChanges(void)
{
m_lVal = m_lNewVal;
return S_OK;
}
Next: Step 9. Disconnect the Property Page.
