Changing textColor of CMFCBUTTON in disabled state

[Sparsh_21j]

I have the following code:

bool var;
m_button.EnableWindow(var);
If(var)
{
m_button.SetFaceColor((RGB(0,255,0),true);
m_button.SetTextColor((RGB(255,255,255)));
}
else
{
m_button.SetFaceColor((RGB(0,0,255),true));
m_button.SetTextColor((RGB(255,0,0)));
}

Issue is button face color changes correctly in both enabled and disabled state but text color does not change in disabled state.
