It may be ..

C#

m_objMediaControl.Pause()

but Im taking a guess, I dont know your m_objMediaCOntrol is derived from

I would think you would code something like

long my_State;
m_objMediaControl.GetState(1000, my_State);
if (my_State == State_Paused)
{
    m_objMediaControl.Run();
}
else 
{
    m_objMediaControl.Pause();
}
