How i can call my OnUpdate function

[NicolasG_99]

I am trying to create a window with certain information, the window has a countdown, and I would like to know how to call the OnUpdate function

void OnUpdate(float fDeltaTime, ULONG ElapsedTime);

I know that the other functions are called from UIBase, but my function just doesn't get called at all, do I have to add the header file path or something like that somewhere?
