Can't move or resize a button

[abdul]

bool CGButton::Size(int width, int height)
    {
        if (CGButton::Handle == NULL)
        {
            return false;
        }
        else
        {
            SendMessage(CGButton::Handle, WM_SIZE, (WPARAM)SIZE_RESTORED, (LPARAM)MAKELPARAM(45, 45));
            CGButton::width = width;
            CGButton::height = height;
            return true;
        }
} 

Above code doesn't resize the button even when the handle isn't NULL.
