The InvalidatePluginmethod places a request to redraw the plug-in.

Syntax 

HRESULT InvalidatePlugin (
  HPLUGIN 
hPlugin,
  DWORD 
dwFlags 
);

Parameters

hPlugin

[in] Handle to the plug-in to be redrawn.

dwFlags

[in] Indicates whether the height or selectability state of the plug-in has changed. If no flag is passed, the value must be 0; if either the height or the selectability of the plug-in changed, the value is IPF_HEIGHT_CHANGED | IPF_SELECTABILITY_CHANGED. (Both flags must be passed together, but only the flag that changed is read.) These flags are described in the following table.

IPF_SELECTABILITY_CHANGED

Set this flag if the selectability state of the plug-in changed. This flag causes the device to redraw the screen, a process that drains the device battery quickly if repeated often.
