Catch WM_POWERBROADCAST

[rmatthew]

I have read that the system will broadcast power status changes on WM_POWERBROADCAST. Ok - call me stupid but I can't seem to find an example on how to receive/trap these messages. I have not needed to do this kind of thing in the past (so I guess it is something I have missed along the way :) ) Any help would be appreciated.

 

Thanks

I'm not sure if this will work for you, but you can override the WndProc of your form to check for messages. Some won't get sent still as they're being passed on to appropriate controls - but you can try it and see if it works.

 

I'm sorry this is C# - just noticed this is the VB forum. I don't know how to convert override into VB.NET :)

 

protected override void WndProc(ref System.Windows.Forms.Message msg)
{
// Replace WM_LBUTTONDOWN with WM_POWER... (I don't konw its value)
const int WM_LBUTTONDOWN = 0x201;
if(msg.Msg == WM_LBUTTONDOWN)
{
	// Do something
	Debug.WriteLine("hit");
}
base.WndProc(ref msg);
}
