The new TTrayIcon component of C++ Builder 2006 makes it very easy to
create system tray balloons :

TrayIcon1->BalloonTitle="Title";
TrayIcon1->BalloonHint="Body Text";
TrayIcon1->ShowBalloonHint();

This works great. But I also would like to handle the event when a
user clicks the balloon.

The NIN_BALLOONUSERCLICK is sent when the balloon is dismissed because
the user clicked the mouse.

The NIN_BALLOONUSERCLICK was unknown to builder 2006 so I grabbed its
definition from the Windows SDK's ShellAPI.h.

In order to catch the message I wrote this :

class TMainForm : public TForm
{
protected:
	#define NIN_BALLOONUSERCLICK (WM_USER + 5)

	void __fastcall HandleBalloonClick (TMessage &Msg);
	BEGIN_MESSAGE_MAP
		MESSAGE_HANDLER (NIN_BALLOONUSERCLICK,
TMessage,HandleBalloonClick)
	END_MESSAGE_MAP (TForm)
...
}

Finally I added :

void __fastcall TMainForm::HandleBalloonClick (TMessage &Msg)
{
	Caption="Click Balloon";
}

However, when I click the balloon to make it disappear my function
does not get called. 

Any ideas on how to receive the NIN_BALLOONUSERCLICK message ?
