messages for trayicon

[CornedBee]

For the user-defined message simply do
#define WM_MYMESSAGE WM_USER + [offset]
replace [offset] by any number > 0 you want.

For MFC:
Add the ON_MESSAGE macro to the message map like this:

// example for ON_MESSAGE
#define WM_MYMESSAGE (WM_USER + 1)
BEGIN_MESSAGE_MAP( CMyWnd, CMyParentWndClass )
    //{{AFX_MSG_MAP( CMyWnd
    ON_MESSAGE( WM_MYMESSAGE, OnMyMessage )
    // ... Possibly more entries to handle additional messages
    //}}AFX_MSG_MAP
END_MESSAGE_MAP( )

OnMyMessage is the message handler function. It must have this prototype:
afx_msg LRESULT OnMyMessage(WPARAM, LPARAM);

how can I put the value of WPARAM of LPARAM in a textbox?

What do those values represent?

[VIsualPenguin]

you said they had to be there, so I've put them there. There has to be a variable that contains the number so I know if someone clicked the icon. In VB these variables are long.

Yes, I know. The first one is a 32-bit unsigned integer and the second one a 32-bit signed integer. But I can't find what they represent. (One must be some flag what happened: mouse click, move, up, down etc)

I know what the lParam can represent. Here is some sample code from my Systray code. It is not MFC though.

case WM_TRAYNOTIFY:                                    //Used For The Systray Msgs
        {
            switch(LOWORD(lParam))    
            {
                case WM_LBUTTONDBLCLK:                        //If Double Click On The Icon
                {
                    BOOL ret;

                    ret = IsWindowVisible(m_hWnd);            //Is Window Already Visable

                    if(ret)
                    {
                        if(m_hWnd_Options != 0x00000000)    //If It Is Set Focus To It
                            SetFocus(m_hWnd);
                    }
                    else
                    {
                        ShowWindow(m_hWnd,SW_SHOW);            //Else Show The Main Window
                        ShowWindow(m_hWnd_Msg,SW_SHOW);        //So The Message List Window
                    }

                    break;
                }  //WM_LBUTTONDBLCLK

                case WM_RBUTTONUP:                            //If A Right Click On The Systray Icon
                {
                    m_SysTray.ShowMenu();                    //Show The Systray Menu
                    break;
                }  //WM_RBUTTONUP

                default:
                    break;
            }
            break;
        }    //WM_TRAYNOTIFY

That would work for MFC too, except for the action taken.

// in message map
ON_MESSAGE(WM_TRAYNOTIFY, OnTrayNotify)

// function
LRESULT CMyWnd::OnTrayNotify(WPARAM wParam, LPARAM lParam)
{
  switch(LOWORD(lParam))
  {
  case WM_LBUTTONDBLCLK:
    if(IsWindowVisible())
    {
      SetFocus();
    }
    else
    {
      ShowWindow(SW_SHOW);
      m_wndMsg.ShowWindow(SW_SHOW);
    }
// ...
  }
}
