Windows Messenger COM Questions

[Agonostis]

I am making my first foray into LuaCom, and I have some questions. I appreciate any help.

I'm trying to get information out of Windows (MSN) Messenger. I have this code so far:

LoadLuaCom()
oMessenger = luacom.CreateObject("Messenger.MessengerApp")
oMessenger = nil
collectgarbage()
UnloadLuaCom()

But I'd like to put some stuff that actually does something in it. I'm having trouble distilling the information here into usable LuaCOM information. Can someone please help me?

Here is something very simple - the MSDN stuff is hard to go through. I would google instead..

objMsgr = luacom.CreateObject("Messenger.MsgrObject")
objMsgrApp = luacom.CreateObject("Messenger.MessengerApp")

print ("Messenger state ",objMsgr.LocalState)

--objMsgrApp:LaunchLogonUI ()

objMsgrApp.Visible = 1

Thank Mike, this got me very far.

Now I have a new question, that I think goes like this: can I/how can I make Girder listen for the "ontextrecieved" event with luacom. I tried reading the stuff in the LUA sticky about events, but I got lost and wasn't even sure I was in the right place.

Thanks a bunch!

Can you post some code (ie VB or script) showing how others programs receive events from messanger and I will convert it to luacom for you.

I found a useful website, though i'm still working on deciphering it. One thing I'm having trouble with is methods with no parameters (like the IMSessions method). I always get errors with them, but I think it must be a syntax issue.

Here is some code that I found with events:

using Interop.Messenger;

private void Form1_Load(object sender, System.EventArgs e)
{
    //This next line creates our Messenger Class
    MsgrObjectClass Msgr = new MsgrObjectClass();

    //These 3 lines create the events to be used
    Msgr.OnTextReceived += new DMsgrObjectEvents_OnTextReceivedEventHandler
        (this.OnTextReceived);

    Msgr.OnUnreadEmailChanged += new
        DMsgrObjectEvents_OnUnreadEmailChangedEventHandler
        (this.OnUnreadEmailChanged);

    Msgr.OnUserStateChanged += new
        DMsgrObjectEvents_OnUserStateChangedEventHandler
        (this.OnUserStateChanged);
}

//The TextReceived Event
private void OnTextReceived(IMsgrIMSession Session, IMsgrUser User, 
    string Header, string MsgText, ref bool Enabled)
{
    //Simply write this info to the textbox
    textBox1.Text += User.ToString() + " " + Header.ToString();
    textBox1.Text += " " + Text.ToString();
}

//The OnUnreadEmailChanged event 
private void OnUnreadEmailChanged(Interop.Messenger.MFOLDER Folder, 
    int UnReadEmails, ref bool Enabled)
{
    //Simply write this info to the textbox
    textBox1.Text += "MFOLDER " + Folder.ToString();
    textBox1.Text += "a " + UnReadEmails.ToString();
}

//The OnUserStateChanged event
private void OnUserStateChanged(Interop.Messenger.IMsgrUser User, 
    Interop.Messenger.MSTATE PreviousState, ref bool Enabled)
{
    //Again simply write this info to the textbox
    textBox1.Text += User.FriendlyName + "'s state has changed to " 
        + User.State;

    textBox1.Text += User.FriendlyName + "'s previous state was " 
        + PreviousState;
}

Try...

MsgrObjectEvents = {}

function MsgrObjectEvents:OnTextReceived ()
  print ("text received")
end

if not luacom.Connect (MsgrObject,MsgrObjectEvents) then 
  print ("Unable to connect")
end

Mike,

You are a true fount of knowledge. The code works, but I just get "script finished" at the end.

I think this is a more general Lua/LuaCom question, but how do I make it run until such an event is triggered, and can I do so without chewing up CPU?

Thanks!

[Promixis]

Actually, it does not need to run..

It is always waiting for an event. So, now you need to trigger the event and make sure you see the print statement execute.
