Application sent twice the same message

Question

I’m having a new problem with the skype library (skype4com). Actually there are two problems. I’m doing my application in WindowsForm (C#).

I made an app to send automatic reply in skype.

private Skype skypeId;
private string resposta = "**********ESTA E UMA RESPOSTA AUTOMATICA**********";

private void Form1_Load(object sender, EventArgs e)
{            
    //captura a instancia do skype
    skypeId = new Skype();
    skypeId.Attach(7, false);

    //Monitor
    skypeId.MessageStatus += new _ISkypeEvents_MessageStatusEventHandler(skypeId_MessageStatus);

}

public void skypeId_MessageStatus (ChatMessage msg, TChatMessageStatus status)
{
    if(msg.Body != "")
    {
        System.Threading.Thread.Sleep(5000);
        try
        {
            skypeId.SendMessage(msg.Sender.Handle, resposta);
        }
        catch (Exception err)
        { 

        }
    }
}

What happens is that when a message arrives in skype the app sends after 5 seconds twice the message resposta. I tried to put a variable bool to check and was equal below, but did not work:

public void skypeId_MessageStatus (ChatMessage msg, TChatMessageStatus status)
{
    bool novaMsg = true;
    if(msg.Body != "" && novaMsg == true)
    {
        novaMsg = false;
        System.Threading.Thread.Sleep(5000);
        try
        {
            skypeId.SendMessage(msg.Sender.Handle, resposta);
        }
        catch (Exception err)
        { 

        }
    }
}

Another problem is that only this sent the response to new messages from people, group messages is not answered. I’ve seen here in a question from another user that the form of chat response is like this Ex.: msg.Chat.SendMessage("Mensagem");, but how can I differentiate a normal chat from a group chat in skype?

Answer 1

In the method that responds to a new message I used a condition to reply:

public void skypeId_MessageStatus (IChatMessage msg, TChatMessageStatus status)
if(status == TChatMessageStatus.cmsReceived)
{
    skype.SendMessage(msg.FromHandle, resp);                 
}

So when a new message is answered it becomes no longer the type Received TChatMessageStatus.cmsReceived, and when checking the status does not enter the condition of "new message".
