Hi everyone,

I've already searched the forum, but could'nt find any helpful solution for me.  :-\

I'm searching a source code for a C# BNET channel bot. A easy form-based example project, which is using MBNCSUtil or B# would make me really happy.
I've already found this: http://www.jinxbot.net/wiki/index.php?title=How_to_develop_a_Battle.net_client_in_10_minutes
But since it's only command line and an old version, it doesn't help me much. Even I couldn't get a form-based application to work with this tutorial.

So, if someone got a example project or a source code of a working bot for me, you guys would make me the happiest guy in this forum!
Thanks in advance!!!

Best Regards
Dave

No offense Dave but if you couldn't put a battle.net bot together by comparing a console-based bot then its not the battle.net inners that's your problem.. it's the OOP and C# it's self.. you should probably check out some tutorials for GUI based things in C# instead of battle.net

Most likely, what you're running into is problems handling cross-thread events.  As the BN# documentation notes for every event:

QuoteEvents in the JinxBot API are never guaranteed to be executed on the UI thread. Events that affect the user interface should be marshaled back to the UI thread by the event handling code. Generally, high-priority event handlers are raised on the thread that is parsing data from Battle.net, and lower-priority event handler are executed from the thread pool.

I personally handle the fact that BN# is multi-threaded by encapsulating that behavior within the UI elements.  So for instance, in my chat display:

        // Checks to see if Invoke is required to add the chat nodes to the window.
        private void AddChatPrivate(List<ChatNode> nodes)
        {
            for (int i = 0; i < nodes.Count; i++)
            {
                if (nodes[i] == null)
                    throw new ArgumentNullException("nodes");
            }

            if (InvokeRequired)
                BeginInvoke(AddChatImplementation, nodes);
            else
                AddChatImplementation(nodes);
        }


In my channel list:

        private delegate void Invokee<T>(T args);

        void JoinedChannel(object sender, ServerChatEventArgs e)
        {
            if (InvokeRequired)
                Invoke(new Invokee<ServerChatEventArgs>(ClearChannelList), e);
            else
                ClearChannelList(e);
        }

        void UserFlagsUpdated(object sender, UserEventArgs e)
        {
            if (m_voidView && "The Void".Equals(m_client.ChannelName, StringComparison.Ordinal)) /* void view */
            {
                if (InvokeRequired)
                    BeginInvoke(new Invokee<UserEventArgs>(ShowUser), e);
                else
                    ShowUser(e);
            }
        }

        void UserShown(object sender, UserEventArgs e)
        {
            if (InvokeRequired)
                BeginInvoke(new Invokee<UserEventArgs>(ShowUser), e);
            else
                ShowUser(e);
        }

        void UserLeft(object sender, UserEventArgs e)
        {
            if (InvokeRequired)
                BeginInvoke(new Invokee<UserEventArgs>(RemoveUser), e);
            else
                RemoveUser(e);
        }


Using InvokeRequired, BeginInvoke and Invoke are the standard practice for handling cross-thread UI calls in .NET because Windows may only update UI elements from the UI thread.

Hey MyndFyre[vL] ,

you pointed it out, this is exactly my problem using the B# documentation.
Gonna try to implent it the way you've explained it.

Thanks a lot!!!

MyndFyre, Could you explain your above code. I'm having a little bit of trouble understanding it. The current code i use to add to my RichTextBox seems to be fail compared to what you use however i am not sure how yours works unless of course i am misunderstanding what you posted which is also possible.

My Current Code


    public class message
    {
        public System.Drawing.Color c;
        public string txt;
        public message(System.Drawing.Color c, string txt)
        {
                this.c = c;
                this.txt = txt;
        }
    }


        public void rtbADD(System.Windows.Forms.RichTextBox r, params Asgard.Structs.message[] o)
        {
            string result = string.Format("[{0}] ", DateTime.Now.ToLongTimeString());
                if (r.InvokeRequired)
                {
                    Forms.frmBot.EmptyDelegate del1 = delegate()
                    {
                        rtbADD(r, o);
                    };
                    r.Invoke(del1);
                }
                else
                {
                    r.SelectionStart = r.TextLength;
                    r.SelectionLength = 0;
                    r.SelectionColor = Color.White;
                    r.SelectedText = result;
                    for (int i = 0; i != o.Length; i++)
                    {
                        r.SelectionStart = r.TextLength;
                        r.SelectionLength = 0;
                        r.SelectionColor = o[i].c;
                        if (i == (o.Length - 1))
                        {
                            r.SelectedText = o[i].txt + Environment.NewLine;
                        }
                        else
                        {
                            r.SelectedText = o[i].txt;
                        }

                    }
                    if (r.Lines.Length >= 500)
                    {
                        r.SelectionStart = 0;
                        r.SelectionLength = r.Text.IndexOf('\n') + 1;
                        r.SelectedText = " ";
                        r.SelectionStart = 0;
                        r.SelectionLength = r.Text.IndexOf(']');
                        r.SelectedText = r.SelectedText.Substring(1);
                        r.SelectionStart = r.Text.Length;
                        r.ScrollToCaret();
                    }
                    else
                    {
                        r.SelectionStart = r.TextLength;
                        r.ScrollToCaret();
                    }
                }
            }
        }

and on my frmMain form i have
        public delegate void EmptyDelegate();

MyndFyre

You have to understand that my code is more object-oriented than yours, in that my library has a class called "DisplayBox" and another called "ChatBox" (ChatBox wraps DisplayBox), and that each instance of one of these objects contains its own rich text display (I actually use a WebBrowser control).  I don't need to pass in a RichTextBox (or WebBrowser in my case) as a parameter because it is contained by the object on which the AddChat function is being called.

DisplayBox has an overloaded function called AddChat.  These overloads package up their parameters nicely for AddChatPrivate (shown in my previous post).  AddChatPrivate then calls AddChatImplementation, potentially using the Windows Forms invoke/thread-marshaling semantics as necessary.  This is nice because each method in the chain has a single responsibility, though it creates some additional overhead as multiple methods need to be called.

The same general practice is used in my listbox control.  Each event handler checks to see whether invoking needs to happen and calls the domain-specific function appropriately, invoking if necessary.

I really need to spend some time creating an architecture diagram about how JinxBot works, because one of my goals is to use it to teach other people.

Hey guys,

just tried to build it the way MyndFyre explained it. But somehow I'm not able to get it to work.
Never worked with threads this way, only used the background worked and got it always to work somehow.
... and even don't know how "Invoke" works.

Maybe someone of you guys could tell me, what I have to change. Here is the code without "Invoke".
Sorry. I hope I'm not annoying.

Thanks in advance.
Best Regards, Dave

Addchat function...

Public Sub AddChat(Optional ByVal TextColor As Long = vbWhite, Optional ByVal strText As String = "", Optional ByVal ClearTextLenOver As Long = 50000)
    With Form1.rtbChat
        If Len(.Text) > ClearTextLenOver Then .Text = ""
        .SelStart = Len(.Text)
        .SelColor = TextColor
        .SelText = .SelText & strText
        .SelStart = Len(.Text)
    End With
End Sub

But, it can do like this:

text1.text = text1.text + "What ever text you wanna type"

Hey, thanks for your answer!
But before adding some "add chat text" function I need to build up a working connection to BNET, and so far this doesn't work :/

Somehow I managed to get the invoke working.

        delegate void del(string text);
        private void bnet_chat_add(string text)
        {
            if (InvokeRequired)
            {
                del d = new del(bnet_chat_add);
                this.Invoke(d, new object[] { text });
            }
            lstB_bnet_chat.Items.Add(text);
        }


But as soon as I try to connect, the application freezes and I get a error message which says something like:
"No data can be written into the transmission connection: An existing connection was closed by the remote host."

Someone got an idea?

Regards Dave

Michael

This may not be the problem but most of your code doesn't format the string correctly.

                bnet_chat_add("<{0} {1}>" + e.Username + e.Text);

your code will be outputted as "<{0} {1}>UsernameText"
You need to use

string.Format("<{0} {1}>", e.Username , e.Text);

and that will output "<Username Text>"
This may cause your problem however i could be wrong.

MyndFyre

Well your CdKey1 property is returning an empty string, so that's not good.  It could just be an automatic property like you've implemented CdKey2, since you try to set it yourself.

But the specific error message you're getting means you've been banned.
