Hi everybody !!
Just taking a time to visit the comunity and download the new version of PB (Looks great!!).

Im playing with the possibilitie of develop a small IRC client, i done some before in VB.

Now... my questions:

I do connect succesfully

Port = 6663
ConnectionID = OpenNetworkConnection("toast.DAL.net", Port)

Then i need to pass some raw data to the server, in VB it looks like this:

irc.SendData "User " & EMail & " " & irc.LocalHostName & " " & irc.RemoteHost & " :" & RealName & vbCrLf

irc.SendData "NICK " & NickName & vbCrLf

I try to this something similar in PB doing:

If ConnectionID
MessageRequester("PureBasic IRC - Client", "Client connected to server...", 0)
PokeS(TextBuffer, "User [url]mailto:mymail@yahoo.com[/url] 209.13.250.61 ricardo")
Delay (1000)
SendNetworkData(ConnectionID, TextBuffer,1000)
PokeS(TextBuffer, "Nick ricardo")
Delay (1000)
SendNetworkData(ConnectionID, TextBuffer,1000)
EndIf

But something is missing since the server dont let me in and quit me because some timerout of ping.

In VB this easy steps make the server to let me in and then i only need to send some easy raw data and i have a IRC client.

Could some one help me?

My code is a mess but i put it here to see if someone get how to workarround the problem. Thanks in advance.

If InitNetwork() = 0
MessageRequester("Error", "Can't initialize the network !", 0)
End
EndIf

#WINDOW_PARAMETERS = #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget

Port = 6663

TextBuffer = AllocateMemory(1, 1000, 0)

If OpenWindow(0,100,100, 300, 300, #WINDOW_PARAMETERS ,"IRC CLIENT")
If CreateGadgetList(WindowID())

StringGadget(1, 100, 250, 150, 20, "")

EndIf

ConnectionID = OpenNetworkConnection("toast.DAL.net", Port)

If ConnectionID

end
EndIf

If result

EndIf

Hi, why do you have all these delays? Well now to some small things that caught my attention in your code:
* In VB you have the character 'vbCrLf' -this is possibly a neccessary component that is missing in your PB code.
* You should use 'NetworkClientEvent()' in your event loop,and change 'WaitWindowEvent()' to 'WindowEvent()', when doing this you need to put a delay(1) or similar in an appropriate spot in the event loop.

Below I'll suggest some changes that you can make in your code:

Code: Select all

EOL$ = Chr(13)+ Chr(10) ; vbCrLf i.e. End of Line Char
 
sendmsg$ = "User [url]mailto:mymail@yahoo.com[/url] 209.13.250.61 ricardo"+EOL$
sendmsg$ + "Nick ricardo"+EOL$
 
SendNetworkData(ConnectionID, @sendmsg$, Len(sendmsg$))

Start with the changes above and see if it helps a bit...

; Like a Localhost (127.0.0.1) i using a IRC server VB open source that some guy develop

Hi ricardo
Some weeks ago, i started to code just for fun an irc client like mirc too! Its not an official project atm... but will be soon (when other stuff/projects are finished!) i hope

I have to much projects started but now i will stop this and will finish one project after the next

First i will finish a very small (98% finished) project but due fact of a bug or let us say a missed feature in PureBasic (ComboBoxGadget Events) i dont get really manage to get the program work as i want ;(( The app is really nothing special so its more demotivated that it dont work atm and i dont really know how to solve the prob atm ;( We will see...

Hi Ricardo!

Nice work, i took only a small look on your source and I must see that you did the same mistake like we. You code might work but you possible loose datas in the network couse you dont process all of them.

if you do a sendnetworkdata() on the server-side, be sure to check receivenetworkdata() receives the right amount of datas that you have send.

If you use one sendnetworkdata() you possible have to call reveivenetworkdata more then twice times on the other peer side.
receivenetworkdata() is the same as the WinAPI recv_(). Take a look in the WinAPI for correct handling and receiving of datas.

Hi ricardo
I looked in a real hurry to your source and i think you forgot to share your "ConnectionID" to your Timer() procedure...!? If you disable your debugger and dont share the variable, it works fine for me! But if you enable the debugger it will not work! (FRED: Seems there is a debugger bug!?)

Just share your variable and it will work in both modes very fine

Code: Select all

 
    Procedure Timer()
      Shared ConnectionID
      EOL$ = Chr(13)+ Chr(10)
      Delay(500)
      SendNetworkString(ConnectionID," PONG "+EOL$)
      RichEditLocate(0,1000)
    EndProcedure

Hope this help you a bit... good luck and happy coding
