Im having a problem using RecieveNetworkData on the serverside [so far] I send a string from the client via SendNetworkString and when i try to retrieve it using ReceiveNetworkData on the serverside it comes out all garbled except the last character. [basically it looks like null spaces to me or invalid chars cause its just a box lol] Im still new to pb too so this is a bit frustrating. I'm using pb4. [BTW the network client/server example in the pb4 help doc don't work either, i get the same effect]

Can anyone help me? I'm really confused.

are you using unicode strings to be send over the network?

That is what I thought too!

Post some code for a test. Use the {code} {/code} commands (use [ for { and ] for } ) or click the Code button near the top white line and click it again when you have pasted your code.

We can see whats going on!

i found a way around that issue using a combination of peeks and pokes but now i have run into another problem.

my server code seems to work fine. now its this thats being a pain, it connects, sends the string but its not recieving the string thats sent back and ive checked the connectionid's over and over in both the server and client. im completely lost. --note; the code will be adapted for a dll so u might see some commented out procedurereturns.

Code: Select all

If InitNetwork() = 0
  ;ProcedureReturn "Unable to initialize the network."
EndIf

Procedure.s ReceiveNetworkString(ConnectionID.l) 
  Length.l = ReceiveNetworkData(ConnectionID, *Buffered, 1000) 
  Text$ = PeekS(*Buffered, Length)
  ProcedureReturn Text$ 
EndProcedure

*Buffered = AllocateMemory(1000)
ConnectionID = OpenNetworkConnection("127.0.0.1", 6832)
If ConnectionID
  stext.s = "regkey"
  PokeS(*Buffered,stext,1000)
  SendNetworkData(ConnectionID, *Buffered, 1000)
  Repeat
    CEvent = NetworkClientEvent(ConnectionID)
    If CEvent
      ;do something
      Select CEvent
        Case 1
          MessageRequester("PureBasic - Server", "Server "+Str(ConnectionID)+" has send a packet !", 0)
          MessageRequester("Info", ReceiveNetworkString(ConnectionID), 0)
          If Text$ = "Invalid registration key"
            CloseNetworkConnection(ConnectionID)
            End
          EndIf
      EndSelect
    EndIf
  Until Quit = 1
EndIf
End

You have to clear the buffer and PARSE the buffer to sort the strings. Well you will eventually... you'll see.

Are you sending to the correct port?

Shouldn't "Case 1" be "Case 2"?
