Jkeith247 Posted February 29, 2012 Share Posted February 29, 2012 (edited) I am trying to call a function sent to my program through a UDP string. On the client side, I am trying to send $portsend = UDPOpen("192.168.100.87", 6969) $string = '"RENAMEPC", "VANQUISH"' UDPSend($portsend, $string) On the server side, I am using the while loop to listen for the UDP command with the following loop While 1 $funccal = UDPRecv($port, 100000) If $funccal <> "" Then Call($funccal) ConsoleWrite($funccal & @lf) UDPSend($portsend, "RECEIVED" & $funccal) $funccal = "" EndIf Sleep(10) WEnd For some reason I can not get the function called with the arguments. I do not get it. What can I be doing wrong? Thank you for all of your help! Edited February 29, 2012 by Jkeith247 Link to comment Share on other sites More sharing options...
BrewManNH Posted February 29, 2012 Share Posted February 29, 2012 What does $funccal contain after it receives the data? You're only checking to see if it's empty, you're not checking to see if it contains what you want. Put a consolewrite after the UDPRecv line to see what is inside $funccal. Also, have you checked the return from UDPSend to see if it was successful? If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

Jkeith247 Posted February 29, 2012 Author Share Posted February 29, 2012 What does $funccal contain after it receives the data? You're only checking to see if it's empty, you're not checking to see if it contains what you want. Put a consolewrite after the UDPRecv line to see what is inside $funccal. Also, have you checked the return from UDPSend to see if it was successful?I do have a console write line in to see what it contains. It most definetly contains everything I am sending verbatim... Basically I am not having issue sending or receiving strings... This issue is "How to send this string" so that it calls the function with the variables properly. I can call standard functions any time ex. Function() When I try to call a function ex. Function(variable) is when the problem starts. Thanks again for the help!

BrewManNH Posted February 29, 2012 Share Posted February 29, 2012 Try doing a string split on the received data and use the array to call the function. Maybe something like this would work? While 1 $funccal = UDPRecv($port, 100000) If $funccal <> "" Then $Test = StringSplit($funccal, ",") Call($Test[1], $Test[2]) ConsoleWrite($funccal & @LF) UDPSend($portsend, "RECEIVED" & $funccal) $funccal = "" EndIf Sleep(10) WEnd If I posted any code, assume that code was written using the latest release version unless stated otherwise.

I tried to call it and it reported errors when the second field after the comma was left empty... However the Function that requried variables did work ok... Something strange I hav enoticed though is in my console I am finding digits added to the left of my strings when I console write the $funcal. So MUTE, appeared as 5060MUTE, . I guess I could write a If to check for the variable containing a comma, but this seems inefficient... What do you think? Link to comment Share on other sites More sharing options...
BrewManNH Posted February 29, 2012 Share Posted February 29, 2012 If you're using it sometimes with and without optional parameters, you could do it this way. Local $Parameters, $Test While 1 $funccal = UDPRecv($port, 100000) If $funccal "" Then $Test = StringSplit($funccal, ","); split on the comman $Parameters = "" If $Test[0] > 1 Then For $I = 2 To $Test[0] $Parameters &= $Test[$I] & "," ;adds the comma back in. Next Call($Test[1], $Parameters) Else Call($Test[1]) EndIf ConsoleWrite($funccal & @LF) UDPSend($portsend, "RECEIVED" & $funccal) $funccal = "" EndIf Sleep(10) WEnd If I posted any code, assume that code was written using the latest release version unless stated otherwise.

kylomas Posted February 29, 2012 Share Posted February 29, 2012 jkeith247, The following may be a simpler way to do this: SERVER; server UDPStartup() OnAutoItExitRegister("Cleanup") Local $socket = UDPBind("127.0.0.1", 65532) If @error <> 0 Then Exit While 1 Local $data = UDPRecv($socket, 50) ConsoleWrite($data & @lf) If $data <> "" Then Execute($data) Sleep(100) WEnd Func Cleanup() UDPCloseSocket($socket) UDPShutdown() EndFunc ;==>Cleanup Func renamepc($parm1) MsgBox(0,'',$parm1,1) endfunc CLIENT; client UDPStartup() OnAutoItExitRegister("Cleanup") Local $socket = UDPOpen("127.0.0.1", 65532) If @error <> 0 Then Exit Local $n = 0 While 1 Sleep(2000) $n = $n + 1 Local $status = UDPSend($socket, "renamepc('vanquish')") If $status = 0 Then MsgBox(0, "ERROR", "Error while sending UDP message: " & @error) Exit EndIf WEnd Func Cleanup() UDPCloseSocket($socket) UDPShutdown() EndFunc ;==>Cleanup If this is incredibly naive then mea culpa, first attempt at network code.
