A little help // C#

Question

hello can someone help me to implement these commands in C#? or other but in the same context static string fact = ; fact = find_str_from_to2(responseFromServer > -1 if (fact = 1) then (comp = 11955|708); else if (fact = 2) then (comp = 9080|55); else if (fact = 3) then (comp = 1085|708); // update.. fact must me string because i'm getting he's value from a website.... and i need to use other string.. but i need these if conditions.. ty.

Try: string send = (T|13|3750 + CrLf + \0);

andrei hooba · Answer

ty for help. but i got another issue :/ i have to send a packet to server. the packet look like this: T|13|3750 . hex -> 54 7C 31 33 7C 33 37 35-30 0A 00 i defined a call: string CrLf = (
); string send = (T|13|3750 + CrLf + .); byte[] sendit = System.Text.Encoding.UTF8.GetBytes(send); stream.Write(sendit 0 sendit.Length); in ASCII code the packet looks like T|13|3750 . but in hex it looks like: 54 7C 31 33 7C 33 37 35-30 0A 2E how can i send the required call  but with 00 instead of 2E ?

I hadn't noticed that 'resources' was a string already. Change it to this and it should work: string[] words = resources.Split('|');

andrei hooba · Answer

there are 2 erros on this call: string[] words = resources. Text .Split( '|' ); 1: 'string' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?) 2: Cannot implicitly convert type 'char' to 'string'

Vulpes · Answer

The overload of the String.Split method which you're using takes a single char argument rather than a string. So the call should be: string[] words = resources.Text.Split('|'); // single quotes around the |

andrei hooba · Answer

no i don't. anyway i fixed this issue. but i got another :D i've got this string string resources = find_str_from_to2(responseData 0|E| 0|m|); the response will be like this: 1|2|3|4|5|6|7|8|9 how can i split these values and put those values in another strings? to be like: string a = 1; .. string i = 9; //////// i thought at something like the following method would work.. but... string[] words = resources.Text.Split(|); string a = words[0]; string b = words[1]; string c = words[2]; string d = words[3]; string e = words[4]; string f = words[5]; string g = words[6]; string h = words[7]; string i = words[8];

Do you have control of the server here? If you do I'd use BinaryWriter.Write to write the string to the NetworkStream and then call its Flush method to make sure nothing is left in the buffer.

andrei hooba · Answer

ok. now it catch only : 0|TX|S|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0. 0|A|SET|

Vulpes · Answer

Using BinaryReader to read from the NetworkStream may help if the response string is prefixed with its length. I'd try replacing this part of the code: byData = new Byte[6144]; String responseData = String.Empty; Int32 bytes = stream.Read(byData 0 byData.Length); responseData = System.Text.Encoding.ASCII.GetString(byData 0 bytes); Console.WriteLine(Received: {0} responseData); with this: String responseData = String.Empty; BinaryReader br = new BinaryReader(stream System.Text.Encoding.ASCII); responseData = br.ReadString(); Console.WriteLine(Received: {0} responseData);

the login packet which i send should look like this: LOGIN|uid|clientversion .PNG . and i want to use this method: string CrLf = (
); try { string szData = (LOGIN| + uID + | + ClientVersion + CrLf + .PNG + CrLf +. ); byte[] byData = System.Text.Encoding.UTF8.GetBytes(szData); Int32 port = 8080; TcpClient client = new TcpClient(sGameServerIp port); NetworkStream stream = client.GetStream(); stream.Write(byData 0 byData.Length); byData = new Byte[6144]; String responseData = String.Empty; Int32 bytes = stream.Read(byData 0 byData.Length); responseData = System.Text.Encoding.ASCII.GetString(byData 0 bytes); Console.WriteLine(Received: {0} responseData); } catch (SocketException e) { } the problem is responseData  because it doesn't catch the entire packet received.. it catch only the first line... if response is this: 0|TX|S|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0. 0|A|SET|1|1|1|1|1|1|1|1|1|1|1|0|0|1|1|2|3|1|1|0|0|1|0|1|1. 0|7|QUALITY_POIZONE|3. the responseData gets only the 0|TX|S|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0. how can i get the entire packet/s?

//wrong method used.

Vulpes · Answer

OK so find_str_from_to2 is returning -1 either because it can't find 0|m|5| or it can find it but can't find a subsequent .. As far as I can tell the code should work if responseFromServer does contain what you expect it to. So I'd do a Console.WriteLine(responseFromServer) to make sure that this is in fact the case.

andrei hooba · Answer

here is responseFromServer variable defined static void getResponse(ref WebRequest reqPOST ref WebResponse result ref StreamReader reader ref string responseFromServer) { result = reqPOST.GetResponse(); if (result.Headers.Get(Content-Encoding) != null && result.Headers.Get(Content-Encoding).ToLower() == gzip) reader = new System.IO.StreamReader(new GZipStream(result.GetResponseStream() CompressionMode.Decompress)); else reader = new System.IO.StreamReader(result.GetResponseStream()); responseFromServer = reader.ReadToEnd(); } and here is find_str_from_to2 defined. static string find_str_from_to2(string sMain string sFrom string sTo) { int iBegSubstr = sMain.IndexOf(sFrom); if (iBegSubstr == -1) return -1; iBegSubstr += sFrom.Length; int iEndSubstr = sMain.IndexOf(sTo iBegSubstr); if (iEndSubstr == -1) return -1; return sMain.Substring(iBegSubstr iEndSubstr - iBegSubstr); } //// ok let me explain what the program should do. access let say the page www.test.com -> login on this page -> get some datas from this page and after that send a login packet via send.Socket to some IP:8080 (which is taken from www.test.com page).. ok the account it succesfully conected on that IP:8080  but i dont know how get some datas from response... maybe it's needed to create another 'responsefromserver' for the new ip ?

Vulpes · Answer

I imagine that the find_str_from_to2 method looks in the responseFromServer string for text between 0|m|5| and '.'. So does the responseFromServer variable contain a normal textual string? What happens if you execute this line: Console.WriteLine(responseFromServer);

andrei hooba · Answer

ty for your help. one more thing.. i send this packet IPAddress host = IPAddress.Parse(sGameServerIp); IPEndPoint hostep = new IPEndPoint(host 8080); Socket sock = new Socket(AddressFamily.InterNetwork SocketType.Stream ProtocolType.Tcp); try { sock.Connect(hostep); } catch (SocketException e) { sock.Close(); return; } try { sock.Send(Encoding.UTF8.GetBytes(LOGIN| + ID + ClientVersion)); } catch (SocketException e) { sock.Close(); return; } sock.Close(); and i receive this packet: 0|3|95|150|502|0|0|0|500|0|3|0|0|0|0|0|0. 0|TX|S|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0. 0|A|ITM|0|0|0|0|9|0|0|0|0|0|0|0|0|0|0|0. 0|E|0|0|0|50|0|0|0|0|0. 0|m|5|21000|13500. and i don't know how to get some data's from these packets for ex.: coord = find_str_from_to2(responseFromServer 0|m|5| .); and when i -> Console.WriteLine(coord); the console it write '-1' ... and not 21000|13500 ty

Vulpes · Answer

OK that will then be: if (fact == 1) comp = 11955|708; else if (fact == 2) comp = 9080|55; else if (fact == 3) comp = 1085|708;

andrei hooba · Answer

thank you for your answer but i wroted wrong the 'code' needed.... for each fact must be different comp ..

Vulpes · Answer

Assuming that 'comp' is also a string variable the last bit should be: if (fact == 1 || fact == 3) comp = 11955|708; else if (fact == 2) comp = 9080|55;
