  • [C#] RSACryptoServiceProvider Using the Public Key to decrypt Private Key encrypted Data ?

    - by prixone
    Hello, i went thru lots and lots of searchs and results and pages considering this matter but havent found the solution yet. Like i described in the title i want to decrypt data using my Public Key which is something i am able to do with my PHP code, my certificate is generated from my PHP page. Here is a sample of what i am trying: public string Decrypt(string data) { X509Certificate2 cert = new X509Certificate2(); cert.Import(Encoding.ASCII.GetBytes(webApi["PublicDefaultKey"])); RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)cert.PublicKey.Key; byte[] ciphertextBytes = Convert.FromBase64String(data); byte[] plaintextBytes = rsa.Decrypt(ciphertextBytes, false); return System.Text.Encoding.UTF8.GetString(plaintextBytes); } MessageBox.Show(Decrypt("pgcl93TpVfyHubuRlL72/PZN0nA4Q+HHx8Y15qGvUyTNpI6y7J13YG07ZVEyB7Dbgx63FSw9vEw1D1Z3bvNbI0gqalVfKTfHv5tKVc7Y6nQwQYwoODpUhVpa/K9OP1lqx4esnxqwJx95G0rqgJTdS+Yo773s5UcJrHzzbsX2z+w=")); here is the public key i am using for tests: -----BEGIN CERTIFICATE----- MIIDxDCCAy2gAwIBAgIBADANBgkqhkiG9w0BAQUFADCBozELMAkGA1UEBhMCVUsx EDAOBgNVBAgTB0VuZ2xhbmQxDzANBgNVBAcTBkxvbmRvbjESMBAGA1UEChMJTU1P Q2xldmVyMSMwIQYDVQQLExpNTU9DbGV2ZXIgRGV2ZWxvcGVyJ3MgVGVhbTESMBAG A1UEAxMJTU1PQ2xldmVyMSQwIgYJKoZIhvcNAQkBFhVzdXBwb3J0QG1tb2NsZXZl ci5jb20wHhcNMTAwNTE2MTkxNDQ4WhcNMTEwNTE2MTkxNDQ4WjCBozELMAkGA1UE BhMCVUsxEDAOBgNVBAgTB0VuZ2xhbmQxDzANBgNVBAcTBkxvbmRvbjESMBAGA1UE ChMJTU1PQ2xldmVyMSMwIQYDVQQLExpNTU9DbGV2ZXIgRGV2ZWxvcGVyJ3MgVGVh bTESMBAGA1UEAxMJTU1PQ2xldmVyMSQwIgYJKoZIhvcNAQkBFhVzdXBwb3J0QG1t b2NsZXZlci5jb20wgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAMozHr17PL+N seZyadobUmpIV+RKqmRUGX0USIdj0i0yvwvltu3AIKAyRhGz16053jZV2WeglCEj qfiewF9sYTAAoIVGtdd/sZvO4uUcng9crSzDo0CrEPs/Tn5SunmlmyFlZfdlqpAM XXLno/HMo9cza0CrcMnRokaTiu8szBeBAgMBAAGjggEEMIIBADAdBgNVHQ4EFgQU zip+3/hBIpjvdcSoWQ2rW+xDEWAwgdAGA1UdIwSByDCBxYAUzip+3/hBIpjvdcSo WQ2rW+xDEWChgamkgaYwgaMxCzAJBgNVBAYTAlVLMRAwDgYDVQQIEwdFbmdsYW5k MQ8wDQYDVQQHEwZMb25kb24xEjAQBgNVBAoTCU1NT0NsZXZlcjEjMCEGA1UECxMa TU1PQ2xldmVyIERldmVsb3BlcidzIFRlYW0xEjAQBgNVBAMTCU1NT0NsZXZlcjEk MCIGCSqGSIb3DQEJARYVc3VwcG9ydEBtbW9jbGV2ZXIuY29tggEAMAwGA1UdEwQF MAMBAf8wDQYJKoZIhvcNAQEFBQADgYEAyU6RLifBXSyQUkBFnTcI6h5ryujh+6o6 eQ1wuPOPmRdYJZuWx/5mjMpIF13sYlNorcOv5WaEnp8/Jfuwc9h/jXlcujser0UE WoaaFwK81O801Xkv2zEm2UUWiOabrGTIT4FVy3gCUXJYjaCnvfSdmkfLJOQxNHVt 4NTMp7IeF60= -----END CERTIFICATE----- by default, the PHP generates the key in PKCS as far as i know, from my C# code i can encrypt using my publick key with out any problems and decrypt it on my php page but so far i was not able to decrypt data sent from my php page encrypted with the private key which is something i can do on my php... i did like some help to understand what i am doing wrong... the error when i run the functions is "bad data" at rsa.Decrypt(ciphertextBytes, false); which i couldnt found anymore information at it...

  • Datapager in silverlight 4 -Nested datagrid visibility issue

    - by Archie
    I have a datagrid in silverlight with child datagrid nested in it. Also I have a DataPager on the outer datagrid. The code looks like this: <data:DataGrid x:Name="dgData" Width="600" ItemsSource="{Binding}" AutoGenerateColumns="False" IsReadOnly="True" HorizontalScrollBarVisibility="Hidden" CanUserSortColumns="False" RowDetailsVisibilityChanged="dgData_RowDetailsVisibilityChanged" Margin="20,0" Grid.RowSpan="2"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Item" Width="*" Binding="{Binding ItemName,Mode=TwoWay}"/> <data:DataGridTextColumn Header="Company" Width="*" Binding="{Binding Company,Mode=TwoWay}"/> </data:DataGrid.Columns> <data:DataGrid.RowDetailsTemplate> <DataTemplate> <data:DataGrid x:Name="dgRowDetail" Width="400" HorizontalScrollBarVisibility="Hidden" AutoGenerateColumns="False" Visibility="Collapsed"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Date" Width="*" Binding="{Binding Date,Mode=TwoWay}"/> <data:DataGridTextColumn Header="Price" Width="*" Binding="{Binding Price,Mode=TwoWay}"/> </data:DataGrid.Columns> </data:DataGrid> </DataTemplate> </data:DataGrid.RowDetailsTemplate> </data:DataGrid> <data:DataPager x:Name="dpData" HorizontalAlignment="Center" DisplayMode="FirstLastPreviousNextNumeric" Source="{Binding}"/> I have one PagedCollectionView pgv which is bound to outer datagrid as: DataContext = pgv; When the row is clicked I set the child datagrid's ItemsSource property to another PagedCollectionView. My problem is it works fine except for the first row for the first time. When I click on it, it doesn't fire the dgData_RowDetailsVisibilityChanged event. Also, when I click on second row, firstly first row fires the event and then the second row fires it and shows the nested grid. Please help.

  • Where to change data for a "list" datasource in dashcode?

    - by erotsppa
    I created a new project in dashcode and it automatically generated a mobile web app for me with a list and sample datasources. I see two datasources, one is labeled as "datasource" and the other is "list". However I can see that the actual data in datasources is in a js file, everything is good but where is the actual data stored for "list"? The sample application came with a bunch of data for "list" and I am unable to change it. Any ideas?

  • A bug in grpah while using google visualization API on IE

    - by gili
    Hi, i'm using google visulization API to build a line chart grapgh. it works fine on FF and Chrome but i'm having problems on IE7: the problem is that the scailing of the x-axis (string) and y-axis (integer) is all wrong. both axis have the same values for some reason, but naturally those valuse are wrong. my code is the following one: var data = new google.visualization.DataTable(); data.addColumn('string', 'Date'); data.addColumn('number', '??????? ???? ??????'); data.addColumn('number', '??????? ??????'); data.addColumn('number', '??????'); data.addColumn('number', '???????'); data.addColumn('number', '???????'); var n = userRightGuessArray.length; data.addRows(userRightGuessArray.length); data.setCell(0, 0, '?? ?????? ??'); data.setCell(0, 1, 0); data.setCell(0, 2, 0); data.setCell(0, 3, 0); data.setCell(0, 4, 0); data.setCell(0, 5, 0); for(var t = 1 ; t // Create and draw the visualization. var chart = new google.visualization.ImageLineChart(document.getElementById('line_div')); chart.draw(data, {width: 400,legend: 'top'/showValueLabels:false/}); thank you for your help, Gili

  • MIPS assembly: how to declare integer values in the .data section?

    - by Barney
    I'm trying to get my feet wet with MIPS assembly language using the MARS simulator. My main problem now is how do I initialize a set of memory locations so that I can access them later via assembly language instructions? For example, I want to initialize addresses 0x1001000 - 0x10001003 with the values 0x99, 0x87, 0x23, 0x45. I think this can be done in the data declaration (.data) section of my assembly program but I'm not sure of the syntax. Is this possible? Alternatively, in the .data section, how do I specify storing the integer values in some memory location (I don't care where, but I just want to reference them somewhere). So I'm looking for the C equivalent of "int x = 20, y=30, z=90;" I know how to do that using MIPS instructions but is it possible to declare something like that in the .data section of a MIPS assembly program?

  • Cfsearch in combination of documents and indexed query data?

    - by Bart B
    hi! I have an application which stores all kind of data about people. The current cfsearch functionality (in Verity) includes searching documents that are attached to these people. If i have 2 documents attached to 1 person, 1 with say ABC in it and the other with XYZ in it, my ideal searchresult for "ABC AND XYZ" would return the 1 person. But as both 'words' are indexed in different documents, the standard behaviour is not to return any result from the cfsearch, because the combination doesnt exist in any of the 2 documents. Is there any way to combine indexed documents and/or query data in a way that the search is executed in the combination of relevant docs and data? In my application that would mean that i could index all documents and data regarding people and have an intelligent 'global' search to find the right person. any pointers and help very much appreciated! (should Solr offer new possibilities in comparison to Verity, no problem!) thanks! Bart

  • Is it a good object-oriented-design practice to send a pointer to private data to another class?

    - by Denis
    Hello everyone, There is well known recommendation not to include into class interface method that returns a pointer (or a reference) to private data of the class. But what do you think about public method of a class that sends to another class a pointer to the private data of the first one. For example: class A { public: void fA(void) {_b.fB(&_var)}; private: B _b; int _var; }; I think that it is some sort of data hiding damage: the private data define state of their own class, so why should one class delegate changes of its own state to another one? What do you think? Denis

  • Unable to display data in a WPF datagrid that has a DataView instance as the items source

    - by Jimmy W
    I am using a DataGrid object from the WPF toolkit. I am binding the DataGrid object to the default view of a DataTable instance as declared in the following code: WeatherGrid.ItemsSource = weatherDataTable.DefaultView; weatherDataTable has three columns. The first column is defined to contain a string data type. The other two columns are defined to contain double data types. When the application exits the function that calls the binding as expressed in the declaration, The DataGrid object displays data for the first column, but not the other columns. When I type the following in the immediate window in the debugger: ((DataRowView)WeatherGrid.Items[0]).Row[1] I get a number, but this doesn't correspond with what is being displayed. Why is only the first column visible, and how can I get all of the data to be visible? I'll leave my XAML definition for the DataGrid object below: <toolkit:DataGrid Margin="12.726,77.71,12,0" Name="WeatherGrid" Height="500" Grid.Row="1" VerticalAlignment="Top" CanUserAddRows="False" CanUserDeleteRows="False" IsReadOnly="True" />

  • python: what are efficient techniques to deal with deeply nested data in a flexible manner?

    - by AlexandreS
    My question is not about a specific code snippet but more general, so please bear with me: How should I organize the data I'm analyzing, and which tools should I use to manage it? I'm using python and numpy to analyse data. Because the python documentation indicates that dictionaries are very optimized in python, and also due to the fact that the data itself is very structured, I stored it in a deeply nested dictionary. Here is a skeleton of the dictionary: the position in the hierarchy defines the nature of the element, and each new line defines the contents of a key in the precedent level: [AS091209M02] [AS091209M01] [AS090901M06] ... [100113] [100211] [100128] [100121] [R16] [R17] [R03] [R15] [R05] [R04] [R07] ... [1263399103] ... [ImageSize] [FilePath] [Trials] [Depth] [Frames] [Responses] ... [N01] [N04] ... [Sequential] [Randomized] [Ch1] [Ch2] Edit: To explain a bit better my data set: [individual] ex: [AS091209M02] [imaging session (date string)] ex: [100113] [Region imaged] ex: [R16] [timestamp of file] ex [1263399103] [properties of file] ex: [Responses] [regions of interest in image ] ex [N01] [format of data] ex [Sequential] [channel of acquisition: this key indexes an array of values] ex [Ch1] The type of operations I perform is for instance to compute properties of the arrays (listed under Ch1, Ch2), pick up arrays to make a new collection, for instance analyze responses of N01 from region 16 (R16) of a given individual at different time points, etc. This structure works well for me and is very fast, as promised. I can analyze the full data set pretty quickly (and the dictionary is far too small to fill up my computer's ram : half a gig). My problem comes from the cumbersome manner in which I need to program the operations of the dictionary. I often have stretches of code that go like this: for mk in dic.keys(): for rgk in dic[mk].keys(): for nk in dic[mk][rgk].keys(): for ik in dic[mk][rgk][nk].keys(): for ek in dic[mk][rgk][nk][ik].keys(): #do something which is ugly, cumbersome, non reusable, and brittle (need to recode it for any variant of the dictionary). I tried using recursive functions, but apart from the simplest applications, I ran into some very nasty bugs and bizarre behaviors that caused a big waste of time (it does not help that I don't manage to debug with pdb in ipython when I'm dealing with deeply nested recursive functions). In the end the only recursive function I use regularly is the following: def dicExplorer(dic, depth = -1, stp = 0): '''prints the hierarchy of a dictionary. if depth not specified, will explore all the dictionary ''' if depth - stp == 0: return try : list_keys = dic.keys() except AttributeError: return stp += 1 for key in list_keys: else: print '+%s> [\'%s\']' %(stp * '---', key) dicExplorer(dic[key], depth, stp) I know I'm doing this wrong, because my code is long, noodly and non-reusable. I need to either use better techniques to flexibly manipulate the dictionaries, or to put the data in some database format (sqlite?). My problem is that since I'm (badly) self-taught in regards to programming, I lack practical experience and background knowledge to appreciate the options available. I'm ready to learn new tools (SQL, object oriented programming), whatever it takes to get the job done, but I am reluctant to invest my time and efforts into something that will be a dead end for my needs. So what are your suggestions to tackle this issue, and be able to code my tools in a more brief, flexible and re-usable manner?

  • How do I display grouped XML data in a Flex pie chart?

    - by mclaughlinj
    I've looked into grouping XML data with GroupingCollections and AdvancedDataGrids, but I can't figure out how to display that data in a chart. Basically, what I want to do is group the data by the category field, which should give me two rows under red, one under blue, and one under green. When inputting this data into the pie chart, it should take up the right amount of space (1/2 for red, 1/4 each for blue and green). I don't need the other_data field, as I'd like to use the group name (category in this case) as the callout. Any suggestions? Sample data: <row> <category>red</category> <other_data>this shouldn't really matter</other_data> </row> <row> <category>blue</category> <other_data>this shouldn't really matter</other_data> </row> <row> <category>red</category> <other_data>this shouldn't really matter</other_data> </row> <row> <category>green</category> <other_data>this shouldn't really matter</other_data> </row>

  • How can I read a DBF file with incorrectly defined column data types using ADO.NET?

    - by Jason
    I have a several DBF files generated by a third party that I need to be able to query. I am having trouble because all of the column types have been defined as characters, but the data within some of these fields actually contain binary data. If I try to read these fields using an OleDbDataReader as anything other than a string or character array, I get an InvalidCastException thrown, but I need to be able to read them as a binary value or at least cast/convert them after they are read. The columns that actually DO contain text are being returned as expected. For example, the very first column is defined as a character field with a length of 2 bytes, but the field contains a 16-bit integer. I have written the following test code to read the first column and convert it to the appropriate data type, but the value is not coming out right. The first row of the database has a value of 17365 (0x43D5) in the first column. Running the following code, what I end up getting is 17215 (0x433F). I'm pretty sure it has to do with using the ASCII encoding to get the bytes from the string returned by the data reader, but I'm not sure of another way to get the value into the format that I need, other that to write my own DBF reader and bypass ADO.NET altogether which I don't want to do unless I absolutely have to. Any help would be greatly appreciated. byte[] c0; int i0; string con = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\ASTM;Extended Properties=dBASE III;User ID=Admin;Password=;"; using (OleDbConnection c = new OleDbConnection(con)) { c.Open(); OleDbCommand cmd = c.CreateCommand(); cmd.CommandText = "SELECT * FROM astm2007"; OleDbDataReader dr = cmd.ExecuteReader(); while (dr.Read()) { c0 = Encoding.ASCII.GetBytes(dr.GetValue(0).ToString()); i0 = BitConverter.ToInt16(c0, 0); } dr.Dispose(); }

  • PDO bindparam not working.

    - by jim
    I am trying to save data into a database using PDO. All columns save correctly with the exception of one. No matter what I try, I cannot get the data to go in. myfunc($db, $data) { echo $data; // <----- Outputs my data. example: 'jim jones' $stmt = $db->prepare("CALL test(:id, :data, :ip, :expires)"); $stmt->bindParam(':id', $id, PDO::PARAM_STR); $stmt->bindParam(':data', $data, PDO::PARAM_STR); $stmt->bindParam(':ip', $ip, PDO::PARAM_STR); $stmt->bindParam(':expires', $expires, PDO::PARAM_STR); ... } So even after verifying that the data variable in fact holds my data, the bindParam method will not bind. When I echo the data variable, I can see the data is there. It will not save though. If I copy the echo'd output of the data variable to screen and paste it into a new variable, it WILL save. I'm at this now for a couple of hours. Can someone please have a look? EDIT: I want to also mention that I have tried using bindValue() in place of bindParam() and the data for the data variable will still not save.

  • What is stopping data flow with .NET 3.5 asynchronous System.Net.Sockets.Socket?

    - by TonyG
    I have a .NET 3.5 client/server socket interface using the asynchronous methods. The client connects to the server and the connection should remain open until the app terminates. The protocol consists of the following pattern: send stx receive ack send data1 receive ack send data2 (repeat 5-6 while more data) receive ack send etx So a single transaction with two datablocks as above would consist of 4 sends from the client. After sending etx the client simply waits for more data to send out, then begins the next transmission with stx. I do not want to break the connection between individual exchanges or after each stx/data/etx payload. Right now, after connection, the client can send the first stx, and get a single ack, but I can't put more data onto the wire after that. Neither side disconnects, the socket is still intact. The client code is seriously abbreviated as follows - I'm following the pattern commonly available in online code samples. private void SendReceive(string data) { // ... SocketAsyncEventArgs completeArgs; completeArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnSend); clientSocket.SendAsync(completeArgs); // two AutoResetEvents, one for send, one for receive if ( !AutoResetEvent.WaitAll(autoSendReceiveEvents , -1) ) Log("failed"); else Log("success"); // ... } private void OnSend( object sender , SocketAsyncEventArgs e ) { // ... Socket s = e.UserToken as Socket; byte[] receiveBuffer = new byte[ 4096 ]; e.SetBuffer(receiveBuffer , 0 , receiveBuffer.Length); e.Completed += new EventHandler<SocketAsyncEventArgs>(OnReceive); s.ReceiveAsync(e); // ... } private void OnReceive( object sender , SocketAsyncEventArgs e ) {} // ... if ( e.BytesTransferred > 0 ) { Int32 bytesTransferred = e.BytesTransferred; String received = Encoding.ASCII.GetString(e.Buffer , e.Offset , bytesTransferred); dataReceived += received; } autoSendReceiveEvents[ SendOperation ].Set(); // could be moved elsewhere autoSendReceiveEvents[ ReceiveOperation ].Set(); // releases mutexes } The code on the server is very similar except that it receives first and then sends a response - the server is not doing anything (that I can tell) to modify the connection after it sends a response. The problem is that the second time I hit SendReceive in the client, the connection is already in a weird state. Do I need to do something in the client to preserve the SocketAsyncEventArgs, and re-use the same object for the lifetime of the socket/connection? I'm not sure which eventargs object should hang around during the life of the connection or a given exchange. Do I need to do something, or Not do something in the server to ensure it continues to Receive data? The server setup and response processing looks like this: void Start() { // ... listenSocket.Bind(...); listenSocket.Listen(0); StartAccept(null); // note accept as soon as we start. OK? mutex.WaitOne(); } void StartAccept(SocketAsyncEventArgs acceptEventArg) { if ( acceptEventArg == null ) { acceptEventArg = new SocketAsyncEventArgs(); acceptEventArg.Completed += new EventHandler<SocketAsyncEventArgs>(OnAcceptCompleted); } Boolean willRaiseEvent = this.listenSocket.AcceptAsync(acceptEventArg); if ( !willRaiseEvent ) ProcessAccept(acceptEventArg); // ... } private void OnAcceptCompleted( object sender , SocketAsyncEventArgs e ) { ProcessAccept(e); } private void ProcessAccept( SocketAsyncEventArgs e ) { // ... SocketAsyncEventArgs readEventArgs = new SocketAsyncEventArgs(); readEventArgs.SetBuffer(dataBuffer , 0 , Int16.MaxValue); readEventArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnIOCompleted); readEventArgs.UserToken = e.AcceptSocket; dataReceived = ""; // note server is degraded for single client/thread use // As soon as the client is connected, post a receive to the connection. Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs); if ( !willRaiseEvent ) this.ProcessReceive(readEventArgs); // Accept the next connection request. this.StartAccept(e); } private void OnIOCompleted( object sender , SocketAsyncEventArgs e ) { // switch ( e.LastOperation ) case SocketAsyncOperation.Receive: ProcessReceive(e); // similar to client code // operate on dataReceived here case SocketAsyncOperation.Send: ProcessSend(e); // similar to client code } // execute this when a data has been processed into a response (ack, etc) private SendResponseToClient(string response) { // create buffer with response // currentEventArgs has class scope and is re-used currentEventArgs.SetBuffer(sendBuffer , 0 , sendBuffer.Length); Boolean willRaiseEvent = currentClient.SendAsync(currentEventArgs); if ( !willRaiseEvent ) ProcessSend(currentEventArgs); } A .NET trace shows the following when sending ABC\r\n: Socket#7588182::SendAsync() Socket#7588182::SendAsync(True#1) Data from Socket#7588182::FinishOperation(SendAsync) 00000000 : 41 42 43 0D 0A Socket#7588182::ReceiveAsync() Exiting Socket#7588182::ReceiveAsync() - True#1 And it stops there. It looks just like the first send from the client but the server shows no activity. I think that could be info overload for now but I'll be happy to provide more details as required. Thanks!

  • best mysql field setup to have a "couples" member profile data saving.

    - by acctman
    Couple database profile entry, which would be the best way to save data. Also the data will be retrieved via php coding and if it could be down with one query code that would be ideal. Within the site_member table create multiple field for each field... ex: m_firstname1, m_firstname2, m_age1, m_age2, etc... Store the couple member data in one field each... and separate with a comma in the data field ex: m_firstname (Mike, Sherry) Create a separate table site_member_c duplicating the same fields that are in site_member table. This is roughly about 10 fields

  • Is there anyway of making json data readable by a Google spider?

    - by leeand00
    Is it possible to make JSON data readable by a Google spider? Say for instance that I have a JSON feed that contains the data for an e-commerce site. This JSON data is used to populate a human-readable page in the users browser. (I.E. The translation from JSON data to human displayed page is done inside the users browser; not my choice, just what I've been given to work with, its an old legacy CGI application and not an actual server-side scripting language.) My concern here is that, the google spiders will not be able to pickup/directly link to the item in question when a user clicks on it in google, being presented with an index page full of all the items, rather than being linked directly to the item they clicked on. Is there anyway of "informing" the google spider in the JSON that what they should feed the user a different link?

  • Python OOP and lists

    - by Mikk
    Hi, I'm new to Python and it's OOP stuff and can't get it to work. Here's my code: class Tree: root = None; data = []; def __init__(self, equation): self.root = equation; def appendLeft(self, data): self.data.insert(0, data); def appendRight(self, data): self.data.append(data); def calculateLeft(self): result = []; for item in (self.getLeft()): if (type(item) == type(self)): data = item.calculateLeft(); else: data = item; result.append(item); return result; def getLeft(self): return self.data; def getRight(self): data = self.data; data.reverse(); return data; tree2 = Tree("*"); tree2.appendRight(44); tree2.appendLeft(20); tree = Tree("+"); tree.appendRight(4); tree.appendLeft(10); tree.appendLeft(tree2); print(tree.calculateLeft()); It looks like tree2 and tree are sharing list "data"? At the moment I'd like it to output something like [[20,44], 10, 4], but when I tree.appendLeft(tree2) I get RuntimeError: maximum recursion depth exceeded, and when i even won't appendLeft(tree2) it outputs [10, 20, 44, 4] (!!!). What am I missing here? I'm using Portable Python 3.0.1. Thank you
