  • How to find full module path of a class to import in other file

    - by Pooya
    I have method that returns module path of given class name def findModulePath(path, className): attributes = [] for root, dirs, files in os.walk(path): for source in (s for s in files if s.endswith(".py")): name = os.path.splitext(os.path.basename(source))[0] full_name = os.path.splitext(source)[0].replace(os.path.sep, '.') m = imp.load_module(full_name, *imp.find_module(name, [root])) try: attr = getattr(m, className) attributes.append(attr) except: pass if len(attributes) <= 0: raise Exception, "Class %s not found" % className for element in attributes: print "%s.%s" % (element.__module__, className) but it does not return the full path of the module, For example I have a python file named "objectmodel" in objects package,and it contains a Model class, So I call findModulePath(MyProjectPath,"Model"). it prints objectmodel.Model but I need objects.objectmodel.Model

  • sql query question / count

    - by scheibenkleister
    Hi, I have houses that belongs to streets. A user can buy several houses. How do I find out, if the user owns an entire street? street table with columns (id/name) house table with columns (id/street_id [foreign key] owner table with columns (id/house_id/user_id) [join table with foreign keys] So far, I'm using count which returns the result: select count(*), street_id from owner left join house on owner.house_id = house.id group by street_id where user_id = 1 count(*) | street_id 3 | 1 2 | 2 A more general count: select count(*) from house group by street_id returns: count(*) | street_id 3 | 1 3 | 2 How can I find out, that user 1 owns the entire street 1 but not street 2? Thanks.

  • How to handle concurrency control in dynamic data?

    - by Andrew
    I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

  • NoClassDefFoundError points to the wrong class.

    - by Sora
    I'm validating the installation of a program that consists of a few separate modules. They are not co-dependent. I have apple.jar and orange.jar, they are placed in the same folder and were developed in the same project, but run independent of each other. Running apple.jar goes fine, but orange.jar gives me a NoClassDefFoundError pointing to apple.jar. /usr/java/jre1.6.0_14/bin/java -jar validator.jar Exception in thread "main" java.lang.NoClassDefFoundError: orange/client/Apple Caused by: java.lang.ClassNotFoundException: orange.client.Apple at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Could not find the main class: validator/client/StormDataXMLGenerator. Program will exit. The manifest file lists Orange as the correct main class. Main-Class: orange/client/Orange Anybody know why it's giving me the NoClassDefFoundError? Thanks in advance!

  • RedirectStandardInput crashes program

    - by Roman
    Hi, the following code is to open a console application (which uses pdcurses for output, nothing special): myProcess.StartInfo.FileName = "some.exe"; myProcess.StartInfo.UseShellExecute = false; myProcess.StartInfo.CreateNoWindow = false; myProcess.StartInfo.RedirectStandardInput = true; myProcess.Start(); The Problem is that it opens the designated window but directly closes it (it's barely visible). Starting the program without RedirectStandardInput works. The problem is that it does not throw an exception nor any error-message. What is wrong with my code? How can I write input to the program? Thanks.

  • Algorithm to split an array into N groups based on item index (should be something simple)

    - by serg
    I feel that it should be something very simple and obvious but just stuck on this for the last half an hour and can't move on. All I need is to split an array of elements into N groups based on element index. For example we have an array of 30 elements [e1,e2,...e30], that has to be divided into N=3 groups like this: group1: [e1, ..., e10] group2: [e11, ..., e20] group3: [e21, ..., e30] I came up with nasty mess like this for N=3 (pseudo language, I left multiplication on 0 and 1 just for clarification): for(i=0;i<array_size;i++) { if(i>=0*(array_size/3) && i<1*(array_size/3) { print "group1"; } else if(i>=1*(array_size/3) && i<2*(array_size/3) { print "group2"; } else if(i>=2*(array_size/3) && i<3*(array_size/3) print "group3"; } } But what would be the proper general solution? Thanks.

  • Help Me Understand C++ Header files and Classes

    - by JamesW
    OK, So I am trying to transition from intermediate Delphi to C++ Object Oriented programing. I have read Ivar Horton's book on visual C++ 2010. I can pull off the simple console applications no problem. I get the language itself (kinda). Where I am struggling is with headers and classes. I also understand what header files and classes do in general. What I am not getting is the implementation when do I use a header or a class? Do I need to create classes for everything I do? Do my actual work functions need to be in header files or in CPP files? I'm lost on the proper uses of these and could use some real world guidance from more experienced programmers. I am trying to transition to windows applications using the MFC if that is helpful.

    - by Imran
    I find myself constantly learning new things in web development and there is always soo much to learn in general.

  • Audio Player with Custom Buttons

    - by Bryan Wong
    I am developing a website but require help regarding a simple javascript audio player. Currently, I have four divs set up as the "buttons" : previous song; pause; play; and next song. Pretty much self explanatory, each button serves its obvious function, previous song, pause the song, play the song, and next song. With this in mind, I am also hoping to have the music start playing right after the page completes loading. I understand there are numerous javascript solutions that involve the use of third-party "applications" such as jplayer, however, I am not well learned in javascript and would like to request the aid of the general body in this matter. LOL. that was awkwardly formal. Um, but yes. I am looking for a way to use my four divs as the controllers of a multi-track audio player. Thanks,

  • Best practice for string substition with gettext using Python

    - by Malcolm
    Looking for best practice advice on what string substitution technique to use when using gettext(). Or do all techniques apply equally? I can think of at least 3 string techniques: Classic "%" based formatting: "My name is %(name)s" % locals() .format() based formatting: "My name is {name}".format( locals() ) string.Template.safe_substitute() import string template = string.Template( "My name is ${name}" ) template.safe_substitute( locals() ) The advantage of the string.Template technique is that a translated string with with an incorrectly spelled variable reference can still yield a usable string value while the other techniques unconditionally raise an exception. The downside of the string.Template technique appears to be the inability for one to customize how a variable is formatted (padding, justification, width, etc).

  • Running NUnit Tests from Code

    - by Dror Helper
    I'm trying to write a simple method that receives a file an runs it using NUnit. The code I managed to build using NUnit's source does not work: if(openFileDialog1.ShowDialog() != DialogResult.OK) { return; } var builder = new TestSuiteBuilder(); var testPackage = new TestPackage(openFileDialog1.FileName); var directoryName = Path.GetDirectoryName(openFileDialog1.FileName); testPackage.BasePath = directoryName; var suite = builder.Build(testPackage); TestResult result = suite.Run(new NullListener(), TestFilter.Empty); The problem is that I keep getting an exception thrown by builder.Build stating that the assembly was not found. What am I missing?

  • Mapping words to numbers with respect to definition

    - by thornate
    As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

  • Property in a Windows Forms form class only accessable after Load event

    - by Spooky2010
    I'm instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ?

  • I Clean Solution'd my Winform App and now it's broken...

    - by Refracted Paladin
    I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -- Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded also if I try to open a form or user control in Design Mode I first get this -- could not find type, "MyType" please make sure that the assembly that contains this type is referenced and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode -- Exception of type System.OutOfMemoryException was thrown Help!?!? When I googled I came across mostly references to VS 2003...I am on 2008 sp1.

  • Database file is inexplicably locked during SQLite commit

    - by sweeney
    Hello, I'm performing a large number of INSERTS to a SQLite database. I'm using just one thread. I batch the writes to improve performance and have a bit of security in case of a crash. Basically I cache up a bunch of data in memory and then when I deem appropriate, I loop over all of that data and perform the INSERTS. The code for this is shown below: public void Commit() { using (SQLiteConnection conn = new SQLiteConnection(this.connString)) { conn.Open(); using (SQLiteTransaction trans = conn.BeginTransaction()) { using (SQLiteCommand command = conn.CreateCommand()) { command.CommandText = "INSERT OR IGNORE INTO [MY_TABLE] (col1, col2) VALUES (?,?)"; command.Parameters.Add(this.col1Param); command.Parameters.Add(this.col2Param); foreach (Data o in this.dataTemp) { this.col1Param.Value = o.Col1Prop; this. col2Param.Value = o.Col2Prop; command.ExecuteNonQuery(); } } this.TryHandleCommit(trans); } conn.Close(); } } I now employ the following gimmick to get the thing to eventually work: private void TryHandleCommit(SQLiteTransaction trans) { try { trans.Commit(); } catch (Exception e) { Console.WriteLine("Trying again..."); this.TryHandleCommit(trans); } } I create my DB like so: public DataBase(String path) { //build connection string SQLiteConnectionStringBuilder connString = new SQLiteConnectionStringBuilder(); connString.DataSource = path; connString.Version = 3; connString.DefaultTimeout = 5; connString.JournalMode = SQLiteJournalModeEnum.Persist; connString.UseUTF16Encoding = true; using (connection = new SQLiteConnection(connString.ToString())) { //check for existence of db FileInfo f = new FileInfo(path); if (!f.Exists) //build new blank db { SQLiteConnection.CreateFile(path); connection.Open(); using (SQLiteTransaction trans = connection.BeginTransaction()) { using (SQLiteCommand command = connection.CreateCommand()) { command.CommandText = DataBase.CREATE_MATCHES; command.ExecuteNonQuery(); command.CommandText = DataBase.CREATE_STRING_DATA; command.ExecuteNonQuery(); //TODO add logging } trans.Commit(); } connection.Close(); } } } I then export the connection string and use it to obtain new connections in different parts of the program. At seemingly random intervals, though at far too great a rate to ignore or otherwise workaround this problem, I get unhandled SQLiteException: Database file is locked. This occurs when I attempt to commit the transaction. No errors seem to occur prior to then. This does not always happen. Sometimes the whole thing runs without a hitch. No reads are being performed on these files before the commits finish. I have the very latest SQLite binary. I'm compiling for .NET 2.0. I'm using VS 2008. The db is a local file. All of this activity is encapsulated within one thread / process. Virus protection is off (though I think that was only relevant if you were connecting over a network?). As per Scotsman's post I have implemented the following changes: Journal Mode set to Persist DB files stored in C:\Docs + Settings\ApplicationData via System.Windows.Forms.Application.AppData windows call No inner exception Witnessed on two distinct machines (albeit very similar hardware and software) Have been running Process Monitor - no extraneous processes are attaching themselves to the DB files - the problem is definitely in my code... Does anyone have any idea whats going on here? I know I just dropped a whole mess of code, but I've been trying to figure this out for way too long. My thanks to anyone who makes it to the end of this question! brian UPDATES: Thanks for the suggestions so far! I've implemented many of the suggested changes. I feel that we are getting closer to the answer...however... The code above technically works however it is non-deterministic! It is not guaranteed to do anything aside from spin in neutral forever. In practice it seems to work somewhere between the 1st and 10th iteration. If i batch my commits at a reasonable interval damage will be mitigated but I really do not want to leave things in this state... More suggestions welcome!

  • Converting a navbar to a tabbar app

  • How to JSON serialize math vector type in F#?

    - by The_Ghost
    Hello! I'm trying to serialize "vector" (Microsoft.FSharp.Math) type. And I get that error: Exception Details: System.Runtime.Serialization.SerializationException: Type 'Microsoft.FSharp.Math.Instances+FloatNumerics@115' with data contract name 'Instances.FloatNumerics_x0040_115:http://schemas.datacontract.org/2004/07/Microsoft.FSharp.Math' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer. I have tried to put KnownType attribute and some other stuff, but nothing helps! Could someone know the answer?

  • getResourceAsStream not loading resource in webapp

    - by mangst
    I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.
