  • "TypeError: draw() takes exactly 1 non-keyword argument (3 given)"

    - by Amorack
    I wrote this code to open a window with Pyglet in Python... import pyglet from pyglet import window class Window(pyglet.window.Window): def __init__(self): super(Window, self).__init__() myLabel = pyglet.text.Label("Prototype") windowText = myLabel.draw(Window, "Hello World", font_name = "Times New Roman", font_size = 36, color = (193, 205, 193, 255)) def on_draw(self): self.clear() self.label.draw() if __name__ == '__main__': window = Window() pyglet.app.run() however every time I run it I get this error: TypeError: draw() takes exactly 1 non-keyword argument (3 given) AFAIK the "(3 given)" means the problem is with the font_size or color arguments but I'm not sure. Could someone explain what's wrong and help me make this work?

  • Drag/Drop image url in IE

    - by pierre
    I have a requirement in our web app. to allow users to drag an image from an external site and drop it in a text editor they have open in our app. This is, as you'd expect, to let them embed the image in the document (its a rich text editor). In IE 8 this functionality appears to be broken. If I drag/drop, IE uses a relative URL for the 'src' tag on the image - which means I cannot then download the file and store it since I dont know the full address (eg: '../../imgs/myImage.png') Safari and Firefox do not do this; they provides the fully-qualified address (eg: www.mysite.com/imgs/myImage.png). Is this a bug in IE or just WebKit/Mozilla going the extra mile?

  • run .net consolapp out of a cgi script

    - by Nico
    Hello there, i have written a simple cgi python script which looks like this #!c:/Python25/python.exe -u import cgi import os def main(): print "Content-type: text/html\n" form = cgi.FieldStorage() print form["firstname"].value os.execvp("D:\\path\\to\\my\\consolapp.exe", [""]) main() As you can se i'd like to start a consoleapp which i have written in .net. But my consoleapp crashs when i call the cgi script. So i did a little debuging and write a text file after some actions i do in my .net program. The result was that my programm crash everytime i'd like to open a access mdb file. It told me that i need the Microsoft Data Access Components (MDAC). But i cant belive this message because my .net consoleapp runs without errors if i start it from my own. So can anybody give me some advise how i can call my .net consol ab through a webscript. I'm happy for every advise So it don't have to be a solution using a cgi script. Regards, Nico

  • Rosetta Stone: Great example projects

    - by Adam Bellaire
    In your opinion, what is a great example application which demonstrates the best techniques for its language and problem domain, and could be used as a reference for other programmers? Please provide answers where the source is readily available for viewing (i.e. open-source projects), and provide a link. The first line of each answer should indicate the language and the problem domain in bold, e.g.: Java - Web Application ... or ... C# - DX Game As with other Rosetta Stone questions, the answers here should demonstrate the language/technology in the example in such a way that programmers who aren't familiar with them can get an impression of what they're like.

  • WPF: Changing config file user settings at runtime?

    - by Poku
    Hey I'm trying to change some config file user settings values in my WPF application, but its only working partly. The value is changed correctly and the program runs fine with the value. I can even restart the program and the value is still the one i changed it to. The problem is that when i open the .exe.config file the value is still the old value. Im using this code to change the value: Properties.Settings.Default.ProjectNumber = varTestExample; Properties.Settings.Default.Save(); Where does this save code save the changes and how/where does the program read the value after i have run this code? If i run a clean version of the program the ProjectNumber value is correctly taken from the .exe.config file and if i change the value in the config file it is also change when i run the program. But as soon as i run the above code the program is not reading the value from the config file. Why?

  • What's viewport mean to the jQuery guys?

    - by justSteve
    I came here intent on asking a 'how do i' type question focused on a particular UI problem i have to solve and i started using the term 'viewport'. Seems there's lots of contexts that tag evokes. Before i outline mine i should ask - is there a generally recognized consensus as to what a 'viewport' is? Any gallery or object browser that focuses on a UI principle where multiple frames/panes show feeds of different graphs where each feed might be a complex grid/graph? I'm imagining something where my page may open with a half dozen different grids (tabular data) stay updated via ajax interactions with various servers. UI elements provide control scale up or down a given grid with a quasi accordion slide kinda thingie. For example, one click on a scale up-or-down control would rescale the other viewports in the opposite direction. More clicks - more pronounced effect. So my 'how do i' question morphs into a 'how have others...' thx

  • TableView as DetailView's subview with a UISplitViewController?

    - by Gerry
    I have a UISplitViewController, I used the iPad template to start. To change the type of view in the detailview area, I'm adding my view types as subviews to the DetailViewController's view. This works for UIViewController derived views, but not for UITableViewController view types?. Why would this be? My problem is rooted in the fact that the manufactured DetailView is the UISplitViewController's delegate. To get the correct popover behaviour, I'd like to keep it add buttons to its toolbar and then based on user selection open different details when master list selections are made. Thanks,

  • OpenGL Wrapper in .Net

    - by Ngu Soon Hui
    This question is similar to the one here. But I feel that the answers recommended ( such as Tao and OpenTK) are not good enough because they are just a direct port from OpenGL, with no OOP design, and hard to use. What I'm looking for is a .Net OpenGL wrapper that is written in clear OOP principles, easy to use ( easy to apply textual and lighting, easy to debug etc), able to rotate the 3D diagram with mouse ( a feature that is critically missing from OpenGL and TAO), and the ability to export to other file formats ( such as dwg or dxf or Google Map file format). Any suggestion? Both Open source or commercial components would do.

  • Middleware for MongoDB or CouchDB with jQuery Ajax/JSON frontend

    - by Tauren
    I've been using the following web development stack for a few years: java/spring/hibernate/mysql/jetty/wicket/jquery For certain requirements, I'm considering switching to a NoSQL datastore with an AJAX frontend. I would probably build the frontend with jQuery and communicate with the web application middleware using JSON. I'm leaning toward MongoDB because of more dynamic query capabilities, but am still considering CouchDB. I'm not sure what to use in the middle. Probably something RESTful? My preference is to stick with Java (or maybe Scala or Groovy) since I'm using tools like Drools for rules and Shiro for security. But then again, I want to pick something that is quick an easy to work with, so I'm open to other solutions. If you are building ajax/json/nosql solutions, I'd like to hear details about what tools you are using and any pros/cons you've found to using them. Thanks!

  • Recursively CVS add files/directories and ignore existing CVS files.

    - by meder
    There's a similar post @ http://stackoverflow.com/questions/5071/how-to-add-cvs-directories-recursively However, trying out some of the answers such as: find . -type f -print0| xargs -0 cvs add Gave: cvs add: cannot open CVS/Entries for reading: No such file or directory cvs [add aborted]: no repository And find . \! -name 'CVS' -and \! -name 'Entries' -and \! -name 'Repository' -and \! -name 'Root' -print0| xargs -0 cvs add Gave: cvs add: cannot add special file `.'; skipping Does anyone have a more thorough solution to recursively adding new files to a CVS module? It would be great if I could alias it too in ~/.bashrc or something along those lines. And yes, I do know that it is a bit dated but I'm forced to work with it for a certain project otherwise I'd use git/hg.

  • Will an ASP.NET MVC 2 app build with the .NET 4.0 RC and VS2010 RC run on a prod server with the .NE

    - by Chris
    I have an MVC2 app I developed with the VS2010 RC and the .NET 4.0 RC. My production server and my client's production server have .NET 4.0 RC. Can the RTM of .NET 4.0 on a server support an app developed with the RC technologies? What about the other way around? Can I use VS2010 RTM and deploy an app to production if the prod server is still no the .NET 4.0 RC? Obviously it would be ideal to synch everything up to RTM but I don't have that option right now because the client doesn't have access to VS2010 RTM yet, and they would like to be able to open and build the project.

  • Resharper doesn't play well with XAML?

    - by John Weldon
    I've been noticing a pattern with ReSharper (both 4.5 and 5). Very often (almost always) when I have solution-wide analysis turned on, and WPF code in my solution, ReSharper will mark a number of the .xaml.cs files as being broken. When I navigate to the file, sometimes it magically updates and displays no errors, and other times I have to open other files that are not being correctly read and close them again to force resharper to correctly analyze them. I assume it has something to do with the temporary .cs code that is generated with XAML, but does anyone know why this is actually happening, and if there is a work around? Should I just file a bug report with JetBrains? Does anyone else experience this?

  • Database change management tools?

    - by zodeus
    We are currently in the process of solidifying a database change management process. We run MySql 5 running on RedHat 5. I have selected LiquiBase as the tool because it's open source and allows us to expand its functionality later if needed. It also seems to be one of the few free projects that are still active. Has anyone here had any experience using LiquiBase or other Db versioning tools? Company Background: We are an SaaS company providing a 7/24 hosted application. There are dozens of instances running different versions of the same database and we need a way to manage the deploy process as it's starting to get out of control. The databases have hundreds of tables and we typically do releases once every 3 months.

  • Scheme implementations - what does it mean?

    - by JDelage
    Hi, I'm a beginning student in CS, and my classes are mostly in Java. I'm currently going through "Little Schemer" as a self study, and in the process of finding out how to do that I have found numerous references to "implementations" of Scheme. My question is, what are implementations? Are they sub-dialects of Scheme, or is that something else (DrScheme seem to allow for different "flavors" of the language)? Is it just the name given to any given ecosystem incorporating an IDE, interpreter, interactive tool and the like? Do all other languages (e.g., Java) also have a variety of "implementations", or is it something reserved to "open" languages? Thank you, Joss Delage

  • Sparse matrices / arrays in Java

    - by DanM
    I'm working on a project, written in Java, which requires that I build a very large 2-D sparse array. Very sparse, if that makes a difference. Anyway: the most crucial aspect for this application is efficency in terms of time (assume loads of memory, though not nearly so unlimited as to allow me to use a standard 2-D array -- the key range is in the billions in both dimensions). Out of the kajillion cells in the array, there will be several hundred thousand cells which contain an object. I need to be able to modify cell contents VERY quickly. Anyway: Does anyone know a particularly good library for this purpose? It would have to be Berkeley, LGPL or similar license (no GPL, as the product can't be entirely open-sourced). Or if there's just a very simple way to make a homebrew sparse array object, that'd be fine too. I'm considering MTJ, but haven't heard any opinions on its quality. Thanks!! -Dan

  • iphone settings disappear

    - by cagreen
    I have created an app which uses Application Settings and user defaults following the example in the book "Beginning iPhone Development". In some cases my settings seem to disappear. If I launch the simulator I can go into settings and see it, I can then open my app and my settings can be read from within the app. If I then leave my app and go back into the settings screen I can no longer see the settings for my app! I'm new to iPhone dev, is there something obvious that I'm overlooking? Thanks.

  • Question regarding Manifest in Java jar file

    - by Tara Singh
    Hi All, Is is mandatory to have classpath inside a Manifest file inside the java jar file? can we do work without having the classpath inside it? The reason why I am asking this is because I have a jar file for a server application. When I tried to connect many connections with Server, Server went down and the error was "Too many open files", when searched about it, I found one Sun Bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6446657 . Then I checked and i was having a classpath entry in the Jar file. So this question arises. Thanks, Tara Singh

  • How can I create a hybrid Silverlight and aspx application

    - by PilotBob
    Here is my scenerio.. We have an ASP.Net 2.x web site. We want to migrate it to Silverlight full frame application. However, there is no way we can go away in a corner and redo every web page in SL right off the bat. What I would like to do is build the chrome of the app (main page, dashboard, login, common system/config screens, main menu) in SL and be able to open existing .aspx pages in the main content SL frame. From what I see there is no way to do this. I thought the Webbrowser control in SL4 would be the answer, but apparently that only works if your app is run out of browser. So, what is my best recourse? It seems like I will have to create some type of .aspx page that hosts the .XAP and pass in the page I want it to load? How would you gurus approach this?

  • What can I do with Java for Blu Ray or BD-J?

    - by Jay Askren
    I have a Blu Ray player which can connect to the internet to play media from netflix and youtube. I am intrigued by the possibilities of BD-J and wondering just how far the technology can be taken. For instance: Could I write a twitter, facebook, rss reader, or email client? Can I write a game which would allows people to play each other over the web from their own tv? Could I write a DVR app which stored tv shows on the thumbdrive plugged into the player. Can I run my applications from a thumbdrive or do I need to put them on a Blu Ray disk? Does anyone have real experience with BD-J? How do you like it as a development platform? How would you recommend getting started? Can I develop in BD-J using open source tools like Eclipse, Maven, etc...

  • How to configure maximum number of channels in WCF?

How can I configure the maximum number of connections that can be opened using HTTP binding?

  • What is best way to raise application events for use with admin network monitoring tools

    - by J Cooper
    In a semi-critical .NET service application, what would be a good strategy for raising application events that could be monitored by network administration tools? The events would be for errors, status changes, and possibly other notifications. My company is planning to use some kind of tool down the road to monitor all critical machines and services. As of right now they are using Spice Works to do some monitoring but it is not known if they will keep this down the road. By strategy I mean, perhaps using some sort of protocol ( my network admin has mentioned SNMP), perhaps a service such as windows event log. I have no idea what is available, so I'm leaving the options open. With that in mind, here is a list of preferences I came up with: Somewhat easy to use with .NET. Reliability Should work well with a variety of admin monitoring tools Works with non - windows monitoring tools Works with Spice Works

  • NodeJS and node-mongodb-native

    - by w1nk
    Just getting started with node, and trying to get the mongo driver to work. I've got my connection set up, and oddly I can insert things just fine, however calling find on a collection produces craziness. var db = new mongo.Db('things', new mongo.Server('192.168.2.6',mongo.Connection.DEFAULT_PORT, {}), {}); db.open(function(err, db) { db.collection('things', function(err, collection) { // collection.insert(row); collection.find({}, null, function(err, cursor) { cursor.each(function(err, doc) { sys.puts(sys.inspect(doc,true)); }); }); }); }); If I uncomment the insert and comment out the find, it works a treat. The inverse unfortunately doesn't hold, I receive this error: collection.find({}, null, function(err, cursor) { ^ TypeError: Cannot call method 'find' of null I'm sure I'm doing something silly, but for the life of me I can't find it...
