  • Python - output from functions?

    - by Seafoid
    Hi I have a very rudimentary question. Assume I call a function, e.g., def foo(): x = 'hello world' How do I get the function to return x in such a way that I can use it as the input for another function or use the variable within the body of a program? When I use return and call the variable within another functions I get a NameError. Thanks, S :-)

  • Real-time equalizer for all audio on computer

    - by greye
    Is it possible to capture all the sound from a computer and have it pass through a equalizer before reaching the speakers? How can you program a band pass filter on it? EDIT: I'm trying to get this on Windows (with Python? heh) but if there is a generic, cross-platform approach that would be great.

  • Running cruise control.net under different credentials

    - by zachary
    So I have one part of my build that requires domain rights and does file copying. Another part of my build runs some program that requires the user to interact with the desktop which seem to be only accomplish able by the system account. What is the best way to work around these two items? At the moment it seems like I can only do one or the other...

  • g++ -fsyntax-only unit test

    - by anon
    I'm trying to figure out if g++ -fsyntax-only does only syntax checking or if it expands templates too. Thus, I ask stack overflow for help: is there to write a program so that syntactically it's valid, but when template expansion is done, an error occurs? Thanks!

  • "ejb not bound" -- What could be the problem?

    - by Bernhard V
    Hi! When I'm running my program, I get the following error: ... nested exception is javax.naming.NameNotFoundException: ejb not bound The error occurs at the start up when Java wants to create a certain bean. The Bean is a SimpleRemoteStatelessSessionProxyFactoryBean. Could it be that I ain't got the rights to access the naming provider URL although I can ping it? When accessing the bean on my local JBoss there are no problems.

Thanks class Program { static void Main(string[] args) { Console.WriteLine("Hello world"); Console.ReadLine(); } }

  • Java - Layering issues with Lists and Graphics2D

    - by Mirrorcrazy
    So I have a DisplayPanel class that extends JPanel and that also paints my numerous images for my program using Graphics2D. In order to be able to easily customly use this I set it up so that every time the panel is repainted it uses a List, that I can add to or remove from as the program processes. My problem is with layering. I've run into an issue where the List must have reached its resizing point (or something whacky like that) and so the images i want to display end up beneath all of the other images already on the screen. I've come to the community for an answer because I have faith you will provide a good one. DisplayPanel: package earthworm; import java.awt.Graphics; import java.awt.Graphics2D; import java.util.ArrayList; import java.util.List; import javax.swing.JPanel; public class DisplayPanel extends JPanel { private List<ImageMap> images = new ArrayList(); public DisplayPanel() { setSize(800, 640); refresh(); } public void refresh() { revalidate(); repaint(); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; g2d.clearRect(0, 0, 800, 640); for(int i = 0; i < images.size(); i++) g2d.drawImage( images.get(i).getImage(), images.get(i).getX(), images.get(i).getY(), null); } public void paintImage(ImageMap[] images, ImageMap[] clearImages, boolean clear) { if(clear) this.images.clear(); else if(clearImages!=null) for(int i = 0; i < clearImages.length; i++) this.images.remove(clearImages[i]); if(images!=null) for(int i = 0; i<images.length; i++) this.images.add(images[i]); refresh(); } }

  • Solution Output Directory

    - by L.E.O
    The project that I'm currently working on is being developed by multiple teams where each team is responsible for different part of the project. They all have set up their own C# projects and solutions with configuration settings specific to their own needs. However, now we need to create another, global solution, which will combine and build all projects into the same output directory. The problem that I have encountered though, is that I have found only one way to make all projects build into the same output directory - I need to modify configurations for all of them. That is what we would like to avoid. We would prefer that all these projects had no knowledge about this "global" solution. Each team must retain possibility to work just with their own sub-solution. One possible workaround is to create a special configuration for all projects just for this "global" solution, but that could create extra problems since now you have to constantly sync this configuration settings with the regular one, used by that specific team. Last thing we want to do is to spend hours trying to figure out why something doesn't work when building under global solution just because of some check box that developers have checked in their configuration, but forgot to do so in the global configuration. So, to simplify, we need some sort of output directory setting or post build event that would only be present when building from that global, all-inclusive solution. Is there any way to achieve this without changing something in projects configurations? Update 1: Some extra details I guess I need to mention: We need this global solution to be as close as possible to what the end user gets when he installs our application, since we intend to use it for debugging of the entire application when we need to figure out which part of the application isn't working before sending this bug to the team working on that part. This means that when building under global solution the output directory hierarchy should be the same as it would be in Program Files after installation, so that if, for example, we have Program Files/MyApplication/Addins folder which contains all the addins developed by different teams, we need the global solution to copy the binaries from addins projects and place them in the output directory accordingly. The thing is, the team developing an addin doest necessary know that it is an addin and that it should be placed in that folder, so they cannot change their relative output directory to be build/bin/Debug/Addins.

  • Pass parameters to Flash Main (Document) class

    - by loto
    In Flash CSn/AS3 you associate a Main class with a flash file which when loaded in the flash player "automatically creates an instance of the program's main class." I'd like to know how to pass arguments to the main class, since you don't write it yourself (you put its name in the Document textfield in the IDE).

  • UI Thread .Invoke() causing handle leak?

    - by JYelton
    In what circumstances would updating a UI control from a non-UI thread could cause the processes' handles to continually increase, when using a delegate and .InvokeRequired? For example: public delegate void DelegateUIUpdate(); private void UIUpdate() { if (someControl.InvokeRequired) { someControl.Invoke(new DelegateUIUpdate(UIUpdate)); return; } // do something with someControl } When this is called in a loop or on timer intervals, the handles for the program consistently increase.

  • bash "map" equivalent: run command on each file

    - by Claudiu
    I often have a command that processes one file, and I want to run it on every file in a directory. Is there any built-in way to do this? For example, say I have a program data which outputs an important number about a file: ./data foo 137 ./data bar 42 I want to run it on every file in the directory in some manner like this: map data `ls *` ls * | map data to yield output like this: foo: 137 bar: 42

  • [C#] Get a domain name basing on the IP address

    - by Tony
    hi, I need to get a domain name if I have an IP address (e.g. I type 209.85.129.103 and the program should find out that is the Google address) As far as I've figured out is get the hostname: IPHostEntry IpToDomainName = Dns.GetHostEntry("209.85.129.103"); string HostName = IpToDomainName.HostName; //it returns "fk-in-f103.1e100.net" but it's not that I want. I don't know how to achieve that. Any ideas will be helpful

  • Programmatically creating linked tables in access

    - by newtoaccess
    Hi all, We need to find a way to programatically *link all the tables* in a SQL Server database to an access db. We will be invoking this access database from a program that uses .net/SQL Server 2008. While invoking the application we would like to add the linked tables so that the users can just run the reports/modules from access without having to worry about linking the tables. Is there a way we can do this? Thanks!
