  • How do I create a "jumping" circle in Java GUI?

    - by Roman
    I would like to have a red filled circle at some place in my window. After the click on the circle, the circle should jump from the original place to a new one (disappear from the old place and appear on the new one). What would be the best way to do it? I also would like to know how to draw a filled circle in Java. Are there any simple tools to do it? Or may be the easiest way is to use an image created by some other software?

  • How to create make .so files from code written in c or c++ that are usable from python

    - by None
    Looking at python modules and at code in the "lib-dnyload" directory in the python framework, I noticed whenever code is creating some kind of gui or graphic it imports a non-python file with a .so extension. And there are tons .so files in "lib-dnyload". From googling things I found that these files are called shared objects and are written in c or c++. I have a mac and I use gcc. I want to know how to make shared object files that are accessible via python. Mainly just how to make shared objects with gcc using mac os x.

  • I want to create an expression for querystrings, this stuff is hard!

    - by jkirkerx
    I want to extract some keywords out of a query string for a search application in asp.net. I decoded the url string first, so it's plain text I have this to start with, but I want to add a keyword group I'd like to trim off the stuff for pure words, but not sure if that's possible I also have a long list of possible query string value fields that I want to check against ?q= @q= ?qs= &qs=

  • If I had to create a server farm what should I do? (how others companies work?)

    - by Michel
    I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

  • How to create your own advert engine for an Android App?

    - by Richard Green
    I have an Android App and I would like to start putting non-intrusive advert into the app. However, I have the benefit of knowing exactly what products I would like to put in these adverts (which will basically be amazon "similar products" type things and a few other suppliers). Is there any ad-engine out there that will allow me to do this? The ones I see already just put what they think are suitable. I have scoured and I can't find an example of this... Any ideas? Should I just bite the bullet and write my own classes to do this ?

  • How to use Joomla to allow users to create/update data on my site?

    - by gromo
    Right now Im using an extension called chronoforms but Im open to anything that works. I can make forms just fine, and it saves the submitted data to a table. Where I am stuck is, how do I then allow my front end users who filled out and submitted the form to go back, view their old answers, change them, and resubmit them or resave them. In order to do this I think I would need to be able to retrieve their last answers from the table on which it is stored, replug the last specific data record for that user only back into the original form on the front end and let the user change and resubmit it? Unless there is a better way to allow the user to change their answers to a form and resave them? If anyone knows how to do this, or if there is a better way I should be going about doing this, (perhaps there is another extension that handles this kind of thing) please let me know. Thanks!

  • How do I create a certain control using Windows Forms in Visual C++?

    - by Dalze
    I am new to using Windows Forms in C++ (and just in general), and I am not exactly sure of the name or if it's even possible to do. Currently I am currently working on a school project in which we must make a program for an imaginary bookstore. I am trying right now to make a sort of list that shows what the "customer" is buying. I have to make it sort by price and ISBN and any other variable that the book has. In essence I am trying to make something like the following: I just need to know how to get started. I can't figure out what the name of the control is or how to even get it to sort every time the user clicks on the header.

  • Is there a (C#) library that will create feeds for Amazon Marketplace Web Services?

    - by Josh Kodroff
    Does anyone know of a library out there (preferably in C#) that will take classes and generate XML or flat files suitable for feeds to Amazon Marketplace Web Services? In other words, I'd like to do something like this: var feed = new AmazonProductFeed(); var list = new AmazonProductList(); var product1 = new AmazonProduct(); product1.Name = "Product 1"; list.Add(product1); var product2 = new AmazonProduct(); product2.Name = "Product 2"; list.Add(product2); feed.Products = list; // spits out XML compliant with Amazon's schema Console.Write(feed.ToXml()); It looks like the only code Amazon provides are wrappers for the web service itself and the directory-based transport utility (AMTU).

  • Is it good to create a usercontrol for Recursive code in xaml?

    - by user281947
    <Border BorderBrush="#C4C8CC" BorderThickness="0,0,0,1"> <TextBlock x:Name="SectionTitle" FontFamily="Trebuchet MS" FontSize="14" FontWeight="Bold" Foreground="#3D3D3D" /> </Border> I have to use the same above format at many places in a single xaml page, so for this i created a usercontrol and defined the above code inside it.

  • How do I create a dynamic method in PHP?

    - by sandelius
    I'm trying to extend my ActiveRecord class with some dynamic methods. I would like to be able to run this from my controller $user = User::find_by_username(param); $user = User::find_by_email(param); I've read a little about overloading and think that's the key. I'v got a static $_attributes in my AR class and I get the table name by pluralizing my model (User = users) in this case. How do I do this? All models extends the ActiveRecord class.

  • create child nodes from sibling nodes until a different sibbling occurs.

    - by user364939
    Hi does anyone know what the xsl would look like to transform this XML. There can be N nte's after pid and N nte's after pv1. The structure is guaranteed in that all nte that follows pid belongs to pid and all nte following pv1 belongs to pv1. From: <pid> </pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte></nte> <pv1></pv1> <nte> </nte> into: <pid> <nte> <nte-1>1</nte-1> <nte-3>Note 1</nte-1> </nte> <nte> </nte> </pid> <pv1> <nte> </nte> </pv1> Thanks!
