  • Code jumps out of a jar and runs? What is causing this?

    - by Mike
    I am trying to get a sample program working with JUNG, a graphing tool in Java. I downloaded and referenced all the .jar files in eclipse so my project hierarchy looks like this: In Test.java I have the following code: public class Test { static public void main() { System.out.print("Hello"); }} For some reason though when I try to run it as a Java Application by right clicking on Jung test in the project hierarchy I am presented with a bunch of classes. My Test.java isn't on the list so if I just leave it as ** and press ok it starts running a program that is dynamically adding nodes and vertexes to a graph. I can't seem to figure out what code its actually executing. I know java but stuff like this with the jar files seems to be getting lost on me. Any ideas? Thanks

  • Forbid GridView to load all views at once

    - by efpies
    I have about 700 items to display in the grid view. On a Samsung Galaxy Tab 10.1 this is not a problem: it has enough memory. On a HTC Explorer the heap is overflown. So I want to load data dynamically regarding current scroll position (N rows for screen + 5 rows as a tail). And I want to show a scrollbar which represents the position in total rows. But I don't want to draw items that I don't see. In other words, I want to create something similar to UITableView in iOS. How can I do this?

  • AutoComplete and VS2010 Internal WebDevServer caching ?

    - by Renshai
    Ok this is a simple setup: DB has a view with personnel who have not been added to the system. The AutoComplete dynamically lists a numeric column field from the view. (Using Linq2SQL) (with autotracking off) Once this number is consumed - a refresh is done on the sqlserver's view. The Problem: This number still shows up in the Autocomplete UNTIL the VS WebDev Server is closed. Question: Why is the WebDev caching the data? I have tried turning off viewstate of the textbox, turned off caching on the autocompleteextender, to no avail. Any help please ...

  • How do I route watir through a proxy pragmatically?

    - by feydr
    I'm trying to route watir through a proxy pragmatically -- this means within the script I'd like to change my proxy dynamically before launching the browser. Here's what I've tried so far (and so far am failing): I'm running chrome and lucid lynx ubuntu. I chose TREX cause I thought watir might be making use of PROXY or something. I rewrote /usr/bin/google-chrome as: #!/bin/bash /opt/google/chrome/chrome --proxy-server="$TREX" $@ The reason I'm passing in the environment variable to proxy-server rather than http_proxy is because I never could get http_proxy to work as is anyways then I did a simple: require 'rubygems' require 'watir-webdriver' ENV['TREX'] = "XX.XX.XX.XX:YY" browser = Watir::Browser.new(:chrome) browser.goto("http://mysite.com") Anyways, what is happening here is that it is forwarding me to the login page of the proxy rather than just forwarding the request. What am I missing here? I feel like I'm pretty close.

  • Regarding Visual C# MenuItem: Where does the NullReference come from?

    - by Thomas
    Hi All. I have a problem creating MenuItems for a TreeView dynamically: here is the (simplified)code i'm using. public class CTM : TreeNode, IComparable, IComparable<CTM> { public CTM(CTMProvider provider) { this.provider = provider; this.manager = provider.manager; this.IEEEAddress = provider.IEEEAddress; this.endpoint = provider.state._conn.RemoteEndPoint; this.Text = String.Format("CTM: {0} {0}", IEEEAddress, ((System.Net.IPEndPoint)endpoint).ToString()); try { MenuItem meni = System.EventHandler(this.provider.Disconnect)); this.ContextMenu.MenuItems.Add(meni); } catch { Trace.TraceError("Could not create menu item!"); } } } This code always triggers the catch clause with a NullReferenceException. Any Ideas?

  • GUI system architecture?

    - by topright
    I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

  • jQuery color plugin: onMouseOver animation causes flickering in FF3.5.5

    - by rt-uk
    I'm trying to change the background color of a div on mouseover and mouseout. Instant change to yellow on MouseOver, and slow fade on MouseOut. function hilightel(keydiv) { $('#'+keydiv).animate({ backgroundColor: '#ffffd3' },1); } function lolightel(keydiv) { $('#'+keydiv).animate({ backgroundColor: '#ffffff' },300); } < div onMouseOver=javascript:highlightel('item1'); onMouseOut=javascript:lolightel('item1'); id='item1'CONTENT< /div When the mouse moves over text within the div, though, it thinks I've moused-out and so flickers badly. Alternatives that don't work: - animateToClass doesn't support background-color so I'm using the 'color' plugin - I hear that switchClass doesn't work in Chrome - Can't use .hover because their will be dynamically named divs in the page so need a general function Thanks in advance...

  • How a servlet can get the absolute path to a file outside of the servlet?

    - by WolfmanDragon
    We have been using System.getProperties("user.dir") to get the location of a properties file. Now that it has been deployed on Tomcat(via servlet), the System call is giving the location as tomcat and not at the location at where the properties file exist. How can we call the the properties file dynamically? Given: Tomcat is not the only way the app will be deployed We have no control on where the app may be placed. Relative paths will not work as that Vista is being used and Vista breaks relative paths. This must work on all OS, including(but not limited to) Linux, XP and Vista. EDIT I implied this, but in case I was not clear enough, I have no way of knowing the path String.

  • Setting Grouping in UITableView under UINavigationController

    - by climbon
    In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.

    - by Freeman
    Fellows, I dont seem to be getting a solution. I have a a video gallery which I create by dynamically from a database.

Here is part of my javascript which is not working. $.ajax({ data:"search=vids&id="+ art, type: "POST", url: "doyit.php", success: function(msg){ $(".videogallery").html('<h3>Click to view videos of '+name+'</h3>'+msg); $('.video').bind('click',function(ev){ var vid=$(this).attr("href"); var img=$(this).find("img").attr("src") $(this).flash({swf: "mediaplayer.swf", flashvars: { file: vid, image: img } }) $(this).fancybox( { ajax:{ type:"POST"}, 'padding' : 0, 'autoScale' : false, 'transitionIn' : 'none', 'transitionOut' : 'none', 'title' : this.title, 'width' : 680, 'height' : 495 } ); $(this).unbind(ev) return false; }) } Any suggestions?

  • Preventing symbols from being stripped in IBM Visual Age C/C++ for AIX

    - by smountcastle
    I'm building a shared library which I dynamically load (using dlopen) into my AIX application using IBM's VisualAge C/C++ compiler. Unfortunately, it appears to be stripping out necessary symbols: rtld: 0712-002 fatal error: exiting. rtld: 0712-001 Symbol setVersion__Q2_3CIF17VersionReporterFRCQ2_3std12basic_stringXTcTQ2_3std11char_traitsXTc_TQ2_3std9allocatorXTc__ was referenced from module ./object/AIX-6.1-ppc/plugins/plugin.so(), but a runtime definition of the symbol was not found. Both the shared library and the application which loads the shared library compile/link against the static library which contains the VersionReporter mentioned in the error message. To link the shared library I'm using these options: -bM:SRE -bnoentry -bexpall To link the application, I'm using this option: -brtl Is there an option I can use to prevent this symbol from being stripped in the application? I've tried using -nogc as stated in the IBM docs, but that causes the shared library to be in an invalid format or the application to fail to link (depending on which one I use it with).

  • How to create curved Text on a Bitmap?

    - by TooFat
    I am currently dynamically creating a bitmap and using the graphics object from the string from the bitmap to Draw a string on it like so. System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, font, brush, new System.Drawing.Point(0, 0)); This returns a rectangle shaped bitmap with the string written straight across from left to right. I would like to also be able to draw the string in the shape of a rainbow. How can I do this?

  • Printable Version of Google Visualizations DataTable

    - by maleki
    I have a custom routing application that takes information for a route from google maps. It then creates a Google Visualizations DataTable to hold all the steps in the route. My current problem is that in order to reduce overflow for very large routes, I have enabled paging in the options of the DataTable. This leads to a not so printer friendly version because only the portion of the data that is shown in the table will be printed. The other portions of the table are loaded dynamically by the API when you click prev and next. Is there a not so hard way to get the DataTable to be printer friendly when it comes time without sacrificing the ability to have paging enabled?

  • Multiple Servers with identical services

    - by Jerry Bailey
    I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

  • UIButton to be resized

    - by Sathiya
    I am using a UIButton in my application. This button title is displayed dynamically as per the user choice. Now i have to resize the button width as per the title content. I am calculating the string length and assigning it to button's width. the button is resized as per title but the problem is as follows, 1. If at first the title with large content is shown and after that if a title with a small content is shown means the button is overwritten it doesn't remove the previously constructed value. 2. it looks as if one button is overlapped on the another.

  • How do I hide data/field in a List in J2ME

    - by pi
    Hi, I am working on a J2ME app which has dynamically generated Lists. Items on this list may be consequently selected, and the selection processed within the commandAction block. Is there a way to have the IDs of variables populating the List (from a remote database) included in the List item definition as in: this.append("A", null); this.append("B", null); or: String[] arrayOfValues = {"A", "B"}; new List("Menu", List.IMPLICIT, arrayOfValues, null); such that when an item is selected, perhaps A, I can also have its database ID for perhaps further processing. Is it possible to hide a field/data? Thanks.

  • How to specify a web service URL within a Drupal module's simpletest?

    - by Matt V.
    I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

  • Exclude some parameters with POST request on RestKit

    - by Mike Meyers
    I've just integrated RestKit with a Mac application for communicating with a web service. After much confusion, I have successfully got requests and responses working using it. The problem I am now finding is that when I want to make a POST request. I have created a RKRequestDescriptor with a mapping for a whole number of properties and all of the properties are being sent as parameters for the query. I want a way of dynamically changing the parameters that are sent, for example not sending some parameters where the property is nil. Is this possible as part of the built-in functionality of RestKit? And if so, how?

  • Adding a red5 app in a multiuser website

    - by Zakaria
    hi everybody, I have an mvc php website where users can publish their public information: http://www.example.com/foobar/profile. Beside this project, based on some red5 samples, I have an application (done with Flex) that sends audio: rtmp://server/sendAudio (very basic but works). I want to create for each subscribed on my website an admin part where can send an audio stream: http://admin.example.com/foobar. And, when someone goes on their public profile, they can listen to the streamed audio: http://www.example.com/foobar/profile). How can I use my red5/flash app dynamically with my php website so that my users can broadcast their proper canal? Do you have some experience to share ? Thank you, Regards.

  • dynamic silverlight content

    - by Jeremy
    I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

  • SSIS - Can I get the column schema for a flat file source from a database?

    - by Steve Clement
    We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

  • MySql products and categories tables using php and json

    - by Romina Mora
    I have just started learning all this coding language and the teacher is asking us to do the following. I know it may sound really easy for people who do this full time or have more time coding. The teacher is always telling us to GOOGLE everything and I have tried too many sites but I haven't found anything that helps me at all. I need to write two JSON documents (products and categories) using PHP that will dynamically read values from my MySQL database. When each document is called upon, it will return perfectly formatted JSON that will validate using http://jsonlint.com/ Honestly I don't know what to do. I don't understand PHP and now this JSON thing is making it more confusing.

  • Parsing a dynamic value with Lift-JSON

    - by Surya Suravarapu
    Let me explain this question with an example. If I have a JSON like the following: {"person1":{"name": "Name One", "address": {"street": "Some Street","city": "Some City"}}, "person2":{"name": "Name Two", "address": {"street": "Some Other Street","city": "Some Other City"}}} [There is no restriction on the number of persons, the input JSON can have many more persons] I could extract this JSON to Persons object by doing var persons = parse(res).extract[T] Here are the related case classes: case class Address(street: String, city: String) case class Person(name: String, address: Address, children: List[Child]) case class Persons(person1: Person, person2: Person) Question: The above scenario works perfectly fine. However the need is that the keys are dynamic in the key/value pairs. So in the example JSON provided, person1 and person2 could be anything, I need to read them dynamically. What's the best possible structure for Persons class to account for that dynamic nature.
