  • Java Thread Management and Application Flow

    - by user119179
    I have a Java application that downloads information (Entities) from our server. I use a Download thread to download the data. The flow of the download process is as follows: Log in - The user entity is downloaded Based on the User Entity, download a 'Community' entities List and Display in drop down Based on Community drop down selection, Download and show 'Org Tree' in a JTree Based on Node selection, download Category entities and display in drop down Based on Category selection, download Sub Category entities and display in drop down Based on Sub Category selection download a large data set and save it The download occurs in a thread so the GUI does not 'freeze'. It also allows me to update a Progress Bar. I need help with managing this process. The main problem is when I download entity data I have to find a way to wait for the thread to finish before attempting to get the entity and move to the next step in the app flow. So far I have used a modal dialog to control flow. I start the thread, pop up a modal and then dispose of the modal when the thread is finished. The modal/thread are Observer/Observable the thread does a set changed when it is finished and the dialog disposes. Displaying a modal effectively stops the flow of the application so it can wait for the download to finish. I also tried just moving all the work flow to Observers. All relevant GUI in the process are Observers. Each update method waits for the download to finish and then calls the next piece of GUI which does its own downloading. So far I found these two methods produce code that is hard to follow. I would like to 'centralize' this work flow so other developers are not pulling out their hair when they try to follow it. My Question is: Do you have any suggestions/examples where a work flow such as this can be managed in a way that produces code that is easy to follow? I know 'easy' is a relative term and I know my both my options already work but I would like to get some ideas from other coders while I still have time to change it. Thank you very much.

  • Convert a PDF to a Transparent PNG with GhostScript

    - by Jonathon Wolfe
    Hi all. I am attempting, unsuccessfully, to use Ghostscript to rasterize PDF files with a transparent background to PNG files with a transparent background. I've searched high and low for questions from others attempting the same thing and none of the posted solutions, which as far as I can tell come down to specifying -sDEVICE=pngalpha, have worked with my test files. At this point I would really appreciate any advice or tips a more experienced hand could provide. My test PDF is located here: http://www.kolossus.com/files/test.pdf It could be that the issue is with this file, but I doubt it. As far as I can tell, it has no specified background, and when I open the file with a transparency-aware app like Photoshop or Illustrator, sure enough it displays with a transparent background. However, when opened with an application like Adobe Reader the file is rendered with a white background. I believe that this has more to do with the application rendering the PDF than with the PDF itself -- apps like Adobe Reader assume you want to see what a printed document will look like and therefore always show a white canvas behind the artwork -- but I can't be sure. The gs command I'm using is: gs -dNOPAUSE -dBATCH -sDEVICE=pngalpha -r72 -sOutputFile=test.png test.pdf This produces a PNG that has transparent pixels outside of the bounding box of the artwork in the file, but all pixels that are inside the artwork's bounding box are rasterized against a white background. This is a problem for me, as my artwork has drop shadows and antialiased edges that need to be preserved in the final output, and can't just be postprocessed out with ImageMagick. A sample of my PNG output is at the same location as the pdf above, with .png at the end (stackoverflow won't let me include more than one url in my post). Interestingly, I see no effects from using the -dBackgroundColor flag, even if I set it to something non-white like -dBackgroundColor=16#ff0000. Perhaps my understanding of the syntax of this flag is wrong. Also interestingly, I see no effects from using the -dTextAlphaBits=4 -dGraphicsAlphaBits=4 flags to try to enable subpixel antialiasing. I would also appreciate any advice on how to enable subpixel antialiasing, especially on text. Finally, I'm using GPL Ghostscript 8.64 on Mac OS 10.5.7, and the rendering workflow I'm trying to get set up is to generate transparent PNG images from PDFs output by PrinceXML. I'm calling Ghostscript directly for the rasterization instead of using ImageMagick because ImageMagick delegates to Ghostscript for PDF rasterization and I should be able to control the rasterization better by calling GS directly. Thanks for your help. -Jon Wolfe

  • Why do .NET winforms scale improperly at large DPI settings?

    - by Alex
    My .NET application (VB.NET 3.5 if you really must know) forms do not properly format when rendered at high DPI settings. All of the fixes I've found so far simply explain the cause of the problem as "certain UI elements do not scale properly". I was wondering if anyone had a more meaningful explanation? Thanks!

  • How do you get the selected value of a spinner -- Android

    - by Matthew Hall
    Hi everyone, I'm trying to get the selected items string out of a spinner. So far I've got this: bundle.putString(ListDbAdapter.DB_PRI, v.getText().toString()); This doesn'y work and gives a casting exception (I thought you could cast a view to a widget that inherits it... obviously not!). So how do you get the selected value of a spinner

  • Solaris: Programmatic interface to ifconfig?

    - by David Citron
    I'm looking for a programmatic interface to the Solaris ifconfig(1M) command. Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris. Short of attempting to use the code at the link above, is there any way to determine ifconfig(1M)-type data (network interface presence, state, etc.) without forking the system command and parsing the output?

  • iPhone + OpenGL. How Do I Correctly Switch From Landscape to Portrait?

    - by dugla
    Because of the additional complexity of drawing via an EAGLView vs. a UIView I was wondering of someone has found a robust way to handle changing the device orientation from Landscape to Portrait. One approach is to tear down the framebuffer and rebuild from scratch which would require saving/retrieving scene state. The other would be far simpler: just rotate and resize the view. What is the best practice for this? Thanks, Doug

  • Can a custom WPF control implement the IsDefault property

    - by jpierson
    I have a custom button control that does not derive from Button. Is it possible for me to implement the equivalent of IsDefault so that the command associated with my control will be invoked. I was hoping that this was an attached property that I could add to any control but as far as I can tell it doesn't seem to be. Am I out of luck if my control does not derive from Button or is there at least a reasonable workaround?

  • Rails deployment from a windows machine

    - by Kenji Crosland
    I'm a rails novice and just finished my first rails app(as far as I can tell). Now I'm at the deployment stage and find myself utterly confused--especially because I'm deploying from a windows machine. I bought the pragmatic book on deployment and it seems a little out of date since they're recommending subversion instead of Git. What would be the easiest deployment method these days for someone doomed to use windows? Are there any good up-to-date tutorials on deployment from Windows?

  • Create a Session in Django

    - by Reznor
    So far the Documentation for Django has been too technical. How do I create a session and store variables in it or get variables from it? I'm new to the Django framework, hence why the Documentation is too technical. Sessions are my 'last step'.

  • XML Schema (XSD) to Rails ActiveRecord Mapping?

    - by Incomethax
    I'm looking for a way to convert an XML Schema definition file into an ActiveRecord modeled database. Does anyone know of a tool that happens to do this? So far the best way I've found is to first load the XSD into an RDBMS like postgres or mysql and then have rails connect to do a rake db:schema:dump. This however, only leaves me with a database without rails Models. What would be the best way to import/load this xsd based database into rails?

  • Regular expressions and the question mark

    - by James P.
    I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions?

  • Looking for exercises to learn SQL, using the Northwind database

    - by MedicineMan
    I am trying to become more familiar with SQL by writing queries against the Northwind database. I am looking for some exercises that would help me to learn SQL and features of SQL Server. It is important that the exercises have solutions, and in complicated cases, it would be great if there was an explanation for the query. Thanks for the answers so far but I still have not found what I am looking for: Is there any free resource, available online, without registration, that I can find a list of these exercises?

  • ruby socket dgram example

    - by Bub Bradlee
    I'm trying to use unix sockets and SOCK_DGRAM in ruby, but am having a really hard time figuring out how to do it. So far, I've been trying things like this: sock_path = 'test.socket' s1 = Socket.new(Socket::AF_UNIX, Socket::SOCK_DGRAM, 0) s1.bind(Socket.pack_sockaddr_un(sock_path)) s2 = Socket.new(Socket::AF_UNIX, Socket::SOCK_DGRAM, 0) s2.bind(Socket.pack_sockaddr_un(sock_path)) s1.send("HELLO") s2.recv(5) # should equal "HELLO" Does anybody have experience with this?

  • Easiest way to implement RSS reader on Google Android?

    - by user291888
    Hi guys, This is my first time on stack overflow, so I apologize if this question has been asked before, but is there an easy way to implement an RSS reader on the Google Android (API 1.5)? I'm searched far and wide with the code sources I know of, and I've only found one implementation which takes 6 different classes and doesn't seem to compile on the current Android SDK's. If I end up having to write my own, I'll be sure to post it here later on. Thanks a lot.

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.

  • Anybody got a C# function that maps the SQL datatype of a column to its CLR equivalent?

    - by Chris McCall
    I'm sitting down to write a massive switch() statement to turn SQL datatypes into CLR datatypes in order to generate classes from MSSQL stored procedures. I'm using this chart as a reference. Before I get too far into what will probably take all day and be a huge pain to fully test, I'd like to call out to the SO community to see if anyone else has already written or found something in C# to accomplish this seemingly common and assuredly tedious task.

  • JSF vs Stripes, which is best?

    - by Davoink
    Which is best, or in other words, whish is easiest to use? Stripes or JSF. Although I haven't used both in anger I need to gauge what is the best option to work with for both starting new projects and converting existing Struts projects. I have a fear that JSF won't render as nicely as I want but what are others experiences? Seems Stripes is far more straight forward, would I be correct in this assumption? Cheers.

  • Website Development moving to Image Hosting

    - by Drew
    We are moving over to using Akamai for all of our large static content so far just flash but are planning to include images, css, and js files in that list. I am curious what methods others employ to switch all of their local/relative paths to using an external hosting company. Also, how they continue to develop their site so that developers can make changes in development without it having to be pushed to their external hosting servers.

  • Advice on logic circuits and serial communications

    - by Spencer Ruport
    As far as I understand the serial port so far, transferring data is done over pin 3. As shown here: There are two things that make me uncomfortable about this. The first is that it seems to imply that the two connected devices agree on a signal speed and the second is that even if they are configured to run at the same speed you run into possible synchronization issues... right? Such things can be handled I suppose but it seems like there must be a simpler method. What seems like a better approach to me would be to have one of the serial port pins send a pulse that indicates that the next bit is ready to be stored. So if we're hooking these pins up to a shift register we basically have: (some pulse pin)-clk, tx-d Is this a common practice? Is there some reason not to do this? EDIT Mike shouldn't have deleted his answer. This I2C (2 pin serial) approach seems fairly close to what I did. The serial port doesn't have a clock you're right nobugz but that's basically what I've done. See here: private void SendBytes(byte[] data) { int baudRate = 0; int byteToSend = 0; int bitToSend = 0; byte bitmask = 0; byte[] trigger = new byte[1]; trigger[0] = 0; SerialPort p; try { p = new SerialPort(cmbPorts.Text); } catch { return; } if (!int.TryParse(txtBaudRate.Text, out baudRate)) return; if (baudRate < 100) return; p.BaudRate = baudRate; for (int index = 0; index < data.Length * 8; index++) { byteToSend = (int)(index / 8); bitToSend = index - (byteToSend * 8); bitmask = (byte)System.Math.Pow(2, bitToSend); p.Open(); p.Parity = Parity.Space; p.RtsEnable = (byte)(data[byteToSend] & bitmask) > 0; s = p.BaseStream; s.WriteByte(trigger[0]); p.Close(); } } Before anyone tells me how ugly this is or how I'm destroying my transfer speeds my quick answer is I don't care about that. My point is this seems much much simpler than the method you described in your answer nobugz. And it wouldn't be as ugly if the .Net SerialPort class gave me more control over the pin signals. Are there other serial port APIs that do?
