  • Zelda-style top-down RPG. How to store tile and collision data?

    - by Delerat
    I'm looking to build a Zelda: LTTP style top-down RPG. I've read a lot on the subject and am currently going back and forth on a few solutions. I'm using C#, MonoGame, and Tiled. For my tile maps, these are the choices I can see in front of me: Store each tile as its own array. Each one having 3-4 layers, texture/animation, depth, flags, and maybe collision(depending on how I do it). I've read warning about memory issues going this route, and my biggest map will probably be 160x120 tiles. My average map however will be about 40x30. The number of tiles might cut in half if I decide to double my tile size, which is currently 16x16. This is the most appealing approach for me, as I feel like I would know how to save maps, make changes, and separate it into chunks for collision checks. Store the static parts of my tile map in multiple arrays acting as the different layers. Then I would just use entities for anything that wasn't static. All of the other tile data such as collisions, depth, etc., would be stored in their own layers as well I guess? This way just seems messy to me though. Regardless of which one I choose, I'm also unsure how to plan all of that other tile data. I could write a bunch of code that would know which integer represents what tile and it's data, but if I changed a tileset in Tiled and exported it again, all of those integers could potentially change and I'd have to adjust a whole bunch of code. My other issue is about how I could do collision. I want to at least support angled collision that slides you around the corners of objects like LTTP does, if not more oddball shapes as well. So do I: Store collision as a flag for binary collision. Could I get this to support angles? Would it be fine to store collision as an integer and have each number represent a certain angle of collision? Store a list of rectangles or other shapes and do collision that way? Sorry for the large two-part(three-part?) question. I felt like these needed to be asked together as I believe each choice influences the other.

  • UK Data Breaches Up by 10 fold in 10 years.

    - by TATWORTH
    At http://www.v3.co.uk/v3-uk/news/2201863/uk-data-breaches-rocket-by-1-000-percent-over-past-five-years there is an interesting report on the increase in data breaches reported in the UK.A lot of this increase may simply a change in legislation that has made reporting a statutory obligation.Some questions to ask yourself:Are server logs checked for untoward activity?Do you have a reporting policy if something is amiss?Did you design security in for the start of your application design?Do you log for example failed logons?Do you run tools to check for code integrity?Is my defense, a strategy of defense in depth?Do you realise that 60% of hack attacks are internal?Whilst SQL Injection is a problem that affects practically all application code platforms, within Microsoft Applications do you run FXCOP? Do you run any of the other free tools for checking?

  • How can I fix a very broken Ubuntu installation without losing data?

    - by jredkai
    Okay guys, I was installing a program (I do not remember the name). When I did sudo apt-get update I was given missing dependencies. It told me to sudo apt-get install -f which deleted just about every dependency needed for Ubuntu, now I cannot log in or anything, now in GRUB it actually says Debian instead of Ubuntu. I have tons of important data in that partition. Can I some how use the live cd to fix this problem??? I mean like re-install without losing data. Any help is greatly appreciated!!!

  • Is a blob more efficient than a varchar for data that can be ANY size?

    - by BillyNair
    When setting up a database I want to use the most efficient data type for potentially fairly long data. Currently my project is to store song titles and thoughts pertaining to that song. Some titles might be 5 characters or longer than 100 characters and the thoughts could run pretty long. Is it more efficient to use a varchar set to 8000 or to use a blob? Is using a blob the same as a varchar, in that there is a set size it is allocated regardless of what it holds? or is it just a pointer and it doesn't really use much space on the table? Is there a certain set size of a blob in KB or is it expandable?

  • Does the direction of storage make us bad data citizens?

    - by simonsabin
      My career started at a company where we hardly had email, the network was a 10base2 affair with cables running all around the office. You used floppy disks and the thought of a GB of data was absurd. You had to look after every byte and only keep what you really needed. Whilst the cost of the spinning disks gradually falls the cost and size of flash storage continues to plummet. The new Crucial SSD is £380 for 1TB I can now keep 128GB of data on a SD card the size of my finger. It only costs...(read more)

  • How to visualize real time data on Android? [closed]

    - by matarsak
    I want to build and android app that visualizes real time data (2D animation). I set up a UDP channel that get the data, now I want to visualize it. I know that I can use OpenGL ES, but after a few weeks, I dont think that I'm able to learn that. What about Android Processing? Could it be used for an extensive visualization task like this? or is it limited in some way? I've heard it's not hard learn. Any other options?

  • Android WebView not loading a JavaScript file, but Android Browser loads it fine.

    - by Justin
    I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions. More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent. Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB; import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.app.ProgressDialog; import android.content.DialogInterface; import android.graphics.Bitmap; import android.os.Bundle; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; import android.view.Window; import android.webkit.WebChromeClient; import android.webkit.WebView; import android.webkit.WebSettings; import android.webkit.WebViewClient; import android.widget.Toast; public class myKMB extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /** Performs base set up */ /** Create a Activity of this Activity, IE myProcess */ myProcess = this; /*** Create global objects and web browsing objects */ HideDialogOnce = true; webview = new WebView(this) { }; webChromeClient = new WebChromeClient() { public void onProgressChanged(WebView view, int progress) { // Activities and WebViews measure progress with different scales. // The progress meter will automatically disappear when we reach 100% myProcess.setProgress((progress * 100)); //CreateMessage("Progress is : " + progress); } }; webViewClient = new WebViewClient() { public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Toast.makeText(myProcess, MessageBegText + description + MessageEndText, Toast.LENGTH_SHORT).show(); } public void onPageFinished (WebView view, String url) { /** Hide dialog */ try { // loadingDialog.dismiss(); } finally { } //myProcess.setProgress(1000); /** Fon't show the dialog while I'm performing fixes */ //HideDialogOnce = true; view.loadUrl("javascript:document.getElementById('JTRANS011').style.visibility='visible';"); } public void onPageStarted(WebView view, String url, Bitmap favicon) { if (HideDialogOnce == false) { //loadingDialog = ProgressDialog.show(myProcess, "", // "One moment, the page is laoding...", true); } else { //HideDialogOnce = true; } } }; getWindow().requestFeature(Window.FEATURE_PROGRESS); webview.setWebChromeClient(webChromeClient); webview.setWebViewClient(webViewClient); setContentView(webview); /** Load the Keynote Browser Settings */ LoadSettings(); webview.loadUrl(LandingPage); } /** Get Menu */ @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu, menu); return true; } /** an item gets pushed */ @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { // We have only one menu option case R.id.quit: System.exit(0); break; case R.id.back: webview.goBack(); case R.id.refresh: webview.reload(); case R.id.info: //IncludeJavascript(""); } return true; } /** Begin Globals */ public WebView webview; public WebChromeClient webChromeClient; public WebViewClient webViewClient; public ProgressDialog loadingDialog; public Boolean HideDialogOnce; public Activity myProcess; public String OverideUserAgent_IE = "Mozilla/5.0 (Windows; MSIE 6.0; Android 1.6; en-US) AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4 Safari/523.12.2 myKMB/1.0"; public String LandingPage = "http://kscserver.com/main-leap-slim.html"; public String MessageBegText = "Problem making a connection, Details: "; public String MessageEndText = " For Support Call: (xxx) xxx - xxxx."; public void LoadSettings() { webview.getSettings().setUserAgentString(OverideUserAgent_IE); webview.getSettings().setJavaScriptEnabled(true); webview.getSettings().setBuiltInZoomControls(true); webview.getSettings().setSupportZoom(true); } /** Creates a message alert dialog */ public void CreateMessage(String message) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(message) .setCancelable(true) .setNegativeButton("Close", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); } } My Application is running in the background, and as you can see no Firebug in the lower right hand corner. However the browser (the emulator on top) has the same page but shows the firebug. What am I doing wrong? I'm assuming its either not enough memory allocated to the application, process power allocation, or a physical memory thing. I can't tell, all I know is the results are strange. I get the same thing form my android device, the application shows no firebug but the browser shows the firebug.

  • need prefuse graph edges like arrows

    - by merve
    Hello, I did my homework and searched both google for a sample and a topic that is answered before on stackoverflow. But nothing has been found. My problem is ordinary edges who does not have a view like arrows. Here is what i do to hope there is forward arrows from target to destination: LabelRenderer nameLabel = new LabelRenderer("name"); nameLabel.setRoundedCorner(8, 8); DefaultRendererFactory rendererFactory = new DefaultRendererFactory(nameLabel); EdgeRenderer edgeRenderer; edgeRenderer = new EdgeRenderer(prefuse.Constants.EDGE_TYPE_LINE, prefuse.Constants.EDGE_ARROW_FORWARD); rendererFactory.setDefaultEdgeRenderer(edgeRenderer); vis.setRendererFactory(rendererFactory); Here is what i see about colour of edges, hoping these must not be transparent: int[] palette = new int[]{ColorLib.rgb(255, 180, 180), ColorLib.rgb(190, 190, 255)}; DataColorAction fill = new DataColorAction("socialnet.nodes", "gender", Constants.NOMINAL, VisualItem.FILLCOLOR, palette); ColorAction text = new ColorAction("socialnet.nodes", VisualItem.TEXTCOLOR, ColorLib.gray(0)); ColorAction edges = new ColorAction("socialnet.edges", VisualItem.STROKECOLOR, ColorLib.gray(200)); ColorAction arrow = new ColorAction("socialnet.edges", VisualItem.FILLCOLOR, ColorLib.gray(200)); ActionList colour = new ActionList(); colour.add(fill); colour.add(text); colour.add(edges); colour.add(arrow); vis.putAction("colour", colour); Thus, i wonder where am i wrong? Why my edges do not seem like arrows? Thanks for any idea.

  • Why does this ActionFilterAttribute not import data to the ViewModel?

    I have the following attribute public class ImportStatusAttribute : ActionFilterAttribute { public override void OnActionExecuted(ActionExecutedContext filterContext) { var model = (IHasStatus)filterContext.Controller.ViewData.Model; model.Status = (StatusMessageViewModel)filterContext.Controller.TempData["status"]; filterContext.Controller.ViewData.Model = model; } } which I test with the following test method (the first of several I'll write when this one passes...) [TestMethod] public void OnActionExecuted_ImportsStatusFromTempDataToModel() { // Arrange Expect(new { Status = new StatusMessageViewModel() { Subject = "The test", Predicate = "has been tested" }, Key = "status" }); var filterContext = new Mock<ActionExecutedContext>(); var model = new Mock<IHasStatus>(); var tempData = new TempDataDictionary(); var viewData = new ViewDataDictionary(model.Object); var controller = new FakeController() { ViewData = viewData, TempData = tempData }; tempData.Add(expected.Key, expected.Status); filterContext.Setup(c => c.Controller).Returns(controller); var attribute = new ImportStatusAttribute(); // Act attribute.OnActionExecuted(filterContext.Object); // Assert Assert.IsNotNull(model.Object.Status, "The status was not exported"); Assert.AreEqual(model.Object.Status.ToString(), ((StatusMessageViewModel)expected.Status).ToString(), "The status was not the expected"); } (Expect() is a method that saves some expectations in the expected object...) When I run the test, it fails on the first assertion, and I can't get my head around why. Debugging, I can see that model is populated correctly, and that (StatusMessageViewModel)filterContext.Controller.TempData["status"] has the correct data. But after model.Status = (StatusMessageViewModel)filterContext.Controller.TempData["status"]; model.Status is still null in my watch window. Why can't I do this?

  • How to display different value with ComboBoxTableCell?

    - by Philippe Jean
    I try to use ComboxBoxTableCell without success. The content of the cell display the right value for the attribute of an object. But when the combobox is displayed, all items are displayed with the toString object method and not the attribute. I tryed to override updateItem of ComboBoxTableCell or to provide a StringConverter but nothing works. Do you have some ideas to custom comboxbox list display in a table cell ? I put a short example below to see quickly the problem. Execute the app and click in the cell, you will see the combobox with toString value of the object. package javafx2; import javafx.application.Application; import javafx.beans.property.adapter.JavaBeanObjectPropertyBuilder; import javafx.beans.value.ObservableValue; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.scene.Scene; import javafx.scene.control.TableCell; import javafx.scene.control.TableColumn; import javafx.scene.control.TableColumn.CellDataFeatures; import javafx.scene.control.TableView; import javafx.scene.control.cell.ComboBoxTableCell; import javafx.stage.Stage; import javafx.util.Callback; import javafx.util.StringConverter; public class ComboBoxTableCellTest extends Application { public class Product { private String name; public Product(String name) { this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } } public class Command { private Integer quantite; private Product product; public Command(Product product, Integer quantite) { this.product = product; this.quantite = quantite; } public Integer getQuantite() { return quantite; } public void setQuantite(Integer quantite) { this.quantite = quantite; } public Product getProduct() { return product; } public void setProduct(Product product) { this.product = product; } } public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) throws Exception { Product p1 = new Product("Product 1"); Product p2 = new Product("Product 2"); final ObservableList<Product> products = FXCollections.observableArrayList(p1, p2); ObservableList<Command> commands = FXCollections.observableArrayList(new Command(p1, 20)); TableView<Command> tv = new TableView<Command>(); tv.setItems(commands); TableColumn<Command, Product> tc = new TableColumn<Command, Product>("Product"); tc.setMinWidth(140); tc.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Command,Product>, ObservableValue<Product>>() { @Override public ObservableValue<Product> call(CellDataFeatures<Command, Product> cdf) { try { JavaBeanObjectPropertyBuilder<Product> jbdpb = JavaBeanObjectPropertyBuilder.create(); jbdpb.bean(cdf.getValue()); jbdpb.name("product"); return (ObservableValue) jbdpb.build(); } catch (NoSuchMethodException e) { System.err.println(e.getMessage()); } return null; } }); final StringConverter<Product> converter = new StringConverter<ComboBoxTableCellTest.Product>() { @Override public String toString(Product p) { return p.getName(); } @Override public Product fromString(String s) { // TODO Auto-generated method stub return null; } }; tc.setCellFactory(new Callback<TableColumn<Command,Product>, TableCell<Command,Product>>() { @Override public TableCell<Command, Product> call(TableColumn<Command, Product> tc) { return new ComboBoxTableCell<Command, Product>(converter, products) { @Override public void updateItem(Product product, boolean empty) { super.updateItem(product, empty); if (product != null) { setText(product.getName()); } } }; } }); tv.getColumns().add(tc); tv.setEditable(true); Scene scene = new Scene(tv, 140, 200); stage.setScene(scene); stage.show(); } }

  • How to export SSIS to Microsoft Excel without additional software?

    - by Dr. Zim
    This question is long winded because I have been updating the question over a very long time trying to get SSIS to properly export Excel data. I managed to solve this issue, although not correctly. Aside from someone providing a correct answer, the solution listed in this question is not terrible. The only answer I found was to create a single row named range wide enough for my columns. In the named range put sample data and hide it. SSIS appends the data and reads metadata from the single row (that is close enough for it to drop stuff in it). The data takes the format of the hidden single row. This allows headers, etc. WOW what a pain in the butt. It will take over 450 days of exports to recover the time lost. However, I still love SSIS and will continue to use it because it is still way better than Filemaker LOL. My next attempt will be doing the same thing in the report server. Original question notes: If you are in Sql Server Integrations Services designer and want to export data to an Excel file starting on something other than the first line, lets say the forth line, how do you specify this? I tried going in to the Excel Destination of the Data Flow, changed the AccessMode to OpenRowSet from Variable, then set the variable to "YPlatters$A4:I20000" This fails saying it cannot find the sheet. The sheet is called YPlatters. I thought you could specify (Sheet$)(Starting Cell):(Ending Cell)? Update Apparently in Excel you can select a set of cells and name them with the name box. This allows you to select the name instead of the sheet without the $ dollar sign. Oddly enough, whatever the range you specify, it appends the data to the next row after the range. Oddly, as you add data, it increases the named selection's row count. Another odd thing is the data takes the format of the last line of the range specified. My header rows are bold. If I specify a range that ends with the header row, the data appends to the row below, and makes all the entries bold. if you specify one row lower, it puts a blank line between the header row and the data, but the data is not bold. Another update No matter what I try, SSIS samples the "first row" of the file and sets the metadata according to what it finds. However, if you have sample data that has a value of zero but is formatted as the first row, it treats that column as text and inserts numeric values with a single quote in front ('123.34). I also tried headers that do not reflect the data types of the columns. I tried changing the metadata of the Excel destination, but it always changes it back when I run the project, then fails saying it will truncate data. If I tell it to ignore errors, it imports everything except that column. Several days of several hours a piece later... Another update I tried every combination. A mostly working example is to create the named range starting with the column headers. Format your column headers as you want the data to look as the data takes on this format. In my example, these exist from A4 to E4, which is my defined range. SSIS appends to the row after the defined range, so defining A4 to E68 appends the rows starting at A69. You define the Connection as having the first row contains the field names. It takes on the metadata of the header row, oddly, not the second row, and it guesses at the data type, not the formatted data type of the column, i.e., headers are text, so all my metadata is text. If your headers are bold, so is all of your data. I even tried making a sample data row without success... I don't think anyone actually uses Excel with the default MS SSIS export. If you could define the "insert range" (A5 to E5) with no header row and format those columns (currency, not bold, etc.) without it skipping a row in Excel, this would be very helpful. From what I gather, noone uses SSIS to export Excel without a third party connection manager. Any ideas on how to set this up properly so that data is formatted correctly, i.e., the metadata read from Excel is proper to the real data, and formatting inherits from the first row of data, not the headers in Excel? One last update (July 17, 2009) I got this to work very well. One thing I added to Excel was the IMEX=1 in the Excel connection string: "Excel 8.0;HDR=Yes;IMEX=1". This forces Excel (I think) to look at all rows to see what kind of data is in it. Generally, this does not drop information, say for instance if you have a zip code then about 9 rows down you have a zip+4, Excel without this blanks that field entirely without error. With IMEX=1, it recognizes that Zip is actually a character field instead of numeric. And of course, one more update (August 27, 2009) The IMEX=1 will succeed importing data with missing contents in the first 8 rows, but it will fail exporting data where no data exists. So, have it on your import connection string, but not your export Excel connection string. I have to say, after so much fiddling, it works pretty well.

  • SSRS 2005: How do I make available varbinary data for download in a report?

    - by Angelo
    Hi, SSRS newbie question here... I have a table where one column is varbinary(max) data. I would like to make a report that makes this data available for download as a hyperlink so the user can just click on the item and get a file download dialog for the binary data. In this particular case, the binary data happens to be the content of old pdf files, but that shouldn't matter. I tried searching around but I can't find any pointers on how to do this. It seems to me that it should be possible. There are ways to display images in a report using varbinary data, so it makes sense that one should be able to make arbitrary binary data downloadable on a report, right?

  • Is there a format or service for resume/CV data?

    - by Ben Dauphinee
    I have noticed through the process of signing up for various freelance and job seeking or professional network sites that they all want your resume/CV data. And I am really getting tired of copy/pasting this data, especially since I have a website. Is there a standard format or service somewhere that I do not know about for this data? If not, does anyone want to help me build something like this out? I'm thinking a service similar to OpenID that allows you to maintain a central resume to have your data pulled from. No more filling in the same data over and over, and having to maintain the copies on any of the plethora of websites that have that data. Takers?

The files will be created at the first start of the program with this call: File f; f = new File(Toplist.toplistPath+"/top_1.dat"); if(!f.exists()){ Toplist.makeToplist(); } Here is the toplist class: package main; import java.awt.Color; import java.io.BufferedReader; import java.io.File; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.prefs.Preferences; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JTextArea; public class Toplist { static String toplistPath = "./Torpedo/local/toplist"; //I know it won't work this easily, it's only to get you the idea public static JFrame toplistWindow = new JFrame("Torpedó - [TOPLISTA]"); public static JTextArea toplist = new JTextArea(""); static StringBuffer toplistData = new StringBuffer(3000); public Toplist() { toplistWindow.setSize(500, 400); toplistWindow.setLocationRelativeTo(null); toplistWindow.setResizable(false); getToplist(); toplist.setSize(400, 400); toplist.setLocation(0, 100); toplist.setColumns(5); toplist.setText(toplistData.toString()); toplist.setEditable(false); toplist.setBackground(Color.WHITE); toplistWindow.setLayout(null); toplistWindow.setVisible(true); } public Toplist(Player winner) { //this is to be done yet, this will set the toplist at first and then display it toplistWindow.setLayout(null); toplistWindow.setVisible(true); } /** * Creates a new toplist */ public static void makeToplist(){ new File(toplistPath).mkdir(); for(int i = 1; i <= 10; i++){ File f = new File(toplistPath+"/top_"+i+".dat"); try { f.createNewFile(); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista létrehozása", "Error", JOptionPane.ERROR_MESSAGE); } } } /** * If the score is a top score it inserts it into the list * * @param score - the score to be checked */ public static void setToplist(int score, Player winner){ BufferedReader input = null; PrintWriter output = null; int topscore; for(int i = 1; i <= 10; i++){ try { input = new BufferedReader(new FileReader(toplistPath+"/top_"+i+",dat")); String s; topscore = Integer.parseInt(input.readLine()); if(score > topscore){ for(int j = 9; j >= i; j--){ input = new BufferedReader(new FileReader(toplistPath+"/top_"+j+".dat")); output = new PrintWriter(new FileWriter(toplistPath+"/top_"+(j+1)+".dat")); while ((s = input.readLine()) != null) { output.println(s); } } output = new PrintWriter(new FileWriter(toplistPath+"/top_"+i+".dat")); output.println(score); output.println(winner.name); if(winner.isLocal){ output.println(Torpedo.session.remote.name); }else{ output.println(Torpedo.session.remote.name); } output.println(Torpedo.session.mapName); output.println(DateUtils.now()); break; } } catch (FileNotFoundException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } finally { if (input != null) { try { input.close(); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista frissítése", "Error", JOptionPane.ERROR_MESSAGE); } } if (output != null) { output.close(); } } } } /** * This loads the toplist into the buffer */ public static void getToplist(){ BufferedReader input = null; toplistData = null; String s; for(int i = 1; i <= 10; i++){ try { input = new BufferedReader(new FileReader(toplistPath+"/top_"+i+".dat")); while((s = input.readLine()) != null){ toplistData.append(s); toplistData.append('\t'); } toplistData.append('\n'); } catch (FileNotFoundException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista betöltése", "Error", JOptionPane.ERROR_MESSAGE); } catch (IOException e) { JOptionPane.showMessageDialog(new JFrame(), "Fájl hiba: toplista betöltése", "Error", JOptionPane.ERROR_MESSAGE); } } } /** * * @author http://www.rgagnon.com/javadetails/java-0106.html * */ public static class DateUtils { public static final String DATE_FORMAT_NOW = "yyyy-MM-dd HH:mm:ss"; public static String now() { Calendar cal = Calendar.getInstance(); SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_NOW); return sdf.format(cal.getTime()); } } } The problem is, that it can't access any of the files. I've tried adding them to the classpath and at least six different variations of file/path handling I found online but nothing worked. Could anyone tell me what do I do wrong? Thank you.

  • Entity framework (1): implement 1 foreign key to multiple tables

    - by Michel
    Hi, i've modeled this: i have an import table, and an import steps table import 1 .. N importsteps Now i have a table importparams, which hold key/value pairs to register all kind of info about the import or the importsteps. So i have modeled a FK in SqlServer which points to the PK of the import table and to the PK of the importsteps table (the ID's for both the import as the importsteps table are guids, so i can query the importparams with either the id from import or from importsteps and get the right importparams). Makes sense a bit? But how can i model this in the EF? I can see it's a bit hard for the EF to model this, because one realtion can point to multiple classes, but is there a way? The workaround normally is just to get all importparams where FK is the ID, but as you know the FK is not available in the EF version 1. I hope you can help me out, michel

  • How to think in data stores instead of databases?

    - by Jim
    As an example, Google App Engine uses data stores, not a database, to store data. Does anybody have any tips for using data stores instead of databases? It seems I've trained my mind to think 100% in object relationships that map directly to table structures, and now it's hard to see anything differently. I can understand some of the benefits of data stores (e.g. performance and the ability to distribute data), but some good database functionality is sacrificed (e.g. joins). Does anybody who has worked with data stores like BigTable have any good advice to working with them?

  • How can I structure and recode messy categorical data in R?

    - by briandk
    I'm struggling with how to best structure categorical data that's messy, and comes from a dataset I'll need to clean. The Coding Scheme I'm analyzing data from a university science course exam. We're looking at patterns in student responses, and we developed a coding scheme to represent the kinds of things students are doing in their answers. A subset of the coding scheme is shown below. Note that within each major code (1, 2, 3) are nested non-unique sub-codes (a, b, ...). What the Raw Data Looks Like I've created an anonymized, raw subset of my actual data which you can view here. Part of my problem is that those who coded the data noticed that some students displayed multiple patterns. The coders' solution was to create enough columns (reason1, reason2, ...) to hold students with multiple patterns. That becomes important because the order (reason1, reason2) is arbitrary--two students (like student 41 and student 42 in my dataset) who correctly applied "dependency" should both register in an analysis, regardless of whether 3a appears in the reason column or the reason2 column. How Can I Best Structure Student Data? Part of my problem is that in the raw data, not all students display the same patterns, or the same number of them, in the same order. Some students may do just one thing, others may do several. So, an abstracted representation of example students might look like this: Note in the example above that student002 and student003 both are coded as "1b", although I've deliberately shown the order as different to reflect the reality of my data. My (Practical) Questions Should I concatenate reason1, reason2, ... into one column? How can I (re)code the reasons in R to reflect the multiplicity for some students? Thanks I realize this question is as much about good data conceptualization as it is about specific features of R, but I thought it would be appropriate to ask it here. If you feel it's inappropriate for me to ask the question, please let me know in the comments, and stackoverflow will automatically flood my inbox with sadface emoticons. If I haven't been specific enough, please let me know and I'll do my best to be clearer.

  • Is there a way to only backup a SQL 2005 database structure fully, but only the data in a certain se

    - by TheSoftwareJedi
    I have several schemas in my database, and the largest one ("large" meaning disk space consumed) is my "web" schema which is a denormalized copy of data in the operational schemas. This denormalized data is able to be reconstructed at anytime, and is merely there for extremely fast read purposes. Since the data is redundant, and VERY large - I'd like to exclude it from being backed up. I already have stored procedures that can regenerate all of the data in that schema in a couple of hours - for use in the event of a failure. I assume I can split the tables in this schema out to another data file or such (ideally even on another drive for faster reads), but is there a way to never have that data file backup, yet still in the event of a failure its structure could be restored (and other DDL stuff like procs, views, etc)? Somewhat related, can I also have these tables not do transaction logging, if I go to "Full" backup mode for the rest of the database?
