  • Creating Transparent Game Menu Items using AndEngine

    - by Chaitanya Chandurkar
    I'm trying to create a Game Menu which contains some Menu Items like New Game Multiplayer Options Exit I want to make this Menu Items Transparent. Only Text in White color should be visible. So i guess i do not need any background image for Menu Items. I have seen examples of SpriteButton like given below. ButtonSprite playButton = new ButtonSprite(0, 0, btnNormalTextureRegion, btnPushedTextureRegion, this.getVertexBufferObjectManager(), new OnClickListener() { @Override public boolean onAreaTouched(TouchEvent pSceneTouchEvent, float pTouchAreaLocalX, float pTouchAreaLocalY) { // Do Stuff here } } The thing which i don't understand is how can i initialize btnNormalTextureRegion? I use the code give below to initialize ITexture and ITextureRegion for objects. mBackgruondTexture = new BitmapTexture(activity.getTextureManager(), new IInputStreamOpener() { public InputStream open() throws IOException { return activity.getAssets().open("gfx/backgrounds/greenbg.jpg"); } }); mBackgruondTextureRegion = TextureRegionFactory.extractFromTexture(mBackgruondTexture); This code openes up an Image from assest. As i do not want to use any image for Menu Item How can i initialize btnNormalTextureRegion for SpriteButton. OR Is there any alternative to create Game Menu?

  • Transparent JPanel, Canvas background in JFrame

    - by Andy Tyurin
    I wanna make canvas background and add some elements on top of it. For this goal I made JPanel as transparent container with setOpaque(false) and added it as first of JFrame container, then I added canvas with black background (in future I wanna set animation) to JFrame as second element. But I can't undestand why i see grey background, not a black. Any suggestions? public class Game extends JFrame { public Container container; //Game container with components public Canvas backgroundLayer; //Background layer of a game public JPanel elementsLayer; //elements panel (top of backgroundLayer), holds different elements private Dimension startGameDimension = new Dimension(800,600); //start game dimension public Game() { //init main window super("Astra LaserForces"); setSize(startGameDimension); setBackground(Color.CYAN); container=getContentPane(); container.setLayout(null); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //init jpanel elements layer elementsLayer=new JPanel(); elementsLayer.setSize(startGameDimension); elementsLayer.setBackground(Color.BLUE); elementsLayer.setOpaque(false); container.add(elementsLayer); //init canvas background layer backgroundLayer = new Canvas(); backgroundLayer.setSize(startGameDimension); backgroundLayer.setBackground(Color.BLACK); //set default black color container.add(backgroundLayer); } //start game public void start() { setVisible(true); } //create new instance of game and start it public static void main(String[] args) { new Game().start(); } }

  • XNA 4: RenderTarget2D textures getting transparent on fullscreen

    - by Shashwat
    I'm generating a Texture2D object using RenderTarget2D as in the following code public static Texture2D GetTextTexture(string text, Vector2 position, SpriteFont font, Color foreColor, Color backColor, Texture2D background=null) { int width = (int)font.MeasureString(text).X; int height = (int)font.MeasureString(text).Y; GraphicsDevice device = Settings.game.GraphicsDevice; SpriteBatch spriteBatch = Settings.game.spriteBatch; RenderTarget2D renderTarget = new RenderTarget2D(device, width, height, false, SurfaceFormat.Color, DepthFormat.Depth24Stencil8, device.PresentationParameters.MultiSampleCount, RenderTargetUsage.DiscardContents); device.SetRenderTarget(renderTarget); device.Clear(backColor); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque); if (background != null) spriteBatch.Draw(background, new Rectangle(0, 0, 70, 70), Color.White); spriteBatch.End(); spriteBatch.Begin(); spriteBatch.DrawString(font, text, position, foreColor, 0, new Vector2(0), 0.8f, SpriteEffects.None, 0); spriteBatch.End(); device.SetRenderTarget(null); ResetGraphicsDeviceSettings(); return (Texture2D)renderTarget; } It's working all fine. But when I ToggleFullScreen() (and vice-versa), the previous textures are getting transparent. However, the new textures after that are being generated correctly. What can be the reason for this?

  • software to monitor internet usage on an XP PC? (browser + non-browser)

    - by user39316
    Hi Is there any (ideally open source) software for Windows that can be used on a PC, to monitor the usage of internet from that PC? It would need to include both browser and non-browser sources (e.g. a service that sync's calendar to gmail). So any software on your PC that uses would need to be configured to point to this local internet monitoring software/proxy. The monitoring software/proxy then would be configured to point to the company proxy server (address, port & credentials). Things that come to mind that might be close but not really focused on solving this might be perhaps: Charles Proxy, Fiddler 2, SQUID? The idea would be it could give you a daily/weekly/monthly report of internet upload/download usage on a per program/process/service basis for the PC it is being run on. thanks

  • a non recursive approach to the problem of generating combinations at fault

    - by mark
    Hi, I wanted a non recursive approach to the problem of generating combination of certain set of characters or numbers. So, given a subset k of numbers n, generate all the possible combination n!/k!(n-k)! The recursive method would give a combination, given the previous one combination. A non recursive method would generate a combination of a given value of loop index i. I approached the problem with this code: Tested with n = 4 and k = 3, and it works, but if I change k to a number 3 it does not work. Is it due to the fact that (n-k)! in case of n = 4 and k = 3 is 1. and if k 3 it will be more than 1? Thanks. int facto(int x); int len,fact,rem=0,pos=0; int str[7]; int avail[7]; str[0] = 1; str[1] = 2; str[2] = 3; str[3] = 4; str[4] = 5; str[5] = 6; str[6] = 7; int tot=facto(n) / facto(n-k) / facto(k); for (int i=0;i<tot;i++) { avail[0]=1; avail[1]=2; avail[2]=3; avail[3]=4; avail[4]=5; avail[5]=6; avail[6]=7; rem = facto(i+1)-1; cout<<rem+1<<". "; for(int j=len;j>0;j--) { int div = facto(j); pos = rem / div; rem = rem % div; cout<<avail[pos]<<" "; avail[pos]=avail[j]; } cout<<endl; } int facto(int x) { int fact=1; while(x0) fact*=x--; return fact; }

  • How do you portray to non programmers what programming involves?

    - by JD Isaacks
    I get casually asked a lot to take a couple days to teach someone how to program. Most people really think they can learn what I know in a few days. When I tell them I have been doing this for many years and I can't teach them to be a programmer in a few days, they look at me like I am being a jerk and just don't want to help them. I think this is because when I say I am a programmer, or I programmed this. I truly think most people do not realize that I mean I wrote the code that makes it up. I think that they think I mean I configured it, like when you say, "I programmed my VCR." Does anyone else think this? Whats your experience?

  • How can I give a basic idea of what I'm working on to a non programmer?

    - by Jesse
    As a relatively new programmer (1 year professionally, many years as an amateur) I've run into many situations that sent me running to Stack Overflow for answers that failed my meagre experiences. Tonight I received the hardest question ever. My wife asked me: What are you working on? The questions is deceptive in it's simplicity. A straight forward and truthful answer of "I'm working on a c# class module for monitoring database delivery times" is sure incite suggestion of attempts to confuse. My second instinct was to suggest that it couldn't really be explained to a layperson, after very brief consideration I came to the conclusion that this would likely result in a long and sleepless night on the sofa. The end result was a muddled answer along the lines of "something to monitor automatic things to make sure they're delivered on time". The reception was fairly chilly, I had to make many assurances that I was not insulting her ample intelligence. My question is thus, what is the best way to discuss your work as a programmer with your significant other who is not.

  • Is it possible to give an animated GIF a transparent background?

    - by Phil
    I'm making a Fire Emblem-esque game. There are very cute 2D frames I made for each character, and, like a game like Fire Emblem, I want these characters to animate constantly. To circumvent the graphics programming involved I came up with a novel idea! I would make each character an animated gif, and only in special conditions ever halt their constant movement - in that case just change what image is being displayed. Simple enough. But I have a dilemma - I want the background of my .gifs to be transparent (so that the "grass" behind each character naturally shows, as per the screenshot - which has them as still images with transparent backgrounds). I know how to make a background transparent in numerous tools (GIMP, Photoshop). But it seems every .gif creator replaces the transparent background with something and I can't edit it back to transparent. Is it possible to have a .gif with a transparent "background"? Perhaps my knowledge of file formats is limiting me here.

  • Non modal "status" form

    - by David Jenings
    At the beginning of a section of C# code that could take several seconds to complete, I'd like to display a non modal form with a label that just says, "Please wait..." WaitForm myWaitForm = null; try { // if conditions suggest process will take awhile myWaitForm = new WaitForm(); myWaitForm.Show(); // do stuff } finally { if (myWaitForm != null) { myWaitForm.Hide(); myWaitForm.Dispose(); myWaitForm = null; } } The problem: the WaitForm doesn't completely display before the rest of the code ties up the thread. So I only see the frame of the form. In Delphi (my old stomping ground) I would call Application.ProcessMessages after the Show() Is there an equivalent in C#? Is there a canned "status" form that I can use in situations like this? Is there a better way to approach this? Thanks in advance. David Jennings

  • InvalidAttributeValueException when using non-ascii characters in JNDI

    - by matdan
    Hi, I have some trouble using JNDI since it accepts only 7-bits encoded parameters. I am trying to change an LDAP entry using JNDI with the following code : Attribute newattr = new BasicAttribute("userpassword", password); ModificationItem[] mods = new ModificationItem[1]; mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, newattr); context.modifyAttributes("uid=anID,ou=People,o=MyOrganisation,c=com", mods); If my password contains only ascii characters, it works perfectly, but if I use a non-ascii character, like "à", I have this error message : javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - The value is not 7-bit clean: à]; My ldap supports those characters so I guess it comes from JNDI. Does anyone know how to fix that? Am I supposed to convert my parameter? How can I do that easily? Thanks

  • Non-Relational DBMS Design Resources

    - by Matt Luongo
    Hey guys, As a personal project, I'm looking to build a rudimentary DBMS. I've read the relevant sections in Elmasri & Navathe (5ed), but could use a more focused text. The rub is that I want to play with novel non-relational data models. While a lot of E&N was great- indexing implementation details in particular- the more advanced DBMS implementation was only targeted to a relational model. I could also use something a bit more practical and detail-oriented, with real-world recommendations. I'd like to defer staring at DBMS source for a while if I can. Any ideas?

  • A window that behaves both modally and non-modally

    - by Chris
    I want to create a WPF window that behaves as a modal dialogue box while at the same time facilitating selected operations on certain other windows of the same application. An example of this behaviour can be seen in Adobe Photoshop, which offers several dialogues that allow the user to use an eyedropper tool to make selections from an image while disabling virtually all other application features. I'm guessing that the way forward is to create a non-modal, always-on-top dialogue and programmatically disable those application features that are not applicable to the dialogue. Is there an easy way to achieve this in WPF? Or perhaps there's a design pattern I could adopt.

  • Oracle Database Security Protecting the Oracle IRM Schema

    - by Simon Thorpe
    Acquiring the Information Rights Management technology in 2006 was part of Oracle's strategic security vision and IRM compliments nicely the overall Oracle security set of solutions. A year ago I spoke about how Oracle has solutions that can help companies protect information throughout its entire life cycle. With our acquisition of Sun this set of solutions has solidified and has even extended down to the operating system and hardware level. Oracle can now offer customers technology that protects their data from the disk, through the database to documents on the desktop! With the recent release of Oracle IRM 11g I was tasked to configure demonstration and evaluation environments and I thought it would make a nice story to leverage some of the security features in the latest release of the Oracle Database. After building these environments I thought I would put together a simple video demonstrating how both Database Advanced Security and Information Rights Management combined can provide a very secure platform for protecting your information. Have a look at the following which highlights these database security options.Transparent Data Encryption protecting the communication from the Oracle IRM server to the Database server. Encryption techniques provide confidentiality and integrity of the data passing to and from the IRM service on the back end. Transparent Data Encryption protecting the Oracle IRM database schema. Encryption is used to provide confidentiality of the IRM data whilst it resides at rest in the database table space. Database Vault is used to ensure only the Oracle IRM service has access to query and update the information that resides in the database. This is an excellent method of ensuring that database administrators cannot look at or make changes to the Oracle IRM database whilst retaining their ability to administrate the database. The last thing you want after deploying an IRM solution is for a curious or unhappy DBA to run a query that grants them rights to your company financial data or documents pertaining to a merger or acquisition.

  • What are good NoSQL and non-relational database solutions for audit/logging database

    - by Juha Syrjälä
    What would be suitable database for following? I am especially interested about your experiences with non-relational NoSQL systems. Are they any good for this kind of usage, which system you have used and would recommend, or should I go with normal relational database (DB2)? I need to gather audit trail/logging type information from bunch of sources to a centralized server where I could generate reports efficiently and examine what is happening in the system. Typically a audit/logging event would consist always of some mandatory fields, for example globally unique id (some how generated by program that generated this event) timestamp event type (i.e. user logged in, error happened etc) some information about source (server1, server2) Additionally the event could contain 0-N key-value pairs, where value might be up to few kilobytes of text. It must run on Linux server It should work with high amount of data (100GB for example) it should support some kind of efficient full text search It should allow concurrent reading and writing It should be flexible to add new event types and add/remove key-value pairs to new events. Flexible=no changes should be required to database schema, application generating the events can just add new event types/new fields as needed. it should be efficient to make queries against database. For reporting and exploring what happened. For example: How many events with type=X occurred in some time period. Get all events where field A has value Y. Get all events with type X and field A has value 1 and field B is not 2 and event occurred in last 24h

  • How to non-greedy multiple lookbehind matches

    - by ArtK
    Source: <prefix><content1><suffix1><prefix><content2><suffix2> Engine: PCRE RegEx1: (?<=<prefix>)(.*)(?=<suffix1>) RegEx2: (?<=<prefix>)(.*)(?=<suffix2>) Result1: <content1> Result2: <content1><suffix1><prefix><content2> The desired result for RegEx2 is just <content2> but it is obviously greedy. How do I make RegEx2 non-greedy and use only the last matching lookbehind? [I hope I have translated this correctly from the NoteTab syntax. I don't do much RegEx coding. The <prefix>, <content> & <suffix> terms are just meant to represent arbitrary strings. Only the "<" in the "?<=" lookbehind command is significant.] I suspect it is something simple but after too many hours of searching I'm giving up on solving it myself. Thanks for the help Art

  • Replacing characters in a non well-formed XML body

    - by ryanprayogo
    In a (Java) code that I'm working on, I sometimes deal with a non well-formed XML (represented as a Java String), such as: <root> <foo> bar & baz < quux </foo> </root> Since this XML will eventually need to be unmarshalled (using JAXB), obviously this XML as is will throw exception upon unmarshalling. What's the best way to replace the & and the < to its character entities? For &, it's as easy as: xml.replaceAll("&", "&amp;") However, for the < symbol, it's a bit tricky since obviously I don't want to replace the < that's used for the XML tag opening 'bracket'. Other than scanning the string and manually replacing < in the XML body with &lt;, what other option can you suggest?

  • How to make WPF DataGrid Column Header transparent

    - by joerage
    Hi, I am trying to make the column header of my WPF Datagrid to be transparent. I am able to set it to a color without problem, but I can't have it transparent. Here is what I tried: <Style x:Key="DatagridColumnHeaderStyle" TargetType="{x:Type tk:DataGridColumnHeader}"> <Setter Property="Background" Value="Transparent" /> <Setter Property="Foreground" Value="#C2C4C6" /> </Style> <Style x:Key="DashboardGridStyle" TargetType="{x:Type tk:DataGrid}"> <Setter Property="ColumnHeaderStyle" Value="{StaticResource DatagridColumnHeaderStyle}" /> <Setter Property="Background" Value="Transparent" /> <Setter Property="RowBackground" Value="Transparent" /> </Style> <tk:DataGrid Style="{StaticResource DashboardGridStyle}" > ... </tk:DataGrid> With this code, it seems to take the default brush. What am I missing?

  • R ggplot2: Arrange facet_grid by non-facet column (and labels using non-facet column)

    - by tommy-o-dell
    I have a couple of questions regarding facetting in ggplot2... Let's say I have a query that returns data that looks like this: (note that it's ordered by Rank asc, Alarm asc and two Alarms have a Rank of 3 because their Totals = 1798 for Week 4, and Rank is set according to Total for Week 4) Rank Week Alarm Total 1 1 BELTWEIGHER HIGH HIGH 1000 1 2 BELTWEIGHER HIGH HIGH 1050 1 3 BELTWEIGHER HIGH HIGH 900 1 4 BELTWEIGHER HIGH HIGH 1800 2 1 MICROWAVE LHS 200 2 2 MICROWAVE LHS 1200 2 3 MICROWAVE LHS 400 2 4 MICROWAVE LHS 1799 3 1 HI PRESS FILTER 2 CLOG SW 1250 3 2 HI PRESS FILTER 2 CLOG SW 1640 3 3 HI PRESS FILTER 2 CLOG SW 1000 3 4 HI PRESS FILTER 2 CLOG SW 1798 3 1 LOW PRESS FILTER 2 CLOG SW 800 3 2 LOW PRESS FILTER 2 CLOG SW 1200 3 3 LOW PRESS FILTER 2 CLOG SW 800 3 4 LOW PRESS FILTER 2 CLOG SW 1798 (duplication code below) Rank = c(rep(1,4),rep(2,4),rep(3,8)) Week = c(rep(1:4,4)) Total = c( 1000,1050,900,1800, 200,1200,400,1799, 1250,1640,1000,1798, 800,1200,800,1798) Alarm = c(rep("BELTWEIGHER HIGH HIGH",4), rep("MICROWAVE LHS",4), rep("HI PRESS FILTER 2 CLOG SW",4), rep("LOW PRESS FILTER 2 CLOG SW",4)) spark <- data.frame(Rank, Week, Alarm, Total) Now when I do this... s <- ggplot(spark, aes(Week, Total)) + opts( panel.background = theme_rect(size = 1, colour = "lightgray"), panel.grid.major = theme_blank(), panel.grid.minor = theme_blank(), axis.line = theme_blank(), axis.text.x = theme_blank(), axis.text.y = theme_blank(), axis.title.x = theme_blank(), axis.title.y = theme_blank(), axis.ticks = theme_blank(), strip.background = theme_blank(), strip.text.y = theme_text(size = 7, colour = "red", angle = 0) ) s + facet_grid(Alarm ~ .) + geom_line() I get this.... Notice that it's facetted according to Alarm and that the facets are arranged alphabetically. Two Questions: How can I can I keep it facetted by alarm but displayed in the correct order? (Rank asc, Alarm asc). Also, how can I keep it facetted by alarm but show labels from Rank instead of Alarm? Note that I can't just facet on Rank because ggplot2 would see only 3 facets to plot where there are really 4 different alarms. Thanks kindly for the help! Tommy
