• XFCE session with GNOME in background

  - by 100rabh

  Hi askUbuntu I recently installed XFCE on my Ubuntu 10.04 and it runs finely but with an issue. Everytime I login into my XFCE session I see the background image of GNOME session and after few seconds it disappears which gives me the impression that XFCE session is running over an already running GNOME session. If that is really the case then it might also be eating into my system's RAM which could be a bug. All helps and suggestions are welcome.

• Css menu hovering background color problem

  - by Guisasso

  i have a very simple question for many, but complicated enough for me. I have tried to fix this for the last hour with no luck. I downloaded a css menu, and made all the modifications needed to me with no issue, but there's one thing that i'm having no luck trying to fix: When hovering over "ccc" (for example), and going down to 1 for example (this happens to all other cells) the black background doesn't extend all the way to the right. Here's the link: http://riversidesheetmetal.net/gui/questions/aaa.html

• La vulnérabilité de Java déjà exploitée depuis des serveurs russes, Oracle reste sur sa position

  Mise à jour du 15/04/10 La vulnérabilité de Java déjà exploitée Depuis des serveurs russes, Oracle reste sur sa position La faille de Java récemment mise à jour par un ingénieur de Google (lire ci-avant) serait déjà exploitée. Roger Thompson, chef chercheur chez AVG, a repéré des attaques depuis des serveurs russes utilisés par des sites qui ciblent le grand public (comme Songlyrics.com, qui propose les paroles de chansons de Lady Gaga, Rihanna, etc.). En arrivant sur ce site, un iFrame malicieux camouflé dans une publicité redirige l'utilisateur (sans que celui-ci ne s'en aperçoive) vers un serveur hébergeant l'exploit....

• isometric background that covers the viewport [on hold]

  - by Richard

  The background image should cover the viewport. The technique I use now is a loop with an innerloop that draws diamond shaped images on a canvas element, but it looks like a rotated square. This is a nice example: ,that covers the whole viewport. I have heard something about clickthrough maps, but what more ways are there that are most efficient with mobile devices and javascript? Any advice in grid design out there?.

• Repeat a part of spritesheet as background

  - by Moiblpadde

  So I'm trying to repeat a part of my spritesheet as a background (js, canvas). My code so far: var canvas = $("#board")[0], ctx = canvas.getContext("2d"), sprite = new Image(); sprite.src = "spritesheet.png"; sprite.onload = function(){ ctx.fillStyle = ctx.createPattern(spriteBg, "repeat"); ctx.fillRect(0, 25, 500, 500); } This is fine, but as you can see, it repeat the whole sprite, not just a part of it, and I just can't figure out how to do it D:

• Making headers readable on a multi colored background

  - by aslum

  So the client wants a multi-colored background (think 4 colors of paint splats randomly all over the page. Because of this the headers are a bit hard to read. I've currently got them set up as black text with some white drop shadow, but it's still pretty hard to read in IE. How can I make the headers legible regardless of what is behind them (it's a CMS so position on the page is liable to change regularly)?

  I am trying to get a sprite to position itself at the center of the screen but nothing seems to be working for me. I'm trying Viewport viewport = graphics.GraphicsDevice.Viewport; logoPosition = new Vector2((viewport.Width - towerImage.Width) / 2, (viewport.Height - towerImage.Height) / 2); and spriteBatch.Draw(towerImage, centre, null, Color.White, 0, baseOrigin, 1.0f, SpriteEffects.None, 0); This is my first time using XNA and I don't really have a clue what I'm doing.

• Taking too long to get skills for entry level programmer position [closed]

  - by greenonion

  I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

• Transition Player Position

  - by Lycrios

  I'm currently working on a java MMO with a pretty solid start, but I've come across an issue I need a little help with. I'm working on player position's. Meaning there X/Y on the screen, if the PlayerA has a higher FPS(Frames Per Second) then other players, the resulting action will be that PlayerA will move faster than everyone else. I know the reasoning for this, it's because when the game draws I just use: x++; What would a better method be?

• How to set background image for Android button but keep the gray button?

  - by Jason Whiler

  I need to set a background image for an android button (text button), but I want to keep the gray button. When i use the setBackgroundResource() it has the image in place of the gray button. How can I keep the gray button? I tried using setCompoundDrawablesWithIntrinsicBounds, but the image only takes up part of the button, even when I have no text. Notes: I will not have text while I display the image, but the button needs to be a TextButton because there will be text without images at times, and images with text at others.

• MediaElement.Position behaviour and Windows Phone 7 issue

  - by RoguePlanetoid

  I have a problem, I have written a simple Media Player for Windows Phone 7 and can Play, Stop and control the Volume of a Video (loaded from a URI) however when I try to set the position, this causes the application to freeze. I have used both these lines, but either does not work: Player.Position = new TimeSpan(0, 0, 0, 0, (int)Position.Value); Player.Position = TimeSpan.FromSeconds((int)(Position.Value)); I do have this event handler: void Player_MediaOpened(object sender, RoutedEventArgs e) { Position.Maximum = Player.NaturalDuration.TimeSpan.TotalMilliseconds; } And have tried using the Seconds value, casting to Ints etc, however everytime I try to set the Position, the app freezes. The video otherwise plays normally - anyone know what the problem may be here?

• CSS3 gradient background set on body doesn't stretch but instead repeats?

  - by John Isaacks

  ok say the content inside the <body> totals 300px high. If I set the background of my <body> using -webkit-gradient or -moz-linear-gradient Then I maximize my window (or just make it taller than 300px) the gradient will be exactly 300px tall (the height of the content) and just repeat to fill the rest of the window. I am assuming this is not a bug since it is the same in both webkit and gecko. But is there a way to make the gradient stretch to fill the window instead of repeat?

• Make input field background image disappear after text is inputted

  - by aslum

  I'd like to make the background image for my input field disappear once the user has typed any amount of text in it. Is there a simple way to do that in javascript? I can get it so the bg disappears while the field is focused, but then it returns once they move on to the next field. HTML: Call me at <input name="phone" type="text" class="phone-field" id="phone"> CSS: .form input { background-color:transparent; } .form input:focus { background-color:#edc; background-image:none; } input.phone-field { background-image: (url/images/phonebg.png); background-repeat: no-repeat; background-position: left 1px; }

• table cell background color change problem

  - by Mellon

  I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

• How to create a win32 application without window in background with C?

  - by user563413

  The application do not need any window or console. It can be a console application if the console window can be removed or can be put into background. The application will do some simple tasks(such as cleaning rubbish files) and exit. I hope that the application should not be a windows service if possible. I hope that the application can be started with double-click in explorer window and run silently. When the application is running, I hope that the mouse cursor should not be changed to hourglass shape. That is to say, do not disturb the user when the application is running. Just run and exit silently. DO NOT NEED to run it when windows starts or user logins. I hope this can be done in C if possible. What should I do? Thanks!

• Why is my background image not displaying properly in IE7?

  - by JAG2007

  Screenshot of the issue: here Webpage in Question: http://cure.org Offending browser: Internet Explorer 7 You'll notice from the screenshot, or if you view this site in IE7, that the background image is not displaying for the content div (#modal-inner-content). Strangely, the image displays in the other divs where it is used (since it's a sprite, I'm using that same image for #modal-top-border and #modal-btm-border). In all other browsers it displays properly, and even in IE8. I cannot seem to find what CSS rule (or lack thereof) I may be using that IE7 is choking on. NOTE: in order to get the modal screen, just click the link at the very top banner of the page that says "login to your CURE account

• What size should the background image in an MSI be?

  - by r_

  I am trying to create a Windows Installer package using Wix. I'm getting a lot of conflicting information about what size my custom background should be--the Wix documentation suggests a size of 500 x 314 pixels, but this leads to slight image distortion in the installer. I believe that I may be indirectly using the SplashBitmap property in Windows Installer, whose documentation suggests 480 x 320 is the correct size. When I try to use this image size, I also get artefacts in the image. Could anyone tell me what the correct size should be?

• Computing pixel's screen position in a vertex shader: right or wrong?

  - by cubrman

  I am building a deferred rendering engine and I have a question. The article I took the sample code from suggested computing screen position of the pixel as follows: VertexShaderFunction() { ... output.Position = mul(worldViewProj, input.Position); output.ScreenPosition = output.Position; } PixelShaderFunction() { input.ScreenPosition.xy /= input.ScreenPosition.w; float2 TexCoord = 0.5f * (float2(input.ScreenPosition.x,-input.ScreenPosition.y) + 1); ... } The question is what if I compute the position in the vertex shader (which should optimize the performance as VSF is launched significantly less number of times than PSF) would I get the per-vertex lighting insted. Here is how I want to do this: VertexShaderFunction() { ... output.Position = mul(worldViewProj, input.Position); output.ScreenPosition.xy = output.Position / output.Position.w; } PixelShaderFunction() { float2 TexCoord = 0.5f * (float2(input.ScreenPosition.x,-input.ScreenPosition.y) + 1); ... } What exactly happens with the data I pass from VS to PS? How exactly is it interpolated? Will it give me the right per-pixel result in this case? I tried launching the game both ways and saw no visual difference. Is my assumption right? Thanks. P.S. I am optimizing the point light shader, so I actually pass a sphere geometry into the VS.
