  • Selenium: How to enter white space as the value of a text field?

    - by Andrew
    I have a form text field that is being populated with a default value. I would like to clear the value and enter white space to assert that the expected validation occurs. I am using Selenium RC and the PHPUnit Selenium extension. How can I achieve this? Note: I have already tried doing these, but they do not work: $this->type('FirstName', " "); //spaces $this->type('FirstName', "\t"); //tab character They clear the value from the field, but they do not enter the white space into the field.

  • Matlab: How to find the right-most point of a white line within the imrect?

    - by mchlfchr
    i've got a question regarding the imrect() function, which is part of the image processing toolbox in MatLab. I'd like to find a starting point within an image. I use the imrect function for setting a region to limit and specify the lookup area, but I can't get the point where the ROI mask is getting back mapped to the original size of the image. As you can see on the image there is a specified rectangle (cyan-colored), which I want to inspect for the white line, especially the nearest point to the right edge of the rectangle. I experimentated with only looking up on the last column of the rectangle, but as I mentioned before, the re-mapping onto the global image coordinates failed. So in this example, the white point I'd like to get would be around (98,302) The original (x,y) coordinates are relevant, so a cropping of the image to the rectangle is not acceptable. So, do you have any ideas? Thanks for any helping comments. Kind regards,

  • How to get rid of this sliver of white between DIVs?

    - by George Edison
    I am currently having trouble getting rid of a sliver of white... Here is an example page: http://m.stackoverflow.quickmediasolutions.com/view_question.php?id=97969&site=serverfault As you can see, the answers have a sliver of white stuffed between the top of the 'button' and the content. Here is some relevant code: <!-- this is the top of the 'button' --> <div class='top'></div> <!-- right here is where the space is --> <div class='content'></div> .top { height: 5px; } .content { display: block; padding-left: 10px; }

  • How do I make an on-screen HUD in libgdx?

    - by Devin Carless
    I'm new to libgdx, and I am finding I am getting stumped by the simplest of things. It seems to want me to do things a specific way, but the documentation won't tell me what that is. I want to make a very simple 2d game in which the player controls a spaceship. The mouse wheel will zoom in and out, and information and controls are displayed on the screen. But I can't seem to make the mouse wheel NOT zoom the UI. I've tried futzing with the projection matrices in between Here's my (current) code: public class PlayStage extends Stage { ... public void draw() { // tell the camera to update its matrices. camera.update(); // tell the SpriteBatch to render in the // coordinate system specified by the camera. spriteBatch.setProjectionMatrix(camera.combined); spriteBatch.begin(); aButton.draw(spriteBatch, 1F); playerShip.draw(spriteBatch, 1F); spriteBatch.end(); } } camera.zoom is set by scrolled(int amount). I've tried about a dozen variations on the theme of changing the camera's projection matrix after the button is drawn but before the ship is, but no matter what I do, the same things happen to both the button and the ship. So: What is the usual libgdx way of implementing an on-screen UI that isn't transformed by the camera's projection matrix/zoom?

  • Why does Ubuntu gets stuck on the loading screen?

    - by mohit
    I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH with Windows 7 previously installed. Sometimes when I try to boot Ubuntu, it gets stuck at loading screen. There seems to be some problem with driver (as far I can judge). Following is the log generated, when I press Esc during the boot (before the problem occurs): ... * Stopping System V initialization compatibility [ok] * Starting System V runlevel compatibility [ok] * Starting crash report submission daemon [ok] * Starting automatic crash report generation [ok] ... ... * Starting LightDM Display Manager [ok] Nothing works after that, no Esc, etc, except restart. Also I've observed the following: Inactivity of Hard-drive (Led doesn't glows). Flashing, or blinking, of Caps-lock and Scroll-lock On restart, Ubuntu seem to load successfully. However, the loading screen has somewhat basic graphics. This problem started after I installed Additional drivers: NVIDIA accelerated graphics driver Also, most of the times Ubuntu loads without any problem. However, it is annoying to restart everytime it fails. So my question is: Why this happens and what is the solution?

  • How do I fix a garbled screen on a Gateway LT3103u?

    - by paracaudex
    I've been having garbled screen problems on a Gateway LT3103u on Ubuntu for a while. I just did a fresh install of Ubuntu 11.10 and continue to have issues. I installed xubuntu-desktop in case the issues had to do with the sophisticated GNOME graphics. The problem is less bad, but it's still there. After a few minutes of using XFCE, the screen gets garbled. I assume this has something to do with the graphics card, but I don't know how to go about troubleshooting something like this. Where should I start? Update: Here is the description of the VGA card from lspci -vvv: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 028c Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: radeon Kernel modules: radeon Update: Setting GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub seems to have fixed it in both Ubuntu and xubuntu-desktop. I will test it for a day or so to see if the problems recur and then post more detail with some links to an explanation. Update 2: It is possible to use this fix for Nvidia card (GTX 260) when graphics is defective after 11.10 upgrade/install? First few restarts was graphic ok, then after few restarts begins suddenly be defective and it stay so. I must returned to 11.04 because this problem and I wait for 12.04. So I hope in this fix.

  • Misaligned Display on Resume

    - by Shaun Killingbeck
    I have an odd issue with my laptop display when resuming from suspend. When I have an additional monitor connected there is no issue. However without an additional monitor connected, after resuming only the left 10% of the laptop screen (just enough to show the Unity Launcher and a bit more) is visibly working, although strangely in a screenshot this same 10% is shown on the right hand side of the screenshot: I ran xrandr --verbose before and after resume, and the only difference (using diff) was: 2c2 < LVDS connected 1366x768+0+0 (0x98) normal (normal left inverted right x axis y axis) 344mm x 194mm --- > LVDS connected 1366x768+1280+0 (0x98) normal (normal left inverted right x axis y axis) 344mm x 194mm This seems to suggest the screen position has been shifted by 1280 horizontally, the width of the second monitor I use. Indeed, running the command xrandr --output LVDS --pos 0x0 does bring the screen back to normal. However, I don't want to have to run this command every time, I'd prefer to cure the source of the problem than just correct the symptoms. Any ideas on how to get Ubuntu to keep the display configuration settings from before suspend when it resumes? or why it changes at all?

  • Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

    - by Estel
    A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige. Additional information: Intel Core2 Duo e6400 2.13GHz nVidia GeForce 7-series (7900 GS) 4 GB DDR2 333MHz (2x 2GB) Dell XPS 410 BIOS Revision 2.5.3

  • Is there a standard way to track 2d tile positions both locally and on screen?

    - by Magicked
    I'm building a 2D engine based on 32x32 tiles with OpenGL. OpenGL draws from the top left, so Y coordinates go down the screen as they increase. Obviously this is different than a standard graph where Y coordinates move up as they increase. I'm having trouble determining how I want to track positions for both sprites and tile objects (objects that are collections of tiles). My brain wants to set the world position as the bottom left of the object and track every object this way. The problem with this is I would have to translate it to an on screen position on rendering. The positive with this is I could easily visualize (especially in the case of objects made of multiple tiles) how something is structured and needs to be built. Are there standard ways for doing this? Should I just suck it up and get used to positions beginning in the top left? Here are the OpenGL calls to start rendering: // enable textures since we're going to use these for our sprites glEnable(GL_TEXTURE_2D); glClearColor(0.0f, 0.0f, 0.0f, 0.0f); // enable alpha blending glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); // disable the OpenGL depth test since we're rendering 2D graphics glDisable(GL_DEPTH_TEST); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, WIDTH, HEIGHT, 0, 1, -1); glMatrixMode(GL_MODELVIEW); I assume I need to change: glOrtho(0, WIDTH, HEIGHT, 0, 1, -1); to: glOrtho(0, WIDTH, 0, HEIGHT, 1, -1);

  • What You Said: Are You A Second Screen Multi-Tasker?

    - by Jason Fitzpatrick
    Earlier this week we asked you if you used a second screen while watching television or movies–such as a smartphone or tablet. Now we’re back to highlight how HTG readers are engaging (or disengaging) with their mobile devices. Image courtesy of Umani, a TV-companion application for iPad. By far and away the biggest trend was the use of the second screen as a filler for commercials and/or and outright diversion from lackluster programming. Jack in TN writes: Yes. I keep a laptop going 7×24 pretty much, and TV in going normally. Pretty much my ‘throne’ in the family room. I have almost always multi-tasked, before laptop it was a book or magazine or 3 at my side. My wife has accused me of using TV as a radio more than once, and I can’t say she is wrong.

  • Why is my hg workbench & Adobe Reader toolbar icon a blank white page?

    - by Zasurus
    On my work's PC (windows 7 32bit) all Adobe Reader and hg Workbench icons on the toolbar (and general shortcuts for hg workbench) are just white pages (with the top left corner folded over). If you right click on the toolbar icon then right click on "TortoiseHg Workbench"(for hg workbench) then "Properties" then the "Change Icon..." button is greyed out (same for "Adobe Reader X"). Also the "Target:" is "TortoiseHg 2.4.0 (x86)" and is greyed out also the "Open File Location" is greyed out. This is the same for both Hg Workbench and Adobe Reader and seems to be the only thing that connects them. I have tried reinstalling to no avail. I also have local admin rights on the PC. I finally I have tried the following following questions without any luck (they aren't quite relevant to my issue but close): Adobe Reader program icon and pdf icons don't appear in Windows 7 Adobe PDF icon disappeared? Encase my description isn't enough to understand the issue here is a screenshot. As you can see the Hg Workbench icon (far left) and a pdf open in Adobe Reader X (second icon to from the left) are both blank and the shortcut is mainly greyed out.

  • Is a confirmation screen necessary for an order form?

    - by abeger
    In a discussion about how to streamline an order form on our site, the idea of eliminating the confirmation screen. So, instead of filling out the form, clicking "Submit", seeing a summary on a confirmation screen and clicking "Confirm", the user would simply fill out the form, hit "Submit", and the order's done. The theory is that fewer clicks and fewer screens means less time to order and therefore the ordering experience is easier. The opposing opinion says that without the confirmation screen, user error increases and people just end up canceling/changing orders after the fact. I'm looking for more input from the SO community. Have you ever done this? How has it worked out, compared to a traditional confirmation screen setup? Are there examples of a true "one click and done" setup on the web (does Amazon's 1-click have a confirmation screen? I've never been courageous enough to try it)? EDIT: Just to clarify, when I say "confirmation screen", I mean a second step where the customer reviews the order before placing it. Even if we did do away with it, the user would still receive a message saying "your order has been placed".

  • Windows Screensaver Multi Monitor Problem

    - by Bryan
    I have a simple screensaver that I've written, which has been deployed to all of our company's client PCs. As most of our PCs have dual monitors, I took care to ensure that the screensaver ran on both displays. This works fine, however on some systems, where the primary screen has been swapped (to the left monitor), the screensaver only works on the left (primary) screen. The offending code is below. Can anyone see anything I've done wrong, or a better way of handling this? For info, the context of "this", is the screensaver form itself. // Make form full screen and on top of all other forms int minY = 0; int maxY = 0; int maxX = 0; int minX = 0; foreach (Screen screen in Screen.AllScreens) { // Find the bounds of all screens attached to the system if (screen.Bounds.Left < minX) minX = screen.Bounds.Left; if (screen.Bounds.Width > maxX) maxX = screen.Bounds.Width; if (screen.Bounds.Bottom < minY) minY = screen.Bounds.Bottom; if (screen.Bounds.Height > maxY) maxY = screen.Bounds.Height; } // Set the location and size of the form, so that it // fills the bounds of all screens attached to the system Location = new Point(minX, minY); Height = maxY - minY; Width = maxX - minX; Cursor.Hide(); TopMost = true;

  • How to accommodate for the next iPhones totally different screen resolution?

    - by mystify
    This is a programming question! Read on before you vote to close! According to Gizmodo, the next iPhone will have a new screen resolution: The 3.5-inch screen has a resolution of 960?×?640 pixels This little detail affects our apps in a heavy way. Most of the demo apps on the net have one thing in common: They position views in the believe that the screen has a fixed size of 320 x 480 pixels. So what most -if not all- developers do is: They designed everything in such a way, that a touchable area is -for example- 50 x 50 pixels big. Just enough to tap it. Things have been positioned relative to the upper left, to reach a specific position on screen - let's say the center, or somewhere at the bottom. So the big question is: How will the developers compensate their layout and graphics? Are there already solutions which can be used to calculate coordinates and sizes in a normalized manner, which then appear to be exactly the same when viewing them on a screen of any resolution, assuming at least that the aspect ration won't change? This is community wiki. Just add anything that you think is relevant to this huge problem (constant screen res was one of the main reasons why I didn't go for Android!!).

  • Creating 1 page PDF of iPad Screen view - How?

    - by user314695
    Hi All, I've asked this question on a couple other forums and have had zero response, so I'm hoping someone here can help point me in the right direction. I have a pretty simple one screen application for my work. It's basically just a recreation of a 1 page paper report that has a company logo, some labels, a few text boxes and a scroll text box for the report. I need to be able to fill out the report then click a button to save it in a graphical form so I can fax, print or email it later. Currently, I'm just programmatically taking a screen capture and saving it to the photo's library (default for screen capture). Then I can just email it from photo's. This works ok, but is kind of hacky, at best. I've read through the new iPad 3.2 guide for creating PDF's (apparently it's supposed to be much easier than before) but I can not get it to work and I've spent countless hours on it now. I'm hoping someone has the answer for me. Alternatively, if anyone knows how I can redirect where the screen capture is stored (default is in the photo album) then maybe I can make that function work. If I could redirect the screen capture to store in my applications document folder, then I can use MFMailCompose to attach it to an email. Lastly, on a side note, does anyone know of a good way to capture a digital signature via touch. For instance, I'd love to have my users be able to just sign their name via touch at the bottom of the document before I convert to PDF or take a screen capture. Thanks in advance for your help. -Ray

  • How would I be able to get a game over screen using the pause function?

    - by Joachim Velzel
    I am having problems with my snake game, when the snake collides with itself it draws a "game over" image in the background, but only while it's colliding with itself. I want it to behave like the pause function, so that as soon as the snake collides with itself it draws an image on the screen and stops the game play. And then how would you be able to restart or to quit the game? I just have this for the detection at the moment: if (snakeHeadRectangle.Intersects(snakeBodyRectangleArray[bodyNumber])) { spriteBatch.Draw(textureGameOver, gameOverPosition, Color.White); } Thanks

  • How do you change your screen's color temperature in Ubuntu?

    - by RPG Master
    I edit my photos on my laptop (yes, I know they have crap displays) and I recently had to replace the screen because the old one just randomly died. The old one had decent color reproduction by default, but this new one is VERY blue. After playing with the Gamma I've gotten it to be a bit better, but it's still pretty blue. So, my question is, how do I go about changing my laptop's display's color temperature? And I don't mean through something like the Red, Green, Blue sliders in the NVIDIA config menu. I'm talking about like adjusting in degrees, like editing a photo's white balance. EDIT: So now I've found Redshift and it's doing me pretty good. I thought it might be helpful if I out here the command I'm using. redshift -t 5000:5000 -g .5 By adding this to my start up commands I should be good. I'm still open to other suggestions, because I'd like something that actually edited my xorg.conf or something like that.

  • How do I make Ubuntu go past the splash screen?

    - by John Baber
    I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with ubntu and the dots turning from white to orange forever. This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash. dmesg cat kern.log

    When doing screen recording, I can get a frame rate of maybe 15 frames per second for the full screen on my 1080p monitor using the XVID codec. I can increase the speed a bit by recording a region, changing screen modes, and tweaking other settings, but I'm curious what hardware upgrades might give me the biggest bang for my buck. My PC is budget, but modern... Athlon 2 X4 645 (3.1GHz, quad core, limited cache) processor. 4GB single channel DDR3 1066 RAM. ASRock motherboard with NVidia GeForce 7025/nForce 630a Chipset. ATI Radeon HD 5450 graphics card - 512MB on board, not configured to steal system RAM. I dual-boot Windows XP and Windows 7. For the moment, XP is my bigger performance concern as it's still my getting-things-done O/S as opposed to my browser-host O/S. My goal is to make a few programming-related tutorials. For a lot of that I don't need screen recording - I can make up some slides, record audio with the PC switched off, yada yada. When I do need screen recording, I'll mostly be recording Notepad++, Visual Studio or a command prompt. Occasionally, I may be recording some kind of graphics or diagram program and using my pre-Bamboo cheap Wacom tablet - I have the CS2 versions of Photoshop and Illustrator, but I'd much more likely be using Microsoft Paint. Basically, what I'll be recording won't be making huge demands on the machine - but recording a fair number of pixels (720p preferred) will be useful. What's particularly wierd - not so long ago I still had a five-year-old Pentium 4 based PC. And (with the same 1080p monitor) it could record at not far from the same frame rate. So clearly the performance issues are more subtle than just throw-money-at-it. My first guess would be that the main bottleneck is the bandwidth for transferring data to/from the graphics card. Is that likely to be correct? In support of that, see this [Radeon HD 5450 review][1] - the memory bandwidth is only 12.8 GB/s. If you can't get data out of graphics memory quickly, you can't transfer it back to the system memory quickly. Apparently, that's slower than some top-end cards in 2002.
