• How to blacklist Terminal Services startup environment setting?

  - by JBurace

  I have a user in Active Directory who uses this setting in the Environment tab: Start the following program at logon: "C:\Program Files\PName\Folder\gui.exe" This runs okay on various computers (that are on the domain) including his own. But the user needs to RDP into a Windows Server which does not have this program (which is normal). When the user RDPs into the server and logs in with the AD account, an error occurs about C:\Program Files\PName\Folder\gui.exe missing and the user then gets stuck at a grey screen. The user needs to RDP into this server; how can one blacklist that Environment setting from activation on a specific machine on the domain?

• Problem with scrolling background in one OpenGL loop

  - by GvS

  I have 960x3000 map image in png and I'm scrolling it in a loop like this (it's called in 60 FPS loop): glPushMatrix(); glBindTexture( GL_TEXTURE_2D, mapTex[iBgImg]); glBegin(GL_QUADS); double mtstart = 0.0f - fBgVPos/(double)BgSize; double mtend = mtstart + mtsize; glTexCoord2d(0.0, mtstart); glVertex2f(fBgX, TOP_MARGIN); glTexCoord2d(1.0, mtstart); glVertex2f(fBgX + MAP_WIDTH, TOP_MARGIN); glTexCoord2d(1.0, mtend); glVertex2f(fBgX + MAP_WIDTH, BOTTOM_MARGIN); glTexCoord2d(0.0, mtend); glVertex2f(fBgX, BOTTOM_MARGIN); glEnd(); glPopMatrix(); unfortunately it isn't smooth when the game is in windowed mode. However, it is smooth in full screen mode. I'm using GLFW for windows. Maybe there is something wrong with my method? Is there anything better? Or could this be hardware problem? Edit: Window is created using glfwOpenWindowHint(GLFW_WINDOW_NO_RESIZE, GL_TRUE); glfwOpenWindowHint(GLFW_REFRESH_RATE, 60); and main loop is using glfwSwapInterval(1) to ensure 60 FPS;

• FreeBSD 9 (amd64) reboot/shutdown process is very slow

  - by nbari

  I have a Dell Poweredge 2900 III with FreeBSD 9 (amd64), the server uses mfi wich handles a raid10, I had to reboot the server, but notice that either when rebooting or shutting down the server, something is going wrong, besides taking to much time to reboot/shutdown, after rebooting I notice that that some ldap instances within some jails could'nt start and this was because the database was corrupted. This make me think that probably something was wrong with the disks or mfi card, but checking the disk array / logs everything seems to be working fine. My set up is something like this: Host server has the minimum base of FreeBSD 9 amd64, within I create some jails, the ones contain services like mysql, email, and some others ldap. With FreeBSD 7 and 8 I didn't notice this behavior but with FreeBSD 9 something is not working well. I did a clean installation of FreeBSD 9 and root filesystem is using ZFS. Attached is an image hoping some one can give me a hint of what to check or any kind of advice. reboot capture screen image

• Computer hanged in the middle of bios flashing process

  - by Stalker

  I have a laptop: Toshiba Satellite c660-17j, today I decided to update BIOS. I've downloaded bios updater from manufacturer's web site, and in the middle of flashing process computer hanged. I was waiting more than 30 minutes, but nothing was changed on the screen, i've tryed to PRESS MORE BUTTONS, but there were no reactions, so i've turned it off by removing battery (all other methods failed, even pressing power button for ~10 secs). After that computer can't start. I understand, that there's MESS in BIOS chip, and it's possible to re-flash it with hardware programmer, but I don't have it. I remember, that on some PCs (even on my eeepc) there was possibility to re-flash bios by inserting usb flash-disk (with .dat file on it, which contained BIOS), and power on PC, while holding some keys combination, then PC was switching to BIOS programming mode and re-flashed BIOS, after that it was possible to boot up normaly. Is there a way to recover computer without hardware programming BIOS chip? p.s. sorry for my english.

• What's a good way to check that a player has clicked on an object in a 3D game?

  - by imja

  I'm programming a 3D game (using C++ and OpenGL), and I have a few 3D objects in the scene, we can say they are boxes for this example. I want to let the player click on those boxes to select them (ie. they might change color) with the typical restriction like if more than one box is located where the user clicked, only the one closest to the camera would get selected. What would be the best way to do this? The fact that these objects go through several transforms before getting to window coordinates is what makes this a bit tricky. One approach I thought about was that if the player clicks on the screen, I could normalize the x,y coordinates of mouse click and then transform the bounding box coordinates of the objects into clip-space so that I could compare then to the normalized mouse coordinates. I guess I could then do some sort of ray-box collision test to see if any objects lie as the path of the mouse click. I'm afraid I might be over complicating it. Any better methods out there?

• Enabling GTX 570

  - by Silas

  Hello i just built up my new system: Asus Rock Z77 Extreme 4 Intel i7 3770k 16 Gb Corsair Ram Zotac Nvidia GTX 570 bequiet! 630W Power supply 120 GB SSD So after i installed UBUNTU 12.04 64 bit. It ran smoothly. I downloaded and installed all the recommended updates. After checking the Sytem details the GTX 570 didnt show up as graphics unit. so i figured i needed to download the drivers. So i did but being a complete newbie to linux i didnt succeed in installing them. (I think) Anyway after several tries and errors i shut down the PC and restarted it. Resultung in do Signal to my screen after trying to reboot and all the monitor outs with no result i took out the graphic card and now it boots normally but after booting it says there is a problem with the system the graphics cant be recognized something something. So Question A: What do i do? I Like linux but the arbitrarity of the Errors that occur without any changes to the system scare me. Question B: Is there A beginners guide to Ubuntu where i could start from scratch because i really want this to work? Question C: Now that the System is (suddently) showing these graphic errors So far without visible consequence despite the error message. should i reinstall the GPU and give the driver installation another try or the other way around? Ill be very grateful for any help. Thank you in advance!

• Java game design question (graphical objects)

  - by vemalsar

  Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

• Can't set correct desktop resolution on Windows 7 after playing Mirror's Edge

  - by DeadMG

  Ever since I launched Mirror's Edge, my entire system seems to think that my monitor is 1600x1200, when actually it's 1920x1080. The game would only go up to 1600x1200, Windows will only go up to 1600x1200, and even my video drivers will only go up that high. The monitor isn't even that aspect ratio. I've rebooted the system to no effect, and installed the latest graphics drivers for my Radeon 5770, unplugged it and re-plugged it, etc. My secondary screen is still working perfectly correctly. Any suggestions?

• OEM Windows 8 Downgrade to Windows 7

  - by user1873048

  I recently Purchased an ASUS K55A As you may know, all Windows 8 machines come with a BIOS that contains 'Secure Boot'. This basically makes sure that the BIOS won't load anything other than the Windows 8 OEM bloatware version that comes with new Laptops. However the Asus Bios allows for me to disable the secure boot, and therefore I should be able to revert to Windows 7, Linux, etc. Drivers may or may not be supported. When I put my MINT LINUX boot disc in CD-R Drive and try to boot from ISO, nothing happens. There isn't even a boot priority list in this BIOS... I can provide screen shots later. It just says WINDOWS 8 Bootloader and also on the other tab it says WINDOWS 8 BOOT OVERRIDE Has anybody purchased a windows 8 machine and successfully loaded windows 7 or Linux?

• Display glitches running ATI propietary driver under Ubuntu 12.10

  - by crystallero

  I have a lot of problems with the Ati propietary driver (fglrx). I have an iMac (mid 2011) with a Radeon HD 6900M [1002:6720]. I did not have any problem under Ubuntu 12.04, but since I updated to 12.10, I get some annoying graphic corruption. The worst one is that sometimes the screen does not update with the new information. It happens a lot when I change between tabs in Chrome or Sublime Text. It usually gets updated when I scroll the page. Sometimes, when I type, I have to wait a little bit to view the new characters. And I get trails when I move windows too (like a part of the window). After a while, the trail disappears. I tried to install fglrx, fglrx-updates and the new beta driver downloaded from Ati (12.11 Beta 11/16/2012), with no luck. It happens the same with all of them. I tried to mess with Compiz config, but it didn't fix anything. The open source driver does not suffer this problem, but I need the performance of the propietary driver . Do you have any clue? Thanks.

• New Windows 7 Install Crashing

  - by bobber205

  One big reboot crash and one smaller crash already, 15 minutes in. Did a basic install of Windows 7, installed Chrome and Firefox. I had just finished loading up my gmail account in Chrome/Firefox to show the speed difference and we'd thought it would be hilarious to see how slow IE8 was. :P Just about as IE8 was done opening, the computer's screen goes black. After a restart and a couple minutes, Explorer crashes as well. What is going on? This install is only 15-20 minutes old. :P

• Crash when trying to detect touch

  - by iQue

  I've got a character in a 2D game using surfaceView that I want to be able to move using a button (eventually a joystick), but my game crashes as soon as I try to move my sprite. This is my onTouch-method for my steering button: public void handleActionDown(int eventX, int eventY) { if (eventX >= (x - bitmap.getWidth() / 2) && (eventX <= (x + bitmap.getWidth()/2))) { if (eventY >= (y - bitmap.getHeight() / 2) && (y <= (y + bitmap.getHeight() / 2))) { setTouched(true); } else { setTouched(false); } } else { setTouched(false); } And if I try to put this in my update-method: public void update() { x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } The sprite moves on its own just fine, but as soon as I add: public void update() { if(steering.isTouched()){ x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } the game crashes. Does anyone know why this is or how to fix it? I cannot figure it out. I'm using MotionEvent.ACTION_DOWN to check if the user if pressing the screen.

• Partition table damaged

  - by emaster70

  Hello, I'm currently in a terrible situation with my hdd: I was trying to install an OS side by side with my windows 7 x64 and I used the Paragon Partition Manager feature made for that. It disabled/hid/(damaged?) one of my partitions and now I can no longer access it. The partition, unfortunately, contains data I need to access urgently and I've got no backup. To complicate things even further I don't have another PC (I'm writing this msg from my iphone) and all I can rely on is a backtrac 4 disk (wkn't connect to my wifi, gets stuck obtaining IP address) and. Windows 7 x64 disk. Booting into windows fails with the pc hanging on the starting windows screen. Safe mode won't work either. Is there anything I can do? Here's the layout of the disk: Recovery partition Win partition Unallocated space (it's supposed to be my data partition) Other os partition (don't care about that, the installation of the other OS failed) Please help me, I'm desperate.

• RocketRaid gives me stuttering computer

  - by Dan

  I have a SANS DIGITAL TowerRAID TR8M-BP (with the RocketRaid 622 raid device) with 5 x SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM SATA 3.0Gb/s harddrives in a raid 5. It connects via 2-esata cables. My drivers are up to date. When I'm writing data to the drives my computer stutters (meaning freezes for a 1/2 second every 2 seconds or so). My screen freezes, my music goes into a loop, its really annoying. I get the same thing in windows 7 as I do in linux. The only difference is it seems to happen less in linux, but occassionally linux will crash (I've never had linux crash for any other reason, so I'm assuming they have poor linux drivers and kernal mod). Any tips for how to deal with this? Thanks

• Isn't Java a quite good choice for desktop applications?

  - by tactoth

  At present most applications are still developed with C++, painfully. Lack of portability, in compatible libraries, memory leaks, slow compilation, and poor productivity. Even if you pick only a single from these shortages, it's still a big headache. However the surprising truth is that C++ remains the first choice for desktop applications. Compared to C++ Java has lots of advantages. The success in server side development shows that the language itself is good, Swing is also thought to be as programmer friendly as the highly recognized QT framework (No, never say even a single word about MFC!). All the disadvantages of C++ listed above has a solution in Java. "Performance!", Well that might still be the problem but to my experience it's a slight problem. I'd been using Java to decode some screen video and generate key frames. The video has a duration of more than 1 hour. The time spent on an average machine is just 1 minute. With C++ I don't expect even faster speed. In recent days there are many news on the JIT performance improvements, that make us feel Java is gradually becoming very suitable for desktop development, without people realizing it. Isn't it?

• Make a animation path separated by clicks

  - by Tomáš Zato

  I have a long text on powerpoint slide. Instead of separating it on multiple slides, I made an animation that moves it up using animation path, so that text hidden at bottom appears while text on top goes off screen. However, I need more move animations to reaveal more text (the text takes more than 2 screens). This means, I need two (or more) animation paths (of the same length) and I want them to move obejct from position, where the last path has left it. Instead, multiple animations always operate with objects original position. That's useless. You can download test document, where I made an example of what I want: animation test.pptx

• How do I upgrade from ubuntu 9.10 to 12.10 on my Acer Aspire 3000

  - by 770

  I had my Acer Aspire 3000 as a dual boot XP/ubuntu 9.10 a couple years ago. I recently blew the dust of it and wanted to upgrade to 7/Ubuntu 12.10 so I began by formatting the Ubuntu side of the partition and apparently damaged the mbr as I could only get black screen with the error message: GRUB loading. error: no such partition grub rescue I then slaved the hdd to my win7 desktop and formatted the entire drive, both sides of the partition then reinstalled it in the Acer and tried to install win7. Upon starting the Acer I got the same error message: GRUB loading. error: no such partition grub rescue I then tried to reinstall Ubuntu 9.10 as I have an Ubuntu produced installation cd. Same result. Next day I received a new battery I had ordered for the Acer. I plugged it and the power supply in and hit the power button just to see if I at least could charge the battery but to my surprise Ubuntu 9.10 began to install, so I let it and it did. Now the hard drive shows 58 gb and 2.5gb partitions neither of which is formatted NTFS for/by windows. I am guessing that the GRUB/mbr was repaired somehow by the Ubuntu reinstallation. My question, should you choose to accept it; How can I get to my goal of dual boot win7/Ubuntu 12.10. I am a beginner and don't know much about linux or the terminology. Thank you for your thoughts and help.

• Control HelpButton, HelpRequested, HelpButtonClicked - Instant help for windows Dialog Form components

  Instant help for windows dialog components is a great feature and very much known since windows 98. but I saw many many people are not aware it and query on Google to get help, but “help button” for dialogs helps you or your customers to get the help instantly. Every dialog window has help icon if that dialog was coded to enable it. it really helps to know the functionality of the components quickly. For example I was trying to pint a document from acrobat reader and opened printer properties to print the content front and back of the paper. If you observe there is a help button before close button. To get help on options of “Print on Both Sides” you would need to click on help button first and then click on the area on which you want to see the help. above picture shows help text for the options of “Print on Both Sides”. If you would like to get the help using keyboard you can use F1 key. Help button can be displayed only if minimize button and maximize button both are not shown unless you want go with custom buttons. below is the way if you want to get Help button for windows forms.   In this sample demo I want to have a checkbox and need to show help when I click on F1 on check box. So I created a form which country check box and help label as show in adjacent picture. Below is the code for your code bind file. using System; using System.Windows.Forms; namespace WindowsFormsApplication1 {     public partial classForm1: Form    {         publicForm1()         {             InitializeComponent();         }         private void Form1_Load(objectsender, EventArgs e)         {             this.Text = "Help Button Demo Form";             lblHelp.Text = "Press F1 on any component to get Instant Help";             this.HelpButton = true;             this.MaximizeBox = false;             this.MinimizeBox = false;             chkCountry.Tag = "Check or Uncheck Coutry Check Box";             chkCountry.HelpRequested += newHelpEventHandler(chkCountry_HelpRequested);             chkCountry.MouseLeave += newEventHandler(chkCountry_MouseLeave);         }         void chkCountry_HelpRequested(objectsender, HelpEventArgs hlpevent)         {             ControlrequestingControl = (Control)sender;             lblHelp.Text = (string)requestingControl.Tag;             hlpevent.Handled = true;         }         void chkCountry_MouseLeave(objectsender, EventArgs e)         {             lblHelp.Text = "Press F1 on any component to get Instant Help";         }     } } In above code  “HelpRequested” is an event will be fired when you click on F1 on Country checkbox. I stored the help information in the checkbox property called “Tag”. You might also maintain a property file to keep help text for each component differently. If you click on F1 when focus is on main form instead on individual component then generally separate help window opens. This can be done using the event “Form.HelpRequested” to open help windows as in below code. this.HelpRequested += newHelpEventHandler(Form1_HelpRequested); voidForm1_HelpRequested(objectsender, HelpEventArgs hlpevent) {     frmHelp.Show(); } span.fullpost {display:none;}

• 2d game view camera zoom, rotation & offset using 'Filter' / 'Shader' processing?

  - by Arthur Wulf White

  I wish to add the ability to zoom-in, zoom-out, rotate and move the view in a top-down view over a collection of points and lines in a large 2d map. I split the map into a grid so I only need to render the points that are 'near' the camera. My question is, how do I render a point A(Xp,Yp) assuming the following details: Offset of the camera pov from the origin of the map is: Xc, Yc Meaning the camera center is positioned on top of that point. If there's a point in Xc, Yc it is positioned in the center of the screen. The rotation angle is: alpha The scale is: S Read my answer first. I am thinking there is more optimized solution, thanks. My question is how to include the following improvement: I read in the AS3 Bible book that: In regards to ShaderInput, You can use these methods to coerce Pixel Bender to crunch huge sets of data masquerading as images, without doing too much work on the ActionScript side to make them look like images. Meaning if I am performing the same linear function on a lot of items, I can do it all at once if I use Shaders correctly and save processing time. Does anyone know how that is accomplished? Here is a sample of what I mean: http://wonderfl.net/c/eFp0/
