  • C# Threading Background Process - Programming - How to?

    - by Magic
    Hello...I have been given the horrible task of doing this. Launch the website Take a screenshot Fill in the form details, click on Next Take a screenshot ... ... ... Rinse. Repeat. Now, with various combinations, this comes up to 300 screenshots. And I have to do this for 4 different browsers. Chrome, Firefox, IE 6 and IE 7. I cannot use tools which will capture the screenshot and store them, such as, SnagIT. I need to take a screenshot, copy it to a Word Document and take the second screenshot and take it to a Word Document. I thought, I will write a tiny utility which will help me do this. Here is the requirement spec that I put up for it - An executable which once launched seats itself in the System Tray. While it is active, all instances of Key Press (Print Scrn), it should write the contents to a Word Document as defined (either a default path or a user defined one). Save the document periodically. Now, my question is - if I am going to develop this using C# (Winforms application), how do I go about doing this. I can do a fair bit of C# programming and I am willing to learn. But I am not able to locate the references for how to do a background process so that it runs in the background. And while it runs, it has to capture the Print Scrn command. Can you folks point me to the right material where I can learn this? Theoretical references should suffice. But if there are practical references, then nothing like it. Thanks!

  • How to write code that communicates with an accelerator in the real address space (real mode)?

    - by ysap
    This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

  • Start a new project. Where is the inspiration ?

    - by Kakawait
    The question may seem strange at first glance ... And I may be alone in this situation. But currently I want to improve my skill through learning new framework. however, do a simple "HelloWorld" application does not satisfy me. I think a practical project is required to apprehend the basics of a framework. I know there is many scholar-like project like design a library manager or CMS. But I have recently planned to learn ~3 differents frameworks and I can't find any motivations through "unexciting" project. In the end I have not started any framework ... I'm aware of I do not develop the project of the year ... I'm just looking for something a bit exciting. I do not expect any project subject, anyway stimulation provided by a project is something subjective. But I want to know your inspiration ! (or method to learn framework ^^) I'm talking about web-dev framework but I'm open to any kind information ! Kind regards.

  • Circumventing a manual HTML login page for "unclassified" websites

    - by auramo
    The IT department just made my life a little bit harder again: they introduced a manual HTML login page for all websites they have not "classified". This means that all the applications which try to access unclassified websites for e.g. downloading plugins do not work. Examples: Eclipse plugin installation, Maven builds etc. What would be the easiest workaround for this? The best I've come up with is try to extend/customize Ruby's httpproxy.rb that comes with Webrick. I would automate the manual login process whenever that login response page is detected. This sounds quite painful, and I think there might/should be simpler options?

  • How to shutdown Windows 8 PC without using mouse?

    - by Gopinath
    Windows 8 sports a re-imagined desktop and tablet user interface with touch friendly Metro looks. One of the major changes in Windows 8 for a common users  is the lack of start menu, with which we got friended for more than a decade. On Windows 8 we would be missing it. As there is no start menu in Windows 8, the way you shutdown a Windows 8 computer is a bit different. To shutdown using Mouse, you need to hover on the top right edge of the screen to open the hidden menu,  go to "Settings"  tab -> "Power" -> Then choose for "Shut down", "Sleep" or "Restart".  That’s a lot of Mouse movement work and if you are a power user then you may not like to do that. How about shutting down the PC using Keyboard? Here are the two ways to shutdown the PC using keyboard Keyboard shortcuts With the help of keyboard shortcuts you can navigate to Power options of Windows 8. Press Win + C to bring the Settings Charm and use Arrows and Enter keys to navigate to access Shutdown menu. This is one of the easiest way to shutdown the PC without using Mouse. Run Command If you don’t like to go through the Setting menu, you can use the traditional Run commands. Press Win + R to open Run dialog and enter the command shutdown -s -t 0 to immediately shutdown the PC.

  • Choosing a Linux distribution

    - by Luke Puplett
    Dangerous territory with this question so please try to be impartial and instead focus on what to look for when choosing a Linux distribution. I'm completely new to Linux. I thought it'd never happen but I need to have a Linux box to play with and I have a spare fanless Atom PC (32-bit only). I'll be using the machine as a non-commercial hobby server, the trouble is, I don't even know how to compare Linux distributions and why people pick one over another. If anything, I want to have an easy install from USB stick. My question is: what do you look for when choosing a (free?) Linux distribution for a server? If you can, please explain what sorts of things actually differ between one and another without saying which you think is better, just the facts. The way I see it, Linux as a server is just an SSH console and I find it hard to imagine what could be different between one and another.

  • World Location issues with camera and particle

    - by Joe Weeks
    I have a bit of a strange question, I am adapting the existing code base including the tile engine as per the book: XNA 4.0 Game Development by example by Kurt Jaegers, particularly the aspect that I am working on is the part about the 2D platformer in the last couple of chapters. I am creating a platformer which has a scrolling screen (similar to an old school screen chase), I originally did not have any problems with this aspect as it is simply a case of updating the camera position on the X axis with game time, however I have since added a particle system to allow the players to fire weapons. This particle shot is updated via the world position, I have translated everything correctly in terms of the world position when the collisions are checked. The crux of the problem is that the collisions only work once the screen is static, whilst the camera is moving to follow the player, the collisions are offset and are hitting blocks that are no longer there. My collision for particles is as follows (There are two vertical and horizontal): protected override Vector2 horizontalCollisionTest(Vector2 moveAmount) { if (moveAmount.X == 0) return moveAmount; Rectangle afterMoveRect = CollisionRectangle; afterMoveRect.Offset((int)moveAmount.X, 0); Vector2 corner1, corner2; // new particle world alignment code. afterMoveRect = Camera.ScreenToWorld(afterMoveRect); // end. if (moveAmount.X < 0) { corner1 = new Vector2(afterMoveRect.Left, afterMoveRect.Top + 1); corner2 = new Vector2(afterMoveRect.Left, afterMoveRect.Bottom - 1); } else { corner1 = new Vector2(afterMoveRect.Right, afterMoveRect.Top + 1); corner2 = new Vector2(afterMoveRect.Right, afterMoveRect.Bottom - 1); } Vector2 mapCell1 = TileMap.GetCellByPixel(corner1); Vector2 mapCell2 = TileMap.GetCellByPixel(corner2); if (!TileMap.CellIsPassable(mapCell1) || !TileMap.CellIsPassable(mapCell2)) { moveAmount.X = 0; velocity.X = 0; } return moveAmount; } And the camera is pretty much the same as the one in the book... with this added (as an early test). public static void Update(GameTime gameTime) { position.X += 1; }

  • Conversion of DVC-PRO HD 1080, any free tool?

    - by Andrea Ambu
    Is there any free (as in beer, and if it's possible as in bird) tool to convert a dvd in the format DVC-PRO HD 1080 to a normal/standard dvd format so that I can play it on a normal DVD player? EDIT: I changed the wording a bit. We've a video in DVC-PRO HD 1080 but as far as I know it is a proprietary format. We'd like to create a standard dvd out of it. I'm not really in video encoding and dvd conversion. I thought I need to be more precise. VLC currently doesn't support DVC-PRO HD 1080.

  • Windows Proxy Server advice

    - by Scott
    I have a webserver that currently has about 10 IP addresses. I have various clients that require a proxy server to route their internal traffic through. The load is not that great, so I'd like to have this ONE server act as a proxy server for 10 different clients, each client having their own unique IP on the server. The hardware is already setup, but I'm wondering what software solutions you guys recommend? I've looked at WinGate, Squid-Proxy, etc...but am pretty green with this. Maybe there's even a way to have Windows do this natively? I'm running Windows Server 2008, 32 bit.

  • DEBIAN repository signing: a step-by-step guide.

    - by jldupont
    I've got many DEBIAN repository for my projects (e.g. EPAPI, erlang-dbus etc.). It seems that now Synaptic wants those to be signed for the packages to appear by default. For the DEBIAN kung-fu masters out there, please provide me with a step-by-step guide to achieving this, please. I've googled a lot but I am still a bit confused on the subject. update: I use a Launchpad PPA now... saves me from all this trouble.

  • Motherboard memory question

    - by JERiv
    I am currently drawing up specs on a new workstation for my office. I am considering the Asus P6X58D for a motherboard. This board's specs list it as supporting 24 gigs of memory. Suppose I were to use six four gig memory cards and then two video cards with 1 gig of memory apiece. Is the maximum supported memory similar to how 32 bit operating systems only have enough address space for 4 gigs of memory? Simply: Will the board post? If so, will the system be able to address all the memory, both the 24 gigs on the ddr3 bus and the 3 gigs on the graphics card?

  • estimating size of reply HTTP headers

    - by Guanidene
    I am trying to download a file via a basic socket connection, using a HTTP GET request. So, I have to specify how many bytes of data coming in I have to read from the socket. However, I am having trouble deciding the amount of data (say, in bytes) the server would reply back with. I know that there is a "Content-Length" field in the reply sent by server, but that gives me the size of the actual data (without the http headers). Is there a way to get the exact size of HTTP headers sent by the server or an estimation is required? (I am doing this for downloading on a mobile network, where every bit of data matters in terms of time and money, so I don't wish to make an unnecessary larger estimate of the header size.)

  • Differences between Cherry mechanical keyboard switches?

    - by TreyK
    I want a comfortable, responsive mechanical switch keyboard. My only concern about mechanical switch keyboards is the noise. Boards based off of the Cherry MX Blue seem to be the loudest, but apparently offer increased tactility. I don't mind a clicky noise (I would actually prefer a bit of noise), I just don't want anything overpowering. What are the different types of Cherry mechanical switches are out there, and what separates one from the other? Also, where would I be able to test one out?

  • Node.js apps and wordpress on the same vps

    - by Msencenb
    So currently my linode (ubuntu 11.10) serves up three node.js apps for me using connect's vhost middleware listening on port 80. Here is an example of how vhost sets up a domain: var portfolio = require('./bootstrap-portfolio/lib/app.js'); var server = express(); server.use(express.vhost('sencedev.com',portfolio)); server.use(express.vhost('www.sencedev.com',portfolio)); server.listen(80); However I would now like to add a wordpress installation to my vps as well. In the past for me this has meant a traditional apache installation; however I'm a bit unsure of how node.js + a different webserver (apache or nginx) should interact. Any thoughts on how I should approach hosting wordpress + node.js on the same box?

  • Rsync and Windows 7

    - by Nate
    Can someone give me any tips on setting up some sort of Rsync server/client on Windows 7 to run rsync between both my web hosting server, and a backup server that I have running Ubuntu? I've tried setting it up with this tutorial: http://www.youtube.com/watch?v=CvwdkZLNtnA Using copssh, and cwrsync. Ran into all sorts of troubles, including not being able to get cwrsync to run (it installs properly, but never starts up), and copssh not generating the keys at all. The guy was running Windows Server 2003, though, so I'm guessing the problems could just be because I'm running Windows 7. I've been trying to set it up with my Windows machine being the rsync server, and then Ubuntu and my webhosting VPS as the clients, but I realize it may be easier (and make more sense) to just setup the rsync server on Ubuntu, and then an rsync client on Windows 7? Can anyone point me in the right direction? I'm thinking of using this guide: http://www.gaztronics.net/rsync.php It seems a bit outdated, though.

  • Browser automatically refreshes and Home folder window opens

    - by Vikash
    I am facing a very strange problem. Out of the blue, my browser starts refreshing itself infinitely. My first guess was firefox is messing up. I installed chrome. But, it happens in chrome as well. Other than that, sometimes my home folder automatically opens and keep opening itself infinitely. My next guess was Mouse is faulty. Replace the mouse - but same things. This happens even if I remove my keyboard. What can be the reason? This started happening after I installed Ubuntu 10.10 few days back. Earlier on windows, everything was working fine. So, I am a bit skeptical to assume that this is a hardware fault. How to fix this problem? UPDATE: xev gives this kind of result: KeyPress event, serial 36, synthetic NO, window 0x4200001, root 0xb8, subw 0x0, time 29897358, (237,791), root:(1252,842), state 0x10, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XmbLookupString gives 1 bytes: (20) " " XFilterEvent returns: False KeyRelease event, serial 36, synthetic NO, window 0x4200001, root 0xb8, subw 0x0, time 29897603, (237,791), root:(1252,842), state 0x10, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XFilterEvent returns: False

  • Better way to go up/down slope based on yaw?

    - by CyanPrime
    Alright, so I got a bit of movement code and I'm thinking I'm going to need to manually input when to go up/down a slope. All I got to work with is the slope's normal, and vector, and My current and previous position, and my yaw. Is there a better way to rotate whether I go up or down the slope based on my yaw? Vector3f move = new Vector3f(0,0,0); move.x = (float)-Math.toDegrees(Math.cos(Math.toRadians(yaw))); move.z = (float)-Math.toDegrees(Math.sin(Math.toRadians(yaw))); move.normalise(); if(move.z < 0 && slopeNormal.z > 0 || move.z > 0 && slopeNormal.z < 0){ if(move.x < 0 && slopeNormal.x > 0 || move.x > 0 && slopeNormal.x < 0){ move.y += slopeVec.y; } } if(move.z > 0 && slopeNormal.z > 0 || move.z < 0 && slopeNormal.z < 0){ if(move.x > 0 && slopeNormal.x > 0 || move.x < 0 && slopeNormal.x < 0){ move.y -= slopeVec.y; } } move.scale(movementSpeed * delta); Vector3f.add(pos, move, pos);

  • Queueing up character actions

    - by TheBroodian
    I'm developing a 2D platformer with action-fighter elements. Currently things are working relatively smoothly but I'm having difficulty sorting something out. For the time, keeping my character's states and actions separated and preventing them from stepping on each others' toes is working out well and properly, but I would like to add a feature to my character to get him to behave a little bit more fluidly for the player. At the moment, he has numerous attacks and abilities that he can execute, all of them being executed with button presses. Here lies the problem: Being as everything is executed through button presses, while an action is in progress I flag the game to disregard further button presses until the action has completed. Therefore, consecutive actions cannot be performed until after the previous action has completed entirely. In runtime this behavior feels very icky, and very ungamelike. In games that rest most memorably at the forefront of my mind the player is able to execute button commands during the process of actions, and at the end of the current action, the following action is executed (seems like some sort of a queue system or something) Can anybody offer any guidance with this?

  • Looking at desktop virtualization, but some users need 3D support. Is HP Remote Graphics a viable solution?

    - by Ryan Thompson
    My company is looking at desktop virtualization, and are planning to move all of the desktop compute resources into the server room or data center, and provide users with thin clients for access. In most cases, a simple VNC or Remote Desktop solution is adequate, but some users are running visualizations that require 3D capability--something that VNC and Remote Desktop cannot support. Rather than making an exception and providing desktop machines for these users, complicating out rollout and future operations, we are considering adding servers with GPUs, and using HP's Remote Graphics to provide access from the thin client. The demo version appears to work acceptably, but there is a bit of a learning curve, it's not clear how well it would work for multiple simultaneous sessions, and it's not clear if it would be a good solution to apply to non-3D sessions. If possible, as with the hardware, we want to deploy a single software solution instead of a mishmash. If anyone has had experience managing a large installation of HP Remote Graphics, I would appreciate any feedback you can provide.

  • Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

    - by magneticMonster
    I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing. Why am I running out of lowmem and how do I increase it?

It's still "correcting" my texts. Searching for 'spelling correction' addons: The indicated option in the following borrowed screensnot does not exist on my PC. Is there any way of disabling it? I prefer a canonical solution if one is available. If not, I am also interested in registry hacks or other solutions.

  • Why can't I boot from portable HD?

    - by user11239
    I've been trying to get Ubuntu 10.04-LTS 32-bit desktop installed onto a 250GB FreeAgent Go drive from Seagate. I've been able to install onto a USB flash drive and boot successfully from this. I have installed Ubuntu onto the jump drive using Universal USB Installer, and this was a total success in terms of getting Ubuntu to run off a flash drive. I was unable to accomplish this with the portable HDD. I then, following instructions, attempted to install the OS onto the HDD once booted up from the flash drive. After installing the OS on the HDD, the computer would simply not load the OS when the HDD medium was selected for booting from. However, as there is no System-> Preferences-> Removable Drives and Media I could not complete this step. Is this vital? How do I do this under Ubuntu 10.04? I have formmated the MBR on the HDD and repeated the above, still with no success. I have also browsed some forums that mention there may be something related to spin-up speeds, but nothing explained in detail the issue or how to solve it, and I'm not familiar enough with system booting to understand if this could be an issue. Basically, what I'm trying to do is get Ubuntu to boot off the HDD, I've attempted several things, and the result is, after selecting the HDD from BIOS, the OS never starts booting (after waiting upwards of ten minutes). I just have a white cursor blinking. I can always get it to boot from the jump drive. Related question

  • Add "secure" in cookie by httpd server

    - by Abhishek
    How do I have to configure my httpd server to add "Secure" in the cookies? I tried the one in the below link, http://blog.modsecurity.org/2008/12/fixing-both-missing-httponly-and-secure-cookie-flags.html but this did not seem to be working. I inspected the cookie via firebug and found that the cookies have "HttpOnly" but not "Secure". I double checked the configurations and they the same as mentioned in the link. I also noticed that the server response time goes bit high when doing it by mod_security. Is there a better way to do it? Any ideas or pointers to configurations would be helpful

  • Putting our OLTP and OLAP services on the same cluster

    - by Dynamo
    We're currently in a bit of a debate about what to do with our scattered SQL environment. We are setting up a cluster for our data warehouses for sure and are now in the process of deciding if our OLTP databases should go on the same one. The cluster will be active/active with database services running on one node and reporting and analytical services on the other node. From a technical standpoint I don't see an issue here. With the services being run on different nodes they shouldn't compete too heavily for resources. The only physical resource that may be an issue would be the shared disk space. Our environment is also quite small. Our biggest OLAP database at the moment is only about 40GB and our OLTP are all under 10GB. I see a potential political issue here as different groups are involved but I'm just strictly wondering if there would be any major technical issues that could arise from this setup.
