  • Polling a web URL until event

    - by Jaxo
    I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

  • using same ids for many tags?

    - by gaurav rathor
    here is the example code that i was testing and i got confused that every one says that we can use or we should use only one time per id but i have testes using using it multiple times but its giving me the correct output. so what should i do. it is kinda working same like class for me in this example code: <html> <head> <style> #exampleID1 { background-color: blue; } #exampleID2 { text-transform: uppercase; } </style> </head> <body> <p id="exampleID1">This paragraph has an ID name of "exampleID1" and has a blue CSS defined background.</p> <p id="exampleID2">This paragraph has an ID name of "exampleID2" and has had its text transformed to uppercase letters.</p> <address id="exampleID1"> Written by W3Schools.com<br /> <a href="mailto:[email protected]">Email us</a><br /> Address: Box 564, Disneyland<br /> Phone: +12 34 56 78 </address> <blockquote id="exampleID1"> Here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation. </blockquote> </body> </html> please see the above code and answer me that why we should not use id selector two times in a page while its working fine.

  • JavaScript: supposed to execute functions sequentially, not actually doing so?

    - by AP257
    I'm seeing a lot of answers on StackOverflow that say that JavaScript executes code sequentially, but I can actually see my own JavaScript not doing so. From the following code: function centre_map(lat, lng, zoom_level) { alert('centre_map'); map = new GMap2(document.getElementById('map_canvas')); var latlng = new GLatLng(lat, lng); map.setCenter(latlng, zoom_level); } function add_markers_within_bounds() { alert('add_markers_within_bounds'); // add numerous BLUE markers within map bounds using MarkerClusterer } function add_marker(lat, lng, place_name, grid, county) { alert('add_marker'); // add one ordinary RED Google Maps marker } centre_map('{{lat}}', '{{lng}}', 12); add_markers_within_bounds('{{grid}}', '{{place_name}}'); add_marker('{{lat}}', '{{lng}}', '{{place_name}}', '{{grid}}', '{{county}}'); I get the following sequence of events: 'centre_map' alert 'add_markers_within_bounds' alert 'add_marker' alert individual RED marker appears on map (i.e. add_marker renders) multiple BLUE markers appear on map (i.e. add_markers_within_bounds renders) Why doesn't add_markers_within_bounds complete before add_marker gets under way: and how can I make it do so? I know that one way might be to call add_marker from within add_markers_within_bounds, but for various reasons I'd rather keep it as a separate function.

  • Usability for notification messages, colors

    - by metrobalderas
    In each app I develop, I like to add three types of messages: Green/blue for success messages Yellow for warnings Red for errors And perhaps, a neutral one for information, which is gray or blue if the success one is green. The success one is used for when an item is created or updated, the yellow one is when there's something wrong, but not we-are-going-to-die wrong and the red one is when something is blocked or we are going to die. However, there's one thing I can't figure out, when I delete an object, what kind of notification should I use? I think the success one is not because it is not expected, altough the deletion was successful, the user tends not to read the message, just to see the color. The red one might be, but it can be misunderstood (I tried to delete it but there was an error), the warning and the information one might be good choices, but I'm not really sure. Also, when you ask for confirmation about deleting something, the 'cancel' button should be green or red? I'm just curious how you guys handle this. Thanks.

  • Using Color.rgb() doesnt work for full 0...255 range

    - by superflyninja
    I'm writing an android game using opengl. I'm using: colour = Color.rgb(theR,theG,theB); (all ints) to store the color of a rectangle. Then I parse out the RGB to render the rectangle: colorR = Color.red(color); colorG = Color.green(color); colorB = Color.blue(color); For example for color 53,130,255 this should result in a blue but on my app it results in a white. If i use 1,1,1 i get white. If i use 0,0,0 i get black. If i use 0,1,0 I get green etc. So it looks like any value over one is treated as 1 and so i am not getting the full 0...255 range. I tried using Color.argb and color = Color.parseColor(theColor) where the Color is a string. I'm using this in an opengles app. I have a class to display a rectangle of color. This definitely works fine as the correct size rectangle is rendered, just not a color using values above 1. I also use textures and everything displays fine. any ideas? thanks a million

  • ARM TechCon 2013: Oracle, ARM expand collaboration on servers, Internet of Things

    - by Henrik Stahl
    If you have been following Java news, you are already aware of the fact that there has been a lot of investment in Java for ARM-based devices and servers over the last couple of years (news, more news, even more, and lots more). We have released Java ME Embedded binaries for ARM Cortex-M micro controllers, Java SE Embedded for ARM application processors, and a port of the Oracle JDK for ARM-based servers. We have been making Java available to the Beagleboard, Raspberry Pi and Lego Mindstorms/LeJOS communities and worked with them and the Java User Groups to evangelize Java as a great development environment for IoT devices. We have announced commercial relationships with Freescale, Qualcomm, Gemalto M2M, SIMCom to name a few. ARM and Freescale on their side have joined the JCP, recently been voted in as members of the Executive Committee, and have worked with Oracle to evangelize Java in their ecosystem. It is with this background, Nandini Ramani, Vice President, Java Platform at Oracle, announced a expanded collaboration with ARM in a TechCon 2013 keynote titled "Enabling Compelling Services for IoT". To summarize the announcement: ARM and Oracle will work together on interoperability between the ARM Sensinode communications stack (based on CoAP, DTLS and 6LoWPAN) and Oracle's Java ME, Java SE and middleware products. ARM will donate the Sensinode CoAP protocol engine to OpenJDK to stimulate broad adoption of the CoAP protocol, and work with Oracle to extend the relevant Java specifications with CoAP support. CoAP (Constrained Application Protocol) is an IETF specification that provides a low-bandwidth request/response protocol suitable for IoT applications. ARM will work with Oracle and Freescale to enable the mbed Hardware Abstraction Layer (HAL) to act as a portability layer for Java ME Embedded. Oracle will enable mbed as a tier one platform for Java ME Embedded. Over time, this effort will allow any mbed-enabled platforms (mostly based on Cortex-M microcontrollers) to work with off the shelf Java ME Embedded binaries, extending the reach of Java ME into IoT edge nodes. In Nandini's keynote, Oracle showed a roadmap to port the Oracle JDK for Linux on 64-bit ARMv8 servers in the 2015 time frame, preceded by an extended early access program. We expect this binary to have full feature parity with Oracle JDK on other platforms, and be available under the same royalty-free license. This effort has been going on for some time, but is now accelerated due to availability of hardware from Applied Micro. Oracle will be working with Applied Micro on the ARMv8 port, and on optimizing Java for their X-Gene products. Oracle and ARM will work closely on IoT architecture, and on evangelizing Java on ARM for both servers and IoT devices. These announcements reinforce Java's position as a first-class citizen in the ARM ecosystem, and signal a commitment from us to collaborate on driving standards and open ecosystem for the Internet of Things. If you are active in this area and not already in touch with us, or interested in learning more - please reach out to us!

  • BSOD in a Hyper-V Guest VM on install

    - by Greg Hurlman
    I've got Windows Server 2008 R2 running as a development environment, with Hyper-V hosting a few different VMs. I've created a new VM - 4GB of RAM, 2 virtual procs, legacy network adapter, removed the SCSI interface. I'm booting to an ISO image of the Windows Server 2008 R2 DVD, for OS install. The problem is, after the "Windows is loading files" screen, but before the Windows logo animation, I get a blue screen: BAD_SYSTEM_CONFIG_INFO yada yada yada *** STOP: 0x00000074 (etc, etc) I've used this same ISO several times to install to other VMs, no issue.

  • Radeon 68xx, 69xx cards and support for 10-bit color over displayport [closed]

    - by aCuria
    10-bit color, aka "Deep Color" is a scheme where 10 bits are used for each color channel. This makes for a 30 bit RGB implementation. IE: red: 10 bits green: 10 bits blue: 10 bits total: 30 bits For more information, please consult this link http://en.wikipedia.org/wiki/RGB_color_model#Beyond_truecolor:_deep_color Radeon 6000 series cards DO support deep color over HDMI, but HDMI also limits the output resolution to 1920x1200, which is not optimal. I want to know if Deep color is possible over display port with the HD6xxx series graphics cards.

  • Jerky transition after the login screen

    - by Bastien
    Hi, I have a clean install of Windows 7 Professional x64. After I type my password at the logon screen, the blue background is supposed to fade away smoothly and show the desktop, but on my machine the transition is jerky. I have an ATI graphics card and the Catalyst 10.2 drivers. What can I do to make the transition more smooth? Thanks!

  • Backing up my data causes my server to crash using Symantec Backup Exec 12, or How I Came to Loathe

    - by Kyle Noland
    I have a Dell PowerEdge 2850 running Windows Server 2003. It is the primary file server for one of my clients. I have another server also running Windows Server 2003 that acts as the core media server for Symantec Backup Exec 12. I recently upgraded from Backup Exec 11d to 12. This upgrade was necessary because we also just upgraded from Exchange 2003 to Exchange 2007. After the upgrade I had to push-install the new version 12 Backup Exec Remote Agents to each of the servers I am backing up (about 6 total). 5 of my servers are doing just fine, faithfully completing backups every night. My file server routinely crashes. Observations: When the server crashes, it does not blue screen, it just locks up completely. Even the mouse is unresponsive. If you leave the server locked up long enough, it will eventually reboot itself and hang on the Windows splash screen. There is absolutely zero useful Event Viewer evidence of a problem. The logs go from routine logging to an Unexplained Shutdown Event the next morning when I have to hard reset the server to get it to boot. 90% of the time the server does not boot cleanly, it hangs on the Windows splash screen. I don't have any light to shed here. When the server hangs all I can do is hard reset it and try again. Even after a successful boot and chkdsk /r operation, if you reboot the machine, you have a 90% chance it won't back up again cleanly. The back story: This server started crashing during nightly backups about a month ago. I tried everything I could think of to troubleshoot the problem and eventually had to give up because I could not keep coming to the office at 4 AM to try to get the server back online. One Friday I got lucky and the server stayed up for its entire full backup. I took this opportunity to restore the full backup to a temporary server I set up and switched all my users to the temporary. Then I reloaded the ailing file server. I kept all my users on the temporary file server for about 3 weeks. I installed the same Backup Exec Remote Agent and Trend Micro A/V client on the temporary server that I was using on the regular file server. During this time, I had absolutely no problems backing up the temporary server. I tested the reloaded file server extensively. I rebooted the server once an hour every day for 3 weeks trying to make it fail. It never did. I felt confident that the reload was the answer to my problems. I moved all of the data from the temporary server back to the regular server. I got 3 nightly backups out of it before it locked up again and started the familiar failure to boot cleanly behavior. This weekend I decided to monitor the file server through the entire backup job. I RDPd into the file server and also into the server running Backup Exec. On the file server I opened the Task Manager so I could view the processes and watch CPU and memory usage. Everything was running smoothly for about 60GB worth of backup. Then I noticed that the byte count of the backup job in Backup Exec had stopped progressing. I looked back over at my RDP session into the file server, and I was getting real time updates about CPU and memory usage still - both nearly 0%, which is unusual. Backups usually hover around 40% usage for the duration of the backup job. Let me reiterate this point: The screen was refreshing and I was getting real time Task Manager updates - until I clicked on the Start menu. The screen went black and the server locked up. In truth, I think the server had already locked up, the video card just hadn't figured it out yet. I went back into my bag of trick: driving to the office and hard reseting the server over and over again when it hangs up at the Windows splash screen. I did this for 2 hours without getting a successful boot. I started panicking because I did not have a decent backup to use to get everything back onto the working temporary file server. Once I exhausted everything I knew to do, I took a deep breath, booted to the Windows Server 2003 CD and performed a repair installation of Windows. The server came back up fine, with all of my data intact. I can now reboot the server at will and it will come back up cleanly. The problem is that I'm afraid as soon as I try to back that data up again I will back at square one. So let me sum things up: Here is what I've done so far to troubleshoot this server: Deleted and recreated the RAID 5 sets. Initialized the drives. Reloaded the server with a fresh Server 2003 install. Confirmed with Dell that I have installed the latest, Dell approved BIOS and NIC drivers. Uninstalled / reinstalled the Backup Exec Remote Agent. Uninstalled the Trend Micro A/V client. Configured the server not to reboot itself after a blue screen so I can see any stop error. I used to think the server was blue screening, but since I enabled this setting I now know that the server just completely locks up. Run chkdsk /r from the Windows Recovery Console. Several errors were found and corrected, but did not help my problem. Help confirm or deny the following assumptions: There are two problems at work here. Why the server is locking up in the first place, and why the server won't boot cleanly after a lockup. This is ultimately a software problem. The server works fine and can be rebooted cleanly all day long - until the first lockup - following a fresh OS load or even a Repair installation. This is not a problem with Backup Exec in general. All of my other servers back up just fine. For the record, all of the other servers run Server 2003, and some of them house more data than the file server in question here. Any help is appreciated. The irony is almost too much to bear. Backing up my data is what is jeopardizing it.

  • Windows 7 fails to install on KVM with qemu

    - by kief_morris
    I'm trying to install Windows 7 on a virtual machine on my 64 bit Ubuntu Karmic box. I get to the point of selecting my language settings and clicking 'install now', but a short while later I get a blue screen of death. I've tried a few variations, including using the 32 bit (fails very quickly). The virt-install command I've tried includes this: sudo virt-install --connect qemu:///system -n ksm-win7 -r 2048 \ --disk path=/home/kief/VM-Images/ksm-win7.qcow2,size=50 \ -c /var/Software/Windows7/Full/64bit/SW_DVD5_SA_Win_Ent_7_64BIT_English_Full_MLF_X15-70749.ISO \ --vnc --os-type windows --os-variant vista --hvm The limited info I could find suggested that 'vista' should work as the --os-variant, I haven't found any values specific to windows 7. Here's my blue screen: I've found very little by Googling, so I'm guessing this isn't a case of KVM simply not supporting Windows 7. Thanks for any help. Update: I have been able to successfully create a Windows 7 VM using the graphical "Virtual Machine Manager" app, although I don't really understand the cause of the problem with the VM created with virt-install. Comparing the configuration files under /etc/libvirt/qemu provides some clues, although I don't know enough to interpret them properly. The interesting differences in the two VM configurations are: --- win7-virt-install.xml +++ win7-vmm.xml -<domain type='qemu'> +<domain type='kvm'> @@ -21 +21 @@ - <emulator>/usr/bin/qemu-system-x86_64</emulator> + <emulator>/usr/bin/kvm</emulator> @@ -23 +23 @@ - <source file='/home/kief/VM-Images/ksm-win7.qcow2'/> + <source file='/var/lib/libvirt/images/ksm-win7x64.img'/> I'm not sure if this means the working VM is not using qemu at all, or if there is some other difference in the way it's used with kvm. Update2: So I've answered my own question (mostly) below. A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it. But at least it is possible to get it running on a KVM VM.

  • XP Pro SP3: DRIVER_IRQL_NOT_LESS_OR_EQUAL on hibernate

    - by Margaret
    Hey all I'm running XP Pro SP3 on a Late 2007-era 2.2Ghz Macbook. Unfortunately, it's recently started giving me a Blue Screen of Death when I try to hibernate it. It gives me the error "DRIVER_IRQL_NOT_LESS_OR_EQUAL", and at the bottom says that it's in "hiber_atapi.sys". Most of the Googling I've done thus far turns up things referring to Windows Server 2003, which is obviously less than useful. Anyone know any way to fix this short of a full re-install?

    I need to find all compressed files/folders regardless of file format on a Windows Server 2003 machine. Search options do not provide this capability. Is there a way to list/view all compressed files? Perhaps, this can be done by PowerShell using file/folder attributes and put into a txt file with file location. UPD: Under compressed files/folders - I mean files which appear in blue color in Explorer after changing file/folder attribute.
