  • Eclipse Plugin: Enablement of an Action based on the current selection - before the

    - by Itay
    Here's my problem: I am using the org.eclipse.ui.popupMenus extension point for adding a sub-menu whose Action that is bounded to the following class: public class MyAction implements IObjectActionDelegate { private Logic logic = Logic.getInstance(); // Singleton public void setActivePart(IAction a, IWorkbenchPart targetPart) { // Nothing here } public void run(IAction a) { // Do something... } public void selectionChanged(IAction a, ISelection s) { a.setEnabled(logic.isEnabled(s)); } } This action is working correctly in most cases (including the call a.setEnabled() in selectionChanged()). My problem at the very first time my action is being invoked. The selectionChanged method is called only after the menu item has been displayed (and not when the user has made the selection) which means that the call to a.setEnabled() will have no affect. Any ideas on how to make my action receive selectionChanged() notifications even before the fist time it is being invoked?

  • Design best practice - best way to handle user selection

    - by user1457227
    I'm an experienced developer (WPF) moving over to Android development. My question: an app I am developing allows the user to browse their local storage (such as SDCARD) and select a file. Now, should I simply create a new Activity (after the user has made a selection) to handle what I want to have the app do with that chosen file, -or- is the better approach to pass the path/name of the selected file back to the main Activity and let IT launch the next Activity? In other words, is the better practice to have the main Activity launch other (support) activities, or is it perfectly ok and normal to have one activity chain to another and on and on? Thanks!

  • MonthCalendar control selection range with EnableVisualStyles?

    - by warren_s
    I'm using the MonthCalendar control and want to programmatically select a date range. When I do so the control doesn't paint properly if Application.EnableVisualStyles() has been called. This is a known issue according to MSDN. Using the MonthCalendar with visual styles enabled will cause a selection range for the MonthCalendar control to not paint correctly (from: http://msdn.microsoft.com/en-us/library/system.windows.forms.monthcalendar.aspx) Is there really no fix for this other than not calling EnableVisualStyles? This seems to make that particular control entirely useless for a range of applications and a rather glaring oversight from my perspective.

  • On what should i not be pennywise buying a machine for SqlServer 2008?

    - by Michel
    Hi, i'm going to do a project for a client and i'll be hosting the database server myself. Normally it would be on my dev machine, but there will also be data pushed into it during developing and testing, so i would like to setup a dedicated test sql server. But, as you might guess, i can't afford to go to Dell and buy one mega 16 core 16 GIG 10 TB raid 5 machine (wow, that sounds cool) So i have to save the money somewhere... the hardware only has to live for a year (longer is nice of course), and the sql server won't be hit too hard: i guess the average server will only see it as a cough once in a while. But i do want the machine to be a bit performant: if it does get some data, it must be a bit responsive. So my question is were can i leave out the expensive parts: is 2 GB enough, or must i take 4GB, is an average processor enough or should it be a top of the bill? Is Sql server a large resource user or is a simple desktop pc good enough? It wil run on win2008 by the way.

  • My computer freezes irregularly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. Please note that this question change with each things that i try. (For additional details) What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. Sometimes my G-15 LCD screen flickers and caracters gets caried around temporary under heavy load. Now, most of the times, the BIOS hard disks boot order gets reversed for some reason and I have to put it to the right one and save each times I boot. (Might be unrelated, not sure, but it first started yesterday) Sometimes the BIOS doesn't detect my 750GB hard drive plugged in SATA1. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 45-55. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu Ran 6 short different CPU stress test on Fedora 15 (Haven't found any complete stress testers for Linux) and it didn't crash. Changed the thermal paste to some Artic Silver 5 for my CPU and stress tested the CPU, temperature was at 50 idle, then 64 highest and slowly went down to 62 during the test. Ran some stress testing with a temporary graphic card and it went ok. Ran furmark stress test with my original graphic card and it freezed again. GPU had a temp of 74C, a CPU temp of 58C and a mobo temp of 40C or 45C (Dunno which one it is from SpeedFan). Ran a furmark stress test and a CPU stress test at the same time, results: http://pastebin.com/2t6PLpdJ I have been using my computer without stressing it for about 2 hours now and no crashes yet. I also have disabled the AMD Cool'n'quiet function on the BIOS for a more regular power to the CPU. When I ran Furmark without C'n'q my computer didn't freeze but I had a "Driver Kernel Error" that have recovered (And Furmark crashed) all that while running a CPU stress test. The computer eventually frozed without me being at it, but this time my screen just went on sleep and I couldn't wake it. Using the stability tester in nTune my computer freezed again (In the same manner as before). I notived that Speedfan gives me a -12V of -16.97V and a -5V of -8.78V. I wonder if these numbers are reliable and if they are good or bad. I have swapped my G-15 with another basic USB keyboard (HP) and I have ran furmark for about 10 minutes with a CPU stability test running each 60 seconds for 30 seconds and my computer haven't crashed yet. Ran some more extended tests without my G-15 and it freezed like it usually do. Removed the nForce Hard disk controler. Disabled command queuing in the NVIDIA nForce SATA Controller for both port 0 and port 1 (Errors from the logs) Used CPUID HwMonitor, here are the voltages: http://pastebin.com/dfM7p4jV Changed some configurations in the motherboard BIOS: Disabled PEG Link Mode, Changed AI Tuning to Standard, Disabled the 1394 Controller, Disabled HD Audio, Disabled JMicron RAID controller and Disabled SATA Raid. When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) When my Graphic card and my CPU are stressed. Sometimes when my Graphic card is stressed. Never happenned while stressing only the CPU. Sometimes when my CPU is stressed. Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) Event logs (Warnings, errors and critical errors) for the last 24 hours: http://pastebin.com/Bvvk31T7 My current to-try list Reinstall the drivers and software 1 by 1 and do extensive stress testing between each. Update the BIOS firmware to the most recent stable one. Change my motherboard. Status updates Keeping only the last 3 (28/06 04pm) More stress testing and still pass the tests. (28/06 03pm) Been stress testing for 10 minute straight now and 5 minutes with both CPU and GPU being stressed at the same time. (28/06 03pm) Stress-testing right now, so far no problems. A little hope Tests with Furmark and Prime95. Testing Windows bare-bone: 30 Minutes stress, no freeze. Installing an Anti-virus and some software, restarting computer. Testing with Anti-virus and some software (No drivers installed): 30 Minutes stress, no freeze. Installing audio drivers, restarting computer. Testing with the audio drivers: 30 Minutes stress, no freeze. Installing the latest graphic drivers from EVGA's website (without 3d vision since I don't use it), restarting computer. Testing with the graphic drivers: 30 Minutes stress, no freeze. Configuring Windows to my liking and installing more softwares. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

  • PC: Quick Freeze, then BSOD, then forced reboot, then freezes again

    - by cr0z3r
    Lately I have been experiencing a weird issue. My PC will hang for a second and then BSOD - it stays there, so I have to reboot. Once Windows starts again and I'm logged in, after 1-10min it freezes again, this time without BSOD. RECAP: 1 second freeze BSOD, hangs there I have to force-reboot Once PC rebooted, I log back into Windows second freeze between a 1-10min range, no BSOD (alternatively, I get a freeze with a constant sound/noise, no BSOD) I contacted my PC provider, who told me my graphics-card might be flawed (Quadro 4000), so I used a Quadro 2000 that they lend me. The issue still occurred. The issue now seemed to belong to a flawed RAM module. Following my provider's steps, I removed all but the first from the left column and kept using my PC for a week or so without any issues. I then added the bottom-right module, and so on, until all modules were back inside - I had no problems. Now it seemed that a simple take-out-put-back-in of the RAM modules had fixed the issue. However, after a few months, the issue was back. I redid all the RAM-swapping I had done before, and concluded that the lower-right module was flawed. My provider changed it for another, and everything was great until now. My PC froze again for barely a second, hanged on a BSOD, I rebooted it, logged-in to Windows to get a freeze (without BSOD or reboot) 40 seconds later. Something worth noting, is that every time I reboot after the BSOD, it is something within Chrome that freezes my PC (e.g. this time I clicked the "restore" button as Chrome mentioned it had exited unexpectedly - from the previous freeze obviously - and it instantly froze). Finally, the Event Viewer lists 2 critical events in the past hour as "ID: 41, Type: Kernel-Power". PC-Specs: http://i.imgur.com/VZpbr.jpg Previous Dump-files: https://dl.dropbox.com/u/716600/DumpFiles_08_2012.zip I would like to thank anybody in advance for your help. You're great. UPDATE 1: I realized that I did not mention an awkward fact about this issue. After I have gotten the 1-sec freeze followed by a BSOD, after I rebooted because the BSOD hanged, and after I logged back in to get another (this time, eternal) freeze and rebooted once again, the PC does not boot back up. The power-light is on, but my monitor says "no signal", as if the PC wouldn't really be turned on. This truly seems a like a power-related issue, doesn't it? UPDATE 2: I just got a freeze, but without BSOD. My screen froze (while on Chrome, which is starting to seem suspicious to me) with an ongoing sound/noise. I had to force-reboot my PC. I would say this is a graphics-card issue, but this issue also happened when I was using the Quadro 2000 from my provider. UPDATE 3: I just got a BSOD while trying to render something (quite heavy, actually) in 3ds Max 2012. I left the BSOD "running", as it said it was writing dump files to disk. However, the percentage number stayed at 0, so after 15 minutes I force-rebooted. I then used the software WhoCrashed (thank you Dave) which reported the following from the C:\Windows\Memory.dmp file: On Thu 22.11.2012 22:13:45 GMT your computer crashed crash dump file: C:\Windows\memory.dmp uptime: 01:05:27 This was probably caused by the following module: Unknown () Bugcheck code: 0x124 (0x0, 0xFFFFFA80275AC028, 0xF200001F, 0x100B2) Error: WHEA_UNCORRECTABLE_ERROR Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA). This is likely to be caused by a hardware problem problem. This problem might be caused by a thermal issue. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: Unknown . Google query: Unknown WHEA_UNCORRECTABLE_ERROR

  • Is it necessary to burn-in RAM for server-class systems?

    - by ewwhite
    When using server-class systems with ECC RAM, is it necessary or even useful to burn-in the memory DIMMs prior to deployment? I've encountered an environment where all server RAM is placed through a lengthy multi-day burn-in/stress-tesing process. This has delayed system deployments on occasion and adds an extra step to the hardware lead-time. The server hardware is primarily Supermicro, so the RAM is sourced from a variety of vendors; not directly from the manufacturer like a Dell Poweredge or HP ProLiant. Is this process useful? In my past experience, I simply used vendor RAM out of the box. Isn't that what the POST memory tests are for? I've encountered and responded to ECC errors long before a DIMM actually failed. The ECC thresholds were usually the trigger for warranty placement. Do you burn your RAM in? If so, what method do you use to perform the tests? Has the burn-in process resulted in any additional platform stability? Has it identified any pre-deployment problems?

  • Red Hat 5.3 on HP Proliant DL380 G5 and failed drive on RAID controller

    - by thinkdreams
    I have a development ERP server here in my office that I assist with support on, and originally the DBA requested a single drive setup for some of the drives on the server. Thus the hardware RAID controller (an HP embedded controller) looks like: c0d0 (2 drive) RAID-1 c0d1 (2 drive) RAID-1 c0d2 (1 drive) No RAID <-- Failed c0d3 (1 drive) No RAID c0d4 (1 drive) No RAID c0d5 (1 drive) No RAID c0d2 has failed. I replaced the drive immediately with a spare using the hot-swap, but the c0d2 continues to mark itself as failed, even when I umount the partition. I'm loathe to reboot the server since I'm concerned about the server coming back up in rescue mode but I'm afraid that's the only way to get the system to re-read the drive. I assumed there was some sort of auto-detection routine for this, but I haven't been able to figure out the proper procedure. I have installed the HP ACU CLI utilties, so I can see the hardware RAID setup. I'd really like to find out what the proper procedure should have been, where I went wrong, and how to correct it now. Obviously this goes without saying I should NOT have listened to the DBA and set the drives up as RAID-1 throughout as was my first instinct. He wasn't worried about data loss, but it sure would have been easier to replace the failed drive. :)

  • Acer Aspire one is falling apart on Ubuntu

    - by Narcolapser
    Question: How do I have my netbook detect and install hardware? Info: I have an Acer Aspire One, it came with windows XP and I loaded it with Win7. I decided I wanted to change to Ubuntu so I tried Ubuntu netbook remix, which failed horribly, and so after attempting 3 or so other OS's I ended with Ubuntu Desktop 9.10. Which worked fine for a while, but there were some minor issues so I asked a question about it here and decided to change my OS again. This last weekend I tried mandriva like that guy in my other question suggested, no success. when I had though my netbook lost the ability to use it's touch pad, I didn't think much of it, just thought it must be a driver or something. But When Mandriva failed, and I also while I was at it tried Damn small linux and Debian, which both failed to, I decided to switch back to Ubuntu Desktop(some where in here my keyboard stopped working for one attempt to). But first I gave the netbook remix one more try. it worked this time, with the exception of it didn't have any networking. I thought it was a driver issue again and finished the weekend with ubuntu desktop 9.10 again. But now things get really crazy. it doesn't know it has a wireless card or an ethernet card. It doesn't know my phone is connected trying to provide wireless broadband either. I'm clueless on what could be the problem. And with only a minimal amount of experience with Ubuntu can't navigate the entire interface with only my keyboard(it doesn't detect a USB mouse when I plug it in, it had when I installed it. in fact the network interfaces were working just fine when I live boot ubuntu to installed it). Even so, I don't know where to go or what to do to make it recognize it's hardware. I'm in a dire situation, any help is welcome.

  • hard drive recognized by bios but not by windows

    - by tehgeekmeister
    I'm adding a new hard drive (A seagate ST31000340NS; I had links in here but I don't have enough reputation to post them. Interestingly, the bios recognizes it as a ST31000340AS, but it was bought as the other number...) to a friend's hp pavilion d4650e (mobo specs; google the model if you want the rest of the info, can't do more than one link.). Have had a hell of a time with it. Finally figured out that the hard drive needed a jumper set to limit the speed to 1.5gbps so the mobo would recognize it, and the bios DOES recognize it now. But not windows (using windows 7), using add new hardware or diskmgmt.msc. According to my friend, who was at the computer when it first booted after adding the jumper, a new hardware found dealio popped up saying something about raid, but I can't provide more info then that since I didn't see it. Ubuntu livecd recognized the drive before we changed the jumper. Haven't checked since then. XP didn't recognize it, that's the OS we started with. Upgraded to 7 hoping it might fix the problem. The only other info I can think of that might be immediately relevant is that the drive is plugged into the fifth sata channel, and the first channel is empty. Is this a problem? I assume not, because the two other drives (in a raid 0) and the cd and dvd drives are also on channels past the first one, and are recognized. Ask questions and I'll update with info!

  • Constant crashes in windows 7 64bit when playing games

    - by yx
    I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred.

A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

  • Investigating a potential CPU failure

    - by Jernej
    On a Ubuntu server that I am using for computations I have recently observed that some CPU extensive programs (GUROBI,CPLEX) often segfault. Being in correspondence with tech support of the respective programs I was suggested that it may be a hardware issue. The administrator of the server performed a detailed memtest and it turned out that the RAM modules appear to be fine. Hence I've used the tool mprime to test the CPU and the following two lines appear multiple times durring the execution of the stress tests: [Worker #4 Oct 18 18:47] FATAL ERROR: Rounding was 0.498046875, expected less than 0.4 [Worker #4 Oct 18 18:47] Hardware failure detected, consult stress.txt file. The stress.txt file in itself is not very verbose about what could be the cause of this error so I would like to ask whether anyone here happens to know what could be the cause of this issue? Is there some other test I could perform to nail the problem even further? The temperature of the system (and all cores) was fine during the entire stress test (+69.0°C (high = +80.0°C, crit = +98.0°C)) the CPU in question is a Intel Core i7-2600K CPU @ 3.40GHz and is not overclocked or modified in any way. Also what is interesting that if I run mprime to only stress the CPU all tests pass fine. The error is only triggered when I let mprime stress the CPU+RAM.

  • vyatta Server Reboots by itself

    - by Fernando
    I have an issue regarding some hardware, maybe you can help me. First, I set up a Supermicro Superserver SYS-5016I-NTF with a Intel Xeon X3470 and 4 GB of Ram with a Hotlava Card Tambora 64G4 with Intel Chipset 82599EB and 4x10G SPF+ ports. Installed Vyatta community edition 6.3. I used it as router making BGP connections with 2 operators. No load at all, temp ranges normal. But the issue is that it reboots by itself in a ramdom way. Not very often, once every few days. But it is unacceptable for production purposes. So I try to test on different hardware, and installed Vyatta community edition 6.3 on a Dell PowerEdge 2950, with Xeon(R) E5345 @ 2.33GHz and 4 GB of Ram. Same Vyatta configuration as Supermicro Server. With same hotlava Card model ( I bought two of them ) Well I have reboots with this equipment as well. Same frecuency as above. I have checked syslog no strange logs until boot process starts to be logged. So it seems server reboot suddenly. I have installed latest driver for the chipset of the Hotlava card. Servers are placed in a datacenter with UPS So finally two things in common in both servers: Hotlava Card. Someone with issues with this card, or the chipset?? Could be it this card?? Vyatta 6.3 community edition. I don't thing is the problem. Is a regular Debian with packages to glue together different services. Or maybe is something I am missing. Andy ideas, suggestions?? Thank you very much... Fernando

  • How far should we take the N+N redundancy craziness ?

    - by Brann
    The industry standard when it comes from redundancy is quite high, to say the least. To illustrate my point, here is my current setup (I'm running a financial service). Each server has a RAID array in case something goes wrong on one hard drive .... and in case something goes wrong on the server, it's mirrored by another spare identical server ... and both server cannot go down at the same time, because I've got redundant power, and redundant network connectivity, etc ... and my hosting center itself has dual electricity connections to two different energy providers, and redundant network connectivity, and redundant toilets in case the two security guards (sorry, four) needs to use it at the same time ... and in case something goes wrong anyway (a nuclear nuke? can't think of anything else), I've got another identical hosting facility in another country with the exact same setup. Cost of reputational damage if down = very high Probability of a hardware failure with my setup : <<1% Probability of a hardware failure with a less paranoiac setup : <<1% ASWELL Probability of a software failure in our application code : 1% (if your software is never down because of bugs, then I suggest you doublecheck your reporting/monitoring system is not down. Even SQLServer - which is arguably developed and tested by clever people with a strong methodology - is sometimes down) In other words, I feel like I could host a cheap laptop in my mother's flat, and the human/software problems would still be my higher risk. Of course, there are other things to take into consideration such as : scalability data security the clients expectations that you meet the industry standard But still, hosting two servers in two different data centers (without extra spare servers, nor doubled network equipment apart from the one provided by my hosting facility) would provide me with the scalability and the physical security I need. I feel like we're reaching a point where redundancy is just a communcation tool. Honestly, what's the difference between a 99.999% uptime and a 99.9999% uptime when you know you'll be down 1% of the time because of software bugs ? How far do you push your redundancy crazyness ?

  • How do you notice that the batteries of you wireless mouse are dying out?

    I have a Logitech M705 wireless mouse. I'm first time using a wireless mouse, so I don't have much experience with the hardware features and behavior. It is rated that it runs for 3 years with the same batteries. I think this "3 year" rating is calculated for a very low usage and activity; like 2 hours a day. I'm using it for about 12 hours a day, so I expect it to run out of batteries in a much shorter time in my case. I have been using it for about half a year. Recently (for the last two weeks), it started to make some peculiar behavior when clicking and drafging objects. - When I click something, it sometimes double click it. - When I drag something from one place to another (or selecting some text), it sometimes drops the object in the halfway (when selecting text, the text which had selected up to that time becomes unselected and it starts to select the rest of the text from that moment), but it goes on being in the "left-button-pressed" state. It is like, the pressed button switches to "unpressed" state for a moment, then returns back to the "pressed" state. When one of these faults occur, it occurs several times sequentially. There is no problem in pointer movement, scrolling or right-clicking. Since the batteries last for a very long time for this device, I don't expect it to stop working in an instance. I expect it to give these kind of syndromes of a time period. My question is; Is this how batteries run out for a wireless mouse? Or, is this another kind of hardware/software problem?

  • cheap gigabit switch for small business

    - by neoice
    my friend's business is currently borrowing my Adtran 1224R and is very happy with it. it's configured with a few VLANs to segment customers, internal traffic and public wifi. port 1 is a "trunk" port to the router, a chunky Linux box with iptables+NAT. they push a lot of traffic over the LAN (data backups) and really need gigabit. besides, I'd like my Adtran back :P my goal is to find a cheap(ish) switch that can function as a drop-in replacement. it looks like VLAN trunking is actually part of the 802.1q spec, so anything with VLAN support should cover the current trunk-to-router setup. it's nice to have both a web interface and SSH, but I can configure it either way if needed. things like the Netgear GS724T have caught my eye, but it seems like none of the hardware in the $300-500 range have really solid reviews. I'm concerned that "cheaper" hardware might not work for a network full of power users. does anyone have a recommendation for the Netgear GS724T or a switch that will meet my needs?

  • C# WPF Paginator printer ignoring user's printer selection

    - by Anders
    I am using the following code in my project. The print dialog shows, but it always prints on the default printer regardless of the user's selection. I have read similar topics but none of them seem to use the SerializerWriterCollator. What is the problem? PrintQueue printQueue = LocalPrintServer.GetDefaultPrintQueue(); XpsDocumentWriter xpsWriter = PrintQueue.CreateXpsDocumentWriter(printQueue); SerializerWriterCollator batchPrinter = xpsWriter.CreateVisualsCollator(); var printDialog = new PrintDialog(); if (printDialog.ShowDialog() == true) { PrintTicket ticket = printDialog.PrintTicket; ticket.PageOrientation = PageOrientation.Landscape; var paginator1 = new PagePrinter(winchFlightsCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), winchFlights); var paginator2 = new PagePrinter(tugFlightCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), tugFlights); var paginator3 = new PagePrinter(selfFlightCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), selfFlights); batchPrinter.BeginBatchWrite(); for (int i = 0; i < paginator1.PageCount; i++) { batchPrinter.Write(paginator1.GetPage(i).Visual, ticket); } for (int i = 0; i < paginator2.PageCount; i++) { batchPrinter.Write(paginator2.GetPage(i).Visual, ticket); } for (int i = 0; i < paginator3.PageCount; i++) { batchPrinter.Write(paginator3.GetPage(i).Visual, ticket); } batchPrinter.EndBatchWrite(); } }

  • Row selection based on subtable data in MySQL

    - by Felthragar
    I've been struggling with this selection for a while now, I've been searching around StackOverflow and tried a bunch of stuff but nothing that helps me with my particular issue. Maybe I'm just missing something obvious. I have two tables: Measurements, MeasurementFlags "Measurements" contain measurements from a device, and each measurement can have properties/attributes attached to them (commonly known as "flags") to signify that the measurement in question is special in some way or another (for instance, one flag may signify a test or calibration measurement). Note: One record per flag! Right, so a record from the "Measurements" table can theoreticly have an unlimited amount of MeasurementFlags attached to it, or it can have none. Now, I need to select records from "Measurements", that have an attached "MeasurementFlag" valued "X", but it must also NOT have a flag valued "Y" attached to it. We're talking about a fairly large database with hundreds of millions of rows, which is why I'm trying to keep all of this logic within one query. Splitting it up would create too many queries, however if it's not possible to do in one query I guess I don't have a choise. Thanks in advance.

  • Style row banding and selection in tr:table using CSS

    - by Alex Larzelere
    I've got a tr:table that I need to style using CSS. All the normal style functions of a table are working, but row banding and row selection aren't coming up. When I view the rendered source, I'm not seeing a difference in the rows for an id or class to grab on to, and the official documentation doesn't have any attributes for declaring a style class for either. Is this possible and if so what do I need to do to get my CSS to grab onto it? <tr:table id="myTable" value="#{tableValues}" rowBandingInterval="1"> <tr:column> ##Stuff## </tr:column> <tr:column> ##Stuff## </tr:column> <tr:column> ##Stuff## </tr:column> </tr:table> Edit Let me try to clairfy what's happening. First, using the declaration above tells jsf to generate a table, and the attribute rowBandingInterval tells it to give each row alternating colors (If it was set to 2, then it would do 2 rows one color, 2 rows another, 2 rows the original, etc.) Once the page gets rendered into standard html, trinidad (and jsf) apply their own classes and IDs to the html. My normal procedure is to look at the rendered html, find the class that it is appling and add CSS rules for it. However in this case, no additional styles are added (nothing in the rendered html denotes one row to be different from another). So the question is, how do I tell trinidad to either give alternating rows and the user selected row different classes/IDs for me to grab on to with CSS?

  • How to manage a single-selection (exclusive) list?

    - by Andy
    I've got a detail view that consists of a table view with a few rows of data. I can fill the rows just fine, and moving back and forth from the parent view to the subview works too. This detail view should allow the user to select a single value, placing a checkmark accessory in the cell and then returning to the parent view (where the selected value becomes the cell.textLabel.text property of the cell from which the detail view was called). This all works as of right now. However, when the user taps the cell in the parent view to go back to the detail view (to change their selection), my checkmark has disappeared and I cannot for the life of me figure out how to make it stay. Here's my cellForRowAtIndexPath: method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; } NSString *labelText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumberLabel"]; cell.textLabel.text = labelText; NSString *currentLabel = [ruleBuilder.tableView cellForRowAtIndexPath:selectedIndexPath].textLabel.text; if (labelText == currentLabel) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } NSString *detailText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumber"]; cell.detailTextLabel.text = detailText; return cell; } I've checked out Apple's sample code for exclusive-list management in Table View Programming Guide, but the snippet seems incomplete, and I can't find the related code in Apple's sample code. This doesn't seem like it ought to be that hard to do.

  • Handling row selection from a simple grid using jquery and asp.net mvc

    - by Jonn
    Using a simple table and jquery, how would you manually handle selection using jquery? So far, I've managed to add a gridrowselected class on the tr when the click event is called so that I'll know which row is currently selected. But I don't know how to pass the selected data back to the controller (or at least an index I placed on the row). I tried something like this $(function() { $('#ProjectList .gridrow').click(function() { // Get row's index var projectId = $(this).find('input[name$=ProjectId]').val(); // Remove the input if it already exists var parentForm = $(this).parents('form'); parentForm.remove('input[name="selectedRows"][value="' + projectId + '"]'); // If it is selected, create the form. If it's not selected then the input just gets removed (the user must have clicked on it and deselected the row) if ($(this).hasClass('gridrow-selected') === true) { parentForm.append($('<input>', { type: "hidden", name: "selectedRows", value: projectId })); } }); }); which I'm expecting to create a hidden input so that when I post, selectedRows gets passed onto the controller. But all it does is create the input, but the data still doesn't get passed to the controller.

  • Exclude notes based on attribute wildcard in XSL node selection

    - by C A
    Using cruisecontrol for continuous integration, I have some annoyances with Weblogic Ant tasks and how they think that server debug information are warnings rather than debug, so are shown in my build report emails. The XML output from cruise is similar to: <cruisecontrol> <build> <target name="compile-xxx"> <task name="xxx" /> </target> <target name="xxx.weblogic"> <task name="wldeploy"> <message priority="warn">Message which isn't really a warning"</message> </task> </target> </build> </cruisecontrol> In the cruisecontrol XSL template the current selection for the task list is: <xsl:variable name="tasklist" select="/cruisecontrol/build//target/task"/> What I would like is something which selects the tasklist in the same way, but doesn't include any target nodes which have the attribute name="*weblogic" where * is a wildcard. I have tried <xsl:variable name="tasklist" select="/cruisecontrol/build//target[@name!='*weblogic']/task"/> but this doesn't seem to have worked. I'm not an expert with XSLT, and just want to get this fixed so I can carry on the real development of the project. Any help is much appreciated.
