  • Can you use a DVI-VGA Adapter on a monitor instead of a video card?

    - by Joel Coehoorn
    I suspect the answer to this is "no", but here goes: I have a monitor with inputs for DVI and VGA. I want to be able to share this display with two computers (one at a time, of course) that both have VGA only. I also have a DVI-VGA dongle that came with a video card that's in a different computer. Can I connect this dongle directly to the DVI port on the monitor so that I can connect both VGA computers? I'd rather not resort to a kvm.

  • Motherboard with embedded hdmi problems with Windows 8 Consumer Preview (64bit)

    - by duluca
    I'm specifically referring to GIGABYTE GA-E7AUM-DS2H LGA 775 NVIDIA GeForce 9400 HDMI Micro ATX with a Core 2 Duo chip. This computer is connected to a Sharp Aquous TV using HDMI. It all worked fine with Windows 7 64 bit. In Device Manager I see GeForce 9400 and have installed the latest NVidia drivers (295.73 WHQL). However, when I click on the change the screen resolution to 1920x1080, I see that Windows 8 thinks that it's using some other graphics card with Microsoft Basic Display Driver. This was made clear, when I tried to launch the NVidia tools and it claimed that the current monitor (in this case my TV) wasn't attached to the GeForce 9400 card. In Device Manager, there's a "Coprocessor" and "Unknown device" without drivers, but I've no idea what they are. I've run the original CD that the motherboard came with no success. Any ideas?

  • Is there a pure HTML5 emacs mode?

    - by Marcelo Santos
    Question http://stackoverflow.com/questions/1082474/authoring-html5-in-emacs talks about nxml-mode but, from what I read, that can only be used for XHTML5, I want to use emacs with HTML5 (no XML syntax). Is there any mode with auto-indentation, tag/attribute completion, etc.?

  • Using "margin: 0 auto;" in Internet Explorer 8

    - by stusmith
    I'm in the process of doing some advance IE8 testing, and it seems that the old technique of using "margin: 0 auto;" doesn't work in all cases in IE8. The following piece of HTML gives a centered button in FF3, Opera, Safari, Chrome, IE7, and IE8 compat, but NOT in IE8 standard: <div style="height: 500px; width: 500px; background-color: Yellow;"> <input type="submit" style="display: block; margin: 0 auto;" /> </div> (As a work-around I can add an explicit width to the button). So the question is: which browsers are correct? Or is this one of those cases where the behaviour is undefined? (My thinking is that all the browsers are incorrect - shouldn't the button be 100% width if it's "display: block"?) UPDATE: I'm being a dunce. Since input isn't a block-level element, I should have just contained it within a div with "text-align: center". Having said that, for curiosity's sake, I'd still like to know whether the button should or shouldn't be centered in the example above. FOR THE BOUNTY: I know I'm doing odd things in the example, and as I point out in the update, I should have just aligned it center. For the bounty, I'd like references to the specs that answer: If I set "display: block", should the button be width 100%? Or is this undefined? Since the display is block, should "margin: 0 auto;" center the button, or not, or undefined?

  • Recommendation for a Pagination procedure AJAX PHP

    - by Jamex
    Hi, I am not sure the correct terminology for the process that I am trying to describe. I don't even know which platform is underlying the technique. If you understand my description, please give the link to the site(s) and or the keyword name of the process. I think it is done by AJAX, but I am not certain. I use php as the backend code, I just need to find a way to dynamically display the results. Please give suggestions. I forgot the name of the sites that use this, and my link history expired. TIA Description: The page would have a search form and options. After the user submits, the search is initiated, and the results appear inside the dedicated result area. The page does not refresh, just the info inside the result area. The display area will show 20 (or whatever) results (lines). There will be next, and previous buttons. If you hit next, the next set of results will display. I am writing a code that generates 20 results for each display. There is no set number of results, so the results might have a start/first page, but do not have an end page. Each time the user hits 'next', the program would generate/load new results. It would also store previous results, so that when a user hits 'prev', the previous results can instantly come up. What techniques/program are theses?

  • External monitor turning black intermittently

    - by coding crow
    I have installed an external monitor (Dell ST2220L, 21.5 inch) on my laptop (Sony Vaio). I am using a DVI-D cable for connection. Since the laptop does not have a DVI-D port, I have connected a DVI-D to HDMI connector on the laptop end and inserted the cable in HDMI port of the laptop.. I have switched off the laptop display and adjusted the screen resolution on the Dell external monitor to 1920 x 1080 and adjusted colors for the Windows 7 and brightness and contrast from the monitor. The problem is the monitor turns of blank intermittently for 1-2 seconds and turns on again at random interval. What could be the reason for this and how to get rid of this problem?

  • Overriding CSS style 'display:none' in javascript

    - by jsarma
    I'm trying to add a checkbox toggle that hides and shows list elements by changing their style display attribute from "none" to "inline", but it's not working. I'm setting the attribute's style to "display:none" in the CSS file. Then I set it to "display:inline" in javascript when someone checks a box. The javascript is successfully changing the element's property to inline, but for some reason the element remains invisible. If I do the opposite, by setting the display to inline in the CSS and overriding it to none in the javascript, it works fine. I don't see why this would work one way but not the other. I'm using chrome. Here is the code. Any feedback is appreciated. CSS file: #tabmenu li[status='disabled'] a, a.active, #disabled { color: #777777; background: #DDDDDD; font: normal 1em Arial; border: 1px solid black; border-radius: inherit; padding: 0px 5px 0px 5px; margin: 0px; text-decoration: none; cursor:hand; display:none; } HTML: <ul id="tabmenu"> <li name='tab' id='tab1' selected='no' status='disabled'></li> </ul> JAVASCRIPT (from command line, or onchange of a checkbox) tab = document.getElementById('tab1'); tab.style.display = 'inline';

  • [Android] Is disabling landscape mode unforgivable?

    - by Nicolas Raoul
    Our application could support landscape mode without any problem, but it is such a pain that we are thinking about forcing portrait mode. Question: Is it BAD? The main problem is that changing orientation generates random crashes on many screens. Avoiding those crashes would potentially allow us to spend more time on the core aspects of the app. Will the same crashes happen when users switch apps anyway? Also, are there landscape-oriented devices where our app will become useless?

  • Override <customErrors mode="Off"/> message from .NET Framework even when in web.config detailed err

    - by GrZeCh
    Hello, is this possible to override .NET Framework error: Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. ... <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration> even if web.config (IIS7.5) is set to <httpErrors errorMode="Detailed"/> ? I'm asking because my default setting for IIS7 is <deployment retail="true" /> so no error is being showed and only adding additional error handling module to website will allow to see errors generated by this application and thats why I want to override this message to inform users about it. Any ideas? Thanks

  • Communicating via Command Mode with IBM HS22 IMM via AMM

    - by MikeyB
    On previous model blades that contained a BMC, I was able to communicate from our external management station via pass-through commands to the BMC to do things such as power blades on/off, set VPD parameters, reboot the BMC, etc. Now on the HS22, a bunch of things happen differently. For example, we can no longer use the same pass-through commands to write VPD information pages and have them persist across reboots of the IMM - it looks as though those VPD pages are populated from information contained in the IMM. How do we use the Advanced Settings Utility from an external host to communicate with HS22 IMMs? Alternatively, what TCP Command Mode commands do we need to send to the AMM to communicate with the IMM? For our purposes, we specifically cannot communicate with the IMM from the blade itself. Specific example: When I send a pass-thru IPMI command via the AMM to the blade BMC to write information (such as MTM, Serial) into VPD page 0x10, it persists on blades with a BMC (HS21 for example). I can send the same IPMI command to write data to the VPD page on the HS22, however it does not persist across reboots of the IMM. What IPMI commands do I need to send to the IMM? What IPMI commands are asu sending when it sets the MTM & Serial?

  • Acer LCD says "no signal"

    - by Ken
    I have an Acer 24" LCD (model "AL2423WDR") that's about 3 years old. It worked perfectly for most of its lifetime so far. Recently it started giving problems. When I turn it on, it either says "no signal" on the display, or the power light goes yellow (as if in power-saving mode). This happens with both DVI and VGA (both of which worked fine before), and stranger still, the 4 buttons on the front, for accessing the on-screen menus, don't do anything. I've also tried different computer hardware and software (PC/Mac, Linux/MacOS), but nothing has worked. I've tried power-cycling it (with both the power button and the power switch), and also unplugging it entirely. The nonworking buttons suggest to me an issue with the firmware. I found a place on Acer's website that says I can send it in to have it fixed, at my expense, but I'll avoid that if I can. Is there a way to fully reset it manually? Or is there something else I can try?

  • Excel 2010 data validation warning (compatibility mode)

    - by Madmanguruman
    We have some legacy worksheets that were created in Excel 2003, which are used by LabVIEW-based test automation software. The current LabVIEW software can only handle the legacy .xls format, so we're forced to keep these worksheets as-is for the time being. We've migrated to Office 2010 and when working with these worksheets, I see this warning: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all of your features, click Cancel and then save the file in one of the new file formats." "Significant loss of functionality" "One or more cells in this workbook contain data validation rules which refer to values on other worksheets. These data validation rules will not be saved." When I click 'Find', some cells that do indeed have validation rules are highlighted, but those rules are all on the same worksheet! We're using simple list-based validation, with some cells off to the side containing the valid values (for example, cell B4 has a List with Source "=$D$4:$E$4") This makes no sense to me whatsoever. One, the workbook was created in Excel 2003, so obviously we couldn't implement a feature that doesn't exist. Secondly, the modifications we're making don't involve changing the validation rules at all. Thirdly, the complaint that Excel is making is incorrect! All of the rules are on the same worksheet as the target. As if the story wasn't bizarre enough: I went ahead and saved the worksheet with Excel 2010. I then went to an old computer back in the lab and opened the document with Excel 2003. Guess what - the validations were untouched! My questions are: is this a legitimate bug in Excel 2010, or is this some exotic error in the legacy .xls worksheet that is confusing the heck out of Excel 2010? Has anyone else observed this issue working in compatibility mode?

  • Adobe Acrobat Reader don't zoom out the page enough in "one page" mode

    - by mbaitoff
    I'm using Adobe Acrobat Reader version 9.4 under Debian Lenny. I'm experiencing a problem: when I push the "Show one page at a time" button, I expect the page to zoom such that pressing PgUp/PgDn would turn to the next/previous page. However, the zoom seems to be not enough - very thin bottom portion of the page doesn't fit inside the reader window, and pressing PgUp/PgDn gives the jitter of the same page, and I have to push twice to get to the next page. It is even worse in continuous page mode - a roll of pages begin to be non-synced with window boundaries, ending up with page break right in the middle of the view after several turns of the pages. This behaviour doesn't occur on windows version - I have a page properly zoomed in single/continuous modes, so that turning the pages is performed as page-at-once, as intended. How to make the Acrobat Reader fit the page to window properly? Thats how it looks before pressing PgDn (notice the bottom edge of the "paper" hidden beneath the bottom window edge): Thats how it looks after pressing PgDn (notice the "paper" bottom edge emerged from beneath the window edge, while the "paper" upper edge hides behind the upper window edge, showing that the document window size is not enough to contain the whole page):

  • Virus ridden computer freezes on startup - can't access safe mode

    - by Eric
    Someone whom I love but who cannot be trusted with a live internet connection downloaded a particularly nasty virus that in turn downloaded a variety of unknown other viruses onto my home computer. The computer now freezes completely a few seconds after reaching the desktop and is unresponsive to any keyboard or mouse command. There are videos of my little kid on this hard drive that are not backed up and that I cannot bear to lose. But if I could get in there long enough to copy them off to an external drive I would have no problem doing a clean windows install to fix the problem; everything else is backed up online but the videos were too large. Normally I would start by going into safe mode but I have a large Dell monitor that doesn't show anything until the welcome screen appears. I think that I have gotten into the setup screen once or twice by mashing keys before I can see anything, but this monitor doesn't support that so I can't see what I'm doing to get it to boot from CD or anything else. I'm at my wits end. Any advice?

  • Troubleshooting: Monitor never turns on, system fans running, DVD-ROM does not open.

    - by Wesley
    Hi all, Here are my specs beforehand: ECS P4VXASD2+ (V5.0) motherboard FSB 533MHz Intel Pentium 4 2.40A GHz Prescott Socket 478 2x 256MB PC2100 DDR RAM, 2x 256MB PC133 SDRAM CoolMax 350W PSU DVD-ROM - will edit with brand & model 128MB ATi Radeon 9800 Pro AGP No hard drive So, I just put those parts together today and I tried to power it up, with the monitor connected to the Radeon 9800 in the AGP slot (mobo does not have VGA port). After turning it on, the CPU fan, graphics fan and system fan go on. However, the monitor remains in standby mode, despite being plugged in. Also, after pushing the button on the DVD-ROM drive, it does not open. I've used the DVD-ROM drive before with absolutely no issues. The graphics card was slightly buggy when I put it on another machine, which was left outside in winter weather for 3 months. (Still that computer's integrated graphics worked fine.) CMOS battery was replaced and jumpers are all set correctly. Now, I'm wondering whether the motherboard, CPU, PSU or GPU is the problem. What can I do to test which part is the problem? Just to clarify, I don't have a hard drive, so I usually boot Ubuntu from the disc drive. Anyways, thanks in advance!

  • Ubuntu Laptop as a wireless hotspot on bridge mode

    - by nixnotwin
    I have a wired router to which my ubuntu laptop connects via ethernet. The wierless NIC of the laptop acts as a wireless hotspot on master mode. I use hostapd fo this. I have bridged eth0 and wlan0, so my wireless clients that connect to my laptop over wifi get ip from the wired router via dhcp, so the devices get registered at the wired router ( and the laptop is just an access point). I use the following commands to get my laptop+accesspoint working: sudo brctl addbr br0 sudo brctl addif br0 eth0 sudo hostapd /etc/hostapd/hostapd.conf & sudo dhclient -d br0 & sudo ifconfig wlan0 192.168.1.15 netmask 255.255.255.0 up sudo brctl addif br0 wlan0 These commands enable me to access internet on my wireless clients and also on the laptop which is acting as wireless accesspoint. But if I reboot the wired router (without rebooting the laptop that is acting as accesspoint), Internet access on the laptop+accesspoint gets lost, but on wireless clients it works fine. Even I have not been able to figure out a command which will reset the laptop interfaces to default settings, so everytime the router reboots, I have to reboot the laptop too to get into default settings so that I can re-enter the above mentioned commands. My first question is How can I have my bridge+accesspoint up and running even-though the router reboots? And is there a command to set the interfaces to a default state? (ifdown -a doesn't work, after issuing the command the bridge still remained).

  • Configuration for httphandler in classic mode

    - by happyspider
    I have to install an httphandler that needs to run on classic mode. I have created an application on the iis that uses a classic apppool and put the handler assembly there. The vendor gave me a configuration in the deployment document that looks like this: <system.web> <globalization requestEncoding="iso-8859-1" responseEncoding="iso-8859-1" /> <httpModules> </httpModules> <httpHandlers> <add verb="*" path="*" type="ProductName.ProductName, ProductName" /> </httpHandlers> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <handlers> <add name="someUnspecificName" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv2.0,bitness32" /> </handlers> </system.webServer> The error I get when requesting a URL on the application is a 404, so I guess the handle is not used at all. Does the configuration look ok for a 64bit system?

  • Xbox Music ignores Asus FN media keys in Desktop Mode

    - by Ruud Lenders
    I have an Asus PRO64JQ laptop, and I recently upgraded to Windows 8. The FN keys stopped working, so I tried to install default drivers using the CD that came with my laptop. Unfortunately, the CD does not support Windows 8. Asus Support does not help me either. It seems that Asus does not support Windows 8 on my model, since I can't find it in their list of Windows 8 upgradable models. Also, the support page of my laptop does not allow me to select Windows 8 as OS. That's why I'm asking my question here. I fixed (most of) the FN keys by installing the ATKPackage, and I was happy to find out that the media keys (play/pauze, next, previous) works with the Xbox Music app. But the keys only work in the Metro UI. In Desktop Mode, pressing FN+? (play/pause) starts up Windows Media Player. Disabling Windows Media Player through the control panel stops it from popping up, but Xbox Music still only responds to them in the Metro UI. I remember that I had similar problems when I tried to make these media keys to work with iTunes on Windows 7. The fix there was a small iTunes plug-in. So tell me, do you know how to fix my problem? Thanks.
