  • C# multiple asynchronous HttpRequest with one callback

    - by aepheus
    I want to make 10 asynchronous http requests at once and only process the results when all have completed and in a single callback function. I also do not want to block any threads using WaitAll (it is my understanding that WaitAll blocks until all are complete). I think I want to make a custom IAsyncResult which will handle multiple calls. Am I on the right track? Are there any good resources or examples out there that describe handling this?

  • mysql meeting multiple conditions

    - by Djeux
    I'm having a table, where one ID, can have multiple statuses | client_id | status_id | | 1 | 2 | | 1 | 3 | | 1 | 5 | | 2 | 2 | | 2 | 3 | | 2 | 6 | The problem is, to select only those client_id's if they have all the statuses i.e. 2,3,5 (status_id = 2 AND status_id = 3 AND status_id = 5) but mysql doesn't allow that directly.

  • Windows XP over two monitors, but one of them switches off at boot... how to fix? How to switch bac

    - by jae
    When booting into XP (x64, Athlon II X2 245, 4GB RAM), my main monitor (got two 19" TFTs hooked up, two gfx cards, a 4650 (1GB, the primary monitor's on this) and a 4350 (512MB)) switches off. Logging in blind (cursor down key, typing password) gets me one screen, the secondary. Booted correctly until about two days ago. No clue what's the cause, last change was (if I don't overlook something) installing the ATI 9-12 hotfix. And booting into Windows 7, after returning from 7, it was like this. For some weird reason, I cannot start Catalyst Control Center (I right-click desktop, choose the CCC entry, the pointer changes to hourglass for a half-second... and nothing. Likewise with "Properties"... I think, as all windows open on the primary (off) screen, and no entry appears in the task bar for Properties) Completely stumped. Windows 7, same setup, works w/o a hitch. The primary monitor appears to run in some unknown, but pretty low, resolution, as the mouse pointer only moves onto it at about half-height. But, w/o CCC or display properties, I cannot check. And, obviously, not change anything. Hope this was not too long-winded. And I'm sure I still forgot essential stuff. :P

  • PropertyGrid: Merging multiple dynamic properties when editing multiple objects

    - by Andrei Stanescu
    Hi, Let's say I have a class A and a class B. I would like to edit using .NET PropertyGrid multiple instances of A and B simultaneously. The desired behavior would be to have the intersection of properties displayed. If A and B have static (written in the source code) properties everything works fine. Selecting A and B instances will only display the intersection of properties. However, if A and B also have dynamic properties (returned as a PropertyDescriptorCollection through the GetProperties() method) the behavior is wrong. When selecting multiple objects I will only see those static properties and none of the dynamic ones. When I select only one instance I can see all properties (static and dynamic). Anybody any ideas? I couldn't find anything on the internet.

  • Best way to mount 3-4 monitor like this?

    - by jasondavis
    I just purchased 2 HP 2009m widescreen monitors, they are not the biggest thing on the block, they are like 19-20" and are only around 150-200$ so I think they are perfect. I bought 2 of them just to make sure I like them, with the full intention of purchasing more to make either a tripple or quad display. I now I am stuck trying to decide, if I purchase 1 more to have a tripple display I would then like to just wrap the third monitor to either the rigth or left side, I could do this without a mount most likely pretty easy. If I decide to go with 2 more monitors to make a quad display then I would like to add the 2 new monitor directly above the 2 that I have now. So it would make a grid of 2 wide and 2 high. I have posted a few photos belwo to show them now with the 2 I have, you will notice that I have them tilted inwards to make more of a "V" shape instead of them being side by side and "STRAIGHT". Now if I decide to make thegrid of 4 then I will need to buy or build a stand to hold them all tightly together (no whitespace or gap between the grid of monitors) but I would like to still have both rows invert to make the slight "V". Do you know of any existing stands I could purchase that would hold all 4 monitors without making them be STARIGHT without the "V" shape? Any tips appreciated please, also they do have holes in the back for VESA. a few photos... (they are from iphone and lighting made them note very good but you can see what I am working with here)

  • LCD monitor flicker when connected to a laptop using VGA

    - by Björn Lindqvist
    I have a dual screen setup with two AOC e2450Sw monitors connected to a laptop. The laptop has one HDMI and one VGA output. When one of the monitors is connected using VGA, it flickers or displays static noise. The flickering is fairly subtle and only visible on darker colors. But it is there and noticable and appears like horizontal lines. The problem only appears on the monitor connected to the laptop using the VGA cable. If I swap the monitors, the one connected using VGA is displaying the flicker but not the one connected using HDMI. The simple solution would ofcourse be to connect both monitors using HDMI, but since the laptop only has one VGA and one HDMI out that isn't possible. I've tried tweaking the monitor setting using the OSD menu, but it had little or no effect. Update: After several more trouble shooting hours, it seems the problem is not related to the monitor or VGA cable as the problem persists even if I swap the display with another brand and different cables. So it may be the graphics card? Intel HD Graphics 4000. The laptop is Acer Aspire E1-571.

  • ASP.Net - DataRepeater with multiple templates and multiple datasources in one

    - by NicoJuicy
    This is my problem. I'm using different sql-queries for fetching some people, some come from my database and some come from an external database. They are all sorted in the same "list", only the difference is, that the people who come from our database will have a different lay-out and there will be less of them in a row (eg. 1 in a row), the list of people who come from the external database will be ordered by 3 (in a row). How can i implement this using a repeater? And how would the pagination work? Any "logical", working alternatives will be appreciated also, but i prefer to keep my current workflow to solve this problem. Short: - Multiple datasources - Multiple templates for the different datasources (1 in a row, 3 in a row) - Pagination in this problem?

  • How to use different scaling for every monitor?

    - by Mikael Koskinen
    One of the new features in Windows 8.1 is the new "Desktop display scaling", which allows user to configure scaling per monitor. I've been trying to get this working in preview but with no success. If I configure the scaling, it always affects all of my monitors. I have two monitors, the main one with a higher resolution and the secondary with "normal" resolution. The secondary monitor is used in portrait mode. I would like to configure the main monitor's scaling as the text is currently too small. Here's how things look at the configuration screen by default: Now if I adjust the scaling, click apply and do relogin, everything is bigger. On both of my monitors. I haven't clicked the "Let me choose one scaling level for all my displays", but still the slider seems to affect both of them. If I check the "Let me choose one scaling level", the UI changes to look similar to what we have in Windows 8: Still the problem persists. The scaling is applied to both of my monitors. So, it doesn't matter if I check the box or not, the scaling is always applied to all the displays. Any idea how I could get this to work in preview? I've read some comments which seem to indicate that this should work in preview, though Paul Thurrott mentioned at his Winsupersite article that he either didn't get this to work.

  • Windows 7: Dual Monitor Issue

    - by sdoca
    I have a Dell laptop with a docking station and two external monitors hooked up. I'm running Windows 7 64 bit. Originally, the two monitors were the same - Dell 1908FP. I have replaced one of them with an HP LA2405. I have set the HP 24" (1920 x 1200 connected via DVI port) as montior 1 and extended to use the Dell 19" (12080 x 1024 connected via VGA port) as monitor 2. I have set my power plan so that when the laptop is plugged in, it will turn the monitors off after 10 minutes, but it will not put my laptop to sleep. However, now that I have the HP monitor, when I unlock my laptop and the monitors come back on, all my windows are resized and shifted to the top left corner of the HP monitor as if they had been resized for display on the smaller Dell monitor. A co-worker has the exact same laptop and monitor configuration but doesn't experience this issue, so I figure there's some configuration that's different but we can't find it. I haven't been able to find any mention of a similar problem doing an internet search, but I'm not really sure what terms to use in my search. Anybody have any suggestions as to what may be causing the issue? OS setting? Monitor setting? EDIT: My laptop is using the Intel Graphics and Media Control Panel/drivers.

  • Unity 3D (with Nvidia driver) becomes very slow and laggy

    - by Graham
    How can I prevent my Unity 3D desktop from becoming slow after a while, given that I have an Nvidia Quadro NVS 290 graphics in TwinView mode? The desktop starts out fast on login, but becomes slow / lagging / hesitant / high latency after a while, symptoms being spikes in CPU usage by /usr/bin/X whenever I cause any graphical activity with the mouse or keyboard (e.g. typing, changing tabs, dragging windows). The desktop remains slow even with all windows (except htop in Terminal) and extraneous processes killed. Detail: Changing tabs in Terminal takes about a second, and X spikes to 76% CPU. As I type into Firefox, X spikes to 95% CPU. Dragging Termiinal window, X goes to 70% CPU. Basically, every graphical action sends CPU usage of X through the roof. Device: Nvidia Quadro NVS 290 Driver package: binary driver nvidia-current-updates (280.13-0ubuntu5) Dual Monitors: Pair of DELL UltraSharp 1908FP in TwinView (X screen 2560x1024) OS: Fresh install of Ubuntu 11.10 amd64 Desktop with all updates. Hardware: Dell Precision T5400 Workstation Pastebin of Xorg.0.log Pastebin of xorg.conf Pastebin of nvidia-xconfig -t output (easier to read than xorg.conf) Output of /usr/lib/nux/unity_support_test -p: To obtain the following htop screenshow I typed "asdf" several times in in this text box, alt-tabbed to Terminal and took a screenshot of the high X CPU usage. This also happens when firefox is not running: Quadro NVS 290 has "No" thermal sensor according to sensors-detect: Next adapter: NVIDIA i2c adapter 0 at 2:00.0 (i2c-0) Do you want to scan it? (YES/no/selectively): Client found at address 0x50 Probing for `Analog Devices ADM1033'... No Probing for `Analog Devices ADM1034'... No P robing for `SPD EEPROM'... No Probing for `EDID EEPROM'... Yes (confidence 8, not a hardware monitoring chip) I tried the nouveau driver by disabling the nvidia-current-updates under Additional Drivers, but Ubuntu and xrandr -q fail to detect the second monitor. This may be issue 737349. Funniest thing is that Nouveau wiki says that XRandR 1.2 dual-monitor is supported so it should work with a second monitor.

  • External monitor is blank if I boot with the monitor plugged in

    - by Ronald
    Ubuntu 12.04 has problem with Intel GM45 Chipset, featuring the the Mobile Intel® Graphics Media Accelerator (GMA) 4500MHD I have a COMPAQ Presario CQ70 laptop with an Intel GM45 chipset that features the Mobile Intel® Graphics Media Accelerator (GMA) 4500MHD. I was using the second HDMI video port to drive both a projector or a second monitor. Everything was working fine under Ubuntu 8.04, 9.04, 10.04 and 11.04, however, when I upgraded to 12.04 the second monitor stopped working. What I mean when I say stopped working is: boot with monitor plugged in. Blank screen! Power off, unplug monitor and power on everything works. Plug in monitor (only mode that works in Mirror mode) two monitors that look same. Close laptop lid. screen goes blank only option for useful system is power off and unplug monitor. If I attempt to Adjust the monitor to maximum resolution that the monitor will handle and turn off mirror mode nothing can be moved onto that screen. This all worked fine with earlier versions of Ubuntu, is there a notes about the changes to the graphics management system in 12.04, like there is for the resolver change?

  • Second monitor not detected

    - by configurator
    Note: I've seen this question quite a lot, but in all the cases I could find with answers, the answer was either "I don't know" or "use nvidia-settings (which is irrelevant to me)."

  • Cannot use second display with 12.04 and Intel 2000/3000

    - by Carolyn Marenger
    I am unable to get anything to display on my second monitor, or even get the system to recognize that there is a second screen. I am running Ubuntu 12.04 on a Gigabyte GA-H61M-S2PV, revision 2.0 box. The integrated chipset is an Intel 2000/3000, and there are both a D-Dub and a DVI-D display ports on the MB. This is the first operating system I have installed on this system. I have a second monitor plugged into the DVI-D port via a DVI-D to D-Sub adapter. I cannot verify that the motherboard or adapter were/are working, short of installing windows to test the theory. When I go into the "System Settings - Displays" control window, it shows one display. I have rebooted with the second monitor attached, and I have perused the BIOS settings in case it might have been disabled. So far, I have had no indication that the second monitor is recognized, not even a flicker at power on. If I swap monitors and cables between the DVI-D and D-Dub ports, the other monitor lights up, so I know the monitor and video cable are not the issue. Any suggestions would be appreciated. Thanks, Carolyn

  • Why does Unity not extend to my 2nd monitor, even when it is displaying an X-Screen?

    - by Gridwalker
    I recently added a 2nd video card to my system, but unity refuses to extend my desktop over to the second screen. Although the secondary monitor initialises when I boot and I can move the mouse cursor over to the 2nd screen, the screen is otherwise blank (showing no wallpaper or interface elements) and I am unable to move any windows to this monitor. Moving the mouse cursor over to the 2nd monitor changes it from the default cursor to the old-style X cursor, such as the one that appears when you run X-kill, indicating that this screen is initialised in the X Server but that Unity is not recognising it. Although the Nvidia X Server Settings application can see both monitors, the unity systems settings application does not detect the 2nd adapter. Sometimes the additional drivers application can see both adapters, but it doesn't consistently show options for them both. Xrandr also fails to detect the 2nd monitor, but iNex lists both adapters. I have experimented with several different drivers for each adapter and with setting each of the graphics cards as the primary adapter in the BIOS, but this has made little difference. The two adapters are an onboard Geforce 8200 and a PCIE Geforce 7200 GX. The onboard adapter is currently set as the primary, however this adapter crashes whenever I use the Nouveau driver and I have to switch over to the PCIE as a primary whenever I purge the proprietary drivers (switching back when the 304 driver has been reinstalled). It doesn't matter which adapter I set as my primary, the results are the same : one screen showing the unity interface and one screen showing an X-Screen that only displays the mouse cursor. All I want is to be able to run this system in a dual screen configuration. I am not a gamer, nor do I require 3D rendering capabilities. Anything you can suggest to get the desktop to extend across both screens will be massively appreciated!

  • Second Monitor Detected, but not receiving a signal after upgrading to 12.04

    - by user62458
    After I upgraded to 12.04, my second monitor is detected (in display settings), but will not power on. I have scoured the Internet and forums for a solution and I can't find anything. I have found a couple people with the same problem, but never a solution for it. I am no expert, but I'm certainly not a noob. My computer uses AMD Radeon 6250 graphics, but I do NOT want to use the proprietary graphics drivers. They refuse to work properly with my second monitor (they ATI drivers will only mirror screens, and I've done everything to try to fix it, and I DON't want mirrored screens) Not to mention that the default open-source video drivers seem to work much better than the proprietary anyway! Again, Ubuntu's default video drivers work fine, and they even DETECT the second monitor (Dell 19'). I can drag stuff off the screen and put it on the 'space' of the second monitor and even a screen-shot shows that there are two monitors active; but the monitor is OFF. It will not power on. It goes into 'power-save' mode because it is not receiving a signal. For some reason it is not getting the signal to power on, even though Ubuntu thinks the monitor is working properly. I had this working fine on my Sony VAIO yesterday (with Radeon graphics/default Ubuntu video drivers). I upgraded to a Samsung Series 3 and now I have this issue. I can't for the life of me figure out why the monitor is connected, detected and I have screen space for the monitor, but the screen won't turn on!

  • Ask the Readers: How Many Monitors Do You Use with Your Computer?

    - by Asian Angel
    Most people have a single monitor for their computers, many have two, and some individuals enjoy “3 monitor plus” goodness. This week we would like to know how many monitors you use with your computer. Photo by DamnedNice. A good majority of people have a single monitor that they use with their computers and that single monitor serves their needs very well. It could be that these individuals do not engage in a heavy amount of work or play on their computers…they just need to do the basics like checking e-mail, using I.M., working with photos, etc. Another possibility is the use of virtual desktop software such as Dexpot, Yodm 3D, or Sysinternals Desktops on Windows systems. Linux systems such as Ubuntu already have that wonderful multi-desktop functionality built in. The wonderful part about virtual desktops is that a single monitor can feel equivalent to a small army of monitors. The ability to separate your open windows into “categories” and spread them out across multiple desktops is definitely nice. With each passing year dual monitor setups are becoming more common. Having twice the screen real-estate visible at the same time can be extremely convenient when you are multi-tasking. Perhaps you like to monitor your system’s stats and an e-mail account on the second monitor while working with software on the first. It certainly beats having windows popping up and down on your screen constantly while keeping on top of everything! Next we have the people who have three or more monitors in use with their computers. This may be a result of the type of work they do, an experiment to see if multiple monitors are right for them, or the cool, geeky factor that comes with having all those monitors. Needless to say these individuals can induce a good amount of envy and/or inspiration in the rest of us when we see their awesome setups. Are you perfectly content with a single monitor? Do you have two or more monitors that you use? If you have two or more monitors are they actually that useful to you? Perhaps you are getting ready even now to add additional monitors to your system. Whatever your situation may be at the moment, let us know your thoughts (and possible multi-monitor plans) in the comments! How-To Geek Polls require Javascript. Please Click Here to View the Poll.

  • External Full HD monitor and Virtual Desktop Size

    I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf.

After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect? According to the man page, it should be fine. Any ideas?

  • How can I extend the desktop onto an external monitor/projector?

    - by hellocatfood
    I've plugged in a projector into my laptop and I'm attempting to extend the desktop onto it (so that I can run a full screen app on the projector and have the controls on my laptop). I'm able to mirror the screens effectively (it does this by default) but I can't extend it. When I untick "Mirror screens" and press apply it asks me to log out and then back in again but it goes back to mirroring the screens. I'm able to extend desktop on to my external monitor at home, just not this projector. Is there a manual way or other way to do this other that through Monitors setting? My computer model is Dell Studio 1555: Pentium Dual Core T4300(2.1GHz,800MHz,1MB), 4096MB 800MHz DDR2 Dual Channel, 512 MB ATI Mobility RADEON HD 4570 using the ATI proprietary driver. My screen resolution is 1366x768 (16:9) The projector that it wont connect properly is a Hitachi CPX3. That page specifies that it's especially designed for projectors that use 16:10 aspect ratio, but considering my external monitor at home uses 4:3 should the differences in aspect ratio matter or be causing this error?
