  • Using the Onboard VGA output with a PCIe video card. Both nVidia

    - by sebikul
    I have 2 video cards, one On board, a nVidia 6150SE nForce 430 and a PCIe nVidia GeForce GT 220 1GB DDR2 RAM I have already configured the PCIe card to use the dual monitor feature, using the VGA and HDMI ports, but now I want to add a third monitor, using the On board VGA port I have managed to enable the On board graphics processor, which is taking 400MB of ram, but I cant manage to use it, nvidia-settings does not detect it, like it's not usable (but is there) My questions are the following: How can I manage to get the On board VGA display to work together with the PCIe graphics card? If possible, how can I recover those 400 MB the on board card is taking (even without being used) or how can I get it to use the PCIe card available memory? System Details: Linux 2.6.35-28-generic i686 Ubuntu 10.10 (All updates installed) NVIDIA Driver Version: 260.19.06 (Official) If more info is needed please let me know. Here is the lspci output when the On board card is disabled: 00:00.0 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a1) 00:01.0 ISA bridge: nVidia Corporation MCP61 LPC Bridge (rev a2) 00:01.1 SMBus: nVidia Corporation MCP61 SMBus (rev a2) 00:01.2 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a2) 00:01.3 Co-processor: nVidia Corporation MCP61 SMU (rev a2) 00:02.0 USB Controller: nVidia Corporation MCP61 USB Controller (rev a3) 00:02.1 USB Controller: nVidia Corporation MCP61 USB Controller (rev a3) 00:04.0 PCI bridge: nVidia Corporation MCP61 PCI bridge (rev a1) 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2) 00:06.0 IDE interface: nVidia Corporation MCP61 IDE (rev a2) 00:07.0 Bridge: nVidia Corporation MCP61 Ethernet (rev a2) 00:08.0 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2) 00:09.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0b.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0c.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 6150SE nForce 430] (rev a2) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:09.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 08) 02:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2) 02:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1) And this is when both are enabled: 00:00.0 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a1) 00:01.0 ISA bridge: nVidia Corporation MCP61 LPC Bridge (rev a2) 00:01.1 SMBus: nVidia Corporation MCP61 SMBus (rev a2) 00:01.2 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a2) 00:01.3 Co-processor: nVidia Corporation MCP61 SMU (rev a2) 00:02.0 USB Controller: nVidia Corporation MCP61 USB Controller (rev a3) 00:02.1 USB Controller: nVidia Corporation MCP61 USB Controller (rev a3) 00:04.0 PCI bridge: nVidia Corporation MCP61 PCI bridge (rev a1) 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2) 00:06.0 IDE interface: nVidia Corporation MCP61 IDE (rev a2) 00:07.0 Bridge: nVidia Corporation MCP61 Ethernet (rev a2) 00:08.0 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2) 00:09.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0b.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0c.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 6150SE nForce 430] (rev a2) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:09.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 08) 02:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2) 02:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1) Output of lshw -class display: *-display description: VGA compatible controller product: GT216 [GeForce GT 220] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:02:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:18 memory:df000000-dfffffff memory:c0000000-cfffffff memory:da000000-dbffffff ioport:ef80(size=128) memory:def80000-deffffff *-display description: VGA compatible controller product: C61 [GeForce 6150SE nForce 430] vendor: nVidia Corporation physical id: d bus info: pci@0000:00:0d.0 version: a2 width: 64 bits clock: 66MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:22 memory:dd000000-ddffffff memory:b0000000-bfffffff memory:dc000000-dcffffff memory:deb40000-deb5ffff If what I'm looking for is not possible, please tell me, so I can disable the On board card and recover those 400MB of wasted RAM Thanks for your help!

  • Accessing vars from another clojure namespace?

    - by erikcw
    In my main namespace, I have a top level var named "settings" which is initialized as an empty {}. My -main fn sets the contents of settings using def and conj based on some command line args (different database hosts for production/development, etc). I'm trying to access the contents of this map from another namespace to pull out some of the settings. When I try to compile with lein into an uberjar, I get a traceback saying "No such var: lb/settings". What am I missing? Is there a more idiomatic way to handle app wide settings such as these? Is it safe to use "def" inside of -main like I am, or should I be use an atom or ref to make this threadsafe? Thanks! (ns main (:use ...) (:gen-class)) (def settings {}) (defn -main [& args] (with-command-line-args... ;set devel? based on args (if (true? devel?) (def settings (conj settings {:mongodb {:host "127.0.0.1"} :memcached {:host "127.0.0.1"}})) (def settings (conj settings {:mongodb {:host "PRODUCTION_IP"} :memcached {:host "PRODUCTION_IP"}}))) ;file2.clj (ns some-other-namespace (:require [main :as lb] ...) ;configure MongoDB (congo/mongo! :db "dbname" :host (:host (mongodb lb/settings)))) ...

  • Associating a modifyable settings file with a class library in C# ?

    - by mishal153
    I have a class library(abc.dll) in which i have used a settings file. An exe (app.exe) references this class library. At runtime if i want to change the values of the settings without having to rebuild the class library/application, what is the best way to approach this problem ? In my current approach the setting values get embeded in the library, and thus i dont see any way to update them without rebuilding the whole thing.

  • Dual monitor not working completely in 12.10 after upgrade

    - by Mark Baldridge
    At 12.04, dual monitors worked perfectly. After upgrading to 12.10, the primary monitor works, the second monitor only partly works. I am sure there is some difference between the releases that I have missed setting properly. System settings - Displays show both correctly as Acer 22" monitors at 1680x1050 (16:10). An icon on monitor 2 is present, but elongated; almost an artifact, since other icons on the primary screen are absent, but this one icon is there on th second monitor. Selecting the icons on both screens exist. Painting is weird on monitor 2. Launcher exists and works on both screens, but even with sticky edges off, the cursor stops at the left edge of monitor 2. Clicking on text editor on screen 2 launcer will launch gedit there. If I drag it, it leaves a trail of after images like repaint is failing. If I drive the cursor on the launcher, the help tags like "LibreOffice Writer" appear, but stay on screen unless I drag the active gedit window over them. Then part of the help bubbles are overwritten, leaving behind after images of the gedit window on screen. What is really fascinating is that the System settings - Displays is now ignoring monitor selection, after allowing it earlier. Just before this, the help popup which said "Select a monitor to change its properties; drag to rearrange its placement" actually let me do that. Maybe a trick of where I grab the edge of the monitor in the Displays setting. I just found a working handle. When I drag monitor 1 to the right of monitor 2, "Apply" and confirm, both monitors work normally (although the right monitor lets the cursor slide off the right edge onto the left edge of monitor 1 - which sounds correct). Painting of windows does not leave an after image. However, success is only temporary. The setting survives the reboot, but painting on the left monitor, now monitor 2, now replicates the issues from before. The after image of the gedit window and the small window for "Are you sure you want to close all programs and restart the computer?" are still on monitor 2 (on the left now), even though they are not real windows, nor do they have processes behind them. Curiously, in Displays, the "green" monitor on the left in the display window is matched by the right monitor color in the monitor upper left corner. Probably makes sense as the one on the right is now monitor 1. If I repeat the "drag the left monitor to the right of the right monitor on the "Displays" window, things are oriented properly, with no display artifacts as I drag windows around either screen. Also the description bubbles that pop up are overwritten on both screens, so none of those artifacts either. This goodness does not survive a reboot, however. Have not tried logging out and back in. All of this after positing that the motherboard VGA and HDMI ports could have been the issue. So, I installed an e-GeForce 7600 GT Dual DVI (I know the web thinks it is not DVI, but VGA, but the connectors are DVI). No change to the weird behavior. The good parts continue to work, the weirdness also works, and swapping monitor positions seems to cure the issue. So, is there a setting I have missed? Given "swapping" monitor 1 and 2 on the System Settings... - Displays makes it work, just not across boot, I suspect so.

  • How to display an array's content in colomns, like ls -C does.

    - by Arko
    I wanted to display a long list of strings from an array. Right now, my script run through a for loop echoing each value to the standard output: for value in ${values[@]} do echo $value done Yeah, that's pretty ugly! And the one column listing is pretty long too... I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).

  • Tempescope Displays Weather by Recreating It

    - by Jason Fitzpatrick
    Yesterday we showed you an umbrella stand that signals raining/clear skies by color, today we have something even more interesting: an ambient desktop weather station that recreates the outside weather. The Tempescope pulls down the current weather report from Weather Underground’s API and feeds it to an Arduino board which in turn controls the device. When it’s raining, it pumps water down to simulate rain in the chamber. When there is lightening, LEDs flash. When there is cloud cover, an ultrasonic generator creates a fine mist inside the cylinder. Finally, on sunny days the entire thing glows warmly. To say that we want one would be an understatement. Hit up the link below to read more about the project, the display modes, and to peek inside the device.

  • Dual monitor, with a low resolution projector

    - by user900978
    I need to show a presentaion to a conference tomorrow. Today I tryed my Ubuntu 10.04 with the projector. My notebook has a resolution of 1440x960, the projector seems to have a really lower resolution. However, thanks to nvidia-settings I configured my video card (a nvidia 9800), it works with other display, but not with the projector. I found the projector, configured as Twin-view, resolution Auto and pressed on Apply, then "Save to x Configuration". On projector is visualized just a quarter of my notebook display. I tryed also to reduce my resolution and to change the resolution of projector, but I obtained no better results. How can I Solve it? On windows all goes well, but I need Ubuntu for personal reasons. Thanks in advance

  • How do I change my 1080p external monitor from portrait to landscape on an Eee PC 1000H?

    - by Acky
    Hi I have an EeePC 1000H netbook with a Samsung T22A350 1080p 22" external monitor. I've just installed Ubuntu 12.04 and I mainly use the external display but when I select 1080 from the dropdown list, my only options are for a rotated portrait. My neck's non too supple, so tilting my head for extended periods is not really viable. :-) Any ideas on making ubuntu display 1080 normal landscape? It must be possible as using a gparted boot cd does it perfectly. Any help greatly appreciated. Cheers!

  • Is it possible to have my desktop loaded before login?

    - by Dims
    I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?

  • Why does Ubuntu 10.10 show blank screen during startup?

    - by user8372
    When I try to login to Ubuntu 10.10 I get a flickering screen for a second showing - Ubuntu 10.10 ............. and then I get a blank purple coloured screen[Ubuntu's theme colour] which doesn't progress any further Can anybody suggest a remedy to this problem? From whatever questions I searched in various Ubuntu Forums it seems like this problem is likely caused by a missing NVIDIA Display Driver[which is being used in my Sony Vaio Laptop] update in Ubuntu releases If that's the case then how can I update my NVIDIA Display Driver for Ubuntu 10.10 without being able to log into the Ubuntu 10.10?

  • Display subclass data in XCode Expression window

    - by Nick VanderPyle
    I'm debugging an iPhone application I've written using XCode 3.2 and I cannot view the relevant public properties of an object I pull from Core Data. When I watch the object in the Expressions window it only displays the data from the base NSManagedObject. I'd like to see the properties that are on the subclass, not the superclass. If it helps, here's some of the code I'm using. Settings is a subclass of NSManagedObject. I created it using XCode's built-in modeler. Declared like: @interface Settings : NSManagedObject { } @property (nonatomic, retain) NSNumber * hasNews; @property (nonatomic, retain) NSString * logoUrl; @property (nonatomic, retain) NSNumber * hasPaymentGateway; @property (nonatomic, retain) NSString * customerCode; ... In the interface of my controller I have: Settings *settings; I populate settings with: settings = (Settings *)[NSEntityDescription insertNewObjectForEntityForName:@"Settings" inManagedObjectContext:UIAppManagedObjectContext()]; I then set the properties like: settings.hasNews = [NSNumber numberWithBool:TRUE]; I've tried casting settings as (Settings *) in the Expression window but that doesn't help. All I see are the properties to NSManagedObject. I'm using NSLog but would rather not.

  • How to preserve sysprep from changing Default User settings

    - by user33794
    I'm having diffculties configuring 20 new Dell Vostro minis here. I set up one of them with my preferred OS, applications and settings, especially the Visual Effects Settings of Windows XP. I set them to best performance and deactivated everything else in the box. I copied this profile to Default User Profile and did sysprep -mini -reseal. After capturing this image and deploying it again, the desktop settings are correct except the visual effects settings. fading and everything else is reenabled for each new user which is created on the system. How do I preserve my settings from being overwritten by sysprep? thanks!

  • Restore access to Cisco Connect after changing router settings

    - by StasM
    I have recently bought Cisco Valet Plus (M20) wireless router (which I recognize now was a mistake, but nevermind). It has two setup options - Cisco Connect software and web-based setup. Cisco Connect software allows changing very small set of settings, web-based setup allows access to almost all settings, except settings for guest network. The problem is that when I use web-based setup, Cisco Connect after some changes refuses to talk to the router, so I can't change guest settings anymore (since web interface doesn't allow to change them). It must be because of some config parameter not matching or some password set wrong - but I don't know where Cisco Connect stores them. So, does anybody have any idea how to make Cisco Connect talk to the router again once I changed the settings through the web interface?

  • How can I stop Windows DNS server properties settings from changing by themselves?

    - by paradroid
    When I open the DNS console in Administrative tools, I keep finding a couple of problems which keep on reappearing by themselves, and I want to stop them from happening. One of the DNS servers has two network interfaces, and it should only be listening for requests on of them, and I get errors in the Event Log otherwise. But when right clicking one DNS server and selecting Properties, I can see on the Interfaces tab that 'All IP addresses' is selected. If I Change it to 'Only the following IP addresses:' and deleselect the WAN addess, I will find it reslected when I next check it after a couple of days. In the other DNS server's Properties, on the Forwarders tab, there should only be two forwarder addresses. However, the address for the router keeps in appearing. This router has the DNS server as its forwarder. There shouldn't be anything using the router's DNS forwarders for DNS other than the router itself, but this surely is causing a loop. How do I get these properties on both DNS servers to stick?

  • Mac webcam photo application with access to camera settings (resolution, camera selection, color balance, focus)

    - by Pascal T.
    Does anyone know about a webcam photo application (ie an alternative to photo booth) with would allow to change the settings on the camera, such as : Select camera (I.e I want to use an external webcam) Change camera resolution (with photobooth change camera settings (I.e autofocus, aperture, color balance, etc..) I did a lot of research on the internet with no success. I am looking for a very simple app (such as wmcap.exe on Windows) What I tried so far: photo booth: it works with an external camera, however there is no way to change the resolution, or the color/focus settings manycam : a virtual webcam driver. you can add special effects to your camera and transfer those effects to any app, but not change your camera settings... iGlasses : enables you to change the camera settings inside photo booth and other apps. However you cannot control the focus, nor the video resolution macam (did not work on my Mac book Pro) Does anyone know better than me? Note : my only solution now is to launch a virtual machine (with parallels desktop) and take the pictures from there!

  • Dual monitors won't accept new settings

    - by mschulze
    I'm trying to use dual monitors but every time I try to change the display settings(external monitor is on the right of the laptop, not the left etc...) my screens go black, then my laptop screen will come back "normally" but my external monitor will just flash different shades of red or black. I cannot interact with anything on my laptop screen even though I can move my mouse around. Even when the monitors attempt to revert back the external monitor continues to flicker instead of reverting. The only way to stop it is to hard-boot but the new settings aren't saved. Also, when the dual monitors are both working my laptop screen has two vertical black bars along its sides. It's like Natty just decided I couldn't use the outer inch and a half of my laptop screen. My external monitor doesn't have this problem, and my laptop uses its full screen size when the external monitor is not hooked up. Does anyone know what I'm doing wrong? I have an HP Pavillion dv7 and an HP w2338h external monitor. Thanks!

  • nVidia Settings: Overriding anti-aliasing causes delay

    - by Kalle Elmér
    I'm using Google Sketchup on ubuntu 12.04 with Wine 1.4. It works flawlessly out of the box, but anti-aliasing is causing some problems. I can override anti-aliasing settings using the nVidia X Server Settings utility, which results in a great-looking image. However, the view doesn't seem to update properly. It's a bit hard to explain, but if I do something (e.g. zooming) the changes won't appear in the view until I take another action. in other words, there seems to be a delay of one "action". Take this example. The mouse wheel is moved one notch to zoom in one step. Nothing happens. An object is selected by clicking. The new zoom is rendered but the selection box doesn't appear. An empty area is clicked. The selection box appears. Is there something that I can do to solve the problem? Could I force the GPU to redraw that view with a certain interval, or is there some other solution? I really like anti-aliasing, but it's hard to use when drawing stuff.

  • Can't change settings for Mobile Broadband Dongle - Button is greyed out

    - by Ross LIndsey
    I was with VirginBroadband.com.au (Australia). My huawai 3G Dongle was working great on Ubuntu, However I have changed ISP's. I unlocked the modem, and put in the new SIM. I have tested this in my Windows PC and it connects to the new (Optus) Network A-OK and it all works. When I put this dongle (the same one that was working fine in Ubuntu) into that same Ubuntu Netbook it simply won't connect. When I try to go into the dialog to try and add or change settings the button to change or update settings is greyed out, I can't select it. Apparently since this dongle was already recognized the Broadband Setup Wizard won't start, and I have no idea how to get it to start (presuming it has the ability to configure an already recognized dongle). What do I have to do to either enable the ability to change the configuration for this setup, or to blow away the one that is set up so the Broadband Wizard will re-start and let me configure a new one. Can anyone provide simple instructions for doing this? I'm using Ubuntu with the Cinnamon Desktop

  • Unwanted Chinese language got set in system settings

    - by Registered User
    I was discussing on the Ubuntu users list how to type in in Hindi (Indic language) in Libre Office and about a package installation problem. I have made some changes in system settings, following suggestions by some users. However, this morning when I did a reboot I am unable to see English as my default language. My system is showing some Chinese characters which I do not understand. All I wanted was to use Libre Office for a particular document in Hindi. What happened is that even Gmail is opening in Chinese. The system settings folder and others are also opening in Chinese. I am unable to use the system now. I have uploaded the snapshots here: please have a look. Upon a reboot, I was asked to rename all folders. Gmail opening in Chinese This is how menu on my system looks: half English and half Chinese Notice that in the third snapshot the calendar and menu are appearing in Chinese. I want the original US English menus and folder names back. I just wanted to type a document with Lohit Hindi font in Libre Office. I use Ubuntu 11.10. I do not use Unity, only Gnome desktop. I installed gnome-session-fallback a long time back and have been using that ever since. How do I get back to all English submenus and English folder names? I have a US English Keyboard and I use only US English. This thing which is now somehow set is unwanted.

  • Tweaking a few URL validation settings on ASP.NET v4.0

    - by Carlyle Dacosta
    ASP.NET has a few default settings for URLs out of the box. These can be configured quite easily in the web.config file within the  <system.web>/<httpRuntime> configuration section. Some of these are: <httpRuntime maxUrlLength=”<number here>”. This number should be an integer value (defaults to 260 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. This attribute gates the length of the Url without query string. <httpRuntime maxQueryStringLength=”<number here>”. This number should be an integer value (defaults to 2048 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. <httpRuntime requestPathInvalidCharacters=”List of characters you need included in ASP.NETs validation checks”. By default the characters are “<,>,*,%,&,:,\,?”. However once can easily change this by setting by modifying web.config. Remember, these characters can be specified in a variety of formats. For example, I want the character ‘!’ to be included in ASP.NETs URL validation logic. So I set the following: <httpRuntime requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,!”. A character could also be specified in its xml encoded form. ‘&lt;;’ would mean the ‘<’ sign). I could specify the ‘!’ in its xml encoded unicode format such as requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,$#x0021;” or I could specify it in its unicode encoded form or in the “<,>,*,%,&,:,\,?,%u0021” format.

The value of the public property HttpRequest.PhysicalPath is set to [physical file path of the application root] + "REQUEST_URL_IS_NOT_A_VALID_FILESYSTEM_PATH". For example, given a request Url like "/foo/bar/baz/<blah>data</blah>", where the application root is "/foo/bar" and the physical file path for that root is "c:\inetpub\wwwroot\foo\bar", then PhysicalPath would be "c:\inetpub\wwwroot\foo\bar\ REQUEST_URL_IS_NOT_A_VALID_FILESYSTEM_PATH".

  • Tweaking a few URL validation settings on ASP.NET v4.0

    - by Carlyle Dacosta
    ASP.NET has a few default settings for URLs out of the box. These can be configured quite easily in the web.config file within the  <system.web>/<httpRuntime> configuration section. Some of these are: <httpRuntime maxUrlLength=”<number here>” This number should be an integer value (defaults to 260 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. This attribute gates the length of the Url without query string. <httpRuntime maxQueryStringLength=”<number here>”. This number should be an integer value (defaults to 2048 characters). The value must be greater than or equal to zero, though obviously small values will lead to an un-useable website. <httpRuntime requestPathInvalidCharacters=”List of characters you need included in ASP.NETs validation checks” /> By default the characters are “<,>,*,%,&,:,\,?”. However once can easily change this by setting by modifying web.config. Remember, these characters can be specified in a variety of formats. For example, I want the character ‘!’ to be included in ASP.NETs URL validation logic. So I set the following: <httpRuntime requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,!”. A character could also be specified in its xml encoded form. ‘&lt;;’ would mean the ‘<’ sign). I could specify the ‘!’ in its xml encoded unicode format such as requestPathInvalidCharacters=”<,>,*,%,&,:,\,?,$#x0021;” or I could specify it in its unicode encoded form or in the “<,>,*,%,&,:,\,?,%u0021” format. The following settings can be applied at Root Web.Config level, App Web.config level, Folder level or within a location tag: <location path="some path here"> <system.web> <httpRuntime maxUrlLength="" maxQueryStringLength="" requestPathInvalidChars="" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } If any of the above settings fail request validation, an Http 400 “Bad Request” HttpException is thrown.
