  • Vista Power Management GPO

    - by Matt
    Hi, I've created a loopback GPO that has several settings (both computer and user) including a Custom User Interface (Access 2007 Application) and Power Management (has the computer sleep after being idle for 2 min). I'm also filtering so that this policy does not apply to "Admins" - only to "Users". The problem I'm having is when the "Users" login the Power Management settings don’t work, but they do for "Admins". For testing I'm allowing the "Users" to launch Task Manager and use the Run line, so I'll run Explorer and look at Power Management and it shows the settings from my GPO. So I created a test OU with copies of the aforementioned GPO, but removed the Custom User Interface and found the Power Management settings do work for both the "Users" and "Admins". When I add the Custom UI the Power Management settings break for the "User" but continue to work for "Admins". Do the Power Management options need to have User Interface be "Explorer.exe"? Is this a bug or am I doing this the wrong way? BTW the tablets are using Vista SP2. Any insight or advice would be greatly appreciated. Thanks, Matt

  • Assets not served - Apache Reverse proxy - Diaspora

    - by Matt
    I have succeeded in installing Diaspora* on my subdomain diaspora.mattaydin.com. I have VPS running CentOS 5.7 with Plesk installed. By means of an vhost.conf and vhost_ssl.conf file I, (with the help of another gentleman) have managed to reverse proxy the app. vhost.conf: ServerName diaspora.mattaydin.com ServerAlias *.diaspora.mattaydin.com <Directory /home/diaspora/diaspora/public> Options -Includes -ExecCGI </Directory> DocumentRoot /home/diaspora/diaspora/public RedirectPermanent / https://diaspora.mattaydin.com vhost_ssl.conf ServerName diaspora.mattaydin.com DocumentRoot /home/diaspora/diaspora/public RewriteEngine On RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://upstream%{REQUEST_URI} [P,QSA,L] <Proxy balancer://upstream> BalancerMember http://127.0.0.1:3000/ </Proxy> ProxyRequests Off ProxyVia On ProxyPreserveHost On RequestHeader set X_FORWARDED_PROTO https <Proxy *> Order allow,deny Allow from all </Proxy> <Directory /home/diaspora/diaspora/public> Options -Includes -ExecCGI Allow from all AllowOverride all Options +Indexes </Directory> DocumentRoot /home/diaspora/diaspora/public Basically it's working.

  • MediaWiki migrated from Tiger to Snow Leopard throwing an exceptions

    - by Matt S
    I had an old laptop running Mac OS X 10.4 with macports for web development: Apache 2, PHP 5.3.2, Mysql 5, etc. I got a new laptop running Mac OS X 10.6 and installed macports. I installed the same web development apps: Apache 2, PHP 5.3.2, Mysql 5, etc. All versions the same as my old laptop. A Mediawiki site (version 1.15) was copied over from my old system (via the Migration Assistant). Having a fresh Mysql setup, I dumped my old database and imported it on the new system. When I try to browse to mediawiki's "Special" pages, I get the following exception thrown: Invalid language code requested Backtrace: #0 /languages/Language.php(2539): Language::loadLocalisation(NULL) #1 /includes/MessageCache.php(846): Language::getFallbackFor(NULL) #2 /includes/MessageCache.php(821): MessageCache->processMessagesArray(Array, NULL) #3 /includes/GlobalFunctions.php(2901): MessageCache->loadMessagesFile('/Users/matt/Sit...', false) #4 /extensions/OpenID/OpenID.setup.php(181): wfLoadExtensionMessages('OpenID') #5 [internal function]: OpenIDLocalizedPageName(Array, 'en') #6 /includes/Hooks.php(117): call_user_func_array('OpenIDLocalized...', Array) #7 /languages/Language.php(1851): wfRunHooks('LanguageGetSpec...', Array) #8 /includes/SpecialPage.php(240): Language->getSpecialPageAliases() #9 /includes/SpecialPage.php(262): SpecialPage::initAliasList() #10 /includes/SpecialPage.php(406): SpecialPage::resolveAlias('UserLogin') #11 /includes/SpecialPage.php(507): SpecialPage::getPageByAlias('UserLogin') #12 /includes/Wiki.php(229): SpecialPage::executePath(Object(Title)) #13 /includes/Wiki.php(59): MediaWiki->initializeSpecialCases(Object(Title), Object(OutputPage), Object(WebRequest)) #14 /index.php(116): MediaWiki->initialize(Object(Title), NULL, Object(OutputPage), Object(User), Object(WebRequest)) #15 {main} I tried to step through Mediawiki's code, but it's a mess. There are global variables everywhere. If I change the code slightly to get around the exception, the page comes up blank and there are no errors (implying there are multiple problems). Anyone else get Mediawiki 1.15 working on OS X 10.6 with macports? Anything in the migration from Tiger that could cause a problem? Any clues where to look for answers?

  • Managing an application across multiple servers, or PXE vs cfEngine/Chef/Puppet

    - by matt
    We have an application that is running on a few (5 or so and will grow) boxes. The hardware is identical in all the machines, and ideally the software would be as well. I have been managing them by hand up until now, and don't want to anymore (static ip addresses, disabling all necessary services, installing required packages...) . Can anyone balance the pros and cons of the following options, or suggest something more intelligent? 1: Individually install centos on all the boxes and manage the configs with chef/cfengine/puppet. This would be good, as I have wanted an excuse to learn to use one of applications, but I don't know if this is actually the best solution. 2: Make one box perfect and image it. Serve the image over PXE and whenever I want to make modifications, I can just reboot the boxes from a new image. How do cluster guys normally handle things like having mac addresses in the /etc/sysconfig/network-scripts/ifcfg* files? We use infiniband as well, and it also refuses to start if the hwaddr is wrong. Can these be correctly generated at boot? I'm leaning towards the PXE solution, but I think monitoring with munin or nagios will be a little more complicated with this. Anyone have experience with this type of problem? All the servers have SSDs in them and are fast and powerful. Thanks, matt.

  • How can I associate html/htm files with Chrome in Windows 7 64 bit?

    - by matt
    I want Chrome to open all .html files. It is currently set as my default browser, however html files open in IE9. When I go to Control Panel\Programs\Default Programs\Set Associations I see that .html and .htm files are associated with IE. When I choose to change the default program it I'm presented with a list of programs but Chrome is not one of them. I browse to, and then select the Chrome.exe (C:\Users\Matt\AppData\Local\Google\Chrome\Application\chrome.exe) but it goes right back to IE. This is the first time I've seen anything like this. I'm running Windows 7 64 bit. I never had this problem on Windows 7 32 bit. Is this because Chrome by default installs in the User directory, not the Program Files directory? How can I fix these file associations? EDIT: It's not that things are reverting back to IE after associating them with Chrome. When I browse to Chrome in the file association window, and select it, it doesn't seem to take. It doesn't show Chrome in the list of programs despite pointing to the Chrome.exe location. I really think this has something to do with the fact that it doesn't install into the Program File Directory.

  • opath syntax to force dynamic distribution group field as numerical comparison? (Exchange 2010)

    - by Matt
    I'm upgrading a (working) query based group (Exchange 2003) to a new and 'improved' dynamic distribution group (2010). For better or worse, our company decided to store everyone's employee ID in the pager field, so it's easy to manipulate via ADUC. That employee number has significance, as all employees are in a certain range, and all contractors are in a very different range. Basically, the new opath syntax appears to be using string compare on my pager field, even though it's a number. Let's say my employee ID is 3004, well, it's "less than" 4 from a string check POV. Set-DynamicDistributionGroup -Identity "my-funky-new-group" -RecipientFilter "(pager -lt 4) -and (pager -like '*') -and (RecipientType -eq 'UserMailbox')" Shows up in EMC with this: ((((((Pager -lt '4') -and (Pager -ne $null))) -and (RecipientType -eq 'UserMailbox'))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox'))) This group should have max of 3 members right? Nope - I get a ton because of the string compare. I show up, and I'm in the 3000 range. Question: Anyone know a clever way to force this to be an integer check? The read-only LDAP filter on this group looks good, but of course it can't be edited. The LDAP representation (look ma, no quotes on the 4!) - Also interesting it sort of 'fills the' bed with the (pager=4) thing... (&(pager<=4)(!(pager=4))(pager=*)(objectClass=user)(objectCategory=person)(mailNickname=*)(msExchHomeServerName=*)(!(name=SystemMailbox{*))(!(name=CAS_{*))!(msExchRecipientTypeDetails=16777216))(!(msExchRecipientTypeDetails=536870912))(!(msExchRecipientTypeDetails=8388608))) If there is no solution, I suppose my recourse is either finding an unused field that actually will be treated as an integer, or most likely building this list with powershell every morning with my own automation - lame. I know of a few ways to fix this outside of the opath filter (designate "full-time" in another field, etc.), but would rather exchange do the lifting since this is the environment at the moment. Any insight would be great - thanks! Matt

  • Win7 System folder contains infinitely looping SYSTEM(!) directory

    - by Matt
    My Windows 7 Enterprise computer has been crashing fairly frequently recently, so I decided to boot up in safe mode and run the TrendMicro client I have installed. It froze about 10 minutes into the full system scan, so in the spirit of http://whathaveyoutried.com, I started scanning each folder individually. When I got to ProgramData, the AV failed with an uncaught exception. I then went down a level and tried scanning Application Data, which failed as well. Imagine my surprise when I open the folder just to see the same folder again! As far as I can tell, this folder loop continues indefinitely. (If you are trying to recreate this, keep in mind that ProgramData is a hidden folder.) I'm actually a bit concerned that these are system folders, as this is a brand-new computer with a clean installation. I guess I have three questions: Has anyone else seen/experienced this before? I'm running Win7 SP1. How do I fix this? I've run CHKDSK \F with no success (although it was incredibly slow). What are the ramifications of an infinitely recursive directory? Theoretically speaking, each link takes up memory, so shouldn't I have no space available on my hard drive? (I've got about 180GB left.) I noticed that the tree view on the left only shows the "linked folder" icon on the deeper folders--does this mean anything special? (I've circled the icons or lack thereof in red.) How can the OS even resolve this aberration? And above all, what would happen if I were to select "Expand all folders"??? :P Matt

  • For Programmers familiar with ACM API? Drawing Initials

    - by user71992
    I came across an exercise (in the book "The Art and Science of Java" by Eric Roberts) that requires using only GArc and GLine classes to create a lettering library which draws your initials on the canvas. This should be made independent of the GLabel class. I'd like to know the correct approach to use in solving this problem. I'm not sure what I have so far is good enough (I'm thinking it's too long). The questions requires that I use a good Top-Down approach.

  • Is there a way to hide the Primefaces fileUpload progress bar and buttons in advanced mode and auto mode?

    - by Joe Roberts
    Is there a way to hide the Primefaces fileUpload progress bar and buttons in advanced mode and auto mode? Here is the code that I am using: <p:fileUpload id="scriptUpload" widgetVar="importDevicesWidget" fileUploadListener="#{scriptUploadBean.handleFileUpload}" auto="true" label="Choose.." mode="advanced" update=":infoMessages" sizeLimit="8192" allowTypes="/(\.|\/)(txt)$/" onstart="clearInvalidFileMsg();$('#progress').show();" oncomplete="clearInvalidFileMsg();$('#progress').hide();importDevicesDialogWidget.hide()"/> The problem is that it makes no sense for the buttons that appear next to the progress bar for each file to be there as the mode is auto so the upload already started! Here is a screen shot:

  • how to re-enable default after doing event.preventDefault()

    - by Matt
    Hi, I know this exact question was asked here, but the answer didn't work for what I needed to do so I figured I'd give some example code and explain a bit... $(document).keypress( function (event) { // Pressing Up or Right: Advance to next video if (event.keyCode == 40 || event.keyCode == 39) { event.preventDefault(); $(".current").next().click(); } // Pressing Down or Left: Back to previous video else if (event.keyCode == 38 || event.keyCode == 37) { event.preventDefault(); $(".current").prev().click(); } } ); It basically disables the arrow keys to use them for something else, but doing: $(document).keypress(function () { }); doesn't enable the default function again... I need it to scroll the page without having to create a scroll function for it... Any ideas? Thanks, Matt

  • AuthSub token from Google/YouTube API is always returned as invalid

    - by Miriam Raphael Roberts
    Anyone out there have experience with the YouTube/Google API? I am trying to login to Google/Youtube using clientLogin, retrieve an AuthSub token, exchange it for a multi-session token and then use it in our upload form. Just a note that we are not going to have other users logging into our (secure) website, this is for our use only (no multi-users). We just want a way to upload videos to our YT account via our own website without having to login/upload to YouTube. Ultimately, everything is dependent on the first step. My AuthSub token is always being returned as invalid (Error '403'). All the steps I used are below with username/password changed. Anyone have an insight on why my AuthSub is always invalid? I am spending an enormous amount of time trying to get this to work.

  • In Asp.Net MVC 2 is there a better way to return 401 status codes without getting an auth redirect

    - by Greg Roberts
    I have a portion of my site that has a lightweight xml/json REST API. Most of my site is behind forms auth but only some of my API actions require authentication. I have a custom AuthorizeAttribute for my API that I use to check for certain permissions and when it fails it results in a 401. All is good, except since I'm using forms auth, Asp.net conveniently converts that into a 302 redirect to my login page. I've seen some previous questions that seem a bit hackish to either return a 403 instead or to put some logic in the global.asax protected void Application_EndRequest() that will essentially convert 302 to 401 where it meets whatever criteria. Previous Question Previous Question 2 What I'm doing now is sort of like one of the questions, but instead of checking the Application_EndRequest() for a 302 I make my authorize attribute return 666 which indicates to me that I need to set this to a 401. Here is my code: protected void Application_EndRequest() { if (Context.Response.StatusCode == MyAuthAttribute.AUTHORIZATION_FAILED_STATUS) { //check for 666 - status code of hidden 401 Context.Response.StatusCode = 401; } } Even though this works, my question is there something in Asp.net MVC 2 that would prevent me from having to do this? Or, in general is there a better way? I would think this would come up a lot for anyone doing REST api's or just people that do ajax requests in their controllers. The last thing you want is to do a request and get the content of a login page instead of json.

  • Modularizing web applications

    - by Matt
    Hey all, I was wondering how big companies tend to modularize components on their page. Facebook is a good example: There's a team working on Search that has its own CSS, javascript, html, etc.. There's a team working on the news feed that has its own CSS, javascript, html, etc... ... And the list goes on They cannot all be aware of what everyone is naming their div tags and whatnot, so what's the controller(?) doing to hook all these components in on the final page?? Note: This doesn't just apply to facebook - any company that has separate teams working on separate components has some logic that helps them out. EDIT: Thanks all for the responses, unfortunately I still haven't really found what I'm looking for - when you check out the source code (granted its minified), the divs have UIDs, my guess is that there is a compilation process that runs through and makes each of the components unique, renaming divs and css rules.. any ideas? Thanks all! Matt Mueller

  • Multiple update panels and multiple postbacks cause entire page to refresh...

    - by Matt
    I'm having the same problem I had yesterday... The solution Aristos provided helped solve the problem, but I have other places sending updatepanel postbacks causing the same problem. When an update panel is updated and another request for an update is called before it has a chance to render the first updates, the entire page refreshes instead of just the update panel. I used fiddler to see what was going on and here's what happens... If I wait for the request to return before doing another request I get this: 21443|updatePanel|dnn_ctr1107_CRM_SalesTool_LeadsUpdatePanel| But if I don't wait, I get this: 66|pageRedirect||http://mysite.com/salesdashboard.aspx| The code from the previous question is still the same except I added UpdateMode="Conditional" to the update panel. Any ideas? Or is the only solution to this making sure that 2+ updates for any number of update panels (as long as they're on the same page) never happen? Thanks, Matt

  • Printing PDFs Server-side using Acrobat Reader from ASP.NET

    - by Chris Roberts
    Hi, I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service. The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them). This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!? I know this is a FAR from ideal thing to be trying to do, but I haven't really got much choice! Any ideas would be greatly appreciated! Dim starter As ProcessStartInfo Dim Prc As Process ' Pass File Path And Arguments starter = New ProcessStartInfo("c:\program files\...\AcroRd32.exe", "/t ""test.pdf"" ""Printer""") starter.CreateNoWindow = True starter.RedirectStandardOutput = True starter.UseShellExecute = False ' Start Adobe Process Prc = New Process() Prc.StartInfo = starter Prc.Start()

  • Sharepoint Web Part OnPreRender PostBack Dynamic TextBoxes Not Accessible In Button Handler

    - by Matt
    I have a custom webpart which extends System.Web.UI.WebControls.WebPart and implements an EditorPart. I have all the static controls being added in the overridden CreateChildControls method as I know this makes them persistent across PostBacks. However, I have some TextBoxes being added in the overridden OnPreRender method because the actual TextBoxes that I add depend upon the data returned from a Web Service which I am calling in OnPreRender. The Web Service has to be called in OnPreRender because I need some of the Property values that are set in the EditorPart. If I build this logic into the CreateChildControls method, obviously the data is not available on first PostBack after an edit is applied because the PostBack events are restored after CreateChildControls. This means the page has to be posted twice before the data is refreshed and that is just cludgy. How can make these TextBoxes along with their entered text values persistent across PostBacks so that I can access them in the button handler? Thanks for any help, Matt

  • Delphi 2010 Datasnap - Design Query

    - by Matt
    I am investigating moving a thick client SQL based Delphi application to Multi Tier thin clients, and have been looking at using Datasnap in Delphi 2010. I have worked through the White Paper written by Bob Swart and extended this further. My main question really is that I want to make the server side efficient in terms of connections and SQL Queries due to multiple queries being run and remaining open at the same time to interrogate data, can anyone point me in a direction for guidance on how to design a real world Datasnap Server application, as the demo's don't go into enough detail.

  • Sub-classing TreeView in C# WinForms for mouse over tool tips

    - by Matt
    Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one. Thanks Matt

  • "Quoted-printable line longer than 76 chars" warning when sending HTML E-Mail

    Hi, I have written some code in my VB.NET application to send an HTML e-mail (in this case, a lost password reminder). When I test the e-mail, it gets eaten by my spam filter. One of the things that it's scoring badly on is because of the following problem: MIME_QP_LONG_LINE RAW: Quoted-printable line longer than 76 chars I've been through the source of the e-mail, and I've broken each line longer than 76 characters into two lines with a CR+LF in between, but that hasn't fixed the problem. Can anyone point me in the right direction? Thanks!

My code is as follows: #lang racket/gui (require racket/gui/base) (define floor (make-object bitmap% "C:\\floortile.png")) (define pixels (make-bytes (* 32 32 4))) (send floor get-argb-pixels 0 0 32 32 pixels) After executing the code I was expecting a series of 8 bit values to be contained within pixels.
