  • Why won't xattr PECL extension build on 12.10?

    - by Dan Jones
    I was using the xattr pecl extension in 12.04 (in fact, I think since 10.04) without problem. Not surprisingly, I had to reinstall it after upgrading to 12.10 because of the new version of PHP. But now it fails to build, and I can't figure out why. Other PECL extensions have built fine. And I have libattr1 and libattr1-dev installed. Here's the output from the build: downloading xattr-1.1.0.tgz ...

Does this just not work properly in 12.10? That would be a big problem for me.

  • Can&rsquo;t eject external USB or Firewire drive in Windows 7

    - by Kelly Jones
    As a SharePoint developer, I work a lot with Virtual Machines (presently using Windows Virtual PC, with Windows 7).  I’m using these VMs with my laptop, and in order to get better performance, I’ve moved them to external hard drives.  (These drives have faster RPMs, larger caches, and a larger capacity, than the internal drive.)  I have one large external drive at home, another similar drive at the office, and a small, slow portable drive that I carry with me. So, at the end of each day at the office, I copy the files from the external drive to my portable drive and then once I get home, I copy them from the portable to the larger external drive I leave at home.  I do this for a couple of reasons: so I can work at home and secondly, so I have backup copies.  (Often, I feel like I’m in the movie “Office Space” when copying the files before I leave the office). Anyway, after the files are copied, I safely eject the external drives, and then hibernate my laptop.  I’ve been doing this for over a year now, but within the last couple of months I started to have issues disconnecting the drives.  Intermittently, some application/process would have a lock on some file on the drive that would keep Windows from safely ejecting it. After looking into it, I found that it was actually the Windows search service that was accessing the drive! Since I wasn’t using Windows search to look for stuff on these drives, I removed them as locations to index. To do this in Windows 7, you need to go to Indexing Options (just type “Indexing” into the search box in the Start menu…).  One of the choices displayed will then be Indexing Options, so click on it and you should then see a window similar to this:   Click on the Modify button and you’ll see this window: Notice the different drives listed above.  My “FreeAgent XTreme (F:)” drive was checked for some reason, which was causing the indexing service to scan the drive looking for new files to make available in the search results.  Ever since I unchecked this box, I’ve been able to safely eject the drive.

  • Integrating Windows Form Click Once Application into SharePoint 2007 &ndash; Part 1 of 2

    - by Kelly Jones
    Last year, I had the opportunity to build a solution that involved integrating a Windows Form application into a SharePoint 2007 (WSS version 3.0). In this post, I’ll layout our architecture thinking and in part two, I’ll describe the technical details. Business Case Our challenge was this: we needed an easy way for a small group of our users to upload documents, in batches.  They also needed to quickly set the meta data values, as well as set security on individual files. Using the out of the box uploads just didn’t fit.  The single file upload allows set the meta data, but our users would be uploading dozens of files.  The multiple upload would allow our users to upload batches of files, but it doesn’t allow them to set the meta data during upload.  Also, neither upload method allows the users to set the permissions on the file. Our Solution We looked into building a web control of some kind, but ruled that out due to security complexities (if I remember correctly).  Another option would have been using a technology like Silverlight (or Flash?), but our team didn’t have the skills necessary to build with these. So, after looking at what was technically possible, and also what skills our team had, we settled on a Windows Form application.  We also decided to deliver it to the clients via Click Once, so we would have the ability to easily update the application in the future. Lessons Learned After deploying our solution, we’ve learned a few lessons.  First, you’ll need to have the .Net Framework installed on the client computers.  We knew this, but we still ran into issues making sure our users had the proper framework version installed.  Second, we had issues with authentication.  Our issues were due to our testing domain being a separate Active Directory domain from the domain that our end users and their workstations were members of.  (See my earlier post about Clearing Saved Passwords for the fix to our problem). Our third issue was how we dealt with uploading files that were named the same.  Our application would replace the existing file with the new file, which is the way we expected it to work.  However, our users wanted to upload weekly reports, named the same as the previous week.  We solved this by using folders within the document library to keep the sets of reports separate from previous weeks. One last thing to consider before implementing a solution like this, is what browsers and platforms your users will be working from.  We only needed to support IE and Windows, which works fine.  However, if you need to support Firefox, there are add-ons that allow Click Once to work with Firefox.  This is still a Windows only solution though.  In order to support Macs, you’d have to focus on either browser techniques (AJAX?) or Silverlight/Flash. Summary Our users are happy with the Click Once app.  It allowed them to move all of their content to our SharePoint site in under a couple hours, which they were thrilled with.  We’re happy because we can easily deploy updates, our development time was small, and we met all of our business requirements.

  • Can&rsquo;t install Transport HUB in Exchange 2010

    - by Kelly Jones
    When building my latest SharePoint 2010 demo virtual machines, I decided to try installing Exchange 2010 as well.  Now, I’m not an Exchange admin, but I thought “how hard can this be?”  Well, a little more than I thought. Pretty early during the install, I got an error saying that it couldn’t “install Transport HUB”.  I double checked that my VM was meeting all of the requirements, both hardware and software, and everything looked fine. After much researching, it turns out that the error was caused by not having IPv6 enabled on the network adapter inside the virtual machine.  I had turned it off because I thought I wouldn’t need it.  I guess Exchange 2010 does.

  • Twitter API Voting System

    - by Richard Jones
    So I blatantly got this idea from the MIX 10 event. At MIX they held a rockband talent competition type thing (I’m not quite sure of all the details).    But the interesting part for me is how they collected votes. They used Twitter (what else, when you have a few thousand geeks available to you). The basic idea was that you tweeted your vote with a # tag, i.e #ROCKBANDVOTE vote Richard How cool….    So the question is how do you write something to collate and count all the votes?   Time to press the magic Visual Studio new Project button… Twitter has a really nice API that can be invoked from .NET.   This is the snippet of code that will search for any given phrase i.e #ROCKBANDVOTE   public static XmlDocument GetSearchResults(string searchfor) { return GetSearchResults(searchfor, ""); }   public static XmlDocument GetSearchResults(string searchfor, string sinceid) { XmlDocument retdoc = new XmlDocument();   try { string url = "http://search.twitter.com/search.atom?&q=" + searchfor; if (sinceid.Length > 0) url += "since_id=" + sinceid; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; WebResponse res = request.GetResponse(); retdoc.Load(res.GetResponseStream()); res.Close();   } catch { } return retdoc; } } I’ve got two overloads, that optionally let you pass in the last ID to look for as well as what you want to search for. Note that Twitter rate limits the amount of requests you can send,  see http://apiwiki.twitter.com/Rate-limiting So realistically I wanted my app to run every hour or so and only pull out results that haven’t been received before (hence the overload to pass in the sinceid parameter). I’ll post the code when finished that parses the returned XML.

  • Updating a SharePoint master page via a solution (WSP)

    - by Kelly Jones
    In my last blog post, I wrote how to deploy a SharePoint theme using Features and a solution package.  As promised in that post, here is how to update an already deployed master page. There are several ways to update a master page in SharePoint.  You could upload a new version to the master page gallery, or you could upload a new master page to the gallery, and then set the site to use this new page.  Manually uploading your master page to the master page gallery might be the best option, depending on your environment.  For my client, I did these steps in code, which is what they preferred. (Image courtesy of: http://www.joiningdots.net/blog/2007/08/sharepoint-and-quick-launch.html ) Before you decide which method you need to use, take a look at your existing pages.  Are they using the SharePoint dynamic token or the static token for the master page reference?  The wha, huh? SO, there are four ways to tell an .aspx page hosted in SharePoint which master page it should use: “~masterurl/default.master” – tells the page to use the default.master property of the site “~masterurl/custom.master” – tells the page to use the custom.master property of the site “~site/default.master” – tells the page to use the file named “default.master” in the site’s master page gallery “~sitecollection/default.master” – tells the page to use the file named “default.master” in the site collection’s master page gallery For more information about these tokens, take a look at this article on MSDN. Once you determine which token your existing pages are pointed to, then you know which file you need to update.  So, if the ~masterurl tokens are used, then you upload a new master page, either replacing the existing one or adding another one to the gallery.  If you’ve uploaded a new file with a new name, you’ll just need to set it as the master page either through the UI (MOSS only) or through code (MOSS or WSS Feature receiver code – or using SharePoint Designer). If the ~site or ~sitecollection tokens were used, then you’re limited to either replacing the existing master page, or editing all of your existing pages to point to another master page.  In most cases, it probably makes sense to just replace the master page. For my project, I’m working with WSS and the existing pages are set to the ~sitecollection token.  Based on this, I decided to just upload a new version of the existing master page (and not modify the dozens of existing pages). Also, since my client prefers Features and solutions, I created a master page Feature and a corresponding Feature Receiver.  For information on creating the elements and feature files, check out this post: http://sharepointmagazine.net/technical/development/deploying-the-master-page . This works fine, unless you are overwriting an existing master page, which was my case.  You’ll run into errors because the master page file needs to be checked out, replaced, and then checked in.  I wrote code in my Feature Activated event handler to accomplish these steps. Here are the steps necessary in code: Get the file name from the elements file of the Feature Check out the file from the master page gallery Upload the file to the master page gallery Check in the file to the master page gallery Here’s the code in my Feature Receiver: 1: public override void FeatureActivated(SPFeatureReceiverProperties properties) 2: { 3: try 4: { 5:   6: SPElementDefinitionCollection col = properties.Definition.GetElementDefinitions(System.Globalization.CultureInfo.CurrentCulture); 7:   8: using (SPWeb curweb = GetCurWeb(properties)) 9: { 10: foreach (SPElementDefinition ele in col) 11: { 12: if (string.Compare(ele.ElementType, "Module", true) == 0) 13: { 14: // <Module Name="DefaultMasterPage" List="116" Url="_catalogs/masterpage" RootWebOnly="FALSE"> 15: // <File Url="myMaster.master" Type="GhostableInLibrary" IgnoreIfAlreadyExists="TRUE" 16: // Path="MasterPages/myMaster.master" /> 17: // </Module> 18: string Url = ele.XmlDefinition.Attributes["Url"].Value; 19: foreach (System.Xml.XmlNode file in ele.XmlDefinition.ChildNodes) 20: { 21: string Url2 = file.Attributes["Url"].Value; 22: string Path = file.Attributes["Path"].Value; 23: string fileType = file.Attributes["Type"].Value; 24:   25: if (string.Compare(fileType, "GhostableInLibrary", true) == 0) 26: { 27: //Check out file in document library 28: SPFile existingFile = curweb.GetFile(Url + "/" + Url2); 29:   30: if (existingFile != null) 31: { 32: if (existingFile.CheckOutStatus != SPFile.SPCheckOutStatus.None) 33: { 34: throw new Exception("The master page file is already checked out. Please make sure the master page file is checked in, before activating this feature."); 35: } 36: else 37: { 38: existingFile.CheckOut(); 39: existingFile.Update(); 40: } 41: } 42:   43: //Upload file to document library 44: string filePath = System.IO.Path.Combine(properties.Definition.RootDirectory, Path); 45: string fileName = System.IO.Path.GetFileName(filePath); 46: char slash = Convert.ToChar("/"); 47: string[] folders = existingFile.ParentFolder.Url.Split(slash); 48:   49: if (folders.Length > 2) 50: { 51: Logger.logMessage("More than two folders were detected in the library path for the master page. Only two are supported.", 52: Logger.LogEntryType.Information); //custom logging component 53: } 54:   55: SPFolder myLibrary = curweb.Folders[folders[0]].SubFolders[folders[1]]; 56:   57: FileStream fs = File.OpenRead(filePath); 58:   59: SPFile newFile = myLibrary.Files.Add(fileName, fs, true); 60:   61: myLibrary.Update(); 62: newFile.CheckIn("Updated by Feature", SPCheckinType.MajorCheckIn); 63: newFile.Update(); 64: } 65: } 66: } 67: } 68: } 69: } 70: catch (Exception ex) 71: { 72: string msg = "Error occurred during feature activation"; 73: Logger.logException(ex, msg, ""); 74: } 75:   76: } 77:   78: /// <summary> 79: /// Using a Feature's properties, get a reference to the Current Web 80: /// </summary> 81: /// <param name="properties"></param> 82: public SPWeb GetCurWeb(SPFeatureReceiverProperties properties) 83: { 84: SPWeb curweb; 85:   86: //Check if the parent of the web is a site or a web 87: if (properties != null && properties.Feature.Parent.GetType().ToString() == "Microsoft.SharePoint.SPWeb") 88: { 89:   90: //Get web from parent 91: curweb = (SPWeb)properties.Feature.Parent; 92: 93: } 94: else 95: { 96: //Get web from Site 97: using (SPSite cursite = (SPSite)properties.Feature.Parent) 98: { 99: curweb = (SPWeb)cursite.OpenWeb(); 100: } 101: } 102:   103: return curweb; 104: } This did the trick.  It allowed me to update my existing master page, through an easily repeatable process (which is great when you are working with more than one environment and what to do things like TEST it!).  I did run into what I would classify as a strange issue with one of my subsites, but that’s the topic for another blog post.

  • Deploying a SharePoint 2007 theme using Features

    - by Kelly Jones
    I recently had a requirement to update the branding on an existing Windows SharePoint Services (WSS version 3.0) site.  I needed to update the theme, along with the master page.  An additional requirement is that my client likes to have all changes bundled up in SharePoint solutions.  This makes it much easier to move code from dev to test to prod and more importantly, makes it easier to undo code migrations if any issues would arise (I agree with this approach). Updating the theme was easy enough.  I created a new theme, along with a two new features.  The first feature, scoped at the farm level, deploys the theme, adding it to the spthemes.xml file (in the 12 hive –> \Template\layouts\1033 folder).  Here’s the method that I call from the feature activated event: private static void AddThemeToSpThemes(string id, string name, string description, string thumbnail, string preview, SPFeatureReceiverProperties properties) { XmlDocument spThemes = new XmlDocument(); //use GetGenericSetupPath to find the 12 hive folder string spThemesPath = SPUtility.GetGenericSetupPath(@"TEMPLATE\LAYOUTS\1033\spThemes.xml"); //load the spthemes file into our xmldocument, since it is just xml spThemes.Load(spThemesPath); XmlNode root = spThemes.DocumentElement; //search the themes file to see if our theme is already added bool found = false; foreach (XmlNode node in root.ChildNodes) { foreach (XmlNode prop in node.ChildNodes) { if (prop.Name.Equals("TemplateID")) { if (prop.InnerText.Equals(id)) { found = true; break; } } } if (found) { break; } } if (!found) //theme not found, so add it { //This is what we need to add: // <Templates> // <TemplateID>ThemeName</TemplateID> // <DisplayName>Theme Display Name</DisplayName> // <Description>My theme description</Description> // <Thumbnail>images/mythemethumb.gif</Thumbnail> // <Preview>images/mythemepreview.gif</Preview> // </Templates> StringBuilder sb = new StringBuilder(); sb.Append("<Templates><TemplateID>"); sb.Append(id); sb.Append("</TemplateID><DisplayName>"); sb.Append(name); sb.Append("</DisplayName><Description>"); sb.Append(description); sb.Append("</Description><Thumbnail>"); sb.Append(thumbnail); sb.Append("</Thumbnail><Preview>"); sb.Append(preview); sb.Append("</Preview></Templates>"); root.CreateNavigator().AppendChild(sb.ToString()); spThemes.Save(spThemesPath); } } Just as important, is the code that removes the theme when the feature is deactivated: private static void RemoveThemeFromSpThemes(string id) { XmlDocument spThemes = new XmlDocument(); string spThemesPath = HostingEnvironment.MapPath("/_layouts/") + @"1033\spThemes.xml"; spThemes.Load(spThemesPath); XmlNode root = spThemes.DocumentElement; foreach (XmlNode node in root.ChildNodes) { foreach (XmlNode prop in node.ChildNodes) { if (prop.Name.Equals("TemplateID")) { if (prop.InnerText.Equals(id)) { root.RemoveChild(node); spThemes.Save(spThemesPath); break; } } } } } So, that takes care of deploying the theme.  In order to apply the theme to the web, my activate feature method looks like this: public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { using (SPWeb curweb = (SPWeb)properties.Feature.Parent) { curweb.ApplyTheme("myThemeName"); curweb.Update(); } } Deactivating is just as simple: public override void FeatureDeactivating(SPFeatureReceiverProperties properties) { using (SPWeb curweb = (SPWeb)properties.Feature.Parent) { curweb.ApplyTheme("none"); curweb.Update(); } } Ok, that’s the code necessary to deploy, apply, un-apply, and retract the theme.  Also, the solution (WSP file) contains the actual theme files. SO, next is the master page, which I’ll cover in my next blog post.

  • Passwords in WP7

    - by Richard Jones
    I’ve been trying to protect password entry boxes in Windows Phone 7 (on the emulator) SilverLight supports inputscopes to achieve just this. Peter Foot blogged about this too.  http://mobileworld.appamundi.com/blogs/peterfoot/archive/2010/03/22/windows-phone-7-input.aspx?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+PeterFoot+%28Peter+Foot%29 It seems that password inputscope doesn’t quite work yet, please don’t pull your hair out like I just did..   This is the code I was using. <TextBox Height="31" HorizontalAlignment="Left" Margin="240,99,0,0" Name="tbuser" Text="" VerticalAlignment="Top" Width="181" TabIndex="1" >                <TextBox.InputScope>                    <InputScope>                        <InputScope.Names>                            <InputScopeName NameValue="TelephoneNumber"/>                        </InputScope.Names>                    </InputScope>                </TextBox.InputScope>            </TextBox>   Other inputscopes like Telephonenumber work great.  Thought I would blog this to save you from a small bit of pain.

  • PHP Development Environment (Host: Windows 7, Guest: Ubuntu)

    - by Kristian Leiws Jones
    Since editing files live from a remote server slows down development. I use XAMPP on windows to develop then run the web app's on a Linux server. However to avoid environment dependencies I'd like to mirror the live environment and the development environments. What I'm asking is running development server on Ubuntu inside VirtualBox whilst editing the source files via ftp/Dreamweaver is a good idea? If so, and I wanted to view the local website on the host OS (windows) how would I do this? does the guest OS have a LAN/Local IP address? I notice on windows "ipconfig /all" there are "tunneling" adapters which I assume is for VirtualBox, so I guess the guest OS has the same LAN/Local IP address? if so how would I view the websites hosted on the guest OS on the host OS? I'd also need to host FTP server on guest OS. Note: I need windows! I would love to use Linux all the way -.-

  • Access denied error when adding new server to existing SharePoint 2007 Farm

    - by Kelly Jones
    I recently got an error when adding a new SharePoint 2007 (SP2) server to our existing MOSS farm.  I had run the installation fine, and was walking through the SharePoint Configuration Wizard, when I got an error on step 2: “Resource retrieved id PostSetupConfigurationFailedEventLog is Configuration of SharePoint Products and Technologies failed.” I searched the net, but didn’t really find anything. I then remembered that I had forgotten to run the latest SharePoint updates (for us, the latest applied was December 2009).  I installed the WSS update, and then the MOSS update and both worked fine.  I then ran the Configuration wizard again and it worked without any errors.

  • How&rsquo;s your Momma an&rsquo; them?

    - by Bill Jones Jr.
    When a Southern “boy” like me sees somebody that used to be, or should be, a close friend or relative that they haven’t seen in a long time, that’s a typical greeting.  Come to think of it, we were often related to close friends. So “back in the day”, we not only knew people but everybody close to them.  When I started driving, my Dad told me to always drive carefully in Polk county.  He said if I ran into anybody there, it was likely they would be related or close family friends. Not so much any more… the cities have gotten bigger and more people come south and stay.  One of the curses of air conditioning I guess. Anyway, it’s been a while.  So “How’s your Momma and them”?  Have you been waiting for me to blog again?  Too bad, I’m back anyway <smile>. Here in Charlotte we just had another great code camp.  The Enterprise Developers Guild is going strong, thanks to the help of a lot of dedicated people.  Mark Wilson, Brian Gough, Syl Walker, Ghayth Hilal, Alberto Botero, Dan Thyer, Jean Doiron, Matt Duffield all come to mind.  Plus all the regulars who volunteer for every special event we have. Brian Gough put on a successful SharePoint Saturday.  Rafael Salas and our friends at the local Pass SQL group had a great SQL Saturday.  Brian Hitney and Glen Gordon keep on doing their usual great job for developers in the southeast as our local Microsoft reps. Since my last post, I have the honor of being designated the INetA Membership Mentor for Georgia in addition to mentoring the groups in the Carolinas for the past several years.  Georgia could be a really good thing since my wife likes shopping in Atlanta, not to mention how much we both like Georgia in general.  As I recall, my Momma had people in Georgia.  Wonder how their “Mommas an’ them” are doing?   Bill J

  • Corrupted Views when migrating document libraries from SharePoint 2003 to 2007

    - by Kelly Jones
    A coworker of mine ran into this error recently, while migrating a document library from SharePoint 2003 to 2007: “A WebPartZone can only exist on a page which contains a SPWebPartManager. The SPWebPartManager must be placed before any WebPartZones on the page.” He saw this when he tried to see the All Documents view for the library. After looking into it, we figured out what had happened.  He was migrating documents using the Explorer View in SharePoint.  He had copied the contents of the library from one server (a remote server that we didn’t have administrative access to) to his desktop.  He then opened an Explorer View of the new library and copied the files to it.  Well, it turns out he had copied the hidden “Forms” folder, which contained the files necessary to display the different views for the library. (He had set his explorer to show hidden files, which made them visible.) So, he had copied the 2003 forms to the 2007 library, which are incompatible. We fixed it, by simply deleting the new document library, recreating it, and then copied everything except that hidden Forms folder.  Another option might have been to create a new document library on 2007, and copy the Forms folder from it to the broken library.  Since we didn’t need to save anything in the broken BTW, I confirmed my suspicion with this blog post: http://palmettotq.com/blog/?p=54

  • SharePoint 2007 Parser Error after updating master page

    - by Kelly Jones
    A few weeks ago I was updating the master page for a SharePoint 2007 (WSS) site.  The client wanted the site updated to reflect the new look and feel that is being applied to another set of sites in the organization. I created a new theme and master page, which I already wrote about here and here.  It worked well, except for a few pages on a subsite.  On those pages, I got the following error: Server Error in '/' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Code blocks are not allowed in this file.   I decided to go comb through my new master page and compare it to the existing master page that was already working.  After going through them line by line several times, I had no clue what would be causing the error because they were basically the same! It turns out, it was a combination of two things.  First, on a few of the pages in the site, there was some include code (basically an <% EVAL()%> snippet).  This was the code that was triggering my error “Code blocks are not allowed in this file”. However, this code was working fine with the previous master page. I decided to then try doing a full deployment of the site with the new master page, and it worked fine!  Apparently, if the master page is deployed using a Feature, then it is granted permission to allow code blocks, but if you upload pages either using web UI or SharePoint Designer, then the pages won’t be able to use code blocks. I haven’t been able to pin down the rules or official info about this, but I thought others might find it useful anyway.

  • Netretail's online retail operation benefits from personal contact

    - by christopher.jones
    Hot on oracle.com is a snapshot of Netretail Holding B.V. profiling their use of PHP and Oracle technology such as Oracle RAC cluster database to become a leading online retailer across Central and Eastern Europe. We've also just refreshed our key PHP Scalability and High Availability whitepaper which talks about connection pooling (DRCP) and Fast Application Notification (FAN). We brought it up to date for 11gR2 and PHP 5.3. It now includes the new 11gR2 V$CPOOL_CONN_INFO view, the new columns for DBA_CPOOL_INFO, information about LOGOFF triggers, and information about the support for Client Result Caching with DRCP. Back to Netretail. Two of their secrets to success are keeping technically up to date, and networking. That is, networking in the business sense. I had the pleasure of meeting Michal Táborský (@whizz), the Chief System Architect, when he was in California for a Velocity conference. Michal took time to visit Oracle HQ and talk with our developers about his then current architecture and future needs. I also met his manager at last year's Oracle OpenWorld conference. Having built up a relationship with us, Netretail now has access to Oracle Development staff. While this will never bypass Oracle Support (which have tools, systems etc that are needed and useful for resolving issues), it makes communication easier for some classes of questions. It helps discussions that will let us improve Oracle products, and make Netretail stronger. I like this. And there's no reason why you can't talk with us too. You know where to email me.

  • Can't complete dropbox installation from behind proxy

    - by Mark Jones
    Problem: My PC on campus sits behind a proxy (requiring authentication) and I can't setup Dropbox. I am convinced that this is a proxy issue as I can't setup Ubuntu one either (but I don't use Ubuntu One so that is not a problem). I have looked at the Ubuntu One fix but it seems to be to modify settings explicitly related to Ubuntu One. I can install the nautilus-dropbox package (compiled from source and from .deb package from website and from software centre) but once I click OK from the "Dropbox Installation" dialog box (prompting me to download the proprietary daemon) the installation just freezes with the OK button pressed. When I look at its process in System Monitor its waiting channel is inet_wait_for_connect. I have set the following proxy directives thus far: Added mj22:**@proxy.waikato.ac.nz:80 information to network proxy settings under network in settings. Added http_host and http_port variables under gconf-editor-system-proxy Added 'host', 'authentication_password' 'authentication_user' and ticked 'user authentication' and 'use_http_proxy' under gconf-editor-system-http_proxy Added export http_proxy="http://mj22:**@proxy.waikato.ac.nz:80/" to /etc/bash.bashrc Added Acquire::http::proxy "http://mj22:**@proxy.waikato.ac.nz:80/"; to /etc/apt/apt.conf (which is what I imagine is letting Software Center retrieve packages). (where ** is my password) I have also added the equivalent ftp and https lines for the above entries. I get the internet fine and Software Centre can download packages but thats it. Related issues: The software centre can't fetch reviews (but can download packages). When trying to add an online account in Gnome 3 a dialog pop up appears with "Error getting a Request Token: Cannot connect to proxy (proxy.waikato.ac.nz)" Updates: After some time (10mins ish) Dropbox shows an error dialog box that reads: Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set you http_proxy environment variable. Is there a way I can see what environment variables are currently set?

  • Design Pattern Advice for Bluetooth App for Android

    - by Aimee Jones
    I’m looking for some advice on which patterns would apply to some of my work. I’m planning on doing a project as part of my college work and I need a bit of help. My main project is to make a basic Android bluetooth tracking system where the fixed locations of bluetooth dongles are mapped onto a map of a building. So my android app will regularly scan for nearby dongles and triangulate its location based on signal strength. The dongles location would be saved to a database along with their mac addresses to differentiate between them. The android phones location will then be sent to a server. This information will be used to show the phone’s location on a map of the building, or map of a route taken, on a website. My side project is to choose a suitable design pattern that could be implemented in this main project. I’m still a bit new to design patterns and am finding it hard to get my head around ones that may be suitable. I’ve heard maybe some that are aimed at web applications for the server side of things may be appropriate. My research so far is leading me to the following: Navigation Strategy Pattern Observer Pattern Command Pattern News Design Pattern Any advice would be a great help! Thanks

To quickly review, we needed a way for our business users to upload documents to a SharePoint 2007 document library in mass, set the meta data, set the permissions per document, and to do so easily. Let’s look at the pieces that make up our solution.  First, we have the Windows Form application.  This app is deployed using Click Once and calls SharePoint web services in order to upload files and then calls web services to set the meta data (SharePoint columns and permissions).  Second, we have a custom action.  The custom action is responsible for providing our users a link that will launch the Windows app, as well as passing values to it via the query string.  And lastly, we have the web services that the Windows Form application calls.  For our solution, we used both out of the box web services and a custom web service in order to set the column values in the document library as well as the permissions on the documents. Now, let’s look at the technical details of each of these pieces.  (All of the code is downloadable from here: )   Windows Form application deployed via Click Once The Windows Form application, called “Custom Upload”, has just a few classes in it: Custom Upload -- the form FileList.xsd -- the dataset used to track the names of the files and their meta data values SharePointUpload -- this class handles uploading the file SharePointUpload uses an HttpWebRequest to transfer the file to the web server. We had to change this code from a WebClient object to the HttpWebRequest object, because we needed to be able to set the time out value.  public bool UploadDocument(string localFilename, string remoteFilename) { bool result = true; //Need to use an HttpWebRequest object instead of a WebClient object // so we can set the timeout (WebClient doesn't allow you to set the timeout!) HttpWebRequest req = (HttpWebRequest)WebRequest.Create(remoteFilename); try { req.Method = "PUT"; req.Timeout = 60 * 1000; //convert seconds to milliseconds req.AllowWriteStreamBuffering = true; req.Credentials = System.Net.CredentialCache.DefaultCredentials; req.SendChunked = false; req.KeepAlive = true; Stream reqStream = req.GetRequestStream(); FileStream rdr = new FileStream(localFilename, FileMode.Open, FileAccess.Read); byte[] inData = new byte[4096]; int bytesRead = rdr.Read(inData, 0, inData.Length); while (bytesRead > 0) { reqStream.Write(inData, 0, bytesRead); bytesRead = rdr.Read(inData, 0, inData.Length); } reqStream.Close(); rdr.Close(); System.Net.HttpWebResponse response = (HttpWebResponse)req.GetResponse(); if (response.StatusCode != HttpStatusCode.OK && response.StatusCode != HttpStatusCode.Created) { String msg = String.Format("An error occurred while uploading this file: {0}\n\nError response code: {1}", System.IO.Path.GetFileName(localFilename), response.StatusCode.ToString()); LogWarning(msg, "2ACFFCCA-59BA-40c8-A9AB-05FA3331D223"); result = false; } } catch (Exception ex) { LogException(ex, "{E9D62A93-D298-470d-A6BA-19AAB237978A}"); result = false; } return result; } The class also contains the LogException() and LogWarning() methods. When the application is launched, it parses the query string for some initial values.  The query string looks like this: string queryString = "Srv=clickonce&Sec=N&Doc=DMI&SiteName=&Speed=128000&Max=50"; This Srv is the path to the server (my Virtual Machine is name “clickonce”), the Sec is short for security – meaning HTTPS or HTTP, the Doc is the shortcut for which document library to use, and SiteName is the name of the SharePoint site.  Speed is used to calculate an estimate for download speed for each file.  We added this so our users uploading documents would realize how long it might take for clients in remote locations (using slow WAN connections) to download the documents. The last value, Max, is the maximum size that the SharePoint site will allow documents to be.  This allowed us to give users a warning that a file is too large before we even attempt to upload it. Another critical piece is the meta data collection.  We organized our site using SharePoint content types, so when the app loads, it gets a list of the document library’s content types.  The user then select one of the content types from the drop down list, and then we query SharePoint to get a list of the fields that make up that content type.  We used both an out of the box web service, and one that we custom built, in order to get these values. Once we have the content type fields, we then add controls to the form.  Which type of control we add depends on the data type of the field.  (DateTime pickers for date/time fields, etc)  We didn’t write code to cover every data type, since we were working with a limited set of content types and field data types. Here’s a screen shot of the Form, before and after someone has selected the content types and our code has added the custom controls:     The other piece of meta data we collect is the in the upper right corner of the app, “Users with access”.  This box lists the different SharePoint Groups that we have set up and by checking the boxes, the user can set the permissions on the uploaded documents. All of this meta data is collected and submitted to our custom web service, which then sets the values on the documents on the list.  We’ll look at these web services in a future post. In the next post, we’ll walk through the Custom Action we built.

    It's been an eventful day here at Microsoft DevDays 2010, and the show hasn't even officially started! First item of business is to get to a hotel for rest and get some great food-not necessarily in that order. My flight was as good as one can expect- the guy next to me, Jim Anderson, was affable but not overly chatty, and he's a soundman on European tour with The Sonics. Jim was the house-sound guy for the Crocodile Caf for many years, and it was great to talk to a guy who loves audio like I do....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
