• VS2010: Warning on add project reference to Silverlight project from .NET project

  - by nlawalker

  In VS2010, Silverlight 4, .NET 4, I've got a WCF service and a Silverlight app, and Silverlight is accessing the class not with Add Service Reference but by sharing the contract. Naturally, this means I have the contract in a Silverlight class library, and the service has a project reference to that library. Strangely, this results in a /!\ icon on the reference, and a warning: The project 'SilverlightClassLibrary1' cannot be referenced. The referenced project is targeted to a different framework family (Silverlight) However, the reference works fine (I can use the interface in my Silverlight app) and builds fine. Is this a bug? My guess is yes, since the warning is lying and also goes away if you add an assembly reference instead of a project reference. I filed a bug and there's more info here as well.

• Android: onKeyDown() problem

  - by niko

  Hi, I would like to create a photo/video capture application. I have created a CaptureView class which extends SurfaceView and placed it in the main form. The main form's activity has onCreateOptionsMenu() method which creates a menu. The menu worked fine but then I tried to implement a method onKeyDown: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_CAMERA: videoPreview.TakePicture(); return true; } } return super.onKeyDown(keyCode, event); } The menu doesn't appear anymore and the method doesn't catch onKeyDown event. Does anyone know what could be the reason for this issue? Thanks!

• UITableView Core Data reordering

  - by PCWiz

  I know this question has been asked before, and I took a look at the answer to this question. However, I'm still confused as to how to implement reordering with a UITableView in a Core Data project. What I know is that I need to have a "displayOrder" attribute in my Entity to track the order of items, and I need to enumerate through all the objects in the fetched results and set their displayOrder attribute. In the given code in the question I linked to, the table view delegate method calls a method like this [self FF_fetchResults];, and the code for that method is not given so its hard to tell what exactly it is. Is there any sample code that demonstrates this? That would be simpler to look at than sharing large chunks of code. Thanks

• Android: Set a random image using setImageResource

  - by Tom Jones

  I need a help with setting a random image using setImageResource method. In the drawable folder, I have a jpeg file named photo0.jpg, photo1.jpg...photo99.jpg. And the following code works: int p = R.drawable.photo1; image.setImageResource(p); The above will display photo1.jpg but I want to show a random image. I tried the following but it doesn't work. String a = "R.drawable.photo"; int n = (int) (Math.random()*100) String b = Integer.toString(n); String c = a+b; int p = Integer.parseInt(c);//checkpoint image.setImageResource(p); It seems like the string "R.drawable.photoXX" isn't being changed to integer at the checkpoint. Could someone please teach me a right code? Thank you in advance.

• Consuming SAP Web Service from ASP.Net

  - by mehmet6parmak

  Hi, Next week i am supposed to develop an asp.net application which will connect to SAP, retrieve some data, change them and send back to SAP. We decided to use web services to achieve this and now i just want to know what diffuculties may i face with? I have URL of WSDL of the Web Service, will it be enough for me to adding web reference and giving the WSDL's URL? How will i authenticate? And Will it be the same with consuming normal web services? Also i wonder is there anybody that can share a .NET dll that can be used in visual studio 2008? There are some articles relating how to create such a dll using SAP .Net Connector and visual studio 2003 but i could not find anybody sharing the resulting dll under their post. Thanks...

• rails paperclip and passenger `is not recognized by the 'identify' command`

  - by Joseph Silvashy

  When I upload a photo, my model fails validation, err well even without any validations I'm returned this error: /tmp/stream20100103-13830-ywmerx-0 is not recognized by the 'identify' command. and /tmp/stream20100103-13830-ywmerx-0 is not recognized by the 'identify' command. I'm confident this is not related to ImageMagick because I've removed any image processing from the uploading, also I've tried uploading different mime types, like .txt files and the such. Additionally, I found something that may work. A blog post claims that putting the following in my environment (in this case development.rb) Paperclip.options[:command_path] = "/opt/local/bin"

  I've got an imagePickerController which allows the user to take or select an image. In - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; I would like to trigger opening another modal view to capture the caption.

• Visual SourceSafe: Architecture/Management

  - by Nic

  I was looking for information on how other people with larger teams manage SourceSafe currently. I was looking for recommendations and advice for a new project I was setting up that will allow for a few key things Scalability Manage multiple overlapping releases Geared more around .NET however allows for legacy applications (VB, ASP and VBS) I am really looking for any lessons learned from other teams. I come from a StarTeam background and we used view labels and release labels to manage multiple overlapping projects. View labels geared more towards compiled code and SQL and the revision labels were used for VB/ASP projects. Thank you for any advice and sharing your experience and frustrations with other companies you might have worked with in the past.

• PHP, ImageMagick, Google's Page Speed, & JPG File Size Optimization

  - by Sonny

  I have photo gallery code that does image re-sizing and thumbnail creation. I use ImageMagick to do this. I ran a gallery page through Google's Page Speed tool and it revealed that the re-sized images and thumbnails both have about an extra 10KB of data (JPEG files specifically). What can I add to my scripts to optimize the file size? ADDITIONAL INFORMATION I am using the imagick::FILTER_LANCZOS filter with a blur setting of 0.9 when calling the resizeImage() function. JPEGs have a quality setting of 80.

• IE 11 not listening to MSFullscreenChange

  - by Chris

  IE 11 does not seem to be recognizing MSFullscreenChange. I have this code in the script: document.addEventListener("MSFullscreenChange", function () { if (document.msFullscreenElement != null) { console.info("Went full screen"); } else { console.info("Exited full screen"); } }); In other words, I'm using the exact code shown here on Microsoft's own site, but nothing's being printed out in the console, and I know fullscreen is enabled. I also noticed I'm getting the SEC7118 message: XMLHttpRequest for https://gdata.youtube.com/feeds/api/videos/qywzeXowktA?v=2&alt=json required Cross Origin Resource Sharing (CORS). That wouldn't be affecting it, would it?

• Best practices for cross platform git config?

  - by Bas Bossink

  Context A number of my application user configuration files are kept in a git repository for easy sharing across multiple machines and multiple platforms. Amongst these configuration files is .gitconfig which contains the following settings for handling the carriage return linefeed characters [core] autocrlf = true safecrlf = false Problem These settings also gets applied on a GNU/Linux platform which causes obscure errors. Question What are some best practices for handling these platform specific differences in configuration files? Proposed solution I realize this problem could be solved by having a branch for each platform and keeping the common stuff in master and merging with the platform branch when master moves forward. I'm wondering if there are any easier solutions to this problem?

  Hi to all, I keep my Process Documents on SVN and I want to create a Wiki page includes the information about these files. We use SharePoint in the company for basic document sharing and team sites. As it is mentioned in http://stackoverflow.com/questions/256407/what-are-your-biggest-complaints-about-sharepoint SharePoint Wiki lacks of usability. I need an easy to use wiki tool which is capable of showing the content like WikiPedia contents and it would be great if I could have the SharePoint tree view and Active Directory authentication also. I googled it and found Atlassian's Confluence and it seems that this product is capable of the requirements. We use Jira for issue tracking, so we can use it's reporting in dashboards. I need and it has a Wiki part which displays wiki pages in tree view. It should be like Does anyone used Confluence or have an idea for other products which meets my requirements

• Django pagination | get current index of paginated item in page index, (not the page index range its

  - by cka

  I am trying to build a photo gallery with Django. It is set up by category. I have paginated the results of a category by n amount of images per page. I want to also use the paginator on the page that shows just the single image and have a prev/next button for the prev/next image in that category. My thought was to get the current index for the image itself and have that be the link to the /category/CUR_IMG_ID_PAGINATION_LIST/ as the result of paginating the entire set would yield the same index as the current image index in the paginated results. For instance if the image i want is image 45 out of 150 images total for a category, then when i paginate the 150 images the 45 will be the actual number of the page I want. If there's an easier way to do this, let me know. Django 1.1

I want to do something very very similar for a site I'm building. ShareThis offers a widget that does the same thing but it's branded and external. I'm looking for a pure Ruby solution. A gem containing a module that could be included in a Rails ApplicationHelper class would be perfect. Suggestions appreciated before I go reinventing the wheel!

• Jdeveloper vs java/j2ee/js+extjs ?

  - by ssgam

  Hi All, i am new to the web development environment, having came from a unix/c environment. i've been recently asked to create a web app, which i thought would require postgresql, java/j2ee, and javascript for the client interface. as i had wanted a nicer gui, i've been reading up on extjs, which looks really nice to me. a colleague mentioned that the time needed time needed to learn all these various pieces is time consuming, and Jdeveloper seems to provide most of what we'd need (i was shown a demo, which appears to be able to generate some nice web interfaces). what are the pros and cons with the different approaches ? some i can think of: - jdeveloper is an integrated ide, which creates UI easily, tightly integrated with database. (pro) - jdeveloper will be heavier? (con) - wizard generated code may be harder to refactor ? (con) - java/j2ee/js+extjs needs to develop things from ground up (con) thanks in advance for sharing your experiences and thoughts ... sam

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

  new to python here so bear with me ... i'm looking at django for a rapid prototype to a photo sharing app with an amazon aws s3 storage back end. however, as far as i can tell, django is tailored toward the typical database MVC type of pattern. is there a way to for example provide a custom django model implementation that talks to s3 in stead of a DB? a custom DB engine? would either of these be practical, or am i looking in the wrong direction? thanks.

• Any hosted versions of jQuery that have the 'Access-Control-Allow-Origin: *' header set?

  - by Greg Bray

  I have been working with jQuery recently and ran into a problem where I couldn't include it in a userscript because xmlhttpRequest uses the same origin policy. After further testing I found that most browsers also support the Cross-Origin Resource Sharing access control defined by W3C as a workaround for issues with same origin policy. I tested this by hosting the jQuery script on a local web server that included the Access-Control-Allow-Origin: * http header, which allowed the script to be downloaded using xmlhttpRequest so that it could be included in my userscript. I'd like to use a hosted version of jQuery when releasing the script, but so far testing with tools like http://www.seoconsultants.com/tools/headers I have not found any sites that allow cross-origin access to the jQuery script. Here is the list I have tested so far: http://www.asp.net/ajaxlibrary/CDN.ashx http://code.google.com/apis/ajaxlibs/documentation/index.html#jquery http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery Are there any other hosted versions of jQuery that do allow cross origin access?
