• Can I create a custom plist structure definition?

  - by Ed Marty

  When editing plist files in XCode, it can detect the type of plist and show human-readable strings to make it more easy to edit the file. The Info.plist, for example. Thanks to This question, I found the (or a) place where it stores that structure definition, as InfoPlistStructDefs.xcodeplugin. If I put my own file in there, however, nothing interesting happens. That is, it doesn't show up in the list of possible property list types. So does anybody know how to make XCode or the external property list editor application recognize a custom plist structure definition?

• umbraco tiny MCE 3 internet explorer insert link error

  - by user150946

  Hi, I have an instalation of Umbraco 4.0.2.1. In internet explorer (6 / 7) i get an error when trying to insert a link using the tiny MCE rich text editor. basicaly what happens is i can choose the node in the site i want to link to but when i click insert it reloads but the tiny MCE popup does not dissapear and i get the following page error. Line: 368 Char: 9 Error: 'the Form._SCROLLPOSITIONX.value' is null or not an object code: 0 URL: "mydev server"/umbraco/plugins/tinymce3/insertLink.aspx I dont get this problem in Firefox and i have other instalations of umbraco 4.0.2.1 in which this error does not occur. I have tried using WinMerge to comparing the code of the two instalations and they seem identical in all the places i can think would have an effect on tinyMCE ("bin", "umbraco_client\tinymce3", "umbraco\plugins\tinymce3") I am pulling my hair out over this and any help would be very much appreciated.

• Do I need to use any other attributes other than CssClassProperty to enabled design-time support?

  - by keith

  Hi, I'm trying to provide the same design-time support that the CssClass provides on some custom properties of a server control. The documentation suggests that decorating the property with the CssClassProperty is all that's required. [CssClassProperty] public string SomeOtherCssClass{get;set;} This has no effect, in vs2008 or vs2010. I've looked at the WebControl class using reflector and implemented all the attributes, and every combination thereof, to my property and still no class dropdown. Some blog posts suggest that the use of the Editor attribute but a) there's not mention of it in the documentation and b) none of editors which are remotely related to css classes have any effect either. Am I missing something to enable this feature? Thanks in advance, Keith.

• WCF RIA Services build error

  - by soren.enemaerke

  Hi I'm getting a strange error when building my WCF RIA Services Silverlight project in VS2008. In the output I have this message: C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Ria.Client.targets(261,5): error : Failed to write the generated contents of 'C:\projects\[Path_To_Silverlight_Project]\Generated_Code\Analytics.Web.g.cs' to Visual Studio. ...and Visual Studio opens a dialog while building with the following: An editor or project is attempting to save a file that is modified in memory. Saving files during a build is dangerous and may result in incorrect build outputs in the future. Continue with save? The other members on my team seems to be doing just fine, but I can't get past this point (I can if I click 'Continue' which then generate the file just fine but I'm reluclant to do so). There must be some setup or similar that I'm missing here... PS: I'm currently on WinXP and WCF RIA Service beta

• jQuery Plugin for TinyMCE callback

  - by SomewhereThere

  I am using the jQuery plugin from the jQuery build of TinyMCE. This simplified code initializes the editor: $('textarea.tinymce').tinymce({ script_url : '../js/libraries/tiny_mce/tiny_mce.js' }); This loads tiny_mce.js via AJAX. I have code that I want to run once this file is loaded. I essentially want to specify a callback function, but there is no mention of this in the documentation for the plugin. Any ideas? I would be up for adding the functionality if it is not there but I cannot find an uncompressed version of the plugin.

• Help improving a simple assembly function

  - by MPelletier

  I just handed in this function in an assignment. It is done (hence no homework tag). But I would like to see how this can be improved. Essentially, the function sums the squares of all the integers between 1 and the given number, using the following formula: n(n+1)(2n+1)/6 Where n is the maximum number. The function below is made to catch any overflow and return 0 should any occur. UInt32 sumSquares(const UInt32 number) { int result = 0; __asm { mov eax, number //move number in eax mov edx, 2 //move 2 in edx mul edx //multiply (2n) jo end //jump to end if overflow add eax, 1 //addition (2n+1) jo end //jump to end if overflow mov ecx, eax //move (2n+1) in ecx mov ebx, number //move number in ebx add ebx, 1 //addition (n+1) jo end //jump to end if overflow mov eax, number //move number in eax for multiplication mul ebx //multiply n(n+1) jo end //jump to end if overflow mul ecx //multiply n(n+1)(2n+1) jo end //jump to end if overflow mov ebx, 6 //move 6 in ebx div ebx //divide by 6, the result will be in eax mov result, eax //move eax in result end: } return result; } Basically, I want to know what I can improve in there. In terms of best-practices mostly. One thing sounds obvious: smarter overflow check (with a single check for whatever maximum input would cause an overflow).

• Finding most efficient transmission size in varying network latency scenarios

  - by rwmnau

  I'm building a .NET remoting client/server that will be transmitting thousands of files, of varying sizes (everything from a few bytes to hundreds of MB), and I'm curious about a general method for finding the appropriate transmission size. As I see it, there's the following tradeoff: Serialize entire file into a transmission object and transmit at once, regardless of size. This would be the fastest, but a failure during tranmission requires that the whole file be re-transmitted. If the file size is larger than something small (like 4KB), break it into 4KB chunks and transmit those, re-assembling on the server. In addition to the complexity of this, it's slower because of continued round-trips and acknowledgements, though a failure of any one piece doesn't waste much time. The ideal transmission method (when taking into account negotiation latency vs. failure rate) is somewhere in between, and I'm wondering about how to find out the best size for that particular client. Do I have some dynamic tuning step in my transmission that looks at the current bytes/second average, and then raises the transmission size until the speed starts to drop (failures overwhelm negotiation cost)? Or is there some other method for determining ideal transmission size? The application will be multi-threaded, so number of threads also factors in to the calculation. I'm not looking for a formula (though I'll take one if you've got it), but just what to consider as I create this process.

• Rails remove parent HTML tag

  - by gshankar

  It's pretty easy to sanitize HTML and strip ALL instances of a HTML tag using Rails helpers... But how do you just remove ONE tag? In this case, I'm using a WYSIWYG editor that insists on wrapping all my text in a <p> tag. I want to remove this parent tag without stripping out any other <p> tags within the content of the text. I know I could do this in JQuery really easily but I feel like this should be done server-side in my controller before I save the text. Is there a way to do this?

• JMF Registry could not add item (Vista)

  - by Ranch

  Hello, I'm using JMF to capture video stream (webcam) on my Java project. The camera I'm using is recognized by JMF (JFMStudio) and I manage to get the video stream. However, on JMF Registry Editor - there's a list of available capture devices, when I click "Add" on one of the items (including the one I need) I get a "Could not add item" error. Therefore this camera is not set in the registry of it (god know where) and later on it is not recognized by my project: RGBFormat fmt = new RGBFormat(); // could be YUV - doesn't matter Vector v = CaptureDeviceManager.getDeviceList(fmt); v is empty (while I know the video source is recognized by Java , since I manage to get video on JMF Studio). Now, this happens only on Vista (where else) and not on XP. I have a suspiction that somehow Vista security blocks Java from writing the registry file, but of course, I might be wrong. One more comments: this is vfw:Microsoft WDM Image Capture(Win32):0 device. Any idea ?

• Wordpress autoformatting

  - by incrediman

  Why is Wordpress autoformatting my html? It keeps breaking my html code by adding <br>'s and <p>'s everywhere. I mean ffs, it even adds them around html comments. And forget javascript - it adds <div> tags around every line. How can I make it stop? Note: I only want to disable this for a specific page, and the issue is only occuring when editing html using the html content editor within the admin panel.

• Navigating through a sea of hype

  - by wouldLikeACrystalBall

  This is a vague, open question, so if you have no interest in these, please leave now. A few years ago it seemed everyone thought the death of desktop software was imminent. Web applications were the future. Everyone would move to cloud-based software-as-a-service systems, and developing applications for specific end-user platforms like Windows would soon become something of a ghetto. Joel's "How Microsoft Lost the API War" was but one of many such pieces sounding the death knell for this way of software development. Flash-forward to 2010, and the hype is all around mobile devices, particularly the iPhone. Software-as-a-Service vendors--even small ones such as YCombinator startups--go out of their way to build custom applications for the iPhone and other smart phone devices; applications that can be quite sophisticated, that run only on specific hardware and software architectures and are thus inherently incompatible. Now some of you are probably thinking, "Well, only the decline of desktop software was predicted; mobile devices aren't desktops." But the term was used by those predicting its demise to mean laptops also, and really any platform capable of running a browser. What was promised was a world where HTML and related standards would supplant native applications and their inherent difficulties. We would all code to the browser, not the OS. But here we are in 2010 with the AppStore bulging and development for the iPad just revving up. A few days ago, I saw someone on Hacker News claim that the future of computing was entirely in small, portable devices. Apparently the future is underpowered, requires dexterous thumbs and induces near-sightedness. How do those who so vehemently asserted one thing now assert the opposite with equal vehemence, without making even the slightest admission of error? And further, how are we as developers supposed to sift through all of this? I bought into the whole web-standards utopianism that was in vogue back in '06-'07 and now feel like it was a mistake. Is there some formula one can apply rather than a mere appeal to experience?

• Does Sandcastle support Entity Framework Partial Classes?

  - by ChrisHDog

  I am attempting to use Sandcastle (and Sandcastle Help File Builder) to do some "auto-documentation" of some classes I am using. The classes that are giving me trouble are some partial classes on Entity Framework items that add methods and properties to those Framework items. The triple slash comments don't appear to come through on the methods and properties created in the partial classes. I have out how to get xml documentation of the base properties using the short summary and long description fields on the .emdx editor, but that doesn't provide a solution for the items in the partial classes. Is this possible? Is it perhaps just settings that I'm not setting correctly to pick up the partial classes? Does Sandcastle do partial classes in non-Entity Framework settings? Is what I'm doing even possible (has anyone else successfully used the xml created from triple slash comments to create documentation on entity framework partial classes, and if so how did you do that)? Any assistance is appreciated

• Copying Pasting Word 2007 docs to HTML WYSIWYG editors

  - by Graham

  Microsoft word has a ton of proprietary formatting and styles that do not translate well to html WYSIWYG editors. When you paste them over to the html editor and try to edit the pasted info it causes all kinds of clashing styles. I want to be able to keep the general structure but leave out the proprietary stuff. Essentially I want to save clients the headache of having to completely strip out all formatting forcing them to redo all the styling again in the WYSIWYG, but at the same time avoid the conflicts that Word formatting creates. Any ideas?

• Differences between AForge and OpenCV

  - by vrish88

  Hello, I am just learning about computer vision and C#. It seems like two prominent image processing libraries are OpenCV and AForge. What are some of the differences of the two? I am making a basic image editor in C# and while researching I have come across articles on both. But I don't really know why I would choose one over the other. I would like to eventually improve the app to include more advanced functions. Thanks.

• How to get Java Decompiler / JD / JD-Eclipse running in Eclipse Helios

  - by Universalspezialist

  Java Decompiler (JD) is generally recommended as a good, well, Java Decompiler. JD-Eclipse is the Eclipse plugin for JD. I had problems on several different machines to get the plugin running. Whenever I tried to open a .class file, the standard "Source not found" editor would show, displaying lowlevel bytecode disassembly, not the Java source output you'd expect from a decompiler. Installation docs in http://java.decompiler.free.fr/?q=jdeclipse are not bad but quite vague when it comes to troubleshooting. Opening this question to collect additional information: What problems did you encounter before JD was running in Eclipse Helios? What was the solution?

• Undefined variable from import when using wxPython in pydev

  - by Bibendum

  I just downloaded wxPython, and was running some of the sample programs from here. However, on every line that uses a variable from wx.*, I get a "Undefined variable from import error" For example, the following program generates five errors on lines 1,4,8, and two on line 5: import wx class MyFrame(wx.Frame): """ We simply derive a new class of Frame. """ def __init__(self, parent, title): wx.Frame.__init__(self, parent, title=title, size=(200,100)) self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE) self.Show(True) app = wx.App(False) frame = MyFrame(None, 'Small editor') app.MainLoop() The program, however, compiles and runs perfectly. I haven't made any significant modifications to pydev or eclipse, and the wxPython install is fresh.

• Eclipse Outline View - Visible JavaScript Categories in Eclipse?

  - by leeand00

  I just found an option in the little white down arrow in Eclipse that reads "Visible Categories..." How can I use this? It seems to me that it could be used to only show functions that have an @category in their comments, but I haven't been able to make that work. If it did work it would be incredibly useful for separating out Unit Tests from their common-functions and separating them from the setUp and tearDown methods, so what is it really for? By the way I'm editing a Javascript file in the Eclipse "Javascript Editor", I don't know if that makes any difference or not.

• eclipse debugger: attaching source-code of maven managed libraries

  - by meriton

  I'd like to use the source code of maven-managed dependencies when debugging our webapp in eclipse. I have managed to attach the sources to the libraries in the "Maven Managed Depedencies" classpath container, i.e. when I open a class file from a depedency (e.g. using Ctrl-Shift-T), I see the source code. However, when I launch the tomcat within eclipse, and execution halts on a breakpoint in that same class, the editor pane only displays the text "source not found", and a button to edit the "source lookup path". I have attempted to manually add the "Maven Managed Dependencies" classpath container, only to be told "Use maven project settings to configure depedency resolution". However, I see no useful setting in that property pane ... How can I attach those sources?

• jQuery prevent paste to iframe designmode from MS Word

  - by naugtur

  I've seen some questions on catching the paste event. This looks helpful. But I want to prevent paste on a designmode iframe from happening when the pasted content is not plaintext, but comes from MS Word or other WYSIWYG editor. What is experience on that? I suppose I should catch the event (bind to iframe or to its body?) and look for some specific tags in the clipboard. What content does Internet Explorer add every time? [edit] After doing more research I see there is no easy way to work with clipboard in non Internet Explorer browser except some Flash tricks. I don't want them. How can I detect paste in Firefox and others then?

• Excel Prorated SUMIF

  - by Pete Michaud

  I have a worksheet with 2 columns, one is a dollar amount, and the other is a day of the month (1 through 31) that the dollar amount is due by (the dollars are income streams). So, I use the following formula to SUM all the income streams due on or before a certain day: =SUMIF(C5:C14, "<="&$B$42,B5:B14) Column C is the due day B42 is the cell in which I input the day to compare to like "15" for "total of all income due on or before the 15th" - the idea is to have a sum of all income received for the period. Column B is the dollar amount for each income stream. My question is: Some of the income streams don't have a day next to them (the day cell in column C is blank). That means that that income stream doesn't come in as a check or a chunk on a certain date, it trickles in roughly evenly through out the month. So if the amount for the income stream is $10,000 and the day is 15 in a 30 day month, then I should add $5,000 to the total. That would be something like: =SUMIF(C5:C14, "",???) So where the due date is blank, select ???. ??? isn't just the number, it's the number*(given_day/total_days_in_month). So I think what I need for an accurate total is: =SUMIF(C5:C14, "<="&$B$42,B5:B14) + SUMIF(C5:C14, "",???) But I'm not sure how to write that exactly.

• What is all this stuff in the CKEditor folder?

  - by Ashley Ward

  A while ago I downloaded the latest version (3.1) of the CKEditor text editor. The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so : <script type="text/javascript" src="ckeditor/ckeditor.js"></script> this works well. To make config changes, I have been modifying the ckeditor/config.js file. However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages. What is this _source folder? What is all the stuff at the root of the ckeditor folder? and, What is safe to remove from the folder?

• Implementing Naïve Bayes algorithm in Java - Need some guidance

  - by techventure

  hello stackflow people As a School assignment i'm required to implement Naïve Bayes algorithm which i am intending to do in Java. In trying to understand how its done, i've read the book "Data Mining - Practical Machine Learning Tools and Techniques" which has a section on this topic but am still unsure on some primary points that are blocking my progress. Since i'm seeking guidance not solution in here, i'll tell you guys what i thinking in my head, what i think is the correct approach and in return ask for correction/guidance which will very much be appreciated. please note that i am an absolute beginner on Naïve Bayes algorithm, Data mining and in general programming so you might see stupid comments/calculations below: The training data set i'm given has 4 attributes/features that are numeric and normalized(in range[0 1]) using Weka (no missing values)and one nominal class(yes/no) 1) The data coming from a csv file is numeric HENCE * Given the attributes are numeric i use PDF (probability density function) formula. + To calculate the PDF in java i first separate the attributes based on whether they're in class yes or class no and hold them into different array (array class yes and array class no) + Then calculate the mean(sum of the values in row / number of values in that row) and standard divination for each of the 4 attributes (columns) of each class + Now to find PDF of a given value(n) i do (n-mean)^2/(2*SD^2), + Then to find P( yes | E) and P( no | E) i multiply the PDF value of all 4 given attributes and compare which is larger, which indicates the class it belongs to In temrs of Java, i'm using ArrayList of ArrayList and Double to store the attribute values. lastly i'm unsure how to to get new data? Should i ask for input file (like csv) or command prompt and ask for 4 values? I'll stop here for now (do have more questions) but I'm worried this won't get any responses given how long its got. I will really appreciate for those that give their time reading my problems and comment.

• Eclipse or Netbeans for Swing based application?

  - by Nazgulled

  Hi, My next university project is going to be Java based. We will have to develop this with Swing and I was wondering what's the common preference for that? A quick glimpse through Netbeans website and I could see a powerful Swing editor, or what it looks like one; since I never used it, I don't know. As for Eclipse, I'm sure there are plugins for Swing, but are they any good? How do they compare to Netbeans? The bottom line is, should I go with Netbeans or Eclipse for a Swing based project?

• Writing an Iron Python debugger

  - by Kragen

  As a learning exercise I'm writing myself a simple extension / plugin / macro framework using IronPython - I've gotten the basics working but I'd like to add some basic debugging support to make my script editor easier to work with. I've been hunting around on the internet a bit and I've found a couple of good resources on writing managed debuggers (including Mike Stall's excellent .Net Debugging blog and the MSDN documentaiton on the CLR Debugging API) - I understand that IronPython is essentially IL however apart from that I'm a tad lost on how to get started, in particular: Are there any significant differences between debugging a dynamic language (such as IronPython) to a static one (such as C#)? Do I need to execute my script in a special way to get IronPython to output suitable debugging information? Is debugging a script running inside the current process going to cause deadlocks, or does IronPython execute my script in a child process? Am I better off looking into how to produce a simple C# debugger first to get the general idea? (I'm not interested in the GUI aspect of making a debugger for now - I've already got a pretty good idea of how this might work)

• how does vim's autoread work

  Hi, i'm not sure how vim's set autoread works. The help says "When a file has been detected to have been changed outside of Vim and it has not been changed inside of Vim, automatically read it again." So after :set autoread I open a file with vim, I switch to an other editor, change the file, and wait to see the changes in vim as well, nothing happens, I have to say :e to reload the file with the new content. what did i miss? I'm on mac, osx 10.5.8, VIM - Vi IMproved 7.2 thx, best Viktor
