• CGContextSetShadow() - shadow direction reversed between iOS 3.0 and 4.0?

  - by Pascal

  I've been using CGContextSetShadowWithColor() in my Quartz drawing code on the iPhone to generate the "stomped in" look for text and other things (in drawRect: and drawLayer:inContext:). Worked perfectly, but when running the exact same code against iOS 3.2 and now iOS 4.0 I noticed that the shadows are all in the opposite direction. E.g. in the following code I set a black shadow to be 1 pixel above the text, which gave it a "pressed in" look, and now this shadow is 1px below the text, giving it a standard shadow. ... CGContextSetShadowWithColor(context, CGSizeMake(0.f, 1.f), 0.5f, shadowColor); CGContextShowGlyphsAtPoint(context, origin.x, origin.y, glyphs, length); ... Now I don't know whether I am (or have been) doing something wrong or whether there has been a change to the handling of this setting. I haven't applied any transformation that would explain this to me, at least not knowingly. I've flipped the text matrix in one instance, but not in others and this behavior is consistent. Plus I wasn't able to find anything about this in the SDK Release Notes, so it looks like it's probably me. What might be the issue?

• What's the recommended implemenation for hashing OLE Variants?

  - by Barry Kelly

  OLE Variants, as used by older versions of Visual Basic and pervasively in COM Automation, can store lots of different types: basic types like integers and floats, more complicated types like strings and arrays, and all the way up to IDispatch implementations and pointers in the form of ByRef variants. Variants are also weakly typed: they convert the value to another type without warning depending on which operator you apply and what the current types are of the values passed to the operator. For example, comparing two variants, one containing the integer 1 and another containing the string "1", for equality will return True. So assuming that I'm working with variants at the underlying data level (e.g. VARIANT in C++ or TVarData in Delphi - i.e. the big union of different possible values), how should I hash variants consistently so that they obey the right rules? Rules: Variants that hash unequally should compare as unequal, both in sorting and direct equality Variants that compare as equal for both sorting and direct equality should hash as equal It's OK if I have to use different sorting and direct comparison rules in order to make the hashing fit. The way I'm currently working is I'm normalizing the variants to strings (if they fit), and treating them as strings, otherwise I'm working with the variant data as if it was an opaque blob, and hashing and comparing its raw bytes. That has some limitations, of course: numbers 1..10 sort as [1, 10, 2, ... 9] etc. This is mildly annoying, but it is consistent and it is very little work. However, I do wonder if there is an accepted practice for this problem.

• Smoothing touch-based animation in iPhone OpenGL?

  - by quixoto

  I know this is vague, but looking for general tips/help on this, as it's not an area of significant expertise for me. I have some iPhone code that's basically an EAGL view handling a single touch. The app draws (using GL) a circle via triangle fan at the touch point, and moves it when the user moves the touch point, and re-renders the view then. When dragging a finger slowly, the circle keeps up and consistent with the finger as it moves. If I scribble my finger quickly back and forth across the screen, the rendering doesn't keep up with the touch motion, so you see an optical illusion of "multiple" discrete circles on the screen "at once". (Normal persistence of vision illusion). This optical illusion is jarring. How can I make this look more natural? Can I blur the motion of the circle somehow? Is this result the evidence of some bad frame rate issue? I see this artifact even when nothing else is being rendered, so I think this might just be as fast as we can go. Any hints or suggestions? Much appreciated. Thanks.

• COM Object Clean Up

  - by Reggie McCray

  What is the difference between the two lines of code below: CComPtr< IInterface > m_interface; IInterface* m_interface; I know that CComPtr help eliminate memory leaks, but I am getting inconsistent results. When declaring the pointer with CComPtr< IInterface > m_interface; and using the interface in my C# code there are no errors, however using the Interface in VC++ I get an unhandled exception error, even if I comment out the instance creation of IInterface. I am pretty sure the problem is in here somewhere: STDMETHODIMP CSomeClass::get_IClass(IClass** var) { return m_class_var->QueryInterface(var); } STDMETHODIMP CSomeClass::putref_IClass(IClass* var) { m_class_var = var; return S_OK; } When I declare the interface pointer with: IInterface* m_interface; I get a RPC_E_SERVERFAULT error when testing the Interface in C# and have to explicitly call GC.Collect() to avoid the error being thrown after instantiation of a few objects. When testing the Interface in VC++ the error is consistent however when it occurs is different. If I comment out the instance creation of IInterface the code runs fine, however when I try to create an instance I get same error as before, just a vague unhandled exception error. What am I doing wrong here?

• Determine whether .NET assemblies were built from the same source

  - by Clayton

  Does anyone know of a way to compare two .NET assemblies to determine whether they were built from the "same" source files? I am aware that there are some differencing utilities available, such as the plugin for Reflector, but I am not interested in viewing differences in a GUI, I just want an automated way to compare a collection of binaries to see whether they were built from the same (or equivalent) source files. I understand that multiple different source files could produce the same IL, and realise that the process would only be sensitive to differences in the IL, not the original source. The main obstacle to just comparing the byte streams for the two assemblies is that .NET includes a field called "MVID" (Module Version Identifier) the assembly. This appears to have a different value for every compilation, so if you build the same code twice the assembly will be different. A related question is, does anyone know how to force the MVID to be the same for each compilation? This would avoid us needing to have a comparison process that is insensitive to differences in the value of the MVID. A consistent MVID would be preferable, as this means that standard checksums could be used. The background behind this is that a third-party company is responsible for independently reviewing and signing off our releases, prior to us being permitted to release to Production. This includes reviewing the source code. They want to independently confirm that the source code we give them matches the binaries that we earlier built, tested and currently plan to deploy. We are looking for a process that allows them to independently build the system from the source we supply them with, and the compare the checksums against the checksums for the binaries we have tested. thanks

• How to use javascript-xpath

  - by Nirmal Patel

  I am using Selenium RC with IE 6 and XPath locators are terribly slow. So I am trying to see if javascript-xpath actually speeds up things. But could not find enough/clear documentation on how to use native x- path libraries. I am doing the following: protected void startSelenium (String testServer, String appName, String testInBrowser){ selenium = new DefaultSelenium("localhost", 4444, "*" +testInBrowser, testServer+ "/"+ appName + "/"); echo("selenium instance created:"+selenium.getClass()); selenium.start(); echo("selenium instance started..." + testServer + "/" + appName +"/"); selenium.runScript("lib/javascript-xpath-latest-cmp.js"); selenium.useXpathLibrary("javascript-xpath"); selenium.allowNativeXpath("true"); } This results in speed improvement of XPath locator but the improvements are not consistent. On some runs the time taken for a locator is halved; while sometimes its randomly high. Am I missing any configuration step here? Would be great if someone who has had success with this could share their views and approach. Thanks, Nirmal

• file layout and setuptools configuration for the python bit of a multi-language library

  - by dan mackinlay

  So we're writing a full-text search framework MongoDb. MongoDB is pretty much javascript-native, so we wrote the javascript library first, and it works. Now I'm trying to write a python framework for it, which will be partially in python, but partially use those same stored javascript functions - the javascript functions are an intrinsic part of the library. On the other hand, the javascript framework does not depend on python. since they are pretty intertwined it seems like it's worthwhile keeping them in the same repository. I'm trying to work out a way of structuring the whole project to give the javascript and python frameworks equal status (maybe a ruby driver or whatever in the future?), but still allow the python library to install nicely. Currently it looks like this: (simplified a little) javascript/jstest/test1.js javascript/mongo-fulltext/search.js javascript/mongo-fulltext/util.js python/docs/indext.rst python/tests/search_test.py python/tests/__init__.py python/mongofulltextsearch/__init__.py python/mongofulltextsearch/mongo_search.py python/mongofulltextsearch/util.py python/setup.py I've skipped out a few files for simplicity, but you get the general idea; it' a pretty much standard python project... except that it depends critcally ona whole bunch of javascript which is stored in a sibling directory tree. What's the preferred setup for dealing with this kind of thing when it comes to setuptools? I can work out how to use package_data etc to install data files that live inside my python project as per the setuptools docs. The problem is if i want to use setuptools to install stuff, including the javascript files from outside the python code tree, and then also access them in a consistent way when I'm developing the python code and when it is easy_installed to someone's site. Is that supported behaviour for setuptools? Should i be using paver or distutils2 or Distribute or something? (basic distutils is not an option; the whole reason I'm doing this is to enable requirements tracking) How should i be reading the contents of those files into python scripts?

• How do I remove accents from characters in a PHP string?

  - by georgebrock

  I'm attempting to remove accents from characters in PHP string as the first step to making the string usable in a URL. I'm using the following code: $input = "Fóø Bår"; setlocale(LC_ALL, "en_US.utf8"); $output = iconv("utf-8", "ascii//TRANSLIT", $input); print($output); The output I would expect would be something like this: F'oo Bar However, instead of the accented characters being transliterated they are replaced with question marks: F?? B?r Everything I can find online indicates that setting the locale will fix this problem, however I'm already doing this. I've already checked the following details: The locale I am setting is supported by the server (included in the list produced by locale -a) The source and target encodings (UTF-8 and ASCII) are supported by the server's version of iconv (included in the list produced by iconv -l) The input string is UTF-8 encoded (verified using PHP's mb_check_encoding function, as suggested in the answer by mercator) The call to setlocale is successful (it returns 'en_US.utf8' rather than FALSE) The cause of the problem: The server is using the wrong implementation of iconv. It has the glibc version instead of the required libiconv version. Note that the iconv function on some systems may not work as you expect. In such case, it'd be a good idea to install the GNU libiconv library. It will most likely end up with more consistent results. – PHP manual's introduction to iconv Details about the iconv implementation that is used by PHP are included in the output of the phpinfo function. (I'm not able to re-compile PHP with the correct iconv library on the server I'm working with for this project so the answer I've accepted below is the one that was most useful for removing accents without iconv support.)

• How to Encourage More Frequent Commits to SVN

  - by Yaakov Ellis

  A group of developers that I am working with switched from VSS to SVN about half a year ago. The transition from CheckOut-CheckIn to Update-Commit has been hard on a number of users. Now that they are no longer forced to check in their files when they are done (or more accurately, now that no one else can see that they have the file checked out and tell them to check back in in order to release the lock on the file), it has happened on more than one occasion that users have forgotten to Commit their changes until long after they were completed. Although most users are good about Committing their changes, the issue is serious enough that the decision might be made to force users to get locks on all files in SVN before editing. I would rather not see this happen, but I am at a loss over how to improve the situation in another way. So can anyone suggest ways to do any of the following: Track what files users have edited but have not yet Committed changes for Encourage users to be more consistent with Committing changes when they are done Help finish off the user education necessary to get people used to the new version control paradigm Out-of-the-box solutions welcome (ie: desktop program that reminds users to commit if they have not done so in a given interval, automatically get stats of user Commit rates and send warning emails if frequency drops below a certain threshold, etc).

• Delegates in .NET: how are they constructed ?

  - by Saulius

  While inspecting delegates in C# and .NET in general, I noticed some interesting facts: Creating a delegate in C# creates a class derived from MulticastDelegate with a constructor: .method public hidebysig specialname rtspecialname instance void .ctor(object 'object', native int 'method') runtime managed { } Meaning that it expects the instance and a pointer to the method. Yet the syntax of constructing a delegate in C# suggests that it has a constructor new MyDelegate(int () target) where I can recognise int () as a function instance (int *target() would be a function pointer in C++). So obviously the C# compiler picks out the correct method from the method group defined by the function name and constructs the delegate. So the first question would be, where does the C# compiler (or Visual Studio, to be precise) pick this constructor signature from ? I did not notice any special attributes or something that would make a distinction. Is this some sort of compiler/visualstudio magic ? If not, is the T (args) target construction valid in C# ? I did not manage to get anything with it to compile, e.g.: int () target = MyMethod; is invalid, so is doing anything with MyMetod, e.g. calling .ToString() on it (well this does make some sense, since that is technically a method group, but I imagine it should be possible to explicitly pick out a method by casting, e.g. (int())MyFunction. So is all of this purely compiler magic ? Looking at the construction through reflector reveals yet another syntax: Func CS$1$0000 = new Func(null, (IntPtr) Foo); This is consistent with the disassembled constructor signature, yet this does not compile! One final interesting note is that the classes Delegate and MulticastDelegate have yet another sets of constructors: .method family hidebysig specialname rtspecialname instance void .ctor(class System.Type target, string 'method') cil managed Where does the transition from an instance and method pointer to a type and a string method name occur ? Can this be explained by the runtime managed keywords in the custom delegate constructor signature, i.e. does the runtime do it's job here ?

• SoundManager2 has irregular latency

  - by Stefan Monov

  I'm playing some notes at regular intervals. Each one is delayed by a random number of milliseconds, creating a jarring irregular effect. How do I fix it? Note: I'm OK with some latency, just as long as it's consistent. Answers of the type "implement your own small SoundManager2 replacement, optimized for timing-sensitive playback" are OK, if you know how to do that :) but I'm trying to avoid rewriting my whole app in flash for now. For an example of app with zero audible latency see the flash-based ToneMatrix. Testcase (see it here live or get it in an zip): <head> <title></title> <script type="text/javascript" src="http://www.schillmania.com/projects/soundmanager2/script/soundmanager2.js"> </script> <script type="text/javascript"> soundManager.url = '.' soundManager.flashVersion = 9 soundManager.useHighPerformance = true soundManager.useFastPolling = true soundManager.autoLoad = true function recur(func, delay) { window.setTimeout(function() { recur(func, delay); func(); }, delay) } soundManager.onload = function() { var sound = soundManager.createSound("test", "test.mp3") recur(function() { sound.play() }, 300) } </script> </head> <body> </body> </html>

• Allowed unicode characters in IDN host labels

  - by Roland Franssen

  Hi all, Im currently working on a "proper" URI validator and currently it all comes down to hostname validation, the rest isnt that tricky. Im stuck at IDN hostname labels (e.g. containing unicode; possible punycode encoded strings have been decoded at this point). My first idea was basicly a regex for TLD's not supporting IDN and one for those who do (http://www.mozilla.org/projects/security/tld-idn-policy-list.html (?)). Respectively; ^[a-zA-Z0-9-]+$ and ^[a-zA-Z0-9-\p{L}]+$ However this is not an ideal situation, since every IDN registrar can decide which characters to allow and which not. What im looking for is a proper, consistent, up2date data table of unicode characters allowed in various TLD's; im getting this idea i have to find all the data myself at russian and chinese registry sites (which is quite difficult). So before spitting down the web.. i wondered is there such a list? Or are there better approaches, best/common practices etc? (I want the validation to be as strict as possible.) Any help is welcome! // Roland

• Evaluation of environment variables in command run by Java's Runtime.exec()

  - by Tom Duckering

  Hi, I have a scenarios where I have a Java "agent" that runs on a couple of platforms (specifically Windows, Solaris & AIX). I'd like to factor out the differences in filesystem structure by using environment variables in the command line I execute. As far as I can tell there is no way to get the Runtime.exec() method to resolve/evaluate any environment variables referenced in the command String (or array of Strings). I know that if push comes to shove I can write some code to pre-process the command String(s) and resolve enviroment variables by hand (using getEnv() etc). However I'm wondering if there is a smarter way to do this since I'm sure I'm not the only person wanting to do this and I'm sure there are pitfalls in "knocking up" my own implementation. Your guidance and suggestions are most welcome. edit: I would like to refer to environment variables in the command string using some consistent notation such as $VAR and/or %VAR%. Not fussed which. edit: To be clear I'd like to be able to execute a command such as: perl $SCRIPT_ROOT/somePerlScript.pl args on Windows and Unix hosts using Runtime.exec(). I specify the command in config file that describes a list of jobs to run and it has to be able to work cross platform, hence my thought that an environment variable would be useful to factor out the filesystem differences (/home/username/scripts vs C:\foo\scripts). Hope that helps clarify it. Thanks. Tom

• Python - CSV: Large file with rows of different lengths

  In short, I have a 20,000,000 line csv file that has different row lengths. This is due to archaic data loggers and proprietary formats. We get the end result as a csv file in the following format.

• Project ideas for automated deduction/automated theorem proving?

  - by wsh

  Dear Stack Overflow brethren, I'm a second-semester junior who will embark upon my thesis soon, and I have an interest in automated deduction and automated theorem provers. As in, I'd like to advance the art in some way (I don't mean that pretentiously, but I do want to do something productive). I've Googled pretty far and wide and so far few promising ideas have emerged. There are a few student project idea pages, but most seem either horribly outdated or too advanced (I was originally going to attempt to synthesize postmodernist thought (hahaha) and abstract its logical content, build a complete and consistent model (if possible, of course), and attempt to automate it, grounding said model as possible in a nonstandard logic a la these. My advisor thought that gave postmodernist thought too much credit (a while ago I reimplemented the Postmodernism Generator in Haskell with Parsec, so that is in part where the idea came from); I am tempted to concur.) So, yeah. Does anyone have ideas? I apologize if there is some obvious gap in my approach here/if I haven't appropriately done my homework (and if there is one, please tell me!), but in large part I don't even know where to start, and thank you for reading all that.

• Date since 1600 to NSDate?

  - by Steven Fisher

  I have a date that's stored as a number of days since January 1, 1600 that I need to deal with. This is a legacy date format that I need to read many, many times in my application. Previously, I'd been creating a calendar, empty date components and root date like this: self.gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar ] autorelease]; id rootComponents = [[[NSDateComponents alloc] init] autorelease]; [rootComponents setYear: 1600]; [rootComponents setMonth: 1]; [rootComponents setDay: 1]; self.rootDate = [gregorian dateFromComponents: rootComponents]; self.offset = [[[NSDateComponents alloc] init] autorelease]; Then, to convert the integer later to a date, I use this: [offset setDay: theLegacyDate]; id eventDate = [gregorian dateByAddingComponents: offset toDate: rootDate options: 0]; (I never change any values in offset anywhere else.) The problem is I'm getting a different time for rootDate on iOS vs. Mac OS X. On Mac OS X, I'm getting midnight. On iOS, I'm getting 8:12:28. (So far, it seems to be consistent about this.) When I add my number of days later, the weird time stays. OS | legacyDate | rootDate | eventDate ======== | ========== | ==========================|========================== Mac OS X | 143671 | 1600-01-01 00:00:00 -0800 | 1993-05-11 00:00:00 -0700 iOS | 143671 | 1600-01-01 08:12:28 +0000 | 1993-05-11 07:12:28 +0000 In the previous release of my product, I didn't care about the time; now I do. Why the weird time on iOS, and what should I do about it? (I'm assuming the hour difference is DST.) I've tried setting the hour, minute and second of rootComponents to 0. This has no impact. If I set them to something other than 0, it adds them to 8:12:28. I've been wondering if this has something to do with leap seconds or other cumulative clock changes. Or is this entirely the wrong approach to use on iOS?

• Best Practices for Setup and Management of an Open Source Project

  - by VirtuosiMedia

  Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

• WinForms Load Event / Static Initialization Strangeness

  - by Eric J.

  Background I'm troubleshooting an WinForms 2.0 program that's already been burned to CD for distribution to an internet-challenged target audience. Some users are experiencing a fatal error that I can reproduce locally. Reproducing the Error I get the fatal error when I log into my Vista box using a standard user that I just created, even if I run the program as administrator. I do not get the fatal error when I log in as local administrator. I'm not sure that being administrator is necessarily the trigger (since runas did not help). I have reproduced this half a dozen times under each account with consistent results. The faulty code Base.cs (base class for several user controls, only one of which is shown on first screen) private void BaseWindow_Load(object sender, EventArgs e) { // This message shown once in both cases MessageBox.Show("BaseWindow_Load for " + this.GetType().FullName); SkinManager.ApplySkin(this); } SkinManager.cs private static Skin skin = null; public static void ApplySkin(UserControl applyTo) { if (skin == null) { skin = new Skin(SkinsDirectory, "Default"); } } Skin.cs internal Skin(string skinPath, string skinName) { config = SkinConfig.Load(path); } SkinConfig.cs public static SkinConfig Load(string path) { // This message shown only once running as Admin but twice running as standard user System.Windows.Forms.MessageBox.Show("@1"); // !!! LOCK path HERE !!! } A user control loads on the first form, which triggers a call to SkinManager.ApplySkin, which checks if skin is null and, if so assigns it (without thread synchronization or recursion protection), which ultimately causes a file to be opened. When logged in as local admin, that sequence completes just fine. When logged in as my test standard user, ApplySkin is always called a second time while skin is still null, causing a second attempt to load, causing the file to be locked on the second attempt. The error handling is draconian at this point and the program terminates. The Question While this code can be easily fixed, I would like to understand why the error is happening only in some cases.

• Encoding issue - 2nd band of ISO-8859-1 values do not get encoded?

  - by bstack

  Hello, I want to send the pound sign character i.e. '£' encoded as ISO-8859-1 across the wire. I perform this by doing the following: var _encoding = Encoding.GetEncoding("iso-8859-1"); var _requestContent = _encoding.GetBytes(requestContent); var _request = (HttpWebRequest)WebRequest.Create(target); _request.Headers[HttpRequestHeader.ContentEncoding] = _encoding.WebName; _request.Method = "POST"; _request.ContentType = "application/x-www-form-urlencoded; charset=iso-8859-1"; _request.ContentLength = _requestContent.Length; _requestStream = _request.GetRequestStream(); _requestStream.Write(_requestContent, 0, _requestContent.Length); _requestStream.Flush(); _requestStream.Close(); When I put a breakpoint at the target, I expect to receive the following: '%a3', however I receive '%u00a3' instead. ISO-8859-1 is divided into 2 groups of characters: (ref: http://en.wikipedia.org/wiki/ISO_8859-1) The lower range 20 to 7E - is where all characters seem to be encoded correctly The higher range A0 to FF - is where all characters seem to encode to their Unicode equivalent value As '£' is in higher range A0 to FF, it gets encoded to %u00a3. In fact when I use the first few characters of the higher range A0 to FF i.e. '¡¢£¤¥¦§¨©ª«¬®', I get '%u00a1%u00a2%u00a3%u00a4%u00a5%u00a6%u00a7%u00a8%u00a9%u00aa%u00ab%u00ac%u00ae'. This behaviour is consistent. The question I have is why do characters in the higher range A0 to FF get encoded to their unicode value - and not to their equivalent ISO-8859-1 value? Help would be greatly appreciated... Billy

• What is the fastest way to pull a few element values out of XML files in Perl?

  - by Anon Guy

  I have a bunch of XML files that are about 1-2 megabytes in size. Actually, more than a bunch, there are millions. They're all well-formed and many are even validated against their schema (confirmed with libxml2). All were created by the same app, so they're in a consistent format (though this could theoretically change in the future). I want to check the values of one element in each file from within a Perl script. Speed is important (I'd like to take less than a second per file) and as noted I already know the files are well-formed. I am sorely tempted to simply 'open' the files in Perl and scan through until I see the element I am looking for, grab the value (which is near the start of the file), and close the file. On the other hand, I could use an XML parser (which might protect me from future changes to the XML formatting) but I suspect it will be slower than I'd like. Can anyone recommend an appropriate approach and/or parser? Thanks in advance.

• Why is WMDC/ActiveSync so flaky?

  - by Ira Rainey

  I'm developing a Windows Mobile app using the .NET Compact Framework 3.5 and VS2008, and for debugging using the Device Emulator V3, on Win7, and seem to have constant problems with Windows Mobile Device Centre (6.1) connecting. Using the Emulator Manager (9.0.21022.8) I cradle the device using DMA in WMDC. The problem is it's so flaky at actually connecting that it's becoming a pain. I find that when I turn my computer on, before I can get it to connect I have to open up WMDC, disable Connect over DMA, close WMDC down, reopen it again, and then it might cradle. Often I have to do this twice before it will cradle. Once it's cradled it's generally fine, but nothing seems consistent in getting it to connect. Connecting with physical devices is often better, although not always. If I plug a PDA into a USB socket other than the one it was originally plugged into then it won't connect at all. Often the best/most reliable connection method seems to be over Bluetooth, but that's quite slow. Anybody got any tips or advice?

• Test Results window in VS2008 not showing results

  - by TimK

  I have an existing solution that has been working for a long time, containing around 600 tests in a couple of test projects. I recently moved to a new PC - it's Win7-x64, and I installed a fresh copy of VS2008. When I first opened the solution on the new machine, the Test List Editor was completely empty. Trying to create a new test list caused the editor to refresh, and now it shows my test lists, but they're acting funny. I can select tests in the lists, and run them, but the results window doesn't usually update automatically to show the results of the latest test. It has done this when running a single test a couple of times, but even that is not consistent. The only way I can view the results is by manually going to the Test Runs window and connecting to individual test runs. When I do that, the results show up in the results list, but I can't check them to re-run the failed tests - the check boxes are all disabled. I guess I should describe the way it used to work, in case that was unusual - I used to select some tests from the Test Lists window, tell it to run them, and the results window would clear itself, and then display the results from the current run. I could then check any tests that I wanted to re-run, and use the run/debug button in the results window to do so. Any ideas what's going on here?

• How to Create Deterministic Guids

  - by desigeek

  In our application we are creating Xml files with an attribute that has a Guid value. This value needed to be consistent between file upgrades. So even if everything else in the file changes, the guid value for the attribute should remain the same. One obvious solution was to create a static dictionary with the filename and the Guids to be used for them. Then whenever we generate the file, we look up the dictionary for the filename and use the corresponding guid. But this is not feasible coz we might scale to 100's of files and didnt want to maintain big list of guids. So another approach was to make the Guid the same based on the path of the file. Since our file paths and application directory structure are unique, the Guid should be unique for that path. So each time we run an upgrade, the file gets the same guid based on its path. I found one cool way to generate such 'Deterministic Guids' (Thanks Elton Stoneman). It basically does this: private Guid GetDeterministicGuid(string input) { //use MD5 hash to get a 16-byte hash of the string: MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider(); byte[] inputBytes = Encoding.Default.GetBytes(input); byte[] hashBytes = provider.ComputeHash(inputBytes); //generate a guid from the hash: Guid hashGuid = new Guid(hashBytes); return hashGuid; } So given a string, the Guid will always be the same. Are there any other approaches or recommended ways to doing this? What are the pros or cons of that method?

• How to create a variadic (with variable length argument list) function wrapper in JavaScript

  - by U-D13

  The intention is to build a wrapper to provide a consistent method of calling native functions with variable arity on various script hosts - so that the script could be executed in a browser as well as in the Windows Script Host or other script engines. I am aware of 3 methods of which each one has its own drawbacks. eval() method: function wrapper () { var str = ''; for (var i=0; i<arguments.lenght; i++) str += (str ?', ':'') + ',arguments['+i+']'; return eval('[native_function] ('+str+')'); } switch() method: function wrapper () { switch (arguments.lenght) { case 0: return [native_function] (arguments[0]); break; case 1: return [native_function] (arguments[0], arguments[1]); break; ... case n: return [native_function] (arguments[0], arguments[1], ... arguments[n]); } } apply() method: function wrapper () { return [native_function].apply([native_function_namespace], arguments); } What's wrong with them you ask? Well, shall we delve into all the reasons why eval() is evil? And also all the string concatenation... Not a solution to be labeled "elegant". One can never know the maximum n and thus how many cases to prepare. This also would strech the script to immense proportions and sin against the holy DRY principle. The script could get executed on older (pre- JavaScript 1.3 / ECMA-262-3) engines that don't support the apply() method. Now the question part: is there any another solution out there?

• Read-only view of a Java list with more general type parameter

  - by Michael Rusch

  Suppose I have class Foo extends Superclass. I understand why I can't do this: List<Foo> fooList = getFooList(); List<Superclass> supList = fooList; But, it would seem reasonable for me to do that if supList were somehow "read-only". Then, everything would be consistent as everything that would come out of an objList would be a Foo, which is a Superclass. I could probably write a List implementation that would take an underlying list and a more general type parameter, and would then return everything as the more general type instead of the specific type. It would work like the return of Collections.unmodifiableList() except that the type would be made more general. Is there an easier way? The reason I'm considering doing this is that I am implementing an interface that requires that I return an (unmodifiable) List<Superclass>, but internally I need to use Foos, so I have a List<Foo>. I can't just cast.
