  • Using Crypt function Python 3.3.2

    - by adampski
    In Windows and Python version 3.3.2, I try and call the python module like so: hash2 = crypt(word, salt) I import it at the top of my program like so: from crypt import * The result I get is the following: Traceback (most recent call last): File "C:\none\of\your\business\adams.py", line 10, in <module> from crypt import * File "C:\Python33\lib\crypt.py", line 3, in <module> import _crypt ImportError: No module named '_crypt' However, when I execute the same file adams.py in Ubuntu, with Python 2.7.3, it executes perfectly - no errors. I tried the following to resolve the issue for my Windows & Python 3.3.2 (though I'm sure the OS isn't the issue, the Python version or my use of syntax is the issue): Rename the directory in the Python33 directory from Lib to lib Rename the crypt.py in lib to _crypt.py. However, it turns out the entire crypt.py module depends on an external module called _crypt.py too. Browsed internet to download anything remotely appropriate to resemble _crypt.py It's not Python, right? It's me...(?) I'm using syntaxes to import and use external modules that are acceptable in 2.7.3, but not in 3.3.2. Or have I found a bug in 3.3.2?

  • 407 Proxy Authentication Required

    - by Hemant Kothiyal
    I am working on a website, in which I am retrieving XML data from an external URL, using the following code WebRequest req = WebRequest.Create("External server url"); req.Proxy = new System.Net.WebProxy("proxyUrl:8080", true); req.Proxy.Credentials = CredentialCache.DefaultCredentials; WebResponse resp = req.GetResponse(); StreamReader textReader = new StreamReader(resp.GetResponseStream()); XmlTextReader xmlReader = new XmlTextReader(textReader); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlReader); This code is working fine on my development PC (Windows XP with .Net 3.5) But when I deploy this code to IIS (Both at Windows XP and at Windows Server 2003) it's giving me following error "The remote server returned an error: (407) Proxy Authentication Required." Sometimes it gives me "The remote server returned an error: (502) Bad Gateway." Following code is from my web.config <system.net> <defaultProxy> <proxy usesystemdefault="False" proxyaddress ="http://172.16.12.12:8080" bypassonlocal ="True" /> </defaultProxy> </system.net> Please help me ? [Edit] Even when i run the website for devlopment PC but through IIS it gives me error "The remote server returned an error: (407) Proxy Authentication Required." But when i run website from Microsoft Devlopment server, it is running fine

  • How to do proper Unicode and ANSI output redirection on cmd.exe?

    - by Sorin Sbarnea
    If you are doing automation on windows and you are redirecting the output of different commands (internal cmd.exe or external, you'll discover that your log files contains combined Unicode and ANSI output (meaning that they are invalid and will not load well in viewers/editors). Is it is possible to make cmd.exe work with UTF-8? This question is not about display, s about stdin/stdout/stderr redirection and Unicode. I am looking for a solution that would allow you to: redirect the output of the internal commands to a file using UTF-8 redirect output of external commands supporting Unicode to the files but encoded as UTF-8. If it is impossible to obtain this kind of consistence using batch files, is there another way of solving this problem, like using python scripting for this? In this case, I would like to know if it is possible to do the Unicode detection alone (user using the scripting should not remember if the called tools will output Unicode or not, it will just expect to convert the output to UTF-8. For simplicity we'll assume that if the tool output is not-Unicode it will be considered as UTF-8 (no codepage conversion).

  • SIGABRT error when running on iPad

    - by user324881
    Hello, all. I've been banging my head for a few hours because of this problem. I have a universal project that's a mix of iPhone and iPad projects. I put these codebases together into the universal project and, after a lot of "#if __IPHONE_OS_VERSION_MIN_REQUIRED >= 30200" checks, got the project to run in both the iPhone (OS 3.0 to 3.1.3) and iPad simulators. After doing a more finagling with the project settings of external libraries that I load, I got the app to load on an iPhone (which runs OS 3.1.3). However, when I run the app on my iPad, I get an immediate SIGABRT error. I've tried running it under Debug, under Release, with Active Architecture of both armv6 and armv7. I've checked and double-checked that the app has the right nib files set up (but, again, this app runs fine in the simulator). I've gone through the external libraries I'm using and set them up to have the same base SDK (3.2), same architectures (Optimized (armv6 armv7)), the same targeted device family (iPhone/iPad), and the same iPhone OS deployment target (iPhone OS 3.0). So, to summarize... I have a universal app that works in the simulator for iPhone and iPad, runs on an actual iPhone, but doesn't run on an iPad. It doesn't get far on the iPad -- there's an immediate SIGABRT error that stops execution. Help??

  • Need content in UIWebView to display quickly

    - by leftspin
    Part of my app caches web pages for offline viewing. To do that, I am saving the HTML fetched from a site and rewriting img urls to point to a file on the local store. When I load the html into a UIWebView, it loads the images as expected and everything's fine. I am also caching stylesheets in this fashion. The problem is that when I put the phone into airplane mode, loading this cached html causes the UIWebView to display a blank screen and pause for a while before displaying the page. I've figured out that it's caused by non-cached URLs referenced from the original HTML doc that the web view is trying to fetch. These other URLs include images within the cached stylesheets, content in iframes, and javascript that opens a connection to fetch other resources. The pause happens when the UIWebView tries to fetch these resources, and the web page only appears after all these other fetches have timed out. My questions is, how can I make UIWebView just display the stuff I've cached immediately? Here are my thoughts: write even more code to cache these other references. This is potentially a ton more code to catch all the edge cases, etc., especially having to parse the Javascript to see what it loads after the page is loaded force UIWebView to time out immediately so there's no pause. I haven't figured out how to do this. somehow get what's already loaded to display even though the external references haven't finished fetching yet strip the code of all scripts, link tags and iframes to "erase" the external references. I've tried this one, but for some sites, the resultant page is severely messed up Can anyone help me here? I've been working on this forever, and am running out of ideas.

  • Unable to debug XBAP with Visual Studio 2010

    - by Oleg I.
    Just migrated my project to Visual Studio 2010, but target framework was left 3.5. Project contains an XBAP app in partial trust and a bunch of WCF services. Debugging is configured to start PresentationHost.exe with -debug and -debugSecurityZoneUrl parameters. Under VS2008 everything works fine, and in VS2010 Beta2 (don't sure about RC), but under VS2010 RTM debugging is for some reason doesn't working. Application runs, but doesn't hit any breakpoint. And if for example exception occurs, message box appears "Do you wish to debug or close..." and after I choose "debug" option new weird message box appears: --------------------------- Warning --------------------------- A debugger is attached to PresentationHost.exe but not configured to debug this unhandled exception. To debug this exception, detach the current debugger. An unhandled exception was raised from Microsoft .NET Framework v 1.0, 1.1, or 2.0, but the current debugger is configured to debug Microsoft .NET Framework v4.0 code. Examine the exception using the SOS tool. --------------------------- OK --------------------------- And where is the vaunted multitargeting? Did anyone have already bumped into same issue? UPDATE: Tried to debug with "Start browser with URL" option. Debugging is working, but I get SecurityException. So it is possible, just need to figure out how to make it work with "Start external program" option. UPDATE2: Checked what PresentationHost is actually loads in both scenarios: "Start external program" - Latest version (4.0.31106.0) from C:\Windows\System32\ "Start browser with URL" - Old version (3.0.6920.4902) from C:\Windows\winsxs\x86_wpf-presentationhostexe_31bf3856ad364e35_6.1.7600.16385_none_6fca8974817173aa

  • A couple of questions on exceptions/flow control and the application of custom exceptions

    - by dotnetdev
    1) Custom exceptions can help make your intentions clear. How can this be? The intention is to handle or log the exception, regardless of whether the type is built-in or custom. The main reason I use custom exceptions is to not use one exception type to cover the same problem in different contexts (eg parameter is null in system code which may be effect by an external factor and an empty shopping basket). However, the partition between system and business-domain code and using different exception types seems very obvious and not making the most of custom exceptions. Related to this, if custom exceptions cover the business exceptions, I could also get all the places which are sources for exceptions at the business domain level using "Find all references". Is it worth adding exceptions if you check the arguments in a method for being null, use them a few times, and then add the catch? Is it a realistic risk that an external factor or some other freak cause could cause the argument to be null after being checked anyway? 2) What does it mean when exceptions should not be used to control the flow of programs and why not? I assume this is like: if (exceptionVariable != null) { } Is it generally good practise to fill every variable in an exception object? As a developer, do you expect every possible variable to be filled by another coder?

  • Storing data on SD Card in Android

    - by BBoom
    Using the guide at Android Developers (http://developer.android.com/guide/topics/data/data-storage.html) I've tried to store some data to the SD-Card. This is my code: // Path to write files to String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/"+ctxt.getString(R.string.package_name)+"/files/"; String fname = "mytest.txt"; // Current state of the external media String extState = Environment.getExternalStorageState(); // External media can be written onto if (extState.equals(Environment.MEDIA_MOUNTED)) { try { // Make sure the path exists boolean exists = (new File(path)).exists(); if (!exists){ new File(path).mkdirs(); } // Open output stream FileOutputStream fOut = new FileOutputStream(path + fname); fOut.write("Test".getBytes()); // Close output stream fOut.flush(); fOut.close(); } catch (IOException ioe) { ioe.printStackTrace(); } When I create the new FileOutputStream I get a FileNotFound exception. I have also noticed that "mkdirs()" does not seem to create the directory. Can anyone tell me what I'm doing wrong? I'm testing on an AVD with a 2GB sd card and "hw.sdCard: yes", the File Explorer of DDMS in Eclipse tells me that the only directory on the sdcard is "LOST.DIR".

  • Fast screen capture and lost Vsync

    - by user338759
    Hi, I'd like to generate a movie in real time with a self-made application doing fast screen captures with part of the screen occupied by a running 3D application. I'm aware that several applications already exist for this (like FRAPS or Taksi), and even dedicated DirectShow filters (like UScreenCapture), but i really need to make this with my own external application. When correctly setup (UScreenCapture + ffdshow), capturing an compressing a full screen does not consumes as much CPU as you would expect (about 15%), and does not impairs the performances of the 3D app. The problem of doing a capture from an external application is that the 3D application loses it's Vsync and creates a shaggy, difficult to use 3D application (3D app is only presented on a small part of the screen, the rest being GDI, DirectX) FRAPS solves this problem by allowing you to capture only one application at a time (the one with focus). Depending on the technology used (OpenGl, DirectX, GDI), it hooks the Vsync and does its capture (with glReadPixels,...), without perturbing it. Doing this does not solve my problem, since I want the full composed screen image (including 3D and the rest) AND a smooth 3D app. The UScreenCapture seems to use a fast DirectX call to capture the whole screen, but the openGL 3D app is still out of sync. Doing a BitBlt is too slow and CPU consumming to do real time 30 fps acquisition (at least under windows XP, not sure with 7) My question is to know if there is a way to achieve my goal with Windows 7 and it's brand new DirectX compositing engine? Windows 7 succeeds to show live VSynced duplicated previews of every app (in the taskbar), so there must be a way to access the currenlty displayed screen buffer without perturbing the rendering of the 3D OpenGL app ? Any other suggestion, technology ? thank you

  • Facebook XFBML IFrame App

    - by user329379
    Hi Guys, I started creating an application utilizing FBML but quickly realized its limits as far as external sources like javascript and so forth. I had just finished the app and now I am looking to convert it to XFBML so I can use external javascripts. I am having an issue with the login function. It allows a user to login when I goto my site but if i go to the facebook app page my button to login still appears in the frame (even though I am already logged into facebook). Upon clicking login the app fucntions as expected. My question is why do i have to click login even though I am already logged in? On the actual website it processes the app as if I am already logged in. Below is some of my code... $FB_APP_URL = 'http://apps.facebook.com/XXXXXX'; $facebook = new Facebook($api_key, $secret); $facebook-api_client-setFormat('json'); $user = $facebook-get_loggedin_user(); if (!$user) { $facebook->redirect($facebook->get_login_url($FB_APP_URL, 1)); } if (!$facebook-in_frame()) { $facebook-redirect($FB_APP_URL, 1); }

  • emacs tramp performance

    - by Oleg Pavliv
    Is there a way to improve emacs tramp performance? For me it's faster to open an external ftp client (filezilla), transfer files to the local disk and open them in an external editor (notepad) than open them with emacs. I use emacs23.1 under windows xp. I tried different tramp-default-method (telnet, pscp, ftp), all of them have the same performance. Profiling results with elp-instrument-package are the following (I opened 3 remote files of 1.5 MB each one) tramp-file-name-handler 1461 350.41599999 0.2398466803 tramp-sh-file-name-handler 1461 350.02699999 0.2395804243 tramp-send-command 227 179.63400000 0.7913392070 tramp-send-command-and-check 205 177.77600000 0.8672000000 tramp-wait-for-regexp 227 176.47800000 0.7774361233 tramp-wait-for-output 226 176.40000000 0.7805309734 tramp-barf-unless-okay 18 133.46699999 7.4148333333 tramp-handle-insert-file-contents 3 132.046 44.015333333 tramp-handle-file-local-copy 3 131.281 43.760333333 tramp-accept-process-output 2375 112.95100000 0.0475583157 So, actual file transfer takes 132 sec, about 1/3 of total time. Why does it spend so much time in tramp-sh-file-name-handler? I tried to advice a function tramp-sh-file-name-handler to store and return cached results but it does not work, probably this function has some side effects. Any ideas how to improve tramp performance? (I use emacs 23.1 under WindowsXP)

  • Retrieve parent node from selection (range) in Gecko and Webkit

    - by Jason
    I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

  • C# Static constructors design problem - need to specify parameter

    - by Neil Dobson
    I have a re-occurring design problem with certain classes which require one-off initialization with a parameter such as the name of an external resource such as a config file. For example, I have a corelib project which provides application-wide logging, configuration and general helper methods. This object could use a static constructor to initialize itself but it need access to a config file which it can't find itself. I can see a couple of solutions, but both of these don't seem quite right: 1) Use a constructor with a parameter. But then each object which requires corelib functionality should also know the name of the config file, so this has to be passed around the application. Also if I implemented corelib as a singleton I would also have to pass the config file as a parameter to the GetInstance method, which I believe is also not right. 2) Create a static property or method to pass through the config file or other external parameter. I have sort of used the latter method and created a Load method which initializes an inner class which it passes through the config file in the constructor. Then this inner class is exposed through a public property MyCoreLib. public static class CoreLib { private static MyCoreLib myCoreLib; public static void Load(string configFile) { myCoreLib = new MyCoreLib(configFile); } public static MyCoreLib MyCoreLib { get { return myCoreLib; } } public class MyCoreLib { private string configFile; public MyCoreLib(string configFile) { this.configFile = configFile; } public void DoSomething() { } } } I'm still not happy though. The inner class is not initialized until you call the load method, so that needs to be considered anywhere the MyCoreLib is accessed. Also there is nothing to stop someone calling the load method again. Any other patterns or ideas how to accomplish this?

  • Spell checker software

    - by Naren
    Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

  • Insert video clip in a lyx presentation and play it in GNU/Linux.

    - by Orjanp
    How can I insert a video clip into a presentation created in Lyx? Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player. I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer.

  • Maintaining a Python web application: heavier vs lighter framework?

    - by Tiberiu Ana
    Five+ years from now, you are hired to support and extend a data-centric web application written in Python that hasn't been kept up to date. Would you rather prefer it was written in the current version of Django/Pylons at the time, using the available standard components, or kept minimal with something like CherryPy/web.py and a few library dependencies? Heavy framework Advantages: standard approach to application design and structure, as encouraged by framework; less application code to worry about. Disadvantages: requires learning the framework to understand how things work; broken things in old version of framework difficult to fix; upgrading to new version potentially difficult due to changing APIs; finding relevant documentation/help potentially difficult due to changing APIs. Light framework Advantages: most application code is directly "visible"; only needed features are implemented; architecture should be simpler to understand; less need to upgrade external dependencies; easier to upgrade external dependencies. Disadvantages: some reinventing the wheel; non-standard design and structure (with the associated unique issues and bugs). I will update the list with any helpful answers.

We have a standard DMZ established that essentially has two firewalls. One that's external facing and the other that connects to the internal LAN. The following describes where each application tier is currently running. Outside the firewall: Silverlight Application In the DMZ: WCF Service (Business Logic & Data Access Layer) Inside the LAN: Database I'm receiving input that the architecture is not correct. Specifically, it has been suggested that because "a web server is easily hacked" that we should place a relay server inside the DMZ that communicates with another WCF service inside the LAN which will then communicate with the database. The external firewall is currently configured to only allow port 443 (https) to the WCF service. The internal firewall is configured to allow SQL connections from the WCF service in the DMZ. Ignoring the obvious performance implications, I don't see the security benefit either. I'm going to reserve my judgement of this suggestion to avoid polluting the answers with my bias. Any input is appreciated. Thanks, Matt

  • Maintaining session information between 2 asp.net calls programmatically?

    - by Santhosh
    Hi, I'm not sure if I'll be clear enough in my explaination to make you guys understand, but I'll try. Here's my problem: We have an external site which the users in our company connect to by giving their corresponding username and password. The external site is an ASP.NET website. We want to integrate this website into our intranet portal so that the users don't have to enter their UN/Pwd to login to the website. Since the target website has no provision for SSO, we are simulating the POST request to login. So far so good. We are now required to perform an action after the initial login is done, on an another page. We can simulate the corresponding POST request as well. But the problem is since we are not maintaining any session information in our initial POST request, it always redirects to the login screen! Is there any way to maintain ASP.NET session information between multiple calls done programmatically? Can we create an ASP.NET session id cookie programmatically and then pass it along with our initial request? Or this is not possible at all? Any comments are appreciated. Thanks for your help. Regards.

  • How do I get netcat to accept connections from outside the LAN?

    - by Chris
    I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?

  • How to suppress quotes in Powershell commands to executables

    - by David Gladfelter
    Is there any way to supress the enclosing quotation marks around each command-line argument that powershell likes to generate and then pass to external executables for command line arguments that have spaces in them? Here's the situation: One way to unpack many installers is a command of the form: msiexec /a <packagename> /qn TARGETDIR="<path to folder with spaces>" Trying to execute this from powershell has proven quite difficult. Powershell likes to enclose parameters with spaces in double-quotes. The following lines: msiexec /a somepackage.msi /qn 'TARGETDIR="c:\some path"' msiexec /a somepackage.msi /qn $('TARGETDIR="c:\some path"') $td = '"c:\some path"' msiexec /a somepackage.msi /qn TARGETDIR=$td All result in the following command line (as reported by the Win32 GetCommandLine() api): "msiexec" /a somepackage.msi /qn "TARGETDIR="c:\some path"" This command line: msiexec /a somepackage.msi TARGETDIR="c:\some path" /qn results in "msiexec" /a fooinstaller.msi "TARGETDIR=c:\some path" /qn It seems that Powershell likes to enclose the results of expressions meant to represent one argument in quotation marks when passing them to external executables. This works fine for most executables. However, MsiExec is very specific about the quoting rules it wants and won't accept any of the command lines Powershell generates for paths have have spaces in them. Is there any way to suppress this behavior?

  • Exporting static data in a DLL

    - by Gayan
    I have a DLL which contains a class with static members. I use __declspec(dllexport) in order to make use of this class's methods. But when I link it to another project and try to compile it, I get "unresolved external symbol" errors for the static data. e.g. In DLL, Test.h class __declspec(dllexport) Test{ protected: static int d; public: static void m(){} } In DLL, Test.cpp #include "Test.h" int Test::d; In the application which uses Test, I call m(). I also tried using __declspec(dllexport) for each method separately but I still get the same link errors for the static members. If I check the DLL (the .lib) using dumpbin, I could see that the symbols have been exported. For instance, the app gives the following error at link time: 1>Main.obj : error LNK2001: unresolved external symbol "protected: static int CalcEngine::i_MatrixRow" (?i_MatrixRow@CalcEngine@@1HA) But the dumpbin of the .lib contains: Version : 0 Machine : 14C (x86) TimeDateStamp: 4BA3611A Fri Mar 19 17:03:46 2010 SizeOfData : 0000002C DLL name : CalcEngine.dll Symbol name : ?i_MatrixRow@CalcEngine@@1HA (protected: static int CalcEngine::i_MatrixRow) Type : data Name type : name Hint : 31 Name : ?i_MatrixRow@CalcEngine@@1HA I can't figure out how to solve this. What am I doing wrong? How can I get over these errors? P.S. The code was originally developed for Linux and the .so/binary combination works without a problem

  • Selectively suppress XML comments?

    - by Mike Post
    We deliver a number of assemblies to external customers, but not all of the public APIs are officially supported. For example, due to less than optimal design choices sometimes a type must be publicly exposed from an assembly for the rest of our code to work, but we don't want customers to use that type. One part of communicating the lack of support is not provide any intellisense in the form of XML comments. Is there a way to selectively suppress XML comments? I'm looking for something other than ignoring warning 1591 since it's a long term maintenance issue. Example: I have an assembly with public classes A and B. A is officially supported and should have XML documentation. B is not intended for external use and should not be documented. I could turn on XML documentation and then suppress warning 1591. But when I later add the officially supported class C, I want the compiler to tell me that I've screwed up and failed to add the XML documentation. This wouldn't occur if I had suppressed 1591 at the project level. I suppose I could #pragma across entire classes, but it seems like there should be a better way to do this.
