• What does stdole.dll do?

  - by rc1

  We have a large C# (.net 2.0) app which uses our own C++ COM component and a 3rd party fingerprint scanner library also accessed via COM. We ran into an issue where in production some events from the fingerprint library do not get fired into the C# app, although events from our own C++ COM component fired and were received just fine. Using MSINFO32 to compare the loaded modules on a working system to those on a failing system we determined that this was caused by STDOLE.DLL not being in the GAC and hence not loaded into the faulty process. Dragging this file into the GAC caused events to come back fine from the fingerprint COM library. So what does stdole.dll do? It's 16k in size so it can't be much... is it some sort of link to another library like STDOLE32? How come its absence causes such odd behavior? How do we distribute stdole.dll? This is an XCOPY deploy app and we don't use the GAC. Should we package it as a resource and use the System.EnterpriseServices.Internal.Publish.GacInstall to ensure it's in the GAC?

• How do I stop cpan from reconfiguring each time? + More

  - by Leonard

  I'm running on a Mac (version 10.6.3) and am struggling to understand what is going on with my Perl installation. I let the system do a copy from my previous mac, and I appear to have a second perl installed, which appears earlier in my path. I can't tell (or remember) if I might have installed it with fink, macports or CPAN or what. type -a cpan cpan is /opt/local/bin/cpan cpan is /usr/bin/cpan I'm seeing two oddities. (To start with!) When I run cpan, and let it configure in ~lcuff/.cpan, each time I run it, it wants to reconfigure, giving the message: Sorry, we have to rerun the configuration dialog for CPAN.pm due to some missing parameters... Also, when I try to install File::Find::Rule (so I can list my CPAN modules, per the FAQ) I end up with an error message that I can't decipher or Google a solution for: Use of inherited AUTOLOAD for non-method Digest::SHA::shaopen() is deprecated at /opt/local/lib/perl5/vendor_perl/5.8.9/darwin-2level/Digest/SHA.pm line 55.

• python NameError: name '<anything>' is not defined (but it is!)

  - by BenjaminGolder

  Note: Solved. It turned out that I was importing a previous version of the same module. It is easy to find similar topics on StackOverflow, where someone ran into a NameError. But most of the questions deal with specific modules and the solution is often to update the module. In my case, I am trying to import a function from a module that I wrote myself. The module is named InfraPy, and it is definitely on sys.path. One particular function (called listToText) in InfraPy returns a NameError, but only when I try to import it into another script. Inside InfraPy, under if __name__=='__main__':, the listToText function works just fine. From InfraPy I can import other functions with no problems. Including from InfraPy import * in my script does not return any errors until I try to use the listToText function. How can this occur? How can importing one particular function return a NameError, while importing all the other functions in the same module works fine? Using python 2.6 on MacOSX 10.6, also encountered the same error running the script on Windows 7, using IronPython 2.6 for .NET 4.0 Thanks. If there are other details you think would be helpful in solving this, I'd be happy to provide them. As requested, here is the function definition inside of InfraPy: def listToText(inputList, folder=None, outputName='list.txt'): ''' Creates a text file from a list (with each list item on a separate line). May be placed in any given folder, but will otherwise be created in the working directory of the python interpreter. ''' fname = outputName if folder != None: fname = folder+'/'+fname f = open(fname, 'w') for file in inputList: f.write(file+'\n') f.close() This function is defined above and outside of if __name__=='__main__': I've tried moving InfraPy around in relation to the script. The most baffling situation is that when InfraPy is in the same folder as the script, and I import using from InfraPy import listToText, I receive this error: NameError: name listToText is not defined. Again, the other functions import fine, they are all defined outside of if __name__=='__main__': in InfraPy.

• FileNotFoundException, although the XML file should be deployed

  - by Bernhard V

  Hi, I've got problems starting my WAR application on a local JBoss. After two other EARs are deployed and the TomcatDeployer begins deploying the WAR, I'm getting the following error message: 2010-04-28 10:01:56,605 ERROR [org.jboss.ejb.plugins.LogInterceptor] [] [main] EJBException in method: public abstract at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenRemote at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy: javax.ejb.EJBException: org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition.

And at least I get a message that the deployment of the EAR has been successful. I also looked into the JAR with my file archiver and the ContextBasic.xml is indeed there at the right place. Is there a way for me to get sure that the JAR, not the EAR as a whole, is really deployed to the JBoss? I'm already starting to lose my head about this issue. Thank you. Bernhard

• What's the best way to develop a debugging window for an ajax ASP.Net MVC application

  - by KallDrexx

  While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

• Assigning specific menu administration rights for roles in drupal

  - by Martin Andersson

  Hello folks. I'm trying to give one of my roles the administrative rights to add/remove content in a specific menu (but not all menus). I think I found a module that should enable something like this, http://drupalmodules.com/module/delegate-menu-administration I've followed the instructions, added the role to my user, checked the "administer some menus" value for that role and checked the "Make admin" field for that role and specific menu in Menus. I also gave the role permissions to change page and story content. However, it still wont let the user add any new content it creates in any menu, and I get an error message saying "warning: Invalid argument supplied for foreach() in /home/martin/www/drupal/modules/delegate_menu_admin/delegate_menu_admin.module on line 346." Line 346 looks like this: foreach ($form['menu']['parent']['#options'] as $key => $value) { I did a print_r($form); in the file just before it and there's no such array that I can see: [menu] => Array ( [#access] => 1 [delete] => Array ( [#access] => ) ) When I gave the role "administer menu" permissions, nothing extra was printed at all, leading me to the assumption that the delegate_menu_admin.module file is not used at all while both the "administer menu" and the "administer some menus" (from the delegate-menu-administration module) permissions are set! Is this some incompatibility between the module because of some drupal update? Or am I just too tired and too stupid? :)

• Mysqli query only works on localhost, not webserver

  - by whamo

  Hello. I have changed some of my old queries to the Mysqli framework to improve performance. Everything works fine on localhost but when i upload it to the webserver it outputs nothing. After connecting I check for errors and there are none. I also checked the php modules installed and mysqli is enabled. I am certain that it creates a connection to the database as no errors are displayed. (when i changed the database name string it gave the error) There is no output from the query on the webserver, which looks like this: $mysqli = new mysqli("server", "user", "password"); if (mysqli_connect_errno()) { printf("Can't connect Errorcode: %s\n", mysqli_connect_error()); exit; } // Query used $query = "SELECT name FROM users WHERE id = ?"; if ($stmt = $mysqli->prepare("$query")) { // Specify parameters to replace '?' $stmt->bind_param("d", $id); $stmt->execute(); // bind variables to prepared statement $stmt->bind_result($_userName); while ($stmt->fetch()) { echo $_userName; } $stmt-close(); } } //close connection $mysqli-close(); As I said this code works perfectly on my localserver just not online. Checked the error logs and there is nothing so everything points to a good connection. All the tables exists as well etc. Anyone any ideas because this one has me stuck! Also, if i get this working, will all my other queries still work? Or will i need to make them use the mysqli framework as well? Thanks in advance.

• How do I begin reading source code?

  - by anonnoir

  I understand the value of reading source code, and I am trying my best to read as much as I can. However, every time I try getting into a 'large' (i.e. complete) project of sorts, I am overwhelmed. For example, I use Anki a lot when revising languages. Also, I'm interested in getting to know how an audio player works (because I have some project ideas), hence quodlibet on Google Code. But whenever I open the source code folders for the above programs, there are just so many files that I don't know where or what to begin with. I think that I should start with files marked init.py but I can't see the logical structure of the programs, or what reasoning was applied when the original writer divided his modules the way he did. Hence, my questions: How/where should I begin reading source? Any general tips or ideas? How does a programmer keep in mind the overall structure and logic of the program, especially for large projects, and is it common not to document that structure? As an open source reader, must I look through all of the code and get a bird's eye view of the code and libraries, before even being able to proceed? Would an IDE like Eclipse SDK (with PyDev) help with code-reading? Thanks for the help; I really appreciate your helping me.

• git clone fails with "index-pack" failed?

  - by gct

  So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

• Handling incremental Data Modeling Changes in Functional Programming

  - by Adam Gent

  Most of the problems I have to solve in my job as a developer have to do with data modeling. For example in a OOP Web Application world I often have to change the data properties that are in a object to meet new requirements. If I'm lucky I don't even need to programmatically add new "behavior" code (functions,methods). Instead I can declarative add validation and even UI options by annotating the property (Java). In Functional Programming it seems that adding new data properties requires lots of code changes because of pattern matching and data constructors (Haskell, ML). How do I minimize this problem? This seems to be a recognized problem as Xavier Leroy states nicely on page 24 of "Objects and Classes vs. Modules" - To summarize for those that don't have a PostScript viewer it basically says FP languages are better than OOP languages for adding new behavior over data objects but OOP languages are better for adding new data objects/properties. Are there any design pattern used in FP languages to help mitigate this problem? I have read Phillip Wadler's recommendation of using Monads to help this modularity problem but I'm not sure I understand how?

• Integrating Magento with SAP ECC 6.0 Backend

  - by ikarous

  I'm a freshly graduated (read: inexperienced) developer who's been tasked with determining the feasibility of integrating Magento with an SAP-based backend. No developer at our company has any experience working with either SAP or Magento, so I was hoping that the Stack Overflow community may be able to point me in the right direction with my research. We're a small company (four full-time developers) and the timeline on this project would be tight, so I'm trying to gather as much information as possible. The client has a tiered pricing structure, tax calculation logic, promotional deals, and automatic freight determination all implemented in an SAP ECC 6.0 system. They would like to migrate all their online stores over to Magento while continuing to utilize all existing functionality in SAP. The idea is to accomplish this by overriding certain modules in Magento to place remote calls to SAP BAPIs. I've investigated SAPRFC, which looks promising but relatively stale in terms of update frequency. Do any developers have experience using SAPRFC with SAP ECC 6.0 (with or without Magento integration)? If so, what were your experiences, and what were the biggest risk factors involved? Any comments, suggestions, or links to resources would be greatly appreciated.

• What's the purpose of "import package"?

  - by codethief

  As I just found out import package does not make the package's modules available through package.module. The same obviously holds true for from package import subpackage as well as from package import * What's the purpose of importing a package at all then if I can't access its submodules but only the objects defined in __init__.py? It makes sense to me that from package import * would bloat the namespace, which, however, doesn't apply in case of the other two ways! I also understand that loading all submodules might take a long time. But I don't know what these unwanted side-effects, "that should only happen when the sub-module is explicitly imported", are which the author of the previous link mentions. To me it looks like doing an import package[.subpackage] (or from package import subpackage) makes absolutely no sense if I don't exactly want to access objects provided in __init__.py. Are those unwanted side effects really that serious that the language actually has to protect the programmer from causing them? Actually, I thought that Python was a little bit more about "If the programmer wants to do it, let him do it." In my case, I really do want to import all submodules with the single statement from package import subpackage, because I need all of them! Telling Python in the init.py file which submodules I'm exactly talking about (all of them!) is quite cumbersome from my point of view. Please enlighten me. :)

• SignalR - Handling disconnected users

  - by guilhermeGeek

  Hy, I'm using the signalR library on a project to handle an notification and chat modules. I've a table on an database to keep a track of online users. The HUB for chat is inheriting IDisconnect where i disconnect the user. After disconnecting the user, i warm the users about that event. At this point, i check if the disconnect user is the client. If it's, then i call an method on HUB to reconnect the user (just update the table). I do this because with the current implementation, once the user closes a tab on the browser it calls the Disconnect task but he could have another tab opened. I've not tested (with larger requests) this module yet, but on my development server it could take a few seconds between the IDisconnect event, and the request from the user to connect again. I'm concerned with my implementation to handle disconnected users from the chat but i can't see another way to improve this. If possible, could someone give me a advice on this, or this is the only solution that i've?

• Using perl to split a line that may contain whitespace

  - by Tommy Fisk

  Okay, so I'm using perl to read in a file that contains some general configuration data. This data is organized into headers based on what they mean. An example follows: [vars] # This is how we define a variable! $var = 10; $str = "Hello thar!"; # This section contains flags which can be used to modify module behavior # All modules read this file and if they understand any of the flags, use them [flags] Verbose = true; # Notice the errant whitespace! [path] WinPath = default; # Keyword which loads the standard PATH as defined by the operating system. Append with additonal values. LinuxPath = default; Goal: Using the first line as an example "$var = 10;", I'd like to use the split function in perl to create an array that contains the characters "$var" and "10" as elements. Using another line as an example: Verbose = true; # Should become [Verbose, true] aka no whitespace is present This is needed because I will be outputting these values to a new file (which a different piece of C++ code will read) to instantiate dictionary objects. Just to give you a little taste of what it might look like (just making it up as I go along): define new dictionary name: [flags] # Start defining keys => values new key name: Verbose new value val: 10 # End dictionary Oh, and here is the code I currently have along with what it is doing (incorrectly): sub makeref($) { my @line = (split (/=/)); # Produces ["Verbose", " true"]; }

• Django Threaded Commenting System

  - by Yasin Ozel

  (and sorry for my english) I am learning Python and Django. Now, my challange is developing threaded generic comment system. There is two models, Post and Comment. -Post can be commented. -Comment can be commented. (endless/threaded) -Should not be a n+1 query problem in system. (No matter how many comments, should not increase the number of queries) My current models are like this: class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() child = generic.GenericRelation( 'Comment', content_type_field='parent_content_type', object_id_field='parent_object_id' ) class Comment(models.Model): content = models.TextField() child = generic.GenericRelation( 'self', content_type_field='parent_content_type', object_id_field='parent_object_id' ) parent_content_type = models.ForeignKey(ContentType) parent_object_id = models.PositiveIntegerField() parent = generic.GenericForeignKey( "parent_content_type", "parent_object_id") Are my models right? And how can i get all comment (with hierarchy) of post, without n+1 query problem? Note: I know mttp and other modules but I want to learn this system. Edit: I run "Post.objects.all().prefetch_related("child").get(pk=1)" command and this gave me post and its child comment. But when I wanna get child command of child command a new query is running. I can change command to ...prefetch_related("child__child__child...")... then still a new query running for every depth of child-parent relationship. Is there anyone who has idea about resolve this problem?

• Perl: Process Communcation

  - by Shiftbit

  Can anyone explain how I can successfully get my process communicating. I find the perldoc on IPC confusing. What I have so far is: $| = 1; $SIG{CHLD} = {wait}; my $parentPid = $$; if ($pid = fork();) ) { if ($pid == 0) { pipe($parentPid, $$); open PARENT, "<$parentPid"; while (<PARENT>) { print $_; } close PARENT; exit(); } else { pipe($parentPid, $pid); open CHILD, ">$pid"; or error("\nError opening: childPid\nRef: $!\n"); open (FH, "<list") or error("\nError opening: list\nRef: $!\n"); while(<FH>) { print CHILD, $_; } close FH or error("\nError closing: list\nRef: $!\n"); close CHILD or error("\nError closing: childPid\nRef: $!\n); } else { error("\nError forking\nRef: $!\n"); } First Question is what does Perldoc pipe mean by READHANDLE, WRITEHANDLE? Second Questions is can I implement a solution without relying on CPAN or other modules?

• Using Mod-Rewrite in XAMPP

  I've followed some tutorials on how to use Mod_Rewrite, but it's not working out. I have a php index page that takes a page parameter like so: call: index?page=name1, name2, name3 etc. <?php if (isset($_GET['page'])) { switch($_GET['page']) { case 'front': include "front.php"; break; default: break; } } ?

• mod_cgi , mod_fastcgi, mod_scgi , mod_wsgi, mod_python, FLUP. I don't know how many more. what is mo

  - by claws

  I recently learnt Python. I liked it. I just wanted to use it for web development. This thought caused all the troubles. But I like these troubles :) Coming from PHP world where there is only one way standardized. I expected the same and searched for python & apache. http://stackoverflow.com/questions/449055/setting-up-python-on-windows-apache says Stay away from mod_python. One common misleading idea is that mod_python is like mod_php, but for python. That is not true. So what is equivalent of mod_php in python? I need little clarification on this one http://stackoverflow.com/questions/219110/how-python-web-frameworks-wsgi-and-cgi-fit-together CGI, FastCGI and SCGI are language agnostic. You can write CGI scripts in Perl, Python, C, bash, or even Assembly :). So, I guess mod_cgi , mod_fastcgi, mod_scgi are their corresponding apache modules. Right? WSGI is some kind of optimized/improved inshort an efficient version specifically designed for python language only. In order to use this mod_wsgi is a way to go. right? This leaves out mod_python. What is it then? Apache - mod_fastcgi - FLUP (via CGI protocol) - Django (via WSGI protocol) Flup is another way to run with wsgi for any webserver that can speak FCGI, SCGI or AJP What is FLUP? What is AJP? How did Django come in the picture? These questions raise quetions about PHP. How is it actually running? What technology is it using? mod_php & mod_python what are the differences? In future if I want to use Perl or Java then again will I have to get confused? Kindly can someone explain things clearly and give a Complete Picture.

• Getting a "No default module defined for this application" exception while running controller unit t

  - by Doron

  I have an application with the default directory structure, for an application without custom modules (see structure figure at the end). I have written a ControllerTestCase.php file as instructed in many tutorials, and I've created the appropriate bootstrap file as well (once again, see figures at the end). I've written some model tests which run just fine, but when I started writing the index controller test file, with only one test in it, with only one line in it ("$this-dispatch('/');"), I'm getting the following exception when running phpunit (but navigating with the browser to the same location - all is good and working): 1) IndexControllerTest::test_indexAction_noParams Zend_Controller_Exception: No default module defined for this application Why is this ? What have I done wrong ?

• AJAX Partial Rendering issues for the default page in IIS 7 when using custom http module

  - by WiseGuyEh

  The problem When I try to make a AJAX partial update request (using the UpdatePanel control) from the default page of an IIS7 web site, it fails- instead of returning the html to be updated, it returns the entire page, which then causes the MS AJAX Javascript to throw a parsing shit-fit. The suspected cause I have narrowed the cause down to two issues- making an AJAX request to the default page when I have a certain custom http module registered. A partial rendering request to http://localhost will fail, but a partial rendering request to http://localhost/default.aspx will work fine. Also, If i remove the following line in my custom HttpModule: _application.PreRequestHandlerExecute += OnPreRequestHandlerExecute; The AJAX partial render will work correctly. Wierd huh? Another wierd thing... If I look at trace.axd, I can see that when a partial rendering request fails, two POST requests are logged for the one partial rendering request- one where the default.aspx page executes successfully (trace information such as page_load is logged) but no content is produced and a second that doesn't seem to actually execute (no trace information is logged) but produces content (HTTP_CONTENT_LENGTH is greater than 0). Please help! If anyone with a good knowledge of HTTP modules or the MS AJAX Http module could explain why this is occuring I would be very grateful. As it is, the obvious work arround is to just redirect to default.aspx if the request url is "/" but I would really like to understand why this is occurring.

• What options to parse a DTD using PHP

  - by Chadwick

  I need to parse DTDs using PHP and am hoping there's a simple library to help out. Each DTD has numerous <!ENTITY... and <!-- Comment... elements, which I need to act upon. Note that I do not need to validate anything against these DTDs, simply parse them as data files themselves. A few options I've looked at: James Clarke's SD, which is an option of last resort, but I'd like to avoid the complexity of building/installing/configuring code external to PHP. I'm not sure it's even possible in my situation. PEAR has an XML_DTD_Parser, which requires installing/configuring PEAR and a number of pear modules, which I'm also not sure is possible, and would rather avoid. Has anyone used it with success? PHP XML Classes has the class_path_parser, which another site suggested, but it fails to read ENTITY elements. It appears to be using PHP's built in XML parsing capabilities, which use EXPAT. PHP's DOMDocument will validate against a DTD, so must be able to read them, though I don't see how to get at the DTD parser directly at first glance.

• Writing fortran robust and "modern" code

  - by Blklight

  In some scientific environments, you often cannot go without FORTRAN as most of the developers only know that idiom, and there is lot of legacy code and related experience. And frankly, there are not many other cross-platform options for high performance programming ( C++ would do the task, but the syntax, zero-starting arrays, and pointers are too much for most engineers ;-) ). I'm a C++ guy but I'm stuck with some F90 projects. So, let's assume a new project must use FORTRAN (F90), but I want to build the most modern software architecture out of it. while being compatible with most "recent" compilers (intel ifort, but also including sun/HP/IBM own compilers) So I'm thinking of imposing: global variable forbidden, no gotos, no jump labels, "implicit none", etc. "object-oriented programming" (modules with datatypes + related subroutines) modular/reusable functions, well documented, reusable libraries assertions/preconditions/invariants (implemented using preprocessor statements) unit tests for all (most) subroutines and "objects" an intense "debug mode" (#ifdef DEBUG) with more checks and all possible Intel compiler checks possible (array bounds, subroutine interfaces, etc.) uniform and enforced legible coding style, using code processing tools C stubs/wrappers for libpthread, libDL (and eventually GPU kernels, etc.) C/C++ implementation of utility functions (strings, file operations, sockets, memory alloc/dealloc reference counting for debug mode, etc.) ( This may all seem "evident" modern programming assumptions, but in a legacy fortran world, most of these are big changes in the typical programmer workflow ) The goal with all that is to have trustworthy, maintainable and modular code. Whereas, in typical fortran, modularity is often not a primary goal, and code is trustworthy only if the original developer was very clever, and the code was not changed since then ! (i'm a bit joking here, but not much) I searched around for references about object-oriented fortran, programming-by-contract (assertions/preconditions/etc.), and found only ugly and outdated documents, syntaxes and papers done by people with no large-scale project involvement, and dead projects. Any good URL, advice, reference paper/books on the subject?

• "ImportError: cannot import name Exchange" when using Celery w/ Kombu installed

  - by alukach

  I'm trying to create a Celery worker node on an Amazon EC2 Windows2008 R2 instance. Due to a plugin we require for another Python module, we are required to user Python3. I've installed Python3.2 and necessary modules and run Celery, but for some reason it states that it can't import Exchange and Queue from Kombu, despite the face that Kombu is installed and can be imported by python.
