• Reflection and Operator Overloads in C#

  - by TenshiNoK

  Here's the deal. I've got a program that will load a given assembly, parse through all Types and their Members and compile a TreeView (very similar to old MSDN site) and then build HTML pages for each node in the TreeView. It basically takes a given assembly and allows the user to create their own MSDN-like library for it for documentation purposes. Here's the problem I've run into: whenever an operator overload is encounted in a defined class, reflection returns that as a "MethodInfo" with the name set to something like "op_Assign" or "op_Equality". I want to be able to capture these and list them properly, but I can't find anything in the MethodInfo object that is returned to accurately identify that I'm looking at an operator. I definitely don't want to just capture everything that starts with "op_", since that will most certainly (at some point) will pick up a method it's not supposed to. I know that other methods and properties that are "special cases" like this one have the "IsSpecialName" property set, but appearantly that's not the case with operators. I've been scouring the 'net and wracking my brain to two days trying to figure this one out, so any help will be greatly appreciated.

• How to get a checkout-able revision info from subversion?

  - by zhongshu

  I want to check a svn url and to get the latest revision, then checkout it, I don't want to use HEAD because I will compare the latest revision to others. so I use "svn info" to get the "Last Changed Rev" for the url like this: D:\Project>svn info svn://.../branches/.../path Path: ... URL: svn://.../branches/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2400 Node Kind: directory Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 but, I found the 2396 revision is not checkout-able, because this path is in a branch copied from trunk, and the 2396 is the revision modified in the trunk. so when I use svn checkout -r 2396, I will get a workcopy for the path in the trunk, then I can not do checkin for the branch. D:\Project>svn checkout svn://.../branches/.../path -r 2396 workcopy ..... ..... D:\Project>svn info workcopy Path: workcopy URL: svn://.../trunk/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2396 Node Kind: directory Schedule: normal Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 So, my question is how to get a checkout-able revision for the branch path, for this example, I want to get 2397 (because 2397 is the revision which copy occur). And I know "svn log" can get the info, but "svn log" output maybe very long and parse it will be difficult than "svn info". I just want know which revision is the latest checkout-able revision for the path.

• Cross-platform build UNC share (Windows->Linux) - possible to be case-sensitive on CIFS share?

  - by holtavolt

  To optimize builds between Windows and Linux (Ubuntu 10.04), I've got a UNC share of the source tree that is shared between systems, and all build output goes to local disk on each system. This mostly works great, as source updates and changes can quickly be tested on both systems, but there's one annoying limitation I can't find a way around, which is that the Linux CIFS mount is case-insensitive. Consequently, a test compile of code that has an error like: #include "Foo.h" for a file foo.h, will not be caught by a test build (until a local compile is done on the Linux box, e.g. nightly builds) Is it possible to have case-sensitivity of the Windows UNC share on the Linux box? I've tried a variety of fstab and mount combinations with no success, as well as editing the smb.config to set "case sensitive = yes" Given what the Ubuntu man page info states on this: nocase Request case insensitive path name matching (case sensitive is the default if the server suports it). I suspect that this is a limitation from the Windows UNC side, and there's nothing to be done short of switching to some other mechanism (is NFS still viable anywhere?) If anyone has already solved this to support optimized cross-platform build environments, I'd appreciate hearing about it!

• Is this XML file correct for RSS feeding?

  - by Hermet

  Hi guys I am generating a XML-RSS type file from PHP. The output for example is like this <?xml version="1.0" encoding="iso-8859-1"?> <rss version="2.0"> <channel> <title>Mi web mola</title> <link>http://www.dominio.com/blog.php</link> <language>es-ES</language> <description>Mallas y eso</description> <generator>Autor</generator> <item> <title>Articulo de prueba</title> <link>http://www.midominio.com/2342</link> <pubDate>14/06/2010</pubDate> <description><![CDATA[Descripcion de prueba bla bla bla]]></description> <content:encoded><![CDATA[Contenido prueba]]></content:encoded> </item> </channel> </rss> ... and all I can see in the Firefox preview is the title and the description of the blog, not the items, but in the source it appears correctly, so I've thought it must be a parse error or something like that.. What could be wrong? Again, excuse me for my bad english, and thank you very much.

• Simple jQuery syntax help, don't know where I've gone wrong

  - by Jascination

  I'm having trouble with a jQuery code at the moment, I know WHERE the problem lies, but I don't know what the problem is exactly. Probably very basic, but I'm new to this. You can see a (non)working fiddle here: http://www.jsfiddle.net/CvZeQ/ Basically I want to set different .click function based on whatever is selected (I have 5 image maps, each with a different #mapname, and want each to pertain to a different variable (answer1, answer2, answer3...) so as to store the selected 'answer' for each map.) Here is the code I'm using for one of the maps: $(window).load(function(){ //Get cookies when page loaded var useranswers=$.cookie('survery'); useranswers= JSON.parse (useranswers); // do something with previous answers //#shape functions $('#shape area').hover( function(e){ $('#'+ this.alt).addClass('hover'); }, function(e){ $('#'+ this.alt).removeClass('hover'); } ).click( function(e){ $('img.selected-region').removeClass('selected-region'); }, function(e){ $('#'+ this.alt).addClass('selected-region'); }, function(e){ var answer1 = $(this).attr("class"); }); }); I know the problem lies somewhere with the .click function, but I'm not entirely sure what I've done wrong. Any help would be greatly appreciated.

• local vs core contoller

  - by latvian

  Hi, I am adding new column and action in the local admin app/code/local/Mage/Adminhtml/Block/Catalog/Product/Grid.php which works fine, however. The local controller/app/code/local/Mage/Adminhtml/Block/Catalog/Product.php is not being used or is not overloading the admin one /app/code/core/Mage/Adminhtml/Block/Catalog/Product.php. This is almost fresh install of Magento 1.4.0.1. I am the only one working, so i know it is not overloaded by some custom controller. I have disabled all custom modules. I have rolled back most of my changes. I have checked /etc/Modules/Mage_Catalog.xml. Refreshed cache all possible ways, loged in and out. Nothing....still using the core contoller copy. why? How do you troubleshoot, meaning, at what moment magento decides using between core or local copies? ...its even more strange because it does not parse local Adminhtml config.xml but uses local Adminthml copy of Blocks. Any pointer would help. I would like to keep everything in local code. Thank You, Margots

• Python script to delete old SVN files lacks permission

  - by Rosarch

  I'm trying to delete old SVN files from directory tree. shutil.rmtree and os.unlink raise WindowsErrors, because the script doesn't have permissions to delete them. How can I get around that? Here is the script: # Delete all files of a certain type from a direcotry import os import shutil dir = "c:\\" verbosity = 0; def printCleanMsg(dir_path): if verbosity: print "Cleaning %s\n" % dir_path def cleandir(dir_path): printCleanMsg(dir_path) toDelete = [] dirwalk = os.walk(dir_path) for root, dirs, files in dirwalk: printCleanMsg(root) toDelete.extend([root + os.sep + dir for dir in dirs if '.svn' == dir]) toDelete.extend([root + os.sep + file for file in files if 'svn' in file]) print "Items to be deleted:" for candidate in toDelete: print candidate print "Delete all %d items?

• Edit Settings in web.config

  - by Scott Selby

  I didn't know how to title this question - I am making a request to PayPal's Express Payment API. I am using their dll that helps make the request and parse the response. The instructions for their code to work is to add you authorization credentials in the web.config file. I have done so. My problem is that I want to be able to edit these credentials that are being set dynamically ( probably get from SQL ) because we are going to allow different users to enter their API credentials. Sending the request to PayPal looks like this Dim wrapper As New SetExpressCheckoutReq() wrapper.SetExpressCheckoutRequest = request Dim service As New PayPalAPIInterfaceServiceService() Dim setECResponse As SetExpressCheckoutResponseType = service.SetExpressCheckout(wrapper) There's not much room in there to edit the header of the request , because PayPalAPIInterfaceServiceService() is defined in their dll and applies its own header based on the credentials in the web.config. So, my question is , is there a way to point in the web.config to another location when it looks in web.config? I'm not to sure this is possible , also is there any way to edit the header of a request that is defined in a dll without changing the dll (to stay pci compliant) The line in the web.config is here: <account apiUsername="****" apiPassword="****" apiSignature="****"/>

• .net printing multiple reports in one document (architecture question)

  - by LawsonM

  I understand how to print a single document via the PrintDocument class. However, I want to print multiple reports in one document. Each "report" will consist of charts, tables, etc. I want to have two reports per page. I've studied the few examples I can find on how to combine multiple documents into one; however, they always seem to work by creating a collection of objects (e.g. customer or order) that are then iterated over and drawn in the OnPrintPage method. My problem and hence the "architecture" question is that I don't want to cache the objects required to produce the report since they are very large and memory intensive. I'd simply like the resulting "report". One thought I had was to print the report to a metafile, cache that instead in a "MultiplePrintDocument" class and then position those images appropriately two to a page in the OnPrintPage method. I think this would be a lot more efficient and scalable in my case. But I'm not a professional programmer and can't figure out if I'm barking up the wrong tree here. I think the Graphics.BeginContainer and Graphics.Save methods might be relevant, but can't figure out how to implement or if there is a better way. Any pointers would be greatly appreciated.

• Parsing localized date strings in PHP

  - by Mikeage

  Hi, I have some code (it's part of a wordpress plugin) which takes a text string, and the format specifier given to date(), and attempts to parse it into an array containing hour, minute, second, day, month, year. Currently, I use the following code (note that strtotime is horribly unreliable with things like 01/02/03) // $format contains the string originally given to date(), and $content is the rendered string if (function_exists('date_parse_from_format')) { $content_parsed = date_parse_from_format($format, $content); } else { $content = preg_replace("([0-9]st|nd|rd|th)","\\1",$content); $content_parsed = strptime($content, dateFormatToStrftime($format)); $content_parsed['hour']=$content_parsed['tm_hour']; $content_parsed['minute']=$content_parsed['tm_min']; $content_parsed['day']=$content_parsed['tm_mday']; $content_parsed['month']=$content_parsed['tm_mon'] + 1; $content_parsed['year']=$content_parsed['tm_year'] + 1900; } This actually works fairly well, and seems to handle every combination I've thrown at it. However, recently someone gave me 24 ??????, 2010. This is Russian for November 24, 2010 [the date format was j F, Y], and it is parsed as year = 2010, month = null, day = 24. Are there any functions that I can use that know how to translate both November and ?????? into 11? EDIT: Running print_r(setlocale(LC_ALL, 0)); returns C. Switching back to strptime() seems to fix the problem, but the docs warn: Internally, this function calls the strptime() function provided by the system's C library. This function can exhibit noticeably different behaviour across different operating systems. The use of date_parse_from_format(), which does not suffer from these issues, is recommended on PHP 5.3.0 and later. Is date_parse_from_format() the correct API, and if so, how do I get it to recognize the language?

• [javascript] Populating jsTree based on XML data uploaded to server folder

  - by PFM

  tl:dr How can I populate jsTree based on a folder location instead of an exact XML url? I'm looking for a little direction on this project. Currently I am trying to copy file structures of hard drives as XML files and recreate them using jsTree on the webserver for a completely independent version of the file structure. I have some python script that outputs XML files that are formed to jsTree and automatically uploads to a folder on the server. The problem is now I am a little lost because I have to manually enter each XML file into jsTree code for it to display so I have multiple entries like this: $("#tree1") .jstree({ "plugins" : [ "themes", "xml_data", "ui", "search", "types" ], "xml_data" : { "ajax" : { "url" : "./XML_DATA/DRIVE1.xml" }, "xsl" : "nest" }, I see in the documentation that instead of populated by the direct file the folders are populated by "server.php" but no where in the php code does it point to any directories or files. After considering the problem I thought of a few solutions and could use some advice on them: Should I be trying to write php code to automatically look through my XML_DATA folder to upload each XML file? Should I just upload all the XML to mySQL and populate my tree based on that? Should the javascript be the code looking through the server's folder for XML files? All the XML is formed the same way but the number of XML files on the server will increase and will have to be refreshed as well as they will be overwritten with changes. Any direction would be appreciated, thanks.

• Simple HTML interface to XSD?

  - by Visage

  I'm writing an app that, at its heart, uses a hierarchical tree of nodes in XML, it looks like this: <node> <name>Node1</name> <Attribute1>Something</Attribute1> <Attribute2>SomethingElse</Attribute2> <child>Node2</child> <child>Node4</child> <child>Node7</child> </node> And so on (all child elements must refer to an existing node, though the node inquestion doesnt have to precede the first reference to it) For a simple structure like this is there a simple tool to generate a html page that will allow a user to enter Nodes and dynamically update a server-side xml file? Im basically writing a tool that will use such a file, but the people who's job it is to create the file arent especially techno-literate, so creating the XML by hand is a no-no. I could hand-crank one fairly quickly, but if I can get a tool to do it, even better (especially as the format may change in future)....

• How do I cover unintuitive code blocks?

• How can multiple variables be passed to a function cleanly in C?

  - by aquanar

  I am working on an embedded system that has different output capabilities (digital out, serial, analog, etc). I am trying to figure out a clean way to pass many of the variables that will control those functions. I don't need to pass ALL of them too often, but I was hoping to have a function that would read the input data (in this case from a TCP network), and then parse the data (IE, the 3rd byte contains the states of 8 of the digital outputs (according to which bit in that byte is high or low)), and put that into a variable where I can then use elsewhere in the program. I wanted that function to be separate from the main() function, but to do so would require passing pointers to some 20 or so variables that it would be writing to. I know I could make the variables global, but I am trying to make it easier to debug by making it obvious when a function is allowed to edit that variable, by passing it to the function. My best idea was a struct, and just pass a pointer to it, but wasn't sure if there was a more efficient way, especially since there is only really 1 function that would need to access all of them at once, while most others only require parts of the information that will be stored in this bunch of state variables. So anyway, is there a clean way to send many variables between functions at once that need to be edited?

• Resumable Upload in Ruby on Rails

  - by user253011

  Hi, I have been searching for a way for resumable file upload in RoR. In conclusion, I found out other than Java Applet no client-side-and-cross-platform agent can access the file system in such a way that to request the file from the position where the upload got terminated (due to any reason) with some exceptions like http://github.com/taf2/resume-up/tree/master (built in native Ruby, but requires google gears which is not "reliable" yet when it comes to cross platform almost same story as of ActiveX!) Since the only reliable option left is java applet, is there any good tutorial/forum/documentation for those paid java applets, such as "thin slice upload" etc. to make it work with rails application. I have found one http : // github . com / dassi / mediaclue , its a non-multi-ligual-German-Application in which they used jumploader. But in that application, I am unable to see resumable functionality. Scratching my head against their documentation, i found out http : // jumploader.com / doc_resume.html It tells that jumploader has resume functionality in Cross session resume, the one i am looking for (if the user close the browser the new session gets hold on uncompleted uploaded files from the old session against the user id). But I cant find any example on their demos page which actually pause/RESUME functionality in a continuous manner! Is it even possible to achieve that kind of resumable functionality. Please tell me about any options/example/demos preferable deployed in rails. I shall be very much obliged. ~ Thanks

• Android while getting HTTP response to file how to know it wasn't fully loaded?

  - by Stan

  I'm using this approach to store a big-sized response from server to parse it later: final HttpClient client = new DefaultHttpClient(new BasicHttpParams()); final HttpGet mHttpGetRequest = new HttpGet(strUrl); mHttpGetRequest.setHeader("Content-Type", "application/x-www-form-urlencoded"); FileOutputStream fos = null; try { final HttpResponse response = client.execute(mHttpGetRequest); final StatusLine statusLine = response.getStatusLine(); lastHttpErrorCode = statusLine.getStatusCode(); lastHttpErrorMsg = statusLine.getReasonPhrase(); if (lastHttpErrorCode == 200) { HttpEntity entity = response.getEntity(); fos = new FileOutputStream(reponseFile); entity.writeTo(fos); entity.consumeContent(); fos.flush(); } } catch (ClientProtocolException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (final ParseException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (final UnknownHostException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (IOException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); } finally{ if (fos!=null) try{ fos.close(); } catch (IOException e){} } now how could I ensure the response was completely received and thus saved to file? Assume client's device lost Internet connection while this code was running. So the app received only some part of real response. And I'm pretty sure it happens cuz I got parsing exceptions like "tag not closed", "unexpected end of file" etc. So I need to detect somehow this situation to prevent code from parsing partial response but can't see how. Is it possible at all and how to do it? Or has it has to raise IOException in such cases?

• How combine TabBar + Navigation with XCode

  - by mamcx

  I'm triying to combine a TabBar + Navigation app. I have 5 tab bars, 4 are listing of stuff and drill down to details views. I try to follow this tutorial: http://www.iphonedevforums.com/forum/iphone-sdk-development/124-view-controller-problem.html But always get a blank view. This is what I do, with a clean project: I start with a TabBar template app. I put 5 tab bar buttons. I create a controller like: @interface FirstViewController : UINavigationController { } I put the main window.xib on tree mode & change the selected first view to FirstViewController I select the TabBar Controller in Interface builder, go to TabBar Attributes & change the class to navigation controler. Select the fist view & put the nib name "SecondView" In response, I get a blank screen. I must add that I wanna navigate from the details views, no from the main windows. i.e in the main window tab bar 1 is the list of people. I select a person then wanna navigate to the detail window.

• How can I get a Node adjacent to a unique Node using Scala?

  - by pr1001

  I'm trying to parse an Apple plist file and I need to get an array Node within it. Unfortunately its only unique identifier is sibling Node right before it, <key>ProvisionedDevices</key>. Right now my best thoughts are to use Java's XPATH querying or Node.indexOf. Here is an example: <plist version="1.0"> <dict> <key>ApplicationIdentifierPrefix</key> <array> <string>RP8CBF4MRE</string> </array> <key>CreationDate</key> <date>2010-05-10T11:44:35Z</date> <key>DeveloperCertificates</key> <array> ... <key>ProvisionedDevices</key> <array> ... // I need the Nodes here </array> </dict> </plist> Thanks!

• Memory not being returned after function python call

  - by Dan

  I've got a function which does a parse of a sentence by building up a big chart. For some reason, Python holds on to whatever memory was allocated during that function call. That is, I do best = translate(sentence, grammar) and somehow my memory goes up and stays up. Here is the function: from string import join from heapq import nsmallest, heappush def translate(f, g): words = f.split() chart = {} for col in range(len(words)): for row in reversed(range(0,col+1)): # get rules for this subspan rules = g[join(words[row:col+1], ' ')] # ensure there's at least one rule on the diagonal if not rules and row==col: rules=[(0.0, join(words[row:col+1]))] # pick up rules below & to the left for k in range(row,col): if (row,k) and (k+1,col) in chart: for (w1, e1) in chart[row, k]: for (w2, e2) in chart[k+1,col]: heappush(rules, (w1+w2, e1+' '+e2)) # add all rules to chart chart[row,col] = nsmallest(MAX_TRANSLATIONS, rules) (w, best) = chart[0, len(words)-1][0] return best EDIT: Using Python 2.7 on OS X. The grammar g is just a dictionary from strings to heaps, e.g.: g['et'] [(1.05, 'and'), (6.92, ', and'), (9.95, 'and ,'), (11.17, 'and to')] EDIT: If you want to run the code, try the sentence "Cela est difficile" with the following grammar: >>> g['cela'] [(8.28, 'this'), (11.21, 'it'), (11.57, 'that'), (15.26, 'this ,')] >>> g['est'] [(2.69, 'is'), (10.21, 'is ,'), (11.15, 'has'), (11.28, ', is')] >>> g['difficile'] [(2.01, 'difficult'), (10.08, 'hard'), (10.19, 'difficult ,'), (10.57, 'a difficult')]

  - by Kau-Boy

  I tried to switch from Java 5 to Java 6 using the "update-java-alternatives" command like explained on this page: https://help.ubuntu.com/community/Java But afterwards I get the following error when I tried to execute java: root@webserver:~# java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I also tried to reinstall the java binaries using "apt-get" but I didn't succeed reinstalling it. I would like to post the "apt-get" errors, but unfortunately I don't know how to print out the error messages in English and not in German. My system is a Ubuntu 8.04 ROOT server. Here is the (Google translated) english text tring to install Java 6 again: root@server:~# apt-get install sun-java6-jdk Reading package lists ... Ready Dependency tree Reading state information ... Ready sun-java6-jdk is already the newest version. sun-java6-jdk set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 86 not upgraded. 1 not fully installed or removed. After this operation, 0B of additional disk space will be used. Set up a sun-java6-bin (6-03-0ubuntu2) ...

• jQuery: Problems cookies internet explorer

  - by user1140479

  I have made a login page. When the user logs in a request to an API is send. This API is PHP and checks the username and password. When both are correct an unique key is send back (this is placed in the database for further use: userid and other stuff needed in the website). After that key is sent back it is placed in a cookie: $.cookie("session", JSON.stringify(result)); After the cookie is set I send the user to a new page: location.href = 'dashboard.htm'; In this page jQuery checks if the cookie "session" is present. If not, the user is send back to the login page. sessionId = ($.cookie("session") ? JSON.parse($.cookie("session")).SessionId : 0); return sessionId; This works fine in Chrome, but IE (8/9) has some problems with this. I figured out that when you get to dashboard.htm the session is present. As soon as I hit F5 the session is gone. And sometimes the cookie isn't set at all! I can't seem to figure out why this is happening in IE. Has someone any idea? Other options/ideas to save that unique key are also welcome. Thanks in advance.

• Trying to move files with specific file names from root directory to a subfolder

  - by Justin Reagan

  Hi I'm still pretty new to powershell so I apologize if I ask something that extremely basic. I have a root directory on a tftp server that pulls down config files from routers and other equipment every night. The files are like this IPaddress_YYYYMMDD_TA5000. There is a limitation in the equipment where the files can't be set to move into the root directory on their own. What I want to do is make a powershell script that will only move the files with the TA5000 part in the filename to the sub directory and only keep the 5 most recent files. I looked but I couldn't seem to find what I would need to do to parse the file for that specific string. I already have the portion of the script to delete the files based on age that was simple. Any help on getting started would be appreciated. Edit: I forgot to post the code I was trying. Move-Item c:\tftptransferfiles c:\tftptransferfiles\sca | Where-Object {_.name -like "*TA5000*"} I keep getting a error saying that the item at C:\tftptransferfiles is in use.
