• Programmatically added SummaryLinkWebPart doesn't display Links

  - by Mac

  Hi All, I am using below code to Add SummaryLinkWebPart to a Page and also adding few links to that wehbpart. I can see the webpart now on the page but it doesn't have any links inside it. Does anyone know what is wrong with the code? SPLimitedWebPartManager wpm = web.GetLimitedWebPartManager("Pages/default.aspx",PersonalizationScope.Shared); SummaryLinkWebPart slwp = new SummaryLinkWebPart(); for (int counter = 0; counter < list.ItemCount; counter++) { urlField = list.Items[counter]["URL"].ToString().Split(','); SummaryLink link = new SummaryLink(urlField[1].Trim()); slwp.SummaryLinkValue.SummaryLinks.Add(link); slwp.SummaryLinkValue.SummaryLinks[counter].OpenInNewWindow = true; slwp.SummaryLinkValue.SummaryLinks[counter].LinkUrl = urlField[0].Trim(); slwp.SummaryLinkValue.SummaryLinks[counter].Description = urlField[1]; slwp.Style = "Image on left"; Console.WriteLine(link.LinkUrl + link.Title); } wpm.AddWebPart(slwp, lvwp.ZoneID, slwp.ZoneIndex + 1);

• XCode can't find headers in /usr/include

  - by mindthief

  Hi all, I'm trying to use standard system header files in my C++ XCode project: #include <openssl/bio.h> #include <openssl/ssl.h> #include <openssl/err.h> The build fails and it complains: "Openssl/bio.h: No such file or directory" I added /usr/include to the "Header Search Paths" in Project settings, but that doesn't fix it. I COULD fix it by adding the whole path like: #include </usr/include/openssl/bio.h> -- but the project is full of similar includes and I don't want to change all of them this way. Also, I feel I shouldn't have to do this. Another way to fix it would be as another thread mentioned, which is to add /usr/include to User Header Search Paths. But if I do that, then I'd have to change all the angle brackets < to quotes "", which again seems like a hack. I mean, these are standard system header files so I feel it should be something simple, not requiring these kinds of hacks. Any ideas? Thanks!

• Best and simple way to handle JSON in Django

  - by primal

  Hi, As part of the application we are developing (with android client and Django server) a json object which contains user name and pass word is sent to server from android client as follows HttpPost post = new HttpPost(URL); /*Adding key value pairs */ json.put("username", un); json.put("password", pwd); StringEntity se = new StringEntity(json.toString()); post.setEntity(se); response = client.execute(post); The response is parsed like this result = responsetoString(response.getEntity().getContent()); //Converts response to String jObject = new JSONObject(result); JSONObject post = jObject.getJSONObject("post"); username = post.getString("username"); message = post.getString("message"); Hope upto this everything is fine. The problem comes when parsing or sending JSON responses in Django server. Whats the best way to do this? We tried using SimpleJSON and it turned out not to be so simple as we didn't find any good tutorials or sample code for the same? Are there any python functions similiar to get,put and opt in java for JSON? Any help would be much appreciated..

• Dependency Properties, change notification and setting values in the constructor

  - by stefan.at.wpf

  Hello, I have a clas with 3 dependency properties A,B,C. The values of these properties are set by the constructor and every time one of the properties A, B or C changes, the method recalculate() is called. Now during execution of the constructor these method is called 3 times, because the 3 properties A, B, C are changed. Hoewever this isn't necessary as the method recalculate() can't do anything really useful without all 3 properties set. So what's the best way for property change notification but circumventing this change notification in the constructor? I thought about adding the property changed notification in the constructor, but then each object of the DPChangeSample class would always add more and more change notifications. Thanks for any hint! class DPChangeSample : DependencyObject { public static DependencyProperty AProperty = DependencyProperty.Register("A", typeof(int), typeof(DPChangeSample), new PropertyMetadata(propertyChanged)); public static DependencyProperty BProperty = DependencyProperty.Register("B", typeof(int), typeof(DPChangeSample), new PropertyMetadata(propertyChanged)); public static DependencyProperty CProperty = DependencyProperty.Register("C", typeof(int), typeof(DPChangeSample), new PropertyMetadata(propertyChanged)); private static void propertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { ((DPChangeSample)d).recalculate(); } private void recalculate() { // Using A, B, C do some cpu intensive caluclations } public DPChangeSample(int a, int b, int c) { SetValue(AProperty, a); SetValue(BProperty, b); SetValue(CProperty, c); } }

• Python: How can I use Twisted as the transport for SUDS?

  - by jathanism

  I have a project that is based on Twisted used to communicate with network devices and I am adding support for a new vendor (Citrix NetScaler) whose API is SOAP. Unfortunately the support for SOAP in Twisted still relies on SOAPpy, which is badly out of date. In fact as of this question (I just checked), twisted.web.soap itself hasn't even been updated in 21 months! I would like to ask if anyone has any experience they would be willing to share with utilizing Twisted's superb asynchronous transport functionality with SUDS. It seems like plugging in a custom Twisted transport would be a natural fit in SUDS' Client.options.transport, I'm just having a hard time wrapping my head around it. I did come up with a way to call the SOAP method with SUDS asynchronously by utilizing twisted.internet.threads.deferToThread(), but this feels like a hack to me. Here is an example of what I've done, to give you an idea: # netscaler is a module I wrote using suds to interface with NetScaler SOAP # Source: http://bitbucket.org/jathanism/netscaler-api/src import netscaler import os import sys from twisted.internet import reactor, defer, threads # netscaler.API is the class that sets up the suds.client.Client object host = 'netscaler.local' username = password = 'nsroot' wsdl_url = 'file://' + os.path.join(os.getcwd(), 'NSUserAdmin.wsdl') api = netscaler.API(host, username=username, password=password, wsdl_url=wsdl_url) results = [] errors = [] def handleResult(result): print '\tgot result: %s' % (result,) results.append(result) def handleError(err): sys.stderr.write('\tgot failure: %s' % (err,)) errors.append(err) # this converts the api.login() call to a Twisted thread. # api.login() should return True and is is equivalent to: # api.service.login(username=self.username, password=self.password) deferred = threads.deferToThread(api.login) deferred.addCallbacks(handleResult, handleError) reactor.run() This works as expected and defers return of the api.login() call until it is complete, instead of blocking. But as I said, it doesn't feel right. Thanks in advance for any help, guidance, feedback, criticism, insults, or total solutions.

• Using Doctrine to abstract CRUD operations

  - by TomWilsonFL

  This has bothered me for quite a while, but now it is necessity that I find the answer. We are working on quite a large project using CodeIgniter plus Doctrine. Our application has a front end and also an admin area for the company to check/change/delete data. When we designed the front end, we simply consumed most of the Doctrine code right in the controller: //In semi-pseudocode function register() { $data = get_post_data(); if (count($data) && isValid($data)) { $U = new User(); $U->fromArray($data); $U->save(); $C = new Customer(); $C->fromArray($data); $C->user_id = $U->id; $C->save(); redirect_to_next_step(); } } Obviously when we went to do the admin views code duplication began and considering we were in a "get it DONE" mode so it now stinks with code bloat. I have moved a lot of functionality (business logic) into the model using model methods, but the basic CRUD does not fit there. I was going to attempt to place the CRUD into static methods, i.e. Customer::save($array) [would perform both insert and update depending on if prikey is present in array], Customer::delete($id), Customer::getObj($id = false) [if false, get all data]. This is going to become painful though for 32 model objects (and growing). Also, at times models need to interact (as the interaction above between user data and customer data), which can't be done in a static method without breaking encapsulation. I envision adding another layer to this (exposing web services), so knowing there are going to be 3 "controllers" at some point I need to encapsulate this CRUD somewhere (obviously), but are static methods the way to go, or is there another road? Your input is much appreciated.

• Dynamic ExpandableListView

  - by JLB

  Can anyone tell me how I can Dynamically add groups & children to an ExpandableListView. The purpose is to create a type of task list that I can add new items/groups to. I can populate the view with pre-filled arrays but of course can't add to them to populate the list further. The other method i tried was using the SimpleExpandableListAdapter. Using this i am able to add groups from a List but when it comes to adding children i can only add 1 item per group. public List<Map<String, String>> groupData = new ArrayList<Map<String, String>>(); public List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>(); public void addGroup(String group) { Map curGroupMap = new HashMap(); groupData.add(curGroupMap); curGroupMap.put(NAME, group); //Add an empty child or else the app will crash when group is expanded. List<Map<String, String>> children = new ArrayList<Map<String, String>>(); Map<String, String> curChildMap = new HashMap<String, String>(); children.add(curChildMap); curChildMap.put(NAME, "EMPTY"); childData.add(children); updateAdapter(); } public void addChild(String child) { List children = new ArrayList(); Map curChildMap = new HashMap(); children.add(curChildMap); curChildMap.put(NAME, child); curChildMap.put(IS_EVEN, "This child is even"); childData.add(activeGroup, children); updateAdapter(); }

• How to create databinding over two xaml files?

  - by BionicGecko

  Hello, I am trying to come to a working understanding of how databinding works, but even after several tutorials I only have a basic understanding of how databinding works. Thus this question might seem fundamental to those more familiar with silverlight. Even if it is trivial, please point me to some tutorial that deals with this problem. All that I could find simply solved this via adding the data binding on a parent page.xaml (that i must not use in my case). For the sake of this example let us assume, that we have 5 files: starter.cs button1.xaml + codeBehind button2.xaml + codeBehind The two buttons are generated in code in the starter(.cs) file, and then added to some MapLayer button1 my_button1 = new button1(); button2 my_button1 = new button2(); someLayer.Children.Add(my_button1); someLayer.Children.Add(my_button2); My aim is to connect the two buttons, so that they always display the same "text" (i.e. my_button1.content==my_button2.content = true;). Thus when something changes my_button1.content this change should be propagated to the other button (two way binding). At the moment my button1.xaml looks like this: <Grid x:Name="LayoutRoot"> <Button x:Name="x_button1" Margin="0,0,0,0" Content="{Binding ElementName=x_button2, Path=Content}" ClickMode="Press" Click="button1_Click"/> </Grid> But everthing that i get out of that is a button with no content at all, it is just blank as the binding silently fails. How could I create the databinding in the context I described? Preferably in code and not XAML ;) Thanks in advance

• How to find if a branch is a locally tracked branch or user created local branch?

  - by Senthil A Kumar

  I have a remote tracking branch tracked locally in my local repository using 'git branch -b branch-name origin/branch-name'. My remote branch is test2/test2 (origin/branch-name) which is being tracked locally as test2. The origin is also named test2. I haven't checked-out my local tracking branch test2. When i do a 'git pull origin remote-branch:local-tracked-branch' i get this error [test2]$ git pull test2 test2:test2 From /gitvobs/git_bare/test2 ! [rejected] test2 - test2 (non fast forward) Whereas when i checkout my local tracking branch test2 and do pull 'git pull origin local-tracked-branch' i don't get the error and i do a pull using 'git pull test2 test2' From /gitvobs/git_bare/test2 * branch test2 - FETCH_HEAD Auto-merging a.txt Automatic merge failed; fix conflicts and then commit the result. i know that adding a + (git pull test2 +test2:test2) would help but it overwrites local changes. So how do i know which of my local branches are created by me locally using 'git branch new-branch-name' or tracked locally from remote branches using git branch -b branch-name origin/branch-name'?

• asp.net mvc: What is the correct way to return html from controller to refresh select list?

  - by Mark Redman

  Hi, I am new to ASP.NET MVC, particularly ajax operations. I have a form with a jquery dialog for adding items to a drop-down list. This posts to the controller action. If nothing (ie void method) is returned from the Controller Action the page returns having updated the database, but obviously there no chnage to the form. What would be the best practice in updating the drop down list with the added id/value and selecting the item. I think my options are: 1) Construct and return the html manually that makes up the new <select> tag [this would be easy enough and work, but seems like I am missing something] 2) Use some kind of "helper" to construct the new html [This seems to make sense] 3) Only return the id/value and add this to the list and select the item [This seems like an overkill considering the item needs to be placed in the correct order etc] 4) Use some kind of Partial View [Does this mean creating additional forms within ascx controls? not sure how this would effect submitting the main form its on? Also unless this is reusable by passing in parameters(not sure how thats done) maybe 2 is the option?] UPDATE: Having looked around a bit, it seems that generating html withing the controller is not a good idea. I have seen other posts that render partialviews to strings which I guess is what I need and separates concerns (since the html bits are in the ascx). Any comments on whether that is good practice.

• Visual Studio 2010 Professional - Problem Unit-Testing Web Services

  - by Ben

  Have created a very simple Web Service (asmx) in Visual Studio 2010 Professional, and am trying to use the auto-generated unit test cases. I get something that seems quite familiar on this site: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:81/zfp/VSEnterpriseHelper.axd return an error: The remote server returned an error: (500) Internal Server Error. http://stackoverflow.com/questions/260432/500-error-running-visual-studio-asp-net-unit-test I have tried: 1. Running the tests on IIS rather than ASP.NET Development Server 2. Adding and then removing the XML fragment to my Web Service's .config file 3. Giving the MACHINE\ASPNET account Full control to the local folder My current questions: 1. Why am I being bothered with this instrumentation / code coverage DLL, when this doesn't seem to be something that ships with Visual Studio 2010 Professional? Is there any way I can turn it off? 2. I'm placing the node under in Web.config - is that the correct node? 3. Is it possible to bind to a web service without using the webby test attributes? I've seen other people advising making the Web Service as light-weight as possible. I'm trying to call it with jQuery / AJAX / JSON, so being able to debug the actual web service would be really helpful. Best wishes, Ben

• bad_alloc occuring when allocating small structs

  - by SalamiArmi

  A bad_alloc has started showing up in some code which looks perfectly valid to me and has worked very well in the past. The bad alloc only occurs once every 50-3000 iterations of the code, which is also confusing. The code itself is from a singly linked list, simply adding a new element to the queue: template<typename T> struct container { inline container() : next(0) {} container *next; T data; }; void push(const T &data) { container<T> *newQueueMember = new container<T>; //... unrelated to crash } Where T is: struct test { int m[256]; }; Changing the size of the array allocated array to anything but very small values (1-8 ints) still results in a bad_alloc occasionally. A few extra notes about my program: - I used Poco::ThreadPool to thread my program. I've only recently added this functionality, before I had it running with Win32 threads. However, only the main thread ever calls push(). - I am also occasionally getting other crashes which could be related. However, when I try to debug with visual studio 2008, I can't navigate back to the call stack, or the crash happens deep within new(). Thanks in advance.

• The Classic jQuery Tabs with Bing Maps Issue

  - by Justin

  Hello, I know that there are multiple issues with jQuery Tabs and using Maps. And I have seen the multiple fixes and I am half-way there. But I have the most obscure issue and hoping that someone might understand why. This is my code for the tabs $("#contactTabs").tabs({ spinner: 'Loading <img src="../images/icons/ajax-loader.gif" />' }); $('#contactTabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "Map") { GetMap(); } }); Which currently does not work. But I was doing some testing and added in an ALERT() to see if the "GetMap()" was even attempting to be loaded... so this was the code that I tested with, and it works just fine. $("#contactTabs").tabs({ spinner: 'Loading <img src="../images/icons/ajax-loader.gif" />' }); $('#contactTabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "Map") { alert("load map"); GetMap(); } }); So I haven't a clue why adding the ALERT() causes the map to load and removing the ALERT just doesn't load the map at all. Is there any clarification that someone can give me on this issue? Thank you in advance!

• AdvancedDataGrid dynamic text Value Coloring - ItemRenderer problem

  - by sri

  In my AdvancedDataGrid, I am adding dynamic values to cells by dragging a cell value to other cells. While copying, I am setting the value to listData and setting the Red color to the value in ItemRenderer. Everything is working fine, but when I scroll down/up, the values remains in the cells where thay are supposed to be(as I am setting to listData) but the coloring behaves wierd(as I am trying to set the color in ItemRenderer). I don't want to store the color of the value, but I should be able to see the dynamically created values in Red color. Is there a way, I can do this? Do I need to set the color to actual dataprovider object and then check in ItemRenderer? Can anyone help me with this? public class CustomItemRenderer extends AdvancedDataGridItemRenderer { private var _isDynamicValue:Boolean; .... .... //_isDynamicValue is set to true if the value is dynamic if(_isDynamicValue && listData.label) { setStyle("color", 0xFF0000); setStyle("fontWeight", "bold"); } else { setStyle("color", 0x000000); }

• Making text align equally in both IE and Chrome

  - by bobo

  <style type="text/css"> h2{ font-size:13px; line-height:16px; color:#000000; margin:0; padding:6px 22px; font-family: 'Times New Roman'; } div{ border:1px solid black; } </style> <div> <h2> ????????</h2> </div> Pasting the above codes here: http://htmledit.squarefree.com/ You will see that the text stays a little bit higher in the div in IE than in Chrome, I would like to make them consistent. By adding a &nbsp; after the text within the <h2>in IE, the text will automatically move up, which is consistent with Chrome. But I don't quite like this hack, so I would like to know if anybody knows what problem this is and recommends a better way to fix it if possible. Many thanks to you all. Note: this problem does not appear if the text is english only.

• How to reuse results with a schema for end of day stock-data

  - by Vishalrix

  I am creating a database schema to be used for technical analysis like top-volume gainers, top-price gainers etc.I have checked answers to questions here, like the design question. Having taken the hint from boe100 's answer there I have a schema modeled pretty much on it, thusly: Symbol - char 6 //primary Date - date //primary Open - decimal 18, 4 High - decimal 18, 4 Low - decimal 18, 4 Close - decimal 18, 4 Volume - int Right now this table containing End Of Day( EOD) data will be about 3 million rows for 3 years. Later when I get/need more data it could be 20 million rows. The front end will be asking requests like "give me the top price gainers on date X over Y days". That request is one of the simpler ones, and as such is not too costly, time wise, I assume. But a request like " give me top volume gainers for the last 10 days, with the previous 100 days acting as baseline", could prove 10-100 times costlier. The result of such a request would be a float which signifies how many times the volume as grown etc. One option I have is adding a column for each such result. And if the user asks for volume gain in 10 days over 20 days, that would require another table. The total such tables could easily cross 100, specially if I start using other results as tables, like MACD-10, MACD-100. each of which will require its own column. Is this a feasible solution? Another option being that I keep the result in cached html files and present them to the user. I dont have much experience in web-development, so to me it looks messy; but I could be wrong ( ofc!) . Is that a option too? Let me add that I am/will be using mod_perl to present the response to the user. With much of the work on mysql database being done using perl. I would like to have a response time of 1-2 seconds.

• Wireshark Dissector: How to Identify Missing UDP Frames?

  - by John Dibling

  How do you identify missing UDP frames in a custom Wireshark dissector? I have written a custom dissector for the CQS feed (reference page). One of our servers gaps when receiving this feed. According to Wireshark, some UDP frames are never received. I know that the frames were sent because all of our other servers are gap-free. A CQS frame consists of multiple messages, each having its own sequence number. My custom dissector provides the following data to Wireshark: cqs.frame_gaps - the number of gaps within a UDP frame (always zero) cqs.frame_first_seq - the first sequence number in a UDP frame cqs.frame_expected_seq - the first sequence number expected in the next UDP frame cqs.frame_msg_count - the number of messages in this UDP frame And I am displaying each of these values in custom columns, as shown in this screenshot: I tried adding code to my dissector that simply saves the last-processed sequence number (as a local static), and flags gaps when the dissector processes a frame where current_sequence != (previous_sequence + 1). This did not work because the dissector can be called in random-access order, depending on where you click in the GUI. So you could process frame 10, then frame 15, then frame 11, etc. Is there any way for my dissector to know if the frame that came before it (or the frame that follows) is missing? The dissector is written in C. (See also a companion post on serverfault.com)

• Slow Python HTTP server on localhost

  - by Abiel

  I am experiencing some performance problems when creating a very simple Python HTTP server. The key issue is that performance is varying depending on which client I use to access it, where the server and all clients are being run on the local machine. For instance, a GET request issued from a Python script (urllib2.urlopen('http://localhost/').read()) takes just over a second to complete, which seems slow considering that the server is under no load. Running the GET request from Excel using MSXML2.ServerXMLHTTP also feels slow. However, requesting the data Google Chrome or from RCurl, the curl add-in for R, yields an essentially instantaneous response, which is what I would expect. Adding further to my confusion is that I do not experience any performance problems for any client when I am on my computer at work (the performance problems are on my home computer). Both systems run Python 2.6, although the work computer runs Windows XP instead of 7. Below is my very simple server example, which simply returns 'Hello world' for any get request. from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer class MyHandler(BaseHTTPRequestHandler): def do_GET(self): print("Just received a GET request") self.send_response(200) self.send_header("Content-type", "text/html") self.end_headers() self.wfile.write('Hello world') return def log_request(self, code=None, size=None): print('Request') def log_message(self, format, *args): print('Message') if __name__ == "__main__": try: server = HTTPServer(('localhost', 80), MyHandler) print('Started http server') server.serve_forever() except KeyboardInterrupt: print('^C received, shutting down server') server.socket.close() Note that in MyHandler I override the log_request() and log_message() functions. The reason is that I read that a fully-qualified domain name lookup performed by one of these functions might be a reason for a slow server. Unfortunately setting them to just print a static message did not solve my problem. Also, notice that I have put in a print() statement as the first line of the do_GET() routine in MyHandler. The slowness occurs prior to this message being printed, meaning that none of the stuff that comes after it is causing a delay.

• Where to post code for open source usage?

  - by Douglas

  I've been working for a few weeks now with the Google Maps API v3, and have done a good bit of development for the map I've been creating. Some of the things I've done have had to be done to add usability where there previously was not any, at least not that I could find online. Essentially, I made a list of what had to be done, searched all over the web for the ways to do what I needed, and found that some were not(at the time) possible(in the "grab an example off the web" sense). Thus, in my working on this map, I have created a number of very useful tools, which I would like to share with the development community. Is there anywhere I could use as a hub, apart from my portfolio ( http://dougglover.com ), to allow people to view and recycle my work? I know how hard it can be to need to do something, and be unable to find the solution elsewhere, and I don't think that if something has been done before, it should necessarily need to be written again and again. Hence open source code, right? Firstly, I was considering coming on here and asking a question, and then just answering it. Problem there is I assume that would just look like a big reputation grab. If not, please let me know and I'll go ahead and do that so people here can see it. Other suggestions appreciated. Some stuff I've made: A (new and improved) LatLng generator Works quicker, generates LatLng based on position of a draggable marker Allows searching for an address to place the marker on/near the desired location(much better than having to scroll to your location all the way from Siberia) Since it's a draggable marker, double-clicking zooms in, instead of creating a new LatLng marker like the one I was originally using The ability to create entirely custom "Smart Paths" Plot LatLng points on the map which connect to each other just like they do using the actual Google Maps Using Dijkstra's algorithm with Javascript, the routing is intelligent and always gives the shortest possible route, using the points provided Simple, easy to read multi-dimensional array system allows for easily adding new points to the grid Any suggestions, etc. appreciated.

• Alpha animation bug on button

  - by RaiderJ

  I have animations that fade in a Button (alpha from 0 to 1) and fade out a button (alpha from 1 to 0). This part is all working fine. Button A triggers the fade in of Button B. Button B triggers the fade out of itself. Button B totally covers up Button A. The idea is that Button B contains an image that is used like an information popup. Button A is touched and Button B fades in on top. When Button B is touched it fades itself out again. Initially, Button B's visibility is set INVISIBLE and when the fade in animation is complete, it is set to VISIBLE. When Button B is clicked it fades out and then I set the visibility to INVISIBLE. The problem is that after Button B has faded out, and it is set INVISIBLE, it is still clickable and even though it is not visible, and touches are not received by Button A. I have tried removing Button B from the parent and re-adding it after the animation is completed, and this allows for touches to reach Button A, but only once. After that button B is not longer touchable.

• C# DynamicMethod prelink

  - by soywiz

  I'm the author of a psp emulator made in C#. I'm generating lots of "DynamicMethod" using ILGenerator. I'm converting assembly code into an AST, and then generating IL code and building that DynamicMethod. I'm doing this in another thread, so I can generate new methods while the program is executing others so it can run smoothly. My problem is that the native code generation is lazy, so the machine code is generated when the function is called, not when the IL is generated. So it generates in the program executing thread, native code generation is prettly slow as it is the asm-ast-il step. I have tried the Marshal.Prelink method that it is suposed to generate the machine code before executing the function. It does work on Mono, but it doesn't work on MS .NET. Marshal.Prelink(MethodInfo); Is there a way of prelinking a DynamicMethod on MS .NET? I thought adding a boolean parameter to the function that if set, exits the function immediately so no code is actually executed. I could "prelink" that way, but I think that's a nasty solution I want to avoid. Any idea?

I create a view over that table adding one column which is just that date plus 20 minutes: #!/usr/bin/env ruby %w|pp rubygems active_record irb active_support date|.each {|lib| require lib} ActiveRecord::Base.establish_connection( :adapter => "sqlite3", :database => "test.db" ) ActiveRecord::Schema.define do create_table :people, :force => true do |t| t.column :name, :string t.column :born_at, :datetime end execute "create view clowns as select p.name, p.born_at, datetime(p.born_at, '+' || '20' || ' minutes') as twenty_after_born_at from people p;" end class Person < ActiveRecord::Base validates_presence_of :name end class Clown < ActiveRecord::Base end Person.create(:name => "John", :born_at => DateTime.now) pp Person.all.first.born_at.class pp Clown.all.first.born_at.class pp Clown.all.first.twenty_after_born_at.class The problem is, the output is Time Time String When I expect the new datetime attribute of the view to be also a Time or DateTime in the ruby world. Any ideas? I also tried: create view clowns as select p.name, p.born_at, CAST(datetime(p.born_at, '+' || '20' || ' minutes') as datetime) as twenty_after_born_at from people p; With the same result.

• RPC for java/python with rest support, HTML monitoring and goodies

  - by Ran

  Here's my set of requirements: I'm looking for an RPC framework such as thrift, avro, protobuf (when adding services to it) which supports: Easy and intuitive IDL. No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks

• UTF8 charset, diacritical elements, conversion problems - and Zend Framework form escaping

  - by imanc

  Hey, I am writing a webapp in ZF and am having serious issues with UTF8. It's using multi lingual content through Zend Form and it seems that ZF heavily escapes all of these characters and basically just won't show a field if there's diacritical elements 'é' and if I use the HTML entity equivalent e.g. é it gets escaped so that the user will see 'é'. Zend Form allows for having non escaped data, but trying to use this is confusing, and it seems it'd need to be used all over the place. So, I have been told that if the page and the text is in UTF8, no conversion to htmlentities is required. Is this true? And if the last question is true, then how do I convert the source text to UTF8? I am comfortable setting up apache so that it sends a default UTF8 charset heading, and also adding the charset meta tag to the html, but doing this I am still getting messed up encoding. I have also tried opening the translation csv file in TextWrangler on OSX as UTF8, but it has done nothing. Thanks! L

• Saving Abstract and Sub classes to database

  - by bretddog

  Hi, I have an abstract class "StrategyBase", and a set of sub classes, StrategyA/B/C etc. The sub classes use some of the properties of the base class, and have some individual properties. My question is how to save this to a database. I'm currently using SqlCE, and Linq-To-Sql by creating entity classes automatically with SqlMetal.exe. I've seen there are three solutions shown in this question, but I'm not able to see how these solutions will work or not with SqlMetal/entity classes. Though it seems to me the "concrete table inheritance" would probably work without any manual modifying. What about the other two, would they be problematic? For "Single Table Inheritance" wouldn't all classes get all variables, even though they don't need them? And for the "Class table inheritance" solution I can't really see at all how that will map into the entity-classes for a useful purpose. I may note that I extend these partial entity classes for making the classes of my business objects. I may also consider moving to EntityFramework instead of SqlMetal/Linq2Sql, so would be nice also to know if that makes any difference to what schema is easy to implement. One likely important thing to note is that I will constantly be develop new strategies, which makes me have to modify the program code, and probably the database shcema; when adding a new strategy. Sorry the question is a bit "all over the place", but hopefully it's some clear advantages/disadvantages here that you may be able to advice. ? Cheers!
