• GridView's NewValues and OldValues empty in the OnRowUpdating event.

  - by Abe Miessler

  I have the GridView below. I am binding to a custom datasource in the code behind. It gets into the "OnRowUpdating" event just fine, but there are no NewValues or OldValues. Any suggestions as to how I can get these values? <asp:GridView ID="gv_Personnel" runat="server" OnRowDataBound="gv_Personnel_DataBind" OnRowCancelingEdit="gv_Personnel_CancelEdit" OnRowEditing="gv_Personnel_EditRow" OnRowUpdating="gv_Personnel_UpdateRow" AutoGenerateColumns="false" ShowFooter="true" DataKeyNames="BudgetLineID" AutoGenerateEditButton="true" AutoGenerateDeleteButton="true" > <Columns> <asp:BoundField HeaderText="Level of Staff" DataField="LineDescription" /> <%--<asp:BoundField HeaderText="Hrs/Units requested" DataField="NumberOfUnits" />--%> <asp:TemplateField HeaderText="Hrs/Units requested"> <ItemTemplate> <%# Eval("NumberOfUnits")%> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="tb_NumUnits" runat="server" Text='<%# Bind("NumberOfUnits")%>' /> </EditItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="Hrs/Units of Applicant Cost Share" DataField="" NullDisplayText="0" /> <asp:BoundField HeaderText="Hrs/Units of Partner Cost Share" DataField="" NullDisplayText="0" /> <asp:BoundField FooterStyle-Font-Bold="true" FooterText="TOTAL PERSONNEL SERVICES:" HeaderText="Rate" DataFormatString="{0:C}" DataField="UnitPrice" /> <asp:TemplateField HeaderText="Amount Requested" ItemStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" FooterStyle-BorderWidth="2" FooterStyle-Font-Bold="true"/> <asp:TemplateField HeaderText="Applicant Cost Share" ItemStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" FooterStyle-BorderWidth="2" FooterStyle-Font-Bold="true"/> <asp:TemplateField HeaderText="Partner Cost Share" ItemStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" FooterStyle-BorderWidth="2" FooterStyle-Font-Bold="true"/> <asp:TemplateField HeaderText="Total Projet Cost" ItemStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" FooterStyle-BorderWidth="2" FooterStyle-Font-Bold="true"/> </Columns> </asp:GridView>

• Why does presentModalViewController not always work?

  - by E-Madd

  My application requires data from a server in order to run. The first thing it does is displays a view controller (LoadingViewController) that is responsible for checking if the data is saved to my PersistentStoreCoordinator. If the data isn't cached locally, it gets it from my server and caches it, and posts a notification that the LoadingViewController is listening for. When that notification comes through, LoadingViewController presents the application's MainViewController using the presentModalViewController with a flip animation. So far, so good... no errors. However, if the application loads and determines the data IS cached - the presentModalViewController does not work and the main application view never appears. No errors. I've even gone as far as adding a button to the Loading view that executes the same code when pressed and the damn thing works. I'm suspicious it has something to do with the timing of it all but I'm clueless as to what I can do to ensure the view is displayed with that flipping animation if the data is already cached locally. Any suggestions?

• Is there the equivalent of cloud computing for modems?

  - by morpheous

  I asked this question on SF, and someone recommended that I ask it here - (I don't think I have enough points to move a question from SF to SO - and in any case, I don't know how to do it - so here is the question again): I am interested in the concept of PAAS (platform as a service). However, all talk about SAAS/PAAS seems to focus on only the computer itself - not its peripherals. Is it possible to 'outsource' modems as a resource - so that an app running remotely can pump data to a modem in the cloud? As a bit of background to the question, a group of us are thinking of starting a company that offers similar services to companies like twilio etc - but I want to 'outsource' both the computing hardware (thats PAAS - the easy bit) and the modems (thats what I cant seem to find any info on). Does anyone know if modems can be bundled as part of a PAAS service? - alternatively, is there a way that an application running on one computer can communicate (i.e. pump data) to a remote modem residing on another machine?. I assume I can come up with some protocol over UDP or TCP - but there is no point reinventing the wheel - if such a protocol like that already exists (or if it some open source software allows one to do this). Any suggestions on how to solve this problem?

• Commit is VERY slow in my NHibernate / SQLite project

  - by Tom Bushell

  I've just started doing some real-world performance testing on my Fluent NHibernate / SQLite project, and am experiencing some serious delays when when I Commit to the database. By serious, I mean taking 20 - 30 seconds to Commit 30 K of data! This delay seems to get worse as the database grows. When the SQLite DB file is empty, commits happen almost instantly, but when it grows to 10 Meg, I see these huge delays. The database has 16 tables, averaging 10 columns each. One possible problem is that I'm storing a dozen or so IList members, but they are typically only 200 elements long. But this is a recent addition to Fluent NHibernate automapping, which stores each float in a single table row, so maybe that's a potential problem. Any suggestions on how to track this down? I suspect SQLite is the culprit, but maybe it's NHibernate? I don't have any experience with profilers, but am thinking of getting one. I'm aware of NHibernate Profiler - any recommendations for profilers that work well with SQLite? Here's the method that saves the data - it's just a SaveOrUpdate call and a Commit, if you ignore all the error handling and debug logging. public static void SaveMeasurement(object measurement) { Debug.WriteLine("\r\n---SaveMeasurement---"); // Get the application's database session var session = GetSession(); using (var transaction = session.BeginTransaction()) { try { session.SaveOrUpdate(measurement); } catch (Exception e) { throw new ApplicationException( "\r\n SaveMeasurement->SaveOrUpdate failed\r\n\r\n", e); } try { Debug.WriteLine("\r\n---Commit---"); transaction.Commit(); Debug.WriteLine("\r\n---Commit Complete---"); } catch (Exception e) { throw new ApplicationException( "\r\n SaveMeasurement->Commit failed\r\n\r\n", e); } } }

• Variable Assignment and loops (Java)

  - by Raven Dreamer

  Greetings Stack Overflowers, A while back, I was working on a program that hashed values into a hashtable (I don't remember the specifics, and the specifics themselves are irrelevant to the question at hand). Anyway, I had the following code as part of a "recordInput" method. tempElement = new hashElement(someInt); while(in.hasNext() == true) { int firstVal = in.nextInt(); if (firstVal == -911) { break; } tempElement.setKeyValue(firstVal, 0); for(int i = 1; i<numKeyValues;i++) { tempElement.setKeyValue(in.nextInt(), i); } elementArray[placeValue] = tempElement; placeValue++; } // close while loop } // close method This part of the code was giving me a very nasty bug -- no matter how I finagled it, no matter what input I gave the program, it would always produce an array full of only a single value -- the last one. The problem, as I later determined it, was that because I had not created the tempElement variable within the loop, and because values were not being assigned to elementArray[] until after the loop had ended -- every term was defined rather as "tempElement" -- when the loop terminated, every slot in the array was filled with the last value tempElement had taken. I was able to fix this bug by moving the declaration of tempElement within the while loop. My question to you, Stackoverflow, is whether there is another (read: better) way to avoid this bug while keeping the variable declaration of tempElement outside the while loop. (suggestions for better title and tags also appreciated)

• Test-First development tool for SQL Server 2005?

  - by Jeff Jones

  For several years I have been using a testing tool called qmTest that allows me to do test-driven database development for some Firebird databases. I write a test for a new feature (table, trigger, stored procedure, etc.) until it fails, then modify the database until the test passes. If necessary, I do more work on the test until it fails again, then modify the database until the test passes. Once the test for the feature is complete and passes 100% of the time, I save it in a suite of other tests for the database. Before moving on to another test or a deployment, I run all the tests as a suite to make sure nothing is broken. Tests can have dependencies on other tests, and the results are recorded and displayed in a browser. Nothing new here, I am sure. Our shop is aiming toward standardizing on MSSQLServer and I want to use the same procedure for developing our databases. Does anyone know of tools that allow or encourage this kind of development? I believe the Team System does, but we do not own that at this point, and probably will not for some time. I am not opposed to scripting, but would welcome a more graphical environment. Any suggestions?

• Serializing a part of object graph

  - by Felix

  Hi all, I have a problem regarding Java custom serialization. I have a graph of objects and want to configure where to stop when I serialize a root object from client to server. Let's make it a bit concrete, clear by giving a sample scenario. I have Classes of type Company Employee (abstract) Manager extends Employee Secretary extends Employee Analyst extends Employee Project Here are the relations: Company(1)---(n)Employee Manager(1)---(n)Project Analyst(1)---(n)Project Imagine, I'm on the client side and I want to create a new company, assign it 10 employees (new or some existing) and send this new company to the server. What I expect in this scenario is to serialize the company and all bounding employees to the server side, because I'll save the relations on the database. So far no problem, since the default Java serialization mechanism serializes the whole object graph, excluding the field which are static or transient. My goal is about the following scenario. Imagine, I loaded a company and its 1000 employees from the server to the client side. Now I only want to rename the company's name (or some other field, that directly belongs to the company) and update this record. This time, I want to send only the company object to the server side and not the whole list of employees (I just update the name, the employees are in this use case irrelevant). My aim also includes the configurability of saying, transfer the company AND the employees but not the Project-Relations, you must stop there. Do you know any possibility of achieving this in a generic way, without implementing the writeObject, readObject for every single Entity-Object? What would be your suggestions? I would really appreciate your answers. I'm open to any ideas and am ready to answer your questions in case something is not clear.

• Multiple WCF calls for a single ASP.NET page load

  - by Rodney Burton

  I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing. Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL. Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode: public class ViewOrderPageDTO { public OrderDTO[] Orders { get; set; } public OrderTypesDTO[] OrderTypes { get; set; } public OrderStatusesDTO[] OrderStatuses { get; set; } public CustomerListDTO[] CustomerList { get; set; } } Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO? Thanks for your input and suggestions.

• Login for webapp, needs to be availible for supportstaff

  - by Christian W

  I know the title is a little off, but it's hard to explain the problem in a short sentence. I am the administrator of a legacy webapp that lets users create surveys and distribute them to a group of people. We have two kinds of "users". 1. Authorized licenseholders which does all setup themselves. 2. Clients who just want to have a survey run, but still need a user (because the webapp has "User" as the top entity in a surveyenvironment.) Sometimes users in #1 want's us to do the setup for them (which we offer to do). This means that we have to login as them. This is also how we do support, we login as them and then follow them along, guiding them. Which brings me to my dilemma. Currently our security is below par. But this makes it simple for us to do support. We do want to increase our security, and one thing I have been considering is just doing the normal hashing to DB, however, we need to be able to login as a customer, and if they change their password without telling us, and the password is hashed in the db, we have no way of knowing it. So I was thinking of some kind of twoway encryption for the passwords. Either that or some kind of master password. Any suggestions? (The platform is classic ASP... I said it was legacy...)

• Simple Java Applet not loading in FireFox / Safari on MacOS

  - by Sleepless

  Hello all, I'm probably missing something very basic here. I'm trying to get my first applet to run inside a local HTML page in Firefox 3.6 on Mac OS 10.5.8. Here's the applet's code: package SimpleApplet; import java.applet.Applet; import java.awt.*; public class MyApplet extends Applet { private static final long serialVersionUID = 1L; public void init() { } public void stop() { } public void paint(Graphics g) { g.drawString("Tweedle-Dee!",20,40); } } Here's the HTML page: <html> <body> Here's the applet: <br/> <applet code="MyApplet.class" width="300" height="150"> </applet> </body> </html> Both files (.class and .html) are in the same folder on my local machine. Now when I load the .html file into Firefox, a rectangle with a red X gets displayed. The applet works when started from Eclipse (using JRE 1.5 BTW). Also, it's not a general problem with my browser, as several pages with applets (e.g. http://java.sun.com/applets/jdk/1.4/demo/applets/Blink/example1.html) work. This is also difficult to troubleshoot because there is no output at all on the Java console... Any suggestions are appreciated!

• Inserting script from jQuery / Javascript

  - by Colby77

  Hi, I'm trying to insert reCaptcha code into my page from jQuery, but it doesn't work. Here is my code: $("#button").click(function() { $("#loginBox").html($.getRecaptcha()); }) When I try the following, my code doesn't even run. I think it's trying to execute instead of rendering it. $.getRecaptcha = function(){ return '<script type="text/javascript"' + 'src="http://api.recaptcha.net/challenge?' + 'k=6Ld3iAsAAAAAAGyX8QT244GagPEpCDSD-96o4gEi"></script>'; } With the following, the code runs, but when I click to #button I get an empty, full white browser window. $.getRecaptcha = function(){ var captcha = $("<script>") .attr("type", "text/javascript") .attr("src", "http://api.recaptcha.net/challenge?k=6Ld3iAsAAAAAAGyX8QT244GagPEpCDSD-96o4gEi"); return captcha; } I don't want to insert reCaptcha code into my html from the beginning, because it downloads the reCaptcha content from the reCaptcha server even if my users don't want to use it. I could set the visibility of the container that holds the reCaptcha to invisible (display: none;), but it will dowload the content irrespectively of it. I can insert the "noScript" code that reCaptcha gives us, but it doesn't work either, because it can spot that the browser allow javascript but I use noScript. Any suggestions? (I know I put my public reCaptcha key into the code, but it is just for testing purposes, and you could get it from my html or javascript code anyway)

• WIKI replacement solution for SharePoint?

  - by Jakub

  I'm trying to research a replacement for the pathetic WIKI that comes with WSS (only wiki code it has is to create url links). I have looked at a few but most 'replacements' I see are MOSS only? (or so it just states MOSS for requirements). Has anyone faced this situation? What did you end up using? I would like something that I can have all in one location (not different apps, hence WSS). With LDAP / AD Integration like WSS. Thanks appreciate any input. I would like to see ~ $3k solutions tho (nothing super expensive, hence why we don't run MOSS). EDIT: Anyone else have any suggestions? EDIT2: Actually since I haven't had much feedback (thanks to those that have). I installed mediawiki under IIS with PHP enabled, and enabled the IIS AD hack for authentication. IIS ends up prompting for authentication (user/pass) if you use a non IE browser, then it sets the $_SERVER["REMOTE_USER"] variable, and grabs some AD info (groups etc). Works rather well, only issues is the UGLY urls so far. But its fully working. Seems like a good setup. Other than having to rely on MYSQL (my company strives to be mainly SQL Server)

• Ray Generation Inconsistency

  - by Myx

  I have written code that generates a ray from the "eye" of the camera to the viewing plane some distance away from the camera's eye: R3Ray ConstructRayThroughPixel(...) { R3Point p; double increments_x = (lr.X() - ul.X())/(double)width; double increments_y = (ul.Y() - lr.Y())/(double)height; p.SetX( ul.X() + ((double)i_pos+0.5)*increments_x ); p.SetY( lr.Y() + ((double)j_pos+0.5)*increments_y ); p.SetZ( lr.Z() ); R3Vector v = p-camera_pos; R3Ray new_ray(camera_pos,v); return new_ray; } ul is the upper left corner of the viewing plane and lr is the lower left corner of the viewing plane. They are defined as follows: R3Point org = scene->camera.eye + scene->camera.towards * radius; R3Vector dx = scene->camera.right * radius * tan(scene->camera.xfov); R3Vector dy = scene->camera.up * radius * tan(scene->camera.yfov); R3Point lr = org + dx - dy; R3Point ul = org - dx + dy; Here, org is the center of the viewing plane with radius being the distance between the viewing plane and the camera eye, dx and dy are the displacements in the x and y directions from the center of the viewing plane. The ConstructRayThroughPixel(...) function works perfectly for a camera whose eye is at (0,0,0). However, when the camera is at some different position, not all needed rays are produced for the image. Any suggestions what could be going wrong? Maybe something wrong with my equations? Thanks for the help.

• SIGABRT on any UIView touch

  - by bitcruncher

  Hi. I'm afraid no amount of Googling has been able to save my hyde on this. I seem to be getting SIGABRT error anytime I touch the screen of the phone, on any UIView. The debugger console posts this error before the SIGABRT: .... [310:207] *** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0 .... [310:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0' (this is not my specific call to _exclusiveTouchView, of course.) I would gladly post some code, but the truth is I cannot find (or guess) where this problem may be coming from. This is not happening on any ONE UIView but on all the UIViews in my stack. I can summarize the display logic, though, perhaps that will shed some light. So the application is created and a UIWindow is alloc'd. A single viewcontroller is then alloc'd, which makes and adds its own blank self.view, to which the other UIViews, representing the different game states, are attached. Interestingly enough, this error is does NOT happen on the Simulator, but happens consistently on the device. And I should also mention that the application has yet to override/use any of the touchesBegan:/Ended:/Moved: etc... In other words, this error happens without these methods in the code. I'm really not understanding where this error is coming from... Any suggestions?

• Speeding up a soap powered website

  - by ChrisRamakers

  Hi all, We're currently looking into doing some performance tweaking on a website which relies heavily on a Soap webservice. But ... our servers are located in Belgium and the webservice we connect to is locate in San Francisco so it's a long distance connection to say the least. Our website is PHP powered, using PHP's built in SoapClient class. On average a call to the webservice takes 0.7 seconds and we are doing about 3-5 requests per page. All possible request/response caching is already implemented so we are now looking at other ways to improved the connection speed. This is the code which instantiates the SoapClient, what i'm looking for now is other ways/methods to improve speed on single requestes. Anyone has idea's or suggestions? private function _createClient() { try { $wsdl = sprintf($this->config->wsUrl.'?wsdl', $this->wsdl); $client = new SoapClient($wsdl, array( 'soap_version' => SOAP_1_1, 'encoding' => 'utf-8', 'connection_timeout' => 5, 'cache_wsdl' => 1, 'trace' => 1, 'features' => SOAP_SINGLE_ELEMENT_ARRAYS )); $header_tags = array('username' => new SOAPVar($this->config->wsUsername, XSD_STRING, null, null, null, $this->ns), 'password' => new SOAPVar(md5($this->config->wsPassword), XSD_STRING, null, null, null, $this->ns)); $header_body = new SOAPVar($header_tags, SOAP_ENC_OBJECT); $header = new SOAPHeader($this->ns, 'AuthHeaderElement', $header_body); $client->__setSoapHeaders($header); } catch (SoapFault $e){ controller('Error')->error($id.': Webservice connection error '.$e->getCode()); exit; } $this->client = $client; return $this->client; }

• [Java] Cluster Shared Cache

  - by GuiSim

  Hi everyone. I am searching for a java framework that would allow me to share a cache between multiple JVMs. What I would need is something like Hazelcast but without the "distributed" part. I want to be able to add an item in the cache and have it automatically synced to the other "group member" cache. If possible, I'd like the cache to be sync'd via a reliable multicast (or something similar). I've looked at Shoal but sadly the "Distributed State Cache" seems like an insufficient implementation for my needs. I've looked at JBoss Cache but it seems a little overkill for what I need to do. I've looked at JGroups, which seems to be the most promising tool for what I need to do. Does anyone have experiences with JGroups ? Preferably if it was used as a shared cache ? Any other suggestions ? Thanks ! EDIT : We're starting tests to help us decide between Hazelcast and Infinispan, I'll accept an answer soon. EDIT : Due to a sudden requirements changes, we don't need a distributed map anymore. We'll be using JGroups for a low level signaling framework. Thanks everyone for you help.

• Finding usage of jQuery UI in a big ugly codebase

  - by Daniel Magliola

  I've recently inherited the maintenance of a big, ugly codebase for a production website. Poke your eyes out ugly. And though it's big, it's mostly PHP code, it doesn't have much JS, besides a few "ajaxy" things in the UI. Our main current problem is that the site is just too heavy. Homepage weighs in at 1.6 Mb currently, so I'm trying to clean some stuff out. One of the main wasters is that every single page includes the jQuery UI library, but I don't think it's used at all. It's definitely not being used in the homepage and in most pages, so I want to only include the where necessary. I'm not really experienced with jQuery, i'm more of a Prototype guy, so I'm wondering. Is there anything I could search for that'd let me know where jQuery UI is being used? What i'm looking for is "common strings", component names, etc For example, if this was scriptaculous, i'd look for things like "Draggable", "Effect", etc. Any suggestions for jQuery UI? (Of course, if you can think of a more robust way of removing the tag from pages that don't use it without breaking everything, I'd love to hear about it) Thanks!! Daniel

• How do I so a select input for a STI column in a Rails model?

  - by James A. Rosen

  I have a model with single-table inheritance on the type column: class Pet < ActiveRecord::Base TYPES = [Dog, Cat, Hamster] validates_presence_of :name end I want to offer a <select> dropdown on the new and edit pages: <% form_for @model do |f| %> <%= f.label :name %> <%= f.text_input :name %> <%= f.label :type %> <%= f.select :type, Pet::TYPES.map { |t| [t.human_name, t.to_s] } %> <% end %> That gives me the following error: ActionView::TemplateError (wrong argument type String (expected Module)) I read a suggestion to use an alias for the field #type since Ruby considers that a reserved word that's the same as #class. I tried both class Pet < ActiveRecord::Base ... alias_attribute :klass, :type end and class Pet < ActiveRecord::Base ... def klass self.type end def klass=(k) self.type = k end end Neither worked. Any suggestions? Oddly, it works fine on my machine (MRI 1.8.6 on RVM), but fails on the staging server (MRI 1.8.7 not on RVM).

• KD-Trees and missing values (vector comparison)

  - by labratmatt

  I have a system that stores vectors and allows a user to find the n most similar vectors to the user's query vector. That is, a user submits a vector (I call it a query vector) and my system spits out "here are the n most similar vectors." I generate the similar vectors using a KD-Tree and everything works well, but I want to do more. I want to present a list of the n most similar vectors even if the user doesn't submit a complete vector (a vector with missing values). That is, if a user submits a vector with three dimensions, I still want to find the n nearest vectors (stored vectors are of 11 dimensions) I have stored. I have a couple of obvious solutions, but I'm not sure either one seem very good: Create multiple KD-Trees each built using the most popular subset of dimensions a user will search for. That is, if a user submits a query vector of thee dimensions, x, y, z, I match that query to my already built KD-Tree which only contains vectors of three dimensions, x, y, z. Ignore KD-Trees when a user submits a query vector with missing values and compare the query vector to the vectors (stored in a table in a DB) one by one using something like a dot product. This has to be a common problem, any suggestions? Thanks for the help.

• Lazy non-modifiable list

  - by mindas

  I was looking for a decent implementation of a generic lazy non-modifiable list implementation to wrap my search result entries. The unmodifiable part of the task is easy as it can be achieved by Collections.unmodifiableList() so I only need to sort out the the lazy part. Surprisingly, google-collections doesn't have anything to offer; while LazyList from Apache Commons Collections does not support generics. I have found an attempt to build something on top of google-collections but it seems to be incomplete (e.g. does not support size()), outdated (does not compile with 1.0 final) and requiring some external classes, but could be used as a good starting point to build my own class. Is anybody aware of any good implementation of a LazyList? If not, which option do you think is better: write my own implementation, based on google-collections ForwardingList, similar to what Peter Maas did; write my own wrapper around Commons Collections LazyList (the wrapper would only add generics so I don't have to cast everywhere but only in the wrapper itself); just write something on top of java.util.AbstractList; Any other suggestions are welcome.

• With regards to urllib AttributeError: 'module' object has no attribute 'urlopen'

  - by Matt

  import re import string import shutil import os import os.path import time import datetime import math import urllib from array import array import random filehandle = urllib.urlopen('http://www.google.com/') #open webpage s = filehandle.read() #read print s #display #what i plan to do with it once i get the first part working #results = re.findall('[<td style="font-weight:bold;" nowrap>$][0-9][0-9][0-9][.][0-9][0-9][</td></tr></tfoot></table>]',s) #earnings = '$ ' #for money in results: #earnings = earnings + money[1]+money[2]+money[3]+'.'+money[5]+money[6] #print earnings #raw_input() this is the code that i have so far. now i have looked at all the other forums that give solutions such as the name of the script, which is parse_Money.py, and i have tried doing it with urllib.request.urlopen AND i have tried running it on python 2.5, 2.6, and 2.7. If anybody has any suggestions it would be really welcome, thanks everyone!! --Matt ---EDIT--- I also tried this code and it worked, so im thinking its some kind of syntax error, so if anybody with a sharp eye can point it out, i would be very appreciative. import shutil import os import os.path import time import datetime import math import urllib from array import array import random b = 3 #find URL URL = raw_input('Type the URL you would like to read from[Example: http://www.google.com/] :') while b == 3: #get file name file1 = raw_input('Enter a file name for the downloaded code:') filepath = file1 + '.txt' if os.path.isfile(filepath): print 'File already exists' b = 3 else: print 'Filename accepted' b = 4 file_path = filepath #open file FileWrite = open(file_path, 'a') #acces URL filehandle = urllib.urlopen(URL) #display souce code for lines in filehandle.readlines(): FileWrite.write(lines) print lines print 'The above has been saved in both a text and html file' #close files filehandle.close() FileWrite.close()

• Send already generated MHTML using CDOSYS through C#?

  - by mutex

  I have a ready generated MHTML as a byte array (from Aspose.Words) and would like to send it as an email. I'm trying to do this through CDOSYS, though am open to other suggestions. For now though I have the following: CDO.Message oMsg = new CDO.Message(); CDO.IConfiguration iConfg = oMsg.Configuration; Fields oFields = iConfg.Fields; // Set configuration. Field oField = oFields["http://schemas.microsoft.com/cdo/configuration/sendusing"]; oField.Value = CDO.CdoSendUsing.cdoSendUsingPort; oField = oFields["http://schemas.microsoft.com/cdo/configuration/smtpserver"]; oField.Value = SmtpClient.Host; oField = oFields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"]; oField.Value = SmtpClient.Port; oFields.Update(); //oMsg.CreateMHTMLBody("http://www.microsoft.com", CDO.CdoMHTMLFlags.cdoSuppressNone, "", ""); // NEED MAGIC HERE :) oMsg.Subject = warning.Subject; // string oMsg.From = "[email protected]"; oMsg.To = warning.EmailAddress; oMsg.Send(); In this snippet, the warning variable has a Body property which is a byte[]. Where it says "NEED MAGIC HERE" in the code above I want to use this byte[] to set the body of the CDO Message. I have tried the following, which unsurprisingly doesn't work: oMsg.HTMLBody = System.Text.Encoding.ASCII.GetString(warning.Body); Anybody have any ideas how I can achieve what I want with CDOSYS or something else?
