• Violating 1st normal form, is it okay for my purpose?

  - by Nick

  So I'm making a running log, and I have the workouts stored as entries in a table. For each workout, the user can add intervals (which consist of a time and a distance), so I have an array like this: [workout] => [description] => [comments] => ... [intervals] => [0] => [distance] => 200m [time] => 32 [1] => [distance] => 400m [time] => 65 ... I'm really tempted to throw the "intervals" array into serialize() or json_encode() and put it in an "intervals" field in my table, however this violates the principles of good database design (which, incidentally, I know hardly anything about). Is there any disadvantage to doing this? I never plan on querying my table based on the contents of "intervals". Creating a separate table just for intervals seems like a lot of unnecessary complexity, so if anyone with more experience has had a situation like this, what route did you take and how did it work out?

• How is jQuery so fast?

  - by ClarkeyBoy

  Hey, I have a rather large application which, on the admin frontend, takes a few seconds to load a page because of all the pageviews that it has to load into objects before displaying anything. Its a bit complex to explain how the system works, but a few of my other questions explains the system in great detail. The main difference between what they say and the current system is that the customer frontend no longer loads all the pageviews into objects when a customer first views the page - it simply adds the pageview to the database and creates an object in an unsynchronised list... to put it simply, when a customer views a page it no longer loads all the pageviews into objects; but the admin frontend still does. I have been working on some admin tools on the customer frontend recently, so if an administrator clicks the description of an item in the catalogue then the right hand column will display statistics and available actions for the selected item. To do this the page which gets loaded (through $('action-container').load(bla bla bla);) into the right hand column has to loop through ALL the pageviews - this ultimately means that ALL the pageviews are loaded into objects if they haven't been already. For some reason this loads really REALLY fast. The difference in speed is only like a second on my dev site, but the live site has thousands of pageviews so the difference is quite big... So my question is: why is it that the admin frontend loads so slowly while using $(bla).load(bla); is so fast? I mean whatever method jQuery uses, can't browsers use this method too and load pages super-fast? Obviously not as someone would've done that by now - but I am interested to know just why the difference is so big... is it just my system or is there a major difference in speed between the browser getting a page and jQuery getting a page? Do other people experience the same kind of differences? Thanks in advance, Regards, Richard

• SimpleDOM sortedXPath date sorting works on localhost but not on remote server.

  - by Imminent

  Here's what i'm trying to do: 1) Take a basic XML page (data.xml) 2) Load it with simpleDOM 3) Use simpleDOM sortedXPath to sort all XML items by their pubDate 4) Display sorted output Here is the code I currently have. My code below outputs exactly what I need when run it on my localhost (XAMPP w/PHP 5.3) but on my remote server (which has at least PHP 5.0+) all is lost and a completely blank page is output. It will output the $xml array with print_r though. Here is my code: <?php include('SimpleDOM.php'); $xml = simpledom_load_file('data.xml'); $dateformat = "D j M, g:ia"; /* print_r($xml); <-array will output on remote server if put here, but alas nothing else beyond this point */ /*Output First 5 items sorted by pubDate*/ foreach($xml->channel->sortedXPath('item','pubDate', SORT_DESC) as $i => $item){ if ($i > 4){ break; } print "<p>This Weeks Deal:<strong> ".$item->title."</strong></p>"; print $item->description; print "<p>Date Posted:<strong> ".date($dateformat, strtotime($item->pubDate))."</strong></p>"; } ?> Like I said, this code seems to work great on my localhost... but not being able to run it on my remote server is making me crazy. Any ideas ?? Any help will be far beyond appreciated.

• Automation Error upon running VBA script in Excel

  - by brohjoe

  Hi guys, I'm getting an Automation error upon running VBA code in Excel 2007. I'm attempting to connect to a remote SQL Server DB and load data to from Excel to SQL Server. The error I get is, "Run-time error '-2147217843(80040e4d)': Automation error". I checked out the MSDN site and it suggested that this may be due to a bug associated with the sqloledb provider and one way to mitigate this is to use ODBC. Well I changed the connection string to reflect ODBC provider and associated parameters and I'm still getting the same error. Here is the code with ODBC as the provider: Dim cnt As ADODB.Connection Dim rst As ADODB.Recordset Dim stSQL As String Dim wbBook As Workbook Dim wsSheet As Worksheet Dim rnStart As Range Public Sub loadData() 'This was set up using Microsoft ActiveX Data Components version 6.0.

• form with multiple upload but allow no upload on edit problems

  - by minus4

  hiya i have a section that when created takes in images, however when you edit this item i dont want them to re-upload none changes images just to change a description or name. i have created this that deals with uploading files: public void UploadFiles(string currentFileName, FormCollection form) { // loop through all files in form post foreach (string file in Request.Files) { HttpPostedFileBase hpf = Request.Files[file]; // if no file is uploaded, we could be editing so set to current value if (hpf.ContentLength == 0) { form[file] = currentFileName; } else { //rename the file unique so we dont clash with names var filename = hpf.FileName.Replace(" ", "_").Replace(".", DateTime.Now.Date.Ticks + "."); UploadFileName = filename; hpf.SaveAs(Server.MapPath("~/Content/custom/" + filename)); // set the name of the file in our post to the new name form[file] = UploadFileName; } } // ensure value is still sent when no files are uploaded on edit if(Request.Files.Count <= 0) { UploadFileName = currentFileName; } } all works fine when only one image is required (CurrentFileName), however there is now a new image available taking it to a total of 2 images in the database therefor currentFileName is obsolete. has anyone tackled this and how as i have hit a wall with this one. thought of string[] currentFiles but cant see how to match this into string file in Request.Files. if it helps i am also working with models for the form so i could pass over the model but i dont think your able to do model.file without some kind of reflection. help much appreciated. thanks

• Trying to use a authlogic-connect as a plugin in place of gem - Server doesn't start

  - by Arkid

  I am trying to use Authlogic-connect as a plugin in Rails 3 in place of a gem. I have made an entry in the gemfile as gem "authlogic-connect", :require => "authlogic-connect", :path => "localgems" Now when I run the bundle install, it runs fine.

• Publishing my Website to my Local Disk Causes Exceptions to show Paths including my Local Disk

  - by coffeeaddict

  I've published my website many times. But didn't think about this though until I came across this issue. So I decided to publish my WAP project to a local folder on my C drive first. Then used FTP to upload it to my shared host on discountasp.net. I noticed during runtime that the stack trace was referencing that local folder still and erroring out. Anyone know what config settings are affected when publishing? Obviously something is still pointing to my local C drive and I've searched my entire solution and don't see why. Here's the runtime error I get when my code tries to run in discountasp.net's web server Cannot write into the public directory - check permissions Description: An unhandled exception occurred during the execution of the current web request.

• Catching MediaPlayer Exceptions from WPF MediaElement Control

  - by ScottCate

  I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

• Multiplication algorithm for abritrary precision (bignum) integers.

  - by nn

  Hi, I'm writing a small bignum library for a homework project. I am to implement Karatsuba multiplication, but before that I would like to write a naive multiplication routine. I'm following a guide written by Paul Zimmerman titled "Modern Computer Arithmetic" which is freely available online. On page 4, there is a description of an algorithm titled BasecaseMultiply which performs gradeschool multiplication. I understand step 2, 3, where B^j is a digit shift of 1, j times. But I don't understand step 1 and 3, where we have A*b_j. How is this multiplication meant to be carried out if the bignum multiplication hasn't been defined yet? Would the operation "*" in this algorithm just be the repeated addition method? Here is the parts I have written thus far. I have unit tested them so they appear to be correct for the most part: The structure I use for my bignum is as follows: #define BIGNUM_DIGITS 2048 typedef uint32_t u_hw; // halfword typedef uint64_t u_w; // word typedef struct { unsigned int sign; // 0 or 1 unsigned int n_digits; u_hw digits[BIGNUM_DIGITS]; } bn; Currently available routines: bn *bn_add(bn *a, bn *b); // returns a+b as a newly allocated bn void bn_lshift(bn *b, int d); // shifts d digits to the left, retains sign int bn_cmp(bn *a, bn *b); // returns 1 if a>b, 0 if a=b, -1 if a<b

  Hi, for creating a columns I worked on this code . and for creating document library Lists listService = new Lists(); listService.PreAuthenticate = true; listService.Credentials = new NetworkCredential(username,password,domain; String url = "http://YourServer/SiteName/"; listService.Url = url @ + /_vti_bin/lists.asmx"; XmlNode ndList = listService.AddList(NewListName, "Description", 101); Both are working successfully. But Problem i am facing is: New Columns and document library are not visible. I tried with comparing Field Value of Both Visible and No-Visible types. Difference i found is : Visible (Created Manually) doesn't contain Version value. were as i am creating have it. Can you help me out in this? EDIT: I checked contents of ndList node, List is created and it is visible on my UI. but on sharepoint it should be listed in 'Document' tab where default 'Shared Documents' library is shown. If i click on 'Documents' then we can also see all lib created by this code. Visible means library displayed under 'Documents' tab

• PJSIP Custom Registration Header (iOS)

  - by Daniel Redington

  I am attempting to setup SIP communication with an internal server (using the PJSIP library), however, this server requires a custom header field with a specified header value for the REGISTRATION call. For example's sake we'll call this required header "MyHeader". From what I've found, the pjsua_acc_add() function will add an account and register it to the server using a config struct. The parameter "reg_hdr_list" of the config struct has the description "The optional custom SIP headers to be put in the registration request." Which sounds like exactly what I need, however doesn't seem to have any effect on the call itself. Here's what I have so far: pjsua_acc_config cfg; pjsua_acc_config_default(&cfg); //...Some other config stuff related to the server... pjsip_hdr test; test.name = pj_str("MyHeader"); test.sname = pj_str("MyHdr"); test.type = PJSIP_H_OTHER; test.prev = cfg.reg_hdr_list.prev; test.next = cfg.reg_hdr_list.next; cfg.reg_hdr_list = test; pj_status_t status; status = pjsua_acc_add(&cfg, PJ_TRUE, &acc_id); From the server side, there are no extra header fields or anything. And the struct that is used to define the header (pjsua_hdr) has no "value" or equivalent field, so even if it did create the header, how does it set the value? Here's the refrence for the header list definition: Link And the reference for the header struct: Link Any help would be greatly appreciated!

• Automate the signature of the update.rdf manifest for my firefox extension

  - by streetpc

  Hello, I'm developing a firefox extension and I'd like to provide automatic update to my beta-testers (who are not tech-savvy). Unfortunately, the update server doesn't provide HTTPS. According to the Extension Developer Guide on signing updates, I have to sign my update.rdf and provide an encoded public key in the install.rdf. There is the McCoy tool to do all of this, but it is an interactive GUI tool and I'd like to automate the extension packaging using an Ant script (as this is part of a much bigger process). I can't find a more precise description of what's happening to sign the update.rdf manifest than below, and McCoy source is an awful lot of javascript. The doc says: The add-on author creates a public/private RSA cryptographic key pair. The public part of the key is DER encoded and then base 64 encoded and added to the add-on's install.rdf as an updateKey entry. (...) Roughly speaking the update information is converted to a string, then hashed using a sha512 hashing algorithm and this hash is signed using the private key. The resultant data is DER encoded then base 64 encoded for inclusion in the update.rdf as an signature entry. I don't know well about DER encoding, but it seems like it needs some parameters. So would anyone know either the full algortihm to sign the update.rdf and install.rdf using a predefined keypair, or a scriptable alternative to McCoy whether a command-line tool like asn1coding will suffise a good/simple developer tutorial on DER encoding

• fluent nHibernate mapping of subclassed structure

  - by Codezy

  I have a workflow class that has a collection of phases, each phase has a collection of tasks. You can design a workflow that will be used by many engagements. When used in engagement I want to be able to add properties to each class (workflow, phase, and task). For example a task in the designer does not have people assigned, but a task in an engagement would need extra properties like who is assigned to it. I have tried many different approaches using subclasses or interfaces but I just can't get it to map the way I want. Currently I have the engagement level versions as subclasses, but I can't get Engagement phases to map to engagement workflows. Public Class WorkflowMapping Inherits ClassMap(Of Workflow) Sub New() Id(Function(x As Workflow) x.Id).Column("Workflow_Id").GeneratedBy.Identity() Map(Function(x As Workflow) x.Description) Map(Function(x As Workflow) x.Generation) Map(Function(x As Workflow) x.IsActive) HasMany(Function(x As Workflow) x.Phases).Cascade.All() End Sub End Class Public Class EngagementWorkflowMapping Inherits SubclassMap(Of EngagementWorkflow) Sub New() Map(Function(x As EngagementWorkflow) x.ClientNo) Map(Function(x As EngagementWorkflow) x.EngagementNo) End Sub End Class How would you approach mapping this in fluent (or hbm) so that you could load just the workflow base class when designing the flow, or the engagement subclass versions of each when being used by an engagement?

• Checkstyle: cannot summarise issues per author ?

  - by David Michel

  Hi all, I'm trying to use checkstyle for a java project but I can't seem to get it working properly: While it apparently runs smoothly, the html report doesn't give any info per authors as it should, i.e. the authors table is empty. The thing is I don't know how checkstyle identify an author. Does it look at the java doc tag @author ? at the class level or at the method level ? The ant task I used is below: <taskdef resource="checkstyletask.properties" classpath="${libs.dir}/checkstyle-all-5.0.jar"/> <target name="checkstyle" description="Generates a report of code convention violations."> <mkdir dir="${checkstyle.dir}"/> <checkstyle config="${util.dir}/checkstyle/sun_checks.xml" failureProperty="checkstyle.failure" failOnViolation="false"> <formatter type="xml" tofile="${checkstyle.dir}/checkstyle_report.xml"/> <fileset dir="${src.dir}" includes="**/*.java"/> </checkstyle> <xslt in="${checkstyle.dir}/checkstyle_report.xml" out="${checkstyle.dir}/checkstyle_report.html" style="${util.dir}/checkstyle/checkstyle-author.xsl"/> </target> Many thanks for your help David

Put main website in Facebook. Create a Youtube channel. Invest in Adwords. Invest in other online advertising companies. Use sitemap.xml and Google Webmaster tools. Use Google Trends to analyze the volume of searches of certain keywords. Use Google Analytics to analyze weak points and good points of your site, and find new oportunities in keywords. Use tools to find new keywords related with your content. Do you have some internet links, or knowledge about all the tasks that a SEO Expert should do? Could you share some knowledge about what kind of business could be do with another companies (B2B) to increase the search engine position of those product pages. Do you know more tecniques about how to get more inbound links? (i only know the link interchange) Thanks in advance. Best Regards. Jose.

• SQL database problems with addressbook table design

  - by Sebastian Hoitz

  Hello! I am writing a addressbook module for my software right now. I have the database set up so far that it supports a very flexible address-book configuration. I can create n-entries for every type I want. Type means here data like 'email', 'address', 'telephone' etc. I have a table named 'contact_profiles'. This only has two columns: id Primary key date_created DATETIME And then there is a table called contact_attributes. This one is a little more complex: id PK #profile (Foreign key to contact_profiles.id) type VARCHAR describing the type of the entry (name, email, phone, fax, website, ...) I should probably change this to a SET later. value Text (containing the value for the attribute). I can now link to these profiles, for example from my user's table. But from here I run into problems. At the moment I would have to create a JOIN for each value that I want to retrieve. Is there a possibility to somehow create a View, that gives me a result with the type's as columns? So right now I would get something like #profile type value 1 email [email protected] 1 name Sebastian Hoitz 1 website domain.tld But it would be nice to get a result like this: #profile email name website 1 [email protected] Sebastian Hoitz domain.tld The reason I do not want to create the table layout like this initially is, that there might always be things to add and I want to be able to have multiple attributes of the same type. So do you know if there is any possibility to convert this dynamically? If you need a better description please let me know. Thank you!

• UIWebViewDelegate returns different error message on iPod Touch 2G and 3G

  - by lostInTransit

  Hi I have an app developed using SDK 3.0. My view has a UIWebView whose delegate is the viewcontroller. I want to show an error message when the webview does not load (in case the touch goes out of wifi range or wifi is turned off) I override this method to show an alert - (void)webView:(UIWebView *)wbView didFailLoadWithError:(NSError *)error But this caused an issue when some links were clicked on the webview. The page loaded but if some images from the previous page were not loaded, the method call was triggered. Testing on an iPod Touch 3G, the NSError's userInfo has the localized description as no Internet connection if load fails due to no internet connection. But this only seems to be true for an iPod Touch 3G. 2G shows a different message (I got to know from some beta testers. They aren't very technical so can't tell them to get me the logs or anything.) Can anyone with an iPod Touch 2G tell me the values for the NSError userInfo? Or better still, did anyone else face this issue? How did you resolve it? Thanks.

• asp.Net 2005 "Could not load type"

  - by Melody Friedenthal

  Although I have seen dozens of forum questions relating to "Could not load type", none of the advice in them seemed to apply to my situation. I wrote a new web application using aspx.net VB 2005. It is tiny, with just 2 pages, 1 of which has no code-behind. It runs aok in the IDE but when I installed it on my pc (and also when installed on the production server), and tried to run it this error came up: Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'EMTTrainingDatabase.pageMain'. Source Error: Line 1: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="pageMain.aspx.vb" Inherits="EMTTrainingDatabase.pageMain" %> Line 2: Line 3: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Source File: /EMTTrainingDatabase/pageMain.aspx Line: 1 -------------------------------------------------------------------------------- Version Information: Microsoft .NET Framework Version:2.0.50727.3603; ASP.NET Version:2.0.50727.3082 I checked the web site properties in IIS and the correct ASP.net version is specified: 2.0.50727. I checked the virtual path and it looks correct too: /EMTTrainingDatabase pageMain source code header looks like: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="pageMain.aspx.vb" Inherits="EMTTrainingDatabase.pageMain" %> Some posters suggest that the bin is in the wrong folder or the bin doesn't contain the rigt contents. I don't have enough knowledge to evaulate this. Can someone help? Thank you.
