  • Sort Java List/Map by order in which items are in an XML File

    - by Brandon Smith
    Hello everyone, What I'm looking to do is to sorta a Java List or Map in the order the items are in a XML File. For Example I have a list of function names as so: functionOne functionThree functionTwo The XML File looks like this: <xml> <function>functionOne</function> <function>functionTwo</function> <function>functionThree</function> </xml> So I would like to sort the list so the function names are as so: functionOne functionTwo functionThree Now Im trying to do this for Variables as well, so there are around 500+ unique 'items'. Does anyone have any idea how I can go about doing this? Now for the file that determines that sort order doesn't have to be XML it just what I use the most, it can be anything that can get the job done. Thanks in advance for your time.

  • VB app to web service

    - by brandon
    I know very little about web service but I assumed it would be the solution I was looking for. Basically I made an application in VB that I want to be ubiquitous for a lack of a better word. I need it to receive requests from multiple users and respond all at once. I was told "technically if you write a webservice you can provide as many results back to users as are connected." Maybe there is another solution for me that will give me the results I want. Here is an example of what I'm trying to do. Lets say I make an application in VB that does math. I now make a website. My website allows for a person to input 1 + 1 they click submit and my website then connects to my VB application running on my server listening for a request. It accepts the request from my website, and then it solves the math problem and returns the answer back to the website "1 + 1 = 2" That is only an example of the type of thing I need. My problem is that I can't have multiple people visiting my website all connecting to that same application running on my server so somehow I need the application to be where it can be accessed by multiple users. I was told a web service would be the answer but if there is another solution I'd like to know. If the only solution is a web service, then how can I manage to either convert the VB app to a web service? Can I have to convert the app to asp.net or some other language? Is there an easier option?

  • Is there a web tool framework for building a video editing/manipulation widget other than custom Fla

    - by Brandon
    I am looking to build a widget for a site which allows users to tag images from individual frames of a video file but would prefer not to have to build a custom Flash tool. Is there an existing free library or framework which simplifies things like this in a webapplication setting? Features would also involve basic video playback functionality as well as time-driven meta-data and the ability to extract images from individual video frames. Are there existing open-source web-based tools for video manipulation other than building your own custom Flash app?

  • How to deal with missing items the SEO way?

    - by Brandon Montgomery
    I am working on a public-facing web site which serves up articles for people to read. After some time, articles become stale and we remove them from the site. My question is this: what is the best way to handle the situation when a search engine visits a URL corresponding to a removed article? Should the app respond with a permanent redirect (301 Moved Permanently) to a "article not found" page, or is there a better way to handle this?

  • Merge two data frames together that have the same variable names and data types

    - by Brandon
    I have tried the merge function to merge two csv files that I imported. They both have the same variable names and data types but each time I run merge all that I get is an object that contains the names of the two data frames. I have tried the following: # ex1 obj <- merge(obj1, obj2, by=obj) # ex2 obj <- merge(obj1, obj2, all) and several other iterations of the above. Is merge the correct function? If so, what am I doing wrong?

  • How would I initialize these two lists so that modifying one doesn't modify the other?

    - by Brandon
    I'm aware of why this is happening, but is there any way to do this without having to implement ICloneable or a Copy() method? Preferably .net 2.0, but 3.5 is fine if it is necessary. Essentially I'm trying to implement an undo method. In most cases I can just perform the reverse action in the Undo(), but for others that is not possible. So I want to keep two lists. One for the list of items that I will be modifying, and one for the original, unmodified list of items. This way if I need to do an undo, I just delete the modified items and replace them with the originals. Most of the ways I've tried to assign the _originalItems variable doesn't work, so what would I need to do? public MyClass(List<SelectedItems> selectedItems) { _selectedItems = new List<SelectedItems>(selectedItems); _originalItems = ?? }

  • How do I make a function in SQL Server that accepts a column of data?

    - by brandon k
    I made the following function in SQL Server 2008 earlier this week that takes two parameters and uses them to select a column of "detail" records and returns them as a single varchar list of comma separated values. Now that I get to thinking about it, I would like to take this table and application-specific function and make it more generic. I am not well-versed in defining SQL functions, as this is my first. How can I change this function to accept a single "column" worth of data, so that I can use it in a more generic way? Instead of calling: SELECT ejc_concatFormDetails(formuid, categoryName) I would like to make it work like: SELECT concatColumnValues(SELECT someColumn FROM SomeTable) Here is my function definition: FUNCTION [DNet].[ejc_concatFormDetails](@formuid AS int, @category as VARCHAR(75)) RETURNS VARCHAR(1000) AS BEGIN DECLARE @returnData VARCHAR(1000) DECLARE @currentData VARCHAR(75) DECLARE dataCursor CURSOR FAST_FORWARD FOR SELECT data FROM DNet.ejc_FormDetails WHERE formuid = @formuid AND category = @category SET @returnData = '' OPEN dataCursor FETCH NEXT FROM dataCursor INTO @currentData WHILE (@@FETCH_STATUS = 0) BEGIN SET @returnData = @returnData + ', ' + @currentData FETCH NEXT FROM dataCursor INTO @currentData END CLOSE dataCursor DEALLOCATE dataCursor RETURN SUBSTRING(@returnData,3,1000) END As you can see, I am selecting the column data within my function and then looping over the results with a cursor to build my comma separated varchar. How can I alter this to accept a single parameter that is a result set and then access that result set with a cursor?

  • Jquery failure after site went live

    - by Brandon Condrey
    I have been designing a site for weeks using JQuery. I don't have a local server or a testing server so I just created a directory through FTP, '/testing'. Everything was working great in the testing directory. I attempted to go live tonight by moving all the files in '/testing' to the root directory and I changed all file paths and script sources accordingly. The site loads, but everything related to JQuery is non-functional. Javascript console gives errors of (just as an example from a plugin): '$.os.name' is not a function I'm at loss for what to do. I changed the paths referencing the JQuery library, installed a fresh copy of JQuery (to a new directory), etc. There is a wordpress installation in a different directory '/blog'. I've read about some compatibility issues with wordpress, but that seems to be related to using JQuery inside wordpress, which I am not. I'm not sure if any code would be beneficial since it was all functional in a different directory. Your help is greatly appreciated.

  • Handling a mix of server side code and html in a resource file?

    - by Brandon
    I'm trying to convert an ASP.NET web application to use resource files. I haven't used resource files before, so I'm just toying around with them and was wondering if this is possible. I have a message that returns from a search when no results are found, that prompts the user to return to the home page. A lot of these pages have methods to determine what is the proper page to send the user to, so there are many sections with markup similar to this: Sorry, but we could not find an item matching your search criteria. Please adjust your search criteria or <a href="<%= SomeMethodToDetermineUri() %>">return to (SomePage)</a>. So basically, some type of message, followed by a link or a list of links. Getting the message part works fine, it's the server side code to generate links thats the problem. What is the best way to put that into a resource file? It is able to recognize the html link part just fine, but the server side code gets inserted as plain text. Is the only way to break it into 2 resources? (Which seems messy) <%= Resources.Master.NoSearchResultsFound %> <a href="<%= SomeMethodToDetermineUri() %>"> <%= Resources.Master.NoSearchResultsFoundReturnLinkText %> </a>. Or is there a way to get the page to evaluate the server code?

  • Recaptcha with Ajax error

    - by Brandon
    I'm having trouble validating a recaptcha input. Heres my code: // Validate Recaptcha Input var challenge = $("#recaptcha_challenge_field").val(); var response = $("#recaptcha_response_field").val(); var dataString = 'recaptcha_challenge_field=' + challenge + '&recaptcha_response_field=' + response; var html = $.ajax({ type: "POST", url: "PHP/recaptchaverify.php", data: dataString, async: true }).responseText; console.log(html); if(html == 'accept') { alert("CORRECT"); } else { alert("The reCAPTCHA wasn't entered correctly. Go back and try it again."); $("#recaptcha_response_field").focus(); Recaptcha.reload(); return false; } Now I passed my variables to recpatchaverify.php require_once('../scripts/recaptcha-php/recaptchalib.php'); $privatekey = "MYKEY"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered incorrectly echo "error"; } else { // Your code here to handle a successful verification echo "accept"; } Now my problem is the html variable is displaying "accept" whenever I enter the Recaptcha correctly, but it won't work in the IF statement?

  • How to research unmanaged memory leaks in .NET?

    - by Brandon
    I have a WCF service running over MSMQ. Memory gradually increases over time, indicating that there is some sort of memory leak. I ran the service locally and monitored some counters using PerfMon. Total CLR memory managed heap bytes remains relatively constant, while the process' private bytes increases over time. This leads me to believe that there is some sort of unmanaged memory leak. Assuming that unmanaged memory leak is the issue, how do I address the issue? Are there any tools I could use to give me hints as to what is causing the unmanaged memory leak? Also, all my service is doing is reading from the transactional queue and writing to a database, all as part of a DTC transaction (handled under the hood by requiring a transaction on the service contract). I am not doing anything explicitly with COM or DllImports. Thanks in advance!

  • Inexplicably slow query in MySQL

    - by Brandon M.
    Given this result-set: mysql> EXPLAIN SELECT c.cust_name, SUM(l.line_subtotal) FROM customer c -> JOIN slip s ON s.cust_id = c.cust_id -> JOIN line l ON l.slip_id = s.slip_id -> JOIN vendor v ON v.vend_id = l.vend_id WHERE v.vend_name = 'blahblah' -> GROUP BY c.cust_name -> HAVING SUM(l.line_subtotal) > 49999 -> ORDER BY c.cust_name; +----+-------------+-------+--------+---------------------------------+---------------+---------+----------------------+------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+---------------------------------+---------------+---------+----------------------+------+----------------------------------------------+ | 1 | SIMPLE | v | ref | PRIMARY,idx_vend_name | idx_vend_name | 12 | const | 1 | Using where; Using temporary; Using filesort | | 1 | SIMPLE | l | ref | idx_vend_id | idx_vend_id | 4 | csv_import.v.vend_id | 446 | | | 1 | SIMPLE | s | eq_ref | PRIMARY,idx_cust_id,idx_slip_id | PRIMARY | 4 | csv_import.l.slip_id | 1 | | | 1 | SIMPLE | c | eq_ref | PRIMARY,cIndex | PRIMARY | 4 | csv_import.s.cust_id | 1 | | +----+-------------+-------+--------+---------------------------------+---------------+---------+----------------------+------+----------------------------------------------+ 4 rows in set (0.04 sec) I'm a bit baffled as to why the query referenced by this EXPLAIN statement is still taking about a minute to execute. Isn't it true that this query only has to search through 449 rows? Anyone have any idea as to what could be slowing it down so much?

  • Using new (this) to reuse constructors

    - by Brandon Bodnar
    This came up recently in a class for which I am a teaching assistant. We were teaching the students how to do copy constructors in c++, and the students who were originally taught java asked if you can call one constructor from another. I know the answer to this is no, as they are using the pedantic flag for their code in class, and the old standards do not have support for this. I found on Stackoverflow and other sites a suggestion to fake this using new (this) such as follows class MyClass { private: int * storedValue; public: MyClass(int initialValue = 0) { storedValue = new int(initialValue); } ~ MyClass() { delete storedValue; } MyClass(const MyClass &b) { new (this) MyClass(*(b.storedValue)); } int value() { return *storedValue; } }; This is really simple code, and obviously does not save any code by reusing the constructor, but it is just for example. My question is if this is even standard compliant, and if there are any edge cases that should be considered that would prevent this from being sound code?

  • Lucene Search Returning Extra, Undesired Records

    - by Brandon
    I have a Lucene index that contains a field called 'Name'. I escape all special characters before inserting a value into my index using QueryParser.Escape(value). In my example I have 2 documents with the following names respectively: Test Test (Test) They get inserted into my index as such (I can confirm this using Luke): [test] [test] [\(test\)] I insert these values as TOKENIZED and using the StandardAnalyzer. When I perform a search, I use the QueryParser.Escape(searchString) against my search string input to escape special characters and then use the QueryParser with my 'Name' field and the StandardAnalyzer to perform my search. When I perform a search for 'Test', I get back both documents in my index (as expected). However, when I perform a search for 'Test (Test)', I am getting back both documents still. I realize that in both examples it matches on the 'test' term in the index, but I am confused in my 2nd example why it would not just pull back the document with the value of 'Test (Test)' because my search should create two terms: [test] and [\(test\)] I would imagine it would perform some sort of boolean operator where BOTH terms must match in that situation so I would get back just one record. Is there something I am missing or a trick to make the search behave as desired?

  • How can I set default seed for all identities within a SQL Server database?

    - by Brandon DuRette
    Is there a way to tell SQL server to use specific default seed value for IDENTITY columns - assuming the (to be run) CREATE TABLE statements do not specify one? I don't really care about altering existing data or altering the seed values for specific IDENTITY columns. I want the same seed for all newly created identity columns. Assume I cannot modify the individual CREATE TABLE statements in any way.

  • Javascript not executing (I included format.js)

    - by Brandon
    I added format.js to my controller, yet I still cannot get the js in index.js.erb to execute when I view my index page. The only thing I can figure out is that it must be because of the model name. I had to add ActiveSupport::Inflector.inflections do |inflect| inflect.irregular 'business', 'businesses' end to my inflections.rb file...because my model is called Business. my views/js are located at views/businesses/* Please help before I pull my hair out! All I have in the index.js.erb file is: alert(1); Obviously the goal is that I will get an alert when I finally get the issue fixed, letting me know it is working.

  • Sorting results by a char(1) column

    - by Brandon
    I have a stored procedure which basically does something like select top 1 expiryDate, flag, (bunch of other columns) from someTable (bunch of joins) order by expiryDate desc So this will grab the record that expires last. This works for most cases, except some records have a flag that are just a char(1). Most of the time it's just Y or N. So it'll return something like 2010-12-31 N 2010-10-05 Y 2010-08-05 N 2010-03-01 F 2010-01-31 N This works, most of the time, but is there any way to order it by the Flag column as well? So I'd want to group the results by Y, then N, and F and any other flags can go last in any order. I thought this would just be an order by, but since the flags are not weighted by the alphabetic value, I'm a little stumped. (Note: These are not my tables, I don't know if using the characters like this was a good idea or not, but it's not something I can change).

  • D&rsquo;Arcy&rsquo;s Book Club - The New Strategic Selling

    - by D'Arcy Lussier
    The New Strategic Selling Miller and Heiman Amazon.ca Amazon.com Chapters Everybody is a salesmen. Every day, without knowing it, we sell something to someone. Now, the typical vision people think of when they hear the word “sales” is the sleazy used car salesperson who does whatever they can to get you to buy the clunker on their lot. But selling is not an action tied to money and products. Selling is about convincing people to see your point of view and act on it. If you want your company to cover a trip to a conference, you may have to sell the idea to your boss. If you want to buy that new big screen TV, you have to sell the idea to your significant other. If you want to go on a weekend fishing trip with the boys you might be called in to help sell the idea to your buddies wife. We all sell, but we don’t all sell very well. So enter The New Strategic Selling, a book based on the sales course put on by the Miller-Heiman group. In fact, this isn’t really a “New” strategy to selling as its been around for a number of years. But the concepts they present, the ideas about selling, these are still very radical based on what most of us have experienced. Gone are the high pressure, win at all cost, GlenGarry-GlenRoss style of sales…instead the book presents a framework to switch to need-based selling. It’s the idea that instead of going in raving about a product or service, you build a relationship where the buyer expresses what their needs are and your response is to present a solution that best fits that need. Instead of focussing on the amount of money you can squeeze out of a client, you focus on whether everyone wins, that they receive win-results from the engagement, that repeat business is developed over time delivering value over and over again. The great thing about the book is that what it teaches…things like how to identify different buying influencers, how to prepare for meetings, techniques to solicit information about what the buyer is really thinking/feeling…these things are entirely applicable in *any* situation that you need to sell to someone…and remember: selling is convincing people to see your point of view and act on it. So that new big screen TV you want to buy but need to convince your wife on? This book can help you. That training opportunity you want your company to send you on? This book can help you. The upgrade to your community park that you want to lobby the local civic authorities for? This book can help you. The book is a bit wordy. I found that the length could have been reduced and the points still have gotten across. That’s really the only knock that I have though; the insight that it provides is so worthwhile that having to chew through extra words is well worth it. You definitely don’t have to be a professional salesperson to benefit from this book. Rating: 4/5

  • Translating EventAggregators usage of SynchronizationContext to VB.Net

    - by Phil Sayers
    Working with a fairly large VB.Net back office winforms application. 1 million+ LOC. Big ball of mud, 90% of all code is in Forms & other UI controls. Slowly introducing better architecture as time & recources allows, We've been using ideas from the EventAggrgator by Jeremy Miller. http://codebetter.com/blogs/jeremy.miller/archive/2008/01/11/build-your-own-cab-extensible-pub-sub-event-aggregator-with-generics.aspx Initially I stripped out the usage of SynchronizationContext. Now I'm trying to introduce it back, and I'm struggling with the translation of the lamda stuff from c# to vb.net. Specifically this line of c# _context.Send(delegate { receiver.Handle(subject); }, null); This is the vb.net I have so far: _context.Send(New SendOrPostCallback(AddressOf listener.Handle(message)), Nothing) The error I'm getting is listener.Handle(message) <-- AddressOf operand must be the name of a method. I'm sure I'm missing something simple, but after staring at this for 2 days, I'm lost.
