• pl/sql does not work with %rowtype

  - by Manolo

  I want to do a simple PL/SQL program on the Oracle 10g internet environment. The program is: DECLARE stud_rec students%ROWTYPE; last_name VARCHAR2:='Clinton'; BEGIN SELECT * INTO stud_rec FROM students WHERE student_id=100; END; I have a table called students with data inside of it. The issue is that when I want to run this in the SQL command window I got this message: ORA-06550: line 3, column 11: PLS-00215: String length constraints must be in range (1 .. 32767) I have checked the syntax and I cannot find the error. Any help? Thanks in advance

• Workflow Foundation: Asynchronous operations (lengthy network I/O)

  - by StormianRootSolver

  I have to create an application that will be started a few times per day (it's non - interactive). To operate, it needs LARGE amounts of data from the Internet (megabytes) via a rather slow connection, so the WCF service calls take quite some time. At the same time, it needs to perform local calculations and has a sophisticated initialization process. So, what I want to do is to create a workflow that asynchronously fetches the data (takes a few minutes) while already initializing / calculating locally. Is there a way to accomplish this?

• Problem indexing files in Solr on Ubuntu

  - by nik

  Hi, What I want to do is index some documents in Solr and know how it works. I have installed Solr and Tomcat and can see Solr Admin UI at localhost:8080/ solr/ admin/ Now, I want to add some documents to the index, may I know how to proceed further? I find very less documentation on Internet regarding this. In the tutorial http://lucene.apache.org/solr/tutorial.html#Indexing+Data they asked to run java -jar post.jar solr.xml monitor.xml command but after running that I get connection refused error as it is jetty. After installing jetty I tried telnet: I get "Connection refused" error I am not able to understand what the problem is.

• How to do query auto-completion/suggestions in Lucene?

  - by Mat Mannion

  I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

• How to return the full file path in a C# / ASP.NET web application?

  - by salvationishere

  This should be really simple, but I have tried many solutions posted on the internet so I thought I'd give this a try here. I have a VS 2008 web application that I need to capture the full file path (directories and file name) from the selected file. So user selects a file and then clicks on one of the buttons which transfers control to my code for processing. So how do I get the file path? I can get the file name, but not the path. Thanks!

• Answers to Conference Revenue Tweet Questions

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2014/05/27/156612.aspxI tweeted this the other day… …and I had some people tweet back questioning/asking about the profit number. So here’s how I came to that figure. Total Revenue Let’s talk total revenue first. This conference has a huge list of companies/organizations paying some amount for sponsorship. Platinum ($1500) x 5 = $7500 Gold ($1000) x 3 = $3000 Silver ($500) x 9 = $4500 Bronze ($250) x 13 = $3250 There’s also a title sponsor level but there’s no mention of how much that is…more than $1500 though, so let’s just say $2500. Total Sponsorship Revenue: $20750.00 For registrations, this conference is claiming over 300 attendees. We’ll just calculate at 300 and the discounted “member rate” – $249. Total Registration Revenue: $74700.00 Booth space is also sold for a vendor area, but let’s just leave that out of the calculation. Total Event Revenue: $95450.00 Now that we know how much money we’re playing with, let’s knock out the costs for the event. Total Costs Hard Costs Audio/Visual Services $2000 Conference Rooms (4 Breakouts + Plenary) $2500 Insurance $700 Printing/Signage $1500 Travel/Hotel Rooms $2000 Keynotes $2000 So let’s talk about these hard costs first. First you may be asking about the Audio Visual. Yes those services can be that high, actually higher. But since there’s an A/V company touted as the official A/V provider, I gotta think there’s some discount for being branded as such. Conference rooms are actually an inflated amount of $500 per. Venues make money on the food they sell at events, not on room rentals. The more food, the cheaper the rooms tend to be offered at. Still, for the sake of argument, let’s set the rooms at $500 each knowing that they could be lower. For travel and hotel rooms…it appears that most of the speakers at this conference are local, meaning there’s no travel or hotel cost. But a few of them I wasn’t too sure…so let’s factor in enough to cover two outside speakers (airfare and hotel). There are two keynotes for this event and depending on the event those may be paid gigs. I’m not sure if they are or not, but considering the closing one is a comedian I’m going to add some funds here for that just in case. Total Hard Costs: $10700 Now that the hard costs are out of the way, let’s talk about the food costs. Food Costs The conference is providing a continental breakfast (YEEEESH!), some level of luncheon, and I have to assume coffee breaks in between. Let’s look at those costs. Continental Breakfast $12 per person Lunch Buffet $18 per person Coffee Breaks (2) $6 per person (or $3 a cup) Snacks (2) $10 per person (or $5 each) Note that the lunch buffet assumes a *good* lunch buffet – two entrees, starch, vegetable, salads, and bread. Not sure if there’ll be snacks during coffee breaks but let’s assume so. Total Food Cost Per Person: $46 Food Cost: $14950 Gratuity: $2691 Total Food Cost: $17641 Total food cost is based on the $46 per person cost x 325. 300 for attendance, 12 for speakers, extra 13 for volunteers/organizers. Gratuity is 18%. Grand Totals So let’s sum things up here. Total Costs Hard Costs: $10700.00 Food Costs: $17641.00 Total:          $28341.00 Taxes:         $3685.00 Grand Total  $32026.00 Total Revenue Sponsorship  $20750 Registration   $74700 Grand Total   $95450.00 Total Profit $63424.00 Now what if the registration numbers were lower and they only got 100 people to show up. In that scenario there’d still be a profit of just under $26000. Closing Comments A couple of things to note: - I haven’t factored in anything for prizes. Not sure if any will be given out - We didn’t add in the booth space revenue - We’re assuming speakers aren’t getting paid, but even if they were at the high end its $12000 ($1000 per session), which is probably an inflated number for local speakers. - Note that all registrations were set to the “member” discounted price. The non-member registration price is higher. There is also an option for those that just want to show up for the opening keynote. There you have it! Let me know if you have any questions. D

• $.ajax working with Firefox, not IE

• Real-Time Data Streaming to Multiple Clients

  - by AriX

  Hi all, I would like to write an application which will stream data at 2400 baud over the internet from a server to multiple clients. The data will be the same for each client, and it would probably be fine to send it as a UDP stream, since exact data accuracy is not a 100% necessity, as there are checksums built-in to the data format and the data will be sent repeatedly on a loop. What is the best way to do this? I would want to write the server in C, but I don't know how to best multicast this data to the different clients that would be receiving it all over the country. I'm sure this seems like a pretty draconian way to go about my project, as opposed to just using some sort of fetch command, but I'd prefer to do it this way if possible.

• Which video format(s) should a webapp serve?

  - by NoozNooz42

  I need to put up a few videos on a Webapp and I'm a bit lost. My requirements are: DRM is not a concern at all it should work on the iPhone (and iPad) and on the main browsers (Safari, Internet Explorer, Firefox, Opera). it is not a problem at all if the video doesn't play on Linux (because it's a video/screencast of a Windows/OS X software targetted at, well, Windows and OS X users) it is not a problem at all if it also works on Linux (I'm a Linux user myself) Can a unique format be served (like H.264) and play without any additional work on my part or do I need to convert the videos to different formats and have the webapp serve different video formats depending on the browser used? Should I use the "video" tag of HTML5 when I detect an HTML5 capable browser? What's the "safest" bet here? I take it that Flash is out of the equation seen that iPhone/iPad is a requirement.

• Is it possible to set a parameterized build or pass an environment variable via a hudson build trigger?

  - by Tim

  I'd like to use hudson to trigger a "promotion" of a build. The build would be a simple script that just copies a release candidate installer file from one location to another. (development dir to release/stable dir) Our build server is not on the public internet, but I want to be able to send an email or a text message or an IM with the build number to hudson, which will parse the build number and then do the copy/move. In looking at the jabber/IM plugin it does not look like this is possible (the parameter part) Has anyone solved this in some way? Should I use some other mechanism? I would prefer not to have to do the manual steps each time (SCP/FTP, etc) - I just want any QA team member to be able to trigger the build server to do the promotion.

• Dynamic form creation from XSD in ASP.NET

  - by CitadelCSAlum

  I know there is a lot of documentation on the internet as far as XSD to forms, but I have not been able to come across one that is straight forward enough for my situation. I am working with a WCF web service that is going to fetch and .xsd xml schema, and must return the HTML of a form based on the .xsd xml schema. Is there any third party tools that can help out with this, if so what are they? If not, do you have any suggestions,better methods,etc for how this can be done?

• PHP: Regular Expression to get a URL from a string

  - by Matthew Iselin

  I'm working on some PHP code which takes input from various sources and needs to find the URLs and save them somewhere. The kind of input that needs to be handled is as follows: http://www.youtube.com/watch?v=IY2j_GPIqRA Try google: http://google.com! (note exclamation mark is not part of the URL) Is http://somesite.com/ down for anyone else? Output: http://www.youtube.com/watch?v=IY2j_GPIqRA http://google.com http://somesite.com/ I've already borrowed one regular expression from the internet which works, but unfortunately wipes the query string out - not good! Any help putting together a regular expression, or perhaps another solution to this problem, would be appreciated.

• How to find with javascript if element exists in DOM or it's virtual (has been just created by creat

  - by user326574

  Hello. I hope a topic is self describing. I'm new on your site, it helped me much times but this time i was surprised not to find an answer on internet. The question is quite simple. Say, i have an element created in code: var elem = docuemnt.createElement('div'); ... I wish sometime to check have i placed it into the DOM before or it is still virtual. // check if elem is placed in the DOM (it's not) document.getElementByTagName('body')[0].appendChild(elem); // check - and it's finally in the document When use jquery i can write '$(elem).filter(':visible') or even $(elem).visible() if i remember correctly. But if it's based on the same javascript, then... All i want is to check does the element exist only virtually or it can be found in a document (and still may be not visible).

• String Encoding doesn't ouput all characters

  - by AndroidXTr3meN

  My client uses InputStreamReader/BufferedReader to fetch text from the Internet. However when I save the Text to a *.txt the text shows extra weird special symbols like 'Â'. I've tried Convert the String to ASCII but that mess upp å,ä,ö,Ø which I use. I've tried food = food.replace("Â", ""); and IndexOf(); But string won't find it. But it's there in HEX Editor. So summary: When I use text.setText(Android), the output looks fine with NO weird symbols, but when I save the text to *.txt I get about 4 of 'Â'. I do not want ASCII because I use other Non-ASCII character. The 'Â' is displayed as a Whitespace on my Android and in notepad. Thanks! Have A great Weekend! EDIT* found:   in Wordpad

• Why this button doesn't cause triple postback?

  - by focus

  We have developed a page with a asp.net and debugging it accidentally we have discovered on our page button with the next code on onclik attribute onclick="__doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton',''); __doPostBack('ctl00$FormPlace$m_userTaskMarkAsUnreadButton','');WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$FormPlace$m_userTaskMarkAsUnreadButton", "", true, "", "", false, false))" It seems that the button do three postbacks but when we click it only cause on postback. With this code seems that de button will cause three postbacks!! We have try it with Internet Explorer and Firefox and the button only cause on postback always. Are browsers who avoid that the button do three postback ? Or Is Asp.net server who avoid the three postback? We don't understand why the button behaves correctly if onclick attribute has three call to do Postbacks. Thanks

• How many databases to support eCommerce?

  - by Terry Lorber

  I have a system with two databases, one that the customer-facing website uses, the second that is used by the "backroom" order-fulfillment system. I've been asked to run queries from the website to the backroom system. I'd rather not, it seems risky to allow web-based request to run unheeded on the internal system. Additionally, this means opening up routing in the firewall to allow external connections to the internal server. What's the best practice for eCommerce? Run the entire company off of one database? Or individual databases for each system, and middleware to connect them? Sometimes it might be necessary for the web application to pull date from the internal system, but not based on an HTTP request from the internet. I'm sure the best answer is "it depends!" So, if people have a rule of thumb for when to use middleware and when not to, I'd like to here it.

I looked up on this over the Internet and found that i have to write a web service to expose the data from SQL server using ASP.NET. I did an app previously in android that would take data from my dropbox a/c and display it to the user. I made use of the drop-box api available. I was wondering if anything like that exists for SQL? Also, i have to code in Obj-C for the iPad, so how will i write ASP.NET code? I have more doubts. Thanks in advance.

• Access DB with SQL Server Back End

  - by uyuni99

  I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u
