• Database table copying

  - by vbNewbie

  I am trying to rectify a previous database creation with tables that contains data that needs to be saved. Instead of recreating a completely new database since some of the tables are still reusable, I need to split a table that exists into 2 new tables which I have done. Now I am trying to insert the data into the 2 new tables and because of duplicate data in the old table I am having a hard time doing this. Old table structure: ClientProjects clientId PK clientName clientProj hashkey MD5 (clientname and clientProj) new table structures: client clientId PK clientName projects queryId PK clientId PK projectName I hope this makes sense. The problem is that in the old table for example you have clients with multiple clientIds.

• how to use a pear package!?

  - by Naughty.Coder

  I want to use HTTP_DOWNLOAD to manage my downloads ,, I have never used PEAR before !! HTTP_DOWNLOAD depends on many other packages , I downloaded them and the ones they , in turn , depend on and this is the structure I made : Download.PHP <---HTTP_DOWNLOAD MAIN FILE Header.php <--- HTTP_HEADER MAIN FILE PEAR.php PEAR5.php Type.php <--- MIME_Type >Type <---- FOLDER - Extension.php MIME_Type File - Parameter.php MIME_Type File assuming that Http_DOWNLOAD depends on : * PHP 4.2.0 * PEAR 1.4.0b1 * PEAR * HTTP_Header * pcre extension * Archive_Tar (Optional) * Archive_Zip (Optional) * MIME_Type (Optional) * mime_magic extension (Optional) * pgsql extension (Optional) and I edited the paths inside each file to reflect this structure , and I tried to run the following code : <?php require_once 'Download.php'; $params = array('file'=>'file.zip'); $down = new HTTP_Download($params); $down->send(true); ?> nothing happens !!

• how to iterate over non-English file names in PHP

  - by Sabya

  I have a directory which contains several files, many of which has non-english name. I am using PHP in Windows 7. I want to list the filename and their content using PHP. Currently I am using DirectoryIterator and file_get_contents. This works for English files names but not for non-English (chinese) file names. For example, I have filenames like "?? ?? ?????????.eml", "hello ??????.eml". DirectoryIterator is not able to get the filename using ->getFilename() file_get_contents is also not able to open even if I hard code the filename in its parameter. How can I do it?

• tomcat 6 - Cluster / BackupManager

  - by Kevin

  Hi, I have a question regarding Clustering (session replication/failover) in tomcat 6 using BackupManager. Reason I chose BackupManager, is because it replicates the session to only one other server. I am going to run through the example below to try and explain my question. I have 6 nodes setup in a tomcat 6 cluster with BackupManager. The front end is one Apache server using mod_jk with sticky session enabled Each node has 1 session each. node1 has a session from client1 node2 has a session from client2 .. .. Now lets say node1 goes down ; assuming node2 is the backup, node2 now has two sessions (for client2 and client1) The next time client1 makes a request, what exactly happens ? Does Apache "know" that node1 is down and does it send the request directly to node2 ? =OR= does it try each of the 6 instances and find out the hard way who the backup is ?

• Loop over a file and write the next line if a condition is met

  - by 111078384259264152964

  Having a hard time fixing this or finding any good hints about it. I'm trying to loop over one file, modify each line slightly, and then loop over a different file. If the line in the second file starts with the line from the first then the following line in the second file should be written to a third file. !/usr/bin/env python with open('ids.txt', 'rU') as f: with open('seqres.txt', 'rU') as g: for id in f: id=id.lower()[0:4]+'_'+id[4] with open(id + '.fasta', 'w') as h: for line in g: if line.startswith(''+ id): h.write(g.next()) All the correct files appear, but they are empty. Yes, I am sure the if has true cases. :-) "seqres.txt" has lines with an ID number in a certain format, each followed by a line with data. The "ids.txt" has lines with the ID numbers of interest in a different format. I want each line of data with an interesting ID number in its own file. Thanks a million to anyone with a little advice!

• Google app engine or Amazin ec2 for Restful services and direct access to datastore

  - by imran

  I'm thinking of building a Restful app on either App engine or ec2 devloped in Java. I'm interested in opinions/experience of using the two options for this. The primary purpose is to create web services to write and retrieve data through a mobile device...basically creating an API for the service I want to create. It seems to me it would be quicker and cheaper in the beginning to go with google app engine using either restlet or grails.But I also think that I could run into problems in the future when I want to so somthing more advanced and might be restricted by app engines environment. I also want to be able to do data analysis on the data in the datastore as well. It seems that with app engine this would be hard as I don't have direct access to the datastore ( in Amazon I could still have access to the underlying db if I go with MySQL ) .

• Generating short license keys with OpenSSL

  - by Marc Charbonneau

  I'm working on a new licensing scheme for my software, based on OpenSSL public / private key encryption. My past approach, based on this article, was to use a large private key size and encrypt an SHA1 hashed string, which I sent to the customer as a license file (the base64 encoded hash is about a paragraph in length). I know someone could still easily crack my application, but it prevented someone from making a key generator, which I think would hurt more in the long run. For various reasons I want to move away from license files and simply email a 16 character base32 string the customer can type into the application. Even using small private keys (which I understand are trivial to crack), it's hard to get the encrypted hash this small. Would there be any benefit to using the same strategy to generated an encrypted hash, but simply using the first 16 characters as a license key? If not, is there a better alternative that will create keys in the format I want?

• Django Comments and Users integration

  - by Patrick

  Hi folks, I am new to django. I am trying to use django.contrib.comments, I saw the table in the database like this, but how can I integrate it with user_id, user_photos, user_name, user_email....and those things with the django commenting system? I also tried to use thread-comments, but I can't configure it properly, is the django threadedcomments table similar to following ? Please let me know if any of you have done this before....all I need is a user login, and post comments, and then show list of comments with users' profile photos and username, as well as there comments. I think shouldn't be that hard.

• Where does C# and the .NET Framework fail?

  - by Nate Bross

  In my non-programming life, I always attempt to use the approprite tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, powershell, batch files, and Java, as well as being versed in the web technologes (javascript, html/css). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. The bottom line here, is that I feel that I'm choosing C# and .NET simply because I am very comfertable with it, so I'm looking for cases where you have chosen something other than .NET, even though you are primarly a .NET developer.

• How can I get Dashcode to open JSP files?

  - by user332000

  A simple tools question but it's driving me nuts. I have some .jsp files on my computer that I associated with Dashcode, figuring it would be a suitable editor. But when I try to open the files, all I get is a dialog box that says, "Dashcode cannot open files of this type". I thought there'd be an easy way to fix this but I can't find it. Nowhere in Dashcode's preferences can I find any list of valid file extensions. I poked around its resources folder for a while and couldn't find it there either. The Dashcode menubar is visible when the error is up, so I'm guessing that this is Dashcode itself complaining that it cannot open this file rather than the OS preventing it from trying. How exactly does this work? Is Dashcode really just hard-coded to recognize only files of certain types by their file extension? Isn't there a way to change it? Thanks, Frank

• onclick event not working after ie7 reload

  - by Charles

  I am using Javascript to dynamically create part of my page content. A routine that generates a set of img tags is called from the window.onload event. Those img tags are assigned attributes, including an onclick event. The img tags host thumbnail images that, when clicked, change the src property of the image in the main view div. Everything works properly in FF 3.5. I can reload the page and the dynamically generated onclick events continue to fire as expected. In IE7 everything works normally until I reload the page. At that point events that were hard coded into the xhtml section continue to work as expected, and the dynamically generated img tags are shown on the page, but their onclick events fail to work. How can I get IE7 to implement the dynamically generated click events on reload?

• Making change recursively: How do I modify my algorithm to print all combinations?

  - by cb

  I have an algorithm that recursively makes change in the following manner: public static int makeChange(int amount, int currentCoin) { //if amount = zero, we are at the bottom of a successful recursion if (amount == 0){ //return 1 to add this successful solution return 1; //check to see if we went too far }else if(amount < 0){ //don't count this try if we went too far return 0; //if we have exhausted our list of coin values }else if(currentCoin < 0){ return 0; }else{ int firstWay = makeChange(amount, currentCoin-1); int secondWay = makeChange(amount - availableCoins[currentCoin], currentCoin); return firstWay + secondWay; } } However, I'd like to add the capability to store or print each combination as they successfully return. I'm having a bit of a hard time wrapping my head around how to do this. The original algorithm was pretty easy, but now I am frustrated. Any suggestions? CB

• nHibernate query looking for the related object's related object

  - by code-zoop

  I have an nHibernate querie issue that looks quite straight forward, but I can't seem to get my head around it! I am creating some simple example classes to illustrate my problem: public class Car { public int Id { get; set; } public IList<Interior> InteriorParts { get; set; } } public class Interior { public int Id { get; set; } public InteriorProducer Producer { get; set; } } public class InteriorProducer { public int Id { get; set; } } Now to the query: I have the id of the InteriorProducer, but need to get a list of Cars where the interior have been produced by the interior producer. So in a simple, pseudo SQL, it looks something like this: select cars where car.InteriorParts.Producer.Id = Id I have a really hard time getting my head around this to create an nHibernate query. Any Ideas? Thanks

• documenting black-box test cases

  - by Blux

  Hi everyone, I want to write an initial (black box) test cases for one of my university projects. I haven't started coding yet, I'm still in completing the SRS document and i should specify the test cases i'm going to implement after the coding. The project is web based, and i should follow this template in each test case: +++++ Test case ID: Author: Initial state: Preconditions: Use Case: Test input: Expected output: ++++++ The thing is, i don't know what is the difference between "initial state" and "preconditions". In some of the test cases it's hard to differentiate between them. Like in "Edit Page" what should be the initial state and what should be the preconditions? any help will appreciated.=)

• Free (as in beer) Reverse Image Search API/Library/Service

  - by Bauer

  TinEye provides a great way to "reverse" search by image (i.e. upload/transload an image and have multiple possible sources of that image returned as results.) Since screen-scraping is messy and unreliable, I'm looking for a free API/library/web-service that could offer the same (or similar) reverse-image search function. At present, TinEye offers a commercial API, but since I'll only be using the service for small personal projects, it's hard to justify the cost of the service (the lowest being 1,000 searches for $70 USD). Is anyone aware of such a free service? Or is there a simpler way to approach this (programmatic solution; any language)? I understand that this is a tall order, and submitting the question is really only a last resort in the hope that there is some solution. Example image search is 99designs' StackOverflow logo competition entry by wolv

• PHP protected classes and properties, protected from whom?

  - by Andrew Heath

  I'm just getting started with OOP PHP via PHP Object-Oriented Solutions and am a little curious about the notion of protection in OOP. The author clearly explains how protection works, but the bit about not wanting others to be able to change properties falls a bit flat. I'm having a hard time imagining a situation where it is ever possible to prevent others from altering your classes, since they could just open up your class.php and manually tweak whatever they pleased seeing as how PHP is always in plaintext. Caution: all of the above written by a beginner with a beginner's understanding of programming...

• PHP4 No Error When Missing Method is Called

  - by INTPnerd

  I have come across an annoying problem while writing some PHP4 code. I renamed the method of a class but I forgot to rename it where it was being called from. The annoying part is it was hard to track down where the problem was because no error was triggered. The script simply aborted leaving the web page partially rendered. Is it normal for this not to trigger an error or is there something wacky going on here? If this is normal is there a way to force this kind of thing to cause an error?

• Android : Hello, Views > Google Map View Tuorial

  - by Tom

  Hi, I'm trying to complete the Android MapView tutorial @ www.developer.android.com/resources/tutorials/views/hello-mapview.html I think I've done the entire thing correctly but I'm getting an error message in Eclipse. I'm sure why. The problematic line of code is private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); I'm relatively new to Java but I've gone through the forums of different things and I really have no idea on this one. I've [attached][2] a screen shot of the development environment - hopefully it wont be anything too obvious or hard to fix either! http://lh5.ggpht.com/_sqCs2rXr5hQ/S-CJf4x9ZUI/AAAAAAAAAHI/IR-kTcOnfU8/s144/hellogooglemaps.jpg Cheers Tom :)

• How would I access the Windows Login (Authentication) API from a C++ Service Application?

  - by Gabriel

  Let us imagine for a moment that I have a piece of hardware that can act as an authentication for a user on a given system. I want to write an application in C++ to run as a service, look for this device and if found log the appropriate user in. I believe I have found the API's I would need to use to perform the hardware and service portions of the application but am having a hard time nailing down a way to create a "real" user login. Is this possible? If so where would I look to find resources on accomplishing this? I think of it as being an analog to fingerprint scanner login type devices.

• Visual Studio debugger problem

  - by Alexandre Pepin

  In Visual Studio 2008, after debugging about 1-2 minutes, when I press F10 (Step Over), the debugger hangs and Visual Studio freezes for 5-10 seconds and then go to the next line. Then whatever I do (F10, F5, F11, etc), the debugger continues the execution as if i pressed F5 and all my forms that I was debugging close. I always have to restart the application. It is very hard to reproduce and it does not occurs every time I want to debug something. Does anyone has a solution ?

• Need help getting Suspend to work in Ubuntu on laptop

  - by Aerik

  I've been doing a lot of research, but I've got to admit right out front that I'm not even sure exactly what is the right question. I've installed Kubuntu 10.4 on a Panasonic Toughbook CF-29. When I try to uses "suspend", the screen flickers, and then the hard drive light goes off but the power light stays on. I looked at the /var/log/pm-suspend.log, but I don't seen any errors... though I'm not sure what success should look like either. So I guess my real question is a bit more accurately stated as "How do I troubleshoot suspend not working in Kubuntu on a laptop?" Thanks, Aerik

• What is the best solution to do Reporting on Object data for .NET ?

  - by Peter Fox

  Hi, Our projects are using objects as the data source to reports. Our business layer is returning single objects or IEnumerable. Our reports (quite complex) need to display value-type properties of the object, and its related objects. Typical case would be, from a List, display a master report with category data, then a subreport with data for each Product inside each Category, then a subreport for each Part of each Product, and so on. Reporting from the database is not an option for us. We have tried so far - Reporting Services : works but have to mess around with the XML definition of the report to define the datasource classes, very hard to work with if you use an object datasource, architecturally not too clean - Telerik Reports : quite nice (esp., nice architecture) but seems to have problems with complex reports (master/sub), does not give great paging control, rumored to have performance/crash problems (immature product). Does anyone know a good reporting solution that can be integrated in an ASP.NET application and works well with objects as datasources ?

• MySQl - update field by counting data in other table

  - by Qiao

  There are two tables. One is users info "users", one is comments info "comments". I need to create new field "comments" in users table, that contains number of comments of that user. Table "comments" has "user" field with user's id of that comment. What is optimal way to count number of comments by every user? With php you should write script that selects every user and than count number of his comments and then update "comments" field. It is not hard for me, but boring. Is it possible to do it without php, only in MySQL?
