  • executing perl code stored in a database?

    - by TheGNUGuy
    Hey everyone, Is it possible to save some perl code in a database then retrieve it using a select statement and then execute that perl code? I have tried using the eval() function but that doesn't seem to work. Here is what I'm trying right now and it doesn't seem to work: my $temp = $qryResults[0]; print $temp."\n"; eval{"$temp"}; the output is $con->Disconnect();exit; Thanks for the help!

    For a school project I am creating a simple search engine (using Struts2), where I read from a database, and redirect the user to a new page that shows the results. my struts.xml file is as follows: <action name="searchRooms" class="cz.vutbr.fit.Search" method="execute"> <result name="success">/pages/showSearchResults.jsp</result> <result name="input">/pages/search.jsp</result> </action> I have no idea what to search on Google to achieve this. I'm looking for a simple answer or some keywords to use for searching on Google.

  • Is there an SCM tool made for solo programmers with key logging built in?

    - by pokstad
    Are there any Source Code Management (SCM) tools made specifically for solo programmers or small groups of programmers that tracks every small change made to source code in real time? This would require all key strokes to be tracked, and any other small changes like GUI UI editing. This seems like it would be a very useful tool for a programmer trying to remember a fix he did an hour ago that they didn't manually commit.

  • Generating a reasonable ctags database for Boost

    - by Robert S. Barnes
    I'm running Ubuntu 8.04 and I ran the command: $ ctags -R --c++-kinds=+p --fields=+iaS --extra=+q -f ~/.vim/tags/stdlibcpp /usr/include/c++/4.2.4/ to generate a ctags database for the standard C++ library and STL ( libstdc++ ) on my system for use with the OmniCppComplete vim script. This gave me a very reasonable 4MB tags file which seems to work fairly well. However, when I ran the same command against the installed Boost headers: $ ctags -R --c++-kinds=+p --fields=+iaS --extra=+q -f ~/.vim/tags/boost /usr/include/boost/ I ended up with a 1.4 GB tags file! I haven't tried it yet, but that seems likes it's going to be too large to be useful. Is there a way to get a slimmer, more usable tags file for my installed Boost headers? Edit Just as a note, libstdc++ includes TR1, which has allot of Boost libs in it. So there must be something weird going on for libstdc++ to come out with a 4 MB tags file and Boost to end up with a 1.4 GB tags file.

  • Feeding a Drill Down Menu with categories, subcategories and subSubcategories from a database

    - by Hassan
    Hi everyone, I have a Drill Down menu and I want to have it gets its elements from a database, I am using php and MySQL and the table (categories) looks like this : http://yfrog.com/jctablehsj I can't figure out how I can extract these information in a way I could put it inside the Drill Down Menu ! I found the recursive method (with LEFT JOINs) and the nested method which I barely understood and again I couldn't apply it to the Drill Down Menu. I found that some people found out a solution with left join and group by but couldn't understand or copy their example ! I would be more than gratefull if you could give me the extact of the query. Thanks a lot for your hard work, Hassan

  • Convert BLOB to Jpg using C#

    - by TGuimond
    Hello, I am currently developing a web application that receives data from an on-site oracle database. The database developers have developed some web-services that I am able to call and send/receive data to and from the the database. When I want to display an image the method returns the image in BLOB format. My question is: what is the best way to convert BLOB to .jpg or .bmp so I can display the image correctly? If someone could point me in the right direction that would be great! Cheers, Tristan

  • How to check a SQL database table to see if a record exists

    - by Anthony
    I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists. I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made. Does that make sense? Using myConnectionCheck As New SqlConnection(myConnectionStringCheck) Dim myCommandCheck As New SqlCommand() myCommandCheck.Connection = myConnectionCheck myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName myConnectionCheck.Open() myCommandCheck.ExecuteNonQuery() End Using Thanks in advance, Anthony

  • ASP.NET MVC TDD with LINQ and SQL database

    - by dean nolan
    I am trying to start a new MVC project with tests and I thought the best way to go would have 2 databases. 1 for testing against and 1 for when I run the app and use it (also test really as it's not production yet). For the test database I was thinking of putting create table scripts and fill data scripts within the test setup method and then deleting all this in the tear down method. I am going to be using Linq to SQL though and I don't think that will allow me to do this? Will I have to just go the ADO route if I want to do it this way? Or should I just use a mock object and store data as an array or something?. Any tips on best practices? How did Jeff go about doing this for StackOveflow?

  • Drupal, mysql server settings

    - by Patrick
    hi, I've a problem to configure database settings in Drupal. I will propose here some sample data: Database Mysql: Database: databaseName User: user Password: password Server: server.com Server Choice: mysqldb2 (in phpmyadmin I have this option and I can choose between mysqldb1 and mysqldb2 to access to the mysql server) The error message I get is: The mysql error was: Access denied for user: 'user@localhost' (Using password: YES). I've tried the following lines in settings.php but I always get the same error message: $db_url = 'mysql://user:password@localhost/databaseName'; $db_url = 'mysql://user:password@localhost/databaseName/mysqldb2'; The user and password work in phpmyadmin so I'm sure they are correct. thanks

  • Computer Vision application(+web interface) for face detection and recognition from database

    - by Kush
    My project is a computer vision java application which should implement the following : A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application. Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV. Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face). Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition. I am well familiar with Java but the problem is that I need a guidance on how to organise it in a stepwise manner(links appreciated).OpenCv,Php and mySql are really messy.I know doing the openCV stuff within java is real overhead but i really want to do it.But If there is any suggestion to do it elseway please guide me.So any kind of help is a ray of hope for me. Thanks.

    I have downloaded and installed IE8. I was playing around with the debugger, but I could not figure out how to load external javascript files. It displays the javascript from the main page, but I need to debug the script in the external files. I have googled various articles that show a screenshot of an IE8 debugger with a drop-down for selecting which script to debug, but my debugger does not feature this. Can anyone help me with this? Thanks.

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!

  • Recommendation for web-based database visualization tool

    - by prometheus
    Tableau is extremely flexible when it comes to visualizing and playing around with datasets, but it is extremely slow when you go into "production mode" and publish a particular view that you've created onto your server. Does anyone know of any tools that can be used to connect to a database, present interactive (or somewhat interactive) dashboards, and perform reasonably well when published to a server? To be clearer, I am looking for something like this -- http://www.corda.com/executive-dashboard-graph-styles.php. I realize that such a product might not exist. If so, is there a particular framework or library that I could use to create killer interactive visualizations of data for the web?

  • Storing ASP.Net MVC Views in the Database

    - by Adam Albrecht
    For an ASP.Net MVC application, I'm interested in storing some views and/or partial views in the database so that a few semi-technical users can do some basic view logic. Does anyone have any tips or lessons from experience on doing this? I know Phil Haack wrote a blog post on this about a year ago. He used IronRuby for scripting his views, (which would be fine for me). He created a quick proof-of-concept, but I can't find any other information on the topic. Any ideas, thoughts, tips, etc would be appreciated. Thanks!

  • Creating a "less"-like console pager interface for pysqlite3 database

    - by Eric
    I would like to add some interactive capability to a python CLI application I've writen that stores data in a SQLite3 database. Currently, my app reads-in a certain type of file, parses and analyzes, puts the analysis data into the db, and spits the formatted records to stdout (which I generally pipe to a file). There are on-the-order-of a million records in this file. Ideally, I would like to eliminate that text file situation altogether and just loop after that "parse and analyze" part, displaying a screen's worth of records, and allowing the user to page through them and enter some commands that will edit the records. The backend part I know how to do. Can anyone suggest a good starting point for creating that pager frontend either directly in the console (like the pager "less"), through ncurses, or some other system?
