• Error while installing Microsoft SQL Server 2005 on Windows 7

  - by Brian Roisentul

  I was trying to install Microsoft SQL Server 2005 on my Windows 7 pc. When I tried to install it, it tells me that I have a newer version installed on my pc. So, I checked that Microsoft Sharepoint 2010 installed some sql server 2008 tools for me. I decided to uninstall SharePoint 2010(which I wasn't using) and then tried to install MS SQL Server 2005 again. This threw me the following exception: Error 1603 installing microsoft sql server setup support files Searching on Google I found this article: http://support.microsoft.com/kb/916760 but it's not my case actually. Any help will be appreciated. I really need this to continue working.

• Perl, efficient parsing of csv file

  - by Mike

  I'm working on a project that involves parsing a large csv formatted file in Perl and am looking to make things more efficient. My approach has been to split() the file by lines first, and then split() each line again by commas to get the fields. But this suboptimal since at least two passes on the data are required. (once to split by lines, then once again for each line). This is a very large file, so cutting processing in half would be a significant improvement to the entire application. My question is, what is the most time efficient means of parsing a large CSV file using only built in tools? note: Each line has a varying number of tokens, so we can't just ignore lines and split by commas only. Also we can assume fields will contain only alphanumeric ascii data (no special characters or other tricks). Also, i don't want to get into parallel processing, although that might work effectively.

• gwt typeahead missing

  - by arinte

  I have a GWT app with a bunch of textboxes. In firefox I would expect that when I type a word in a textbox that I have already typed in and submitted, that firefox would offer to autocomplete that text. But for this GWT app it is not happening. Also in IE it seems that none of my css stuff is loaded. And when I IE developer tools on my GWT page, it can focus in on any of the textboxes it just focuses on the encompassing DIV around all the textboxes.

• How to leverage Spring Integration in a real-world JMS distributed architecture?

  - by ngeek

  For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

• How can I find file system concurrency issues ?

  - by krosenvold

  I have an application running on Linux, and I find myself wanting windows (!). The problem is that every 1000 times or so I run into concurrency problems that are consistent with concurrent reading/writing of files. I am fairly sure that this behavior would be prohibited by file locking under Windows, but I don't have any sufficiently fast windows box to check. There is simply too much file access (too much data) to expect strace to work reliably - the sheer volume of output is likely to change the problem too. It also happens on different files every time. Ideally I would like to change/reconfigure the linux file system to be more restrictive (as in fail-fast) wrt concurrent access. Are there any tools/settings I can use to achieve this ?

• Programming and art

  - by user353874

  Specialized software does play a major role in every business field. Games provide new realities and are proved child development tools. Communication got a new meaning. Information never traveled so fast. And programming is never referred to as an art form. Why is that? Programming is not romantic and not natural so we don't feel naturally attached to it. Basically, our emotions don't fit programming. But it's really cool and better than art. :D

• WordPress > Activating plugin makes site go blank in one theme, not in another. Generated source ide

  - by Scott B

  Strangest thing. When I activate this specific plugin, the public side of the site goes blank (nothing but a white screen with blank view source). However, when I test the site with the wordpress default theme, the plugin does not conflict and the site works fine. The interesting thing is that I've compared the generated source (using FF's webmaster tools) with and without plugin activated and in each case they are identical. This led me to believe that perhaps the plugin was altering htaccess, however, that file is the same whether or not the plugin is active or not. How can I find out what is causing the problem with this plugin? The plugin is called "Crawl Rate Tracker".

• Django Photologue - use photo with original compression

  - by 123

  hi, I´m uploading photos with Django Photologue. Is it possible to leave the jpgs as the are? Even if I tell photosize to use Highest Quality compression the files end up having half as many kb as the originals. I must admit that the visable loss of quality is small but as i am a photographer i would like the images to apear exactly as i edited them (photoshop). I don´t need any of photosize´s cropping and effects tools. Can it be turned off completely? thanks for your answers.

• How do I combine an unmanaged dll and a managed assembly into one file?

  - by Lasse V. Karlsen

  SQLite from PHX Software has combined a managed assembly (System.Data.SQLite) with an unmanaged dll (the SQLite 32- or 64-bit dll) into one file, and managed to link them together. How do I do this? Do I need to embed the managed assembly into the unmanaged dll, or vice versa? ie. my questions are: In which order do I need to do this? What tools or knowledge do I need in order to do this? How (if different) do I link to the exported functions from the unmanaged dll in my managed code? The reason I ask this is that I want to build a managed zLib wrapper. I know there is managed classes in .NET but from experience they're a bit limited (and a bit boneheaded in that they don't do proper buffering), so I'd like to create my own copy, also because I want to learn how to do this. So does anyone know what I need to do and how?

• What is the most efficient way to find missing semicolons in VS with C++?

  - by Dr. Monkey

  What are the best strategies for finding that missing semicolon that's causing the error? Are there automated tools that might help. I'm currently using Visual Studio 2008, but general strategies for any environment would be interesting and more broadly useful. Background: Presently I have a particularly elusive missing semicolon (or brace) in a C++ program that is causing a C2143 error. My header file dependencies are fairly straightforward, but still I can't seem to find the problem. Rather than post my code and play Where's Wally (or Waldo, depending on where you're from) I thought it would be more useful to get some good strategies that can be applied in this and similar situations. As a side-question: the C2143 error is showing up in the first line of the first method declaration (i.e. the method's return type) in a .cpp file that includes only its associated .h file. Would anything other than semicolons or braces lead to this behaviour?

• Would Mercurial help me work from 2 PCs?

  - by rikh

  I currently use Perforce for source control, but want to start working on the code from 2 different PCs at the same time (desktop and laptop). The laptop would not be able to access the perforce server very often, which makes Perforce a poor choice in this setup. Distributed source control tools like Mercurial seem better suited to the task, but I am still not clear if this would work or not. Does anyone have any experience of using Mercurial to work on 2 machines at once (eg desktop in the week, laptop in evening and weekends). Does it help, or is it still a pain the butt keeping everything in sync and knowing what is going on.

• How do I read the cache of Chrome and Firefox programmatically on the Mac?

  - by John Gallagher

  Background I want to access the cache of Chrome and Firefox in my Cocoa application. I need to get the HTML for pages accessed recently. Safari is a piece of cake - all this information is available in SQLite data stores, but not so in Chrome and Firefox. The Problem For Firefox, the cache is in /Library/Caches/Firefox/Profiles/xxx.default/Cache with filenames _CACHE_001_ _CACHE_002_ _CACHE_003_ and _CACHE_MAP_ For Chrome, the cache is in /Library/Caches/Google/Chrome/Default/Cache with filenames data_0 data_1 data_2 and data_3 What I've tried The only article I can find that sheds any light on what format these caches are in is here. It recommends a Cache Viewer tool, but doesn't explain how one might do this programmatically. Questions Is there any way of reconstructing this data using command line tools or the Cocoa framework? Or is it much too low level? Is there another way of getting at the HTML of recent web pages that I don't know about?

• Resources for TDD aimed at Python Web Development

  - by Null Route

  I am a hacker not and not a full-time programmer but am looking to start my own full application development experiment. I apologize if I am missing something easy here. I am looking for recommendations for books, articles, sites, etc for learning more about test driven development specifically compatible with or aimed at Python web application programming. I understand that Python has built-in tools to assist. What would be the best way to learn about these outside of RTFM? I have searched on StackOverflow and found the Kent Beck's and David Astels book on the subject. I have also bookmarked the Wikipedia article as it has many of these types of resources. Are there any particular ones you would recommend for this language/application?

• Many to Many DataSet Insert to Database using Stored Procedures

  - by Jonn

  I'm trying to do a many-to-many bulk insert to the database using a list of three different types of models. The only tools I can use are stored procedures and datasets. (But I can't use DataSet fills or DataAdapters, just plain ol' Stored Procedures). Is there an easy way to pass multiple values, let alone, pass three different lists and bulk insert them to a table in the database using stored procedures? (As specified in the title, the three tables are actually two tables and a third table to establish the many-to-many relationship between the two.)

• MySQL dual license behavior

  - by jromero

  Hi SO, I'm running a commercial(closed source) Web App development for the first time. Initially I considered MySQL the most feasible option for a DB, until I get quite confused about its dual license behavior. If I want a commercial application do I still can use the GPL version of MySQL or I must get a license? The same question in a different way: If I use MySQL's GPL version does that force me to license the whole app under GPL? Either case I would go with PostgreSQL, I just want to make really really sure about this. Even in SO I've seen related("duplicates") questions but never a clear answer... All other tools I'm gonna use to code the project are licensed under BSD or MIT. Just in case, the role of MySQL in the project is merely as relational DB to store persistent data and query it. I'd really appreciate if someone can clarify this for me. Regards, thanks in advanced.

• If you could unlearn everything you know, and start again

  - by Rob Conery

  I'm giving a presentation at NDC 2010 and in one of the talks I'm going to focus on education and its power over your career (and you personally). There are people who mercilessly educate themselves, and there are others who are a bit ho-hum about it, feeling a bit of apathy. If you remove all of the risk associated surrounding a "refocus" of your career - what choices would you make? What things would you learn and what would you do with it? Think of it as a reroll, Ground Hog day, starting over from scratch today. What platform and language choices would you make and why? Most important to me are those who are completely happy where they are - would love to hear more about what it is that keeps you where you're at. Please do let me know what platform and tools you work with - it would help tremendously! Thanks in advance.

• Memory Warning but Small Live Bytes

  - by Kamchatka

  Hi everyone, In my application, I get a memory warning of level 1 and then 2 after repeating some action (choosing a picture + processing) several times and then a crash. The leak tool doesn't show any leak. I'm also following the Allocations tool in Instruments and my Live Bytes are roughly 4 MB, overall I allocate 113 MB. At maximum I have maybe 20 MB in memory when the picture is loaded. Since I have to repeat an action to get to the crash, it is very likely to be a memory leak. However, I don't know how to locate it since my live bytes are 4 MB and things supposed to be allocated (apart a small leak of ~100 KB in the UIImagePickerController). How much can I trust the memory leak/allocation tools? Would you have an advice to help me locate the reason of the problem?

• Struts/JSP/J2EE performance and memory profiling and issues

  - by Berlin Brown

  We are using Struts and having performance issues. And making heavy use of jsp includes, tiles, EL expressions. I am sure this is eating up a lot of memory and processing time. What are some approaches to profile the JSP page? What tools could I use? What should I look for when profiling? I have seen the code generated JSP Java Servlet Code and I see the bottlenecks but would rather measure it more accurately. This is under JDK1.5 and IBM Websphere 6.1 (RAD7)

• BeautifulSoup: Get the contents of a specific table

  - by Adam Matan

  Hi, My local airport disgracefully blocks users without IE, and looks awful. I want to write a Python scripts that would get the contents of the Arrival and Departures pages every few minutes, and show them in a more readable manner. My tools of choice are mechanize for cheating the site to believe I use IE, and BeautifulSoup for parsing page to get the flights data table. Quite honestly, I got lost in the BeautifulSoup documentation, and can't understand how to get the table (whose title I know) from the entire document, and how to get a list of rows from that table. Any ideas? Adam

• How do you go from an abstract project description to actual code?

  - by Jason

  Maybe its because I've been coding around two semesters now, but the major stumbling block that I'm having at this point is converting the professor's project description and requirements to actual code. Since I'm currently in Algorithms 101, I basically do a bottom-up process, starting with a blank whiteboard and draw out the object and method interactions, then translate that into classes and code. But now the prof has tossed interfaces and abstract classes into the mix. Intellectually, I can recognize how they work, but am stubbing my toes figuring out how to use these new tools with the current project (simulating a web server). In my professors own words, mapping the abstract description to Java code is the real trick. So what steps are best used to go from English (or whatever your language is) to computer code? How do you decide where and when to create an interface, or use an abstract class?

• Visual Studio Add-in - How do I create an Installer?

  - by Morgeh

  I have made a Visual Studio Add-in as part of a project I'm working on using web services. When I created the new Add-in project in visual studio it generated all the code required and installed the blank add-in on my pc (I assume). Since this is a large project we are using svn to manage the code base and once I had done some of the work on the Add-in I commited it, then checked it out on a different pc and attempted to run it. However on the other pc when I run the add-in in debug mode, the tools entry for the add-in is not present and I can't run the add-in. Am I right in assuming that when I created the project on the other pc it installed the plugin aswell?? and does that mean that I will need to create an installer for any other pcs I wish to use? Obviously at some point I intend on making an installer anyway but not untill after the development of the addin is complete.

• What online brokers offer APIs?

  - by Wilco

  So I'm getting really sick of E*TRADE and, being a developer, would love to find an online broker that offers an API. It would be great to be able to write my own trading tools, and maybe even modify existing ones. Based on my research so far, I've only found one option. Interactive Brokers offers a multi-language API (Java/C++/ActiveX/DDE) and has some fairly decent commission rates to boot. I want to make sure there aren't any other options out there I should be considering. Any ideas? Update: Based on answers so far, here's a quick list...

• Override asbolute position on child container (modal window)

  I have a modal window that is pulled from the server and inserted into a container that is absolute positioned. When that window is triggered to open, it does not display properly, it positions itself inside the container and most of it is hidden. Is there a specific css to be written for the container of the modal window (MyModalWindow). My code is as follows: <div style="position:relative;"> <div style="position: absolute;"> <div id="MyModalWindow"> </div> </div> </div> This is a jquery tools window.
