• Advice for last year college graduates

  - by Tomh

  Hey guys, I know there are many "advice" questions around this site. But I wanted to to narrow mine down to last year college students, in my case my last year as Master student in computer science. So far is a list of things I've done during my time in college (which I can recommend others to do aswell): Code a lot I've written several hobby projects, had part time jobs, entered the Imagine cup from Microsoft, took programming extensive courses and did freelance gigs. Read a lot I've bought most top books from the recommended book topics here, to be honest I have not read them all. learn different languages I've tried several languages including Haskell, Java, Python, Ruby, Lisp, Prolog, C#, PHP, JS, AS3 and possibly some more I forgot. Tried to start a blog Joel recommends to learn how to write, I tried starting a couple of blogs to improve upon this, I gave up on all instances after writing about three posts. It was just not my thing... Have a portfolio of launched projects/programs I'm busy with this, have a couple of finished, working projects I worked on to show to people. So this is my last year. Is there anything else you can recommend a last year college student to do before hitting the job market? Personally I'm tempted to spend my time on the following: Practice algorithm design Learn and memorize the usage of the low level API's of your favorite language Polish your portfolio Why? Because those first two will make sure you pass the majority of the interviews, here in Holland (I could be wrong). I rather not spend my time on those first two points, but I have to be realistic and thats just my experience on what kind of questions you'll get when you apply. The third point is my hope that I won't have to answer questions about the amount of standard types in c# for example if they can see I get projects done and launched. But I'm still graduating, so I don't know anything :), and many of you might be hiring grads on a recent base and could tell me and other interested people what you wish that the recent grads you interviewed would have done before they applied.

• PHP4 including file during session

  - by Matherw

  I am trying to put second language on my webpage. I decided to use different files for different languages told apart by path - language/pl/projects.ln contains Polish text, language/en/projects.ln - English. Those extensions are just to tell language files from other, the content is simple php: $lang["desc"]["fabrics"]["title"] = "MATERIALY"; $lang["desc"]["fabrics"]["short_text"] = "Jakis tam tekst na temat materialów"; $lang["desc"]["services"]["title"] = "USLUGI"; $lang["desc"]["services"]["short_text"] = "Jakis tam tekst na temat uslóg"; And then on the index page I use it like so: session_start(); if (isset($_SESSION["lang"])) { $language = $_SESSION["lang"]; } else { $language = "pl"; } include_once("language/$language/projects.ln"); print $lang["desc"]["fabrics"]["title"]; The problem is that if the session variable is not set everything works fine and array item content is displayed but once I change and set $_SESSION["lang"] nothing is displayed. I tested if the include itself works as it should by putting print "sth"; at the beginning of projects.ln file and that works all right both with $_SESSION["lang"] set and unset. Please help.

• How does Visual Studio's source control integration work with Perforce?

  - by Weeble

  We're using Perforce and Visual Studio. Whenever we create a branch, some projects will not be bound to source control unless we use "Open from Source Control", but other projects work regardless. From my investigations, I know some of the things involved: In our .csproj files, there are these settings: <SccProjectName <SccLocalPath <SccAuxPath <SccProvider Sometimes they are all set to "SAK", sometimes not. It seems things are more likely to work if these say "SAK". In our .sln file, there are settings for many of the projects: SccLocalPath# SccProjectFilePathRelativizedFromConnection# SccProjectUniqueName# (The # is a number that identifies each project.) SccLocalPath is a path relative to the solution file. Often it is ".", sometimes it is the folder that the project is in, and sometimes it is ".." or "..\..", and it seems to be bad for it to point to a folder above the solution folder. The relativized one is a path from that folder to the project file. It will be missing entirely if SccLocalPath points to the project's folder. If the SccLocalPath has ".." in it, this path might include folder names that are not the same between branches, which I think causes problems. So, to finally get to the specifics I'd like to know: What happens when you do "Change source control" and bind projects? How does Visual Studio decide what to put in the project and solution files? What happens when you do "Open from source control"? What's this "connection" folder that SccLocalPath and SccProjectFilePathRelativizedFromConnection refer to? How does Visual Studio/Perforce pick it? Is there some recommended way to make the source control bindings continue to work even when you create a new branch of the solution?

• How do you build a Windows Workflow Project with NAnt 0.90?

  - by LockeCJ

  I'm trying to build a Windows Workflow (WF) project using NAnt, but it doesn;t seem to be able to build the ".xoml" and ".rules" files. Here is the code of the csc task that I'm using: <csc debug="${build.Debug}" warninglevel="${build.WarningLevel}" target="library" output="${path::combine(build.OutputDir,assembly.Name+'.dll')}" verbose="${build.Verbose}" doc="${path::combine(build.OutputDir,assembly.Name+'.xml')}"> <sources basedir="${assembly.BaseDir}"> <include name="**/*.cs" /> <include name="**/*.xoml" /> <include name="**/*.rules" /> </sources> <resources basedir="${assembly.BaseDir}"> <include name="**/*.xsd" /> <include name="**/*.resx" /> </resources> <references> ... </references> </csc> Here's the output: Compiling 21 files to 'c:\Output\MyWorkFlowProject.dll'.

• Visual Studio Debugging is not attaching to WebDev.WebServer.EXE

  - by Aaron Daniels

  I have a solution with many projects. On Debug, I have three web projects that I want to start up on their own Cassini ASP.NET Web Development servers. In the Solution Properties - Common Properties - Startup Project, I have Multiple startup projects chosen with the three web applications' Action set to Start. All three web development servers start, and all three web pages load. However, Visual Studio is only attaching to two of the WebDev.WebServer.EXE processes. I have to manually go attach to the third process in order to debug it with the debugger. This behavior just started happening, and I'm at a loss as to how to troubleshoot this. Any help is appreciated. EDIT: Also to note, I have stopped and restarted the development servers several times with no change in behavior. Also, when attaching to the process manually, I see that the Type property of the two automatically attached WebDev.WebServer.EXE processes is Managed, while the Type property of the unattached WebDev.WebServer.EXE process is TSQL, Managed, x86. When looking at the project's properties, however, I am targeting AnyCPU, and do NOT have SQL Server debugging enabled. EDIT: Also to note, the two projects that attach correctly are C# web applications. <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids> The project that is not attaching correctly is a VB.NET web application. <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids> EDIT: Also to note, the behavior is the same on another workstation. So odds are that it's not a machine specific problem.

• Resolving MSBuild 4.0 warnings

  - by Hadi Eskandari

  I've upgraded a solution to use MSBuild 4.0. It compiles but I get lots of warnings, for example: "T:\projects\Castle.Core\buildscripts\Build.proj" (Package target) (1) - "T:\projects\Castle.Core\Castle.Core-vs2008.sln" (Build target) (2:2) - "T:\projects\Castle.Core\src\Castle.DynamicProxy.Tests\Castle.DynamicProxy.Tests-vs2008.csproj" (default target) (3:2) - D:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(847,9): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.0.30319" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend. [T:\projects\Castle.Core\src\Castle.DynamicProxy.Tests\Castle.DynamicProxy.Tests-vs2008.csproj] How can I fix these warnings? It is related to .NET 4.0 Multitargeting pack or SDK, but there's no SDK for .NET 4.0 AFAIK and Multi-Target pack can not be installed separatly. Any ideas would be appreciated.

• jQuery cycle plugin customizing

  - by spirax

  I'm using the jQuery Cycle plugin to start a slidshow of images when hovering over the initial image. This works fine. What I want after that is to have the slideshow stop when hovered off, and have a manual slideshow (next/prev buttons) start. This currently works, but the slideshow starts from the beginning each time it's initialized. I want it to begin at the current image that's loaded. I was playing around with getting the image's index from the DOM (as it's the only one with display:block) and using the option 'startingSlide' to resume it, but my index keeps returning as -1. jQuery('#home-menu li').hover(function() { setImages(jQuery(this).attr('title'), jQuery(this).find('.subtitle').text()); jQuery('#main .blog #projects .gallery .slideshow').cycle( { fx: 'scrollHorz', easing: 'easeOutBounce', speed: 2000, delay: 0 }); }, function() { // Before loading the images for the clickable slideshow, find the current image in the DOM array to use as the starting position slideshowStart = jQuery('.gallery .slideshow img:visible').index(this); console.log('Index: ' + slideshowStart); setImages(jQuery(this).attr('title'), jQuery(this).find('.subtitle').text()); jQuery('#main .blog #projects .gallery .slideshow').cycle('stop').cycle( { fx: 'scrollHorz', easing: 'easeOutBounce', startingSlide: slideshowStart, speed: 2000, timeout: 0, next: "#main .blog #projects .gallery span.span2", prev: "#main .blog #projects .gallery span.span1" }); }); setImages() just loads images into the DOM based on what li is being hovered over. Nothing special there. I want the image to be resumed when hovered over and hovered off. I've left out the resume part for hover on for the moment while I was trying to get it working - In case you were wondering.

• ASP, sorting database with conditions using multiple columns...

  - by Mitch

  First of all, I'm still working in classic ASP (vbScript) with an MS Access Database. And, yes I know its archaic, but I'm still hopeful I can do this! So now to my problem: Take the following table as an example: PROJECTS ContactName StartDate EndDate Complete Mitch 2009-02-13 2011-04-23 No Eric 2006-10-01 2008-11-15 Yes Mike 2007-05-04 2009-03-30 Yes Kyle 2009-03-07 2012-07-08 No Using ASP (with VBScript), and an MS Access Database as the backend, I’d like to be able to sort this table with the following logic: I would like to sort this table by date, however, depending on whether a given project is complete or not I would like it to use either the “StartDate” or “EndDate” as the reference for a particular row. So to break it down further, this is what I’m hoping to achieve: For PROJECTS where Complete = “Yes”, reference “EndDate” for the purpose of sorting. For PROJECTS where Complete = “No”, reference “StartDate” for the purpose of sorting. So, if I were to sort the above table following these rules, the output would be: PROJECTS ContactName StartDate EndDate Complete 1 Eric 2006-10-01 2008-11-15* Yes 2 Mitch 2009-02-13* 2011-04-23 No 3 Kyle 2009-03-07* 2012-07-08 No 4 Mike 2007-05-04 2009-03-30* Yes *I’ve put a star next to the date that should be used for the sort in the table above. NOTE: This is actually a simplified version of what I really need to do, but I think that if I could just figure this out, I’ll be able to do the rest on my own. ANY HELP IS GREATLY APPRECIATED; I’VE BEEN STRUGGLING WITH THIS FOR FAR TOO LONG NOW! Thank you!

• How to best implement Version Control for Web Development?

  - by Adam Taylor

  Version control systems are obviously important in development projects but there use in web development projects appears to be more complex, what with the requirement of having a web server to run all but the simplest of web applications. With that in mind, I have looked around and discovered a few different methods of using version control in web development projects: Provide each developer with a virtual machine which is a replication of the development server and have the developer run their working copy of the application in the virtual machine. Have each developer use a sub domain on the development server, e.g. john.project.com and checkout their working copy of the app to the directories the sub domain points to. Use the version control system to checkout code, make a change, commit the code and then check it on the development server (which points to the head of the repository). I can see a drawback of 1 being the added time required to create the virtual machines and ensure that the virtual machines are kept insync with the development server (also the need(?) to continuously change the developers host file to point at the virtual machine not the development server). I can see 2 possibly being a problem if absolute URLs are used within the site unless there is an easy way to update the configuration to use the new subdomains as well. 3 is the easiest to set up but is rather primitive and it will presumably become quite tedious for a developer to keep checking in the code after every time change. How have the users of stackoverflow used version control with web development projects and which method/workflow was most effective. Please also include extra methods I haven't thought of / read about.

• Can't get MySQL source query to work using Python mysqldb module

  - by Chris

  I have the following lines of code: sql = "source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql" cursor.execute (sql) When I execute my program, I get the following error: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'source C:\My Dropbox\workspace\projects\hosted_inv\create_site_db.sql' at line 1 Now I can copy and past the following into mysql as a query: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql And it works perfect. When I check the query log for the query executed by my script, it shows that my query was the following: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql However, when I manually paste it in and execute, the entire create_site_db.sql gets expanded in the query log and it shows all the sql queries in that file. Am I missing something here on how mysqldb does queries? Am I running into a limitation. My goal is to run a sql script to create the schema structure, but I don't want to have to call mysql in a shell process to source the sql file. Any thoughts? Thanks!

• Namespaces combined with TFS / Source Control explanation

  - by Christian

  As an ISV company we slowly run into the "structure your code"-issue. We mainly develop using Visual Studio 2008 and 2010 RC. Languages c# and vb.net. We have our own Team Foundation Server and of course we use Source Control. When we started developing based on the .NET Framework, we also begun using Namespaces in a primitive way. With the time we 'became more mature', i mean we learned to use the namespaces and we structured the code more and more, but only in the solution scope. Now we have about 100 different projects and solutions in our Source Safe. We realized that many of our own classes are coded very redundant, i mean, a Write2Log, GetExtensionFromFilename or similar Function can be found between one and 20 times in all these projects and solutions. So my idea is: Creating one single kind of root folder in Source Control and start an own namespace-hierarchy-structure below this root, let's name it CompanyName. A Write2Log class would then be found in CompanyName.System.Logging. Whenever we create a new solution or project and we need a log function, we will 'namespace' that solution and place it accordingly somewhere below the CompanyName root folder. To have the logging functionality we then import (add) the existing project to the solution. Those 20+ projects/solutions with the write2log class can then be maintained in one single place. To my questions: - is that a good idea, the philosophy of namespaces and source control? - There must be a good book explaining the Namespaces combined with Source Control, yes? any hints/directions/tips? - how do you manage your 50+ projects?

• Managing common components with Fossil CVS

  - by Larry Lustig

  I'm a Fossil (and CVS configuration novice) attempting to create and manage a set of distributed Fossil repositories for a Delphi project. I have the following directory tree: Projects Some Project Delphi Components LookupListView Some Client Some Project For Client Some Other Project For Client Source Code Project Resources Project Database I am setting up Fossil version control in order to version and share Projects\Some Client\Some Other Project For Client\Source Code, which contains Delphi 2010 source for a database project. This project makes use of Projects\Delphi Components\LookupListView which is a Delphi component. I need this code to be included in the versioning system for my project. I will, in theory, need to include it in other Fossil repositories in the future, as well. If I create my Fossil repository at the Source Code or Some Other Project For Client level, I cannot add any code above that level to my repository. What is the proper way to deal with this? The two solutions that occur to me are 1) Creating a separate repository for LookupListView and make sure that everyone who uses a repository for a project that references it "knows" that they must also get the current version of this project as well. This seems to defeat the purpose of being able to obtain a complete, current version of the project with a single checkout. The problem is magnified because there are other common component dependencies in this project. 2) Establishing my Fossil repository in the Projects directory, so I can check in files from various subfolders. This seems to me to involve an awful lot of extra path-typing when doing adds, and also to impose my directory structure (Some Client\Some Other Project For Client\Source) on the other users of the repository -- in this case, the actual client. Any suggestions appreciated.

• NHibernate.MappingException - Troubles Shooting Checklist (no persister for)

  - by Berryl

  Here's a starter list: 1) if hbm is hand generated, is it an embedded resource? 2) if using FNH, does it pass a PerssistenceSpecification test? 3) if not using FNH, can you save and then load the persisted class? 4) more? I'm sure many of you have gotten this one at one point or another. But have you ever gotten it when you knew your mapping was set up correctly? I started getting this exception after I started using a new repository design, but only in one scenario! PersistenceSpecification tests pass, as do all repository methods (using SQLite). The scenario that leads to the exception is when legacy projects from a different db are converted to green field system. The legacy system is from a different database and has it's own session factory, which should be irrelevant because the error comes after previously unconverted Projects are retrieved and in memory. As the routine tries to save these unconverted Projects into the new database, the exception is thrown, full stack trace below. Any ideas on how to build up the trouble shooting check list and solves this problem? Cheers, Berryl === the Exception trace ===== failed: NHibernate.MappingException : No persister for: Smack.ConstructionAdmin.Domain.Model.Projects.Project at NHibernate.Impl.SessionFactoryImpl.GetEntityPersister(String entityName) at NHibernate.Impl.SessionImpl.GetEntityPersister(String entityName, Object obj) at NHibernate.Engine.ForeignKeys.IsTransient(String entityName, Object entity, Nullable`1 assumed, ISessionImplementor session) at NHibernate.Event.Default.AbstractSaveEventListener.GetEntityState(Object entity, String entityName, EntityEntry entry, ISessionImplementor source) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.PerformSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.OnSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.FireSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.SaveOrUpdate(Object obj) NHibernate\Repository\FabioNHibRepository.cs(46,0): at Smack.Core.Data.NHibernate.Repository.FabioNHibRepository`1.Add(T item) LegacyConversion\LegacyBatchUpdater.cs(20,0): at Smack.ConstructionAdmin.Data.LegacyConversion.LegacyBatchUpdater.ConvertOpenLegacyProjects(ILegacyProjectDao legacyProjectDao, IProjectRepository greenProjectRepository) Data\Brownfield\ProjectBatchUpdate_SQLiteTests.cs(19,0): at Smack.ConstructionAdmin.Tests.Data.Brownfield.ProjectBatchUpdate_SQLiteTests.Test()

• Generating a static website from a set of content data (possibly with webgen, webby or a similar too

  - by Darel

  My company (an engineering firm) is looking to redesign their website with some dynamic content. We have a nice portfolio of projects that we'd like to present on our site by category. To elaborate, I'd like to have a "Projects Category" menu, where you can choose a sub-project category (such as churches, schools, etc) which links to a page with images of all projects which have been tagged with that category attribute. Clicking on an image would then take you to a detailed page for that project. I have done a good bit of asp and jsp page development, but I've always worked on the front end in an enterprise environment - I've never built a production site from the back end. The advice I've gotten so far is that a full-blown CMS solution would be somewhat overkill, as we won't have a large hit count, and we'll be displaying a few hundred projects at most. One big-picture choice I appear to have - whether to dynamically generate the pages (with asp or jsp) or to use a tool to generate a set of static html pages. The tool would build the menus, project summary pages, and individual project pages based on a set of data I could provide (in the form of a database or text file.) I'm leaning towards trying to use a tool like webgen or webby to statically generate the site due to our current web hosting situation. Any thoughts on which approach is more appropriate? Is webgen or webby capable of doing what I am trying to do? Or can anyone recommend other web authoring tools better equipped to accomplish this? Thanks for any feedback!

• Merging: hg/git vs. svn

  - by stmax

  I often read that hg (and git and...) are better at merging than svn but I have never seen practical examples of where hg/git can merge something where svn fails (or where svn needs manual intervention). Could you post a few step-by-step lists of branch/modify/commit/...-operations that show where svn would fail while hg/git happily moves on? Practical, not highly exceptional cases please... Some background: we have a few dozen developers working on projects using svn, with each project (or group of similar projects) in its own repo. We know how to apply release- and feature-branches so we don't run into problems very often (i.e. we've been there, but we've learned to overcome joel's problems of "one programmer causing trauma to the whole team" or "needing six developers for two weeks to reintegrate a branch"). We have release-branches that are very stable and only used to apply bugfixes. We have trunks that should be stable enough to be able to create a release within one week. And we have feature-branches that single developers or groups of developers can work on. Yes, they are deleted after reintegration so they don't clutter up the repository. ;) So I'm still trying to find the advantages of hg/git over svn. I'd love to get some hands-on experience, but there aren't any bigger projects we could move to hg/git yet, so I'm stuck with playing with small artifical projects that only contain a few made up files. And I'm looking for a few cases where you can feel the impressive power of hg/git, since so far I have often read about them but failed to find them myself.

• Internal bug tracking tickets - Redmine, Trac, or JIRA

  - by Tai Squared

  I've been looking at setting up Redmine, Trac, or JIRA to track issues. I want to be able to have my development team create internal tickets that are never seen by clients, while clients can create/edit tickets that are seen by the internal team. From the Trac documentation, you can set permissions to create or view tickets, but it doesn't seem to allow for viewing only certain tickets. It may be possible with Trac Fine Grained Permissions, but doesn't appear so. The Redmine documentation mentions: Define your own roles and set their permissions in a click but doesn't appear to have the level of granularity. From the JIRA documentation: At the moment JIRA is only able to support security at a project level or issue level. Currently there is no field level security available. According to this question, Redmine doesn't support internal tickets, so you would have to use multiple projects. I don't want a situation where I would have to create multiple projects - one internal, one external and have the external tickets brought into the internal repository. It seems as this would lead to unnecessary overhead and inevitably, the projects wouldn't be in sync. Is there any way with any of these products (possibly through a plug-in if not in the core product itself) to specify these permissions, or simplify having two projects with different users and permissions that must still share information?

• Split large repo into multiple subrepos and preserve history (Mercurial)

  - by Andrew

  We have a large base of code that contains several shared projects, solution files, etc in one directory in SVN. We're migrating to Mercurial. I would like to take this opportunity to reorganize our code into several repositories to make cloning for branching have less overhead. I've already successfully converted our repo from SVN to Mercurial while preserving history. My question: how do I break all the different projects into separate repositories while preserving their history? Here is an example of what our single repository (OurPlatform) currently looks like: /OurPlatform ---- Core ---- Core.Tests ---- Database ---- Database.Tests ---- CMS ---- CMS.Tests ---- Product1.Domain ---- Product1.Stresstester ---- Product1.Web ---- Product1.Web.Tests ---- Product2.Domain ---- Product2.Stresstester ---- Product2.Web ---- Product2.Web.Tests ==== Product1.sln ==== Product2.sln All of those are folders containing VS Projects except for the solution files. Product1.sln and Product2.sln both reference all of the other projects. Ideally, I'd like to take each of those folders, and turn them into separate Hg repos, and also add new repos for each project (they would act as parent repos). Then, If someone was going to work on Product1, they would clone the Product1 repo, which contained Product1.sln and subrepo references to ReferenceAssemblies, Core, Core.Tests, Database, Database.Tests, CMS, and CMS.Tests. So, it's easy to do this by just hg init'ing in the project directories. But can it be done while preserving history? Or is there a better way to arrange this?

• Enter ID instead of name on submit (form)

  - by Derek

  In my activities table, I have a user ID and a project ID. When a user (of admin level) creates an activity they select from a drop down menu a project. Here is the select query to draw up appropriate values: $sql = "SELECT usersprojects_tb.projectid, projects.projectname FROM projects INNER JOIN usersprojects on projects.projectid = usersprojects.projectid WHERE usersprojects.userid = '".$_SESSION['SESS_USERID']."'"; And for the tag with the dropdown menu, I have this: <?php echo $row['projectname']?> I have tried submitting the form with 'projectid' here instead and the project ID is stored successfully in my activies table. However, the user needs to see the project names (IDs arent exactly user-friendly!) And with 'projectname' as displayed, they can select the names of the available projects (to associate an activity with) but the project ID is not stored, how I link this up, so that when the project name is sent, the ID for this project is stored properly in my activities table. I'm also having the exact same problem with the users drop down. As the admin user selects a user from the drop down to assign the task to. I exactly what I want, but I think I may be using the wrong syntax! Any help is much appreciated. Thanks.

• How should I design my MYSQL table/s?

  I built a really basic php/mysql site for an architect that uses one 'projects' table. The website showcases various projects that he has worked on. Each project contained one piece of text and one series of images. Original projects table (create syntax): CREATE TABLE `projects` ( `project_id` int(11) NOT NULL auto_increment, `project_name` text, `project_text` text, `image_filenames` text, `image_folder` text, `project_pdf` text, PRIMARY KEY (`project_id`) ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=latin1; The client now requires the following, and I'm not sure how to handle the expansions in my DB. My suspicion is that I will need an additional table. Each project now have 'pages'. Pages either contain... One image One "piece" of text One image and one piece of text. Each page could use one of three layouts. As each project does not currently have more than 4 pieces of text (a very risky assumption) I have expanded the original table to accommodate everything. New projects table attempt (create syntax): CREATE TABLE `projects` ( `project_id` int(11) NOT NULL AUTO_INCREMENT, `project_name` text, `project_pdf` text, `project_image_folder` text, `project_img_filenames` text, `pages_with_text` text, `pages_without_img` text, `pages_layout_type` text, `pages_title` text, `page_text_a` text, `page_text_b` text, `page_text_c` text, `page_text_d` text, PRIMARY KEY (`project_id`) ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=latin1; In trying to learn more about MYSQL table structuring I have just read an intro to normalization and A Simple Guide to Five Normal Forms in Relational Database Theory. I'm going to keep reading! Thanks in advance

• Permissions on Mac OSX

  - by Linda

  I think that this is a permissions issue but I am not sure and I am not sure how to repair the problem. I have a new MacBook. I have 2 external drives that were previously used on another MacBook. I have a lot of folders and XCode projects on the external drives. When I try to work on the projects, there is a message similar to this: "This file is not writable. You may not be able to save your changes, but you will be able to Save a Copy somewhere else. Do you want to edit this file anyway?" If I make changes and try to close the project I get this error: "The project and user files project.pbxproj and macbook.pbxuser for project “thirdtry.xcodeproj” are not writeable and cannot be saved. Your changes will be lost if you close the project. You may need to SCM edit these files to gain writability." I have tried just to rename the folder but that permission is not allowed either unless I individually change permissions for every file in an XCode project. As you can imagine, this could be time consuming for tons of files and projects. I can copy the project into internal memory and can run it then after renaming the folder that contains all of the files. This defeats the purpose of having all of the projects on an external drive. Also, in XCode, there is no "Build and Run" there is only "Build and Debug" now. I don't know if this is related or not. Suggestions for how to repair all permissions to all files and folders on my external drives? What about the "Build and Debug" and no "Build and Run" choice? Thanks, Linda

• Gacutil.exe successfully adds assembly, but assembly missing from GAC. Why?

  - by Ben McCormack

  I'm running GacUtil.exe from within Visual Studio Command Prompt 2010 to register a dll (CatalogPromotion.dll) to the GAC. After running the utility, it says Assembly Successfully added to the cache, and running gacutil /l CatalogPromotionDll shows that the GAC contains the assembly, but I can't see the assembly when I navigate to C:\WINDOWS\assembly from Windows Explorer. Why can't I see the assembly in WINDOWS\assembly from Windows Explorer but I can see it using gacutil.exe? Background: Here's what I typed into the command prompt for VS Tools: C:\_Dev Projects\VS Projects\bmccormack\CatalogPromotion\CatalogPromotionDll\bin \Debuggacutil /i CatalogPromotionDll.dll Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved. Assembly successfully added to the cache C:\_Dev Projects\VS Projects\bmccormack\CatalogPromotion\CatalogPromotionDll\bin \Debuggacutil /l CatalogPromotionDll Microsoft (R) .NET Global Assembly Cache Utility.

The Global Assembly Cache contains the following assemblies: CatalogPromotionDll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=9188a175 f199de4a, processorArchitecture=MSIL Number of items = 1 However, the assembly doesn't show up in C:\WINDOWS\assembly.

• Adding an ADO.NET Entity Data Model throws build errors

  - by user3726262

  I am using Visual Studio 2013 express. I create a new project and then I add a database to that project. But, when I add an ADO.NET Entity Framework model to that project and then run the program, I get the following four build errors listed below. To try to remedy this myself, I added the namespaces 'System.Data.Entity' and 'System.Data.Entity.Design', but that didn't help. Also, I uninstalled and re-installed the Nuget package. I also uninstalled and re-installed Visual Studio 2013 Express for Windows Desktop. But these measures didn't help the situation either. Please note that I used to use the Entity Data model just fine. But it was around the time that I did a system restore on my computer, and when I updated VS 2013 with an update offered on the start page, and finally, when I signed up for MS Azure, that I started running into the problem described above. Now I would think that uninstalling and reinstalling Visual Studio 2013, and then installing the 'Nuget' Package would solve all problems. What am I missing here? The errors mentioned above are: Error 1 The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity' (are you missing an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 14 30 DataLayer Error 2 The type or namespace name 'DbContext' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 16 52 DataLayer Error 3 The type or namespace name 'DbModelBuilder' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 23 49 DataLayer Error 4 The type or namespace name 'DbSet' could not be found (are you missing a using directive or an assembly reference?) C:\Users\John\documents\visual studio 2013\Projects\Riches\Riches\RichesModel.Context.cs 28 16 DataLayer Thank you and I realize that my last attempt at this question was rather rough-draftish, John

• Problem with relative file path

  - by Richard Knop

  So here is my program, which works ok: import java.io.FileReader; import java.io.BufferedReader; import java.io.IOException; import java.util.Scanner; import java.util.Locale; public class ScanSum { public static void main(String[] args) throws IOException { Scanner s = null; double sum = 0; try { s = new Scanner(new BufferedReader(new FileReader("D:/java-projects/HelloWorld/bin/usnumbers.txt"))); s.useLocale(Locale.US); while (s.hasNext()) { if (s.hasNextDouble()) { sum += s.nextDouble(); } else { s.next(); } } } finally { s.close(); } System.out.println(sum); } } As you can see, I am using absolute path to the file I am reading from: s = new Scanner(new BufferedReader(new FileReader("D:/java-projects/HelloWorld/bin/usnumbers.txt"))); The problem arises when I try to use the relative path: s = new Scanner(new BufferedReader(new FileReader("usnumbers.txt"))); I get an error: Exception in thread "main" java.lang.NullPointerException at ScanSum.main(ScanSum.java:24) The file usnumbers.txt is in the same directory as the ScanSum.class file: D:/java-projects/HelloWorld/bin/ScanSum.class D:/java-projects/HelloWorld/bin/usnumbers.txt How could I solve this?

• Python, Ruby, and C#: Use cases?

  - by thaorius

  Hi everyone. For as long as I can remember, I've always had a "favorite" language, which I use for most projects, until, for some particular reason, there is no way/point on using it for project XYZ. At that point, I find myself rusty (and sometimes outdated) on other languages+libraries+toolchains. So I decided, I would just use some languages/libs/tools for some things, and some for other, effectively keeping them fresh (there would obviously be exceptions, I'm not looking for an arbitrary rule set, but some guidelines). I wanted an opinion on what would be your standard use cases (new projects) for Python, Ruby, and C# (Mono). At the moment, I have time like this:Languages: C#: Mid-Large Sized Projects (mainly server-side daemons) High Performance (I hardly ever need C's performance, but Python just doesn't cut it) Relatively Low Footprint (vs the JVM, for example) Ruby: Web Applications Python: General Use Scripts (automation, system config, etc) Small-Mid Sized Projects Prototyping Web Applications About Ruby, I have no idea what to use it for that I can't use Python for (specially considering Python is more easily found installed by default). And I like both languages (though I'm really new to Ruby), which makes things even worse. As for C#, I have not used a Windows powered computer in a few years, I don't make things for Windows computers, and I don't mind waiting for Mono to implement some new features. That being said, I haven't found many people on the internet using it for server-sided *nix programming (not web related). I would appreciate some insight on this too. Thanks for your time.
