• Losing sessions with window.open and cakephp redirection in PHP with cakephp

  - by vsecades

  Hi guys, Ok, here goes a very strange problem... Our team is using cakephp to develop a large application. Everything session related is working properly so far. The only issues we've had so far are related to iframes and opening windows in other subdomains. I'll explain: User opens up site A and logs into it, creation a User in a session. Cookies are set, everything works as expected. The user clicks a link that opens up Site B via Javascript. When they go to that site, they are automatically logged in by a backend mechanism and infrastructure. Site B is a subdomain of Site A. On that site there is another mechanism to go back to the first page (a link rather) that logs them back in to site A. The fun part about this whole process is the following, and that on step 3, when we click on the link, the session on Site A has been lost. I know it's lost because it is forcing login again. I am a bit lost, as the rest of the application that work with AJAX and uses iframes and stuff works flawlessly, just this one item does not work as one would expect. Any assistance would be appreciated. Cheers, Valentin

• "Error generating Win32 resource" in Visual Studio, Windows 7 x64

  - by Jerad Rose

  My co-developers and I recently upgraded machines to Windows 7 Ultimate 64 bit. Some of us are seeing a new error we used to never see when building solutions in Visual Studio (happens in both 2008 and 2010): Error generating Win32 resource: The process cannot access the file because it is being used by another process. It always points to some temp file in our output folder, for example: MyProject\obj\Debug\CSC5123.tmp This happens about once every four or so builds. We then will try to run the same exact build again, and it will usually succeed. In some cases though, it will fail again on the same project, and in same cases, it will fail on a different project. There's really no rhyme or reason to it. But it's very frustrating, especially when it doesn't happen until the build has been running for 20 or so seconds. This also doesn't happen to all of our coworkers. It happens to about one out of four developers. For the one, it happens about one of four builds, and for the other three, it never happens. Oh, and did I mention we're all using machines built from the same image? :) Thanks in advance for any direction you can provide.

• Getting MSDeploy working on our build/integration server - Is an MSBuild upgrade necessary?

  - by Jeff D

  We have what I think is a fairly standard build process: 1. Developer: Check in code 2. Build: Polls repo, sees change, and kicks off build that: 3. Build: Updates from repo, Builds w/ MSBuild, Runs unit tests w/ nunit, 4. Build: creates installer package Our security team allows us to pull from the build server, but does not allow the build server to push. So we generally rdp in, d/l the installers, and run them, which rules out the slick deployment services, so I would need to generate packages instead. I'd like to use MSDeploy, except that we have the following issues: We're on .net 3.5, and the MSBuild target (Package) that uses MSDeploy requires 4.0. Is there anything I'd need to install other than .net 4.0 RC for this? (Would MSBuild be part of that upgrade?) When I generate packages with MSDeploy, I see that I don't have just 1 file. There's a zip, deploy.cmd, SourceManifest.xml, and SetParameters.xml. What are all the other files for, and why wouldn't they all be in the 'package'? It sounds as if you can create packages by telling the system to look at a working IIS site. But if the packages are build from a CI environment, aren't you basically out of luck here? It feels like they designed some of this for small-scale developers deploying from their dev environment. That's a fine use case, but I'm interested in see what everyone's enterprise-experience is with the tool Any suggestions?

• Can aptitude for learning Programming paradigms be influenced by culture or native language's gramma

  - by DVK

  It is well known that different people have different aptitudes regarding various programming paradigms (e.g. some people have trouble learning non-procedural, especially functional languages. Some people have trouble understanding pointers - see Joel Spolsky's blog for musings on that. Some people have trouble grasping recursion). I was recently reading about a study that looked at how the grammar of someone's native language affected their speed of learning math. Can't find that article now but a quick googling found this reference. That led me to wondering whether someone's native culture or first language might affect their aptitude towards various programming paradigms. I'm more curious about positive influences - e.g. some trait that make it easier/faster for someone to learn a particular paradigm, for example native language grammar being very recursion-oriented. To be clear, I'm looking for how culture/language grammare may affect the difference between aptitude of the same person towards various paradigms as opposed to how it affects overall aptitude towards programming between different persons. Important: the only answers I'm interested in are either references to scientific studies, or personal observations from someone intimately familiar with a particular culture/language, including from their own experience. E.g. I'm not interested in your opinion of how Chinese being your first language affects anything unless you speak Chinese or worked with extremely large set of Chinese-native programmers extensively. I'm OK with your guesstimates not based on scientific studies, but please be sure to supply your reasoning about plausible causes of your observation. I'm not interested in culture-bashing (any such commends will be deleted or flagged for deletion). I'm also not particularly interested in culture-building - we all know Linus is from Finland and Tetris was written in Russia and Larry Wall is an American. Any culture/nation can produce a brilliant mind in any discipline. I'm interested in averages.

• Mac gcc non-virtual thunk error

  - by fret

  I'm getting these non-virtual thunk errors only in the Deployment build of my app. It uses a private framework called Lgi. Building on 10.5.8 using XCode 3.1.4 (latest for leopard?) The error looks like this: Ld /Users/matthew/Code/Scribe-Branches/v2.00/build/Development/Scribe.app/Contents/MacOS/Scribe normal i386 cd /Users/matthew/Code/Scribe-Branches/v2.00 /Developer/usr/bin/g++-4.0 -arch i386 -L/Users/matthew/Code/Scribe-Branches/v2.00/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/build/Development -F/Users/matthew/Code/Lgi/build -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Deployment -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Deployment -filelist /Users/matthew/Code/Scribe-Branches/v2.00/build/Scribe.build/Development/Scribe.build/Objects-normal/i386/Scribe.LinkFileList -framework Carbon -framework Lgi -o /Users/matthew/Code/Scribe-Branches/v2.00/build/Development/Scribe.app/Contents/MacOS/Scribe Undefined symbols: "non-virtual thunk to GWindow::OnDrop(char*, GVariant*, GdcPt2, int)", referenced from: vtable for ScribeWndin ScribeApp.o vtable for GShutdownin ScribeApp.o vtable for CalendarUiin Calendar.o vtable for CalendarViewWndin CalendarView.o vtable for CalendarConfigin CalendarView.o vtable for ScribeExportin Exp_Scribe.o vtable for GNewMailDlgin GNewMailDlg.o ....etc for lots of classes.... Anyway I know I'm not leaving those undefined because it does in fact link and run fine in the development build. Now after googling the issue the first thing to try is changing the optimization setting, which I did... and no dice. Some link error. So these virtual functions are initially defined in GDragDropTarget, and GWindow's inheritance looks like this: class LgiClass GWindow : public GView #ifndef WIN32 , public GDragDropTarget #endif (LgiClass being for __declspec export/import on win32) Any ideas on what to try next? Maybe I need to provide more info.

• TextBlock Wrapping in WPF Layout

  - by Joel Martinez

  Hi, I'm trying to figure out how to do something similar to the twitter silverlight app that Scott Guthrie demoed recently in WPF: http://weblogs.asp.net/scottgu/archive/2010/03/18/building-a-windows-phone-7-twitter-application-using-silverlight.aspx Unfortunately, I seem to be having a hard time understanding the wpf layout system in some fundamental way. I've been trying various combinations of horizontalalignment/stretch, width/auto at different levels in the hierarchy, and I can't seem to get the "message" textblock to wrap without assigning an explicit width. All I want is for the text to wrap based on the width of the window (or whatever is the parent container). <Window x:Class="TweeterWin.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <ScrollViewer Height="auto" > <ListBox Name="tweetList" Height="auto" > <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="132"> <Image Source="{Binding Avatar}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/> <StackPanel > <TextBlock Text="{Binding User}" TextWrapping="Wrap" Foreground="#FFC8AB14" FontSize="15" /> <TextBlock Text="{Binding Message}" TextWrapping="Wrap" FontSize="10" /> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </ScrollViewer> </Window> As a follow up, if anyone can send any links my way that might help me understand some of these layout fundamentals. I think I understand the main layout options (canvas, grid, stackpanel, etc.), but I dont' understand why I can't get this textblock to wrap in this scenario. Thanks!

• Installing python-mysql with wamp's mysql

  - by sharat87

  Hello, (I'm not sure if this should be asked here or SU.. but seeing this question on SO, I am asking it here...) I have wamp (mysql-5.1.33) server setup on my vista machine, and I am trying to install python-mysql 1.2.3c1 to use the mysql version provided by wamp. At first, when I ran python setup.py install, I got an error saying it couldn't find the location of the mysql's bin folder. Looking into setup_windows.py, I noticed it was looking for a registry key and so I added that registry entry and I think it is able to find it now. But now, when I run python setup.py install, I get a different error saying Unable to find vcvarsall.bat. Any help on installing this appreciated. Here is the output of python setup.py install: running install running bdist_egg running egg_info writing MySQL_python.egg-info\PKG-INFO writing top-level names to MySQL_python.egg-info\top_level.txt writing dependency_links to MySQL_python.egg-info\dependency_links.txt reading manifest file 'MySQL_python.egg-info\SOURCES.txt' reading manifest template 'MANIFEST.in' writing manifest file 'MySQL_python.egg-info\SOURCES.txt' installing library code to build\bdist.win32\egg running install_lib running build_py copying MySQLdb\release.py -> build\lib.win32-2.6\MySQLdb running build_ext building '_mysql' extension error: Unable to find vcvarsall.bat Thanks a lot!

• Adding visible "Markers" to represent Geopoints to a MapView using ItemizedOverlay in Android

  - by LordSnoutimus

  Hello, I am building an application which stores GPS locations in a SQLite database and then outputs the data onto a MapView using an Overlay by drawing a red line between the points. I want to be able to show graphical markers (images) for each of these points as well as the red line. My code is as follows: public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { populate(); points.addElement(point); } //public void setProjection(Projection projection) { // this.projection = projection; // } public void draw(Canvas canvas, MapView view, boolean shadow) { populate(); int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } } What would be the easiest way to implement adding markers for each GeoPoint?

• Linq-To-Objects group by

  - by Oskar Kjellin

  Hey, I'm building a software for timereporting I have a Dictionary<string, Dictionary<string, double>>. The key in the main dictionary is a users name and their value is a dictionary of . I have a function GetDepartment(string UserName) which returns a string with the users department. What I want is to crate a new dictionary, of the same type, that has the department as the main key and in the subdictionary a where hours is the total for that department. I have been trying to do this with linq but did not succeed. Would be very glad for some help here! EDIT: This code does exactly what I want. But I want it in LINQ Dictionary<string, Dictionary<string, double>> temphours = new Dictionary<string, Dictionary<string, double>>(); ; foreach (var user in hours) { string department = GetDepartment(user.Key); if (!temphours.ContainsKey(department)) { temphours.Add(department, new Dictionary<string, double>()); } foreach (var customerReport in user.Value) { if (!temphours[department].ContainsKey(customerReport.Key)) { temphours[department].Add(customerReport.Key, 0); } temphours[department][customerReport.Key] += customerReport.Value; } }

• Ideas for OpenSource CMS in ASP.NET MVC

  - by rajesh pillai

  I am in the process of collecting ideas for building an opensource CMS based on ASP.net framework. I have choosen ASP.NET MVC with Jquery as the tool to develop this. I have made this as community wiki. Background: Most of the good CMS that is available is built on PHP, though off late CMS built on ASP.net framework seems to be cropping up. I would like to collect ideas/suggestion/expectations from an opensource CMS system for ASP.net platform. I am looking for expectation from technology and features that you wish could find in a modern CMS and any other thoughts/ideas that comes to your mind. Your input would be of great help in this direction. Meanwhile I am also reviewing many opensource CMS system built on ASP.net as well as MS Office Sharepoint to get ideas and I would update my findings here for your reference. The following are some of the opensource CMS/BlogEngines that I am in the process of reviewing. -Oxite (ASP.net MVC) : This is the new kid on the block -Wordpress -BlogEngine.net -Umbraco Some of the features that I can think of is noted below Simplified content creation Support Multiple content author Metadata feature Workflow engine Simplified deployment List based contents (sharepoint like) Customizable URL's Support content Caching Roles (contenauthor, contentpublisher etc) Support different types of content (like html, txt, document, image, videos) Skinnable (support extensible themes) Localization & Globalization Unlimited nesting of categories Readymade template for blog, forums,survey. Good documentation You can add your points or add some depth to any of the above feature.

• Version control of software refactoring

  - by Muhammad Alkarouri

  What is the best way of doing version control of large scale refactoring? My typical style of programming (actually of writing documents as well) is getting something out as quickly as possible and then refactoring it. Typically, refactoring takes place at the same time as adding other functionality. In addition to standard refactoring of classes and functions, functions may move from one file to another, files get split and merged or just reordered. For the time being, I am using version control as a lone user, so there is no issue of interaction with other developers at this stage. Still, version control gives me two aspects: Backup and ability to revert to a good version "in case". Looking at the history tells me how the project progressed and the flow of ideas. I am using mercurial on windows using TortoiseHg which enables selections of hunks to commit. The reason I mention this is that I would like advice on the granularity of a commit in refactoring. Should I split refactoring from functionality added always in committing? I have looked at the answers of http://stackoverflow.com/questions/68459/refactoring-and-source-control-how-to but it doesn't answer my question. That question focuses on collaboration with a team. This one concentrates on having a history that is understandable in future (assuming I don't rewrite history as some VCS seem to allow).

• NetBeans generates JpaController with errors

  - by Xorty

  Hi, I am using NetBeans 6.8 for building Spring MVC application. Techonologies : Spring MVC 2.5 Derby DB Hibernate for ORM GlassFish v3 server I use New JPA Controller Classes from Entity Classes for adding ORM file. It is supposed to generate class for managing queries with my POJO files. Problem is, that NetBeans generates following code, and won't compile : public int getBrandCount() { EntityManager em = getEntityManager(); try { CriteriaQuery cq = em.getCriteriaBuilder().createQuery(); Root<Brand> rt = cq.from(Brand.class); cq.select(em.getCriteriaBuilder().count(rt)); Query q = em.createQuery(cq); return ((Long) q.getSingleResult()).intValue(); } finally { em.close(); } } At the picture, there is NetBeans error : It looks like method getCriteriaBuilder of Entity Manager Interface is unimplemented. Or some other reason why I can't use it in code. I don't know what other info should I provide, so please ask if anything comes to your mind. Thanks

• How to write a Media Center plugin like the Netflix plugin? Source code/reference samples?

  - by Vin

  I am looking to write a Windows Media Center plugin just like the Netflix WMC plugin. Once logged in, I know the streaming urls that I need to hook in to. Any source code, reference samples would be great. Found one on codeplex for swedish TV channels, but right now it's not working for some reason... Previously asked the following question, with no answers, so updated with a question asked in a easy to relate fashion Host a streaming video in my client, from a streaming url that is behind a login session? I am building a Silverlight 4 desktop client to show streaming video from a site that is login based. So that website has a Silverlight player that does streaming video, the player is behind a login sesion, so just by getting the url from fiddler and trying to play it in my Silverlight 4 desktop client won't work. Actually after that, I want to build a Windows Media Center plugin to build a Netflix-like client, that allows login through WMC and then allows you to watch streaming video. Any pointers on how to go about doing any of this?

• What's a good way to teach my son to program Java

  - by Software Monkey

  OK, so I've read through various posts about teaching beginner's to program, and there were some helpful things I will look at more closely. But what I want to know is whether there are any effective tools out there to teach a kid Java specifically? I want to teach him Java specifically because (a) with my strong background in C I feel that's too complex, (b) Java is the other language I know extremely well and therefore I can assist meaningfully without needing to teach myself a new but (to me) useless language, and (c) I feel that managed languages are the future, and lastly (d) Java is one of the simplest of all the languages I know well (aside from basic). I learned in basic, and I am open to teaching that first, but I am unaware of a decent free basic shell for Windows (though I haven't really searched, yet since it's not my first choice), and would anyway want to progress quickly to Java. My son is 8, so that's a couple of years earlier than I started - but he has expressed an interest in learning to program (possibly because I work from home a lot and he sees me programming all the time). If no-one can suggest a tool designed for this purpose, I will probably start him off with text/console based apps to teach the basics, and then progress to GUI building. Oh, one last thing, I am not a fan of IDE's (old school text editor type), so I would not be put off at all by a system that has him typing real code, and would likely prefer that to a toy drag/drop system. EDIT: Just to clarify; I really am specifically after ways to teach him Java; there are already a good many posts with good answers for other language alternatives - but that's not what I am looking for here. EDIT: What about Java frameworks for 2D video games - can anyone recommend any of them from personal experience? I like the idea of him starting with the mechanics in place (main game loop, scoring, etc) and adding the specifics for a game of his own imagining - that's what I did, though for me it was basic on a Commodore VIC-20 and a Sinclair ZX-81.

• Best way to escape characters before jquery post ASP.NET MVC

  - by Darcy

  Hello, I am semi-new to ASP.NET MVC. I am building an app that is used internally for my company. The scenario is this: There are two Html.Listbox's. One has all database information, and the other is initally empty. The user would add items from the database listbox to the empty listbox. Every time the user adds a command, I call a js function that calls an ActionResult "AddCommand" in my EditController. In the controller, the selected items that are added are saved to another database table. Here is the code (this gets called every time an item is added): function Add(listbox) { ... //skipping initializing code for berevity var url = "/Edit/AddCommand/" + cmd; $.post(url); } So the problem occurs when the 'cmd' is an item that has a '/', ':', '%', '?', etc (some kind of special character) So what I'm wondering is, what's the best way to escape these characters? Right now I'm checking the database's listbox item's text, and rebuilding the string, then in the Controller, I'm taking that built string and turning it back into its original state. So for example, if the item they are adding is 'Cats/Dogs', I am posting 'Cats[SLASH]Dogs' to the controller, and in the controller changing it back to 'Cats/Dogs'. Obviously this is a horrible hack, so I must be missing something. Any help would be greatly appreciated.

• Using HtmlAnchor for anchor tag that navigates in-page named anchor

  - by Frank Schwieterman

  I am trying to render a simple hyperlink that links to a named anchor within the page, for example: <a href="#namedAnchor"scroll to down</a <a name="namedAnchor"down</a The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Test.ascx.cs" Inherits="TestWebApplication1.controls.Test" % <a href="#namedAnchor" runat="server"HtmlAnchor</a <asp:HyperLink NavigateUrl="#namedAnchor" runat="server"HyperLink</asp:HyperLink The generated source looks like: <a href="controls/#namedAnchor"HtmlAnchor</a <a href="controls/#namedAnchor"HyperLink</a I really just want: <a href="#namedAnchor"HtmlAnchor</a <a href="#namedAnchor"HyperLink</a I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I'm pursuing is not that important and it would be hard to talk the team into abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.

• TFS 2010 - TF14040 The Folder may not be checked out.

  - by Patricker

  I have a .NET 4 website in VS2010 stored in a TFS 2010 team project. I need to add a reference to System.Data.Linq.dll to the website. I am referencing a LINQ DataContext that is defined in another project and I get build errors saying that I need the reference to System.Data.Linq. I go up to the "Add Reference" menu option and add it like I would any normal reference, and it even shows up in the Web.config and in the Properties pages for the website... BUT if I build I still get the same error. So I found a place in my code where I was referencing the LINQ count function and it told me it was invalid because I was missing a reference and it offered to add the reference automatically. I told it to add the reference automatically and it is at this point that I get the error mentioned in the subject: TF14040: The folder $/Folder/Subfolder may not be checked out. No items were checked out I've done some research online but I haven't been able to find much. I saw on a blog that making the folder not readonly fixed the issue for him, but it didn't seem to work for me unless I misunderstood something. I tried loading up the project from source control onto a fresh computer where that project had never been loaded before and I can reproduce the issue the same way. Help would be greatly appreciated.

• How to insert inline content from one FlowDocument into another?

  I'm building an application that needs to allow a user to insert text from one RichTextBox at the current caret position in another one. I spent a lot of time screwing around with the FlowDocument's object model before running across this technique - source and target are both FlowDocuments: using (MemoryStream ms = new MemoryStream()) { TextRange tr = new TextRange(source.ContentStart, source.ContentEnd); tr.Save(ms, DataFormats.Xaml); ms.Seek(0, SeekOrigin.Begin); tr = new TextRange(target.CaretPosition, target.CaretPosition); tr.Load(ms, DataFormats.Xaml); } This works remarkably well. The only problem I'm having with it now is that it always inserts the source as a new paragraph. It breaks the current run (or whatever) at the caret, inserts the source, and ends the paragraph. That's appropriate if the source actually is a paragraph (or more than one paragraph), but not if it's just (say) a line of text. I think it's likely that the answer to this is going to end up being checking the target to see if it consists entirely of a single block, and if it does, setting the TextRange to point at the beginning and end of the block's content before saving it to the stream. The entire world of the FlowDocument is a roiling sea of dark mysteries to me. I can become an expert at it if I have to (per Dostoevsky: "Man is the animal who can get used to anything."), but if someone has already figured this out and can tell me how to do this it would make my life far easier.

• Why can't Perl's DBD::DB2 find dbivport.h during installation?

  - by Liju Mathew

  We are using a Perl utility to dump data from DB2 database. We installed DBI package and it is asking for DBD package also. We dont have root access and when we try to install DBD package we are getting the following error: ERROR BUILDING DB2.pm [lijumathew@intblade03 DBD-DB2-1.78]$ make make[1]: Entering directory '/home/lijumathew/lperl/perlsrc/DBD-DB2-1.78/Constants' gcc -c -I"/db2/db2tf1/sqllib/include" -D_REENTRANT -D_GNU_SOURCE -DDEBUGGING -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O2 -g -pipe -m32 -march=i386 -mtune=pentium4 -DVERSION=\"1.78\" -DXS_VERSION=\"1.78\" -fPIC "-I/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE" Constants.c Running Mkbootstrap for DBD::DB2::Constants () chmod 644 Constants.bs rm -f ../blib/arch/auto/DBD/DB2/Constants/Constants.so gcc -shared -L/usr/local/lib Constants.o -o ../blib/arch/auto/DBD/DB2/Constants/Constants.so chmod 755 ../blib/arch/auto/DBD/DB2/Constants/Constants.so cp Constants.bs ../blib/arch/auto/DBD/DB2/Constants/Constants.bs chmod 644 ../blib/arch/auto/DBD/DB2/Constants/Constants.bs make[1]: Leaving directory `/home/lijumathew/lperl/perlsrc/DBD-DB2-1.78/Constants' gcc -c -I"/db2/db2tf1/sqllib/include" -I"/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBI" -I"/usr/lib/perl5/5.8.5/i386-linux-thread-multi/auto/DBI" -I"/usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi/auto/DBI" -I"/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBI" -D_REENTRANT -D_GNU_SOURCE -DDEBUGGING -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O2 -g -pipe -m32 -march=i386 -mtune=pentium4 -DVERSION=\"1.78\" -DXS_VERSION=\"1.78\" -fPIC "-I/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE" DB2.c In file included from DB2.h:22, from DB2.xs:7: dbdimp.h:10:22: dbivport.h: No such file or directory make: *** [DB2.o] Error 1 How do we fix this?

• Migrating complex SVN branch hierarchy to Mercurial

  - by Christian Hang

  Our team has been using SVN for managing an application of decent size and over time a rather complex hierarchy of branches and tags has built up, which is following the basic standard layout for SVN repositories, but is more nested: |-trunk |-branches | |-releases | | |-releaseA | | `-releaseB | `-features | |-featureX | `-featureY |-tags |-releaseA | |-beta | `-RTP `-releaseB |-beta `-RTP (The feature branches are obviously temporary branches but we have to take them into consideration as it won't be feasible to close all of them at once in the near future) For several reasons but primarily because merges have been becoming an increasing pain, we are considering to switch to Mercurial. The main problem we are currently facing is migrating the existing code base without losing our history. I've tried several migration tools (e.g., yasvn2hg, hg convert and svn2hg) with yasvn2hg being the most promising, but none of them seem to be able to deal with nested hierarchies but they all assume that branches and tags are organized in one flat directory respectively. The choice between named branches or clones as the conversion target of old SVN branches is not a limiting factor in this case, as either solution would be appreciated. We are currently experimenting with both options and how they would fit into our current processes but haven't decided on one yet. I'd obviously be interested in recommendations or experiences with similar setups concerning that issue as well. So, what is the best way to convert a nested SVN branch hierarchy like this to Mercurial? Converting one branch at a time into a separate repository would be quite annoying and I am not sure if that would be the right approach in the first place, depending on how the tools handle historic merges and need to be aware of all other branches?

• Security error accessing Service outside of FlexBuilder

  - by MikeHoss

  I'm very new to Flex and I have what I think it a head-scratcher. I am building a little Flash app that will consume some web services over HTTP. When I am in Flexbuilder and run my app there, it works fine. When I goto to my FlexBuilder project on my OS and double-click on it, it works fine. When I zip up my bin-debug file, I get this error: Security error accessing url faultCode:Channel.Security.Error faultString: 'Security error accessing url' faultDetail:'Destination: DefaultHTTP' So I googled that and got information on about the crossdomain.xml file. Well, I can't put a crossdomain file in the service I am calling, but I can put one somewhere else. So I put the following lines in Flex app: Security.allowDomain("vx1391"); Security.loadPolicyFile("http://vx1391:8080/job/Remote%20FIT%20Runner/ws/trunk/flash-cross-domain.xml"); My cross-domain.xml file is wide-open: &lt;cross-domain-policy&gt; &lt;allow-access-from domain="*"/&gt; </cross-domain-policy> Which I know is bad in a prod enivironment, but right now I just need to get this working locally but outside of FlexBuilder. Anyone want to help out this Flex-noob?

• UIWebView not loading URL when URL is passed from UITableView

  - by Mark Hazlett

  Hey Everyone, So i'm building a webView into my application to show the contents of a URL that I am passing from a selection in a UITableView. I know the UIWebView is loading content properly because if you hard code say http://www.google.ca into the NSURL then it loads fine, however when I'm passing the URL that I parsed from an RSS feed back from the UITableView it won't load the URL properly. I tried the debugger and the URL is coming out as nil right before I try and parse it, however I can use NSLog to print the value of it out to the console. here's the code in my UIViewController that has my UIWebView #import <UIKit/UIKit.h> @interface ReadFeedWebViewController : UIViewController { NSString *urlToGet; IBOutlet UIWebView *webView; } @property(nonatomic, retain) IBOutlet UIWebView *webView; @property(nonatomic, retain) NSString *urlToGet; @end Here's the code for my implementation's viewDidLoad method... // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"Url inside Web View Controller - %@", urlToGet); NSURL *url = [NSURL URLWithString:urlToGet]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:requestObj]; } Once again, I can print the URL to NSLog fine and if I hard code the URL into the NSURL object then it will load fine in the UIWebView. Here is where I'm setting the value in my UITableViewController... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { ReadFeedWebViewController *extendedView = [[ReadFeedWebViewController alloc] init]; int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; extendedView.urlToGet = [[stories objectAtIndex: storyIndex] objectForKey:@"link"]; //NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"summary"]); NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"link"]); [self.navigationController pushViewController:extendedView animated:YES]; [extendedView release]; } However, since I can print the value using NSLog in the extendedView view controller I know it's being passed properly. Cheers

• eclipse tomcat debug mode slow - pegs cpu

  - by andersonbd1

  Running Tomcat through eclipse works fine in non-debug mode, but not in debug mode. When I try to start the Tomcat server in debug mode, the console output looks fine for a while, but then starts slowing down and eventually just stops, pegging the cpu at 100%. I don't think it's relevant, but just in case - here's the console output right about when it starts slowing down and eventually stopping (by stopping I mean no more console output, but still 100% cpu). 2009-09-02 14:35:30,859 INFO NONE org.springframework.context.weaving.DefaultContextLoadTimeWeaver:72 - Found Spring's JVM agent for instrumentation 2009-09-02 14:35:49,562 INFO NONE org.springframework.beans.factory.support.DefaultListableBeanFactory:414 - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@ed889d: defining beans [... 2009-09-02 14:37:31,031 INFO NONE org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:221 - Building JPA container EntityManagerFactory for persistence unit ... I tried everything I could think of to fix it: cleanesd tomcat working directory restarted eclipse restarted Windows refreshed/cleaned all projects I first had this problem last week using eclipse ganymede. I had been running fine in debug-mode for several months prior to this issue. I didn't make any significant changes to our project that would cause this. Eventually, I upgraded to eclipse galileo which solved my problem. Now 2 days later, I'm having the same problem in galileo. Like I said it works fine in non-debug mode. Any help is much appreciated. I should add that other things work in debug mode - for instance junit tests, so it is something specific to tomcat.
