• 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

• How do you parse the XDG/gnome/kde menu/desktop item structure in c++??

  - by Joe Soul-bringer

  I would like to parse the menu structure for Gnome Panels (the standard Gnome Desktop application launcher) and it's KDE equivalent using c/c++ function calls. That is, I'd like a list of what the base menu categories and submenu are installed in a given machine. I would like to do with using fairly simple c/c++ function calls (with NO shelling out please). I understand that these menus are in the standard xdg format. I understand that this menu structure is stored in xml files such as: /home/user/.config/menus/applications.menu I've look here: http://www.freedesktop.org/wiki/Specifications/menu-spec?action=show&redirect=Standards%2Fmenu-spec but all they offer is the standard and some shell files to insert item entries (I don't want shell scripts, I don't want installation, I definitely don't want to create a c-library from the XDG specification. I want to find the existing menu structure). I've looked here: http://library.gnome.org/admin/system-admin-guide/stable/menustructure-13.html.en for more notes on these structures. None of this gives me a good idea of how determine the menu structures using a c/c++ program. The actual gnome menu structures seem to be a horrifically hairy things - they don't seem to show the menu structure but to give an XML-coded description of all the changes that the menus have gone through since installation. I assume gnome panels parses these file so there's a function buried somewhere to do this but I've yet to find where that function is after scanning library.gnome.org for a couple of days. I've scanned the Nautilus source code as well but Panels seem to exist elsewhere or are burried well. Thanks in advance

• Another rsAccessDenied problem with SSRS

  - by Rich.Carpenter

  I've read through a lot of posts regarding the problem, but none of the proposed solutions have worked for me. I continue to get an error stating, "The permissions granted to user '\Rich' are insufficient for performing this operation. (rsAccessDenied)." If I am logged in as the local administrator account, entering the Reporting Services URL in IE doesn't give me that error, but it takes me to a blank page. I haven't been able to get to a SSRS home page at all. Order of operations: I installed and patched Windows 7 Ultimate 64-bit I installed SQL Server Express 2008 with Advanced Services using the MS web installer. I downloaded and installed SP1 for SQL Server Express 2008. I've tried running IE as administrator, adding local machine to trusted sites, and just about every other suggestion I've found. I even ran the entire installation logged in as the local administrator. Nothing seems to work. Could someone please tell me, considering the above installation process, what I should expect to do after to make this work?

• How to speed up an already cached pip install?

  - by Maxime R.

  I frequently have to re-create virtual environments from a requirements.txt and I am already using $PIP_DOWNLOAD_CACHE. It still takes a lot of time and I noticed the following: Pip spends a lot of time between the following two lines: Downloading/unpacking SomePackage==1.4 (from -r requirements.txt (line 2)) Using download cache from $HOME/.pip_download_cache/cached_package.tar.gz Like ~20 seconds on average to decide it's going to use the cached package, then the install is fast. This is a lot of time when you have to install dozens of packages (actually enough to write this question). What is going on in the background? Are they some sort of integrity checks against the online package? Is there a way to speed this up? edit: Looking at: time pip install -v Django==1.4 I get: real 1m16.120s user 0m4.312s sys 0m1.280s The full output is here http://pastebin.com/e4Q2B5BA. Looks like pip is spending his time looking for a valid download link while it already has a valid cache of http://pypi.python.org/packages/source/D/Django/Django-1.4.tar.gz. Is there a way to look for the cache first and stop there if versions match?

• Oracle DBMS_PROFILER only shows Anonymous in the results tables

  - by Greg Reynolds

  I am new to DBMS_PROFILER. All the examples I have seen use a simple top-level procedure to demonstrate the use of the profiler, and from there get all the line numbers etc. I deploy all code in packages, and I am having great difficulty getting my profile session to populate the plsql_profiler_units with useful data. Most of my runs look like this: RUNID RUN_COMMENT UNIT_OWNER UNIT_NAME SECS PERCEN ----- ----------- ----------- -------------- ------- ------ 5 Test <anonymous> <anonymous> .00 2.1 Profiler 5 Test <anonymous> <anonymous> .00 2.1 Profiler 5 Test <anonymous> <anonymous> .00 2.1 Profiler I have just embedded the calls to the dbms_profiler.start_profiler, flush_data and stop_profiler as per all the examples. The main difference is that my code is in a package, and calls in to other package. Do you have to profile every single stored procedure in your call stack? If so that makes this tool a little useless! I have checked http://www.dba-oracle.com/t_plsql_dbms_profiler.htm for hints, among other similar sites.

• Internet zone is opened when broswer is opened from installer created by .Net 3.5sp1

  - by priya

  Hi All, I have project created in VS2005 and .Net 2.0. The installation is a web-based installation. After installing the proe-requisites the installer opens up the browser to continue with web-based install. On this, it opens up in intranet zone and works perfectly. I recently migrated the project to VS2008 Sp1 and .Net 3.5sp1. No change in my code and the test environment. Here the browser gets opened up in the Internet zone which prevents it from moving forward, until unless I open up a new browser manually and copy paste the url. The internet security options on the both the case are - Internet --- High. For the case2, if i have the security internet option to be 'Medium', it works well. I am not sure why this issue comes up when I change the VS and .Net version. More over the browser gets opened with system priveleges rather than administrator privileges. Please let me know any solution on this. Thanks, Priya.R

• SSIS Transaction with Sql Transaction

  - by Mike

  I started with a package to make sure Transactions are working correctly. The package level transaction is set to Required. I have two Execute Sql Task, one deletes rows from a table and one does 1/0, to throw the error. Both task are set to supported transaction level and Serializable IsolationLevel. That works. Now when I replace my two sql task to two separate procedure calls, the first one, ChargeInterest, runs successful but the second one, PaymentProcess, fails always saying. [Execute SQL Task] Error: Executing the query "Exec [proc_xx_NotesReceivable_PaymentProcess] ..." failed with the following error: "Uncommittable transaction is detected at the end of the batch. The transaction is rolled back.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. PaymentProcess being the second stored procedure. Both procedures have there own BEGIN, COMMIT AND ROLLBACKS inside the SP. I believe that the transactions are being successfully handed in the Charge Interest because I can run the following without issues or the dreaded you started with 0 and now have 1 transaction. EXEC [proc_XX_NotesReceivable_ChargeInterest] 'NR', 'M', 186, 300 EXEC [proc_XX_NotesReceivable_PaymentProcess] 'NR', 186, 300 --OR GO BEGIN TRAN EXEC [proc_XX_NotesReceivable_ChargeInterest] 'NR', 'M', 186, 300 EXEC [proc_XX_NotesReceivable_PaymentProcess] 'NR', 186, 300 ROLLBACK TRAN Now I have noticed that DTC does get kicked off in both instances? Why I am not sure because it is using the same connection. In the live example I can see the transaction get started but disappears if I put a breakpoint on the PreExecute event of the second stored procedure. What is the correct way to mingle SP transactions with SSIS transactions?

• What happens to existing workspaces after upgrading to TFS 2010

  - by e-mre

  Hi, I was looking for some insight about what happens to existing workspaces and files that are already checked-out on people, after an upgrade to TFS2010. Surprisingly enough I can not find any satisfactory information on this. (I am talking about upgrading on new hardware by the way. Fresh TFS instance, upgraded databases) I've checked TFS Installation guide, I searched through the web, all I could find is upgrade scenarios for the server side. Nobody even mentions what happens to source control clients. I've created a virtual machine to test the upgrade process, The upgrade was successful and all my files and workspaces exist in the new server too. The problem is: The new TFS installation has a new instanceID. When I redirected on the clients to the new server, the client seemed unable to match files and file states in the workspace with the ones on the new server. This makes me wonder if it will be possible to keep working after the production upgrade. As I mentioned above I can not find anything on this, it would be great if anyone could point me to some paper or blog post about this. Thanks in advance...

• What would be the best way to install (distribute) dynamic libraries in Mac OSX using CMake/Cpack ?

  - by YuppieNetworking

  Hello all, I have a project whose artifacts are two dynamic libraries, let's say libX.dylib and libY.dylib (or .so for linux distributions). There are no executables. Now I would like to distribute these libraries. Since I already use CMake to compile it, I looked at CPack and successfully generated .tgz and .deb packages for Linux. However, for Mac OSX I have no idea and the CPack Wiki about its generators did not help me much. I managed to generate a PackageMaker package, but as clearly stated at this packagemaker howto, there is no uninstall option when using this util. I then read a bit about Bundles, but I feel lost specially since I have no executable. Question: What is the correct way to generate a package for Mac OSX using CPack? My ideal scenario would be either something that installs as easily as a bundle or as a deb file in debian/ubuntu. Thanks for your help Edit One more detail: the code to one of these libraries is not open, so I can't expect the users to do a cmake; make; make install That's why I want a .deb, .tar.gz, bundle or whatsoever.

• comma separated values in oracle function body

  - by dmitry

  I've got following oracle function but it does not work and errors out. I used Ask Tom's way to convert comma separated values to be used in select * from table1 where col1 in <> declared in package header: TYPE myTableType IS table of varchar2 (255); Part of package body: l_string long default iv_value_with_comma_separated|| ','; l_data myTableType := myTableType(); n NUMBER; begin begin LOOP EXIT when l_string is null; n := instr( l_string, ',' ); l_data.extend; l_data(l_data.count) := ltrim( rtrim( substr( l_string, 1, n-1 ) ) ); l_string := substr( l_string, n+1 ); END LOOP; end; OPEN my_cursor FOR select * from table_a where column_a in (select * from table (l_data)); CLOSE my_cursor END; above fails but it works fine when I remove select * from table (l_data) Can someone please tell me what I might be doing wrong here??

• Assign sage variable values into R objects via sagetex and Sweave

  - by sheed03

  I am writing a short Sweave document that outputs into a Beamer presentation, in which I am using the sagetex package to solve an equation for two parameters in the beta binomial distribution, and I need to assign the parameter values into the R session so I can do additional processing on those values. The following code excerpt shows how I am interacting with sage: <<echo=false,results=hide>>= mean.raw <- c(5, 3.5, 2) theta <- 0.5 var.raw <- mean.raw + ((mean.raw^2)/theta) @ \begin{frame}[fragile] \frametitle{Test of Sage 2} \begin{sagesilent} var('a1, b1, a2, b2, a3, b3') eqn1 = [1000*a1/(a1+b1)==\Sexpr{mean.raw[1]}, ((1000*a1*b1)*(1000+a1+b1))/((a1+b1)^2*(a1+b1+1))==\Sexpr{var.raw[1]}] eqn2 = [1000*a2/(a2+b2)==\Sexpr{mean.raw[2]}, ((1000*a2*b2)*(1000+a2+b2))/((a2+b2)^2*(a2+b2+1))==\Sexpr{var.raw[2]}] eqn3 = [1000*a3/(a3+b3)==\Sexpr{mean.raw[3]}, ((1000*a3*b3)*(1000+a3+b3))/((a3+b3)^2*(a3+b3+1))==\Sexpr{var.raw[3]}] s1 = solve(eqn1, a1,b1) s2 = solve(eqn2, a2,b2) s3 = solve(eqn3, a3,b3) \end{sagesilent} Solutions of Beta Binomial Parameters: \begin{itemize} \item $\sage{s1[0]}$ \item $\sage{s2[0]}$ \item $\sage{s3[0]}$ \end{itemize} \end{frame} Everything compiles just fine, and in that slide I am able to see the solutions to the three equations respective parameters in that itemized list (for example the first item in the itemized list from that beamer slide is outputted as [a1=(328/667), b1=(65272/667)] (I am not able to post an image of the beamer slide but I hope you get the idea). I would like to save the parameter values a1,b1,a2,b2,a3,b3 into R objects so that I can use them in simulations. I cannot find any documentation in the sagetex package on how to save output from sage commands into variables for use with other programs (in this case R). Any suggestions on how to get these values into R?

• C headers: compiler specific vs library specific?

  - by leonbloy

  Is there some clear-cut distinction between standard C *.h header files that are provided by the C compiler, as oppossed to those which are provided by a standard C library? Is there some list, or some standard locations? Motivation: int this answer I got a while ago, regarding a missing unistd.h in the latest TinyC compiler, the author argued that unistd.h (contrarily to sys/unistd.h) should not be provided by the compiler but by your C library. I could not make much sense of that response (for one thing shouldn't that also apply to, say, stdio.h?) but I'm still wondering about it. Is that correct? Where is some authoritative reference for this? Looking in other compilers, I see that other "self contained" POSIX C compilers that are hosted in Windows (like the GCC toolchain that comes with MinGW, in several incarnations; or Digital Mars compiler), include all header files. And in a standard Linux distribution (say, Centos 5.10) I see that the gcc package provides a few header files (eg, stdbool.h, syslimits.h) in /usr/lib/gcc/i386-redhat-linux/4.1.1/include/, and the glibc-headers package provides the majority of the headers in /usr/include/ (including stdio.h, /usr/include/unistd.h and /usr/include/sys/unistd.h). So, in neither case I see support for the above claim.

• Cannot install windows service

  - by Matthew Dalton

  I have created a very simple window service using visual studio 2010 and .Net 4.0. This service has no functionality added from the default windows service project, other than an installer has been added. If i run installutil.exe appName.exe on my dev box or other windows 2008 R2 machines in our domain the windows service installs without issue. When i try to do this same thing on our customer site, it fails to install with the following error. Microsoft (R) .NET Framework Installation utility Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved. Exception occurred while initializing the installation: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\TestService\WindowsService1.exe' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515). This solution has only 1 project and no dependencies added. I have tried it on multiple machines in our environment and two in our customers. The machines are all windows 2008 R2, both fresh installs. One machine has just .net 2.0 and .net 4.0. The other .net 2, 3, 3.5 and 4. I am a local admin on each of the machines. I have also tried the 64bit installer but get the following error, so i think the 32 bit one is the one to use. System.BadImageFormatException Any guidance would be appreciated. Thanks.

• rabbitmq-erlang-client, using rebar friendly pkg, works on dev env fails on rebar release

  - by lfurrea

  I am successfully using the rebar-friendly package of rabbitmq-erlang-client for a simple Hello World rebarized and OTP "compliant" app and things work fine on the dev environment. I am able to fire up an erl console and do my application:start(helloworld). and connect to the broker, open up a channel and communicate to queues. However, then I proceed to do rebar generate and it builds up the release just fine, but when I try to fire up from the self contained release package then things suddenly explode. I know rebar releases are known to be an obscure art, but I would like to know what are my options as far as deployment for an app using the rabbitmq-erlang-client.

• Worklight console app, update

  - by jarkko

  We're using Worklight 6.1.0.0 / WebSphere 8.0.0.2 (ND/aix). This seemed pretty close to my question too, but for version 6.0. I've successfully done uninstall/install to our worklight console war package. However, there is some extra work on re-deploying adapters and such. I was looking for a way to just update the console. Among the ant tasks there is a target 'minimal-update', which sounds like what I'm looking for (is it?). However when all other pieces fell into place, I have an error for mapping the datasources: ADMA0007E: A validation error occurred in task Mapping resource references to resources. The Java Naming and Directory Interface (JNDI) name is not specified for resource reference jdbc/WorklightDS in module Worklight with EJB name . Contents of the 'minimal-update' task is pretty much the same as for 'install'. I tried that as update from websphere admin console (but i should use the ant task - right?), that gave me a wizard screen to map jdbc/WorklightDS from package to jdbc/WorklightDS on server. This left me wondering how could I tell this using the ant task.

• Installing Mercurial on Windows Apache XAMPP Tutorial

  - by Tim Dellas

  After asking this question (http://stackoverflow.com/questions/2675764/xampp-mercurial-installation-on-windows-apache-hgwebdir-cgi-script-error) and reading though the whole internet including this question (http://stackoverflow.com/questions/644322/how-do-i-get-mercurials-hgwebdir-working-on-windows) and all its links for about 10 hours, I seem to not be able to find a solution. I begun with this tutorial http://mercurial.selenic.com/wiki/HgWebDirStepByStep ... and I really don't want to install ancient versions of Mercurial. I got my windows-apache to run Python scripts, CGI-Scripts, publish them in the wild, but hgwebdir just won't work. Question 1: Can someone please enrich his personal blog with a tutorial on how to install MERCURIAL on a WINDOWS XAMPP installation and make it visible to the world? I guarantee a lot of pageviews, as this is not a trivial problem. And this would sincerely help a lot of other people I guess. Question 2: For example, even after browsing half a day through everywhere, I just cannot find out, which version of python I need to pair with the freshest version of mercurial, and I get the "magic number is wrong"-error. This would be my question, if noone has time to make up a nice blogpost. Sorry for being a bit frustrated.

• How do I use an index in an array reference as a method reference in Perl?

  - by Robert P

  Similar to this question about iterating over subroutine references, and as a result of answering this question about a OO dispatch table, I was wondering how to call a method reference inside a reference, without removing it first, or if it was even possible. For example: package Class::Foo; use 5.012; #Yay autostrict! use warnings; # a basic constructor for illustration purposes.... sub new { my $class = shift; return bless {}, $class; } # some subroutines for flavor... sub sub1 { say 'in sub 1' } sub sub2 { say 'in sub 2' } sub sub3 { say 'in sub 3' } # and a way to dynamically load the tests we're running... sub sublist { my $self = shift; return [ $self->can('sub1'); $self->can('sub3'}; $self->can('sub2'); ]; } package main; my $instance = Class::Foo->new(a => 1, b => 2, c => 3); my $tests = $instance->sublist(); my $index = int(rand($#{$tests})); # <-- HERE So, at HERE, we could do: my $ref = $tests->{$index}; $instance->$ref(); but how would we do this, without removing the reference first?

• How to parse time stamps with Unicode characters in Java or Perl?

  - by ram

  I'm trying to make my code as generic as possible. I'm trying to parse install time of a product installation. I will have two files in the product, one that has time stamp I need to parse and other file tells the language of the installation. This is how I'm parsing the timestamp public class ts { public static void main (String[] args){ String installTime = "2009/11/26 \u4e0b\u5348 04:40:54"; //This timestamp I got from the first file. Those unicode charecters are some Chinese charecters...AM/PM I guess //Locale = new Locale();//don't set the language yet SimpleDateFormat df = (SimpleDateFormat)DateFormat.getDateTimeInstance(DateFormat.DEFAULT,DateFormat.DEFAULT); Date instTime = null; try { instTime = df.parse(installTime); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(instTime.toString()); } } The output I get is Parsing Failed java.text.ParseException: Unparseable date: "2009/11/26 \u4e0b\u5348 04:40:54" at java.text.DateFormat.parse(Unknown Source) at ts.main(ts.java:39) Exception in thread "main" java.lang.NullPointerException at ts.main(ts.java:45) It throws exception and at the end when I print it, it shows some proper date... wrong though. I would really appreciate if you could clarify me on these doubts How to parse timestamps that have unicode characters if this is not the proper way? If parsing is failed, how could instTime able to hold some date, wrong though? I know its some chinese,Korean time stamps so I set the locale to zh and ko as follows.. even then same error comes again Locale = new Locale("ko"); Locale = new Locale("ja"); Locale = new Locale("zh"); How can I do the same thing in Perl? I can't use Date::Manip package; Is there any other way?

• Should we retire the term "Context"?

  - by MrGumbe

  I'm not sure if there is a more abused term in the world of programming than "Context." A word that has a very clear meaning in the English language has somehow morphed into a hot mess in software development, where the definition where the connotation can be completely different based on what library you happen to be developing in. Tomcat uses the word context to mean the configuration of a web application. Java applets, on the other hand, use an AppletContext to define attributes of the browser and HTML tag that launched it, but the BeanContext is defined as a container. ASP.NET uses the HttpContext object as a grab bag of state - containing information about the current request / response, session, user, server, and application objects. Context Oriented Programming defines the term as "Any information which is computationally accessible may form part of the context upon which behavioral variations depend," which I translate as "anything in the world." The innards of the Windows OS uses the CONTEXT structure to define properties about the hardware environment. The .NET installation classes, however, use the InstallContext property to represent the command line arguments entered to the installation class. The above doesn't even touch how all of us non-framework developers have used the term. I've seen plenty of developers fall into the subconscious trap of "I can't think of anything else to call this class, so I'll name it 'WidgetContext.'" Do you all agree that before naming our class a "Context," we may want to first consider some more descriptive terms? "Environment", "Configuraton", and "ExecutionState" come readily to mind.
