• I got MVVM 3-Level-Master-Detail Switchting working but with CRUD operations now everything seems st

  - by msfanboy

  Hello, I have 1 UserControl (SchoolclassAdministration.xaml) that is datatemplated with 1 ViewModel (SchoolclassAdministrationViewModel) I have 3 Models and 3 ViewModels in that scenario. Those 3 ViewModels must reflect the requirements of the View. The requirements are 3 "Areas" on the left side and 2 "Areas" on the right side. 3: SchoolclassFormular PupilFormular SubjectFormular Those have all Buttons for Add/Delete 2: PupilsDataGrid SubjectsDataGrid The Master-Detail scenario is between the: SchoolclassFormular = PupilsDataGrid = SubjectsDataGrid The switching of the ViewModelCollections work! My Problem scenario is this: The DataContext is on the SchoolclassAdministrationViewModel what is the ViewModel containing the AllSchoolclassesViewModel ObservableCollection bound to the SchoolclassAdministration.xaml UserControl. My SchoolclassViewModel,PupilViewModel and SubjectViewModel has all Properties, Commands(Add/Delete). My Question: How can I set these 3 ViewModels as DataContext to my ONE SchoolclassAdministration.xaml UserControl I have? Before you answer... putting every ViewModel(schoolclass,pupil,subject) in its own UserControl will not help me because then the Master-Detail switching can NOT work anymore. Every related ViewModels need to be put in a related/ONE UserControl. OK now I can`t wait for an answer because that scenario is driving me nuts for weeks.

• Visual Studio 2008 Web Project error: Unable to start program http://localhost:port

  - by JookyDFW

  I am re-hashing this question because I have looked at over 50 threads in different forums and have not been able to get a resolution to my problem. Here are the specs: Windows XP SP3, Visual Studio 2008 SP1, .NET 3.5, ASP. NET MVC 2 project, IE 7 (was IE 8) Up until a few days ago I was not having any issues. It is now happening on any solution that I try to debug. I start a debug session (F5), the solution rebuilds, a VS development web server starts and then I get this error: Unable to start program http://localhost:2012/ If I open a web browser and enter the URL the application loads up. I had upgraded to IE 8 a few weeks ago and read there may be some issues so it has been uninstalled and I am currently on IE 7. Also, while IE 8 was installed I had switched my default browser to Firefox but my current default broweser is now IE7. I have reveiewed the threads on this site and others and have not been able to fix the issue. Any help would be appreciated.

• Why do I get an error 'Cannot resolve symbol <symbolname>' in ReSharper?

  - by drachenstern

  Using VS2008 and R# 5 I'm running into an odd situation, where on an aspx page I keep getting Cannot resolve symbol 'symbolname' But the code compiles and runs fine. While having a fix for this would be great, I'm just trying to figure out if I'm losing my mind. The CodeFile directive and Inherits directives are fine. If I compile the app or just let devenv sit for a bit it'll go away, but as soon as I save the aspx [via ctrl+s] R# suddenly has trouble with the Inherits attribute and flips out on every method in the page (OnClick etc). // Anonymized of course but otherwise intact <%@ Page AutoEventWireup="true" CodeFile="TestPage.aspx.cs" Inherits="TestPage" Language="C#" MasterPageFile="~/MasterPage.master" Title="Test Page Title" %> This is mostly just a grievance, because since the code compiles it doesn't stop me from doing what I need. I would post a bug report to the JetBrains site but first I would like to know I'm not alone. It could be my machine. Maybe when I roll to VS2010 in a couple weeks this will go away?

• Rails test db doesn't persist record changes

  - by nathan.f77

  I've been trying to solve a problem for a few weeks now. I am running rspec tests for my Rails app, and they are working fine except for one error that I can't seem get my head around. I am using MySQL with the InnoDB engine. I have set config.use_transactional_fixtures = true in spec_helper.rb I load my test fixtures manually with the command rake spec:db:fixtures:load. The rspec test is being written for a BackgrounDRb worker, and it is testing that a record can have its state updated (through the state_machine gem). Here is my problem: I have a model called Listings. The rspec test calls the update_sold_items method within a file called listing_worker.rb. This method calls listing.sell for a particular record, which sets the listing record's 'state' column to 'sold'. So far, this is all working fine, but when the update_sold_items method finishes, my rspec test fails here: listing = Listing.find_by_listing_id(listing_id) listing.state.should == "sold" expected: "sold", got: "current" (using ==) I've been trying to track down why the state change is not persisting, but am pretty much lost. Here is the result of some debugging code that I placed in the update_sold_items method during the test: pp listing.state # => "current" listing.sell! listing.save! pp listing.state # => "sold" listing.reload pp listing.state # => "current" I cannot understand why it saves perfectly fine, but then reverts back to the original record whenever I call reload, or Listing.find etc. Thanks for reading this, and please ask any questions if I haven't given enough information. Thanks for your help, Nathan B P.S. I don't have a problem creating new records for other classes, and testing those records. It only seems to be a problem when I am updating records that already exist in the database.

• Pseudocode: a clear definition?

  - by Cian E

  The following code is an example of what I think would qualify as pseudocode, since it does not execute in any language but the logic is correct. string checkRubric(gpa, major) bool brake = false num lastRange num rangeCounter string assignment = "unassigned" array bus['business']= array('person a'=>array(0, 2.9), 'person b'=>array(3, 4)) array cis['computer science']= array('person c'=>array(0, 2.9), 'person d'=>array(3, 4)) array lib['english']= array('person e'=>array(0, 4)) array rubric = array(bus, cis, lib) foreach (rubric as fieldAr) foreach (fieldAr as field => advisorAr) if (major == field) foreach (advisorAr as advisor => gpaRangeAr) rangeCounter = 0 foreach (gpaRangeAr as gpaValue) if (rangeCounter < 1) lastRange = gpaValue else if (gpa >= lastRange && gpa <= gpaValue) assignment = advisor brake = true break endif rangeCounter++ endforeach if (brake == true) break endif endforeach if (brake == true) break endif endif endforeach if (brake == true) break endif endforeach return assignment For the past couple of weeks I've been trying to create a clear definition of what pseudocode actually is. Is it relative to the programmer or is there an actual clearcut syntax? I say pseudocode is any code that does not execute, how about you? Thanks (links to this subject welcome)

• Cannot add SourceSafe Database as Visual Studio 2010 source control.

  - by CletusLoomis

  My issue is that I cannot add SourceSafe Database for source control within Visual Studio 2010. Our team was initially using VSS for source control in Visual Studio 2010. During an evaluation of TFS, I switched my source control to TFS. It will be a few weeks before a decision is made on TFS, so I needed to switch my source control back to VSS. However I'm now unable to add a SourceSafe Database in Visual Studio. Steps to Reproduce in Visual Studio 2010: 1) Access the 'Open SourceSafe Database' form via Tools-Options-Source Control-Plug-in Settings--Advanced or via File-Source Control 2) The list of available database is blank so I choose 'Browse'. 3) I browse to the srcsafe.ini file for my VSS database and select it. 4) I'm promted to confirm the Database Name - Click OK. 5) The database does not appear in the 'Open SourceSafe' Database form. The list of available databases is still blank. Note that I can add the database fine outside of Visual Studio using VSS directly. However the databases I add via VSS do not appear in the Visual Studio forms. I'm suspicious that this is related to "down-grading" from TFS to VSS which may not have been heavily tested at MS. Any assistance is appreciated.

• Regex query: how can I search PDFs for a phrase where words in that phrase appear on more than one l

  - by Alison

  I am trying to set up an index page for the weekly magazine I work on. It is to show readers the names of companies mentioned in that weeks' issue, plus the page numbers they are appear on. I want to search all the PDF files for the week, where one PDF = one magazine page (originally made in Adobe InDesign CS3 and Adobe InCopy CS3). I have set up a list of companies I want to search for and, using PowerGREP and using delimited regular expressions, I am able to find most page numbers where a company is mentioned. However, where a company name contains two or more words, the search I am running will not pick up instances where the name appears over more than one line. For example, when looking for "CB Richard Ellis" and "Cushman & Wakefield", I got no result when the text appeared like this: DTZ beat BNP PRE, CB [line break here] Richard Ellis and Cushman & [line break here] Wakefield to secure the contract. [line end here] Could someone advise me on how to write a regular expression that will ignore white space between words and ignore line endings OR one that will look for the words including all types of white space (ie uneven spaces between words; spaces at the end of lines or line endings; and tabs (I am guessing that this info is imbedded somehow in PDF files). Here is a sample of the set of terms I have asked PowerGREP to search for: \bCB Richard Ellis\b \bCB Richard Ellis Hotels\b \bCentaur Services\b \bChapman Herbert\b \bCharities Property Fund\b \bChetwoods Architects\b \bChurch Commissioners\b \bClive Emson\b \bClothworkers’ Company\b \bColliers CRE\b \bCombined English Stores Group\b \bCommercial Estates Group\b \bConnells\b \bCooke & Powell\b \bCordea Savills\b \bCrown Estate\b \bCushman & Wakefield\b \bCWM Retail Property Advisors\b [Note that there is a delimited hard return between each \b at the end of each phrase and beginnong of the next phrase.] By the way, I am a production journalist and not usually involved in finding IT-type solutions and am finding it difficult to get to grips with the technical language on the PowerGREP site. Thanks for assistance Alison

• What do you do when your team leader doesn't know something simple?

  - by leppie

  What do you do when your team leader does not know why the following is wrong: a.SomeProp = a.SomeProp; // no funny side-effects, plain old property He claims 15 years of programming experience, and 7 years of C#/.NET. To me, someone of 3-6 months experience should know this. What I have done: Tried to make him understand why it is wrong. He told me not to criticize him. Told him it's not about criticism, but project risk. He got upset with me. I have addressed the risk of this person with our manager (few weeks back). I have addressed my concerns with this person with our manager several times, since 1 month after I started there (7 months now). Currently, I just feel like just not going back to work... I hardly have any nails left, and this is really just the tip of the iceberg. As nothing has changed after I have spoken to the manager for the last 6 months, I feel like I need to make some sort of ultimatum. Do you have any suggestions? PS: Please do not make this subjective. I have no need for arguing. The level of incompetence is pretty clear. I just need some advice before going insane. Update: Thanks for all the answers (trying to update before close, buggers). I think I will forward this thread to our manager :) Update 2: I sent my manager another mail with my concerns, and a link to this question. Awaiting response.

• Regression Testing and Deployment Strategy

  - by user279516

  I'd like some advice on a deployment strategy. If a development team creates an extensive framework, and many (20-30) applications consume it, and the business would like application updates at least every 30 days, what is the best deployment strategy? The reason I ask is that there seems to be a lot of waste (and risk) in using an agile approach of deploying changes monthly, if 90% of the applications don't change. What I mean by this is that the framework can change during the month, and so can a few applications. Because the framework changed, all applications should be regression-tested. If, say, 10 of the applications don't change at all during the year, then those 10 applications are regression-tested EVERY MONTH, when they didn't have any feature changes or hot fixes. They had to be tested simply because the business is rolling updates every month. And the risk that is involved... if a mission-critical application is deployed, that takes a few weeks, and multiple departments, to test, is it realistic to expect to have to constantly regression-test this application? One option is to make any framework updates backward-compatible. While this would mean that applications don't need to change their code, they would still need to be tested because the underlying framework changed. And the risk involved is great; a constantly changing framework (and deploying this framework) means the mission-critical app can never just enjoy the same code base for a long time. These applications share the same database, hence the need for the constant testing. I'm aware of TDD and automated tests, but that doesn't exist at the moment. Any advice?

• Limit the number of rows returned on the server side (forced limit)

  - by evolve

  So we have a piece of software which has a poorly written SQL statement which is causing every row from a table to be returned. There are several million rows in the table so this is causing serious memory issues and crashes on our clients machine. The vendor is in the process of creating a patch for the issue, however it is still a few weeks out. In the mean time we were attempting to figure out a method of limiting the number of results returned on the server side just as a temporary fix. I have no real hope of there being a solution, I've looked around and don't really see any ways of doing this, however I'm hoping someone might have an idea. Thank you in advance. EDIT I forgot an important piece of information, we have no access to the source code so we can not change this on the client side where the SQL statement is formed. There is no real server side component, the client just accesses the database directly. Any solution would basically require a procedure, trigger, or some sort of SQL-Server 2008 setting/command.

• ntpd on Fedora Core 6 with high negative time rest values

  - by Mark White

  The basic problem is we have a FC6 server instance running on a virtual machine, and the system time seems to have been slowly varying until it is now causing a problem. The server runs 24/7 and has been up for 155 days. It has been changed to show GMT, and reports the time as (example) 00:15:15 GMT whereas the actual time is 00:00:00 GMT. This is an offset of 915 seconds. selinux has been changed to 'setenforce 0' for testing and I am running as root. I stop the ntpd service and change the time in System|Administration|Date & Time. The time still shows the same with 'date' in bash. There are no error logs. I change the date with 'date --set' in bash. The response confirms the changed date. I run 'date' and the incorrect date is shown. There are no error logs. I start the ntpd service and /var/log/messages shows success with 'time reset -915.720139s'. The date remains unchanged. ntpq -p shows three three time servers all have offsets of around -915 seconds. I stop ntpd service and try 'ntpd -gqx' and get the same result as above - success, but a large negative time reset. I've tried varying combinations of the above, and a few more settings in System|Administration|Date & Time - no change. I just need to reset the system time to GMT. No offset. But I can't wait for ntpd to slew the time over the next few weeks. Any advice is welcome, cheers! Sure this shouldn't be this difficult... Mark...

• Method for finding memory leak in large Java heap dumps

  - by Rickard von Essen

  I have to find a memory leak in a Java application. I have some experience with this but would like advice on a methodology/strategy for this. Any reference and advice is welcome. About our situation: Heap dumps are larger than 1 GB We have heap dumps from 5 occasions. We don't have any test case to provoke this. It only happens in the (massive) system test environment after at least a weeks usage. The system is built on a internally developed legacy framework with so many design flaws that they are impossible to count them all. Nobody understands the framework in depth. It has been transfered to one guy in India who barely keeps up with answering e-mails. We have done snapshot heap dumps over time and concluded that there is not a single component increasing over time. It is everything that grows slowly. The above points us in the direction that it is the frameworks homegrown ORM system that increases its usage without limits. (This system maps objects to files?! So not really a ORM) Question: What is the methodology that helped you succeed with hunting down leaks in a enterprise scale application?

• Does anyone else get worn out using Scrum, finishing sprint after sprint?

  - by Simucal

  I'm with a pretty small startup and we started using a form of a Scrum/Agile development cycle. In many ways I enjoy Scrum. We have relatively short sprints (2 weeks) and I like the Burndown Chart to track the teams progress. I also like the Feature Board so I always know what I should be doing next. It feels good taking down a feature's card from the board, completing it and then putting it in the burn down pile. However, we are now entering in our 18th Sprint release cycle and I'm starting to feel a little burnt out. It isn't that I don't like job or my co-workers, it is just that these sprints are... well, sprints. From start to finish I literally feel like I'm racing against the clock to maintain our development velocity. When we are done with the sprint we spend one day planning the next sprints feature set and estimates and then off we go again. For people who work in a mature Agile/Scrum development process, is this normal? Or are we missing something? Is there normally time in a Scrum enviornment that is unassigned/untracked to get done some minor things and to clear your head?

• adding stock data to amibroker using c#

  - by femi

  hello, I have had a hard time getting and answer to this and i would really , really appreciate some help on this. i have been on this for over 2 weeks without headway. i want to use c# to add a line of stock data to amibroker but i just cant find a CLEAR response on how to instantiate it in C#. In VB , I would do it something like; Dim AmiBroker = CreateObject("Broker.Application") sSymbol = ArrayRow(0).ToUpper Stock = AmiBroker.Stocks.Add(sSymbol) iDate = ArrayRow(1).ToLower quote = Stock.Quotations.Add(iDate) quote.Open = CSng(ArrayRow(2)) quote.High = CSng(ArrayRow(3)) quote.Low = CSng(ArrayRow(4)) quote.Close = CSng(ArrayRow(5)) quote.Volume = CLng(ArrayRow(6)) The problem is that CreateObject will not work in C# in this instance. I found the code below somewhere online but i cant seem to understand how to achieve the above. Type objClassType; objClassType = Type.GetTypeFromProgID("Broker.Application"); // Instantiate AmiBroker objApp = Activator.CreateInstance(objClassType); objStocks = objApp.GetType().InvokeMember("Stocks", BindingFlags.GetProperty,null, objApp, null); Can anyone help me here?

• SimpleDOM sortedXPath date sorting works on localhost but not on remote server.

  - by Imminent

  Here's what i'm trying to do: 1) Take a basic XML page (data.xml) 2) Load it with simpleDOM 3) Use simpleDOM sortedXPath to sort all XML items by their pubDate 4) Display sorted output Here is the code I currently have. My code below outputs exactly what I need when run it on my localhost (XAMPP w/PHP 5.3) but on my remote server (which has at least PHP 5.0+) all is lost and a completely blank page is output. It will output the $xml array with print_r though. Here is my code: <?php include('SimpleDOM.php'); $xml = simpledom_load_file('data.xml'); $dateformat = "D j M, g:ia"; /* print_r($xml); <-array will output on remote server if put here, but alas nothing else beyond this point */ /*Output First 5 items sorted by pubDate*/ foreach($xml->channel->sortedXPath('item','pubDate', SORT_DESC) as $i => $item){ if ($i > 4){ break; } print "<p>This Weeks Deal:<strong> ".$item->title."</strong></p>"; print $item->description; print "<p>Date Posted:<strong> ".date($dateformat, strtotime($item->pubDate))."</strong></p>"; } ?> Like I said, this code seems to work great on my localhost... but not being able to run it on my remote server is making me crazy. Any ideas ?? Any help will be far beyond appreciated.

• Generating the SQL query plan takes 5 minutes, the query itself runs in milliseconds. What's up?

  - by TheImirOfGroofunkistan

  I have a fairly complex (or ugly depending on how you look at it) stored procedure running on SQL Server 2008. It bases a lot of the logic on a view that has a pk table and a fk table. The fk table is left joined to the pk table slightly more than 30 times (the fk table has a poor design - it uses name value pairs that I need to flatten out. Unfortunately, it's 3rd party and I cannot change it). Anyway, it had been running fine for weeks until I periodically noticed a run that would take 3-5 minutes. It turns out that this is the time it takes to generate the query plan. Once the query plan exists and is cached, the stored procedure itself runs very efficiently. Things run smoothly until there is a reason to regenerate and cache the query plan again. Has anyone seen this? Why does it take so long to generate the plan? Are there ways to make it come up with a plan faster?

• I do I iterate the records in a database using LINQ when I have already built the LINQ DB code?

  - by Seth Spearman

  I asked on SO a few days ago what was the simplest quickest way to build a wrapper around a recently completed database. I took the advice and used sqlmetal to build linq classes around my database design. Now I am having two problems. One, I don't know LINQ. And, two, I have been shocked to realize how hard it is to learn. I have a book on LINQ (Linq In Action by Manning) and it has helped some but at the end of the day it is going to take me a couple of weeks to get traction and I need to make some progress on my project today. So, I am looking for some help getting started. Click HERE To see my simple database schema. Click HERE to see the vb class that was generated for the schema. My needs are simple. I have a console app. The main table is the SupplyModel table. Most of the other tables are child tables of the SupplyModel table. I want to iterate through each of Supply Model records. I want to grab the data for a supply model and then DoStuff with the data. And I also need to iterate through the child records, for each supply model, for example the NumberedInventories and DoStuff with that as well. I want to only iterate the SupplyModels that are have IDs that are in an array of strings containing the IDs. I need help doing this in VB rather than C# if possible. Thanks for your help. Seth

• Windows update breaks dlls?

  - by shoosh

  I'm compiling a project which uses multiple DLL and compiles with VS2008. After a recent windows update DLLs compiled on my computer stopped working on other computers. After some investigation it turned out that it updated the CRT redistributable library which I'm compiling with from version "9.0.21022.8" to version "9.0.30729.4148" This is evident from the Manifest file of the EXE i'm compiling. it contains the following: <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.CRT" version="9.0.21022.8" processorArchitecture="amd64" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.CRT" version="9.0.30729.4148" processorArchitecture="amd64" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> Meaning it wants to use two different versions of the CRT at the same time. the second version is needed by the code which I'm compiling right now and the first version is needed by older dlls which were compiled a few weeks ago. In the computers where the application is deployed this becomes a problem since they get their CRT dll from a local folder called Microsoft.VC90.CRT and not from WinSXS. This folder can't contain two different versions of the dll. Is there a known solution to this issue or do I need to start compiling all of the other DLLs with the new CRT?

• How to organize the work when project needs to be re-implemented due to poor code quality?

  - by Dmitriy Nagirnyak

  Hi, I have joined a very small where one main developer has been buiding the web app (.NET 4.0) during ~6 months. The project should be delivered within next 2 months. After first look at the code I can say that I would never allow it to go to production (things like catch { }, not tests at all with WebForms etc). So the code quality is incredibly low. My task is to improve that and still deliver the solution. So I plan to start with unit testing and MVC2 reimplementing most of the functionality (though using some of the existing code). I estimate that I will need about 6 weeks to catch up with the current progress and be on te same functionality level as the application will be in 6 months. The problem is that the main developer who has been working on the project does not seem to be very 'professional' and skillful (he seems to be really starting in IT and many basic things are unknown to him). It will take significant amount of time and effort to educate him how to do the proper testing, development and apply some patterns. I am ready to take responsibility for the reimplemnting the application but at the same time I don't want the main developer to be on idle but as he won't be able to significantly contribute to the better-world project at this stage I am not sure what would the best way to keep productivity high for both of us. Currently I think following solution is good enough: He proceeds doing what he does until I will catch up with him and then start working on a new project together. The problem is that of course this approach is not very productive as one developer will do better-world project while the other will proceed with what he did, effectively doing similar tasks. Can you suggest how we could better organise the work together in order to be most efficient for the overall project? Thanks, Dmitriy.

• MS-Excel Negative times

  - by oxinabox.ucc.asn.au

  I'm writing a spreadsheet for a shop manager. What it does is keep track of the number of hours a worker has worked. So you enter times for Monday-Sunday, and then an adjustment - e.g. if they work 40/40/40/32 hours for the month, then you would have an adjustment of -2/-2/-2/+6 to bring the worker to the 38 hour week that he's being paid for. Some (most) weeks may be adjusted for overtime. The spreadsheet then totals the hours. This spreadsheet is supposed to just be a self-calculating version of a paper form. It needs to match the paper form as it has to be substituted for the old form which is given to some other member of the company (pay clerk, I don't know; I'm not rebuilding their whole system, just replacing a form) I'm having trouble entering a negative time in the adj field - the field has a [h]:mm formatting. and when i enter a negative time (e.g. -2:00) it displays an error, saying "incorrectly formatted equation", with the suggestion that if I was entering a string then I should prefix with a apostrophe. How do I overcome this?

• Choosing an installer product that is free and will download/install the .NET Framework

  - by Coder7862396

  I'm currently using the Visual Studio Installer (Setup Project) in Visual Studio 2010 as the installer for MyProgram. It has some quirky bugs and is not very customizable so I would like to switch to another installer product. Here are my requirements: Must be free (and licensed for commercial use) Must install the Windows Installer 3.1 and .NET Framework 4.0 if the client doesn't have them The installer will download them if they are not available The code for detecting the .NET Framework and downloading it must be written by Microsoft (I do not want to have to update hard-coded URLs and registry keys in the future). I know that the Windows SDK includes a setup bootstrap that does this (C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper) In the future, when .NET Framework 5 is released and MyProgram uses it, no installer code will need to be changed, the updated installer product should see that MyProgram now uses the .NET Framework version 5 and will install that Here are my current choices: Visual Studio Installer: Automatically detects/downloads/installs Windows Installer and .NET Framework using a bootstrapper Setup.exe (Good!) Limited/buggy functionality (Uninstall shortcuts in the Start Menu cause empty folders to be left behind during uninstall, asking the user if they want a desktop shortcut requires a lot of work, etc.) NSIS: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLS, etc. Inno Setup: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLs, etc. WiX: Steep learning curve... not sure if I want to spend weeks learning it only to find out that it has the same uninstall problem as the Visual Studio Installer (because they both use MSI files) InstallShield LE 2010: Downloading it requires me to setup a fake email account to register just to download it. Then once it is installed it has to contact the company's servers and transmit some private information to them before I'm even allowed to try the free version. This is the most insidious form of DRM that there is and I will not accept it.

• Full text index requires dropping and recreating - why?

  - by Amjid Qureshi

  Hi all, So I've got a web app running on .net 3.5 connected to a SQL 2005 box. We do scheduled releases every 2 weeks. About 14 tables out of 250 are full text indexed. After not every release, but a few too many, the indexes crap out. They seem to have data in there, but when we try to search them from the front end or SQL enterprise we get timeouts/hangs. We have a script that disables the indexes, drops them, deletes the catalog and then re creates the indexes. This fixes the problem 99 times out of 100. and the one other time, we run the script again and it all works We have tried just rebuilding the fulltext index but that doesn't fix the issue. My question is why do we have to do this ? what can we do to sort the index out? Here is a bit of the script, IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[Address]')) ALTER FULLTEXT INDEX ON [dbo].[Address] DISABLE GO IF EXISTS (SELECT * FROM sys.fulltext_indexes fti WHERE fti.object_id = OBJECT_ID(N'[dbo].[Address]')) DROP FULLTEXT INDEX ON [dbo].[Address] GO IF EXISTS (SELECT * FROM sysfulltextcatalogs ftc WHERE ftc.name = N'DbName.FullTextCatalog') DROP FULLTEXT CATALOG [DbName.FullTextCatalog] GO -- may need this line if we get an error BACKUP LOG SMS2 WITH TRUNCATE_ONLY CREATE FULLTEXT CATALOG [DbName.FullTextCatalog] ON FILEGROUP [FullTextCatalogs] IN PATH N'F:\Data' AS DEFAULT AUTHORIZATION [dbo] CREATE FULLTEXT INDEX ON [Address](CommonPlace LANGUAGE 'ENGLISH') KEY INDEX PK_Address ON [DbName.FullTextCatalog] WITH CHANGE_TRACKING AUTO go

• IntelliJ IDEA plugin development: Get classes VirtualFile (or paths) for a specific source VirtualFi

  - by Ran Biron

  Hi all. This is a cross-post from http://www.jetbrains.net/devnet/message/5264436#5264436 - I failed to get any answer on that forum for two weeks now, so I'm re-asking it here (please don't flame). This question refers to plugin development for the IntelliJ IDEA IDE, specifically targeting java development: Is there any API to get the list of .class files for given source file? I'm trying to write a plugin that creates a binary patch jar based on a changelist. I've managed to get the changelist and, from it, a list of source files (VirtualFile). Now I'm trying to get the compiled class files for these source files (I don't mind preforming a "make" or relying on the previous compile output). I've played a bit with ProjectFileIndex but could only find the classes root. I'd hate to do a "dumb" path-based search because inner classes (and inner anonymous classes) would make it difficult to get correctly. Is there such an API? Or am I doomed to parse the paths? Thanks, Ran.

• What's it like being a financial programmer?

  - by Mike

  As a student who's done an internship at a Silicon Valley company(non-financial), I'm curious to know what it's like working for a financial company doing software development. I'd expect the hours to be longer, and the pay to be higher. Specifically, I have the following questions: What's the work/life balance really like? Are you expected to work 80 hours a week most weeks? For those who have worked in non-financial software engineering jobs, how does being a financial software engineer compare in terms of work/life balance? How much does it pay? I'm curious as to starting(i.e. just got a BS) pay, as well as "top out" pay. (I'd prefer concrete numbers - ballpark is fine). Also, bonuses would be useful information. What jobs do financial programmers typically have? Are most just general software engineers, or do people typically have very specialized(i.e. AI or systems) backgrounds? Also, do most programmers have PhDs? Are programmers typically required to be at work, or are financial companies generally flexible about letting programmers work from home? When at work, do programmers have to dress formally? What are the technology environments like? Are finance companies using state-of-the-art hardware and software, or are they generally more conservative in upgrading their equipment? What programming languages are typically used? If VBA(shudder) is used, is it a large part of a finance company's workflow? If you could turn back the clock, would you still be a financial programmer? I'm going to keep this post open a little bit longer to get some more responses.
