• Problem Rendering SIFR with revision 436 on IE6 and IE7

  - by Mark

  Hi, I seem to have a problem with SIFR3. I'm using version 436 and from all my testing it appears to be a problem associated with IE6 and IE7 as I cannot replicate the issue in Firefox, Chrome, Safari for Windows, or even IE8. The problem is occurring on my company's website and can be seen here: http://www.wyldeia.co.uk/blog.php When you first go to the page in IE6 or IE7 it appears to render fine. However if you click away onto another page and then click the back button in the browser, all of the text is replaced by an error saying "Rendered with sIFR3 revision 436". If you refresh the page, then the problem goes away, that is until you browse away and come back again. I've tried this on two separate machines both running IE7.0.6000.16809, and a further separate machine running IE6 which I then upgraded to IE8. I thought initially it might be Flash player related but on upgrading from version 9 to 10 of the flash player the problem remains. Further digging around indicated that the error can be caused by having a corrupted flash font file, or having one present that was generated with a previous revision of SIFR3. However I have exported the flash font file using the supplied fla with revision 436 but the problem remains. Usually I like to track the answer down myself but as it is I'm at a bit of a loss on this one so if anyone has any ideas what might be happening here then I would be very grateful! Regards, Mark

• Personal projects competing with employers projects?

  - by jamesorwood123

  Recently at my place of employment it was discovered that I was developing an outside personal project (personal project being a project I have been working on, in my spare time, for my own purposes, using my personal equipment). My employer has an idea which is very similar to my outside project but has not been started, created, put out to market yet. When I originally started working for the company I signed a non-compete contract. My employer is now saying that because my outside/personal project is similar to theirs that I am now a competitor and breaching my original non-compete agreement. What I would like to know is where do I stand in this situation? Also my personal project has not been fully developed, nor is available to anyone other than myself. So if we both don’t have full/released products (full meaning put out to the public) are we actually competitors? There is going to be a meeting in the coming weeks to discuss this issue and would like to have a proper argument in place. I know some of this conversation is best held with a lawyer but I don’t have the money to do that yet. I’m not looking for full legal advice just anyone who has maybe experienced this or can give any advice. Thanks in advance!

• Why is OracleDataAdapter.Fill() Very Slow?

  - by John Gietzen

  I am using a pretty complex query to retrieve some data out of one of our billing databases. I'm running in to an issue where the query seems to complete fairly quickly when executed with SQL Developer, but does not seem to ever finish when using the OracleDataAdapter.Fill() method. I'm only trying to read about 1000 rows, and the query completes in SQL Developer in about 20 seconds. What could be causing such drastic differences in performance? I have tons of other queries that run quickly using the same function. Here is the code I'm using to execute the query: using Oracle.DataAccess.Client; ... public DataTable ExecuteExternalQuery(string connectionString, string providerName, string queryText) { DbConnection connection = null; DbCommand selectCommand = null; DbDataAdapter adapter = null; switch (providerName) { case "System.Data.OracleClient": case "Oracle.DataAccess.Client": connection = new OracleConnection(connectionString); selectCommand = connection.CreateCommand(); adapter = new OracleDataAdapter((OracleCommand)selectCommand); break; ... } DataTable table = null; try { connection.Open(); selectCommand.CommandText = queryText; selectCommand.CommandTimeout = 300000; selectCommand.CommandType = CommandType.Text; table = new DataTable("result"); table.Locale = CultureInfo.CurrentCulture; adapter.Fill(table); } finally { adapter.Dispose(); if (connection.State != ConnectionState.Closed) { connection.Close(); } } return table; } And here is the general outline of the SQL I'm using: with trouble_calls as ( select work_order_number, account_number, date_entered from work_orders where date_entered >= sysdate - (15 + 31) -- Use the index to limit the number of rows scanned and wo_status not in ('Cancelled') and wo_type = 'Trouble Call' ) select account_number, work_order_number, date_entered from trouble_calls wo where wo.icoms_date >= sysdate - 15 and ( select count(*) from trouble_calls repeat where wo.account_number = repeat.account_number and wo.work_order_number <> repeat.work_order_number and wo.date_entered - repeat.date_entered between 0 and 30 ) >= 1

• 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?

• UIView rotation, modal view lanscape and portrait, parent fails to render

  - by Ben

  Hi everyone, I've hit a bit of a roadblock with something that I hope that someone in here can help me out with. I'll describe the 'state of play' first, and then what the issue is, so here goes; I have a series of view controllers that are chained together with a Navigation Controller (this works just fine), All of these view controllers support portrait mode only (by design), In one of the view controllers (the 'end' one actually) the user can click a table cell to pop up a modal view controller (using presentModalViewController(...) of course) This modal view controller supports portrait and landscape modes (and this works), When the user clicks the 'Done' button on this modal view controller we pop and pass control back to the parent view controller, however; If the user is in portrait mode when they click 'Done' then the parent displays itself just fine, If the user is in landscape mode when they click 'Done' then the parent displays a totally white, blank screen (that covers the whole screen). It is as if the controller does not know how to render in landscape and just doesn't bother. I'd like to be able to have this parent view render in portrait no matter what the orientation of the phone is when the user clicks the 'Done' button. Various forum posts suggest using the UIDevice method 'setOrientation' (but this is undocumented and will get our app rejected apparently). Another suggestion was to set the 'statusBarOrientation' to portrait in the 'viewWillAppear' method but that had no effect. So I am a bit stuck! Has any encountered anything like this before? If need be I can provide code, if that will help anyone diagnose the problem for me. Thanks in advance! Cheers, Ben

• Problem resolving a generic Repository with Entity Framework and Castle Windsor Container

  - by user368776

  Hi, im working in a generic repository implementarion with EF v4, the repository must be resolved by Windsor Container. First the interface public interface IRepository<T> { void Add(T entity); void Delete(T entity); T Find(int key) } Then a concrete class implements the interface public class Repository<T> : IRepository<T> where T: class { private IObjectSet<T> _objectSet; } So i need _objectSet to do stuff like this in the previous class public void Add(T entity) { _objectSet.AddObject(entity); } And now the problem, as you can see im using a EF interface like IObjectSet to do the work, but this type requires a constraint for the T generic type "where T: class". That constrait is causing an exception when Windsor tries to resolve its concrete type. Windsor configuration look like this. <castle> <components> <component id="LVRepository" service="Repository.Infraestructure.IRepository`1, Repository" type="Repository.Infraestructure.Repository`1, Repository" lifestyle="transient"> </component> </components> The container resolve code IRepository<Product> productsRep =_container.Resolve<IRepository<Product>>(); Now the exception im gettin System.ArgumentException: GenericArguments[0], 'T', on 'Repository.Infraestructure.Repository`1[T]' violates the constraint of type 'T'. ---> System.TypeLoadException: GenericArguments[0], 'T', on 'Repository.Infraestructure.Repository`1[T]' violates the constraint of type parameter 'T'. If i remove the constraint in the concrete class and the depedency on IObjectSet (if i dont do it get a compile error) everything works FINE, so i dont think is a container issue, but IObjectSet is a MUST in the implementation. Some help with this, please.

• Integrating PartCover.NET with NAnt

  - by davandries

  Hello, I'm trying to integrate PartCover.NET with NAnt and CruiseControl.NET I can run PartCover.NET browser without problems, but it does not work once I try to run it in an NAnt task (in my CCNET build). There must be an issue with my NAnt target but I can't find it. Maybe someone had experienced the same issues in the past?. <target name="CoverageUnitTest" description="Code coverage of unit tests"> <exec program="${PartCover.exe}"> <arg value="--target=${NUnit.console}" /> <arg value="--target-work-dir=${project.dir}\bin\${configuration}"/> <arg value="--target-args=${project}.dll" /> <arg value="--output=C:\partcover.xml" /> <arg value="--include=[*]*" /> </exec> </target> In CruiseControl, I got the following error message: [exec] Invalid option '--target C:\NUnit\bin\nunit-console.exe' Build Error: NAnt.Core.BuildException External Program Failed: C:\PartCover\PartCover.exe (return code was -1) in C:\default.build line: 20 col: 4 at NAnt.Core.Tasks.ExternalProgramBase.ExecuteTask() at NAnt.Core.Tasks.ExecTask.ExecuteTask() at NAnt.Core.Task.Execute() at NAnt.Core.Target.Execute() at NAnt.Core.Project.Execute(String targetName, Boolean forceDependencies) at NAnt.Core.Project.Execute() at NAnt.Core.Project.Run() thanks !

• CKEditor instance already exists

  - by jackboberg

  I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load. When the user cancels the dialog, I am removing the contents so that they are loaded fresh on a later request. The issue is, once the dialog is reloaded, the CKEditor claims the editor already exists. uncaught exception: [CKEDITOR.editor] The instance "textarea_name" already exists. The API includes a method for destroying existing editors, and I have seen people claiming this is a solution: if (CKEDITOR.instances['textarea_name']) { CKEDITOR.instances['textarea_name'].destroy(); } CKEDITOR.replace('textarea_name'); This is not working for me, as I receive a new error instead: TypeError: Result of expression 'i.contentWindow' [null] is not an object. This error seems to occur on the "destroy()" rather than the "replace()". Has anyone experienced this and found a different solution? Is is possible to 're-render' the existing editor, rather than destroying and replacing it? UPDATED Here is another question dealing with the same problem, but he has provided a downloadable test case.

  I have researched my issue all over StackOverflow and multi-google links, and I am still confused. I figured the best thing for me is ask... Im creating a simple command line calculator. Here is my code so far: const std::string Calculator::SIN("sin"); const std::string Calculator::COS("cos"); const std::string Calculator::TAN("tan"); const std::string Calculator::LOG( "log" ); const std::string Calculator::LOG10( "log10" ); void Calculator::set_command( std::string cmd ) { for(unsigned i = 0; i < cmd.length(); i++) { cmd[i] = tolower(cmd[i]); } command = cmd; } bool Calculator::is_legal_command() const { switch(command) { case TAN: case SIN: case COS: case LOG: case LOG10: return true; break; default: return false; break; } } the error i get is: Calculator.cpp: In member function 'bool Calculator::is_trig_command() const': Calculator.cpp: error: switch quantity not an integer Calculator.cpp: error: 'Calculator::TAN' cannot appear in a constant-expression Calculator.cpp: error: 'Calculator::SIN' cannot appear in a constant-expression Calculator.cpp: error: 'Calculator::COS' cannot appear in a constant-expression The mighty internet, it says strings are allowed to be used in switch statements.

• "Unable To Load Client Print Control" - SSRS Printing problems again

  - by mamorgan1

  Please forgive me as my head is spinning. I have tried so many solutions to this issue, that I'm almost not sure where I am at this point. At this point in time I have these issues in my Production, Test, and Dev environments. For simplicity sake, I will just try to get it working in Dev first. Here is my setup: Database/Reporting Server (Same server): Windows Server 2003 SP2 SQL Server 2005 SP3 Development Box: Windows 7 Visual Studio 2008 SP1 SQL Server 2008 SP1 (not being used in this case, but wanted to include it in case it is relative) Internet Explorer 8 Details: * I have a custom ASP.NET application that is using ReportViewer to access reports on my Database/Reporting Server. * I am able to connect directly to Report Manager and print with no trouble. * When I view source on the page with ReportViewer, it says I'm am using version 9.0.30729.4402 . * The classid of the rsclientprint.dll that keeps getting installed to my c:\windows\downloaded program files directory is {41861299-EAB2-4DCC-986C-802AE12AC499}. * I have tried taking the rsclientprint.cab file from my Database/Reporting Server and installing it directly to my Development Box and had no success. I made sure to unregister the previously installed dll first. I feel like I have read as many solutions as I can, and so I turn to you for some assistance. Please let me know if I can provide further details that would be helpful. Thanks

• Need advice or pointers on Release Management Strategies

  - by Murray

  I look after an internal web based (Java, JSP, Mediasurface, etc.) system that is in constant use (24/5). Users raise tickets for enhancements, bug fixes and other business changes. These issues are signed off individually and assigned to one of three or four developers. Once the issue is complete it is built and the code only committed to SVN. The changed files (templates, html, classes, jsp) are then copied to a dev server and committed to a different repository from where they are checked out to the UAT server for testing. (this often requires the Tomcat service to be restarted and occasionally the Mediasurface service as well). The users then test and either reject or approve the release. If approved the edited files are checked out to the Live server and the same process as with UAT undertaken. If rejected the developer makes the relevant changes and starts the release process again. This is all done manually without much control. Where different developers are working on similar files, changes sometimes get overwritten by builds done on out of sync code in other cases changes in UAT are moved to live in error as they are mixed up in files associated with a signed off release. I would like to move this to a more controlled and automated process where all source code and output files are held in SVN and releases to Dev, UAT and Live managed by a CI system (We have TeamCity in house for our .NET applications). My question is on how to manage the releases of multiple changes where some will be signed off and moved on and others rejected and returned to the developer. The changes may be on overlapping files and simply merging each release in to a Release Branch means that the rejected changes would have to be backed out of the branch. Is there a way to manage this using SVN and CI or will I simply have to live with the current system.

• 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.

• How do I get SSIS Data Flow to put '0.00' in a flat file?

  - by theog

  I have an SSIS package with a Data Flow that takes an ADO.NET data source (just a small table), executes a select * query, and outputs the query results to a flat file (I've also tried just pulling the whole table and not using a SQL select). The problem is that the data source pulls a column that is a Money datatype, and if the value is not zero, it comes into the text flat file just fine (like '123.45'), but when the value is zero, it shows up in the destination flat file as '.00'. I need to know how to get the leading zero back into the flat file. I've tried various datatypes for the output (in the Flat File Connection Manager), including currency and string, but this seems to have no effect. I've tried a case statement in my select, like this: CASE WHEN columnValue = 0 THEN '0.00' ELSE columnValue END (still results in '.00') I've tried variations on that like this: CASE WHEN columnValue = 0 THEN convert(decimal(12,2), '0.00') ELSE convert(decimal(12,2), columnValue) END (Still results in '.00') and: CASE WHEN columnValue = 0 THEN convert(money, '0.00') ELSE convert(money, columnValue) END (results in '.0000000000000000000') This silly little issue is killin' me. Can anybody tell me how to get a zero Money datatype database value into a flat file as '0.00'?

• SVG animation along path with Raphael

  - by Toby Hede

  I have a rather interesting issue with SVG animation. I am animating along a circular path using Raphael obj = canvas.circle(x, y, size); path = canvas.circlePath(x, y, radius); path = canvas.path(path); //generate path from path value string obj.animateAlong(path, rate, false); The circlePath method is one I have created myself to generate the circle path in SVG path notation: Raphael.fn.circlePath = function(x , y, r) { var s = "M" + x + "," + (y-r) + "A"+r+","+r+",0,1,1,"+(x-0.1)+","+(y-r)+" z"; return s; } So far, so good. This all works. I have my object (obj) animating along the circular path. BUT: The animation only works if I create the object at the same X, Y coords as the path itself. If I start the animation from any other coordinates (say, half-way along the path) the object animates in a circle of the correct radius, however it starts the animation from the object X,Y coordinates, rather than along the path as it is displayed visually. Ideally I would like to be able to stop/start the animation - the same problem occurs on restart. When I stop then restart the animation, it animates in a circle starting from the stopped X,Y.

• Does Android XML Layout's 'include' Tag Really Work?

  - by Eric Burke

  I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)" Since Romain indicates this works in the test suites and his examples, I must be doing something wrong. My project is organized like this: res/layout buttons.xml res/layout-land receipt.xml res/layout-port receipt.xml The buttons.xml contains something like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <Button .../> <Button .../> </LinearLayout> And the portrait and landscape receipt.xml files look something like: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> ... <!-- Overridden attributes never work. Nor do attributes like the red background, which is specified here. --> <include android:id="@+id/buttons_override" android:background="#ff0000" android:layout_width="fill_parent" layout="@layout/buttons"/> </LinearLayout> What am I missing?

• Visual Studio 2010 Can no longer build .NET v3.5

  - by Adam Driscoll

  I have a 2010 project that is targeting .NET v3.5. Inexplicably I can no longer build v3.5 projects. The project doesn't have ANY references added. It won't even let me add a reference to System.Core as it is added by the 'build system'. warning CS1685: The predefined type 'System.Func' is defined in multiple assemblies in the global alias; using definition from 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' IFilter.cs(82,49): error CS0433: The type 'System.Func' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll' and 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' Looks like something is grabbing onto 4.0 but I'm not quite sure how to fix it. Any one else run into this? Coworker had this same issue. It took a reinstall of Windows to correct the problem I've opened a bug on this one: https://connect.microsoft.com/VisualStudio/feedback/details/558245/warning-cs1685-when-compiling-a-v3-5-net-application-in-visual-studio-2010 If the compiler is set to verbose I see this: FrameworkPathOverride = C:\Windows\Microsoft.NET\Framework\v4.0.30319 which is defined as: Specifies the location of mscorlib.dll and microsoft.visualbasic.dll.

I can build 2.0, 3.0, 3.5 Client Profile, 4.0 and 4.0 Client Profile with no problem. VB.NET can build v3.5 but C# cannot. I've tried a reinstall of .NET 3.5, 4.0 and Visual Studio 2010 with no success. Visual Studio debug logs shown nothing interesting and Safe Mode does not work. Trying to avoid a Windows reinstall...

• Static IP for dynamic IP

  - by scape279

  I have a dynamic IP address. I would like to have a static IP, but Virgin Media don't allow static IPs for residential broadband services, even if you ask them really nicely and offer to pay for it without switching to a business tariff. I am already registered with a dynamic DNS service which is updated by my router eg me.example.com will always resolve to my dynamic IP. This is fine for some circumstances, but not if you can only enter an IP address into configuration files/hardware etc like firewalls, subversion services etc etc. Is there a way I can have a static IP address 'forwarding' to my dynamic IP? Would a possible solution involve tunnelling? Setting up a private proxy? Please note the following: I am able to buy an IP address from my web host. I have access to a webserver and I am able to create custom DNS zones. I'm happy to have a webserver running at home if necessary also. I do not wish to change broadband providers. I have zero control over the services that require the IP address entering so I cannot tackle the problem that way round (services I need to access are at work). PS I've tried googling this issue, but it is very difficult to search for as most results are related to dynamic dns (which I already have set up and isnt quite what I'm after)

• malloc: error checking and freeing memory

  - by yCalleecharan

  Hi, I'm using malloc to make an error check of whether memory can be allocated or not for the particular array z1. ARRAY_SIZE is a predefined with a numerical value. I use casting as I've read it's safe to do so. long double *z1 = (long double *)malloc(sizeof (long double) * ARRAY_SIZE); if(z1 == NULL){ printf("Out of memory\n"); exit(-1); } The above is just a snippet of my code, but when I add the error checking part (contained in the if statement above), I get a lot of compile time errors with visual studio 2008. It is this error checking part that's generating all the errors. What am I doing wrong? On a related issue with malloc, I understand that the memory needs to be deallocated/freed after the variable/array z1 has been used. For the array z1, I use: free(z1); z1 = NULL; Is the second line z1 = NULL necessary? Thanks a lot...

• sqlalchemy date type in 0.6 migration using mssql

  - by nosklo

  I'm connection to mssql server through pyodbc, via FreeTDS odbc driver, on linux ubuntu 10.04. Sqlalchemy 0.5 uses DATETIME for sqlalchemy.Date() fields. Now Sqlalchemy 0.6 uses DATE, but sql server 2000 doesn't have a DATE type. How can I make DATETIME be the default for sqlalchemy.Date() on sqlalchemy 0.6 mssql+pyodbc dialect? I'd like to keep it as clean as possible. Here's code to reproduce the issue: import sqlalchemy from sqlalchemy import Table, Column, MetaData, Date, Integer, create_engine engine = create_engine( 'mssql+pyodbc://sa:sa@myserver/mydb?driver=FreeTDS') m = MetaData(bind=engine) tb = sqlalchemy.Table('test_date', m, Column('id', Integer, primary_key=True), Column('dt', Date()) ) tb.create() And here is the traceback I'm getting: Traceback (most recent call last): File "/tmp/teste.py", line 15, in <module> tb.create() File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/schema.py", line 428, in create bind.create(self, checkfirst=checkfirst) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1647, in create connection=connection, **kwargs) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1682, in _run_visitor **kwargs).traverse_single(element) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/sql/visitors.py", line 77, in traverse_single return meth(obj, **kw) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/ddl.py", line 58, in visit_table self.connection.execute(schema.CreateTable(table)) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1157, in execute params) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1210, in _execute_ddl return self.__execute_context(context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1268, in __execute_context context.parameters[0], context=context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1367, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/base.py", line 1360, in _cursor_execute context) File "/home/nosklo/.local/lib/python2.6/site-packages/sqlalchemy/engine/default.py", line 277, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.ProgrammingError: (ProgrammingError) ('42000', '[42000] [FreeTDS][SQL Server]Column or parameter #2: Cannot find data type DATE.

• Why is software quality so problematic?

  - by Yuval A

  Even when viewing the subject in the most objective way possible, it is clear that software, as a product, generally suffers from low quality. Take for example a house built from scratch. Usually, the house will function as it is supposed to. It will stand for many years to come, the roof will support heavy weather conditions, the doors and the windows will do their job, the foundations will not collapse even when the house is fully populated. Sure, minor problemsdo occur, like a leaking faucet or a bad paint job, but these are not critical. Software, on the other hand is much more susceptible to suffer from bad quality: unexpected crashes, erroneous behavior, miscellaneous bugs, etc. Sure, there are many software projects and products which show high quality and are very reliable. But lots of software products do not fall in this category. Take into consideration paradigms like TDD which its popularity is on the rise in the past few years. Why is this? Why do people have to fear that their software will not work or crash? (Do you walk into a house fearing its foundations will collapse?) Why is software - subjectively - so full of bugs? Possible reasons: Modern software engineering exists for only a few decades, a small time period compared to other forms of engineering/production. Software is very complicated with layers upon layers of complexity, integrating them all is not trivial. Software development is relatively easy to start with, anyone can write a simple program on his PC, which leads to amateur software leaking into the market. Tight budgets and timeframes do not allow complete and high quality development and extensive testing. How do you explain this issue, and do you see software quality advancing in the near future?

• Cannot access updated Java object from Saxon XSLT processor

  - by chipk

  I am working with an open source version of the Saxon XSLT processor "Saxon 9.0.0.2J from Saxonica" and am trying to make use of the java extensibility for the first time. I am running into an issue I suspect may be a limitation on the open source version, but wanted to check first whether there might be something I am just missing here. From the snippet below, my result is that the final value of $c1 does not change as a result of the call to greg:setTime() - i.e. the $c1 variable within Saxon appears to be unhooked from the underlying Java object and there is no apparent way to access the object as updated by the setTime() call. NOTE that all code in the snippet is tested and working otherwise - i.e. $c1 is properly instantiated by the getInstance() call, $startdate is of the proper format and $d1 is properly instantiated. Thoughts? <xsl:transform ..... xmlns:sql="java:java.sql.Date" xmlns:greg="java:java.util.GregorianCalendar" ..... > .... <xsl:element name="JobExpireDate"> <xsl:variable name="c1" select="greg:getInstance()" /> <xsl:variable name="d1" select="sql:valueOf($startdate)" /> <xsl:variable name="void" select="greg:setTime($c1,$d1)" /> <xsl:value-of select="$c1" /> </xsl:element>

• jQuery animating scroll top to 0 not working on Windows Phone

  - by cgoddard

  I have written a website which has a function that scrolls the users view to the top of the page. The call in question is: $('html,body').animate({scrollTop:0}, 150, 'swing'); This works fine on all desktop browsers, but on Windows Phone, it only scrolls the user up about 180 pixels, then stops. I have tried replacing the function with: $('html,body').scrollTop(0); It snaps to the top on desktops, but it scrolls to the top on the phone. I believe this need for Internet Explorer Mobile to try to smoothly animate the scrolling, and is causing the issue. If this is the case (or if not, could someone correct me), how can I override this function to get the animation to work? EDIT Although its not ideal, it does seem to work in a limited capacity, I have replaced the scroll code with this: $('html,body').animate({scrollTop:0}, 150, 'swing', function() { $('html,body').scrollTop(0); }); But it would be good to know if there is an option to disable the smooth scrolling in Mobile IE programatically.

• ASP.NET MVC Session Expiration

  - by Andrew Flanagan

  We have an internal ASP.NET MVC application that requires a logon. Log on works great and does what's expected. We have a session expiration of 15 minutes. After sitting on a single page for that period of time, the user has lost the session. If they attempt to refresh the current page or browse to another, they will get a log on page. We keep their request stored so once they've logged in they can continue on to the page that they've requested. This works great. However, my issue is that on some pages there are AJAX calls. For example, they may fill out part of a form, wander off and let their session expire. When they come back, the screen is still displayed. If they simply fill in a box (which will make an AJAX call) the AJAX call will return the Logon page (inside of whatever div the AJAX should have simply returned the actual results). This looks horrible. I think that the solution is to make the page itself expire (so that when a session is terminated, they automatically are returned to the logon screen without any action by them). However, I'm wondering if there are opinions/ideas on how best to implement this specifically in regards to best practices in ASP.NET MVC.

• Pre Commit Hook for JSLint in Mercurial and Git

  - by jrburke

  I want to run JSLint before a commit into either a Mercurial or Git repo is done. I want this as an automatic step that is set up instead of relying on the developer (mainly me) remembering to run JSLint before-hand. I normally run JSLint while developing, but want to specify a contract on JS files that they pass JSLint before being committed to the repo. For Mercurial, this page spells out the precommit syntax, but the only variables that seem to be available are the parent1 and parent2 changeset IDs involved in the commit. What I really want are a list of file names that are involved with the commit, so that I can then choose the .js file and run jslint over them. Similar issue for GIT, the default info available as part of the precommit script seems limited. What might work is calling hg status/git status as part of the precommit script, parse that output to find JS files then do the work that way. I was hoping for something easier though, and I am not sure if calling status as part of a precommit hook reflect the correct information. For instance in Git if the changes files have not been added yet, but the git commit uses -a, would the files show up in the correct section of the git status output as being part of the commit set? Update: I got something working, it is visible here: http://github.com/jrburke/dvcs_jslint/
