• Handling changes in column order when importing CSV files

  - by Scott

  I have a CSV file. The first row will always contain column headers. Depending on a variety of factors, the order of columns may change and, in rare circumstances, some columns may not be present. These changes are beyond my control. My thoughts, so far, on how to address this. I'll read the first row of the file and use the values to generate a list of columns contained in the source file. The destination file will use the same column names as the source. This should be as simple as searching for identical names in the source and destination, then just mapping the column index values, right? What are your recommendations for handling this?

• Why does setting a form's enabled property crash the application?

  - by Ruirize

  private void launchbutton_Click(object sender, EventArgs e) { launchbutton.Enabled = false; Process proc = new Process(); proc.EnableRaisingEvents = true; proc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; //The arguments/filename is set here, just removed for privacy. proc.Exited += new EventHandler(procExit); proc.Start(); } private void procExit(object sender, EventArgs e) { MessageBox.Show("YAY","WOOT"); Thread.Sleep(2000); launchbutton.Enabled = true; } 2 Seconds after I quit the created process, my program crashes. Why?

• relating data stored in NoSQL DB to data stored in SQL DB

  - by seanbrant

  Whats the best way to use a SQL DB along side a NoSQL DB? I want to keep my users and other data in postgres but have some data that would be better suited for a NoSQL DB like redis. I see a lot of talk about switching to NoSQL but little talk on integrating it with existing systems. I think it would be foolish to throw the baby out with the bath water and ditch SQL all together, unless it makes things easier to maintain and develop. I'm wondering what the best approach is for relating data stored in SQL to my data in redis. I was thinking of something along the line of this. User object stored in SQL Book object in redis, key sh1 hash of value, value is a JSON string Relations stored in redis, key User.pk:books, value redis set of sha1's Anyone have experience, tips, better ways?

• Mono 2.10.5 Runtime error on Ubuntu 11.10

  - by johnluetke

  I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

• Grails unit testing domain classes with Set properties - is this safe?

  - by Ali G

  I've created a domain class in Grails like this: class MyObject { static hasMany = [tags: String] // Have to declare this here, as nullable constraint does not seem to be honoured Set tags = new HashSet() static constraints = { tags(nullable: false) } } Writing unit tests to check the size and content of the MyObject.tags property, I found I had to do the following: assertLength(x, myObject.tags as Object[]) assertEquals(new HashSet([...]), myObject.tags) To make the syntax nicer for writing the tests, I implemented the following methods: void assertEquals(List expected, Set actual) { assertEquals(new HashSet(expected), actual) } void assertLength(int expected, Set set) { assertLength(expected, set as Object[]) } I can now call the assertLength() and assertEquals() methods directly on an instance of Set, e.g. assertLength(x, myObject.tags) assertEquals([...], myObject.tags) I'm new to Groovy and Grails, so unaware how dangerous method overloading like this is. Is it safe? If so, I'm slightly* surprised that these methods (or similar) aren't already available - please let me know if they are. * I can see how these methods could also introduce ambiguity if people weren't expecting them. E.g. assertLength(1, set) always passes, no matter what the content of set

• Why people do not like OOP? [closed]

  - by Gabriel Šcerbák

  I do not understand why people choose C++ over Smalltalk in past and why Java over Python or Ruby. What is it that ties people so much to the procedural programming and makes it so difficult to go "all the way" to object oriented programming? What makes OOP hard? Should not objects be an abstraction which is easier to grasp for people, i.e. a more natural one than procedures? Is education the problem (because people tend to learn procedural programming before object oriented)?

• Changing Pushpin Text Color

  - by Yawus

  I'm attempting to display data through the text of a Pushpin object. However, the text color defaults to white which is nigh-invisible when the backdrop is a road-style MapView. Looking through the API, paying especially close attention to PushpinOptions, I couldn't find anything that manipulated text color. Considering that this seems to a fairly basic feature, I'm a little confused as to why it doesn't exist or at least is really hard to find. Am I missing something or does Bing Maps for Android really not let you change the default text color for a Pushpin object?

• Why does this VBS scheduled task (to call a URL) not work in Windows Server 2008?

  - by user303644

  This same script worked in older server OS environments, and even on my desktop; and allows me to kick off a nightly process on my website's URL. It simply will not execute the URL in my Windows Server 2008 environment. It does not generate any errors, claiming task completion I can pull the same URL up just fine in the server's web browser I have the script running with "highest privileges" I even tried to create a batch file which executes it, so I can explicitly "Run as Administrator" and it still will not execute the URL (but will not generate any errors either). I'm baffled as to why the task claims to have completed successfully, yet the script never reaches the URL. Call LogEntry() Sub LogEntry() 'Force the script to finish on an error. On Error Resume Next 'Declare variables Dim objRequest Dim URL Set objRequest = CreateObject("MSXML2.ServerXMLHTTP") 'Put together the URL link appending the Variables. URL = "http://myURL/AutorunNightlyTasks.aspx" 'Open the HTTP request and pass the URL to the objRequest object objRequest.open "GET", URL, False 'Send the HTML Request objRequest.send() 'Set the object to nothing Set objRequest = Nothing End Sub

• HQL - row identifier for pagination

  - by anna.ruk

  Does anyone know if HQL has a keyword to identify rows such as ROWID or ROWNUM? I would like to implement pagination with HQL but I am not able to use .setMaxResult() or .setFirstResult() because I don't work with the session object directly and therefore don't use the Query object but simply create my query as a string and use the .find() method. I tried using LIMIT and OFFSET in my query, but HQL seems to be ignoring these keywords and is returning the whole result to me no matter what. I'm also not able to use Hibernate criteria because it does not have support for the "HAVING" clause that appears in my query. My last resort is to restrict the result set using the ROWNUM/ROWID keyword. Does anyone else have any other suggestions?

• NHibernate 3 and MySQL setup tutorial

  - by ryanzec

  Since I have given up on using the entity framework 4 as my ORM (getting it to work with MySQL and mapping table/field names like this_table/this_field to object naming like ThisTable/ThisField is POCO) I am now looking at NHibernate as it seems the the next big well know ORM for C# that probably with not die off any time soon. I am trying to lookup some tutorials and a lot of them in the configuration section have 2-2 in it and was wondering if those configuration would work with NHibernate 3? I am just curious if the 2-2 refers to the version of NHibernate or something different.

• How do I compile on linux to share with all distributions?

  - by Andrew M

  I compiled a PHP extension on Fedora Core 12, but when I send it to someone using CentOS they get the error: "ELF file OS ABI invalid" I'm not sure what causes this running file provides the following info: ELF 64-bit LSB shared object, AMD x86-64, version 1 (GNU/Linux), not stripped An extension that loads fine provides the following from file: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped So it seems I need to generate a SYSV type file for some distributions, instead of a GNU/LINUX file, no idea how though. Any pointers? Also should I be statically linking?

• Is calling of overload operator-> resolved at compile time?

  when I tried to compile the code: (note: func and func2 is not typo) struct S { void func2() {} }; class O { public: inline S* operator->() const; private: S* ses; }; inline S* O::operator->() const { return ses; } int main() { O object; object->func(); return 0; } there is a compile error reported: D:\code>g++ operatorp.cpp -S -o operatorp.exe operatorp.cpp: In function `int main()': operatorp.cpp:27: error: 'struct S' has no member named 'func' it seems that invoke the overloaded function of "operator-" is done during compile time? I'd added "-S" option for compile only.

• How to run lengthy tasks from an ASP.NET page?

  - by Jimmy C

  I've got an ASP.NET page with a simple form. The user fills out the form with some details, uploads a document, and some processing of the file then needs to happens on the server side. My question is - what's the best approach to handling the server side processing of the files? The processing involves calling an exe. Should I use seperate threads for this? Ideally I want the user to submit the form without the web page just hanging there while the processing takes place. I've tried this code but my task never runs on the server: Action<object> action = (object obj) => { // Create a .xdu file for this job string xduFile = launcher.CreateSingleJobBatchFile(LanguagePair, SourceFileLocation); // Launch the job launcher.ProcessJob(xduFile); }; Task job = new Task(action, "test"); job.Start(); Any suggestions are appreciated.

• HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

  - by Julian de Wit

  Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

• How do I render a partial to a string from within a filter attached to a controller

  - by Tristan Havelick

  I have some code I need to use in multiple controllers in a rails 1.0 application (I can't, for strange reasons upgrade to a newer rails). I've extracted the relevant code into a filer object, and I'm using the around_filter construct to execute it. Before the extract, I was using the method render_to_string() to get the contents of a rendered partial into a string. However, this method is protected, so I am unable to access it from within my Filter object. As a workaround, I tried adding this to my ApplicationController: def render_to_string(*a) super(*a) end this seems to have remedied the protection level issue, but now I get the error: Can only render or redirect once per action When no such error occurred before the extraction. Why? Is there a different approach I should take here?

• Pure virtual destructor in interface

  - by ALOR

  Hello all. Here is my problem. I'm making C++ dll, which extensively relies on instance object exports. So i return my actual instances as a pointers to interface through some exported factory method. Interfaces i use are purely virtual, to avoid linking problame. So i need a pure virtual destructor too, and i implemented one (with empty body, as i googled it). All compiles perfectly well, except... I can't see, if the actual destructors are called or not - because when i added some std::cout << "hello destructor"; i never get to see it. I have some explicit "delete obj", that's not the problem. Am i missing something? Is there another way to delete my object through interface?

• Merge two lists of objects which hold different data

  - by C.McAtackney

  I have an object "Project" which has a number of fields, one of which is "Name". I have one spreadsheet of projects which contains some of these fields, and another which contains the rest. However, Both spreadsheets have the "Name" field. I've read them in and populated two List, only populating the available fields from that particular source. E.g. a Project from List 1 looks like; {Name="MyProj", Type="Form", Priority=NULL}, whereas a Project from List 2 {Name="MyProj", Type=NULL, Priority="High"}. Now, I want to merge these two lists into one in which each Project object has all of its fields populated, with the Name field being used to match the elements. How can I achieve this? Are there any nice ways of doing this concisely? Thanks

• How can I "override" deepcopy in Python?

  - by Az

  Hi there, I'd like to override __deepcopy__ for a given SQLAlchemy-mapped class such that it ignores any SQLA attributes but deepcopies everything else that's part of the class. I'm not particularly familiar with overriding any of Python's built-in objects in particular but I've got some idea as to what I want. Let's just make a very simple class User that's mapped using SQLA. class User(object): def __init__(self, user_id, name): self.user_id = user_id self.name = name I've used dir() to see, before and after mapping, what SQLAlchemy-specific attributes there are and I've found _sa_class_manager and _sa_instance_state. Provided those are the only ones how would I ignore that when defining __deepcopy__? Also, are there any attributes the SQLA injects into the mapped object? (I asked this in a previous question (as an edit a few days after I selected an answer to the main question, though) but I think I missed the train there. Apologies for that.)

I am just receiving null exception. So in other word I try to explain the situation: when I load my page I am initializing some parameter. then everything is working fine. in my page when I change selected item of my combo box, page suppose to go and run function related to that combo box, and call page_load, but it is not going there and it goes to rowcreated function.

• How to detect crashing tabed webbrowser and handle it?

  - by David Eaton

  I have a desktop application (forms) with a tab control, I assign a tab and a new custom webrowser control. I open up about 10 of these tabs. Each one visits about 100 - 500 different pages. The trouble is that if 1 webbrowser control has a problem it shuts down the entire program. I want to be able to close the offending webbrowser control and open a new one in it's place. Is there any event that I need to subscribe to catch a crashing or unresponsive webbrowser control ? I am using C# on windows 7 (Forms), .NET framework v4 =============================================================== UPDATE: 1 - The Tabbed WebBrowser Example Here is the code I have and How I use the webbrowser control in the most basic way.

Using the answer below by mo. , you can surf the first url with no problem, but what about all the urls the user clicks on? How do we check those? I prefer not to add events to every single html element on a page, there has to be a way to run the new urls thru the function OpenUrl before it navigates without having an endless loop. Thanks.

• Treating a fat webservice in .net 3.5 c#

  - by Chris M

  I'm dealing with an obese 3rd party webservice that returns about 3mb of data for a simple search results, about 50% of the data in that response is junk. Would it make sense then to remap this data to my own result object and ditch the response so I'm storing 1-2 mb in memory for filtering and sorting rather than using the web-responses own object and using 2-4 or am I missing a point? So far I've been accessing the webservice from a separate project and using a new class to provide the interaction and to handle the persistence so my project looks like this |- Web (mvc2 proj) |- DAL (database/storage fluent-nhibernate) |- SVCGateway (interaction layer + webservice related models) |- Services -------------- |- Tests |- Specs I'm trying to make the application behave fast and I also need to store the result set temporarily in case a customer goes to view the product and wants to go back to the results. (Service returns only 500 of possible 14K results). So basically I'm looking for confirmation that I'm doing the right thing in pushing the results into my own objects or if I'm breaking some rule or even if there's a better way of handling it. Thanks

• Casting objects in C# (ASP.Net MVC)

  - by Mortanis

  I'm coming from a background in ColdFusion, and finally moving onto something modern, so please bear with me. I'm running into a problem casting objects. I have two database tables that I'm using as Models - Residential and Commercial. Both of them share the majority of their fields, though each has a few unique fields. I've created another class as a container that contains the sum of all property fields. Query the Residential and Commercial, stuff it into my container, cunningly called Property. This works fine. However, I'm having problems aliasing the fields from Residential/Commercial onto Property. It's quite easy to create a method for each property: fillPropertyByResidential(Residential source) and fillPropertyByCommercial(Commercial source), and alias the variables. That also works fine, but quite obviously will copy a bunch of code - all those fields that are shared between the two main Models. So, I'd like a generic fillPropertyBySource() that takes the object, and detects if it's Residential or Commercial, fills the particular fields of each respective type, then do all the fields in common. Except, I gather in C# that variables created inside an If are only in the scope of the if, so I'm not sure how to do this. public property fillPropertyBySource(object source) { property prop = new property(); if (source is Residential) { Residential o = (Residential)source; //Fill Residential only fields } else if (source is Commercial) { Commercial o = (Commercial)source; //Fill Commercial only fields } //Fill fields shared by both prop.price = (int)o.price; prop.bathrooms = (float)o.bathrooms; return prop; } "o" being a Commercial or Residential only exists within the scope of the if. How do I detect the original type of the source object and take action? Bear with me - the shift from ColdFusion into a modern language is pretty..... difficult. More so since I'm used to procedural code and MVC is a massive paradigm shift. Edit: I should include the error: The name 'o' does not exist in the current context For the aliases of price and bathrooms in the shared area.
