• Detecting if Excel file has been closed

  - by Charlie

  Hi StackOverflow, I've spent the past 3 hours trawling the web for answers to no avail, so I hope you can help me. I'm writing an application which automates Excel. The application has an option to "show/hide the excel sheet" so you can look at it, make any final changes and so forth. Closing the application will naturally close the instance of Excel, however, there is a small chance that someone may exit out of Excel directly, without thinking. This breaks my application and I can't seem to find anyway of "checking if the same workbook is still open, and if not, re-opening it", before saving it I've tried all sorts of things: checking if the Excel Application is null (when it's !=null it will save correctly, but when it "is" null (or at least, something other than !=null it won't even hit the breakpoint so I'm completely lost :( Help please?

• Linq to SQL Where clause based on field selected at runtime

  - by robasaurus

  I'm trying to create a simple reusable search using LINQ to SQL. I pass in a list of words entered in a search box. The results are then filtered based on this criteria. private IQueryable<User> BasicNameSearch(IQueryable<User> usersToSearch, ICollection<string> individualWordsFromSearch) { return usersToSearch .Where(user => individualWordsFromSearch.Contains(user.Forename.ToLower()) || individualWordsFromSearch.Contains(user.Surname.ToLower())); } Now I want this same search functionality on a different datasource and want to dynamically select the fields to apply the search to. For instance instead of IQueryable of Users I may have an IQueryable of Cars and instead of firstname and surname the search goes off Make and Model. Basically the goal is to reuse the search logic by dynamically selecting what to search on at runtime.

• Clipboard Debugging

  - by Jake Pearson

  In the olden times of .NET 1.1, I could use the SoapFormatter to find out exactly what was getting serialized when I copied an object into the clipboard. Fast forward to 2010, and I tried to do the same trick. It turns out the SoapFormatter does not support generics. Is there an alternative way to find out exactly what binary objects are serialized into the clipboard? For example lets say I have this class: public class Foo { public List<Goo> Children; } If I send an instance of it to the clipboard, I would like to take a look at what is in the clipboard to see if it's children list was included or not. Update: I was finally able to find the over copied field with the debugger. Visual Studio did it's job.

• Writing from an array to a file bash and new lines

  - by S1syphus

  I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

• How do I fix this NameError?

  - by Kyle Kaitan

  I want to use the value v inside of an instance method on the metaclass of a particular object: v = ParserMap[kind][:validation] # We want to use this value later. s = ParserMap[kind][:specs] const_set(name, lambda { p = Parser.new(&s) # This line starts a new scope... class << p define_method :validate do |opts| v.call(self, opts) # => NameError! The `class` keyword above # has started a new scope and we lost # old `v`. end end p }) Unfortunately, the class keyword starts a new scope, so I lose the old scope and I get a NameError. How do I fix this?

• In Ruby, can the coerce() method know what operator it is that requires the help to coerce?

  - by Jian Lin

  In Ruby, it seems that a lot of coerce() help can be done by def coerce(something) [self, something] end that's is, when 3 + rational is needed, Fixnum 3 doesn't know how to handle adding a Rational, so it asks Rational#coerce for help by calling rational.coerce(3), and this coerce instance method will tell the caller: # I know how to handle rational + something, so I will return you the following: [self, something] # so that now you can invoke + on me, and I will deal with Fixnum to get an answer So what if most operators can use this method, but not when it is (a - b) != (b - a) situation? Can coerce() know which operator it is, and just handle those special cases, while just using the simple [self, something] to handle all the other cases where (a op b) == (b op a) ? (op is the operator).

• Grails application hogging too much memory

  - by RN

  Tomcat 5.5.x and 6.0.x Grails 1.6.x Java 1.6.x OS CentOS 5.x (64bit) VPS Server with memory as 384M export JAVA_OPTS='-Xms128M -Xmx512M -XX:MaxPermSize=1024m' I have created a blank Grails application i.e simply by giving the command grails create-app and then WARed it I am running Tomcat on a VPS Server When I simply start the Tomcat server, with no apps deployed, the free memory is about 236M and used memory is about 156M When I deploy my "blank" application, the memory consumption spikes to 360M and finally the Tomcat instance is killed as soon as it takes up all free memory As you have seen, my app is as light as it can be. Not sure why the memory consumption is as high it is. I am actually troubleshooting a real application, but have narrowed down to this scenario which is easier to share and explain.

• Deploy CakePHP to a subfolder

  - by mgroves

  I have created a CakePHP 2 app, and now I'm trying to deploy it to a production web server. My app uses the default folder structure (app/lib/plugins/vendors), default htaccess, default routing, nothing special. I've been developing locally as if the app were in the root folder of the site (e.g. http://mycakeapp.localhost/ takes me to the site). But I'm deploying to a site (shared hosting) where that will not be the case (e.g. http://www.somedomain.com/mycakeapp). It doesn't work (I didn't really expect it to), so I assumed I had to tweak one or more htaccess files. I tried modifying the root .htaccess as suggested in this post, but that only partially worked (the link to the CSS didn't work, for instance): <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^mycakeapp$ mycakeapp/app/webroot/ [L] RewriteRule ^mycakeapp/(.*)$ mycakeapp/app/webroot/$1 [L] </IfModule> So what should I do to all the htaccess files to make this CakePHP site work in a subfolder?

• How should I move my code from dev to production?

  - by Teddy

  I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

• How to handle subclasses in JasperReports?

  - by gotch4

  I've two classes (A and B) that extend a base class BASE. I need to make a report that takes an array of such classes and the prints the fields of A or B. I tought of using conditional expressions, then casting to one or another (depending on a field value). But I can't cast, because I don't know how to refere to the current bean. To do this I am using a JRBeanCollectionDataSource filled with a List<BASE>. How do I cast every bean to A or B in a report (or subreport)? I tried: ((A)this) but it says basically that this contains the report instance, not the current bean and gives error.

• Unit Testing Model Classes that inherit from NSManagedObject

  - by Matt Baker

  So...I'm trying to get unit tests set up in my iPhone App but I'm having some issues. I'm trying to test my model classes but they inherit directly from NSManagedObject. I'm sure this is a problem but I don't know how to get around it. Everything is building and running as expected but I get this error when calling any method on the class I'm testing: Unknown.m:0:0 unrecognized selector sent to instance 0xc2b120 If I follow this structure (http://chanson.livejournal.com/115621.html) to create my object in my tests I end up with another error entirely but it still doesn't help me.

• Do you have any tips for comments to keep them in step with the code? [closed]

  - by Rob Wells

  Possible Duplicate: How do you like your comments? G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise. Thanks to my, seemingly, SO shadow for pointing it out - wouldn't have thought I was that interesting. Now off to read the original post and see if it is relevant. Edit: I meant to emphasise the best appraoch to ensure that your comments will stay in step with the code. Maybe expressing an intent rather than the mechansim for instance.

Am I missing something or is there a different way of obtaining the same result? Thanks for helping

• Binding command to button in silverlight 4 using mvvm

  - by Archie

  Hello, I have a user control called HomePage.xaml. I'm creating a model instance (using MVVM pattern) in the code behind file in the constructor of page as MainViewModel model = new MainViewModel(); I have a button in HomePage.xaml which I want to bind to the command inside MainViewModel called GetData() and want to populate the data in datagrid. MainViewModel has an ObservableCollection which I would use to bind the data in datagrid. Populating the data in datagrid without binding command works fine. I'm binding the button as: <StackPanel x:Name="stkPanelInput" Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center"> <Button x:Name="buttonGetData" Width="70" Content="GetData" Command="{Binding GetData}" Click="buttonGetData_Click"/> </StackPanel> How shall I bind the command using MVVM? Thanks.

• Is it a good idea to "migrate business logic code into our domain model"?

  - by Bytecode Ninja

  I am reading Hibernate in Action and the author suggests to move business logic into our domain models (p. 306). For instance, in the example presented by the book, we have three entities named Item, Bid, and User and the author suggests to add a placeBid(User bidder, BigDecimal amount) method to the Item class. Considering that usually we have a distinct layer for business logic (e.g. Manager or Service classes in Spring) that among other things control transactions, etc. is this really a good advice? Isn't it better not to add business logic methods to our entities? Thanks in advance.

• NSThread running a class

  - by Thomas Joulin

  Hi, Every the example I find on the internet (including Apple doc) sets the target to self like this : [NSThread detachNewThreadSelector:@selector(threadedTask) toTarget:self withObject:nil]; Since i would like to do a more complex task in background (involving multiple methods), I thought of creating a class Task called like this : Task *task = [[Task alloc] init]; [NSThread detachNewThreadSelector:@selector(main) toTarget:task withObject:nil]; but I wonder, how will be handled the instance variables of my class Task ? in my method main can I safely call methods of my class Task using [self myMethod] and modifying members variables assuming I'm the only thread accessing it ? This way of handling threads seems weird to me, sorry if my question is stupid ^^ Thanks in advance

The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.
