• When debugging on WinCE, how can I set Visual Studio to always load symbol files it knows about?

  - by tsellon

  I'm debugging a WinCE, C++ program in Visual Studio across an ActiveSync connection. Every time I start the process it fails to load symbol information. However, if I right click on the module and hit 'Load Symbols' it correctly locates the symbol information without any further prompting from me. Is there a way that I can set Visual Studio to either: (a) automatically load this symbol information, or (b) automatically break the process into the debugger once it's loaded (similar to what windbg does)? I'm guessing there's a setting somewhere, but I've yet to find it. Update: I forgot to mention in the original question that I'm not debugging with the instance of Visual Studio that created the exe.

• MongoMapper - undefined method `keys'

• django admin how to limit selectbox values

  - by SledgehammerPL

  model: class Store(models.Model): name = models.CharField(max_length = 20) class Admin: pass def __unicode__(self): return self.name class Stock(Store): products = models.ManyToManyField(Product) class Admin: pass def __unicode__(self): return self.name class Product(models.Model): name = models.CharField(max_length = 128, unique = True) parent = models.ForeignKey('self', null = True, blank = True, related_name='children') (...) def __unicode__(self): return self.name mptt.register(Product, order_insertion_by = ['name']) admin.py: from bar.drinkstore.models import Store, Stock from django.contrib import admin admin.site.register(Store) admin.site.register(Stock) Now when I look at admin site I can select any product from the list. But I'd like to have a limited choice - only leaves. In mptt class there's function: is_leaf_node() -- returns True if the model instance is a leaf node (it has no children), False otherwise. But I have no idea how to connect it I'm trying to make a subclass: in admin.py: from bar.drinkstore.models import Store, Stock from django.contrib import admin admin.site.register(Store) class StockAdmin(admin.ModelAdmin): def queryset(self, request): qs = super(StockAdmin, self).queryset(request).filter(ihavenoideawhatfilter) admin.site.register(Stock, StockAdmin) but I'm not sure if it's right way, and what filter set.

• why wont this tester complie

  student name and id and testgrade need to compile with tester but the student class has some problem i dont know what it is and the error message is Error: Syntax error on token "(", . expected this needs to complie with the tester class to be able to run public class Student { public static void main(String[] args) { // instant varible for name, id , and test grade private String name; private int id; private int testgrade; /** * construct class * @parm String newName * @parm String newId */ public Student(String newName, int newId); { name = newName; id = newId; } /** * getName method that return instant varible name */ public String getName() { return name; } /** * getId method that return instant varible id */ public int getId() { return id; } /** * setGrade method that sets the test grade variable * * @param int grade */ public void setGrade(int grade) { testGrade = grade; } /** * getGrade method that sets test grade instance variable * * @param int grade */ public int getGrade() { return testGrade; } } }

• IPhone UIView:Is it possible to enable userinteraction only on subviews?

  - by Syg

  Hi guys, I created a viewcontroller that displays a button which is used to slide a view onto the screen. The idea is to place for instance three such viewcontrollers onscreen, resulting in three buttons at the bottom of the screen providing navigation. The viewcontrollers get stacked, so to the top one is now overlaying the other views and therefore the other buttons. Only the top viewcontroller's button is working in this situation, where I would like all three of them to be clickable. I tried disabling userinteraction on the view and enabling it on the buttons only, but it looks like the superview settings overrule the subview settings. Any ideas?

• Am I immoral for using a variable name that differs from its type only by case?

  - by Jason Baker

  For instance, take this piece of code: var person = new Person(); or for you Pythonistas: person = Person() I'm told constantly how bad this is, but have yet to see an example of the immorality of these two lines of code. To me, person is a Person and trying to give it another name is a waste of time. I suppose in the days before syntax highlighting, this would have been a big deal. But these days, it's pretty easy to tell a type name apart from a variable name. Heck, it's even easy to see the difference here on SO. Or is there something I'm missing? If so, it would be helpful if you could provide an example of code that causes problems.

• Five development tools I can't live without

  - by bconlon

  When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

• Getting an empty response when calling CouchDB over ajax

  - by swilliams

  I'm new to CouchDB, so please bear with me. I have an instance of CouchDB running on a VM. I can access it just fine through the browser via futon or directly at: http://192.168.62.128:5984/articles/hot_dog Calling that URL in a browser returns the proper JSON. But, when I try to call that exact same URL via ajax, I get nothing: var ajaxUrl = 'http://192.168.62.128:5984/articles/hot_dog'; $.getJSON(ajaxUrl, null, function(data) { alert(data); }); Looking at the response header with Firebug shows me that the HTTP response was 200 and the content-length is the right size. Even the Etag matches with what is in CouchDB. But the response itself is empty! The URL is absolutely right; I've triple checked, and copy/pasted it directly (and besides it wouldn't give a 200 response if it weren't). I'm using jQuery 1.4.2, and CouchDB 0.8 What's going on?

• No method found compiler warning

  - by Magic Bullet Dave

  I have create a class from a string, check it is valid and then check if it responds to a particular method. If it does then I call the method. It all works fine, except I get an annoying compiler warning: "warning: no '-setCurrentID:' method found". Am I doing something wrong here? Is there anyway to tell the compiler all is ok and stop it reporting a warning? The here is the code: // Create an instance of the class id viewController = [[NSClassFromString(class) alloc] init]; // Check the class supports the methods to set the row and section if ([viewController respondsToSelector:@selector(setCurrentID:)]) { [viewController setCurrentID:itemID]; } // Push the view controller onto the tab bar stack [self.navigationController pushViewController:viewController animated:YES]; [viewController release]; Cheers Dave

• Unable to connect to a local MYSQL server on wireles LAN.

  - by Arnab

  Ok, Here is the technical description. My laptop's config: Ip Adress:192.168.2.5 Mysqlserver 5.0 on port : 3306 Operating system: Ubuntu jaunty (9.04) 3306 is open for both incoming and outgoing. My friend's laptop config: Ip Adress:192.168.2.4 Mysqlserver 5.0 on port : 3306 Operating system: Windows XP pro 3306 is open for both incoming and outgoing. Both are on a wireless LAN connected through a belkin router (192.168.2.1) Both the MYSQL servers have been given the sufficient GRANT privileges. I am also able to connect from 192.168.2.4 to 192.168.2.5's MYSQL instance but the vice versa is not happening. I am getting an (100061) error. Tried Telnetting on 3306; again happening from 192.168.2.4 to 192.168.2.5 but not the vice versa. Am I doing something wrong? Kindly suggest.

• Using ASP.NET Redirect without string URL?

  - by David Dietrich

  For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

• Highlighting in Solr 1.4 - requireFieldMatch

  - by Mark Redding

  I have an object Title : foo Summary : foo bar Body : this is a published story about a foo and a bar All three are set up as fields with stored=true. The user searches across my system for the word "foo" I would like to highlight foo in all three places. The user searches for the word foo in the title "title:foo" I only want to highlight foo within the title. When I added hl.requireFieldMatch=true and hl.usePhraseHighlighter=true as part of my query over to SOLR I am unable to get the highlighting in all three places when doing a generic non fielded search. Is there a way to get both scenarios to work? I had these two items turned off, but I am adding in some fielded portions of the query that the user does not see which only display Published items for instance. the problem is (foo AND status:published) is causing the word published in the body to highlight when the user only searched for the word "foo".

• NSNumber >= 13 won't retain. Everything else will.

  The code I'm currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS. I turned on NSZombieEnabled and am now getting *** -[CFNumber retain]: message sent to deallocated instance 0x3c78420.

• Deploying spring message driven pojo on weblogic 8.1

  Hello, I am trying to deploy a spring message message driven POJO on weblogic 8.1. It is a simple POJO, and it works fine being run outside of an application server, but the messages do not seem to be picked up at all. I have created empty home and remote interfaces, as well as a container bean class that contains an instance of the pojo which it gets from the application context. I then added this container bean class to the ejb-jar.xml as a . I have not been able to get the messages pick up. Does anyone have any suggestions as to what I am doing wrong? Could anyone point me to a tutorial on how to deploy a MDP? Thanks.

• Ignore duplicates in regex pattern

  - by gAMBOOKa

  I have a regex pattern that searches for words in a text file. How do I ignore duplicates? For instance, take a look at this code $pattern = '/(lorem|ipsum|daboom|pahwal|ababaga)/i'; $num_found = preg_match_all( $pattern, $string, $matches ); echo "$num_found match(es) found!"; echo "Matched words: " . implode( ',', $matches[0] ); If I have more than one say lorem in the article, the output will be something like this 5 matches found! Matched words: daboom,lorem,lorem,lorem,lorem I want the pattern to only find the first occurrence, and ignore the rest, so the output should be: 2 matches found! Matched words: daboom,lorem

• How do I correctly model data in SQL-based databases that have some columns in common, but also have

  For instance, let's say I have a User model. Users have things like logins, passwords, e-mail addresses, avatars, etc. But there are two types of Users that will be using this site, let's say Parents and Businesses. I need to store some different information for the Parents (e.g. childrens' names, domestic partner, salaries, etc.) than for the Businesses (e.g. industry, number of employees, etc.), but also some of it is the same, like logins and passwords. How do I correctly structure this in a SQL-based database? Thanks!

• How to find the mime type of a file in python?

  - by Daren Thomas

  Let's say you want to save a bunch of files somewhere, for instance in BLOBs. Let's say you want to dish these files out via a web page and have the client automatically open the correct application/viewer. Assumption: The browser figures out which application/viewer to use by the mime-type (content-type?) header in the HTTP response. Based on that assumption, in addition to the bytes of the file, you also want to save the MIME type. How would you find the MIME type of a file? I'm currently on a Mac, but this should also work on Windows. Does the browser add this information when posting the file to the web page? Is there a neat python library for finding this information? A WebService or (even better) a downloadable database? Edit: Thank you, Dave Webb.

• How is ImmutableObjectAttribute used?

  - by Thomas Levesque

  I was looking for a built-in attribute to specify that a type is immutable, and I found only System.ComponentModel.ImmutableObjectAttribute. Using Reflector, I checked where it was used, and it seems that the only public class that uses it is System.Drawing.Image... WTF? It could have been used on string, int or any of the primitive types, but Image is definitely not immutable, there are plenty of ways to alter its internal state (using a Graphics or the Bitmap.SetPixel method for instance). So the only class in the BCL that is explicitly declared as immutable, is mutable! Or am I missing something?

• IoC, Containers, and NServiceBus confusion

  - by andy

  Hey guys, here's my setup Castle Windsor is my container NServiceBus is itself using it's own container internally, Spring by default I'm implementing the PubSub config. Ok, if I have my Bus.Publish happening within my IWantToRunAtStartup class, then everything is fine. As a test for example on Run() we can start a timer and it'll go into a Service style loop. However, what if I want to abstract NServiceBus from my app, and have my app go: new CustomPulisherClass().Notify(ISomeMessage msg); In this situation, how do I implement CustomPublisherClass. My confusion is coming from the fact that NServiceBus is already running as a Service, it's already been "Started". How to I get at the correct instance of the Bus object? cheers andy

• Returning an anonymous class that uses a final primitive. How does it work?

  Hi, I was wondering if someone could explain how the following code works: public interface Result { public int getCount(); public List<Thing> getThings(); } class SomeClass { ... public Result getThingResult() { final List<Thing> things = .. populated from something. final int count = 5; return new Result { @Override public int getCount() { return count; } @Override public List<Thing> getThings(); return things; } } } ... } Where do the primitive int , List reference and List instance get stored in memory? It can't be on the stack.. so where? Is there a difference between how references and primitives are handled in this situation? Thanks a bunch, Tim P.

• Grabbing random object from ArrayList is not random.

  - by Isai

  I am creating a method where if you pass in a parameter of type Random, then it will return a random object. Here is basically what I am trying to do: public T choose(Random r) { int randomInt = r.nextInt(randomList.size()); // randomList is just a instance variable return randomList.get(randomInt); } The random list has this the following strings:[2, 2, 2, 1, 1, 1, 1, c, c, c, a, a, a, a] Then I made a driver with the following code for (int i = 0; i < 10; i++) { System.out.print(rndList.choose(rnd)); // rnd is initialized as a static Random variable } However my outputs are not coming out random. I used the debugger and found out that my choose method generates an integer that is relatively low, so it will always print out either 2's or 1's but never c's or a's. I can't figure out why this is happening and help would be greatly appreciated.
