• Apache HTTPClient returns an empty page

  - by mariosangiorgio

  Hi, I am using the Apache HTTPClient for Java and I'm facing a really strange issue. Sometimes when I try to get a dynamically generated page it returns its actual content, but other times (with another parameter) all I get is a short sequence of \t,\r and \n. How could I track what's going on on the different cases in order to find where is the bug? My usage of the library is pretty straightforward, all I do is this few calls on an initialized HTTPClient object: String content = "/pageIwant.jsp?parameter=10101010"; HttpGet request = new HttpGet(content); HttpResponse response = client.execute(targetHost, request); HttpEntity entity = response.getEntity(); String page = EntityUtils.toString(entity);

• How to run a recorded (HTML) selenium test from .NET

  - by Gaspar Nagy

  I run Selenium tests with Selenium RC from .NET (c#). In some cases, I would like to keep the test case source as HTML (to be able to modify it from Selenium IDE), but I would like to run/include these tests from my c# unit tests. Maybe it is obvious, but I can't find the API method in the Selenium Core to achieve this. Any idea how to do that? (I think the "includePartial" command in Selenium on Rails does the thing that I would need, but for c#.)

• How do you optimize database performance when providing results for autocomplete/iterative search?

  - by Howiecamp

  Note: In this question I'm using the term "autocomplete" (or "iterative search") to refer to returning search-as-you-type results, e.g. like Google Search gives you. Also my question is not specific to web applications vs. fat client apps. How are SQL SELECT queries normally constructed to provide decent performance for this type of query, especially over arbitrarily large data sets? In the case where the search will only query based on the first n characters (easiest case) am I still issuing a new SELECT result FROM sometable WHERE entry LIKE... on each keypress. Even with various forms of caching this seems like it might result in poor performance. In cases where you want your search string to return results with prefix matches, substring matches, etc. it's an even more difficult problem. Looking at a case of searching a list of contacts, you might return results that match FirstName + LastName, LastName + FirstName, or any other substring.

• Jython: Is there any difference between adding to sys.path vs passing -D?

  - by trinth

  I have a python application that is trying to load some Java libraries (specifically Axis2 web services). When I add the necessary jars in Eclipse via PyDev Project Source Folders, everything seems to work fine. However, I want to be able to do this at run time by adding to sys.path, but then my application doesn't seem to work. In both cases I can load the jars just fine, but something must be different for there to be different results. My question is, is there a difference between adding jars via the sys.path at run time with sys.path.append() versus passing -D to the jython interpreter?

• How to enforce lazy loading of entities on certain conditions

  - by Samuel

  We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

• Eclipse Plugin: Enablement of an Action based on the current selection - before the

  - by Itay

  Here's my problem: I am using the org.eclipse.ui.popupMenus extension point for adding a sub-menu whose Action that is bounded to the following class: public class MyAction implements IObjectActionDelegate { private Logic logic = Logic.getInstance(); // Singleton public void setActivePart(IAction a, IWorkbenchPart targetPart) { // Nothing here } public void run(IAction a) { // Do something... } public void selectionChanged(IAction a, ISelection s) { a.setEnabled(logic.isEnabled(s)); } } This action is working correctly in most cases (including the call a.setEnabled() in selectionChanged()). My problem at the very first time my action is being invoked. The selectionChanged method is called only after the menu item has been displayed (and not when the user has made the selection) which means that the call to a.setEnabled() will have no affect. Any ideas on how to make my action receive selectionChanged() notifications even before the fist time it is being invoked?

• What do you enjoy about programming?

  - by Earlz

  Some of us here(or is it just me?) enjoy programming. Even if we're not being paid for it, and in some cases, even though the end result will not do anything for us. For example, many people do the Project Euler problems just for fun, and in the end nothing was really "accomplished" materially. What is it that makes us enjoy programming? How is programming different from another job? You don't see an accountant going home to do some accounting on their own time just for the pure joy of it. How are we different? (also, if anyone has some ideas on how to tag this, then please do correct it for me.. )

• asp:QueryStringParameter and empty query string parameter

  - by abatishchev

  I haveasp:GridView displaying client requests using asp:SqlDataSource. I want to limit displayed information by client: View.aspx has to display everything, View.aspx?client=1 has to display only requests from client ID #1. So I'm using <asp:QueryStringParameter Name="client" QueryStringField="client" /> for query "EXEC getRequests @client". Everything works properly when some client is specified. But don't - if not. I tested my SP using SSMS - it works properly in both cases - when parameter is specified and when it isn't (NULL passed explicitly). What have I do?

• C#: How to constuct a variable from another variables

  - by ozzwanted

  How to construct new variable in C#. I mean, to have sth like this public void updateXXX(string endingOfVariable, int newValue) { this.textBox_{endingOfVariable} = newValue; } This is implemented in Php: $a = 'var'; $b = 'iable'; $variable = 'var'; echo ${$a.$b}; But maybe it is possible in C#. The problem is that - I created ~500 textBoxes in C# Windows Form, and if I want to set a value, I need to build a switch() {case:; } statment with 500's cases.

• How do I get the resources of a working set?

  - by zvikico

  I know that Eclipse working sets are very flexible and customizable. They are made of elements which implement IAdaptable Which can be anything. However, in many (most) cases, working sets are used to define a set of resources. In case these elements can be seen as resources (e.g. IJavaProject), is there a universal (or formal) way to programatically translate these elements to resources? Eventually, I need to determine whether a given resource is in a working set, so an answer in that direction is acceptable as well.

• Database triggers / referential integrity and in-memory caching

  - by Ran Biron

  Do you see database triggers / referential integrity rules being used in a way that changes actual data in the database (changing row w in table x causes a change in row y in table z)? If yes, How does this tie-in with the increasing popularity of in-memory caching (memcache and friends)? After all, these actions occur inside the database but the caching system must be aware of them in order to reflect to correct state (or at least invalidate the possibly changed state). I find it hard to believe that callbacks are implemented for such cases. Does anyone have real-world experience with such a setup / real-world experience with considering such a setup and abandoning it (which way did you go? if caching, how do you enforce integrity?)

• How to switch iostream from binary to text mode and vice versa?

  - by Mad Fish

  I want to read both formatted text and binary data from the same iostream. How can I do that? Why? Imagine this situation: You have different resources, and resource loaders for them, that take a std::istream as a parameter. And there are a "resource source" that provides these streams. Resources can be both text and binary and I need to handle both cases with resource loaders. Or other situation: Image that you have an archive with resources of mixed types. How can I get a text stream from inside the binary archive stream?

• How would I initialize these two lists so that modifying one doesn't modify the other?

  - by Brandon

  I'm aware of why this is happening, but is there any way to do this without having to implement ICloneable or a Copy() method? Preferably .net 2.0, but 3.5 is fine if it is necessary. Essentially I'm trying to implement an undo method. In most cases I can just perform the reverse action in the Undo(), but for others that is not possible. So I want to keep two lists. One for the list of items that I will be modifying, and one for the original, unmodified list of items. This way if I need to do an undo, I just delete the modified items and replace them with the originals. Most of the ways I've tried to assign the _originalItems variable doesn't work, so what would I need to do? public MyClass(List<SelectedItems> selectedItems) { _selectedItems = new List<SelectedItems>(selectedItems); _originalItems = ?? }

• Proper thread termination in multi-threaded C# application

  - by Brian

  I have what I think is a rather complex problem. I have a C# application that utilizes a plug-in architecture using reflection. The application loads plug-in dlls and the user is able to enable/disable them. When a plug-in is enabled, the main app starts a thread to run the plug-in in. In many cases the plug-in may have multiple threads of its own. When I want to disable a plug-in I am calling Thread.Abort(). This seems to kill the initial thread that was created for the plug-in, but any additional threads that the plug-in created continue running. Is there a better way to stop all of the associated plug-in's threads along with the main thread? Thanks.

• Advantages of using WCF to work with Sharepoint Services WSS3.0?

  - by val

  Hi folks, what is your opinion or better off your practical experience using WCF to work with WSS instead of SP web services? I am writing some custom library for our software to store and retrieve files from WSS document libraries using sharepoint web services. I am not entirely happy with the performance of the sp web services - a bit too slow in many cases. Now, microsoft claims a significant improvements in WCF over remoting and I am looking into a good way to use WCF for my file services. Any suggestions or ideas? Maybe a good source of coding practices or blogs? Thanks a lot, Val

• Is a selector like *+* safe to use?

  - by mcmullins

  I recently came across this CSS selector while trying to find a way to easily space out major blog elements such as paragraphs and images. An example of its use would be something like this: .post *+* {margin-top: 15px;} /* or... */ .post > *+* {margin-top: 15px;} /* if you don't want the margin to apply to nested elements */ At first glance, it seemed pretty useful. So my question is: What downsides are there to using these selectors? Specifically: What's the browser support like for this? Are there any cases you wouldn't want an even margin spacing between elements in an article and if not, is it easier to declare this first and then overwrite or simply declare each element individually? Does this have performance issues since you're selecting everything twice?

• better for-loop syntax for detecting empty sequences?

  - by Dmitry Beransky

  Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

• What advantages can I get from learning C++ if I'm mainly a C# Programmer?

  - by Sergio Tapia

  Hello, Recently I've started to notice a lot of smirks and generally rude comments whenever I mention C#. Everyone I talk to either says learn Python or learn C++. Python is a nice language, I get it. But I don't find much use for it right now (for my use cases), and C++ I heard is a faster language (not sure). So my question is this, what advantage can I get from learning C++ (besides the knowledge and expansion of my horizons), when I mainly program in C#. If anyone can make a legitimate claim, I'll for sure look into learning the language because let's face it, I trust you guys. Thanks so much for all the help.

• Master data validation in service layer

  - by rakesh-nitj

  User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

• How to Audit Database Activity without Performance and Scalability Issues?

  - by GotoError

  I have a need to do auditing all database activity regardless of whether it came from application or someone issuing some sql via other means. So the auditing must be done at the database level. The database in question is Oracle. I looked at doing it via Triggers and also via something called Fine Grained Auditing that Oracle provides. In both cases, we turned on auditing on specific tables and specific columns. However, we found that Performance really sucks when we use either of these methods. Since auditing is an absolute must due to regulations placed around data privacy, I am wondering what is best way to do this without significant performance degradations. If someone has Oracle specific experience with this, it will be helpful but if not just general practices around database activity auditing will be okay as well.

• jQuery: What does (function($) {})(jQuery); mean?

  - by Legend

  I am just starting out with writing jQuery plugins. I wrote three small plugins but I have been simply copying the line into all my plugins without actually knowing what it means. Can someone tell me a little more about these? What does this do? (I know it extends jQuery somehow but is there anything else interesting to know about this) (function($) { })(jQuery); What is the difference between the following two ways of writing a plugin: Type 1: (function($) { $.fn.jPluginName = { }, $.fn.jPluginName.defaults = { } })(jQuery); Type 2: (function($) { $.jPluginName = { } })(jQuery); I could be way off here and maybe both mean the same thing. In some cases, this doesn't seem to be working in a plugin that I was writing using Type 1. Any idea why? But in either case, I would appreciate any explanation.

• .NET DefaultValue attribute

  - by Aaron

  I've heard people say a few different things about the DefaultValue attribute including: "It sets the value of the property before anything else uses it." "It doesn't work for autoproperties." "It's only for decoration. You must manually set actual default values." Which (if any) is right? Does DefaultValue actually set default values? Are there cases where it doesn't work? Is it best just not to use it?

• How I change a variable of a type to another one in C?

  - by drigoSkalWalker

  I want to do it: int main () { bla bla bla void *onetype; switch (USER_INPUT_TYPE) { CASE CONVERT_TO_CHAR: convert onetype VOID TO CHAR >>> HOW??? CASE CONVERT_TO_INT: convert onetype VOID TO INT >>> HOW??? LOT OF CASES... } } Yes, I know type casting, but type casting is a 'temporary' change. So, is there any way to accomplish it in C? EDIT : Stop stop stop! Please, see, what are you doing is type casting, I KNOW THIS, you are creating another variable of the desirable type like int i = (int) onetype, I don't want this, I want something else like onetype = (int) onetype, without recreate them, without allocate another variable. Thanks a lot guys!

• Qt/C++ event loop exception handling

  - by Georg

  I am having an application heavily based on QT and on a lot of third party libs. THese happen to throw some exceptions in several cases. In a native Qt App this causes the application to abort or terminate. Often the main data model is still intact as I am keeping it in pure Qt with no external data. So I am thinking that I could also just recover by telling the user that there has occured an error in this an that process and he should save now or even decide to continue working on the main model. Currently the program jsut silently exits without even telling a story. Please help.
