• Why are developers proud to say our application is XXX lines of code? [closed]

  - by mbcrump

  I admit, I used to do it. I was proud to tell a fellow developer my application is 10K+ lines of code. I thought it was a "Look at me, I'm smart" statement. Time passed and I realized that a experienced developer would be constantly refactoring all of his code. Not only for the sake of remembering what it was doing, but because he realizes he is smarter today than he was yesterday. No longer was it cool to have multiple nested if statements or completely ignoring generics/lambdas. So, whats your take on this? Do you do it and why?

• ExceptionHandling with Spring 3

  - by mjf

  I have this controller: @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; The excel wiew opens actually a ExcelViewer, which is build in method protected void buildExcelDocument(Map<String, Object> map, WritableWorkbook ww, HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception { Class.writecontent Class.writeMoreContent Called methods write content to the Excel sheet and they can throw e.g biffException. How can I show a certain error page when Exception is occured? I tried this @Controller public class ExcelController { @ExceptionHandler(BiffException.class) public String handleException(BiffException ex) { return "fail"; } @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; } } But I'm getting the server's error message about Exceptions. Maybe a bean definition missing?

• LuaInterface: add a table to the script scope

  - by user93422

  Question: how can I insert a table from C# into 'LuaInterface' script scope using a C# object (preferably anonymous type)? /// I want to do this, but it does not work /// (complains that 'test' is userdata and not table /// when I pass it to pairs() in the script) //lua["test"] = new { A = 1, B = 2 }; /// another option /// but building this string is a PITA (actual string is nested and long). lua.DoString("test = { A = 1, B = 2 }"); // So I have to do this lua.NewTable("test"); ((LuaTable) lua["test"])["A"] = 1; ((LuaTable) lua["test"])["B"] = 2; lua.DoString("for k,v in pairs(test) do print(k..': '..v) end");

• WCF net.tcp server disconnects - how to handle properly on client side?

  - by RoastedBattleSquirrel

  I'm stuck with a bit of an annoying problem right now. I've got a Silverlight 4 application (which runs OOB by default). It uses WCF with net.tcp as means of communicating with the server. The client uses a central instance of the wcf client proxy. As long as everything keeps running on the server side, everything's fine. If i kill the server in the middle of everything, i drown in an avalanche of exceptions on the client side (connection lost, channel faulted etc etc). Now i'm looking for a way to handle this in a clean and centralized way (if centralized is possible). The SL app has one central client object sitting in App.cs (public static MyClient Client { get;set;}), which gets initialized on application start. Any idea how to properly handle any connectivity problems on the client object?

• Why is TargetInvocationException treated as uncaught by the IDE?

  - by Jason Coyne

  I have some code that is using reflection to pull property values from an object. In some cases the properties may throw exceptions, because they have null references etc. try { child.Target = propertyInfo.GetValue(target, null); } catch (TargetInvocationException ex) { child.Target = ex.InnerException.Message; } catch (Exception ex) { child.Target = ex.Message; } Ultimately the code works correctly, however when I am running under the debugger : When the property throws an exception, the IDE drops into the debugger as if the exception was uncaught. If I just hit run, the program flows through and the exception comes out as a TargetInvocationException with the real exception in the InnerException property. How can I stop this from happening?

• Getting meaningful error messages from fstream's in C++

  - by Hassan Syed

  What is the best way to get meaningful file access error messages, in a portable way from std::fstreams ? The primitiveness of badbits and failbits is getting to be bit annoying. I have written my own exception hierarchies against win32 and POSIX before, and that was far more flexible than the way the STL does it. I am getting "basic::ios_clear" as an error message from the what method of a downcasted catch (std::exception) of a fstream which has exceptions enabled. This doesn't mean much to me, although I do know what the problem is I'd like my program to be a tad more informative so that when I start deployment a few months later my life will be easier. Is there anything in Boost to extract meaningful messages out of the ofstream's implementation cross platform and cross STL implementation ?

• regex: trim all strings directly preceeded by digit except if string belongs to predefined set of st

  - by Geert-Jan

  I've got addresses I need to clean up for matching purposes. Part of the process is trimming unwanted suffices from housenumbers, e.g: mainstreet 4a --> mainstreet 4. However I don't want: 618 5th Ave SW --> 618 5 Ave SW in other words there are some strings (for now: st, nd, rd, th) which I don't want to strip. What would be the best method of doing this (regex or otherwise) ? a wokring regex without the exceptions would be: a = a.replaceAll("(^| )([0-9]+)[a-z]+($| )","$1$2$3"); //replace 1a --> 1 I thought about first searching and substiting the special cases with special characters while keeping the references in a map, then do the above regex, and then doing the reverse substitute using the reference map, but I'm looking for a simpler solution. Thanks

• Using WiX, how do I change a property of a subfolder of a virtual directory?

  - by Joergen Bech

  I have a hierarchy of Directory elements in a WiX script. I also have a component that creates a virtual directory (using IIS:WebVirtualDir), which points to the root of my Directory hierarchy. How do I change a property (e.g. AnonymousAccess) of a subfolder of the virtual directory, e.g. MyVirtualDir <<< this is the virtual directory root MyVirtualDir\MySubFolder <<< this is the subfolder for which I wish to change a property using WebDirProperties Please note that I do not wish to create a new virtual directory for the subfolder. I only wish to change a few security settings. The current script is too big to post here, but take a look at the WiX tutorial: 5.3 Web Directory. Suppose in that example that there was another Directory element named "MySubFolder" nested within the "InstallDir" element. What would then be the next step in order to set properties for "MySubFolder" without turning it into a virtual directory?

• Fault exception trashes a register causing a crash in [NSInvocation invoke]

  - by Mike Weller

  I have an NSOperation which fetches some objects from a core data persistent store and sums up a few totals. Sometimes an object is deleted while the operation in in progress, so a core data fault exception occurs. I try/catch the exception while summing to ignore it because I just want to skip objects that cannot be faulted in. However, when one of these fault exceptions occurs (and I swallow it) there is a crash after the invocation returns in [NSInvocation invoke]. It's a bad memory access when dereferencing the value in r10 which according to GDB on a successful run points to one of these: (gdb) x 0x38388348 0x38388348 <OBJC_IVAR_$_NSInvocation._retdata>: 0x00000008 If a fault exception occured a value of 0x02 is in the register which causes the crash. A quick google search tells me that r10 should be saved by the callee, meaning it is not being restored by whatever code is changing it when this exception occurs. Can anybody explain this? I'm not an expert when it comes to these kinds of low-level details

• Python - from file to data structure?

  - by Seafoid

  Hi, I have large file comprising ~100,000 lines. Each line corresponds to a cluster and each entry within each line is a reference i.d. for another file (protein structure in this case), e.g. 1hgn 1dju 3nmj 8kfn 9opu 7gfb 4bui I need to read in the file as a list of lists where each line is a sublist, thus preserving the integrity of the cluster, e.g. nested_list = [['1hgn', '1dju', '3nmj', '8kfn'], ['9opu', '7gfb'], ['4bui']] My current code creates a nested list but the entries within each list are a single string and not comma separated. Therefore, I cannot splice the list with indices so easily. Any help greatly appreciated. Thanks, S :-)

• Get client timezone (not GMT offset amount) in JS

  - by Rex M

  I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

• Why is this std::bind not converted to std::function?

  - by dauphic

  Why is the nested std::bind in the below code not implicitly converted to an std::function<void()> by any of the major compilers (VS2010/2012, gcc, clang)? Is this standard behavior, or a bug? #include <functional> void bar(int, std::function<void()>) { } void foo() { } int main() { std::function<void(int, std::function<void()>)> func; func = std::bind(bar, 5, std::bind(foo)); std::cin.get(); return 0; }

• android: ListView.setAdapter() is causing IllegalStateException. Not sure how to fix it.

  - by Stev0

  I'm trying to populate a listview with the contents of various ListAdapters based upon the results of a switch statement nested in an OnItemClickListener. When clicking the item, the application was force closing, so I ran it through the dev tools and android debugger. Eclipse is showing me the in the main thread that the application has suspended due an IllegalStateException. I have a marginal understanding of what the particular exception indicates, but not sure how to fix it, or what in my code is causing it to be thrown. Code as follows: final ListView lv = (ListView) findViewById(R.id.main_list); final String[] autos = getResources().getStringArray(R.array.auto_array); final ListAdapter la_auto = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_2, autos); And then further down in the portion dealing with the onclicklistener gallery.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { switch(gallery.getSelectedItemPosition()) { case 0: lv.setAdapter(la_auto); break;

• WCF returning custom types

  - by Gena Verdel

  Hi. I'm a newbie to WCF, trying to perform relatively simple task. I'm trying to return list of objects read from the database but cannot overcome some really annoying exceptions. The question is very simple? What's wrong with the picture? [ServiceContract] public interface IDBService { [OperationContract] string Ping(string name); [OperationContract] InitBDResult InitBD(); } public InitBDResult InitBD() { _dc = new CentralDC(); InitBDResult result = new InitBDResult(); result.ord = _dc.Orders.First(); return result; } [DataContract] public class InitBDResult { //[DataMember] //public List<Order> Orders { get; set; } [DataMember] public Order ord { get; set; } }

• Is GOTO really as evil as we are led to believe?

  - by RoboShop

  I'm a young programmer, so all my working life I've been told GOTO is evil, don't use it, if you do, your first born son will die. Recently, I've realized that GOTO actually still exists in .NET and I was wondering, is GOTO really as bad as they say, or is it just because everyone says you shouldn't use it, so that's why you don't. I know GOTO can be used badly, but are there any legit situations where you may possibly use it. The only thing I can think of is maybe to use GOTO to break out of a bunch of nested loops. I reckon that might be better then having to "break" out of each of them but because GOTO is supposedly always bad, I would never use it and it would probably never pass a peer review. What are your views? Is GOTO always bad? Can it sometimes be good? Has anyone here actually been gutsy enough to use GOTO for a real life system?

• Is this bad style of programming(C#) ?

  - by m0s

  Hi, so in my program I have parts where I use try catch blocks like this try { DirectoryInfo dirInfo = new DirectoryInfo(someString); //I don't know if that directory exists //I don't know if that string is valid path string... it could be anything //Some operations here } catch(Exception iDontCareWhyItFailed) { //Didn't work? great... we will say: somethings wrong, try again/next one } Of course I probably could do checks to see if the string is valid path (regex), then I would check if directory exists, then I could catch various exceptions to see why my routine failed and give more info... But in my program it's not really necessary. Now I just really need to know if this is acceptable, and what would a pro say/think about that. Thanks a lot for attention.

• What is the flag to show the nesting of views in a Mac app?

  - by theMikeSwan

  I have just spet the last few hours trying to find the flag to use in Terminal to launch an app with the colored outlines around the various view elements to show how they are nested. I know that Matt Gemmell covered it during the Cocoa Face Off session of NSConference 2009 (at about the 13minute mark in the video). Unfortunately I can't actually read what he types and he doesn't speak the exact command. I know it has to be in the Apple docs somewhere but the search system is currently not being of any use. It looks like her just adds -showAllViews YES to the end of the command to open TextEdit but that command has no effect in 10.6.6. I have also tried every other capitalization I can think of as well as using view instead of views. Every command opens TextEdit just fine but doesn't show the colored outlines.

• Should the spacing between parent and child containers belong to parent or child?

  - by johntrepreneur

  I'm struggling to determine where in my CSS the padding/margins should go to keep seperation between parent and child containers. For example, if you have have a parent div with two nested children and you need to have even 10px spacing between the children and also have the children be spaced 10 px from the parent; then would you add padding to parent div {padding:10px} and then just add 10px of margin between the children? Or would you leave the parent at 0 padding and have the children define what seperation they need from each other and also their parents?

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• MySQL with Java: Open connection only if possible

  - by emempe

  I'm running a database-heavy Java application on a cluster, using Connector/J 5.1.14. Therefore, I have up to 150 concurrent tasks accessing the same MySQL database. I get the following error: Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections This happens because the server can't handle so many connections. I can't change anything on the database server. So my question is: Can I check if a connection is possible BEFORE I actually connect to the database? Something like this (pseudo code): check database for open connection slots if (slot is free) { Connection cn = DriverManager.getConnection(url, username, password); } else { wait ... } Cheers

• Ideas for Quick Hierarchical Listing - .NET

  - by Robert

  I have a table in SQL Server listing corporate departments and their sections and subsections (3 levels). I would like to create some web-based listing of this, but similar to a TreeList. I was thinking to set up nested Ajax Accordions, but it was taking me way too long to put together. I would even settle for a GridView with non-repeating column values. Is there a way I can implement my idea without it taking me more than an hour or so for a newbie to complete? Any controls in ASP.NET or Ajax I can bind to would be great.

• How can I tell what files are currently open by a process (i.e. my app)?

  - by chaiguy

  I am using a Lucene.Net index and want to give the user an option to move the index, but am having trouble closing it down so the directory/contents can be moved (I keep getting access denied exceptions). I need to be able to have some more information so I can debug this problem, such as being able to tell what files are currently open, and as much information about each use as possible. Alternatively, is there any way to simply force close a bunch of files so they can be moved? This would make things a lot easier to solve.

• Breakpoint pointing out "objc_autoreleaseNoPool"

  - by Andrew

  So I'm debugging an app in preperation for its app so release, and I enabled a universal breakpoint for "All Exceptions". Since then, everytime I run the app, the console prints: Catchpoint 2 (throw)Pending breakpoint 1 - "objc_exception_throw" resolved objc[11765]: Object 0x8f18ff0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f190a0 of class __NSCFNumber autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f1fef0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug Literally printed 3 times. I have no idea what this means but it looks bad. Any advice would be appreciated.

• Navigation properties not set when using ADO.NET Mocking Context Generator

  - by olenak

  I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!

• Entity update from ASP.NET MVC page with post to Edit action

  - by mare

  I have a form that posts back to /Edit/ and my action in controller looks like this: // // POST: /Client/Edit [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Client client) My form includes a subset of Client entity properties and I also include a hidden field that holds an ID of the client. The client entity itself is provided via the GET Edit action. Now I want to do entity update but so far I've only been trying without first loading the entity from the DB. Because the client object that comes in POST Edit has everything it needs. I want to update just those properties on the entity in datastore. So far I've tried with Context.Refresh() and AttachTo() but with no success - I'm getting all sorts of exceptions. I inspected the entity object as it comes from the web form and it looks fine (it does have an ID and entered data) mapped just fine. If I do it with Context.SaveChanges() then it just inserts new row..
