• ListView and undeterminate ProgressBar

  - by Spredzy

  Sorry for the question it might sounds stupid, But: how do you activate a ProgressBar according to the cell you just cliked on ? I have a list view, with a menu that shows after a long press. When I click on one of my option I would like to display the ProgressBar in the listView according to the cell I clicked on. It is currently always displaying the one of my first cell, whatever I am doing public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); switch (item.getOrder()) { case 0: mProgressBar = (ProgressBar)findViewById(R.id.welcome_progressbar); mProgressBar.setVisibility(View.VISIBLE); ... some execution .... return true; case 1: ... Does anyone see anything wrong?

• Javascript debugging: stopping/breaking at every javascript invocation

  - by portoalet

  I am dealing with a complex legacy javascript code base, and it's difficult to figure out where to put breakpoint (I have to find the files, put a breakpoint in firebug etc). Is there a way so that Firebug breaks on the first javascript execution that it encounters every time? In other words, every time I click on something on the page, and if a javascript code is executed, I want Firebug to break on that line? Of course I don't want Firebug to stop when it executes it's internal javascript. Is this possible?

• Why is there a limit of max 20 parameters to a clojure function

  - by GuyC

  Hi, there seems to be a limit to the number of parameters a clojure function can take. When defining a function with more than 20 parameters I receive the following: Obviously this can be avoided, but I was hitting this limit porting the execution model of an existing DSL to clojure, and I have constructs in my DSL like the following, which by macro expansion can be mapped to functions quite easily except for this limit: (defAlias nn1 ((element ?e1) (element ?e2)) number "@doc features of the elements are calculated for entry into the first neural network, the result is the score computed by the latter" (nn1-recall (nn1-feature00 ?e1 ?e2) (nn1-feature01 ?e1 ?e2) ... (nn1-feature89 ?e1 ?e2))) which is a DSL statement to call a neural network with 90 input nodes. Can work around it of course, but was wondering where the limit comes from. Thanks.

• Macros no longer working in VS2005

  - by NPVN

  I'm using VS2005 on Vista. I'm using some macros, but now they have suddenly stopped working. No error messages of any kind. I am not aware of having done anything that could trigger this. I have made sure that "Allow macros to run" is checked in Tools-Options-Addin/Macro Security. I have tried running the macros from a keyboard shortcut, from the Macro Explorer, and from the Macros IDE, all in vain: The little spinning icon displays shortly (<1 sec) and then disappears without the macro being executed. I have tried putting a breakpoint on the first line of the macro and then executing it from the main IDE, with no effect (the breakpoint isn't hit). I have tried the same from the Macro IDE: The state changes to "running", but the breakpoint isn't hit. I have to break the execution manually. Any ideas?

• C builder RAD 2010 RTL/VCL Application->Terminate() Function NOT TERMINATING THE APPLICATION

  - by ergey

  Hello, I have problem descriebed also here: http://www.delphigroups.info/3/9/106748.html I have tryed almost all forms of placing Application-Terminate() func everywhere in the code, following and not 'return 0', 'ExitProcess(0)', 'ExitThread(0)', exit(0). None working variant closes the app. Instead the code after Application-Terminate() statement is running. I have two or more threads in the app. I tryed calling terminate func in created after execution threads and in main thread. Also this is not related (as i can imagine) with CodeGuard / madExcept (i have turned it off and on, no effect). CodeGuard turning also did not do success. What i should do to terminate all the threads in c builder 2010 application and then terminate the process? Thank you.

• Why does Sql Server recommends creating an index when it already exist?

  - by Pierre-Alain Vigeant

  I ran a very basic query against one of our table and I noticed that the execution plan query processor is recommending that we create an index on a column The query is SELECT SUM(DATALENGTH(Data)) FROM Item WHERE Namespace = 'http://some_url/some_namespace/' After running, I get the following message // The Query Processor estimates that implementing the following index could improve the query cost by 96.7211%. CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[Item] ([Namespace]) My problem is that I already have such index on that column: CREATE NONCLUSTERED INDEX [IX_ItemNamespace] ON [dbo].[Item] ( [Namespace] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] Why is Sql Server recommending me to create such index when it already exist?

  I have NUnit installed at this directory. C:\Program Files\NUnit 2.5.5\bin\net-2.0 When I try to run my unit test (mut.dll) in some random directory. I get the following error. I have to copy the mut.dll under the NUnit directory in order to run it.

• PHP set timeout for script, set_time_limit not working

  - by tehalive

  I have a command-line PHP script that runs a wget request using each member of an array with foreach. This wget request can sometimes take a long time so I want to be able to set a timeout for killing the script if it goes past 15 seconds for example. I have PHP safemode disabled and tried set_time_limit(15) early in the script, however it continues indefinitely. I've given up troubleshooting set_time_limit() and was trying to find other ways to kill the script after 15 seconds of execution. However, I'm not sure if it's possible to check the time a script has been running while it's in the middle of a wget request at the same time (a do while loop did not work). Thanks for any tips!

• Unable to catch exception from Activator.CreateInstance.

  - by Patrik Hägne

  OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

• Create iPhone app programmatically, in its entirety

  - by miorel

  I recently became interested in iPhone app development, so I've been looking at online tutorials, and also reading a book, trying out the examples as I go along. I'm getting better, but one of the things I still find quite annoying about the usual development model is that I really have no idea what the SDK is really doing behind the scenes to make the app "work" because Apple protects me from this. For example, when I make connections on interface builder, this presumably corresponds to code being generated somewhere... Where that code is and what it does and how it works are not obvious (to me). So I'm wondering, is it possible to create an iPhone app entirely programmatically? That is, have execution start in some main method, which will then programmatically create any views, register event listeners, etc. And if yes, what are some good resources for something like this?

• How to list the code of a verb in J

  - by MPelletier

  In the console, typing a single verb without parameters will print its content: tolower 3 : 0 x=. I. 26 > n=. ((65+i.26){a.) i. t=. ,y ($y) $ ((x{n) { (97+i.26){a.) x}t ) That's nice for development, but unexploitable during execution. Is there a way to do that dynamically? Is there a verb that can return the contents of another verb? For example: showverb 'tolower' or showverb tolower

• How to modify/replace option set file when building from command line?

  - by Heinrich Ulbricht

  I build packages from a batch file using commands like: msbuild ..\lib\Package.dproj /target:Build /p:config=%1 The packages' settings are dependent on an option set: <Import Project="..\optionsets\COND_Defined.optset" Condition="'$(Base)'!='' And Exists('..\optionsets\COND_Defined.optset')"/> This option set defines a conditional symbol many of my packages depend on. The file looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <DCC_Define>CONDITION;$(DCC_Define)</DCC_Define> </PropertyGroup> <ProjectExtensions> <Borland.Personality>Delphi.Personality.12</Borland.Personality> <Borland.ProjectType>OptionSet</Borland.ProjectType> <BorlandProject> <Delphi.Personality/> </BorlandProject> <ProjectFileVersion>12</ProjectFileVersion> </ProjectExtensions> </Project> Now I need two builds: one with the condition defined and one without. My attack vector would be the option set file. I have some ideas on what to do: write a program which modifies the option set file, run this before batch build fiddle with the project files and modify the option set path to contain an environment variable, then have different option sets in different locations But before starting to reinvent the wheel I'd like to ask how you would tackle this task? Maybe there are already means meant to support such a case (like certain command line switches, things I could configure in Delphi or batch file magic).

• sOperator as and generic classes

  - by abatishchev

  I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

• What are practical guidelines for evaluating a language's "Turing Completeness"?

  - by AShelly

  I've read "what-is-turing-complete" and the wikipedia page, but I'm less interested in a formal proof than in the practical implications of being Turing Complete. What I'm actually trying to decide is if the toy language I've just designed could be used as a general-purpose language. I know I can prove it is if I can write a Turing machine with it. But I don't want to go through that exercise until I'm fairly certain of success. Is there a minimum set of features without which Turing Completeness is impossible? Is there a set of features which virtually guarantees completeness? (My guess is that conditional branching and a readable/writeable memory store will get me most of the way there) EDIT: I think I've gone off on a tangent by saying "Turing Complete". I'm trying to guess with reasonable confidence that a newly invented language with a certain feature set (or alternately, a VM with a certain instruction set) would be able to compute anything worth computing. I know proving you can building a Turing machine with it is one way, but not the only way. What I was hoping for was a set of guidelines like: "if it can do X,Y,and Z, it can probably do anything".

• XQuery - problem with recursive function

  - by H4mm3rHead

  Hi all, Im new on this project and am going to write, what i thought was a simple thing. A recursive function that writes nested xml elements in x levels (denoted by a variable). So far I have come up with this, but keeps getting a compile error. Please note that i have to generate new xml , not query existing xml: xquery version "1.0"; declare function local:PrintTest($amount) { <test> { let $counter := 0 if ($counter <= $amount ) then local:PrintTest($counter) else return $counter := $counter +1 } </test> }; local:PrintPerson(3) My error is: File Untitled1.xquery: XQuery transformation failed XQuery Execution Error! Unexpected token - " ($counter <= $amount ) t" I never understood xquery, and cant quite see why this is not working (is it just me or are there amazingly few resources on the Internet concerning XQuery?)

• Eclipse Java Profiler

  - by Jeff Storey

  I know this has been asked before, but I have not found anything recent that really gives a good answer. I'm trying to find a free profiler for eclipse that works well. I would like a graphical breakdown of execution time in particular. I've tried TPTP but have had no luck at all with GUI apps (it took almost a minute for a GUI app to start and was virtually unusable on screen - it uses a lot of Java OpenGL, so I'm not sure if it has to do with that). I liked YourKit, but unfortunately it's not free. I even tried switching to NetBeans since they have a built in profiler. If anyone has had success with particular profilers (even if it was TPTP), I'd like to hear about it. Any recommendations would be greatly appreciated. thanks, Jeff

• Delete or comment out non-working JUnit tests?

  - by Chris Knight

  I'm currently building a CI build script for a legacy application. There are sporadic JUnit tests available and I will be integrating a JUnit execution of all tests into the CI build. However, I'm wondering what to do with the 100'ish failures I'm encountering in the non-maintained JUnit tests. Do I: 1) Comment them out as they appear to have reasonable, if unmaintained, business logic in them in the hopes that someone eventually uncomments them and fixes them 2) Delete them as its unlikely that anyone will fix them and the commented out code will only be ignored or be clutter for evermore 3) Track down those who have left this mess in my hands and whack them over the heads with the printouts of the code (which due to long-method smell will be sufficently suited to the task) while preaching the benefits of a well maintained and unit tested code base

• Can I use a *.tag from another *.tag file in the same /WEB-INF/tags folder?

  - by Ytsejammer

  Hello, I am trying to refactor my JSP code so that a small conditional test condition gets reused through a *.tag file. There are some big parts of my UI that depend on the value of a two-state property of an object present in the request. Let's say the property is 'gender' and the object is of type Person. Like I said, I would like to simplify & centralize the test on the gender property using a tag. For this purpose, I created two tag files: /WEB-INF/tags/if-male.tag /WEB-INF/tags/if-female.tag Now, I have another tiny spot that gets repeated in all over my application; let's say is the salutation to my site user. With this idea, I created a tag like this: /WEB-INF/tags/salutation.tag As you can imagine, I am trying to use the if-male/if-female test within the salutation.tag file to output 'Mrs.' or 'Mr.' like this: <%@ tag body-content="empty" %> <%@ taglib prefix="g" uri="/WEB-INF/tags" %> <g:if-male> Mr. </g:if-male> <g:if-female> Mrs. </g:if-female> Is the use of the if-male/if-female tags legal within the salutation.tag file? I have tried with such arrangement, but it looks like the JDeveloper 10.1.3.4 compiler gets confused and cannot deal with the salutation.tag tag invoking the other two tags in the same 'library' (folder under /WEB-INF/tags). The reference works perfectly in Jetty 6 and it looks like it works as well if I deploy the application to OC4J directly without relying on JDeveloper to pre-compile all my JSPs. I hope someone can shed some light on this. Thanks, YJ

• Trying to execute netdom.exe from a ruby script or IRB does nothing

  - by Joraff

  I'm trying to write a script that will rename a computer and join it to a domain, and was planning to call on netdom.exe to do the dirty work. However, trying to run this utility in the script (same results in irb) does absolutely nothing. No output, no execution. I tried with backticks and with the system() method. System() returns false for everything but system("netdom") (which returns true). Backticks never return anything but an empty string. I have verified that netdom runs and works in the environment the script will be running in, and I'm calling other command-line utilities earlier in the script that work (w32tm, getmac, ping). Here's the exact line that gets executed: `netdom renamecomputer %COMPUTERNAME% /NewName:#{newname} /force` FYI, This is windows 7 x64

• How to properly close a process with NppExec?

  - by Sam the Great

  I'm not sure what's going on here, but the following code continues running even after I end the process in the NppExec console with Ctrl-C (during the execution of the while loop). I restarted my computer to stop the Ctrl key sends. However, if I run the script in Window's cmd prompt, Ctrl-C ends the script just fine. import time import win32com.client shell = win32com.client.Dispatch("WScript.Shell") time.sleep(2) while True: shell.SendKeys('^') # Ctrl key time.sleep(0.5) The NppExec run command I used was: cmd /C python -u "$(FULL_CURRENT_PATH)" Let me know if there is any more information I can provide. Thanks.

• Can't set background colour for UIView from ViewController

  - by Curyous

  I have the following code in the view controller: - (void)viewDidLoad { [super viewDidLoad]; ThemeManager *themer = [ThemeManager sharedInstance]; UIView *theView = self.view; UIColor *forBackground = [themer backgroundColour]; [theView setBackgroundColor:forBackground]; } but when execution gets to the setBackgroundColor line, I get the following error: *** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40' There's got to be something simple that I'm doing wrong, how do I set the background colour? Do I have to subclass the view and do it in there? I'd prefer not to have the extra class, even though that is better separation of the whole model/view/controller thing. Update: value returned by [themer backgroundColour] is constructed using colorWithPatternImage:, could this make a difference?

• Efficient banner rotation with PHP

  - by reggie

  I rotate a banner on my site by selecting it randomly from an array of banners. Sample code as demonstration: <?php $banners = array( '<iframe>...</iframe>', '<a href="#"><img src="#.jpg" alt="" /></a>', //and so on ); echo $banners(rand(0, count($banners))); ?> The array of banners has become quite big. I am concerned with the amount of memory that this array adds to the execution of my page. But I can't figure out a better way of showing a random banner without loading all the banners into memory...

• ASP.net drop down dynamically styling and then remembering the styles on aborted submit

  - by peacedog

  So, I've got an ASP drop down list (this is .net 2.0). I'm binding it with data. Basically, when the page loads and it's not a post back we'll fetch record data, bind all the drop downs, and set them to their appropriate values (strictly speaking we: initialize page with basic set of data from DB, bind drop downs from DB, fetch actual record data from DB, set drown downs to appropriate settings at this time). What I want to do is selectively style the list options. So the database returns 3 items: ID, Text, and a flag indicating whether I the record is "active" (and I'll style appropriately). It's easy enough to do and I've done it. My problem is what happens when a form submission is halted. We have slightly extended the Page class and created an AddError() method, which will create a list of errors from failed business rule checks and then display them in a ValidationSummary. It works something like this, in the submit button's click event: CheckBizRules(); if(Page.IsValid) { SaveData(); } If any business rule check fails, the Page will not be valid. The problem is, when the page re-renders (viewsate is enabled, but no data is rebound) my beautiful conditional styling is now sadly gone, off to live in the land of the missing socks. I need to preserve it. I was hoping to avoid another DB call here (e.g. getting the list data back from the DB again if the page isn't valid, just for purposes of re-styling the list). But it's not the end of the world if that's my course of action. I was hoping someone might have an alternative suggestion. I couldn't think of how to phrase this question better, if anyone has any suggestions or needs clarification don't hesitate to get it, by force if need be. ;)
