  • GEvent.addListener(...) return?

    - by user354436
    Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

  • Symfony2 & Twig - theming file upload widget

    - by Sacred Socks
    I have an Symfony2 edit form for an entity and one of the fields is for the user's profile picture. I'm trying to theme the Twig file upload widget so that the current picture set for the field is displayed above the file input. So far, I have: {% form_theme edit_form _self %} {% block field_widget %} {% set type = type|default('text') %} {% if type == 'file' %} <img src="{{ value }}" /> {% endif %} {{ block('form_widget_simple') }} {% endblock %} All works well except that the value variable is blank (which makes sense I guess). My question is how can I get hold of the path to the file? Is there a way to pick it out of the form values for the field? Could I perhaps pass it through as an option to the field? Srz if this is a dumb question, still pretty new to Symfony and Twig..

  • How do you run your unit tests? Compiler flags? Static libraries?

    - by Christopher Gateley
    I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

  • What are the semantics of [myThing.myProperty release]?

    - by dugla
    I clearly have not fully grocked properties. I have an instance of a class, myThing. myThing has a property that has be synthesized: // .h @property(nonatomic,retain)MyCoolType *coolType; // .m @synthesize coolType; In my program I call: // The retain count on MyCoolType is 1. [myThing.coolType release]; The reference count on MyCoolType is now zero and dealloc should fire. So, shouldn't myThing.coolType now be nil? In my code that is not the case. How do a correctly release and force the property to return nil? Thanks, Doug

  • Why does this VBS scheduled task (to call a URL) not work in Windows Server 2008?

    - by user303644
    This same script worked in older server OS environments, and even on my desktop; and allows me to kick off a nightly process on my website's URL. It simply will not execute the URL in my Windows Server 2008 environment. It does not generate any errors, claiming task completion I can pull the same URL up just fine in the server's web browser I have the script running with "highest privileges" I even tried to create a batch file which executes it, so I can explicitly "Run as Administrator" and it still will not execute the URL (but will not generate any errors either). I'm baffled as to why the task claims to have completed successfully, yet the script never reaches the URL. Call LogEntry() Sub LogEntry() 'Force the script to finish on an error. On Error Resume Next 'Declare variables Dim objRequest Dim URL Set objRequest = CreateObject("MSXML2.ServerXMLHTTP") 'Put together the URL link appending the Variables. URL = "http://myURL/AutorunNightlyTasks.aspx" 'Open the HTTP request and pass the URL to the objRequest object objRequest.open "GET", URL, False 'Send the HTML Request objRequest.send() 'Set the object to nothing Set objRequest = Nothing End Sub

  • Force Decimal Regex

    - by babyangel86
    Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

  • Up to date Ruby On Rails books?

    - by Earlz
    Hello, I've been trying to learn Rails for a while now and I just can not piece it all together with random blogs and SO questions, so I've decided I need a full book/ebook. Can anyone suggest a good one? I've been looking at Agile Web Development With Rails 4th edition. There is an old question about Ruby On Rails books but it is from 2008 and there has been new Rails releases since then. I basically would like a book that is more than a reference, but also doesn't assume I'm a non-programmer. Also, I already know a lot of Ruby. So, what books would you recommend that is up to date and also doesn't treat me like a baby?

  • Why should pop() take an argument?

    - by Stephano
    Quick background I'm a Java developer who's been playing around with C++ in my free/bored time. Preface In C++, you often see pop taking an argument by reference: void pop(Item& removed); I understand that it is nice to "fill in" the parameter with what you removed. That totally makes sense to me. This way, the person who asked to remove the top item can have a look at what was removed. However, if I were to do this in Java, I'd do something like this: Item pop() throws StackException; This way, after the pop we return either: NULL as a result, an Item, or an exception would be thrown. My C++ text book shows me the example above, but I see plenty of stack implimentations taking no arguments (stl stack for example). The Qustion How should one implement the pop function in C++? The Bonus Why?

  • Global search box extension - how to make browser to start when suggestion picked.

    - by Ramps
    Hi, I'm implementing global search box extension (sth like SearchableDictionary sample in android sdk). Everything works fine - suggestions are displayed properly. Problem is that I want browser to start when user picks a suggestion. (each suggestion is a link) Columns of my cursor contain SearchManager.SUGGEST_COLUMN_INTENT_DATA, and I use that to pass http link. My searchable xml contains default intent action set to: android:searchSuggestIntentAction="android.intent.action.VIEW". But when user hits the suggestion, my application is started instead of browser. What am I missing? Regards!

  • Doctrine SQL Server uniqueidentifier isn't cast as char or nvarchar when retrieved from the database

    - by Tres
    When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

  • BigInteger.ToString() returns more than 50 decimal digits.

    - by brickner
    I'm using .NET 4 System.Numerics.BigInteger Structure and I'm getting results different from the documentation. In the documentation of BigInteger.ToString() Method It says: The ToString() method supports 50 decimal digits of precision. That is, if the BigInteger value has more than 50 digits, only the 50 most significant digits are preserved in the output string; all other digits are replaced with zeros. I have some code that takes a 60 decimal digits BigInteger and converts it to a string. The 60 significant decimal digits string didn't lose any significant digits: const string vString = "123456789012345678901234567890123456789012345678901234567890"; Assert.AreEqual(60, vString.Length); BigInteger v = BigInteger.Parse(vString); Assert.AreEqual(60, v.ToString().Length); Assert.AreEqual('9', v.ToString()[58]); Assert.AreEqual('1', v.ToString()[0]); Assert.AreEqual(vString, v.ToString()); All the asserts pass. What exactly does the quoted part of the documentation mean?

  • Multi-threaded downloader in C# question

    - by blez
    Currently I have multi-threaded downloader class that uses HttpWebRequest/Response. All works fine, it's super fast, BUT.. the problem is that the data needs to be streamed while it's downloading to another app. That means that it must be streamed in the right order, the first chunk first, and then the next in the queue. Currently my downloader class is sync and Download() returns byte[]. In my async multi-threaded class I make for example, list with 4 empty elements (for slots) and I pass each index of the slot to each thread using the Download() function. That simulates synchronization, but that's not what I need. How should I do the queue thing, to make sure the data is streamed as soon as the first chunk start downloading.

  • Why my WCF Service returns xml serialized objects?

    - by user294554
    Hi, I'm new here and I hope anyonte can help me. I have WCF Service and Windows Forms working with this client written in VB.NET. The Service class started to return xml serialized objects, but all my classes on Service side are DataContract-s and the service class is DataContractFormat. I googled everywhere about serializations and I couldn't find reason why it started to do that. I checked my classes and service, app.config file, but I couldn't find anything. I checked Reference.vb class, and it's System.Xml.Serialization.XmlElementAttribute everywhere. The question may seem dummy, but I really don't know what to do. I just want to know what can cause the service to act like that. Thank you.

  • Help with output generated by this C code using fork()

    - by Seephor
    I am trying to figure out the output for a block of C code using fork() and I am having some problems understanding why it comes out the way it does. I understand that when using fork() it starts another instance of the program in parallel and that the child instance will return 0. Could someone explain step by step the output to the block of code below? Thank you. main() { int status, i; for (i=0; i<2; ++i){ printf("At the top of pass %d\n", i); if (fork() == 0){ printf("this is a child, i=%d\n", i); } else { wait(&status); printf("This is a parent, i=%d\n", i); } } }

  • Managing Data Prefetching and Dependencies with .NET Typed Datasets

    - by Derek Morrison
    I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with the same data, and I want the performance benefit of loading data in the beginning only once. My problem is that I don't know of a good way or pattern to use for managing dependencies (I want to be sure I load all the data that I'm going to need for each class/method that will use the dataset). Currently, I just end up looking through the code for the various classes that will use the dataset to make sure I'm loading everything appropriately. What are good approaches or patterns to use in this situation? Am I doing something fundamentally wrong? Although I'm using typed datasets, this seems like it would be a common situation where prefetching data is used. Thanks!

  • Need a push in the right direction, to write my first functional test in Rails

    - by Jason
    I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword true is simply returned, otherwise the keyword false is returned - its in only value returned & not contained in any <div>, <span> or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful!

  • How do I add a new ItemTemplate to a Guidance Automation Toolkit vs2010 .vsix package?

    - by Maslow
    I have a vs2008 GAT package that has been updated to work on vs2010 which walks a developer through creating a custom solution complete with a Service layer project, Domain, usercontrol, and unit test project. I'd like to add a new ItemTemplate to the package to create a user control or dialog that adheres to our current practices. So far it seems I need a Recipe, but I can not find any reference for the GuidancePackage.xml file and how to properly add things to it, let alone how to add a new Item Template or guidance steps and decisions. How can I add an item template to my add-in?

  • Multiple resultsets from Oracle in Odp.net,without refcursors

    - by James L
    SQL Server is able to return the results of multiple queries in a single round-trip, e.g: select a, b, c from y; select d, e, f from z; Oracle doesn't like this syntax. It is possible to use reference cursors, like this: begin open :1 for select count(*) from a; open :2 for select count(*) from b; end; However, you incur a penalty in opening/closing cursors and you can hold database locks for an extended period. What I'd like to do is retrieve the results for these two queries in one shot, using Odp.net. Is it possible?

  • Core Data produces Analyzer warnings

    - by RickiG
    Hi I am doing the final touch ups on an app and I am getting rid of every compiler/analyzer warning. I have a bunch of Class methods that wrap my apps access to Core Data entities. This is "provoking" the analyzer. + (CDProductEntity*) newProductEntity { return (CDProductEntity*)[NSEntityDescription insertNewObjectForEntityForName:@"CDProductEntity" inManagedObjectContext:[self context]]; } Which results in an Analyzer warning: Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected In the method that calls the above Class Method I have this: CDProductEntity *newEntity = [self newProductEntity]; Which results in an Analyzer warning: Method returns an Objective-C object with a +1 retain count (owning reference) Explicitly releasing or autoreleasing a Core Data entity is usually very very bad, but is that what it is asking me to do here? First it tells me it has a +0 retain count and that is bad, then it tells me it has a +1 which is also bad. What can I do to ensure that I am either dealing with a Analyzer hiccup or that I release correctly? Thanks in advance

  • Why does concatenating strings in the argument of EXEC sometimes cause a syntax error in T-SQL?

    - by Tim Goodman
    In MS SQL Server Management Studio 2005, running this code EXEC('SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR)) gives this error: Incorrect syntax near 'CAST' However, if I do this, it works: DECLARE @temp VARCHAR(4000) SET @temp = 'SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR) EXEC(@temp) I found an explanation here: http://stackoverflow.com/questions/1044831/t-sql-cannot-pass-concatenated-string-as-argument-to-stored-procedure According to the accepted answer, EXEC can take a local variable or a value as its argument, but not an expression. However, if that's the case, why does this work: DECLARE @temp VARCHAR(4000) SET @temp = CAST(3 AS VARCHAR) EXEC('SELECT * FROM employees WHERE employeeID = ' + @temp) 'SELECT * FROM employees WHERE employeeID = ' + @temp sure looks like an expression to me, but the code executes with no errors.

  • [Android] How do I load URL that requires login into variable?

    - by bebeTech
    I am trying to port my usage meter from a JavaScript Gadget (win) / Widget (OSX) to Android. Total newbie when comes to JAVA + Eclipse + Android 2.1 SDK. Essentially what I want to do is load a page, pass through a username and password and load the resulting page into a array that I can then run some regular expressions through. My code from JavaScript (I've replace the actual URL with a dummy one) is: xmlhttp.open("post","https://acme.com.au/your_account/index.php?function=login",false); xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.send("check_username=" + username + "&password=" + password); I need to know the Android equivalent to the above please. I've played around with WebView but that loads the page in a web browser which isn't what I want.

  • Remote stream multiple files in SOLR

    - by Mark
    I want to use SOLR's remote-streaming facility to extract and index the content of files. This works fine if I pass stream.file=xxx as a parameter to the http GET method. However, I have a lot of these, and want to batch them up (i.e. not have to have a GET per file). Is there a way I can do this in SOLR? e.g. I'd like to be able to POST some xml like this: <add> <doc stream_file="filename"> <field name="id">123</field> </doc> <doc>...

  • C# external tool for SSMS - Reading from stdin

    - by jheppinstall
    Hi all, I am trying to write an app that makes use of the external tools functionality of SQL Server Management Studio. To specify an external tool, you can enter a path to the app and specify some arguments to pass to the app via STDIN. Currently I just have a form that displays the arguments. Every time I run the external tool I get a new instance of the application. Ideally I would like for the first time I run the tool to load the application, and each subsequent running to take the arguments from STDIN and do something with them WITHOUT creating a new instance of the app. Is there anything I can do that could allow this, or am I stuck with lots of windows? Thanks in advance
