• Closing any open info windows in google maps api v3

  - by hhj

  As the title states, on a given event (for me this happens to be upon opening a new google.maps.InfoWindow I want to be able to close any other currently open info windows. Right now, I can open many at a time..but I want only 1 open at a time. I am creating the info windows dynamically (i.e. I don't know ahead of time how many will be generated), so in the click event of the current info window (which is where I want all the other open ones closed) I don't have a reference to any of the other open info windows on which to call close(). I am wondering how I can achieve this. I am not an experienced JavaScript programmer so I don't know if I need to use reflection or something similar here. Would the best way be just to save all the references in some sort of collection, then loop through the list closing them all? Thanks.

• Referencing View directory in asp.net mvc

  - by ooo

  i have some html files as part of a regular website that has been ported over to asp.net mvc. In my code i need to read and write these html files and stick them in a tinymce editor To be able to read and write this file from disk in the past i had a hard coded path but this doesn't seem to work in asp.net mvc unless i do something like this: Writing: string _urlDirectory = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; System.IO.File.WriteAllText(_urlDirectory, htmlData_); Reading: string url = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; var req = WebRequest.Create(url); var response = req.GetResponse(); StreamReader sr = new StreamReader(response.GetResponseStream()); string htmlData_ = sr.ReadToEnd(); i am moving my site from one data center to another and the directory structure is changing. instead of just changing the hard coded path to another hard coded path i wanted to see if there was a more relative way to reference these files.

• JQuery - is at least one checkbox checked

  - by Laramie

  I am in the process of learning JQuery thanks mostly to the positive reference here on Stack Overflow. I need a function that checks all the checkboxes in an element which have the same CSS class. It should returns true if at least one of them is checked. There are also other boxes in the element that are irrelevant to the check. The CSS class is unnecessary and only in place to create a way to identify the checkboxes in the group. It feels like bad practice, so any recommendations about other ways to identify them are welcome.

• R- delete rows in multiple columns by unique number

  - by Vincent Moriarty

  Given data like this C1<-c(3,-999.000,4,4,5) C2<-c(3,7,3,4,5) C3<-c(5,4,3,6,-999.000) DF<-data.frame(ID=c("A","B","C","D","E"),C1=C1,C2=C2,C3=C3) How do I go about removing the -999.000 data in all of the columns I know this works per column DF2<-DF[!(DF$C1==-999.000 | DF$C2==-999.000 | DF$C3==-999.000),] But I'd like to avoid referencing each column. I am thinking there is an easy way to reference all of the columns in a particular data frame aka: DF3<-DF[!(DF[,]==-999.000),] or DF3<-DF[!(DF[,(2:4)]==-999.000),] but obviously these do not work And out of curiosity, bonus points if you can me why I need that last comma before the ending square bracket as in: ==-999.000),]

• Static source code analysis with LLVM

  - by Phong

  I recently discover the LLVM (low level virtual machine) project, and from what I have heard It can be used to performed static analysis on a source code. I would like to know if it is possible to extract the different function call through function pointer (find the caller function and the callee function) in a program. I could find the kind of information in the website so it would be really helpful if you could tell me if such an library already exist in LLVM or can you point me to the good direction on how to build it myself (existing source code, reference, tutorial, example...). EDIT: With my analysis I actually want to extract caller/callee function call. In the case of a function pointer, I would like to return a set of possible callee. both caller and callee must be define in the source code (this does not include third party function in a library).

• How can i see if dealloc is being called on a uikit object, or any object not created by myself

  - by Gyozo Kudor

  I think i have an UIImage that has a higher retain count than it should have and i am probably leaking memory. I use this image as a thumbnail, to set a custom background to a uibutton. So the uibutton is holding a reference to it and so do i. But instead of 2, the retainCount is 3. Do i have to create a custom UIImage derived class and override dealloc if I want to place a log message there and then change the class used from UIImage to my class, or is there an easier way. Thanks in advance.

• Download and write .tar.gz files without corruption.

  - by arbales

  I've tried numerous ways of downloading files, specifically .zip and .tar.gz, with Ruby and write them to the disk. I've found that the file appears to be the same as the reference (in size), but the archives refuse to extract. What I'm attempting now is: Thanks! def download_request(url, filePath:path, progressIndicator:progressBar) file = File.open(path, "w+") begin Net::HTTP.get_response URI.parse(url) do |response| if response['Location']!=nil puts 'Direct to: ' + response['Location'] return download_request(response['Location'], filePath:path, progressIndicator:progressBar) end # some stuff response.read_body do |segment| file.write(segment) # some progress stuff. end end ensure file.close end end download_request("http://github.com/jashkenas/coffee-script/tarball/master", filePath:"tarball.tar.gz", progressIndicator:nil)

• Script.PostDeployment.sql not executing in CI build VS 2010

  - by Suirtimed

  I have a database project in VS 2010 (SQL 2008). The local Deploy Solution action works and executes all of the SQL in the Script.PostDeployment.sql file. When I check changes in, the Build Definition for the continuous integration server executes. The database is deployed into the CI environment, but the PostDeployment script doesn't get executed. I wasn't able to find anything specific to this particular scenario. I also expect I'll need to provide additional information unless this is a trivial problem that I missed somewhere. Additional Information: The build is executing vsdbcmd.exe to deploy. The deployment manifest references the PostDeployment.sql file and it's present in the path with the rest of the files. Here is a reference to a thread on social.msdn.microsoft.com regarding this problem.

• ActionScript/Flex: Augment MouseEvents with extra information

  - by David Wolever

  I've got a business class, Spam and the corresponding view class, SpamView. How can I augment MouseEvents coming out of SpamView so the MouseEvents which come out of it contain a reference to the instance of Spam which the SpamView is displaying? Here's how I'd like to use it: class ViewContainer { ... for each (spam in spams) { addChild(new SpamView(spam)); ... function handleMouseMove(event:MouseEvent) { if (event is SpamViewMouseEvent) trace("The mouse is being moved over spam:", spam) } } Thanks! Things I've considered which don't work: Adding event listeners to each SpamView: the book keeping (making sure that they are added/removed properly) is a pain. Using event.target: the event's target may be a child of the SpamView (which isn't very useful) Listening for a MouseEvent, creating a new SpamViewMouseEvent, copying all the fields over, then dispatching that: copying all the fields manually is also a pain.

• Git: How to find all commits in branch A that originated in derived branch B merged back into A?

  - by Michael Ludwig

  In Git, given (1) a branch A and (2) a branch B derived from A at some point in the past and then merged back into A, how can I find all the commits now in A that originated in B? The intent is to identify the changeset of work performed in B now in A to more quickly track down issues. A squash commit would obviously and conveniently pack the entire changeset in one commit for easy reference, but the drawbacks (such as loss of information and individual attributability) make this option undesirable for us. Hence my question.

• MVC (model-view-controller) - can it be explained in simple terms?

  - by DVK

  I need to explain to a not-very-technical manager the MVC (model-view-controller) concept and ran into trouble. The problem is that the explanation needs to be on a "your grandma will get it" level - e.g. even the fairly straightforward explanation offered on MVC Wiki page didn't work, at least with my commentary. Does anyone have a reference to a good MVC explanation in simple terms? It would ideally be done with non-techie metaphor examples (e.g. similar to "Decorator pattern is like glasses") - one reason I failed was that all MVC examples I could come up with were development related. I once saw a list of pattern explanations but to the best of my memory MVC was not on it. Thanks!

• How do I retrieve readonly values when using a DetailsView control to update a record?

  - by lincolnk

  I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection. I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?

• WCF: generic list serialized to array

  - by OpticalDelusion

  So I am working with WCF and my services return types that contain generic lists. WCF is currently converting these to arrays over the wire. Is there a way I configure WCF to convert them back to lists afterwards? I know there is a way by clicking advanced when you add a service reference but I am looking for a solution in configuration files or something similar. [DataContract(IsReference = true)] public class SampleObject { [DataMember] public long ID { get; private set; } [DataMember] public ICollection<AnotherObject> Objects { get; set; } } It is very odd, also, because one service returns it as a list and the other as an array and I am pretty sure they are configured identically.

• How to obtain specific Excel object library without the corresponding Office version installed.

  - by james-h-l

  I am developing a Excel automation app that read and write to Excel spreadsheet. I have Office 2007 installed on my machine. I therefore can reference the Excel 12.0 Object Library and the Excel 5.0 Object Library. I don't want to use Excel 5.0 because it's really quite old and poorly documented. Therefore I'm referencing Excel 12.0. However the target machine have Office 2003 installed and therefore only have Excel 11.0. So when I compile my program it crashes on the target machine since the referenced library are different. I was wondering is there a way I could obtain the Excel 11.0 without installing Office 03? I tried to find answers from msdn and microsoft support page but couldn't find anything? This is quite strange since it could also happen in the future where developers has newer editions of Office than clients?

• Python grab class in class definition.

  I don't even know how to explain this, so here is the code I'm trying. class Test: type = self.__name__ #self doesn't work, how do I get a reference to Test? class Test2(Test): pass #Test2.type should return "Test2" The reason I'm even trying this is I'm working on creating a base class for an orm I'm using. I want to avoid defining the table name for every model I have. Also knowing what the limits of python is will help me avoid wasting time trying impossible things.

• c# object initializer complexity. best practice

  - by Andrew Florko

  I was too excited when object initializer appeared in C#. MyClass a = new MyClass(); a.Field1 = Value1; a.Field2 = Value2; can be rewritten shorter: MyClass a = new MyClass { Field1 = Value1, Field2 = Value2 } Object initializer code is more obvious but when properties number come to dozen and some of the assignment deals with nullable values it's hard to debug where the "null reference error" is. Studio shows the whole object initializer as error point. Nowadays I use object initializer for straightforward assignment only for error-free properties. How do you use object initializer for complex assignment or it's a bad practice to use dozen of assigments at all? Thank you in advance!

• How can I create numbered map markers in Google Maps V3?

  - by kaneuniversal

  I'm working on a map that has multiple markers on it. These markers use a custom icon, but I'd also like to add numbers on top. I've seen how this has been accomplished using older versions of the API. How can I do this in V3? *Note -- the "title" attribute creates a tooltip when you mouseover the marker, but I want something that will be layered on top of the custom image even when you're not hovering on top of it. Here's the documentation for the marker class, and none of these attributes seem to help: http://code.google.com/apis/maps/documentation/v3/reference.html#MarkerOptions Thank you . . . . Michael

• Shallow Copy in Java

  - by Vilius

  Hello there! I already know, what a shallow copy is, but I'm not able to impliment it. Here's a short example. public class Shallow { String name; int number; public Shallow (String name, int number) { this.name = name; this.number = number; } } Test the implementation ... public class ShallowTest { public static void main (String[] args) { Shallow shallow = new Shallow("Shallow", 123); Shallow shallowClone = new Shallow(shallow); shallowClone.name = 'Peter'; shallowClone.number = 321; System.out.println(shallow.name + " - " + shallow.number); } } As I purpose, just the reference of the non primitive datatype String would be copied, so that by calling "shallowClone.name = 'Peter';" I would also change the name of "shallow". Am I right? But somehow, it just does not want to work ....

• Windows Identity Foundation - Local STS on Windows Azure.

  - by joe

  Hello, I am trying to use Federated authentication on Azure. I found a example of having a local sts outside azure which is used for authentication from a web role hosted in azure. This works perfectly. My issue is, i dont want to have an application outside azure. Instead, I want to host the local sts website also in azure. So in effect I will have two web roles (1. my actual website, 2. the sts). I tried the above approach my creating a new webrole and moving the files from my original sts project. But i am getting compilation errors even if I reference the required dlls. I have also set "copy local" to true. It will be very helpful if somebody can guide me.. Thanks

• J2ME app to access incoming call - Where to start?

  Here's my requirement: I often receive calls from unidentified numbers on my mobile phones. I would like an application which would use a reference list like this, and show me the carrier name and the area of origin along with the number on screen. Mobile make : Sony Ericsson Model : C902 Operating System: Propreitary J2ME: MIDP 2.0 Here are my questions: Is it possible to do something like this? I have installed a lot of java apps on my mobile, and all of them have to be launched seperately, can be run in the background, but they never seem to access anything native. If it is possible, which area of J2Me should I start with, for creating an application that achieves the above requirement? If it is not possbile, what are my alternatives?
