• How to change to a grouped table view in xcode without using Interface Builder

  - by Dave

  I have a table that I created within xcode so there is no nib file in this case. I want to make my table into the 'Grouped' style but im not sure how. I think it has somthing to do with the method below, the problem is Im not really sure how to call it, I do understand how methods work I'm just not too sure on where to start with this one: - (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)UITableViewStyleGrouped So could someone tell me how to call it? The problem is that its not a method I wrote its a built in one so I could put that line into my header file but how would I use it in my implementation file? Thanks guys,

• jquery-Ajax call on tornado handlers waits for pervious ajax call to return

  - by harshh

  Hey All. I recently started testing TornadoWeb for a home-project, which uses jquery getJSON function to call my tornado handlers. And found something strange, which i seek an explanation for. I fire an ajax request for Handler1 on tornado, and in some cases request for Handler2 is initiated before Handler1 returns. It appears from development-server logs, and firebug console-debugging, that Handler2 request waits for Handler1 request to finish, and then return. So basically, XHR call is waiting for earlier XHRs. They are supposed to be asynchronous/non-blocking right?? Or am i missing something. You can check the test-case environment called testtornado at http://github.com/harshh/Harsh-Projects/ with main.py as server triggering file. I would appreciate help from anyone who can throw some light on this.

• nyroModal Window on flash background

  - by Lowgain

  I've got a Flex App running at 100% width and 100% height. The embed code is: <script type="text/javascript"> var fVars = {}; fVars.wmode = "transparent"; //also tried "opaque" swfobject.embedSWF("/swf/app.swf", "app", "100%", "100%", "9.0.0", "expressInstall.swf", fVars); </script> <div class="app"></div> I've also got the nyroModal call, which is essentially $.nyroModalManual({ url: urlPath, wrap: {}, closeButton: "" }); The modal window I am trying to open in this case is a div with some text and another flash embed, which works. I've also got the app div's z-index to 0. In Firefox this looks fine, everything works. In Chrome however, nyroModal's fade-in/transparent overlay does not show up, and only the second swf is visible overtop the background flash. Am I missing anything here? Is this a known issue with Chrome?

• Objective C: Create arrays from first array based on value

  - by Nic Hubbard

  I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

• How to implement lambda as a function called "lambda" in Clojure?

  - by dirtyvagabond

  I'd like to be able to define lambdas using common Lisp syntax, in Clojure. For example: (lambda (myarg) (some-functions-that-refer-to myarg)) This needs to result in the same as: #(some-functions-that-refer-to %) In my case, I know I'll always have exactly one arg, so perhaps that simplifies things. (But it can be called anything -- "myarg" or whatever.) I suspect a workable solution is to "(defmacro lambda ...". If so, I'm not sure of the best way to proceed. How to cleanly translate the arg name to %? And how to end up with the correct function? Or, is there a simpler solution than writing my own macro that actually re-implements Clojure's... lambda?

• Swipe gestures on Android ListView items

  - by Bartek

  I have a ListView populated by a ResourceCursorAdapter. I use the loaders mechanism to query a ContentProvider for list items. I detect swipe gestures on the list items to perform some actions on them. New items get added by a background service, so the list can change dynamically. Everything works fine, except when I start swiping and a database change occurs (as a result of the background service adding a new row). In such case the gesture is not detected properly. I noticed that ACTION_CANCEL is dispatched to the list item view and also that bindView is executed for all visible items. Inside the bindView method I only set some text - I don't change any listeners there. How can I make gestures work even when new items are being added by the background service? Perhaps there's a way to prevent the motion from being cancelled or I can pause database updates so they don't interrupt the gesture.

• Using Kate with Simple Build Tool (SBT)

  - by Stefan

  Hello I am working with the Kate editor based on the lack of other good tools for Scala development, I am also using IntelliJ however it still has some bugs, and are slow enough to make me impatient. I have just startet using both Kate and SBT, and in that regard I have a little challenge I hope there is an answer for out there on "The Internet". I am using the standard "Build plugin" in Kate and has changed the commands from make to sbt. This works fine, and I am also getting a error report when the sbt fails during compile time. However I really wish to know if it is possible to integrate the compile errors into Kate such that it would be shown under "Errors and Warnings" instead of just in the output tab, where I have to do a manual search for the compile errors. Im guessing that it has something to do with the format of the output, if that is the case maybe it is "just" a smaller adjustment I need to make to the parsing language.

• Dynamic query runs directly but not through variable, what could be the reason?

  - by waheed

  Here is my scenario, I'm creating a dynamic query using a select statement which uses functions to generate the query. I am storing it into a variable and running it using exec. i.e. declare @dsql nvarchar(max) set @dsql = '' select @dsql = @dsql + dbo.getDynmicQuery(column1, column2) from Table1 exec(@dsql) Now it produces the many errors in this scenario, like 'Incorrect syntax near ','' and 'Case expressions may only be nested to level 10.' But if i take the text from @dsql and assign it a variable manually like: declare @dsql nvarchar(max) set @dsql = '' set @dsql = N'<Dynamic query text>' exec(@dsql) it runs and generates the result, what could be the reason for that ?? Thanks..

• NServiceBus persisting subscriptions in Pub/Sub sample

  - by Bogdan Nedelcu

  I want to figure out how I to set up the Pub/Sub sample from NServiceBus to work in the case of publisher malfunction. When I start the samples and accidentaly close the Subscribers, if I restart everything works fine. If however I kill the publisher and the subscriptions continue to work, if I restart the publisher, then it doesn't seem to know it has subscribers and doesn't post any messages. I added the config entry <MsmqSubscriptionStorageConfig Queue="subscriptions"/> but it seems to not function... I miss something. I googled about MsmqSubscriptionStorageConfig and DbSubscriptionStorageConfig but i didn't find a solution. Could someone point me in the right direction ?

• Multidimensional arrays in VB.NET 2010

  - by matt_t

  Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.

• When to log exception?

  - by Rune

  try { // Code } catch (Exception ex) { Logger.Log("Message", ex); throw; } In the case of a library, should I even log the exception? Should I just throw it and allow the application to log it? My concern is that if I log the exception in the library, there will be many duplicates (because the library layer will log it, the application layer will log it, and anything in between), but if I don't log it in the library, it'll be hard to track down bugs. Is there a best practices for this?

• C# Winforms ADO.NET - DataGridView INSERT starting with null data

  - by Geo Ego

  I have a C# Winforms app that is connecting to a SQL Server 2005 database. The form I am currently working on allows a user to enter a large amount of different types of data into various textboxes, comboboxes, and a DataGridView to insert into the database. It all represents one particular type of machine, and the data is spread out over about nine tables. The problem I have is that my DataGridView represents a type of data that may or may not be added to the database. Thus, when the DataGridView is created, it is empty and not databound, and so data cannot be entered. My question is, should I create the table with hard-coded field names representing the way that the data looks in the database, or is there a way to simply have the column names populate with no data so that the user can enter it if they like? I don't like the idea of hard-coding them in case there is a change in the database schema, but I'm not sure how else to deal with this problem.

• I can't make this query work with SUM function

  - by Mehper C. Palavuzlar

  This query gives an error: select ep, case when ob is null and b2b_ob is null then 'a' when ob is not null or b2b_ob is not null then 'b' else null end as type, sum(b2b_d + b2b_t - b2b_i) as sales from table where ... group by ep, type Error: ORA-00904: "TYPE": invalid identifier When I run it with group by ep, the error message becomes: ORA-00979: not a GROUP BY expression The whole query works OK if I remove the lines sum(b2b_d+b2b_t-b2b_i) as sales and group by ..., so the problem should be related to SUM and GROUP BY functions. How can I make this work? Thanks in advance for your help.

• disable SSL on MAMP

  - by morktron

  Hi I'm used to editing sites locally on my MAMP to test out changes before going live. In this case though the site has a SSL certificate and wants to use it when I go to admin. So I can't go to admin. The error message says: (Error code: ssl_error_rx_record_too_long) It's a Joomla site I'm trying to log into locally ie: http://localhost:8888/site/administrator/ I've tried https as well, but same thing. Also same thing is Safari. I just need to turn off ssl, it must be a file somewhere in the site I downloaded.

• C++: Dependency injection, circular dependency and callbacks

  - by Jonathan

  Consider the (highly simplified) following case: class Dispatcher { public: receive() {/*implementation*/}; // callback } class CommInterface { public: send() = 0; // call } class CommA : public CommInterface { public: send() {/*implementation*/}; } Various classes in the system send messages via the dispatcher. The dispatcher uses a comm to send. Once an answer is returned, the comm relays it back to the dispatcher which dispatches it back to the appropriate original sender. Comm is polymorphic and which implementation to choose can be read from a settings file. Dispatcher has a dependency on the comm in order to send. Comm has a dependency on dispatcher in order to callback. Therefor there's a circular dependency here and I can't seem to implement the dependency injection principle (even after encountering this nice blog post).

• Asp.NET 1.1 HttpResponse headers

  - by Yeti

  Hi, i have part of Asp.NET 1.1 project. I work with remote site, which works incorrect in some cases - sometimes it write incorrect Content-Encoding header. In my code i get HttpResponse from this remote site. And if Content-Encoding header is equals, for example, "gzip", i need to set Content-Encoding header to "deflate". But there is no properties or methods in HttpResponse class to get Content-Encoding header. Content-Encoding property returns, in my case, "UTF-8". In Watch window i see _customProperties field, which contain wrong string value. How can i change header value with Asp.NET 1.1?

• Unix RPC programming

  - by Abhi

  Heyy all, I needed some help with ONC RPC programming. My task is to create two-tier client-server architecture wherein one main server (something like a directory) keeps a track of level-two servers and acts as a lookup; the level-two servers exposing some trivial functions, and finally, the clients for level-two servers. The clients ask the directory where a server is located, and then communicate with it. Using RPCGEN, we can create a pair of client-server code; however, the clients in this case need to have stubs for the directory as well as the level-two functions. Being a newbie to RPC, I'm having trouble conceptualizing the way I should code this. How can I call a function from a different server if a client is generated using a different IDL ? Any pointers would be appreciated :) Regards, Abhi

• How does the linux kernel manage less than 1GB physical memory ?

  - by TheLoneJoker

  I'm learning the linux kernel internals and while reading "Understanding Linux Kernel", quite a few memory related questions struck me. One of them is, how the Linux kernel handles the memory mapping if the physical memory of say only 512 MB is installed on my system. As I read, kernel maps 0(or 16) MB-896MB physical RAM into 0xC0000000 linear address and can directly address it. So, in the above described case where I only have 512 MB: How can the kernel map 896 MB from only 512 MB ? What about user mode processes in this situation? Where are user mode processes in phys RAM? Every article explains only the situation, when you've installed 4 GB of memory and the kernel maps the 1 GB into kernel space and user processes uses the remaining amount of RAM. I would appreciate any help in improving my understanding. Thanks..!

• POX return data from WCF Data Services

  - by keithwarren7

  I am using WCF Data Services (netfx4) to provide data sourced from SQL via EF, the standard OData mechanism is fine and JSON works as well but I need a third option for generic POX (plain old xml). I have yet to come across a simple strategy or switch that allows me to control this but I am sure one must exist or a workaround method might be available. Any ideas? Ideally I would like to be able to use something like the JSONP option wherein I append 'format=JSON' to the URL, in this case 'format=pox' or 'POX=true' or something of that nature.

• StreamReader ReadToEnd() after HttpWebRequest EndGetResponse() - most scalable?

  - by frankadelic

  I am calling a RESTful web service in the back-end of some ASP.NET pages. I am using ASP.NET asynchronous pages, so under the hood I am using the methods: HttpWebRequest BeginGetResponse() and HttpWebRequest EndGetResponse() The response string in my case is always a JSON string. I use the following code to read the entire string: using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream())) { myObject.JSONData = sr.ReadToEnd(); } Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits. Thanks, Frank

  - by masato-san

  I have parent window (opener) and child (popup) ---------- -------------- | | | | | parent | -----> opens popup | child | | | | | ----------- -------------- Let's say, in parent page, I have js function hello() In order for child to call parent's hello() when the child window is closed and also pass an argument, I can do, window.close(); window.opener.hello(someArgument); This will close the window and also call parent's hello(); But what if I don't want to have the code window.opener.hello() in child page? I mean I want the code to be in parent page only One thing I can think of is: Somewhat parent knows when the child is closed (event listenr??? not sure in js) But in such case how to receive the argument?

• How to fetch the data from binary log file and insert in our desired table in MySQL?

  How to fetch the data from binary log file and insert in our desired table in MySQL? I am on my way of scripting a PHP code for Audit Trail, in this I encountered a situation that if there will be new table created then I will not be available with triggers for that new table and hence no tracking could be done for that, so if I code it to create three new triggers for this new table, then how will get the last change done in this table? Hence I found that Binary Log File can be helpfull for me in this case, to fetch the last change for this new table and insert it in tracking table... BUT HOW????

• can't update rails model

  Hi there, I'm rather new to rails. I have a controller that's attempting to update a model using the following code: @test = Product.find(1) @test.increment!(:price) It does successfully retrieve the Product from the database, but does not update the price attribute. Does anyone know why this might be the case, or how I could get more feedback on what the problem is? Thanks a bunch! Tristan edit: price is an integer with value 0. I get the same problem when I set the price with @test.price=50 and then @test.save .
