• Listview Cancel/Update causes Failed Veiwstate Error

  - by ChiliYago

  I am utilizing a asp.net Listview control which is causing a Failed to load viewstate error after a row is put in edit mode and the user clicks either update or cancel. The ListView control is in an ascx User control that is hosted in a parent aspx page. The parent aspx code-behind calls the a bind method on the ascx page which in turn binds the ListView. I am trying to isolate where and how this is happening but have not had any success and frankly I am out of ideas. Please offer some suggestions on what I should be looking at. Thank you.

• Knockout.js nested sortable bindings

  - by user2391998

  I am working with the knockout.js sortable plugin; however, I ran into a problem that I have so far been unable to solve. I have two sortable bindings, one for buckets and another for bucketItems. I am able to reorder bucketItems between buckets and between buckets; however, I am unable to reorder buckets. Would you have any idea why this would be? I am also using nested with bindings, but as far as I can tell, this is not what is causing problems. I would greatly appreciate any insight you have to offer. Thank you so much for your time!

• Reporting framework for extending definition & execution to the end users (ASP.Net)

  - by Kabeer

  Hello. My application is a product which will have reporting capabilities. The product, when in production, is expected to have several ad-hoc report defined by the end users. I am looking for a platform that can be tailored to harness the business entities and extend reporting capabilities (definition & execution) to the end user. Here are some constraints: From the usability standpoint, I like what MS Access reports offer. But of course it is not suitable for the target web application. However, it certainly is a source of inspiration usability wise. Cost is a constraint. So something recommended from open source world will be appreciated. Otherwise too I'd like to know. The product in question is somewhat 'generic' in nature. Mine is a ASP.Net platform.

• How to change out-of-focus text selection color in Xcode?

  - by Jackson

  Okay, I'll bite. I've got really pleasant code/window colors set up in Xcode. Ordinarily, my selection color is very visible. When I am doing a project search and iterating through the results, however, the results list stays in focus and the found text remains out of focus, using a different background color. This color is extremely hard to detect, especially when the text is embedded in a larger code block and the view is shifting around as it scrolls to the results. Here's an example: Left side is in focus (just normal selection), right side is out of focus (during project find) Often it takes a few seconds to find where the heck the selected text is. Unless I'm just missing it, Xcode seems to offer no way to change this particular selection color. Interestingly, it also doesn't seem to follow the selection color from the Appearance panel. Does anyone know a way to change this color or force it to be more visible, short of changing my entire color scheme around?

• WPF data grid for financial style reporting?

  - by user191254

  Hello, I'm looking for a decent WPF data grid or solution involving one to represent financial data. I've looked at many - the WPF one, XCeed, Ingragistics, DevExpress, etc.... but none of them seem to offer the simple requirement I have: I want to be able to display group subtotals in their columns in the group row, e.g. GROUP 1 xxxx.xx GROUP 2 xxxx.xx ROW 1 xx.xx ROW 2 xx.xx Does anyone know of a grid that does this, or a nice supporting collection that implements aggregate functions (group totals would need to be used in individual line items) so that existing grids with a bit of XAML styling would work? Thanks in advance, Stephen

• API access to a manually-created Google Map

  - by rutherford

  I have a number of public custom Google Maps created via http://maps.google.com/ - obviously associated with my google account. Can I access these maps via the Google Maps javascript api? The api doesn't appear to work with the manually created maps located on maps.google.com from what I can tell? And if not, is there another way to store overlay data (markers, etc) that the javascript api can grab and load into the map on the client's browser? Am thinking a service like dabbleDB, except that I don't think they offer write access via javascript (this would be necessary for the user adding markers to the map, for example) Obviously I could create a db layer on my server, but am looking for a 'cloud' solution that removes the strain from my databases!!

• SVG drawing application with vector export

  - by Bram Jetten

  I want to create a drawing application where I can place text and images on a canvas. Those elements also need to be interactively manipulated. Eventually the resulting canvas has to be exported to a vector based PDF. An excellent contender for this functionality would be SVG. However, this application also needs to be crossbrowser compatible. I've been browsing around for some time now and have seen a couple of solutions available. I found among others RaphaelJS and Google's SVGWeb for working with SVG. Now for converting those SVG files to a PDF I'm not sure if for instance Batik will offer me what I am looking for. Also, how would bitmap images be handled when converting the SVG to PDF?

• Efficiency of while(true) ServerSocket Listen

  - by Submerged

  I am wondering if a typical while(true) ServerSocket listen loop takes an entire core to wait and accept a client connection (Even when implementing runnable and using Thread .start()) I am implementing a type of distributed computing cluster and each computer needs every core it has for computation. A Master node needs to communicate with these computers (invoking static methods that modify the algorithm's functioning). The reason I need to use sockets is due to the cross platform / cross language capabilities. In some cases, PHP will be invoking these java static methods. I used a java profiler (YourKit) and I can see my running ServerSocket listen thread and it never sleeps and it's always running. Is there a better approach to do what I want? Or, will the performance hit be negligible? Please, feel free to offer any suggestion if you can think of a better way (I've tried RMI, but it isn't supported cross-language. Thanks everyone

• Creating a personal URL for all users to my site

  - by Abs

  Hello all, When a user registers with my site I want to offer them a login page and a user area with the URL: http://user1.mysite.com http://user2.mysite.com http://user3.mysite.com ... I did a google search for this but I wasn't sure of the right terms... How can I do this without having to actually create lots of subdomains - I am sure its not done this way - is it URL re-writing? Apache mod_rewrite? If so can someone give me an example please or is there a better way of doing this? Btw, I am using Codeigniter - if Codeigniter has something that can do this, I would rather use that. Thanks all for any help

• Move entire line up and down in Vim

  - by guy.incognito

  In Notepad++, I can use ctrl + shift + up/down to move the current line up and down. Is there a similar command to this in Vim? I have looked through endless guides, but have found nothing. If there isn't, how could I bind the action to that key combination? Edit: Mykola's answer works for all lines, apart from those at the beginning and end of the buffer. Moving the first line up or the bottom line down deletes the line, and when moving the bottom line up it jumps two spaces initially, like a pawn! Can anyone offer any refinements?

• I dont understand how Westpac Payway API and NET works

  - by spirytus

  Been googling all day, reading numerous pdf's and still getting confused with the concepts of sending data to Payway system from Westpac (bank in Australia, link text). They offer access via API but also give access via what they call NET. The way I understand is that when client want to pay on my website, in case of NET, client gets to the page (hosted by a bank or hosted by me) where is provided with form to enter credit card info details. Then this form is submitted via normal POST call to Payway's specific https address. It is processed then and browser returns to url I specified as one of the parameters I sent in hidden field. In case of API story is similar, so user receives form, fills in the data and then data is send to my backend (not Payway's). My backend then calls payway API with data provided and once answer received returns confirmation page to the client. Is my understanding right? Please explain as I have a feeling I am missing something basic here.

• UIToolbar on top of navigation bar - black opaque doesn't blend

  - by z s

  I am trying to put a UIToolbar on the right side of a UINavigationBar, to add multiple buttons on that side. When I leave the tint of both to Default, they blend fine. But when I set both of them to BlackOpaque, they don't blend very well. I can see the edge of where the toolbar starts very clearly. I've tried this through IB and code. Same result in both cases. Anyone run into this before, or can offer some suggestions?

• PostScript versus PDF as an output format

  - by Brecht Machiels

  I'm currently writing a typesetting application and I'm using PSG as the backend for producing postscript files. I'm now wondering whether that choice makes sense. It seems the ReportLab Toolkit offers all the features PSG offers, and more. ReportLab outputs PDF however. Advantages PDF offers: transparancy better support for character encodings (Unicode, for example) ability to embed TrueType and even OpenType fonts hyperlinks and bookmarks Is there any reason to use Postscript instead of directly outputting to PDF? While Postscript is a full programming language as opposed to PDF, as a basic output format for documents, that doesn't seem to offer any advantage. I assume a PDF can be readily converted to PostScript for printing? Some useful links: Wikipedia: PDF Adobe: PostScript vs. PDF

• How to preserve whitespace indentation of text enclosed in HTML <pre> tags excluding the current indentation level of the <pre> tag in the document?

  - by Michael Barton

  I'm trying to display my code on a website but I'm having problems preserving the whitespace indentation correctly. For instance given the following snippet: <html> <body> Here is my code: <pre> def some_funtion return 'Hello, World!' end </pre> <body> </html> This is displayed in the browser as: Here is my code: def some_funtion return 'Hello, World!' end When I would like it displayed as: Here is my code: def some_funtion return 'Hello, World!' end The difference is that that current indentation level of the HTML pre tag is being added to the indentation of the code. I'm using nanoc as a static website generator and I'm using google prettify to also add syntax highlighting. Can anyone offer any suggestions?

• Intermittent issue - IIS offering to donwload ASPX file instead of executing

  - by Nataliya

  We're getting an intermittent problem with the homepage of our site when IIS will suddenly start offering to download the ASPX file instead of executing it. It happens about once a month, on a random basis. If I open the file in Notepad and re-save it (without making a single change to the code), IIS starts executing the script as normal and doesn't offer the download any more. I can't get my head round this, considering that we can't reproduce the problem. Also, I can't really play with it and test anything when the problem occurs as this is the homepage of the site and needs fixing asap. Any ideas what could be causing this? Files are written to the server over Filezilla FTP. Looks like the homepage is the only page affected. Server is Windows Server 2003, IIS 6.0 with all the latest patches (we actually run two of them, load balanced, and the problem can occur on either server on a random basis). Can't see anything in the Event logs or IIS log.

• Recommendations for an in memory database vs thread safe data structures

  - by yx

  TLDR: What are the pros/cons of using an in-memory database vs locks and concurrent data structures? I am currently working on an application that has many (possibly remote) displays that collect live data from multiple data sources and renders them on screen in real time. One of the other developers have suggested the use of an in memory database instead of doing it the standard way our other systems behaves, which is to use concurrent hashmaps, queues, arrays, and other objects to store the graphical objects and handling them safely with locks if necessary. His argument is that the DB will lessen the need to worry about concurrency since it will handle read/write locks automatically, and also the DB will offer an easier way to structure the data into as many tables as we need instead of having create hashmaps of hashmaps of lists, etc and keeping track of it all. I do not have much DB experience myself so I am asking fellow SO users what experiences they have had and what are the pros & cons of inserting the DB into the system?

• How can I copy a file from VMS to Windows and back again?

  - by Matt Joslin

  I am trying to copy C source files from a vms alpha to a windows machine to allow easier editing of the code. (VMS editor is just a text editor and it would be nice to have syntax highlighting etc) I can copy this across using Exceed FTP and this handles the issue of duplicate filenames with version suffix that vms has: File.c;1 File.c;2 Flle.c;3 But when I open a file I've transferred, all the line breaks have been lost and the entire file is just one line. Can anyone recommend a solution to this or offer any hints? Thanks in advance ps. I need to be able to copy the files back to vms and still maintain format.

• Choosing MooTools over Google closure?

  - by Shekhar

  I am in a process to select javascript library for our new web application. This app is not very UI heavy but has forms, reports, search, calendars, tabs and target multiple countries like most web apps. We are a tiny team. Biggest concern is maintainability and readability of the code. We are Python programmers. After evaluating many other javascript frameworks we have narrowed down to mootools and google-closure. We loved mootools syntax. It took us no time to learn. It's like Python. On other hand we were stumped seeing private/public in google closure. It's tempting to go for mootools however, I would love to hear from you about specific advantages these frameworks offer over each other.

• nHibernate: Query tree nodes where self or ancestor matches condition

  - by Famous Nerd

  I have see a lot of competing theories about hierarchical queries in fluent-nHibernate or even basic nHibernate and how they're a difficult beast. Does anyone have any knowledge of good resources on the subject. I find myself needing to do queries similar to: (using a file system analog) select folderObjects from folders where folder.Permissions includes :myPermissionLevel or [any of my ancestors] includes :myPermissionLevel This is a one to many tree, no node has multiple parents. I'm not sure how to describe this in nHibernate specific terms or, even sql-terms. I've seen the phrase "nested sets" mentioned, is this applicable? I'm not sure. Can anyone offer any advice on approaches to writing this sort of nHibernate query?

• PowerShell Script to Find and Replace for all Files with a Specific Extension

  - by Brandon

  I have several configuration files on Windows Server 2008 nested like such: C:\Projects\Project_1\project1.config C:\Projects\Project_2\project2.config In my configuration I need to do a string replace like such: <add key="Environment" value="Dev"/> will become: <add key="Environment" value="Demo"/> I thought about using batch scripting, but there was no good way to do this, and I heard that with PowerShell scripting you can easily perform this. I have found examples of find/replace, but I was hoping for a way that would traverse all folders within my C:\Projects directory and find any files that end with the '.config' extension. When it finds one, I want it to replace my string values. Any good resources to find out how to do this or any PowerShell gurus that can offer some insight?
