• Data import wizard library for .Net?

  - by Phil

  Does anyone know of a 3rd party data import wizard that can be embedded into applications? It should import from Excel, Access, SQLServer, csv, tab-separated flat file, XML, Oracle etc. We have a fixed data structure within our application and the user should be able to configure the wizard to match his/her import fields to our own data structure. The wizard should be a library of sorts – preferably a .Net type library. We may want to have it both web-based and desktop based (hence we may need an ASP.Net controls version and a Winforms version). We may also want integration with WPF and Silverlight. If there’s no UI wizard available, does anyone know of a non-UI library that supports easily configurable import from many, many different datasources?

• Is there any way to get MSVC to pass structs arguments in registers on x64?

  - by Luke

  For a function with signature: struct Pair { void *v1, *v2 }; void f(Pair p); compiled on x64, I would like Pair's fields to be passed via register, as if the function was: void f(void *v1, void *v2); Compiling a test with gcc 4.2.1 for x86_64 on OSX 10.6, I can see this is exactly what happens by examining the disassembly. However, compiling with MSVC 2008 for x64 on Windows, the disassembly shows that Pair is passed on the stack. I understand that platform ABIs can prevent this optimization; does anyone know any MSVC-specific annotations, calling conventions, flags, or other hacks that can get this to work? Thank you!

• jQuery - Iframe validation - cannot get values

  - by Henry

  See demo: http://tinyurl.com/3xow97t The editor is under development. Now we check if it has an value - this works well with all form fields that have the class .required... but it does not work with the iframe. the iframe has a div with id #content. $('form .meet').focus(function() { $('iframe').each(function() { ** if($(this).contents().find('#content').val() == '') { ** $(this).addClass('warning'); } }) }); That means it should add the class .warning if the iframe is empty. But it always does, so what am i doing wrong? Does it not work, because the JS does not see the text i currently typed in? ^^ Regards Henry

• Java Memory Overhead

  - by flamealpha

  Hello, I would like to ask about Memory Overhead in java, I have a large ArrayList (61,770 items), and trying to calculate the amount of memory taken by each item (counting the object and its ArrayList entry), by profiling the app i get that after all the data is loaded, the heap takes ~ 25Mb. when the ArrayList has only 2 items the heap takes ~1Mb , so roughly: (24*1024*1024)/61,768 = 407 bytes. however, when i count the fields of the each object, i get 148 bytes(not including the ArrayList, and assuming int=4,float=4,reference=4), I am curious to know where did all of those extra bytes came from... i can guess that since the objects I store in the ArrayList are implementing an interface, they store extra values, maybe the VM stores a 4byte function pointer for each implemented method? the interface they implement have 20 functions so thats 80 more bytes, totaling 228 bytes, still not close to the 400 bytes measured. any help would be appreciated.

• How to add request validation errors to ModelStateDictionary in ASP.NET MVC?

  - by Morten Christiansen

  Investigating the security of a system I'm building with ASP.NET MVC 2 led me to discover the request validation feature of ASP.NET - a very neat feature, indeed. But obviously I don't just want to present the users with the Yellow Screen of Death when they enter data with HTML in, so I'm out to find a better solution. My idea is to find all the fields that have invalid data and add them to the ModelStateDictionary before invoking the action such that they automatically appear in the UI as error messages. After googling this a bit it appears that no one have implemented this before which I find puzzling since it seems so obvious. Does anyone here have a suggestion on how to do this? My own idea is to supply a custom ControllerActionInvoker to the controller, as described here, that somehow checks for this and modifies the ModelStateDictionary but I'm stuck on how to do this last bit. Just catching HttpRequestValidationException exceptions does not seem a useful approach since it does not actually contain all the information I need.

• Why does Chrome incorrectly determine page is in a different language and offer to translate?

  - by Sam

  The new Google Chrome auto-translation feature is tripping up on one page within one of our applications. Whenever we navigate to this particular page, Chrome tells us the page is in Danish and offers to translate. The page is in English, just like every other page in our app. This particular page is an internal testing page that has a few dozen form fields with English labels. I have no idea why Chrome thinks this page is Danish. Does anyone have insights into how this language detection feature works and how I can determine what is causing Chrome to think the page is in Danish?

• iPhone Options for reading item from XML?

  - by fuzzygoat

  I am accessing this data from a web server using NSURL, what I am trying to decide is should I read this as XML or should I just use NSScanner and rip out the [data] bit I need. I have looked around the web for examples of extracting fields from XML on the iPhone but it all seems a bit overkill for what I need. Can anyone make any suggestions or point me in the right direction. In an ideal world I would really like to just specify [data] and get a string back "2046 3433 5674 3422 4456 8990 1200 5284" <!DOCTYPE tubinerotationdata> <turbine version="1.0"> <status version="1.0" result="200">OK</status> <data version="1.0"> 2046 3433 5674 3422 4456 8990 1200 5284 </data> </turbine> any comments / ideas are much appreciated. gary

• NetBeans not finding JasperReports scriptlet

  - by Sean

  I'm using JasperReports 3.7.6 with NetBeans 6.9.1 and iReport 3.7.6. I have a report that uses scriptlets. When I run it from iReport everything is fine because I can tell iReport where to find the .jar file with the scriptlets. When I run that same report from a JSF-2.0 application the fields that rely on the scriptlet are not being populated correctly - i.e. the scriptlet isn't being called. I've tried putting the scriptlet in the project's library folder and I've tried copying the package containing the scriptlet into the project. Neither has worked. I'm not sure how I can get the report to call the scriptlets when it is run from my JSF project. Can anyone shed some light on this for me?

• Turn RSS into array, explode the 'description' and insert words into MySQL table one per row

  - by K.I

  I have only recently gotten into php and MySQL and I want to take an RSS feed, turn it into an array, take only the description part of the XML, explode it and insert it into a table on a MySQL base. I feel like this should be possible, but is a little over my head right now. I tried using magpie as a parser, but if possible I want to do it in simpler php code. The result I am looking for would take a description "This is a cat" and insert it into a table with two fields ID term 1 This 2 is 3 a 4 cat I've been stumped on this for a couple days. Any help would be great.

• Imports and Depends

  - by David Diez

  I have read two recent posts that discuss Depends and Imports but I have four lingering, related questions: Suppose I want two packages to also be available to the end-user when they load in my package. Is there a good reason not to use Depends in this context? (The point here is to load all three packages via a command that loads just the one package.) Is it okay to specify a package in both the Depends and Imports fields? If a package is listed in Depends, is there a point to also listing it in Imports? Or are the benefits of Imports already negated by using Depends? [Added Question] Is the following correct? A package should be listed in the Imports field of the DESCRIPTION file if and only if the package is imported (in whole or in part) in the NAMESPACE file. Thanks much! David

• Lucene search taking TOOO long.

  - by Josh Handel

  I;m using Lucene.net (2.9.2.2) on a (currently) 70Gig index.. I can do a fairly complicated search and get all the document IDs back in 1 ~ 2 seconds.. But to actually load up all the hits (about 700 thousand in my test queries) takes 5+ minutes. We aren't using lucene for UI, this is a datastore between processes where we have hundreds of millions of pre-cached data elements, and the part I am working on exports a few specific fields from each found document. (ergo, pagination doesn't make since as this is an export between processes). My question is what is the best way to get all of the documents in a search result? currently I am using a custom collector that does a get on the document (with a MapFieldSelector) as its collecting.. I've also tried iterating through the list after the collector has finished.. but that was even worse. I'm open to ideas :-). Thanks in advance.

• Save a binary file in SQL Server as BLOB and text (or get the text from Full-Text index)

  - by Glennular

  Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions. Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types? -or- Is there a way to pull out the raw text from the Full text index? Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

• Variable for the field name of mysql row result

  - by ana

  I'm retrieving a row with php from mysql and it has fields like: name_en, name_es, name_de... I want to retrieve the right field base on my $lang variable (en, es, de...).

• ASP.NET MVC 2.0 Client-Side Validation HOWTO

  - by AlexWalker

  Where can I find some good information on the new client-side validation functionality included in ASP.NET MVC v2? I'd like to find information about using the client-side validation JavaScript without using DataAnnotations, and I'd like to find out how custom validations are handled. For example, if I want to validate two fields together, how would I utilize the provided JavaScript? Or if I wanted to write validation code on the server-side that queried a database, how could I use the provided JavaScript to implement a similar validation? I don't see any books on MVC2 yet, and the blog entries I've found are not detailed enough.

• Setting a cell's format using Excel 2007 Interop and C#

  - by CVertex

  I'm using the office 2007 interop assemblies to create some excel spreadsheets. There are plenty of questions on here about getting started and MSDN contains heaps of articles, like this one. The API is funky, and sometimes a bit confusing. When I set a value of a cell, is there a way to set it's format? I'd like to mark particular fields as Date's so my customer can run excel macros on them. Also, numbers would be useful. Thanks!

• mysql fulltext search as level2 index

  - by Nir

  lets say I have a table with product details. one of the fields is category (integer). I want to do fulltext search on product name in specific category. Unfortunately Mysql does not allow me to specify index that includes category and product name as fulltext. It looks like I can use fulltext only on product_name and theefore any fulltext search will search product names in all categories. Is there any way to solve this (allow fulltext search/index only on products in category)?

• HTML Form Upload PDF with other form contents using PHP

  - by Sev

  I have a HTML form with fields such as name, address, notes, etc. I also have a field to upload a PDF. The uploaded PDF get's stored on the file system. How can I accomplish this if possibly the PDF files are larger than 2 MBs? Also, for some reason, the uploading of the PDF (< 2 MBs) works fine in Chrome, but not in IE. In IE, the upload doesn't even begin, but in Chrome, it completes fine. Form header looks like: method='post' ENCTYPE='multipart/formdata' edit: the ini setting didn't help The HTML <input type='text' name='user' /> <input type='file' name='userfile' /> The basic PHP ( I do some preg matching above, that I haven't included) $uploaddir = 'uploads/'; $uploadfile = $uploaddir . basename($_FILES['userfile']['name']); if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) { echo "File is valid, and was successfully uploaded.\n"; } else { echo "File uploading failed.\n"; }

• Modal View Controller with keyboard on landscape iPad changes location when dismissed

  - by Roi

  I present a modal view controller on my on my iPad with UIModalPresentationFormSheet presentation style and UIModalTransitionStyleCoverVertical transition style. The Modal View Controller contains a UIWebView with some TextFields on it. When the user taps one of the text fields the keyboard comes up. I have noticed that in landscape mode after the keyboard is shown, if I try to dismiss the modal view controller with animation the view changes its position from the center of the screen to the left side just before the animation starts.. This happens only if the keyboard is up and only in landscape mode on the iPad. If the user closes the modal view without pressing on any text field this doesn't happen. Anyone familiar with this strange behavior?

• Data sync solution?

  - by user321088

  For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

• iTunes Music Store Link Maker — how to search from within my app?

  - by prendio2

  I'm writing a music reference app and for each album (pulled from last.fm) would like to link to the ITMS (if the album is in the store). iTunes link maker web tool http://apple.com/itunes/linkmaker/ is great for getting links for a known album but I need to access it programatically from within my app. This NSLog blogpost which is from 2003 but was referenced more recently in another question here seems to offer the only solution I've come across so far, suggesting to submit a query to: phobos.apple.com/WebObjects/MZSearch.woa/wa/advancedSearchResults? Put "itms://" before it and the link will work in iTunes, put "http://" before it and the link will work in Camino (Safari sometimes spits back a malformed XML error). The tags that are of importance are as follows: songTerm - song title artistTerm - artist name albumTerm - album name composerTerm - composer name term - all fields The suggestion is that would using http:// rather than itms:// the server will return an XML document of results instead of opening iTunes but either way I am sent directly to iTunes. Is it possible to get back a list of results?

• How to disable listbox's click event

  - by StupidDeveloper

  I have a listbox which acts as a list of items. If you click on some item, it's contents are shown in the panel on the right (few textboxes etc.). I need to have a validation on these controls as all of them are required fields. And I do have it. The problem is that, even when the validators are not valid, user can click the listbox and change active index (that doesn't have impact on the panel on the right, as SelectedIndexChanged isn't fired). The validators are standard RequiredFieldValidator with their Display property set to "Dynamic". So, what I want is to disallow the user clicking on the listbox and changing the index untill all validators are Valid. What would be your solution for that? Is that even possible?
