• Delegate methods of NSTextField using NSNotification

  - by hekevintran

  I have an NSTokenField in a window. I am using it to store tags related to a Core Data object. Right now I have it set up such that I can add tags to the objects, but I cannot delete them. I need a delegate method on the NSTokenField that can let me know when the user has moved the focus out of the NSTokenField. Since NSTokenField is a subclass of NSTextField I figured that I could use its delegate methods. It has two that I think could be useful: - (void)textDidChange:(NSNotification *)aNotification - (void)textDidEndEditing:(NSNotification *)aNotification I set my controller class as the delegate of my NSTokenField and put both of these methods into my controller class. I put a basic NSLog into each of them and neither is triggered when I interact with the NSTokenField. I am guessing it has something to do with NSNotification. How do I activate these methods?

• Using a "vo" for joined data?

  - by keithjgrant

  I'm building a small financial system. Because of double-entry accounting, transactions always come in batches of two or more, so I've got a batch table and a transaction table. (The transaction table has batch_id, account_id, and amount fields, and shared data like date and description are relegated to the batch table). I've been using basic vo-type models for each table so far. Because of this table structure structure, though, transactions will almost always be selected with a join on the batch table. So should I take the selected records and splice them into two separate vo objects, or should I create a "shared" vo that contains both batch and transaction data? There are a few cases in which batch records and/or transaction records. Are there possible pitfalls down the road if I have "overlapping" vo classes?

• How to add SQL elements to an array in PHP

  - by DanLeaningphp

  So this question is probably pretty basic. I am wanting to create an array from selected elements from a SQL table. I am currently using: $rcount = mysql_num_rows($result); for ($j = 0; $j <= $rcount; $j++) { $row = mysql_fetch_row($result); $patients = array($row[0] => $row[2]); } I would like this to return an array like this: $patients = (bob=>1, sam=>2, john=>3, etc...) Unfortunately, in its current form, this code is either copying nothing to the array or only copying the last element.

• Setting up Windows Authentication In Reporting Services Using Kerberos

  - by Vineet

  Hi, I have yet another problem with Reporting services. Finally I was able to set the ball rolling, achieving success in configuring reporting services with a domain user account. Now I have a problem accessing the server from another machine (in the same domain) using Integrated Windows Authentication in IIS 6.0. I have never had problems with this on networks using NT Authentication, but this is the first time our network is set up to use Kerberos. Here are my IIS settings - Reports (Manager) & ReportServer Virtual directories under Default Website, Both these are configured to run with Integrated Windows Authentication..Anonymous access turned OFF. Reporting Services Windows Service runs under Network service account and Web Service under a domain user account. Note - If I turn on Basic Authentication, it works fine, exceeding all my expectations, but this is not something I want. Any help is appreciated. Thanks Vineet

• how does fgets internally works?

  - by Registered User

  Well it is a basic question but I seem confused enough. #include<stdio.h> int main() { char a[100]; printf("Enter a string\n"); scanf("%s",a); } Basically the above is what I want to achieve. If I enter a string James Bond then I want that to be stored in array a. But the problem is because of presence of a blank space in between only James word is stored. So how can I solve this one. UPDATE After the replies given below I understand fgets() would be a better choice. I want to know internal working of fgets as why is it able to store the string with space where as scanf is not able to do the same.

• retrieve comma delimited data from a field in using SQL

  - by Nichols

  I've created a form in php that collects basic information. I have a list box that allows multiple items selected (ie housing, rent, food, water). If multiple items are selected they are stored in a field called Needs seperated by a comma. I have created a report ordered by the persons needs. The people who only have one need are sorted correctly, but the people who have multiple are sorted exactly as the string passed to the database (ie. housing, rent, food, water) -- which is not what i want. Is there a way to seperate the multiple values in this field using SQL to count each need instance/occurance as 1 so that there are no comma delimitations shown in the results? CLICK FOR EXAMPLE

• pointer to member function question

  - by Steve

  Hello, I'm trying to replicate a template I've used before with a member function, and it isn't going very well. The basic form of the function is template<class T> T Convert( HRESULT (*Foo)(T*)) { T temp; Foo(&temp); //Throw if HRESULT is a failure return temp; } HRESULT Converter(UINT* val) { *val = 1; return S_OK; } int _tmain(int argc, _TCHAR* argv[]) { std::cout << Convert<UINT>(Converter) << std::endl; return 0; } For the life of me, I can't get this to work with a member variable. I've read up on their syntax, and I can't seem to figure out how to make it work with templates. The class would be something similar to class TestClass { HRESULT Converter(UINT* val) { *val = 1; return S_OK; } }

• Axis2 issue with comment in WSDL

  - by Sirs

  I'm using an Axis2 client to access an external Webservice, whose WSDL starts with the following content: <?xml version="1.0" encoding="UTF-8"?><!--Created by TIBCO WSDL--><wsdl:definitions xmlns:wsdl=... My call to sendReceive crashes with the following error: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'C' (code 67) in prolog; expected '<' The 'C' is the first character on the comment in the WSDL. Without that comment everything works fine, but as far as my knowledge of basic XML dictates that comment is correct. My question would be: Is this a bug in Axis2 or is the accessed WSDL malformed? Is there any way to prevent Axis2 from crashing under these circumstances?

Also, can any one recommend me a good article that gives basic guidelines on how to prevent such vunerabilites been expolited? Or any coding examples?

• How do I convert a windows forms app from C# to VB ?

  - by SLC

  I've been converting all kinds of other things, classes, interfaces, ASP.NET MVC apps, and WPF applications, but I am stumped as to how to convert a windows forms application, as the whole structure seems to be different. Does anyone have any advice on how to tackle this problem? I see essentially that you have two files, Form1.cs and Form1.Designer.cs. Literally translating them from C# to VB doesn't work because of some intricacies or other of how Visual Basic works. I think you /might/ be able to convert Form1.cs in this way, as it's just a constructor plus event handlers, but the designer contains the references to the controls etc. and I am not sure how to go about doing that. I am using Visual Studio 2010 Beta 2.

• MySQL - Sort on a calculated value based on two dates

  - by Petter Magnusson

  I have the following problem that needs to be solved in a MySQL query: Fields info - textfield date1 - a date field date2 - a date field offset1 - a text field with a number in the first two positions, example "10-High" offset2 - a text field with a number in the first two positions, example "10-High" I need to sort the records by the calculated "sortvalue" based on the current date (today): If today=date2 then sortvalue=offset1*10+offset2*5+1000 else sortvalue=offset1*10+offset2*5 I have quite good understanding of basic SQL with joins etc, but this I am not even sure if its possible...if it helps I could perhaps live with a single formula giving the same sort of effect as the IFs do....ie. before date1 = low value, after date2 = high value...

• What's the easiest way to use OAuth with ActiveResource?

  - by Barry Hess

  I'm working with some old code and using ActiveResource for a very basic Twitter integration. I'd like to touch the app code as little as possible and just bring OAuth in while still using ActiveResource. Unfortunately I'm finding no easy way to do this. I did run into the oauth-active-resource gem, but it's not exactly documented and it appears to be designed for creating full-on API wrapper libraries. As you can imagine, I'd like to avoid creating a whole Twitter ActiveResource API wrapper for this one legacy change. Any success stories out there? In my instance, it might be quicker to just leave ActiveResource rather than get this working. I'm happy to be proven wrong!

• Is there an easy way to convert C# classes to PHP?

  - by John

  I am used to writing C# Windows application. However I have some free hosted PHP web space that I would like to make use of. I have a basic understanding of PHP but have never used it's object oriented capabilities. Is there an easy way to convert C# classes to PHP classes or is it just not possible to write a fully object oriented application in PHP? Update: There are no reliance on the .NET framework beyond the basics. The main aim would be to restructure the class properties, variable enums, etc. The PHP will be hosted on a Linux server.

• Can a CWinApp be placed in a DLL?

  - by jmucchiello

  I'm updating some legacy apps to Visual Studio 10 and am in linker hell. All of these DLLs derive classes from CWinApp and use AfxGetApp() to get access to the object. When I link the DLLs I get unresolved externals that look like global static objects that would get pulled in by a normal app's main(): Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CException::classCException" (?classCException@CException@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CFrameWnd::classCFrameWnd" (?classCFrameWnd@CFrameWnd@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static class CRect const CFrameWnd::rectDefault" (?rectDefault@CFrameWnd@@2VCRect@@B) My current combination of ignore default libraries and additional libraries (the method you can easily google to find the answer to linker hell) is: msvcprtd.lib,mfc100d.lib,mfcs100d.lib,libcmtd.lib When I add nafxcwd.lib (the mfc library), these three external symbols resolve but I end up with a bunch of other duplicate symbols (requiring the use of /FORCE:MULTIPLE) and in end __argc and __argv become unresolved. So the basic question is: Can you link a DLL containing a CWinApp in VS10? How do you setup the linker to do it?

• Getting "longnamesfirst" option to work with natbib in LaTeX - custom .bst

  - by jkale

  Hey all, I'm writing an MSc dissertation and I'm having difficulty getting the longnamesfirst option working in natbib. My University has a very specific referencing style a little like APA, but not quite the same. I've used the docstrip utility to build a basic framework and then edited it to fit the requirements of my University. Having tested it with the simplest possible document; applying my bst then trying it again with one of the defaults (\bibliographystyle{apacite}) I can see than natbib works as intended with apacite. It doesn't however produce correct results with my bst. So my question: How does the .bst file link with natbib to enforce the "longnamesfirst" option?

• How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

  - by Ivan

  I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

• Using query parameter in Access report

  - by Dave

  I have a very basic access database where a query returns the sales made within a set start date and a set end date. The dates are set with two pop up boxes for the user to enter, first the start date, and then the end date. I have a report running off the back of this. How can I (using VBA) get at these dates then display them on the report - ie. the report says "Sales for Period:" and then shows the "from date" and the "to date" that the user input.

• Multiple Questions per page using Drupal Quiz

  - by Andrew

  I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

• Setting up a non-emacs Common Lisp Dev Env for web application development?

  - by Ravi S

  I am trying to set up a Common Lisp Dev Env for web application development on my Ubuntu 10.04 LTS 64-bit box and I can't find a single decent guide that is targeted at noobs. The closest I came is with Peter Seibel's Lisp in a box but I detest Emacs with a passion and it seems to have older versions of SBCL and CLISP (which are my preferred CL implementations). I do not want to use any of the commercial implementations. I am looking for a simple setup to write some very basic CRUD apps involving possibly hunchentoot, some framework like weblocks,CL-WHO, CL-SQl, sqlite or some datastores from the nosql family like mongo and couch.. Assuming, I go with either SBCL or CLISP on Linux, what is the best tool to manage packages and libraries? ASDF? I am looking for simplicity and consistency and I don't expect to use a ton of libs...

• drupal bootstrap script: how to get list of all nodes of type x?

  - by groovehunter

  hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

• How can I debug an application crash in Win7 after it's happened?

  - by parsley72

  I have a Visual Basic 6 application that I've recently changed to use a couple of C++ DLLs I've written in Visual Studio 2008. The application works fine on my PC, but when we install it on one of our test PCs it tends to crash during shutdown - we see the Win 7 message "Your application has failed" or whatever it is. I know Win 7 stores data that can be used to analyse the crash. I've got the source code and .PDB files from the build so I should be able to use that, but I can't figure out where Win 7 stores the data from the crash. The Event Viewer shows the crash but doesn't have any data and the directory C:\Windows\Minidump doesn't exist. Where do the crash files get put?

• Learning Spring MVC For web-projects

  - by John

  I have looked at Spring MVC a few times briefly, and got the basic ideas. However whenever I look closely it seems to require you already know a whole load of 'core Spring'. The book I have for instance has a few hundred pages before it gets onto Spring MVC... which seems a lot to wade through. I'm used to being able to jump in, but there's so much bean-related stuff and XML, it just looks like a mass of data to consume. Does it simplify if you put the time in, or is Spring just a much bigger framework than I thought? is it possible to learn this side of it in isolation?

• Import text file crunching library for Java/Groovy ?

  - by devdude

  In a lot of real life implementations of applications we face the requirement to import some kind of (text) files. Usually we would implement some (hardcoded?) logic to validate the file (eg. proper header, proper number of delimiters, proper date/time value,etc.). Eventually also need to check for the existence of related data in a table (eg. value of field 1 in text file must have an entry in some basic data table). While XML solves this (to some extend) with XSD and DTD, we end up hacking this again and again for proprietary text file formats. Is there any library or framework that allows the creation of templates similar to the xsd approach ? This would make it way more flexible to react on file format changes or implement new formats. Thanks for any hints Sven

• Inserting a table column with jQuery

  - by fudgey

  I have a table of data that I need to dynamically add a column to. Lets say I have this basic table to start with: <table> <tr><td>cell 1</td><td>cell 2</td><td>cell 3</td></tr> <tr><td>cell 1</td><td>cell 2</td><td>cell 3</td></tr> <tr><td>cell 1</td><td>cell 2</td><td>cell 3</td></tr> </table> I would like to insert a column between cell 1 and cell 2 in each row... I've tried this but it just isn't working like I expect... maybe I need more caffeine. $(document).ready(function(){ $('table').find('tr').each(function(){ $(this).prepend('<td>cell 1a</td>'); }) })
