• Viewing Crystal Reports other than through custom developed webform or winform apps

  - by Andrew

  At work we currently have a custom in-house built winforms app for the business users to view reports. It has role-based security and several administrator functions. My boss is thinking about getting me to port this app to webforms. My question is, are there options other than custom built winforms and webforms apps for deploying/viewing/administrating Crystal Reports at an enterprise level (role-based security, easy report deployment, etc)? I'm thinking about third-party packages or perhaps applications provided by Microsoft/Business Objects/SAP? We are using Crystal Reports 11.5.

• Can a single solution hold projects from multiple repositories?

  - by cyclotis04

  I've begun setting up SVN repositories to store my code, and am wondering if a single Visual Studio solution can have projects from multiple repositories. I have a shared library with different helper functions, generic custom controls, etc, that are used by multiple projects, and hosted in its own repository. Then I have my project repository, which contains all of the program-specific code such as forms, etc. I know I could copy the shared library into the program's repository, then copy them back when I make changes, but I'd much rather keep them in different repositories so I can hit "Commit" and the general library commits to it's repository, and the program code commits to it. I'm currently using AnkhSVN, but if it's possible with other tools, I'll look into it. Preemptive clarification for all the "just use one repository" answers: The shared library is hosted in an online repository, viewable by anyone, but the program code is proprietary and resides on our office servers, so they need different repositories.

• Printing JTables without formatting of the original component

  - by EricR

  I'm writing an application which utilises tables which can be printed if the user so desires and I wish to print a JTable filled with data, except I haven't been able to find an option to remove the formatting; the printed tables looks like it does in the GUI (based on the system theme) which is making the table less readable and using excess ink. I wish to print the same data with clear formatting. Is there a way to do this straight from a JTable or is my best option simply to print to a file and have the use printer from there. Currently it functions through a viewer which gives the user some options for printing, and then it goes to the system's printer.

• Overwriting a core Wordpress function - should work but it doesn't

  - by Will Ashworth

  I'm trying to overwrite a core Wordpress function (found in media.php) using add_filter() in my theme's functions.php file. This should work accord to the blogs that I've come across, but for some reason I see no change whatsoever. #override what WP is trying to do to scaling images by default function my_image_hwstring($width, $height) { $out = ''; #if ($width) # $out .= 'width="'.intval($width).'" '; #if ($height) # $out .= 'height="'.intval($height).'" '; return $out; } add_filter('image_hwstring', 'my_image_hwstring', 1, 2); I prefer to not edit media.php manually because any Wordpress upgrades later will overwrite the changes we've made. The way I'm doing it is correct (I think) but isn't working as expected. Totally hung up on this and appreciate any responses. This is a weird one!

• return false for parent javascript function

  - by jeerose

  $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

• Strategy for developing namespaced and non-namespaced versions of same PHP code

  - by porneL

  I'm maintaining library written for PHP 5.2 and I'd like to create PHP 5.3-namespaced version of it. However, I'd also keep non-namespaced version up to date until PHP 5.3 becomes so old, that even Debian stable ships it ;) I've got rather clean code, about 80 classes following Project_Directory_Filename naming scheme (I'd change them to \Project\Directory\Filename of course) and only few functions and constants (also prefixed with project name). Question is: what's the best way to develop namespaced and non-namespaced versions in parallel? Should I just create fork in repository and keep merging changes between branches? Are there cases where backslash-sprinkled code becomes hard to merge? Should I write script that converts 5.2 version to 5.3 or vice-versa? Should I use PHP tokenizer? sed? C preprocessor? Is there a better way to use namespaces where available and keep backwards compatibility with older PHP?

• jquery ajax vs browser url

  - by danwoods

  Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

• Best place to check user authenticity in a back end module where all pages are only available to mem

  - by understack

  I've a backend module which could only be accessed by only authorized members. So I need to check authenticity for all actions and for all controllers. Currently I'm doing it inside preDispatch() functions inside controller classes. So it takes care of all the actions inside that controller. But still I've to do it for all controllers. Is there a place I could check it for all the controllers as well. So basically I want one place authenticity check for whole backend module. Can I do it in bootstrap?

• Should I use implicit conversions to enforce preconditions?

  - by Malvolio

  It occurs to me that I could use use implicit conversions to both announce and enforce preconditions. Consider this: object NonNegativeDouble { implicit def int2nnd(d : Double) : NonNegativeDouble = new NonNegativeDouble(d) implicit def nnd2int(d : NonNegativeDouble) : Double = d.v def sqrt(n : NonNegativeDouble) : NonNegativeDouble = scala.math.sqrt(n) } class NonNegativeDouble(val v : Double ) { if (v < 0) { throw new IllegalArgumentException("negative value") } } object Test { def t1 = { val d : Double = NonNegativeDouble.sqrt(3.0); printf("%f\n", d); val n : Double = NonNegativeDouble.sqrt(-3.0); } } Ignore for the moment the actual vacuity of the example: my point is, the subclass NonNegativeDouble expresses the notion that a function only takes a subset of the entire range of the class's values. First is this: A good idea, a bad idea, or an obvious idea everybody else already knows about Second, this would be most useful with basic types, like Int and String. Those classes are final, of course, so is there a good way to not only use the restricted type in functions (that's what the second implicit is for) but also delegate to all methods on the underlying value (short of hand-implementing every delegation)?

• using javascript setTimeout to see if div has loaded

  - by Matt

  I'm loading remote data using dynamic script tags and JSON. the remote page that I'm displaying on my website has a div in it that I use to load content into. The problem is the javascript functions do not see the div as the page loads because it is remote data. if I set a timeout of about 300 it usually works and my javascipt can see the div. But sometimes it takes longer and it breaks the javascript. I'm tring this: function load_content() { if(document.getElementById('remote_div')==null) { setTimeout('load_content()', 300); } else { document.getElementById('remote_div').innerHTML = 'Content goes here' } } but it just doesn't seem to work... what is wrong with it?

• Is there a design pattern for injecting methods into a class?

  - by glenn I.

  I have a set of classes that work together (I'm coding in javascript). There is one parent class and a number of child classes that are instantiated by the parent class. I have a number of clients of these classes that each need to add on one more methods to the parent or child classes. Rather than having each client inherit from these classes, which is doable but messy because of the child classes, I am having these clients pass functions into the parent class when they instantiate the main class. The main class creates the methods dynamically and the clients can call the methods like they were there all along. My questions are: is this a sensible thing to do? what would the design pattern be for what I am doing?

• converting GPS latitude/longitude from different formats to one format (in PHP)

  - by Dave

  Hi. i'm trying to built in support for locations in my application and i'm expecting users to be inputting gps coordinates in a variety of ways. I need to convert all of the below to: latitude - direction (N/s), degres, minutes, seconds; longitude (E/W) - degrees, minuts, seconds. Each user input will be in a single line. eg: 9.182, -39.140625 9.182 / -39.140625 9.182,-39.140625 9.182 -39.140625 21° 16' 674S[some_separator]27° 30' 318E 21 16 674S[some_separator]27 30 318E [some_separator] may be a single space as well... The final format needs to beas: latitude.direction = south latitude.degrees = 21 latitude.minutes = 16 latitude.seconds = 674 longitude.direction = east longitude.degrees = 27 longitude.minutes = 30 longitude.seconds = 318 (a) what is the simplest way of asking ordinary-non-tech users to input the GPS coordinate?s (b) how do i convert the above to the final format? any built in functions that handle these variations in data input? i've seen http://stackoverflow.com/questions/2548943/gps-format-in-php - but i need to handle a more varied input.

• Anyone using ASP.NET MembershipProvider with Nhibernate?

  - by JLago

  Hi, I'm trying to implement Membership controls in a mvc 2 application and i'm having trouble dealing with the MembershipUser class. I have my own data store (in Postgresql) and I'm using Nhibernate to deal with it from C#. The thing is, I have my own user class, but I can't use it with any provider I found that implements Membership, because all the functions return the predefined MembershipUser class and cannot return my own. I'm losing my mind here, is there any way i can work with this, or should I implement everything myself? thanks in advance!

• What is the fastest way to learn JPA ?

  - by Jacques René Mesrine

  I'm looking for the best resources (books, frameworks, tutorials) that will help me get up to speed with JPA. I've been happily using iBatis/JDBC for my persistence needs, so I need resources that will hopefully provide comparable functions on how to do things. e.g. how to I set the isolation level for each transaction ? I know there might be 10 books on the topic, so hopefully, your recommendation could narrow down to the best 2 books. Should I start with OpenJPA or are there other opensource JPA frameworks to use ? P.S. Do suggest if I should learn JPA2 or JPA1 ? My goal ultimately is to be able to write a Google App Engine app (which uses JPA1). Thanks Jacque

• Wowhead.com Site Framework

  - by Byran

  I'm building a community website (not WoW related) and am curious what, if any, framework(s) Wowhead may use. The general, non-WoW specific functions of the site are near identical to what I need. A few of the features I'm interested in are: Item page comments User/Account management Forums Blog Content Management Search box suggestion I'm sure allot of their site is custom built but I assume that some portions may be third-party solutions, like the forums and blog. I just don't want to reinvent the wheel if it's out there ready for me to make use of.

• Qt grabWindow coordinates shifted from GetCursorPos and GetWindowRect

  - by user1391

  In Qt, when I use the QPixmap::grabWindow(hwnd,x,y,h,w) function, the coordinates are shifted slightly, when compared to the coordinates using the windows api functions GetCursorPos and GetWindowRect. i.e. (0,0) from the point of view of GetCursorPos and GetWindowRect is at the very top left of the toolbar at the top of the window. But (0,0) for QPixmap::grabWindow is more "inside" (i.e. ignoring the window frame). How can I make these 2 coordinates consistent? Especially since the user might have different thicknesses for the window frame?

• How can you determine if Control.Visible is set via property or if the value is inherited

  - by JDMX

  I need to find a way to determine if the Visible property of a control is set via a property change or if is inheriting it value from its parent. Using the Reflector, I find that the functions this.GetVisibleCore() and this.GetState() are both internal methods so I cannot call them. The widgets themselves are created dynamically so I do not want to attach a method to the VisibleChanged event just after the creation of each widget so can try to monitor this property. If I have to, I guess I will but I am looking for something jsut a bit more elegant.

• how to develop domain specific language on top of another language ?

  - by sofreakinghigh

  say i found a good open source software/library written in python. i want to wrap some of the functions or methods that i have created into easy to understand language of my own. do porter_stemm(DOC) (the DSL) would be equivalent to the function or series of methods written in python. i want to create a DSL that is easy to learn, but need this DSL translated into the original open source software software. im not sure if i am clear here but my intention is: create an easy to learn code language that users can use to solve a problem in a certain niche. this simple language needs to be translated or compiled or interpretated via some middleware into the original open source software's language (python).

• How to run Erlang based robot? Is it possible to convert it into .hex and run over microcontroller?

  I am working on Erlang robotic project. I have made a wallfollower robot program which has two files 1. a C program to communicate with hardware(I think we can not directly use Erlang for this) and 2. Erlang program to call these functions. I want to know where(platforms) I can run this robot. Is it possible to run this robot over micro-controller(8051 or ARM7) based hardware? Is it possible to convert Erlang program into C code or directly into .hex file? If any one have any idea please help asap. Thanks.

• Extract a regular expression match in R version 2.10

  - by tovare

  Hi, I'm trying to extract a number from a string. And do something like this [0-9]+ on this string "aaaa12xxxx" and get "12". I thought it would be something like: > grep("[0-9]+","aaa12xxx", value=TRUE) [1] "aaa12xxx" And then I figured... > sub("[0-9]+", "\\1", "aaa12xxxx") [1] "aaa12xxx" But I got some form of response doing: > sub("[0-9]+", "ARGH!", "aaa12xxxx") [1] "aaaARGH!xxx" There's a small detail I'm missing Please advice :-) I'm using R version 2.10.1 (2009-12-14) Thanks ! Comments on the solution The best solution is to ignore the standard functions and install Hadley Wickham's stringr package to get something that actually makes sense. Kudos to Marek for figuring out how the standard library worked.
