Best approach for authorisation rules

- by Maciej

I'm wonder about best approach of implementation auth. rules in Client-Server app using Business Objects. I've noticed common tactic is: - on DB side: implement one role for application, used for all app's users - definition users right and roles and assign users to proper group - Client side: add to Business Object's getters/setters rights checker allowing write / display data for particular user My concern is if this is really good approach from security perspective. It looks DB sends all information to Client, and then client's logic decide what to display or not. So, potentially advanced user can make query from their box and see/change anything. Isn't it?

- by XBasic3000

I need create a programatic equivalent using delphi language... or could someone post a link on how to do grammars in peech recogniton using the delphi. sorry for my english... **Programmatic Equivalent C#:** Ref: http://msdn.microsoft.com/en-us/library/ms723634(v=VS.85).aspx To add a phrase to a rule, SAPI provides an API called ISpGrammarBuilder::AddWordTransition.

iPhone long plist

- by Zac Altman

I have some data i want to add in to my app...about 650 categories (includes a name + id number), each with an average of 85 items (each with a name/id number). Will the iPhone support such a large plist? I want to first display the categories in a UITableView, when a category is selected I want to display all of the associated items. Having such a large plist, im not sure if the iPhone will lag when loading the items. At over 51,000 lines it seems like...it might.

Reading custom values in Ebay RSS feed (XML::RSS module)

- by munster

I've spent entirely way too long trying to figure this out. I'm using XML:RSS and Perl to read / parse an Ebay RSS feed. Within the area, I see these entries: 1395 1255 However, I can't figure out how to grab the details during the loop. I wrote a regex to grab them: @current_price = $item =~ m/\(\d+)\<\/rx\:CurrentPrice/g; which works if you place the above 'CurrentPrice' entry into a standalone string, but not while the script is reading through the RSS feed. I can grab most of the information I want out of the item-description area (# bids, auction end time, BIN price, thumbnail image, etc), but it would be nicer if I could grab the info from the feed without me having to deal with grabbing all that information manually. If anybody knows how to grab custom fields from an RSS feed (short of writing regexes to parse the entire feed w/o a module), any help / insight would be appreciated.

How to deal with arrays of data in cookies

- by peter

Hi all, I want to store data in a cookie and I am not exactly sure how I will go about it. The data is the UserName, and Password values for the users that are logging into a website, e.g. sometime like this UserName = bob, Password=Passw0rd1 UserName = harry, Password=BLANK UserName = george, Password=R0jjd6s What this means is that bob and george logged into the site and chose to have their password remembered, but harry chose for his password not to be remembered. So on the login dialog a dropdown will be present with all the usernames in it 'bob', 'harry', 'george'. If they select the username bob the password will automatically be filled in, etc. So how does that information need to be stored in the cookie? Like it is above, or does it have to be, UserName1 = bob, Password1=Passw0rd1 UserName2 = harry, Password2=BLANK UserName3 = george, Password3=R0jjd6s Are the username and password values actually stored in the same cookie, or is each piece of data separate? Any information would be good.

iPhone UIWebView: loadData does not work with certain types (Excel, MSWord, PPT, RTF)

- by Thomas Tempelmann

My task is to display the supported document types on an iPhone with OS 3.x, such as .pdf, .rtf, .doc, .ppt, .png, .tiff etc. Now, I have stored these files only encrypted on disk. For security reasons, I want to avoid storing them unencrypted on disk. Hence, I prefer to use loadData:MIMEType:textEncodingName:baseURL: instead of loadRequest: to display the document because loadData allows me to pass the content in a NSData object, i.e. I can decrypt the file in memory and have no need to store it on disk, as it would be required when using loadRequest. The problem is that loadData does not appear to work with all file types: Testing shows that all picture types seem to work fine, as well as PDFs, while the more complex types don't. I get a errors such as: NSURLErrorDomain Code=100 NSURLErrorDomain Code=102 WebView appears to need a truly working URL for accessing the documents as a file, despite me offering all content via the NSData object already. Here's the code I use to display the content: [webView loadData:data MIMEType:type textEncodingName:@"utf-8" baseURL:nil]; The mime-type is properly set, e.g. to "application/msword" for .doc files. Does anyone know how I could get loadData to work with all types that loadRequest supports? Or, alternatively, is there some way I can tell which types do work for sure (i.e. officially sanctioned by Apple) with loadData? Then I can work twofold, creating a temp unencrypted file only for those cases that loadData won't like. Update Looks like I'm not the first one running into this. See here: http://osdir.com/ml/iPhoneSDKDevelopment/2010-03/msg00216.html So, I guess, that's the status quo, and nothing I can do about it. Someone suggested a work-around which might work, though: http://osdir.com/ml/iPhoneSDKDevelopment/2010-03/msg00219.html Basically, the idea is to provide a tiny http server that serves the file (from memory in my case), and then use loadRequest. This is probably a bit more memory-intensive, though, as both the server and the webview will probably both hold the entire contents in memory as two copies then, as opposed to using loadData, where both would rather share the same data object. (Mind you, I'll have to hold the decrypted data in memory, that's the whole point here).

Is DataGrid a necessity in WPF?

- by Jobi Joy

I have seen a lot of discussions going on and people asking about DataGrid for WPF and complaining about Microsoft for not having one with their WPF framework till date. We know that WPF is a great UI technology and have the Concept of ItemsControl,DataTemplate, etc,etc to make great UX. Even WPF has got a more closely matching control- ListView, which can be easily templated to give better UX than a traditional Datagrid like display. And I would say a readymade DataGrid control will kill or hide a lot of creativity and it surely will decrease the innovations in User Experience field. So what is your opinion about the need of DataGrid in WPF as a Framework component? If you feel it is necessary then is it just because the world is so used to the DatGrid way of data display for many years? Some other threads having the discussion about DatGrid are here and here Link to WPF ToolKit - Latest WPF DatGrid

Problem with displaying and downloading email attachments using the zend framework

- by Ali

Hi guys I'm trying to display emails in my inbox and their respective attachments. At the same time I also wish to be able to download the attachments however I'm kinda stuck here. Here is the code I use to display the attachments: $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); // get the contact of this message $email = array_pop(extract_emails_from($one_message->from)); $one_message->contactFrom = $contact_manager->get_person_from_email($email); $one_message->parts = array(); foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; $one_message->parts[$ii] = $tpart; // put the part of the message indexed with what I assume is its position if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); $h2t->set_html($b); $one_message->body = $h2t->get_text(); } if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); $one_message->body = $part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } And I display the attachments using the following link: ?action=download&element=email-attachment&box=inbox&uid=<?php echo $one_message->UID;?>&id=<?php echo $one_message->id;?>&part=<?php echo $ii;?> The part variable is the index taken from the loop above However when I try to download using the exact same code as above modified slightly: $id = $_GET['id']; $pid = $_GET['part']; $one_message = $mail->getMessage($id); foreach (new RecursiveIteratorIterator($mail->getMessage($id)) as $ii=>$part) { if($pid == $ii): $content = base64_decode($part->getContent()); $cnt_typ = explode(";" , $part->contentType); $name = explode("=",$cnt_typ[1]); $filename = $name[1];//It is the file name of the attachement in browser //This for avoiding " from the file name when sent from yahoomail $filename = str_replace('"'," ",$filename); $filename = trim($filename); header("Cache-Control: public"); header("Content-Type: ".$cn_typ[1]); header("Content-Disposition: attachment; filename=\"" . $filename . "\""); header("Content-Transfer-Encoding: binary"); echo $content; exit; endif; } For some reason it doesn't work at all. I did a var dump and noticed that in the for loop with the reverseiterator teh indexes $ii returned are 1 - 2 - 2 !! Whats going on here how can the indexes be repeated? How can I tell one part from the others?

Noob-Ready Cython Tutorials

- by spearfire

I know a bunch of scripting languages, (python, ruby, lua, php) but I don't know any compiled languages like C/C++ , I wanted to try and speed up some python code using cython, which is essentially a python - C compiler, aimed at creating C extensions for python. Basically you code in a stricter version of python which compiles into C - native code. here's the problem, I don't know C, yet the cython documentation is aimed at people who obviously already know C (nothing is explained, only presented), and is of no help to me, I need to know if there are any good cython tutorials aimed at python programmers, or if I'm gonna have to learn C before I learn Cython. bear in mind I'm a competent python programmer, i would much rather learn cython from the perspective of the language I'm already good at, rather than learn a whole new language in order to learn cython. 1) PLEASE don't recommend psyco edit: ANY information that will help understand the oficial cython docs is useful information

OpenGL es 2.0 Read depth buffer

- by Brian

Hi! As far as i know, we can't read the Z(depth) value in OpenGL ES 2.0. So I am wondering how we can get the 3D world coordinates from a point on the 2D screen? Actually I have some random thoughts might work. Since we can read the RGBA value by using glReadPixels, how about we duplicate the depth buffer and store it in a color buffer(say ColorforDepth). Of course there need to be some nice convention so that we don't lose any information of the depth buffer. And then when we need a point's world coordinates , we attach this ColorforDepth color buffer to the framebuffer and then render it. So when we use glReadPixels to read the depth information at this frame. However, this will lead to 1 frame flash since the colorbuffer is a weird buffer translated from the depth buffer. I am still wondering if there is some standard way to get the depth in OpenGL es 2.0? Thx in advance!:)

ModalPopup CodeBehind Function Wait For User Response

- by Snave

I have set up a function which returns an enum of the button that the user clicked in the ModalPopup. I have a variable of type enum to store which button the user clicks in the button click event. In this function, I call the ModalPopupExtender's Show() method. My problem is, the function finishes out and returns the default enum (which is "none" since no button was clicked yet) before the ModalPopup can be shown and store which button the user clicks. So without changing the function to a method and using a different way to store the user's button click, how can I pause the function after the Show() method of the MPE has been called and wait for the user to click a button? Edit(11/20/2009): Clarification: On the aspx page, I include a ScriptManager, PlaceHolder, and an asp:Button with a codebehind click event. What I want is to click the button, then in the click event handler, I want to call a custom static class function that returns a variable. One of the arguments it takes is the PlaceHolder. The function creates all the necessary controls in the PlaceHolder needed to display a ModalPopup. It calls the created ModalPopupExtender's Show() method. What should happen: At this point is the ModalPopup gets displayed, the user clicks a button, that button's event handler fires, the button sets a variable indicating that it was clicked, it then calls the ModalPopupExtender's .Hide() method, and then the function returns the variable that indicates which button was clicked. We then return to the event handler from the original button that was clicked and the programmer can then perform some logic based on what variable was returned. Crux: When the ModalPopupExtender's .Show() method gets called, it does not display the ModalPopup until AFTER the function returns a default variable (because no button was clicked yet) and after the event handler from the original button that was clicked ends. What I need: After the ModalPopupExtender's .Show() method is called, I need the ModalPopup to get displayed immediately and I need the function to wait for a button click to be made from the ModalPopup. My thoughts: Some PostBack needs to be made to the page telling it to update and display the ModalPopup Panel. Then maybe a while loop can be run in the function that waits for a button to be clicked in the ModalPopup.

How to get vm arguments from inside of java application?

- by Dmitriy Matveev

Hello, I need to check if some option which can be passed to JVM is explicitly set or is it have default value. To be more specific: I need to create one specific thread with higher native stack size than the default one, but in case then user want to take care of such things by himself by specifying -Xss option I want to create all threads with default stack size (which will be specified by user in -Xss option). I've checked classes like java.lang.System and java.lang.Runtime, but these aren't giving me information about vmargs. Is there any way to get information I need?

Asp.Net MVC does automatic model validation for DateTime but no others

- by MattSlay

I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty. My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields? Sure, I have successfully added the MetadataType(typeof) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?

JasperReports: is it possible to use multiple data sources, or if not, to use collections in paramet

- by Knut Arne Vedaa

It seems that the reporting idiom is that a report consist of a single list of items, with some additional data (parameters). Are there ways to include several unrelated lists in a report, or would this go against the idiom to such an extent that a different tool should rather be used to generate the output? Suppose, for instance, you have a list of Persons that lives in a Building, with names, phone numbers and so on. This list would be the main datasource. Additionally, on the same report you want to show various other information about that Building, such as address, number of floors and so on. The number of items in this information might vary between Buildings, so that you cannot simply put it into static parameters, but would need a map or a list. This is of course a contrieved example, but should serve to illustrate the problem. In short: can you use several unrelated lists in a report?

Difficulty getting Saxon into XQuery mode instead of XSLT

- by Rosarch

I'm having difficulty getting XQuery to work. I downloaded Saxon-HE 9.2. It seems to only want to work with XSLT. When I type: java -jar saxon9he.jar I get back usage information for XSLT. When I use the command syntax for XQuery, it doesn't recognize the parameters (like -q), and gives XSLT usage information. Here are some command line interactions: >java -jar saxon9he.jar No source file name Saxon-HE 9.2.0.6J from Saxonica Usage: see http://www.saxonica.com/documentation/using-xsl/commandline.html Options: -a Use xml-stylesheet PI, not -xsl argument -c:filename Use compiled stylesheet from file -config:filename Use configuration file -cr:classname Use collection URI resolver class -dtd:on|off Validate using DTD -expand:on|off Expand defaults defined in schema/DTD -explain[:filename] Display compiled expression tree -ext:on|off Allow|Disallow external Java functions -im:modename Initial mode -ief:class;class;...
