• How to escape <, >, and & characters to html entities in Oracle PL/SQL

  - by SWilk

  Hi, I need to send HTML emails directly from oracle PL/SQL package. This works almost fine. I have problem with the fact that some of the data fetched from a table contain things like <S>, <L>, and similar fragments, which sometimes ar treated as HTML tags, and even if not, they are always ignored and never displayed. So, I need to escape this column before inserting into email body. Is there a function to escape html special chars into entities automaticly? Or do I need to replace('<','&lt;',string) manually all the special characters? I found a function to escape URLs but not one for HTML :( Best regards, SWilk

• Can Hibernate default a Null String to Empty String

  - by sliver

  In our application we are pulling data from a DB2 mainframe database. If the database has "low values" in a field, hibernate sends a "null" value in the object. This occurs even if the column is defined as "not null". As we are doing XML parsing on this, Castor is having trouble with it. I would like to fix this in Hibernate. Also, all of the hibernate hbm files are generated, so we can't mess with them (they are regened from time to time.) Any way to intercept all Strings and replace nulls with ""?

• pushScene and popScene or replaceScene . which should we use and when ?

  - by srikanth rongali

  I am using push scene to get the next scene. But, I read that for each PushScene the scene is stored in stack. The memory usage is more. So, I am using the replaceScene in place of pushScene. But, with replace scene I am getting the memory-bad-access message in debugger. So, I want to popScene after using it, so that the retain count is zero. But, I am confused in using popScene. If I have a Scene1 and Scene2. I used the following to go in to Scene2. Now I need to remove Scene1 from stack. [[CCDirector sharedDirector] pushScene:Scene2]; Where should I write the popScene to popScene1. How to get the previous scene in current running scene ? Thank you/

• jQuery Sparklines: $.getJSON data can't be read

  - by Bob Jansen

  I'm trying to generate a pie graph with Sparklines but I'm running into some trouble. I can't seem to figure out what I'm doing wrong, but I feel it is a silly mistake. I'm using the following code to generate a sparkline chart in the div #traffic_bos_ss: //Display Visitor Screen Size Stats $.getJSON('models/ucp/traffic/traffic_display_bos.php', { type: 'ss', server: server, api: api, ip: ip, }, function(data) { var values = data.views; //alert(values); $('#traffic_bos_ss').sparkline(values, { type: "pie", height: "100%", tooltipFormat: 'data.screen - {{value}}', }); }); The JSON string fetched: {"screen":"1220x1080, 1620x1080, 1920x1080","views":"[2, 2, 61]"} For some reason Sparklines does not process the variable values. When I alert the variable it outputs "[2, 2, 61]". Now the jQuery code does work when I replace the snippet: var values = data.views; with var values = [2, 2, 61]; What am I doing wrong?

• Modifying association arrays on cloned ActiveRecord objects

  - by Craig Walker

  I have an ActiveRecord model class Foo that has_many Bar. I want to clone a Foo (to get duplicates of most of its attributes) and then modify its Bar instances. This is a problem because cloned ActiveRecord instances share the same associated array; changes to one affect the other. f1 = Foo.new b = Bar.new f1.bars << b f2 = f1.clone f2.bars.includes? b # true f1.bars.clear f2.bars.includes? b # now false The real problem is that I can't detach the bars arrays from either Foo: f1.bars << b f2.bars.includes? b # true f2.bars = [] f2.bars.includes? b # now false f1.bars.includes? b # now also false If I could do that, then I could replace the Bars as I wanted to. However, any change to one Foo seems to affect the other.

• programmatically creating property list from json to include an array

  - by Michael Robinson

  [{"memberid":"18", "useridFK":"30", "loginName":"Johnson", "name":"Frank", "age":"23", "place":"School", },] Someone else posted a similar question but without the fact that it was coming from a JSON deserialization. Quinn had some suggestions but it was confused about where to place/replace the following code (if it's correct): NSDictionary *item1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@" member",[NSNumber numberWithInt:3],nil] forKeys:[NSArray arrayWithObjects:@"Title",@"View",nil]]; into this: NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; if (dict) { rowsArray = [dict objectForKey:@"member"]; [rowsArray retain]; } My Array.plist needs to look like the following: Root: Dictionary V Rows: Array V Item 0: Dictionary Title: String 18 V Children Array V Item 0 Dictionary Title String 30 etc. Thanks in advance. Every tutorial on JSON only shows a simple array being returned, never a 2-D..It's driving me crazy trying to figure this out.

• How to achieve table like rows within container using CSS

  - by Barry

  I'm helping an artist maintain her website and have inherited some pretty outdated code. Have moved lots of redundant common code to include files and am now working on moving from inline styles to more CSS-driven styles. For the gallery pages, e.g. http://artistsatlaketahoe.com/abstract.html, a lot of inline styling is used to force the current layout. My preference would be to replace this entirely with CSS that presents the following table-like layout within the "content" div: [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] I'd like to middle-align the image descriptives & purchase button relative to the image if possible. And then apply some padding above and below each row to stop using tags for vertical spacing. Any ideas how to create a div that I can use to get this kind of layout? Thanks!

• Python: Elegant way to check if at least one regex in list matches a string

  - by houbysoft

  Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

• What are some RCP Deployment Options?

  - by mdamman

  We have an RCP application and we are looking for a better way to do installation/updates. Currently to install, they just unzip a zip file. The zip file also contains scripts in it that are not java code. We were running into some bugs when updating if they don't first delete the old folder that was previous unzipped. The issue with deleting the folder is that the user loses the plugin preferences that were set. The installation would also need to register a COM server. The update would have to update the plugins and also replace the current script folder. What are some of the best options that could be used for installing and updating rcp apps? Thanks!

• Is AMQP suitable as both an intra and inter-machine software bus?

  - by Bwooce

  I'm trying to get my head around AMQP. It looks great for inter-machine (cluster, LAN, WAN) communication between applications but I'm not sure if it is suitable (in architectural, and current implementation terms) for use as a software bus within one machine. Would it be worth pulling out a current high performance message passing framework to replace it with AMQP, or is this falling into the same trap as RPC by blurring the distinction between local and non-local communication? I'm also wary of the performance impacts of using a WAN technology for intra-machine communications, although this may be more of an implementation concern than architecture. War stories would be appreciated.

• How do you write a consistent UI Automation for MS? MSAA & UI Automation don't seem to overlap.

  - by Greg

  Working on a general Automation tool, considering moving from Win32 Message hooks to .net UI Automation, however the feature set of UI Automation doesn't cover all we have in Win32 and still doesn't seem to support all the GUI on Windows. One such example is Windows Live Messenger. Windows Live messenger 2009 is still using the older DirectUIHwnd to draw the gui. This means that you can't use windows messages to send to the controls, because the controls don't have their own HWND. It also seems to defeat the new .net UI Automation framework though the documentation seems to make out as if it can be joined in the UI Automation and Microsoft Active Accessibility document. Looking at MS Accessibility pointed to Active Accessibility 2.0 SDK Tools which showed that MSAA can interact with the contents. Is there some trick to getting the older MSAA technology that UI Automation seems to be trying to replace to actually work with UI Automation? I'd rather not have multiple solutions trying to automate the same windows for windows unlike Windows Live Messenger where each of these techniques is valid and will work.

• Need Magic jQuery Replacement for Selectbox Dropdown Form Element. Thank you!

  - by PlasmaFlux

  Hello! I'm stuck on a problem and, after what seems like days of searching for a solution, I'm reaching out to Stack Overflow for help. I'm trying to replace a standard dropdown form element with a Textbox and a Div containing an unordered list. I'd prefer to have the solution be based on jQuery, but am open to alternatives. I've found a couple jQuery plugins that -almost- do what I need, but are far enough from being a real solution that I need to keep looking. Here's an image of what I'm going for: I'd like the dropdown to look as pictured, and when an element is selected (with mouse or keyboard), have just the first line handed back into the textbox (and not be editable). I'd also like to populate a hidden input field with a value that will be used on Submit. I'm pulling my hair out over this one. Any help and guidance will be most appreciated! Thanks! ~PF

• Show only one validation error-message using replaceWith

  - by timkl

  I am currently working with the jQuery validation plugin, and I want to show only one error-message before the form itself. Right now the validation shows all the error-messages on top of each others as they stack up, as you can see in my live example: http://timkjaerlange.com/foobar/stack-stuff/validate-test.html This is my jQuery: $(document).ready(function() { $("form").validate({ rules: { // bunch of rules here, left out to keep it simple }, messages: { // messages goes here }, errorElement: 'div', errorClass: 'error', errorPlacement: function(error, element) { error.insertBefore('form'); // this is what I've got $('div').replaceWith(error); // trying to replace the prev error } }); }); Anybody know how to this? Is this the best way to show only one error-message? Any help is highly appreciated.

• escaping a dollar in the middle of an ant property

  - by jk

  I have a property whose value contains a $. I'd like to use this property as a regexp in a propertyregexp. Ant appears to resolve the property as a paramater to the propertyregexp, but then the dollar gets interpreted as a regexp symbol. Example: <property name="a" value="abc$" /> <property name="b" value="xyz" /> <path id="paths"> <pathelement location="abc$/def" /> <pathelement location="abc$/ghi" /> </path> <pathconvert property="list" refid="paths" pathsep="${line.separator}" dirsep="/" /> <propertyregex property="list" input="${list}" override="true" regexp="${a}(.*)" replace="${b}\1" /> <echo message="${list}" /> I'd like to the pair xyz/def and xyz/ghi. Is this possible? I'm using Ant 1.8.

  Hi, I have the following code. $(document).ready(function() { $('#btnOpen').click(function(e) { $('#content').modal({ onOpen: function(dialog) { dialog.overlay.fadeIn('slow', function() { dialog.data.hide(); dialog.container.fadeIn('slow', function() { dialog.data.slideDown('slow'); }); }); }, onClose: function(dialog) { dialog.data.fadeOut('slow', function() { dialog.container.slideUp('slow', function() { dialog.overlay.fadeOut('slow', function() { $.modal.close(); // must call this! }); }); }); } }); }); $('#btnClose').click(function(e) { $.modal.close(); }); If I use <a hrf ="#" id="btnOpen">Open</a>, it works perfectly. If I replace the with an ASP.net Button, <asp:Button ID="btnOpen" runat="server" Text="Open" />, nothing happened... Any help please?

• Preventing Netbeans JAXB generation trashing classes

  - by Mac

  I'm developing a SOAP service using JAX-WS and JAXB under Netbeans 6.8, and getting a little frustrated with Netbeans trashing my work every time the XSD schema my JAXB bindings are based upon changes. To elaborate, the IDE automatically generates classes bound to the schema, which can then be (un)marshalled from/to XML using JAXB. To these classes I've added extra methods to (for example) convert to and from separate classes designed to be persisted to database with JPA. The problem is that whenever the schema changes and I rebuild, these classes are regenerated, and all my custom methods are deleted. I can manually replace them by copy-pasting from a backup file, but that is rather time-consuming and tedious. As I'm using an iterative design approach, the schema is changing rather frequently and I'm wasting an awful lot of time whenever it does, simply to reinstate my previous code. While the IDE automatically regenerating the JAXB-bound classes is entirely reasonable and I don't mean to imply otherwise, I was wondering if anyone had any bright ideas as to how to prevent my extra work having to be manually reinstated every time my schema changes?

• Chrome Extension contenteditable get and set caret position

  - by jwize

  I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

• How to lock the Screen customly? Just like WaveSecure in Android

  - by HackNone

  I want to do a demo just like WaveSecure, which win Android Develop Challenge 2 with a third place. Now I have a problem in locking the screen customly, so I want to know how WaveSecure achieve its locking function, as the following picture show: http://goo.gl/XlPP When the mobile is locked, WaveSecure can require customer to input their own password. So I think WaveSecure must replace Android's original locking function. And I also google it, but I didn't find anything helpful. I only find two packages may be helpful. They are: android.app.KeyguardManager android.os.PowerManager But after I reading the Android Docs, I still can't have an idea on it. Can you help me? Thx:)

• Is it valid for RSS feeds to include images with relative paths?

  - by Brian Armstrong

  I have an app which reads lots of RSS feeds. Someone added a feed recently that includes images in the html portion with relative URLS (i.e. it didn't include the http://www.domain.com/ part in front). Is this valid html for an RSS feed? I thought not, but I tried adding the feed to my Google reader and it picked up the images correctly, so they must be doing something smart where they guess the domain based on the feed's url parameter or something. Even if it's not valid, how common is it to see feeds like this in the wild? To display it correctly would require you to parse the html in the feed and find/replace parts of it to insert full URL's, so this seems wrong. But wanted to double check.

• ASP.NET MVC: dealing with Version field.

  - by alex2k8

  I have a versioned model: public class VersionedModel { public Binary Version { get; set; } } Rendered using <%= Html.Hidden("Version") %> it gives: <input id="Version" name="Version" type="hidden" value="&quot;AQID&quot;" /> that looks a bit strange. Any way, when the form submitted, the Version field is always null. public ActionResult VersionedUpdate(VersionedModel data) { ... } How can I pass Version over the wire? EDIT: A naive solution is: public ActionResult VersionedUpdate(VersionedModel data) { data.Version = GetBinaryValue("Version"); } private Binary GetBinaryValue(string name) { return new Binary(Convert.FromBase64String(this.Request[name].Replace("\"", ""))); }

• Single Large v/s Multiple Small MySQL tables for storing Options

  - by Prasad

  Hi there, I'm aware of several question on this forum relating to this. But I'm not talking about splitting tables for the same entity (like user for example) Suppose I have a huge options table that stores list options like Gender, Marital Status, and many more domain specific groups with same structure. I plan to capture in a OPTIONS table. Another simple option is to have the field set as ENUM, but there are disadvantages of that as well. http://www.brandonsavage.net/why-you-should-replace-enum-with-something-else/ OPTIONS Table: option_id <will be referred instead of the name> name value group Query: select .. from options where group = '15' - Since this table is expected to be multi-tenant, the no of rows could grow drastically. - I believe splitting the tables instead of finding by the group would be easier to write & faster to execute. - or perhaps partitioning by the group or tenant? Pl suggest. Thanks

• Changing folder names in Visual Studio when using SVN

  - by Piers Myers

  I am using VS2008/VS2010 with Resharper 5, TortoiseSVN 1.6.8.19260-x64, and AnkhSVN 2.1.8420.8. Most operations I do in Visual Studio are reflected fine in SVN, however, renaming folders in a project can cause problems when I try to submit my changes. Also all the namespaces in the C# source files under the renamed folder need to be updated to reflect the name change. What is the best way to rename the main project folder or any sub folders and ensure there are no issues with SVN? Should it be done outside Visual Studio? What is the best way to update all the namespace changes? Is search/replace the only way? Are there any best practices regarding folder names and their contents?

• Compact Framework - ListView like control ?

  - by no9

  Hello. I have been playing with Compact Framework lately and i need some advice. I have a collection of items. One of the properties on each item is a string type that holds XML. This XML defines image, font, style etc... Im looking for a control (similar to listView) that would replace listBox control. Im not satisfied with listView control, because it is very limited on items level. The control has to be dynamic enough so that my parser could parse the XML and customise the control. For a start i would like to show an image and perhaps some font styles for each row in the control. Here is a sample what im trying to achieve: Any suggestions?
