• Flex 3 give DataGrid Data to function

  - by codeworxx

  Hey Guys, i have a Problem to send a value from the DataGrid to a function- this is my function: private function browseLoc( location:String ):void { Alert.show(location,'Information'); } Now i have my DataGrid which receives Information from an XML File. Everything works fine. All Information is shown correctly with that Tags: <mx:Image x="10" y="346" width="157" height="107" scaleContent="true" source="{codeworxx.pages.page[selectedPageIndex].preview}"/> <mx:Label x="10" y="492" width="157" fontWeight="bold" text="{codeworxx.pages.page[selectedPageIndex].visible}"/> <mx:Text x="10" y="513" width="157" text="{codeworxx.pages.page[selectedPageIndex].description}"/> <mx:Button x="10" y="461" label="Visit Website" width="159" click="browseLoc('{codeworxx.pages.page[selectedPageIndex].url}')"/> except the Button. The Function "browseLoc" only has the text {codeworxx.pages.page[selectedPageIndex].url} in it - not the value. How do i do it? Hope you can help! Thanks, Sascha

• Should one use PHP to print all of a page's HTML?

  - by Mala

  Hi So I've always developed PHP pages like this: <?php goes at the top, ?> goes at the bottom, and all the HTML gets either print()ed or echo()ed out. Is that slower than having non-dynamic html outputted outside of <?php ?> tags? I can't seem to find any info about this. Thanks! --Mala UPDATE: the consesus seems to be on doing it my old way being hard to read. This is not the case if you break your strings up line by line as in: print("\n". "first line goes here\n". "second line goes here\n". "third line"); etc. It actually makes it a lot easier to read than having html outside of php structures, as this way everything is properly indented. That being said, it involves a lot of string concatenation.

• Check for a unique value within a count, but get all results

  - by pedalpete

  I'm trying to create a single query which, similar to stack overflow, will give me the number of votes, but also make sure that the currently viewing user can't upvote again if they've already upvoted. my query currently looks like SELECT cid, text, COUNT(votes.parentid) FROM comments LEFT JOIN votes ON comments.cid=votes.parentid AND votes.type=3 WHERE comments.type=0 AND comments.parentid='$commentParentid' GROUP BY comments.cid But I'm completely stumpted on how to add the check to see if the userid is in the votes table. The other option is to add a seperate query where SELECT COUNT(*) FROM votes WHERE userid='$userid' AND parentid='$commentParentid' AND type=3 I'm just realizing I'm so lost with this that I don't even really know what tags to provide.

• etree.findall: 'OR'-lookup?

  - by piquadrat

  I want to find all stylesheet definitions in a XHTML file with lxml.etree.findall. This could be as simple as elems = tree.findall('link[@rel="stylesheet"]') + tree.findall('style') But the problem with CSS style definitions is that the order matters, e.g. <link rel="stylesheet" type="text/css" href="/media/css/first.css" /> <style>body:{font-size: 10px;}</style> <link rel="stylesheet" type="text/css" href="/media/css/second.css" /> if the contents of the style tag is applied after the rules in the two link tags, the result may be completely different from the one where the rules are applied in order of definition. So, how would I do a lookup that inlcudes both link[@rel="stylesheet"] and style?

• 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

• Query multiple custom taxonomy terms in Wordpress 2.8?

  - by thechrisvoth

  I created a custom taxonomy named 'technologies' but cannot query multiple terms like I can with categories or tags. These querys DO work: query_posts('tag=goldfish,airplanes'); query_posts('technologies=php'); However, neither of the following work correctly: query_posts('technologies=php,sql'); query_posts('technologies=php&technologies=sql'); My objective: Show all posts with a technology of 'php' and all posts with a technology of 'sql' Any ideas? Is this even possible? Thanks!

• Best library to parse HTML with Python 3 and example?

  - by TMC

  I'm new to Python completely and am using Python 3.1 on Windows (pywin). I need to parse some HTML, to essentially extra values between specific HTML tags and am confused at my array of options, and everything I find is suited for Python 2.x. I've read raves about Beautiful Soup, HTML5Lib and lxml, but I cannot figure out how to install any of these on Windows. Questions: What HTML parser do you recommend? How do I install it? Do you have a simple example on how to use the recommended library to snag HTML from a specific URL and return the value out of say something like this: fooLink (say we want to return "/blahblah")

• how to check whether some entered InnerText is present in an XML or not and to give an exception?

  - by Damodar

  Hey all, I have written a code in C# - XML which checks whether a value is there or not in a given XML document and prints the value and the particular tag associated with the value. When we enter the Value of the Inner Text it will look for the value in the document and find it. I dont understand what exception to catch when the entered value is not there in the document. I tried doing like this but it is not working. 1. if (inpXMLString != AppChildNode.InnerText) throw new InvalidDataException("The entered value" + " " + inpXMLString + " " + "doesnot exist"); Here : inpXMLstring = entered value; AppChildNode.InnerText = value of the tags searched. 2. catch (System.Xml.XmlException e1) { Console.WriteLine(e1.Message); } this does not give any exception when the entered value is not there in the XML document. Please help me in this regard.

• HTML5 offline video caching in mobile safari

  - by jj

  Sorry if this gets posted twice, but Safari crashed while posting the first version, and I don't see it in my profile. Anyway I can't seem to get Safari on the iPhone or iPad to offline cache videos. Everything else gets cached just fine when I go offline. The video file is obviously in the manifest, but I just get the broken arrow. Works fine in Safari desktop. Any clues? I've tried both object embed and the video tags.

• How to send argument securely using Process class?

  - by Sebastian

  Hello, I'm using System.Diagnostics.Process to execute an svn command from a windows console application. This is the configuration of the process: svn.StartInfo.FileName = svnPath; svn.StartInfo.Arguments = string.Format("copy {0}/trunk/ {0}/tags/{1} -r head -q --username {3} --password {4} -m \"{2}\"", basePathToRepo, tagName, message, svnUserName, svnPassword); svn.StartInfo.UseShellExecute = false; svn.Start(); svn.WaitForExit(); My problem is that those arguments, which include the svn credentials, are sent (I suppose) in an unsecure way. Is there a way to send these arguments in a secure way using the Process class? Thanks!

• How to perform COUNT() or COUNT(*)

  - by ninumedia

  I have a list of tags in a database. Ex: villan hero spiderman superman superman I wanted to obtain a sorted list of the tag names in ascending order and the number of times the unique tag appeared in the database. I wrote this code: Ex: SELECT hashtag.tag_name, COUNT( * ) AS number FROM hashtag GROUP BY hashtag.tag_name ORDER BY hashtag.tag_name ASC This yields the correct result: hero - 1 spiderman - 1 superman - 2 villan - 1 How can I obtain the full COUNT of this entire list. The answer should be 4 in this case because there are naturally 4 rows. I can't seem to get a correct COUNT() without the statement failing. Thanks so much for the help! :)

• 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!

• Regular Expression find a phrase not inside an HTML tag

  - by James Buckingham

  Hi there, I'm struggling a bit with this regular expression and wondered if anyone was about to help me please? What I need to do is isolate the 1st phrase inside a string which is NOT inside an HTML tag. So the examples I have at the moment are: This is some test text about ITS for the ITS department. Also worth mentioning ABS as well I guess.ITS, ... and ... This is some ITS test text about ITS for the ITS department. Also worth mentioning ABS as well I guess So in the first example I want it to ignore the wrapped ITS and give me the ITS at the end of the 1st sentence. In the second example I want it to return the ITS at the start of the 2nd sentence. The aim is to replace these with my own custom wrapped acronym tags in a ColdFusion application I'm writing. Thanks a lot, James

• jQuery Validation Plugin + equalTo Not Working

  - by Tom Winchester

  Hey guys, Here is what I am currently using to attempt to validate a form. When I press submit with no values entered into the form, I get the error messages for each of the inputs as expected. However, no matter what I put in newpassword2 or newemail2 they never 'pass' validation. I've tried everything from copy and paste to making them one letter each to no success. Perhaps I am not using the equalTo attribute correctly... I've also verified that all the names of the selectors agree with the input id's on the form. Also, all of the inputs are contained within the form, so there aren't any outside of the form tags (I read that was an issue with someone else). $(document).ready(function() { $("#account_data").validate({ rules: { newpassword1: { required: true }, newpassword2: { equalTo: "#newpassword1" }, newemail1: { required: true, email: true }, newemail2: { equalTo: "#newemail1" } } }); }); Any help would be extremely appreciated! THANK YOU!!! -Tom-

• IE6 image scaling with bicubic filter

  - by thehuby

  I have a project where I have to resize some images in the actual browser side. IE8, FF3 et al all apply a filter to smooth the resizing of the image, so in these browsers everything looks good. In IE7 I have applied the following fix which works great: -ms-interpolation-mode:bicubic; In IE6 however I can only find references to the AlphaImage Filter (the same one used to enable alpha transparency on PNG files). However I can't find an example of how to use it, nor have I been able to get it working myself. Can anyone provide me with an example? Preferably applied to actual img tags, though I could use background images if required. MSDN link (for what its worth): http://msdn.microsoft.com/en-us/library/ms532969%28VS.85%29.aspx The code I am using in my CSS is applied to the img, though I've tried applying it to the img container as well (with no effect): #provider-list li img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="/image.gif", sizingMethod="scale"); } A thousand thank you's in advance :) Rick

• Construct a LPCWSTR on WinCE in C++ (Zune/ZDK)

  - by James Cadd

  What's a good way to construct an LPCWSTR on WinCE 6? I'd like to find something similar to String.Format() in C#. My attempt is: OSVERSIONINFO vi; memset (&vi, 0, sizeof vi); vi.dwOSVersionInfoSize = sizeof vi; GetVersionEx (&vi); char buffer[50]; int n = sprintf(buffer, "The OS version is: %d.%d", vi.dwMajorVersion, vi.dwMinorVersion); ZDKSystem_ShowMessageBox(buffer, MESSAGEBOX_TYPE_OK); That ZDKSystem_ShowMessageBox refers to the ZDK for hacked Zunes available at: http://zunedevwiki.org This line of code works well with the message box call: ZDKSystem_ShowMessageBox(L"Hello Zune", MESSAGEBOX_TYPE_OK); My basic goal is to look at the exact version of WinCE running on a Zune HD to see which features are available (i.e. is it R2 or earlier?). Also I haven't seen any tags for the ZDK so please edit if something is more fitting!

• Why is nodeName sometimes all-caps in javascript DOM?

  - by harpo

  So I have a DOM document that looks essentially like this <categories> <category id="1"/> <category id="2"/> </categories> This is how the document previews in Firebug, as I would expect. However, when I POST this to the server, I get <categories> <CATEGORY id="1"/> <CATEGORY id="2"/> </categories> Indeed, doc.documentElement.firstChild.nodeName returns "CATEGORY". The nodes are added using jQuery.append('<category/>'). Why are the child tags returned in all caps?

• How to store private pictures and videos in Ruby on Rails

  - by TK

  Here's a story: User A should be able to upload an image. User A should be able to set a privacy. ("Public" or "Private"). User B should not be able to access "Private" images of User A. I'm planning to user Paperclip for dealing with uploads. If I store the images under "RAILS_ROOT/public/images", anyone who could guess the name of the files might access the files. (e.g., accessing http://example.com/public/images/uploads/john/family.png ) I need to show the images using img tags, so I cannot place a file except public. How can I ensure that images of a user or group is not accessible by others?

• Mysql Select 1:n

  - by clinisbut

  Hello, I have two tables that relates 1:n content --------- - id - title - text content_meta ------------- - id - content_id - meta_key - meta_value A content can have multiple content_meta registers associated to it. Typically content_meta will contain the category, tags, descriptions and all that stuff, so I really don't know the number of registers a content will have. What I want to accomplish is to take the content register and also all the related registers in content_meta in a single query. I've tried the subselect approachment but seems that I can only get one register/column (¿?) SELECT content.*, ( SELECT * FROM content_meta WHERE content_id = content.id ) FROM content This query complains that "Operand should contain 1 column(s)", so changing the '*' by for example meta_key clears the error, but returns a NULL for this subselect... SELECT content.*, ( SELECT meta_key FROM content_meta WHERE content_id = content.id ) FROM content Can anybody show me where to go from here please?
