• Microsoft Excel 2013

  - by Dan LaMoreaux

  We use a spreadsheet as our timecards. The template is stores on the server with links to it on the individual Desktops. I am trying to figgure out the VB so that wnen the cell for username (B5) is blank, the VB will place next sundays date in (B7). After the user enters thier name in B5, I need it to not change B7 again. If I use a formula in B7 "=IF(B5="",TODAY()+8-WEEKDAY(TODAY()),B7)" i need to enable the curcular calcualtions, which don't follow from the template to the spreadsheet, thus causing errors for every individual. Corporate says that they need to be in Excel, because of the import software. Otherwise I'd use Word and the "CreateDate" function. I've been trying to learn the VB to do it, but I was hoping that soem expert could whip out the code in 5 min. flat and just let me disect it.

• Unexpected behavior in Bash

  - by cYrus

  From man bash: A simple command is a sequence of optional variable assignments followed by blank-separated words and redirections, and terminated by a control operator. The first word specifies the command to be executed, and is passed as argument zero. The remaining words are passed as arguments to the invoked command. So it's perfectly legal to write: foo=bar echo $foo but it doesn't work as I expect (it prints just a newline). It's quite strange to me since: $ foo=bar printenv foo=bar TERM=rxvt-unicode [...] Could someone please explain me where I'm doing wrong?

• Almost 2013 - Any decent options for mp3 to text? (Speech Recognition)

  - by ajacian81

  I know there's some questions here on s/u regarding converting spoken word mp3 to text, however, most are pretty old (2010 and earlier). I'm just wondering if there's any new legitimate options for this task - if google has shown us anything, speech recognition has come a long way. Personally, I'd prefer a linux based solution, but I'm not picky. I've heard a lot about something called Sphinx, but I tried to set it up and get it going but I couldn't. I know there's a number of different componenents for Sphinx so maybe I was doing it wrong? Either way, are there any new applications for Speech recognition, especially from MP3 files? Thanks!

• Coding guidelines + Best Practises?

  - by Chathuranga Chandrasekara

  I couldn't find any question that directly applies to my query so I am posting this as a new question. If there is any existing discussion that may help me, please point it out and close the question. Question: I am going to do a presentation on C# coding guidelines but it is not supposed to limit to coding standards. So I have a rough idea but I think I need to address good programing practices. So the contents will be something like this. Basic coding standards - Casing, Formatting etc. Good practices - Usage of Hashset over other data structures, String vs String Builder, String's immutability and using them effectively etc Really I would like to add more good practices (Especially to improve the performance.) So like to hear some more good practices to be used with C#. Any suggestions??? (No need of large descriptions :) Just the idea is sufficient.)

• VS2010 method comment block pretty format.

  - by camelCase

  I have just installed the lastest RC of VS2010, which for me represents a shift from VS2008. A new comment formatting feature that I was looking forward to appears to be missing. About 6 months ago I read a Scott Gu blog post that mentioned a new VS2010 feature that would format /// style method comment blocks into more readable formatted regions inline with other code. The Scott Gu blog did not provide a screen shot but I was expecting the VS2010 editor to remove the XML tags from the /// method comment block and render just the essential text comment. Was this feature pulled during the Beta, or is there an option switch urking somewhere?

• How can I retain carriage returns when I'm encrypting data?

  - by William Calleja

  I have this following setup, a textarea named with some data in it that may have carriage returns and another textarea that has style='display:none' in order to make it hidden as follows: <textarea id="myTextarea" onBlur="encryptMyData()"></textarea> <textarea name="encryptedText" style='display:none'></textarea> the user enters data in the first textarea and when that text area loses focus the 'encryptMyData()' javascript function is calling an ajax call to take whatever the user entered in the first textfield, encrypt it using rijndael, and paste it in the encryptedText textarea so that it is stored in the database later. Now what I need to do is this, find a way to convert the carriage returns before encryption to a tag like so [cr] so that when I retrieve the data, all formatting is retained. Any idea how I do this? I'm using asp.net and c# to perform the encryption.

• When should I use String.Format or String.Concat instead of the concatenation operator?

  - by Kramii

  In C# it is possible to concatenate strings in several different ways: Using the concatenation operator: var newString = "The answer is '" + value + "'."; Using String.Format: var newString = String.Format("The answer is '{0}'.", value); Using String.Concat: var newString = String.Concat("The answer is '", value, "'."); What are the advantages / disadvantages of each of these methods? When should I prefer one over the others? The question arises because of a debate between developers. One never uses String.Format for concatenation - he argues that this is for formatting strings, not for concatenation, and that is is always unreadable because the items in the string are expressed in the wrong order. The other frequently uses String.Format for concatenation, because he thinks it makes the code easier to read, especially where there are several sets of quotes involved. Both these developers also use the concatenation operator and String.Builder, too.

  - by Alex_Bender

  I'm trying to write bash command wrapper, which will be patch bash current command on the fly. But i'm faced with the problem. As i'm not a good Shell user, i can't write right expression of variable assignment in string. See bellow: I'm set trap to preexecute, through this: alex@bender:~$ trap "caller >/dev/null || xxx \"\${BASH_COMMAND}"\" DEBUG; I want change variable BASH_COMMAND, do something like BASH_COMMAND=xxx ${BASH_COMMAND} but i don't know, how i need escaping variables in this string NOTE: xxx -- my custom function, which must return some value, if in end of command situated word teststr function xxx(){ # find by grep, if teststr in the end `echo "$1" | grep "teststr$" >/dev/null`; # if true ==> do if [ "$?" == "0" ]; then # cut last 6 chars (len('teststr')==6) var=`echo "$1" | sed 's/......$//'`; echo "$var"; fi } How can i do this stuff?: alex@bender:~$ trap "caller >/dev/null || ${BASH_COMMAND}=`xxx $BASH_COMMAND`" DEBUG;

• How can I convert convert docx or wordml xml files to xsl-fo?

  - by Jon Pastore

  I've been looking for a method to convert docx or wordml xml to xsl-fo. I read this post: http://stackoverflow.com/questions/156683/what-is-the-best-xslt-engine-for-perl but I'm having exceptional problems getting apache-fop going. I was able to download the bins and run it locally but the formatting was a little off and it didn't maintain the headers and footers or section 1 or section 3 (17 page doc 3 sections) it also overlapped the text over the outline numbers and did not maintain the font used. trying a more simple test caused fop to fail completely. I would like to find a way to create a PDF that is at least close to 100% accurate reproduction of the original doc.

• Simple PHP Regex question

  - by Dave Kiss

  Hi all, I'd like to validate a field in a form to make sure it contains the proper formatting for a URL linking to a Vimeo video. Below is what I have in Javascript, but I need to convert this over to PHP (not my forte) Basically, I need to check the field and if it is incorrectly formatted, I need to store an error message as a variable.. if it is correct, i store the variable empty. // Parse the URL var PreviewID = jQuery("#customfields-tf-1-tf").val().match(/http:\/\/(www.vimeo|vimeo)\.com(\/|\/clip:)(\d+)(.*?)/); if ( !PreviewID ) { jQuery("#cleaner").html('<div id="vvqvideopreview"><?php echo $this->js_escape( __("Unable to parse preview URL. Please make sure it's the <strong>full</strong> URL and a valid one at that.", 'vipers-video-quicktags') ); ?></div>'); return; } The traditional vimeo url looks like this: http://www.vimeo.com/10793773 Thanks!

• Zend framework currency validation

  - by Dan

  How can I validate (a form element in this case) to ensure that the value is a currency? Have looked at Zend_Validate_Float. Needs to check that value is between 0 and 2dp. Ideally locale-aware (as ZVF is) to allow for locale specific formatting (thousands, decimal as comma/dot) Would also want to extend to allow/disallow negative values And provide optional upper/lower limits. Is the key, as I can do 3. and 4. with a chain. Do I need regex?

• database security with php page that spits out XML

  - by Rees

  Hello, I just created a PHP page that spits outs some data from my database in an XML format. This data is fetched from a flex application I made. I had spent a long time formatting my tables and database information and do not want anyone to be able to simply type www.mysite.com/page_that_spits_out_XML.php and steal my data. However, at the same time I need to be able to access this page from my flex application. Is there a way I can prevent other people from doing this? Thank you!

• Extract paragraphs from Wikipedia API using PHP cURL

  - by Kane

  Here's what I'm trying to do using the Wikipedia (MediaWiki) API - http://en.wikipedia.org/w/api.php Do a GET on http://en.wikipedia.org/w/api.php?format=xml&action=opensearch&search=[keyword] to retrieve a list of suggested pages for the keyword Loop through each suggested page using a GET on http://en.wikipedia.org/w/api.php?format=json&action=query&export&titles=[page title] Extract any paragraphs found on the page into an array Do something with the array I'm stuck on #3. I can see a bunch of JSON data that includes "\n\n" between paragraphs, but for some reason the PHP explode() function doesn't work. Essentially I just want to grab the "meat" of each Wikipedia page (not titles or any formatting, just the content) and break it by paragraph into an array. Any ideas? Thanks!

• How to select items from XmlList

  - by Cen

  My Flash designer is reading an XML stream I'm sending back to the browser (I'm a C# dev). We have this working fine. He is then selecting into an XMLList where a element has its id a certain value i.e. . This is also working just fine. In this XmlList, are Events, that look a little something like this: event startdate enddate end event I don't know how to use the formatting here - but each of those items is an element. startdate would have a value such as 04/02/2010 and enddate 6/30/2010. Now, from this XmlList I do have of Events, I need to select all Events where a new variable myDate, falls in between the startdate and enddate. I'm not sure how to do this in AS3 - can anyone help me? Thank you very much in advance!

• Why does Komodo edit not open files on doubleclick due to some path encoding error?

  - by gakera

  When I double click a file in finder to open in Komodo edit, it displays an error message saying it can't find the file and the path is displayed, but with wrong encoding, such that special characters such as "ó" and "ð" are displayed as some weird boxes. Screenshot: http://i51.tinypic.com/2qkleg4.jpg I'm running OSX Snow Leopard 10.6.4 and Komodo Edit version 5: "Komodo Edit, version 5.2.4, build 4343, platform macosx-x86. Built on Tue Dec 8 18:18:35 2009." When I drag the file into Komodo edit it opens just fine displaying the path correctly with "ó"s and all :P This doesn't happen if I right click the file in finder and select to open it with TextEdit or Word or (God forbid) MacVim - only when I select to open it in Komodo edit. This is annoying as all hell.

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• Does Ubuntu 12.04.1 come with everything I need for using virtual servers and are the tools efficient?

  - by orokusaki

  I noticed that Ubuntu 12.04.1 comes with Xen, OpenStack, KVM and other virtualization-related tools. I have used VMWare in the past. If I was to use Xen for visualization, would I see considerable performance lost, since Xen is run on the host OS? Is it even run on the host OS, or is it like VMWare where it's installed below any Linux OS on the machine (embedded, I guess is the word)? Do you have any recommendations on what sort of set up to use with these built-in tools? I have 2 physical servers, side-by-side. Each will need a VM used for Postgres and a VM used as an app server. One will be a failover for the other.

• Is using value converters to generate GUI-friendly strings a misuse of value converters?

  - by tempy

  Currently, I use value converters to generate user-friendly strings for the GUI. As an example, I have a window that displays the number of available entities in the status bar. The Viewmodel simply has an int dependency property that the calling code can set, and then on the binding for the textbox that displays the number of entities, I specify the int dependency property and a value converter that changes "x" into "x entities available". My code is starting to become littered with these converters, and I have a large number of annoying resource declarations in my XAML, and yet I like them because all the GUI-specific string formatting is being isolated in the converters and the calling code doesn't have to worry about it. But still, I wonder if this is not the purpose that value converters were made for.

• Using search and replace to remove line breaks in Open Office

  - by chrisfs

  Hi, I've imported a document into Open Office and it has a number of hard returns in wrong places. In MS Word, I could use the search and replace to simply get rid of them all easily, but Open Office's earch won't find them. I tried /n with the 'use regular expressions' box checked, but it seems that only looks for 'shift-enter' breaks and not ordinary hard returns. Is there another way to remove them all quickly, or do I have to go manually through the document and remove each one individually. This is a surprising oversight for Open Office.

• How do I override Currency symbols in Java?

  - by edgydruid

  I'm trying to print prices in Turkish Liras (ISO 4217 currency code TRY) with Java. When I do Currency curr = Currency.getInstance("TRY"); Locale trLocale = new Locale("tr", "TR"); System.out.println(curr.getSymbol(trLocale)); the output is: "YTL". However, the currency symbol for Turkish Lira has recently changed from "YTL" to "TL" (as can be seen on the Wikipedia page for Turkish Lira). Formatting with NumberFormat gives a similar result. I really don't want to write yet another Currency class, especially when Java has one built-in. Is there a way to override Java's default currency symbol for TRY to "TL"?

• Cannot select fields with the mouse Windows 7

  - by Nick

  Lately I cannot select a word (field) with the mouse. When I left click on a field drag the mouse to the end of the field then release the button, the selection (blue shading) disappears. Sometimes after several tries the shading stays and I can delete the field. Up to a week ago everything worked fine. Is this a bug, virus? I am using Windows 7 Also, in Live Mail after I finished reading an item in the Inbox, I click the X in the upper right corner to return to the rest of my mail, but instead it takes me back to the desktop and have to double click the Live Mail again to continue. Again this only happened recently. Things worked OK before and this does not happen regularly.

• Windows detected a hard disk failure* - what should I do?

  - by bart

  I'm using Windows 7 x64 Ultimate, I'm getting windows error popups like this one for about 3 days, multiple times a day: This Samsung SpinPoint F3 HD502HJ 500 GB is about 2 years old and I already checked it with Samsung ES Tool 3.0, did all the scans (took hours) and everything is fine! I have no malware, viruses and this started to happen after I have had some electrcity issues at my house (multiple power surges / overvolatege during the night, PC was connected, but turned off), any ideas? What other test should I perform? I believe the disk could be damaged, but then diagnostic tools should prove this, right? *in fact "Windows detected hard disk problem" but I was unable to put word "problem" within the title as well.

• Can I disallow printing with parent controls on Snow Leopard?

  - by Quinn Taylor

  I have two children under 4 who are quite computer-savvy, and have their own account managed by parental controls to restrict what they can do an see. However, I haven't found a way to disallow them from printing, and I'm looking for a way do so. Their pictures of Sesame Street and Word World are cute and all, but I'd like to be in control of what (or even if) they print. (Our printer is connected wirelessly, not directly to the Mac.) I know I can add more time or authorize use of a given application by providing my password — can I do something similar for printing, such as approving or denying particular print jobs?

• Using Yii framework, what would be a right way to process an attribute before displaying it using CH

  - by Karolis

  Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)
