  • Dynamic case statement in bash

    - by infra.user
    Hi folks, I'm trying to figure out how to create a dynamic case statement in a bash script. For example, let's say I have the output of an awk statement with the following contents red green blue In this scenario, the output can change at any time. I'm trying to then execute different logic if a value is included in this awk output. So if the data above is in $list, then I'd conceptually like to do something like: case "${my_var}" in $list) ..... something_else) ..... esac I'm trying to use this to build a dynamic custom tab completion function (see http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_2 for some background). Any ideas? Thanks.

  • Traditional loop versus Action delegate in C#

    - by emddudley
    After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?

  • struts 2 bean is not created

    - by Dewfy
    Hello colleagues! At first some precondition to my question, I'm using struts2 + tiles2 + toplink. NO spring at all. The simplest scenario - is to display list of entities on the page. To optimize resolving JPA's EntityManager I would like to create helper (JPAResourceBean) that implements lazy load of entity manager. For this purposes I'm going to use struts2's bean declaration: <bean name="myfactory" class="my.model.JPAResourceBean" scope="session" optional="false"/> Why bean is not instantiated neither in session? (I'm using s:property just for debug) ... <s:property value="#session.myfactory" default="buka.1"/> ... nor in plain bean list: ... <s:property value="#myfactory" default="buka.2"/> ... May be the second part of question is - how to resolve this bean from java code?

  • How do I get Eclipse CDT to ignore files

    - by brianegge
    I have a C++ project in Eclipse. The project uses Perforce and Eclipse has the Perforce plugin installed. Everything was fine, until I decided to create a git repo in my project. I created the git repo to snapshot some changes which I wasn't ready to commit. Everything was fine until I refreshed my files in Eclipse. Two problems have occurred: Eclipse found my .git folder, and indexed all of the files inside of it. Eclipse also decided to add all the git file to my pending change list. If I create a new file within Eclipse, I'd like it to add it to Perforce, but if it happens to find a file, I don't want it to do anything with it. I'd also like to give Eclipse a list of file types to always ignore, just like I do with my .hgignore file.

  • documentBuilder: The process cannot access the file because it is being used by another process

    - by st mnmn
    I am using DocumentBuilder (of openXML api), to those who doesn't know the documentBuilder I'll give a short explanation: it has a function 'BuildDocument' which gets list of sources (each source contains wmldocument), and string of fileName to save to. public static void BuildDocument(List<Source> sources, string fileName) the purpose of this function is to build one word docx which contains all the sources. it merges some docs to one. at the end of its functionality it saves the doc using: File.WriteAllBytes(...) but when I run my project on the server I keep getting the error: "The process cannot access the file because it is being used by another process." few times it works ok. and in the visualStudio it also works without errors. what can be the problem?

  • NHibernate Query object collection issue

    - by Mahesh
    Hi, I am new to NHibernate and need some information regarding the internal working of the engine: I have a table called Student and the design is as follows: RollNo Name City Postcode and there are 5 more columns like this. I have School class and mappings associated with it. I am querying RollNo and Name using session as given below: IQuery query = session.CreateQuery("SELECT RollNo,Name FROM Student); Executing query.List resulting in error because the query is returning object[][]. Now, I changed the query as given below: IQuery query = session.CreateQuery("FROM Student); Executing query.List on this query yeilds the desired results. But, the results contain more data than I want. Could you please let me know the query to which I can get RollNo and Name from Student and castable as Student collection. Thanks, Mahesh

  • PHP gallery, thumbnail listing

    - by Benjamin
    Hi everyone, I am planning a dynamic PHP photo gallery and having difficulty deciding on the best way to display the thumbnails after they have been retrieved via MySQL. I considered using an inline unordered list but this resulted in the thumbs being stacked one on top of the other (touching). Also tried a table but not sure how I would start the next row after x number of thumbnails. Any suggestions on page layout for this purpose? I will be using Lightbox to cycle through the photos themselves, that isn't the issue. Also, would a while() loop be best for fetching the list of thumbs and inserting the appropriate HTML? Thanks! -Ben

  • Displaytag export option is not working

    - by Nirmal
    Hello All, I am using Displaytag framework for pagination & exporting purpose. In that i am also using Strut2Tiles Integration. Whenever i am calling any action class it will returning me a list & through Displaytag i am successfully displaying record on my page. For that my jsp page's code looks like : <s:set name="selectedPageSize" value="selectedPageSize" scope="request"/> <s:set value="accountList" scope="request" name="accountList"/> <display:table name="accountList" export="true" class="table" requestURI="" id="accountList" pagesize="${selectedPageSize}" > <display:setProperty name="export.pdf" value="true" /> <display:column property="id" sortable="true" class="sort-title"/> <display:column property="name" sortable="true"/> <display:column property="contactPerson" sortable="true"/> <display:column property="phone1" sortable="true"/> <display:column property="phone2" sortable="true"/> <display:column property="fax" sortable="true"/> <display:column property="email" sortable="true"/> <display:column property="webSite" sortable="true"/> <display:column property="address1" sortable="true"/> <display:column property="address2" sortable="true"/> <display:column property="countryId.name" title="Country" sortable="true"/> <display:column property="stateId.name" title="State" sortable="true"/> <display:column property="countryId.name" title="City" sortable="true"/> <display:column property="isDeleted" sortable="true"/> <display:column title="Delete"> <s:url id="removeUrl" action="finance/deleteAccount.action"> <s:param name="id" value="#attr.accountList.id" /> </s:url> <s:a href="%{removeUrl}" theme="ajax" targets="accountList">Remove</s:a> </display:column> <display:column title="Update"> <s:url id="updateUrl" action="finance/updateAccount.action"> <s:param value="#attr.accountList.id" name="id"/> </s:url> <s:a href="%{updateUrl}&action=update" targets="accountlist">Update</s:a> </display:column> Actually this page is displaying through tiles configuration. Here i have enabled the export option, so it is showing me the exporting options like CSV, EXCEL, XML. But whenver i am clicking on that CSV link, my web browser hanged, means nothing is displayed on it For that exporting solution i have also added filter in my web.xml.

  • Is the Scala 2.8 collections library a case of "the longest suicide note in history" ?

    - by oxbow_lakes
    First note the inflammatory subject title is a quotation made about the manifesto of a UK political party in the early 1980s. This question is subjective but it is a genuine question, I've made it CW and I'd like some opinions on the matter. Despite whatever my wife and coworkers keep telling me, I don't think I'm an idiot: I have a good degree in mathematics from the University of Oxford and I've been programming commercially for almost 12 years and in Scala for about a year (also commercially). I have just started to look at the Scala collections library re-implementation which is coming in the imminent 2.8 release. Those familiar with the library from 2.7 will notice that the library, from a usage perspective, has changed little. For example... > List("Paris", "London").map(_.length) res0: List[Int] List(5, 6) ...would work in either versions. The library is eminently useable: in fact it's fantastic. However, those previously unfamiliar with Scala and poking around to get a feel for the language now have to make sense of method signatures like: def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That For such simple functionality, this is a daunting signature and one which I find myself struggling to understand. Not that I think Scala was ever likely to be the next Java (or /C/C++/C#) - I don't believe its creators were aiming it at that market - but I think it is/was certainly feasible for Scala to become the next Ruby or Python (i.e. to gain a significant commercial user-base) Is this going to put people off coming to Scala? Is this going to give Scala a bad name in the commercial world as an academic plaything that only dedicated PhD students can understand? Are CTOs and heads of software going to get scared off? Was the library re-design a sensible idea? If you're using Scala commercially, are you worried about this? Are you planning to adopt 2.8 immediately or wait to see what happens? Steve Yegge once attacked Scala (mistakenly in my opinion) for what he saw as its overcomplicated type-system. I worry that someone is going to have a field day spreading fud with this API (similarly to how Josh Bloch scared the JCP out of adding closures to Java). Note - I should be clear that, whilst I believe that Josh Bloch was influential in the rejection of the BGGA closures proposal, I don't ascribe this to anything other than his honestly-held beliefs that the proposal represented a mistake.

  • Aborting jQuery().load()

    - by Daniel I-S
    The .load() function of the jQuery library allows you to selectively load elements from another page (subject to certain rules). I would like to know whether it is possible to abort the load process. In our application, a user can browse a list of items. They may choose to click a button which loads and displays additional information about an item from another document (which can take some time). If they choose a different item in the list whilst a .load() is still happening, I would like the loading to be aborted. Is this possible? Is it even worth it? Any ideas? Dan

  • Pre-generating GUIDs for use in python?

    - by rjuiaa1
    I have a python program that needs to generate several guids and hand them back with some other data to a client over the network. It may be hit with a lot of requests in a short time period and I would like the latency to be as low as reasonably possible. Ideally, rather than generating new guids on the fly as the client waits for a response, I would rather be bulk-generating a list of guids in the background that is continually replenished so that I always have pre-generated ones ready to hand out. I am using the uuid module in python on linux. I understand that this is using the uuidd daemon to get uuids. Does uuidd already take care of pre-genreating uuids so that it always has some ready? From the documentation it appears that it does not. Is there some setting in python or with uuidd to get it to do this automatically? Is there a more elegant approach then manually creating a background thread in my program that maintains a list of uuids?

  • Rough/near equivalents of Java and .NET technologies/frameworks

    - by Paul Sasik
    I work in a shop that is a mix of mostly Java and .NET technologists. When discussing new solutions and architectures we often encounter impedance in trying to compare the various technologies, frameworks, APIs etc. in use between the two camps. It seems that each camp knows little about the other and we end up comparing apples to oranges and forgetting about the bushels. While researching the topic I found this: Java -- .Net rough equivalents It's a nice list but it's not quite exhaustive and is missing the key .NET 3.0 technologies and a few other tidbits. To complete that list: what are the near/rough equivalents (or a combination of technologies) in Java to the following in .NET? WCF WPF Silverlight WF Generics Lambda expressions Linq (not Linq-to-SQL) ...have i missed anything else? Note that I omitted technologies that are already covered in the linked article. I would also like to hear feedback on whether the linked article is accurate. Thanks. (Will CW if requested.)

  • DOS Batch script loop

    - by Tom J Nowell
    I need to execute a command 100-200 times, so far my research indicates that I would either have to copy paste 100 copies of this command, OR use a FOR loop, but the for loop expects a list of items, hence I would need 200 files to operate on, or a list of 200 items, hence defeating the point. I would really not have to write a C program and go through the length of documenting why I had to write another program to execute my program for test purposes. Modification of my program itself is also no an option. So, given a command how would I execute it times via a DOS batch script?

  • jQuery pre document ready event

    - by Luke Duddridge
    Hi, I have a list of 179 thumbnail images that I am trying to apply a jQuery lightbox tool to an unorder list of hyper-links. The problem I have is, the jQuery isnt firing until the images have finished downloading, each image is around 23K so on their own, not so big, but as a group this equates to around 4MB. There is a delay on IE (main browser used by clients) of a good 5 seconds before the page has completely downloaded every thumbnail and then allows the jQuery to fire. I have tried putting the jQuery document ready event in various places with no success, and only been able to put a bandaid on by setting the css on the ul to hide using display:none before applying .show() after the lightbox has applied. I was hoping there is a way to make the jQuery scripts fire before all the content has downloaded? Cheers

  • Setup Project is not correctly registering assembly in GAC

    - by Arnold Zokas
    I have created a custom Rewrite Provider for IIS 7 following instructions in this article: Developing a Custom Rewrite Provider for URL Rewrite Module To simplify deployment, I have created a VS2010 Setup Project and configured it to deploy my assembly to GAC. When I run the installer, it completes successfully, and appears to be registered the assembly in GAC (I have verified using gacutil.exe /l). However, when I go to IIS Manager to register the new rewrite provider it is not displayed in the list of available providers. I have also tried to install the assembly manually using gacutil.exe /if. This does work and makes assembly visible in the list of available providers in IIS Manager. Am I missing some sort of configuration in my Setup Project?

  • 301 Redirects, and the correct regex to go with it

    - by Tisch
    Hi Guys, I have several URLs that I want to redirect to the same place, however these are dynamic URLs. The structure is something like this: http://www.mysite.com/declaration/list?[query_string] What I think would be ideal for this situation is to use some regex in my .htaccess file to redirect all these links to the sites home page. I was wondering if someone could help me with the regex for this situation. So far, I have this, but it doesn't work: RewriteCond %{QUERY_STRING} ^(.*)$ RewriteRule ^/declaration/list$ http://www.mysite.com/$ [R=301,L] My regex is weak to say the least, something I want to, and am trying to learn. Thanks in advance. Tom

  • DataGrid giving error and getting invisible whenever some elements visibility is changed

    I have a datagrid in which i have textblocks as one column.Then in the next column i have progress bar over which there is a textblock.On loading row of datagrid,i add these three into lists of textblock and progressbar.I start the first progress bar and after 15-20 minutes next progress bar is started.The next progress bar is getting started fine and after 20 minutes it is getting invisible.The problem is that if i try to make textblock invisible,then the whole Datagrid gets invisible and stops working.After all the tasks in the Datagrid are complete i need to make DataGrid invisible and also when i try to do so,the grid becomes invisible and no other event gets fired.... e.g List txtlist=new List(); i=1; txtlist[i].Visibility=Visibility.Collapsed;

  • Subversion roadmap

    - by gbjbaanb
    Recently there was a post to the subversion dev mailing list suggesting a vision and roadmap for the future of Subversion. As a result, I'm posting this to elicit some suggestions and contributions from the users of Subversion. Any comments are welcome, and I shall feedback a synopsis with a link to this question to the dev mailing list. On the post, several ideas were suggested as being "very nice to have" and are offered as the starting point of a future roadmap. These are: Obliterate Shelve/Checkpoint Repository-dictated Configuration Rename Tracking Improved Merging Improved Tree Conflict Handling Enterprise Authentication Mechanisms Forward History Searching Log Message Templates So given all the above, what features in subversion, or missing from subversion, do you think could be improved or added?

  • .net dictionary and lookup add / update
