  • if (condition) continue; OR if (!condition) { ... }? (style preference)

    - by Hosam Aly
    I know this is a matter of style, hence the subjective tag. I have a small piece of code, with two nested conditions. I could code it in two ways, and I'd like to see how more experienced developers think it should look like. Style 1: while (!String.IsNullOrEmpty(msg = reader.readMsg())) { RaiseMessageReceived(); if (parseMsg) { ParsedMsg parsedMsg = parser.parseMsg(msg); RaiseMessageParsed(); if (processMsg) { process(parsedMsg); RaiseMessageProcessed(); } } } Style 2: while (!String.IsNullOrEmpty(msg = reader.readMsg())) { RaiseMessageReceived(); if (!parseMsg) continue; ParsedMsg parsedMsg = parser.parseMsg(msg); RaiseMessageParsed(); if (!processMsg) continue; process(parsedMsg); RaiseMessageProcessed(); } (Side question: how do I put empty lines in the source code sample?)

  • How to make an NSOutlineView indent multiple columns?

    - by Rinzwind
    What would be the easiest or recommended way for making an NSOutlineView indent multiple columns? By default, it only indents the outline column; and as far as I know there is no built-in support for making it indent other columns. I have an NSOutlineView which shows a comparison between two sets of hierarchical data. For visual appeal, if some item in the outline column is indented, I'd like to indent the item on the same row in another column by the same indentation amount. (There's also a third column which shows the result of comparing the two items, this column should never be indented.) Can this only be achieved by subclassing NSOutlineView? And what would need to be overridden in the subclass? Or is there an easier way to get it to indent multiple columns?

  • Wordpress Digg-Like Voting System Plugin

    - by mikemick
    I just found out about BuddyPress (a collection of plugins that convert a WordPress MU install into a social network) and now I was wondering if there are any Digg-like voting plugins for WordPress. This would eventually integrate into a BuddyPress website, where the site members would submit, vote and comment on stories (much like Digg). I have a feeling I will end up having to build this from scratch, but since the site will be built on WordPress, I was wondering if there were any plugins already available that add this functionality. So far I have come up empty in my search. I did find a Wordpress blog that had this functionality WpVote. It even creates thumbnails of the story webpage automatically (I'm assuming) using websnapr. I browsed through the page source and didn't seem to find any hints of a WP plugin that they are using.

  • How to create a vector of lists in R?

    - by Martin
    Hi, I have a list (tmpList), which looks like this: $op [1] "empty" $termset $termset$field [1] "entry" $termset[[2]] $termset[[2]]$explode [1] "Y" This is a list with a list inside. If I add this list to a vector theOneVector = c(theOneVector, tmpList) Now the resulting vector is of the length 2, because the first entry ("op") of the list is separated from the tmpList. Is it possible to append the complete tmpList into this vector? I already tried it with theOneVector = c(theOneVector, list(tmpList)) which gives a vector with the length of 1, but it is very cumbersome to access the elements of the list with this extra list around the list. (Too much list in one sentence I think.) Any help would be appreciated, Martin

  • A trigger on hibernate (maybe this is called interceptor)

    - by Ittai
    Hi, I have a module which uses Hibernate as an ORM solution with EHCache as second level cache. I have another seperate module which inserts and updates the database. What I need is to have the ability to trigger an event when a row is inserted or updated. Let's say I have a Customers table and it is mapped to a Customer entity. I want some procedure to notify me that a new Customer has been added. Regarding the second seperate module it uses Hibernate also but at least for the time being they are not connected (I'm pointing this out as if someone thinks that I must share the Hibernate session (or something of the sort) between them then this is something I will consider). Please note that I have limited experience with Hibernate. Thanks in advance

  • Passing more than 1 form field

    - by cf_PhillipSenn
    I'm trying to update the LastName field for PersonID. I can pass PersonID, but I don't know the syntax for also passing the LastName field. $('input[name="LastName"]').live('focusout', function() { var PersonID = $(this).parents("tr").attr("ID"); var LastName = $(this).val(); // todo: serialize $.ajax({ url:'Remote/Person.cfc?method=UpdateLastName&returnformat=json' ,data:'PersonID='+PersonID }); $(this).parents("td").empty().append(LastName); }); Q: Is is something like data:{'PersonID='+PersonID,'LastName='+LastName} Am I missing a squiggly line or a parenthesis or comma or dot or colon or semi-colon or something?

  • DataModelSelection on list exposed via EntityQuery

    - by Kalpana
    Is it possible to have support for enabling DataModelSelection on a list page paginated via EntityQuery? (All the examples load the list by performing a query on the @Factory method). But, I would like to re-use the existing pagination mechanism and just enable the ability to support DataModelSelection on it. I am also assuming that DataModelSelection is capable of tracking a single row in a List, how do we extend this to support a certain action (say deletion, activation ...) of multiple rows. I am a newbie and would appreciate any help on this topic. I have already gone through the samples shipped as part of Seam (booking, message). I have already posted this in seam users forum, but I am yet to get a response

  • ASP.NET MVC ,Maintaining Model State between Ajax requests

    - by Podders
    problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

What can I do to make sure that this file is interpreted as a CSS by firefox?

  • Only show activities from a specific gadget in OpenSocial

    - by corné
    I created a gadget which is able to post activities: function postActivity(text) { var params = {}; params[opensocial.Activity.Field.TITLE] = text; var activity = opensocial.newActivity(params); opensocial.requestCreateActivity(activity, opensocial.CreateActivityPriority.HIGH); }; And I request activities by doing: req.add(req.newFetchActivitiesRequest( new opensocial.IdSpec({'userId' : 'VIEWER', 'groupId' : 'FRIENDS'})), 'friends_activities'); My question is: How can I filter activities to only show activities posted by a specific gadget? I reckon the field "appId" is meant for this, but this field is empty in the response.

  • Display exception information and Debug.Print() messages in Immediate Window

    - by Timwi
    A friend of mine claims that calls to Debug.Print() as well as first-chance exception notifications appear in the Immediate Window for him. I found this surprising; for me they only appear in the Output Window. MSDN claims (here) that you can implicitly enable them in the Immediate Window by explicitly disabling them in the Output Window. But that doesn't work for me; the messages are not shown in either window if I disable this. The Immediate Window remains empty. How do I get the Immediate Window to display this information?

  • computing z-scores for 2D matrices in scipy/numpy in Python

    - by user248237
    How can I compute the z-score for matrices in Python? Suppose I have the array: a = array([[ 1, 2, 3], [ 30, 35, 36], [2000, 6000, 8000]]) and I want to compute the z-score for each row. The solution I came up with is: array([zs(item) for item in a]) where zs is in scipy.stats.stats. Is there a better built-in vectorized way to do this? Also, is it always good to z-score numbers before using hierarchical clustering with euclidean or seuclidean distance? Can anyone discuss the relative advantages/disadvantages? thanks.

  • JQuery Datatable Question: Centering column data after data insertion

    - by Chris
    I have a data table that is initially empty and is populated after a particular Javascript call. After the data is inserted into the table, I'd like to center all of the data in one of the columns. I tried specifying this at the initialization step in this way: dTable = $('#dt').datatable({ 'aoColumns': [ null, null, { "sClass" : "center" }] }); The data in the third column was not centered after the insertions were complete. I tried modifying aoColumns after the insertions and redrawing the table as well: dTable.fnSettings().aoColumns[2].sClass = "center"; dTable.fnDraw(); This did not work either. So my question is simply how should I go about telling the data table to center the data in the third column? Thanks in advance for your suggestions. Chris

  • Add mask to input

    - by Lodewijk Wensveen
    I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

  • DbDataReader with DbTransactions

    - by Gustavo Paulillo
    Its the wrong way or lack of performance, using DbDataReader combinated with DbTransactions? An example of code: public DbDataReader ExecuteReader() { try { if (this._baseConnection.State == ConnectionState.Closed) this._baseConnection.Open(); if (this._baseCommand.Transaction != null) return this._baseCommand.ExecuteReader(); return this._baseCommand.ExecuteReader(CommandBehavior.CloseConnection); } catch (Exception excp) { if (this._baseCommand.Transaction != null) this._baseCommand.Transaction.Rollback(); this._baseCommand.CommandText = string.Empty; this._baseConnection.Close(); throw new Exception(excp.Message); } } Some methods call this operation. Sometimes openning a DbTransaction. Its using DbConnection and DbCommand. The real problem, is in production enviroment (like 5,000 access/day) the ADO operations start throwing exceptions

  • jQuery detect current thumb and scroll jCarousel accordingly

    - by steve
    Another thanks to SLaks for helping me get the code this far. I'm not quite sure if my last step is even possible with the way I have things set up. A live version of the gallery can be seen here: http://www.studioimbrue.com/index2.php Currently, everything works appropriately. The image and its thumbnail are currently tied together, but the jCarousel itself is still independent. I've added nextThumb.closest('.thumbscontainer').jcarousel('next'); so that when you click the large image, the carousel scrolls to the next row, but that doesn't actually follow any logic. What I'm attempting to do is for jQuery to detect how far down the thumbnail is and when to appropriately scroll the carousel. Is this even possible?

  • How to customize the Visual Studio 2010 RC StartPage recent projects

    - by devlife

I see that it is binding to RecentProjects but where is that coming from?

  • Core Data Image Won't Load Into NSTableView Image Cell

    - by jcady
    In my code I am storing an image into my Core Data model (works fine). If I set up my view to have an NSImageView and bind its Data to Controller Key: selection and modelKeyPath: myImagePath, it works. It will show each image for the selected row. I then create a new column in my NSTableView and drag an image cell onto the column. However, I cannot get my Core Data bindings to have the image show up in the cell. I have tried binding both value and data, but no luck. Since I am sure the image is stored properly, what am I doing wrong in my binding to prevent the image from showing up in the table cell? Thanks so much. (My background: new Cocoa developer who has recently gone through the entire Hillegass book.)

  • Objective-C syntax

    - by mebFace
    I've been studying objective-c for a few days now. I keep coming across these two structures: NSString * somestring (NSString *) somestring I understand the first simply sets a pointer to an NSString object, but what does the second construct do, and when should I use it? What's the deal with the asterix marks? Sorry if this question doesn't make any sense, I am completely new to this language, and haven't even reached the level of asking proper questions. Main purpose -- I'm trying to decipher this method: -(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger) row forComponent: (NSInteger)component *Also, the classes I chose don't matter. *

  • Reshape data frame to convert factors into columns in R

    - by Alexander L. Belikoff
    I have a data frame where one particular column has a set of specific values (let's say, 1, 2, ..., 23). What I would like to do is to convert from this layout to the one, where the frame would have extra 23 (in this case) columns, each one representing one of the factor values. The data in these columns would be booleans indicating whether a particular row had a given factor value... To show a specific example: Source frame: ID DATE SECTOR 123 2008-01-01 1 456 2008-01-01 3 789 2008-01-02 5 ... <more records with SECTOR values from 1 to 5> Desired format: ID DATE SECTOR.1 SECTOR.2 SECTOR.3 SECTOR.4 SECTOR.5 123 2008-01-01 T F F F F 456 2008-01-01 F F T F F 789 2008-01-02 F F F F T I have no problem doing it in a loop but I hoped there would be a better way. So far reshape() didn't yield the desired result. Help would be much appreciated.

  • How to decompress/inflate an XML response from ASP

    - by krisg
    Can anyone provide some insight into how i'd go about decompressing an XML response in classic ASP. We've been handed some code and asked to get it working: Set oXMLHttp = Server.CreateObject("MSXML2.ServerXMLHTTP") URL = HttpServer + re_domain + ".do;jsessionid=" + ue_session + "?" + data oXMLHttp.setTimeouts 5000, 60000, 1200000, 1200000 oXMLHttp.open "GET", URL, false oXMLHttp.setRequestHeader "Accept-Encoding", "gzip" oXMLHttp.send() if oXMLHttp.status = 200 Then if oXMLHttp.responseText = "" then htmlrequest_get = "Empty Response from Server" else htmlrequest_get = oXMLHttp.responseText end if else ... Apparently now that the response is compressed using gzip, we have to un-compress the XML response before we can start to work with the data. How should i go about this?

  • ASP.Net: User controls added to placeholder dynamically cannot retrieve values.

    - by Steve Horn
    I am adding some user controls dynamically to a PlaceHolder server control. My user control consists of some labels and some textbox controls. When I submit the form and try to view the contents of the textboxes (within each user control) on the server, they are empty. When the postback completes, the textboxes have the data that I entered prior to postback. This tells me that the text in the boxes are being retained through ViewState. I just don't know why I can't find them when I'm debugging. Can someone please tell me why I would not be seeing the data the user entered on the server? Thanks for any help.
