• DoFactory Architecture Design

  - by Brendan Vogt

  Hi, Has anybody used the Patterns in Action from the Do Factory? I just have a question on the architecture. I always thought that the service must call the repository. In the solution the have ActionService and a repository. Lets say I want to get all the customers then in my controller I would call the repository's GetCustomers method. This will then call ActionService's GetCustomer's method. And then lastly another GetCustomers method is called in the customer data access object. Is this right? Any comments on the way that they implemented things in the Patterns in Action?

• Android - Temporal & Ancestral Navigation with ViewPager & Fragments

  - by rascuache

  I'm trying to work out the best way to implement the 'ancestral' and 'temporal' navigation (utilising the up button and back buttons), for a music player I'm working on. Currently, the user is presented with a viewpager, and can page between three main fragments (ArtistMain, AlbumMain and SongMain). Upon choosing an item inside that view, a fragment transaction occurs, and the viewpager goes out of view, replaced by a new fragment (AlbumSub, Songsub or player, depending on where the user came from). The user can then navigate deeper, until a song is chosen, and then they are taken to the 'player' screen. I guess the question is: How do I implement all of this conditional navigation? I'm fairly new to android and programming in general, and I just can't seem to come up with an efficient way to achieve this. At the moment, as each fragment is brought into view, the app is checking to see where the user just came from, and then determines where the user should be taken if back or home is called. This means I have a booleans like "fromArtistMain", "fromAlbumSub", and I'm checking for things like "fromSongSub && fromPlayer".. it's all turning into a bit of a mess. I've drawn a diagram (in paint, sorry!!), to depict the navigation I'm trying to achieve. The yellow represents the 'up' button press, the red is the 'back' button press, and blue is just normal navigation. The green arrows are meant to represent the view paging: Any advice is welcome. It might take something really simple that I've just overlooked. Thanks for your time.

• How do I get rid of these warnings?

  - by Brian Postow

  This is really several questions, but anyway... I'm working with a big project in XCode, relatively recently ported from MetroWorks (Yes, really) and there's a bunch of warnings that I want to get rid of. Every so often an IMPORTANT warning comes up, but I never look at them because there's too many garbage ones. So, if I can either figure out how to get XCode to stop giving the warning, or actually fix the problem, that would be great. Here are the warnings: It claims that <map.h> is antiquated. However, when I replace it with <map> my files don't compile. Evidently, there's something in map.h that isn't in map... this decimal constant is unsigned only in ISO C90 This is a large number being compared to an unsigned long. I have even cast it, with no effect. enumeral mismatch in conditional expression: <anonymous enum> vs <anonymous enum> This appears to be from a ?: operator. Possibly that the then and else branches don't evaluate to the same type? Except that in at least one case, it's (matchVp == NULL ? noErr : dupFNErr) And since those are both of type OSErr, which is mac defined... I'm not sure what's up. It also seems to come up when I have other pairs of mac constants... multi-character character constant This one is obvious. The problem is that I actually NEED multi-character constants... -fwritable-strings not compatible with literal CF/NSString I unchecked the "Strings are Read-Only" box in both the project and target settings... and it seems to have had no effect...

• New programming jargon you coined?

  - by jdk

  What programming terms have you coined that have taken off in your own circles? (i.e. have heard others repeating it?) It might be within your own team, workplace or garnered greater popularity on the Internet. Define your programming term, word or phrase in bold followed by an explanation, citation and/or usage example so we can use it in appropriate context. This question serves in the spirit of communication among programmers through sharing of terminology with each other, to benefit us by its propagation within our own teams and environments. Please no repeats of common jargon already ingrained in the programming culture like: "kludge", "automagically", "cruft", etc. (unless you coined it). Stealing from the comments: A shared vocabulary is the basis of communication, not just among programmers, Note: This Programming question has been reworded/reorganized to phrase a real question and remove ambiguity, vagueness and rhetorical device. It is not difficult to know what is being asked & question can be reasonably answered (see answers below).

• How do you keep track of your programming TODOs?

  - by Simucal

  I'm one of those people who can't get anything done without a to-do list. If it isn't on the list it doesn't exist. Notepad Method: When I'm programming I've been keeping notepad open with a list of to-do's for my current project. I'll constantly re-arrange these based off priority and I cross them off and move them to the completed section when I'm finished with that particular task. Code Comments: Some programmers pepper their projects source code with: // TODO: Fix this completely atrocious code before anyone sees it Plus, I know that there are some tools that show you a list of all TODOs in your code as well. Website Task Tracker: Remember The Milk Backpack Manymoon Voo2do Gmail Tasks TeuxDeux TodoDodo Ta-da lists ... and many more What have you found to be the best method of keeping track of your to-do lists for multiple projects? Related Question: What can someone do to get organized around here? Related Question: Getting Organized; the to-do list.

• Holiday Approval /tracking

  - by nav

  Hi, Has anyone implemented a holiday workflow approval / tracking list in MOSS Sharepoint 2007? Can anyone suggests other solutions? The solution below works fine but I am specifically looking for a way to lookup manager of the user who created the holiday request list item in the workflow. I have followed this link http://www.u2u.info/Blogs/Kevin/Lists/Posts/Post.aspx?ID=39 which shows you how to create a custom workflow approval. Below are the steps outlined by the link. User add new holiday item to list Workflow kicks off Wf has the manager hardcoded (need a way to look this up, maybe from AD??) and creates a Task for them to review the request. If desired, this can include an email notification of the task Manager reviews, adds comments and approves/denies request User is notified of completed request Many Thanks, Naveen

• Log4j - Logging to multiple log files based on the project modules

  - by Veera

  Consider this scenario: I have a project with two modules and one common module as below (the package structure): com.mysite.moduleone com.mysite.moduletwo com.mysite.commonmodule In the above, the commonmodule classes can be used by other two modules. The question: I need to configureLog4J such a way that the log messages from moduleone and moduletwo goes to different log file. I can always do this using using category. But the real problem is when I want to log the messages from the commonmodule also. So, when the commonmodule classes are called from moduleone the commonmodule log messages should go to the moduleone log file. If the commonmodule is accesse from moduletwo the commonmodule log messages should go to moduletwo log file. Is it possible to configure Log4J in this fashion? Any comments? PS: I think I made my question clear. If any confusion, leave a comment, wil try to clear it. :)

• Lookup Field as a Site Column via CAML

  - by Rob Windsor

  I'm trying to create a Lookup Field as a Site Column via CAML. The list I want to use as the source of the lookup is created in the Feature Receiver so I don't know it's ID. I've read several blog posts that indicate that I can just put the path to the list in the List attribute. It seems from the comments on these post that this solution works for some people but not for others. I'm in the latter group. When I try to associate a content type that uses the lookup site column I: "Exception from HRESULT: 0x80040E07" <Field ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" StaticName="Test_x0020_Lookup_x0020_Column" DisplayName="Test Lookup Column" Type="Lookup" Required="FALSE" List="Lists/Test" ShowField="Title" PrependId="TRUE" Group="Test Site Columns" /> <ContentType ID="0x0100B6D92594DDCE8E479D0EB0C414C463B0" Name="Test Lookup Content Type" Version="0" Group="Test Content Types"> <FieldRefs> <FieldRef ID="{da94e56b-428f-4b95-b4c6-24aed0256475}" Name="Test_x0020_Lookup_x0020_Column" Required="TRUE" /> </FieldRefs> </ContentType>

• Can't find a Wordpress image/photo gallery plugin

  - by mgroves

  I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

• Advice on simple efficient way to store web form data when no db/auth required

  - by ted776

  Hi, I have a situation where I need to provide an efficient way to process and store comments submitted via a web form. I would normally use PHP and either MySQL or XML to store the data, but this is slightly different in that this web form will only be temporarily available in a closed LAN environment, and all i need to do is process the form data and store it a format which can be accessed by another application on the LAN (Adobe Director). Each request made by the Director app should pop the stack of data. I'm wondering how best to store the data for this type of situation as it's not something I would normally do. I'm thinking possibly storing the data in an XML file, but any advice would be great!

• Immutable Dot Net strings

  - by klork

  I usually define my string variables in vb.net as Dim f_sName as string=String.Empty f_sName = "foo" Given the immutable nature of strings in .net, is there a better way to initialize strings and deal with the "Variable 'f_sName ' is used before it has been assigned a value. A null reference exception could result at runtime." warning? Also for classes that do not have constructors which accept no arguments such as System.Net.Sockets.NetworkStream, what is the best way to define and initialize a variable of that type? All comments are highly appreciated. Thanks

• Get controls ClientID/UniqueID between DetailsView and UpdatePanel

  - by robertpnl

  Hi guys, I like to know how to get the ClientID/UniqueID of a control inside a Detailsview controls EditItemTemplate element and when DetailsViews changing to Edit mode and DetailsView is inside a AJAX UpdatePanel. Without UpdatePanel, during PostBack I can get the ClientID's control, but now with an UpdatePanel. <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="SqlDataSource1" AllowPaging="true" AutoGenerateEditButton="true"> <Fields> <asp:TemplateField> <EditItemTemplate> <asp:CheckBox runat="server" ID="chkboxTest" Text="CHECKBOX" /> </EditItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> </ContentTemplate> </asp:UpdatePanel> As you see, the EditItemTemplate contains a Checkbox control. So i'm trying to get the ClientID of this checkbox when Detailsview is changing to the Edit mode. I need this value for handling Javascript. Catching the events ChangingMode/ChangedMode doesn't work; chkbox is null: void DetailsView1_ModeChanged(object sender, EventArgs e) { if (DetailsView1.CurrentMode == DetailsViewMode.Edit) var chkbox = DetailsView1.Rows[0].FindControl("chkxboxTest"); // <== is null } Maybe i'm using the wrong event? Someone can give me a tip about this? Thanks.

• Problem with SQL syntax (probably simple)

• NHibernate Named Query Parameter Numbering @p1 @p2 etc

  - by IanT8

  A colleague recently ran into a problem where he was passing in a single date parameter to a named query. In the query, the parameter was being used twice, once in an expression and once in a GROUP BY clause. Much to our surprise, we discovered that NHibernate used two variables and sent the single named parameter in twice, as @p1 and @p2. This behaviour caused SQL to fail the query, with the usual "a column in the select clause is not in the group by clause" (I paraphrase ofcourse). Is this behaviour normal? Can it be changed? Seems to me that if you have a parameter name like :startDate, NHibernate only needs to pass in @p1 no matter how many times you might refer to :startDate in the query. Any comments? The problem was worked around by using another sub-query to overcome the SQL parsing error.

• basic question with a dtd

  - by voodoomsr

  i need an element with the characteristics <!ELEMENT section ((comment*)|definition|(comment*))> but that is ambiguous, i get the next message in visual studio Multiple definition of element 'comment' causes the content model to become ambiguous. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence. So how can i write correctly that? the correct structure is one definition surrounded by possibles comments elements.

• After Trigger execute before constraint check in oracle

  - by satakare

  Hi, I have After Insert/Update trigger on Table T1 which get the referential data for Col1 from T2 and does some work and insert it into another table. The col1 is FK to Table T2.

But when trigger is enabled and user insert the wrong value in Col1 trigger is getting fired and shows the 'no data found' error message. Actually I am expecting the table to throw constraint error, but trigger is throwing it. Please let me know your comments about this trigger behaviour.

• Incorporate Wordpress into Kohana 3

  - by alex

  I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

• Wordpress : display all articles of a month on one page

  I would like to change the default behavior of Wordpress regarding the number of articles displayed on a same page to be the following : when displaying the home page, the 10 most recent articles should be displayed, 10 being the setting which can be changed through the admin panel (posts_per_page) when displaying the articles of a specific month (given through the URL like this : ?m=200906&order=ASC, I'd like to display on the same page all articles of this month (in other words, I don't want to have to browse through articles using previous entries or next entries.

Is this possible to do ? How ?

• What is the best way to add categories to posts - Ruby on Rails blog...

  - by bgadoci

  I am new to Ruby and Rails so bear with me please. I have created a very simple blog application with both posts and comments. Everything works great. My next question regarding adding categories. I am wondering the best way to do this. As I can't see too far in front of me yet when it comes to Rails I thought I would ask. To be clear, I would like that a single post can have multiple categories and a category can have multiple posts. Is the best way to do this to create a 'categories' table and then use the posts and categories models to do has_many :posts, has_many :categories? Would I also then set the routes.rb such that posts are embedded under categories? Or is there an easier way by simply adding a category column to the existing posts table? (in which case I would imagine having multiple categories would be difficult).

• Invalid Token when using XPath

  Hi I am making a modification to a web application using XPath, and when executed I get an error message - Invalid token! This is basic what I am doing public xmlNode GetSelection (SelectParams params, xmldocument docment) { xpathstring = string.format("Name =\'{0}' Displaytag = \'{1}' Manadatory=\'{2}', params.Name, params.Displaytag, params.Manadatory); return document.selectsinglenode(xpathstring); } As you can see, I am making a string and setting values on the nodes I am trying to find against my xml document, and thus returning xml data that matches my parameters. What is happening is that I am getting an xpathexeception error in Visual Studio and it says invalid token. I do know that in the xml document that the parameters I am looking in the tags have double quotes, for example, Name="ABC". So, I thought the problem could be solved using an "\". Can anyone help?
