• How to remove a single event in a recuring event

  - by albertos

  hi all. I' m having an issue with fullCalendar. I created a script that, adds an event to fullCalendar, along a day range, and set a unique id in order to have this event recur. let say for example that i have a recuring event from 1/1/10 till 10/1/10. i create 10 single event Objects with the same id, and place then on fullCalendar. my question is, that i want to exclude a single day over this recuring event. (for example 3/1/10). i found out, that if i remove that particural event from the sources table and then update the event its fine. but how can i get on runtime the actucal index of this eventObj on sources table? Note that, i add the events on the fullCalendar using the .fullCalendar("renderEvent") method. Thanks.

• Weird exception with OLEDB Parameter Insert

  - by Seamus MacKenzie

  Getting a strange error when trying to insert data into an Access database using parameters. the line where I am getting a problem is :- thisCommand.CommandText = "INSERT INTO Events (Venue_ID, Date_Start, Date_End, Time_Start, Time_End, Name, Description, Event_Type, Buy_Tickets_URL) VALUES (@VenID, @DStart, @DEnd, @evTime, @evTime, @Name, @Des, @EvType, @SysUrl);"; string desc = GetDesc(rec.EvName); thisCommand.Parameters.AddWithValue("@Des", desc); thisCommand.ExecuteNonQuery(); None of the other parameters cause a problem but when trying to insert data to the description field I get a database exception saying the field is too small to accept the amount of data. The problem is my program is only trying to insert 3 characters when it throws the error and the Description field is a memo so should be able to hold up to 65000+ characters. When inserting a value manually in the CommandText everything works fine so it must be something to do with the parameter properties.

• How to handle set based consistency validation in CQRS?

  - by JD Courtoy

  I have a fairly simple domain model involving a list of Facility aggregate roots. Given that I'm using CQRS and an event-bus to handle events raised from the domain, how could you handle validation on sets? For example, say I have the following requirement: Facility's must have a unique name. Since I'm using an eventually consistent database on the query side, the data in it is not guaranteed to be accurate at the time the event processesor processes the event. For example, a FacilityCreatedEvent is in the query database event processing queue waiting to be processed and written into the database. A new CreateFacilityCommand is sent to the domain to be processed. The domain services query the read database to see if there are any other Facility's registered already with that name, but returns false because the CreateNewFacilityEvent has not yet been processed and written to the store. The new CreateFacilityCommand will now succeed and throw up another FacilityCreatedEvent which would blow up when the event processor tries to write it into the database and finds that another Facility already exists with that name.

• Sync offline JQuery Mobile form

  - by Dimas

  My name is Dimas and I work as a developer in a hospital. I've developed a web form with JQuery Mobile which is accessed from an Android tablet. It sends data (text and FILES) to the server (PHP) and it's saved in a MySQL database. This tablets are used by doctors that are visiting the patients in their homes. Some of these patients live in remote areas with very bad Internet connection, so I'm thinking on use HTML5 Offline feature to solve these situations. I started reading about it but I'm newbie with this technology. I've some questions: Do you think this is the best/easiest solution? If I could save the form data in a local sqlite storage when the tablet is offline, how I could synchronize it with the data in MySQL server when the tablet become online? Thanks

• Plotting a cumulative graph of python datetimes

  - by ventolin

  Say I have a list of datetimes, and we know each datetime to be the recorded time of an event happening. Is it possible in matplotlib to graph the frequency of this event occuring over time, showing this data in a cumulative graph (so that each point is greater or equal to all of the points that went before it), without preprocessing this list? (e.g. passing datetime objects directly to some wonderful matplotlib function) Or do I need to turn this list of datetimes into a list of dictionary items, such as: {"year": 1998, "month": 12, "date": 15, "events": 92} and then generate a graph from this list? Sorry if this seems like a silly question - I'm not all too familiar with matplotlib, and would like to save myself the effort of doing this the latter way if matplotlib can already deal with datetime objects itself.

• How much time do you spend in Reflector? (.NET)

  - by mannu

  As a consultant I get to toy around with many different products and APIs as the customer demands we use X and Y. I think it is great fun and I learn a lot from it. What will make a great developer over time is, in my opinion, the will to understand and learn new things. Therefore, I will always try to understand what happens "behind the scenes" when I am using 3rd party products. I spend around 10-15% of my time in Reflector to learn what the heck I'm really doing when I call method X. How much time do you spend on average? This may also apply to reading (open) source code, documentation etc.

• ASP.Net - Gridview row selection and effects

  - by Clint

  I'm using the following code in attempt to allow the user to select a gridview row by clicking anywhere on the row (plus mouse over and out) effects. The code doesn't seem to be applied on rowdatabound and I can't break into the event. (It is wired). The control is in a usercontrol, that lives in a content page, which has a masterpage. protected void gvOrderTypes_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gvOrdTypes = (GridView)sender; //check the item being bound is actually a DataRow, if it is, //wire up the required html events and attach the relevant JavaScripts if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "javascript:setMouseOverColor(this);"; e.Row.Attributes["onmouseout"] = "javascript:setMouseOutColor(this);"; e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(gvOrdTypes, "Select$" + e.Row.RowIndex); } }

• Breakpoint when variable takes on a certain value.

  - by Mick

  I have something analogous to the following code... void function(int x) { // complicated operation on x blah blah } It all appears to be working fine except when x happens to be a particular value, say "273". But x being 273 is a rare event, 99.999% of the time it is some other value. Now I wish to observe the events when this function is called with x=273, so I would like to insert a breakpoint that gets hit only with x is that value. Perhaps I could do it like this: void function(int x) { if (x == 273) { // put breakpoint on this line. } // complicated operation on x blah blah } The problem is that presumably the compiler will optimise away this "if" statement because it doesn't do anything. So my question is what should I put within the "if" statement to to make sure it gets compiled in to something... or should I be tracing the x==273 case in some completely different way.

• Repeat over files in a File > Open dialog with Applescript

  - by GotNoSugarBaby

  In the below script I use an Application other than Finder to launch an "Open" browser and perform a search in it. I've got the window into the state I want, but whatever I try can't access the list of files to repeat over. If anyone can help by adding the code to repeat over that file list and log out the file path of each file it'd be a huge help. Thanks a lot. tell application "Preview" -- start the app activate -- let it boot up delay 3 -- ensure it still has focus activate end tell tell application "System Events" tell process "Preview" -- spawn "Open" window keystroke "o" using {command down} delay 0.5 -- spawn "Go to" window keystroke "g" using {command down, shift down} delay 0.5 -- expand scope of search to all of this mac keystroke "/" keystroke return delay 0.5 -- spawn search field keystroke "f" using {command down} delay 0.5 -- perform search keystroke ".jpg OR .jpeg" keystroke return end tell end tell

• How do I query through a many-to-many relationship using NHibernate Criteria and Lambda Extensions?

  - by Brian Kendig

  In my database I have a Person table and an Event table (parties, meetings, &c.). This many-to-many relationship is represented through an Invitation table. Each Person can have many Invitations. Each Event can also have many Invitations. If I want a list of Events to which a Person is invited, I can use this HQL query: IQuery query = Session.CreateQuery("SELECT i.Event from Invitation i where i.Person = :p"); query.SetParameter("p", person); return query.List<Person>(); How would I write this query with NHibernate criteria and Lambda Extensions?

• What to read as a good quick review and intro into development process methodologies?

  - by Ivan

  Being mostly self-taught freestyle developer and having no experience of working in teams of professionals in serious software companies, having only a very general idea of how the software development is should really be done, I think I've came to a point, when I begin struggling from lack of order in my work. I think I should get acquainted with professional software development technologies to optimize my own productivity and to extend my choice of work by increasing capabilities to work in teams and bigger companies. What should I begin with? Of course I am googling on this subject right now, but maybe hou have some real experience based recommendations to share?

• What are some good ways to promote my Android application?

  - by Bryan Denny

  I'm a new Android developer and I just released a free, open source tipping calculator app called Tippy Tipper. I created this app to get myself familiar with Android and to hopefully provide a good example app for other new developers to look at. Now that I've overcome the challenges of learning how to program, test and release my Android app, I've come across a new challenge: marketing! What are some good ways to promote my app to the Android community? Can anyone with some experience talk about how they did this successfully with their own app?

• Detecting extended mousedown event on iPhone

  - by Alan Neal

  I want to detect an extended mousedown. The following code works in Firefox and Safari... var mousedownTimeout; $('#testButton').mousedown(function(){ mousedownTimeout = window.setTimeout(function(){ alert("Hey, let go."); }, 2000); }); $('#testButton').mouseup(function(){ window.clearTimeout(mousedownTimeout); }); ... but not on the iPhone because (quoting quirksmore.org)... The iPhone fires the mousedown, mouseup and click events in the correct order on a click (tap), but it either fires all three or none at all. Is there a way around this?

• Does this popup view violate HIGS?

  - by brettr

  Will using a popup view to present a comment submission form violate the HIGS? I may have one popup with selections that goes to the final popup. Two popups back to back. This is more similar to a modal type of view than an alert or action sheet as described by the HIGS: http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/MobileHIG/ModalViews/ModalViews.html#//apple_ref/doc/uid/TP40006556-CH11-SW1 under the section 'Using Modal Views'. Basically the type of view I'm shooting for is a combination of an alert with a custom view. It's sort of a mini view since it will be centered in the middle of the screen but not take up all of the viewing area. I'm fairly sure that is a violation however, but I'm looking for a few opinions on it. I believe what needs to happen is use a modal view, which will cover the entire view.

• Data Warehouse: One Database or many?

  - by drrollins

  At my new company, they keep all data associated with the data warehouse, including import, staging, audit, dimension and fact tables, together in the same physical database. I've been a database developer for a number of years now and this consolidation of function and form seems counter to everything I know. It seems to make security, backup/restore and performance management issues more manually intensive. Is this something that is done in the industry? Are there substantial reasons for doing or not doing it? The platform is Netezza. The size is in terabytes, hundreds of millions of rows. What I'm looking to get from answers to this question is a solid understanding of how right or wrong this path is. From your experience, what are the issues I should be focused on arguing if this is a path that will cause trouble for us down the road. If it is no big deal, then I'd like to know that as well.

• How can I test Windows Error Reporting?

  - by Deneb Meketa

  My company participates in Windows Error Reporting via Winqual. We'd like to add some additional data to our crash reports, using WERRegisterMemoryBlock. Obviously we'd like to make sure this is working before we ship our next version. How can we test it? Is there a way to locally preview precisely what is going to be sent? Does this realistically reproduce what we are going to be able to retrieve from Winqual? Alternatively, can we generate a real report from a developer machine, then retrieve the report from Winqual? How would we distinguish this test case from the rest of our Winqual data?

• Isuue when uploading new version to app store

  - by user2978997

  Can I use new certificate and provisioning profile to upload new version? We have discovered one or more issues with your recent delivery for "EMTV News". To process your delivery, the following issues must be corrected: Invalid Provisioning Profile - The provisioning profile included in the bundle com.pointabout.C1E322F0 (Payload/EMTV.app) is invalid. (Missing code-signing certificate.) For more information, visit the iOS Developer Portal. Once these issues have been corrected, go to the Version Details page and click "Ready to Upload Binary." Continue through the submission process until the app status is "Waiting for Upload." You can then deliver the corrected binary. Regards, The App Store team Note: I am using new Certificate and provisioning profile but same bundle ID which is being used in old version of the app.

• Constantly changing frameworks/APIs - how do we keep up?

  - by Jamie Chapman

  This question isn't really for any specific technology but more of general developer question. We all know from experience that things change. Frameworks evolve, new features are added and stuff gets removed. For example, how might a product using version 1.0 of the "ABC" framework adapt when version 2.0 comes along (ABC could be .NET, Java, Cocoa, or whatever you want)? One solution might be to make the frameworks backward compatible; so that code written for 1.0 will still work in version 2.0 of the framework. Another might be to selectively target only version 1.0 of the framework, but this might leave many fancy new features unused (many .NET 2.0 apps seem to do this) Any thoughts on what we as developers should do as best practice to keep our technologies up to date, whilst not breaking our applications?

• Error whenever a java applet is loaded

  - by Mudtail

  Hi. For the past few months or so, I've been getting an error whenever I attempt to use a java applet. I'm getting this error on every browser I use, and I get the error occasionally in linux, too. The java applet loads for roughly 5 seconds or so, then it stops and I get two error messages, stating that an exception occurred (java.io.EOFException). This seems to happen regardless of what website I'm using. Going to the website shows I'm running java 6 update 20, and I get no error. Googling the error turns up nothing useful - I'm not a java developer, so most of the results don't apply to me at all. My question is this. What's causing this error, and what can I do to fix whatever issue is causing it?

• Agile version control?

  - by Paul Dixon

  I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?

• Application disappears after starting - C++ linking managed code dll

  - by Axarydax

  Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP3 x86, and all applications linking managed code dll do not work. After starting the .exe seemingly nothing happens, no window pops up, no memory gets eaten, no task shows in task manager, nothing, nada. Event log is empty, everything is just as if the application returned to the OS right after the start. I am at loss about this, I really don't know how should I start even debugging this problem. I don't want to install VS2010 and everything onto a Windows XP box, I'd like to try something less time intensive first. This all is happening just to native C++ apps that link managed c++ DLL. Pure managed C# apps do work. Pure native C++ apps do work.

• How to create a 'Hot or Not' website

  - by Casper

  Hi guys, I'd like to create a website with similar concept as 'Hot or Not' where users need to sign up to the website and then upload photos. Each photo can be given a description and some additional fields. Other users may comment and rate the photo entries. On top of that, users may favourite/bookmark (and remove) any photo entries and they're accessible via their profile page That's generally how the website will be. Can't decide on a CMS to use Somehow I'm at a crossroad here. I've done some research and found that Joomla has an extension that is able to pull this website off but the thing is I'm not that comfortable with using Joomla. I work with WordPress most of the time, but I can't seem to figure out how would I build this website with WordPress. Would using BuddyPress make it work? Would hiring a plugin developer to customize some plugins work? What do you guys think?

• Inherit appenders from calling instance in log4j or logback

  - by Lord.Quackstar

  In my program I have 2 separate streams of logging events (calling them streams for simplicity, in reality its 2 appenders). Stream1 contains client logging and Stream2 contains control logging. Now this might seem easy, except that certain classes can be both in the client logging and server logging, depending on the situation. Complicating this further is the fact that a command that a client wants takes place in 2 separate threads (one being fetched randomly from a thread pool), so any kind of tracking with MDC or NDC isn't possible. What would really simplify this is if the logger could inherit the appenders from the calling instance. That way I can setup 2 appenders for 2 loggers and be done. However I have no idea how to do it cleanly or easily. Can anyone offer any advice on how to do so? Note: If something needs to be passed around, I do have a event bean that gets passed to everything in the chain that can be used if necessary.

• Windows azure deployment

  - by smoothe

  I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.
