• Drawing custom graphics on the iPhone: CALayer vs. CGContext

  - by Henry Cooke

  Hi all, I have an application in which I'm doing some custom drawing, a bunch of lines on a gradient background, like so (ignore the text, they're just UILabels): At the moment, that's all done by starting a new CGContext, drawing stuff into it with CGContextDrawLinearGradient and CGContextStrokePath, then finally saving the resulting image with UIGraphicsGetImageFromCurrentImageContext. The positioning info is calculated while I'm laying out those labels, so it'd be a PITA (and duplication of effort) to calculate it all over again when the containing UIView is drawn with drawRect, so I'm drawing it ahead of time into a UIImage. All works fine, so far so good. However, I have a sneaking suspicion that it may be more efficient to use CALayers to do this drawing. My (cursory) understanding of the difference between the two approaches is that a CALayer is more like a bunch of instructions to draw stuff, and so takes up less memory until it's actually drawn onscreen, whereas drawing everything into a UIImage ahead of time means that you've got a sodding great bitmap kicking around in memory all the time, whether it's drawn or not. Is that a correct understanding? What is generally considered to be the best way of drawing custom images on the iPhone?

• using SeekToNavCuePoint with Custom Cue Points created by ActionScript

  - by meghana

  i have custom flvPlayBack player, i want to do like add Custom CuePoints using ActionScript and making one button Event , On click of that button , Flv should seek to that CuePoints added using ActionScript . I am using below code to do that. var rtn_obj:Object; //create cue point object my_FLVPlybk.source = "sj_clip.flv"; my_FLVPlybk.addASCuePoint(0, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(4, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(8, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(12, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(16, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(20, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(24, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(28, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.addASCuePoint(31, "abs",CuePointType.ACTIONSCRIPT); my_FLVPlybk.setFLVCuePointEnabled(true,"abs"); fwbtn1.addEventListener(MouseEvent.CLICK,Forward) function Forward(e:MouseEvent):void { if(rtn_obj != null) { traceit(rtn_obj) rtn_obj = my_FLVPlybk.findNextCuePointWithName(rtn_obj); if(rtn_obj != null) { traceit(rtn_obj) my_FLVPlybk.seekToNavCuePoint(rtn_obj.time); } } } my_FLVPlybk.addEventListener(fl.video.VideoEvent.READY, ready_listener); function ready_listener(eventObject:fl.video.VideoEvent):void { rtn_obj = my_FLVPlybk.findCuePoint("abs", CuePointType.ACTIONSCRIPT); } function traceit(cuePoint:Object):void { trace("Cue point name is: " + cuePoint.name); trace("Cue point time is: " + cuePoint.time); trace("Cue point type is: " + cuePoint.type); } I thought ,this code should work properly.. but when i run this code , it give me next cuePoint which i find using findNextCuePointWithName() method but it does not seek to that point , which i thought seekToNavCuePoint() method should do. anybody have any idea , how to make it work?? Thanks i Hope my i have explained my requirement to clear to understand. i really need this in urgent. please help me.

• Android "single top" launch mode and onNewIntent method

  - by Rich

  I read in the Android documentation that by setting my Activity's launchMode property to singleTop OR by adding the FLAG_ACTIVITY_SINGLE_TOP flag to my Intent, that calling startActivity(intent) would reuse a single Activity instance and give me the Intent in the onNewIntent callback. I did both of these things, and onNewIntent never fires and onCreate fires every time. The docs also say that this.getIntent() returns the intent that was first passed to the Activity when it was first created. In onCreate I'm calling getIntent and I'm getting a new one every time (I'm creating the intent object in another activity and adding an extra to it...this extra should be the same every time if it was returning me the same intent object). All this leads me to believe that my activity is not acting like a "single top", and I don't understand why. To add some background in case I'm simply missing a required step, here's my Activity declaration in the manifest and the code I'm using to launch the activity. The Activity itself doesn't do anything worth mentioning in regards to this: in AndroidManifest.xml: <activity android:name=".ArtistActivity" android:label="Artist" android:launchMode="singleTop"> </activity> in my calling Activity: Intent i = new Intent(); i.putExtra(EXTRA_KEY_ARTIST, id); i.setClass(this, ArtistActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); startActivity(i);

• Android: How can I validate EditText input?

  - by Stefan

  I need to do form validation on a series of EditTexts. I'm using OnFocusChangeListeners to trigger the validation, but this doesn't behave as desired for the final EditText. If I click on the "Done" button while typing into the final EditText then the InputMethod is disconnected, but technically focus is never lost on the EditText (and so validation never occurs). What's the best solution? Should I be monitoring when the InputMethod unbinds from each EditText rather than when focus changes? If so, how?

• Using OLEDB parameters in .NET when connecting to an AS400/DB2

  - by Jeff Stock

  I have been pulling my hair out trying to figure out what I can't get parameters to work in my query. I have the code written in VB.NET trying to do a query to an AS/400. I have IBM Access for Windows installed and I am able to get queries to work, just not with parameters. Any time I include a parameter in my query (ex. @MyParm) it doesn't work. It's like it doesn't replace the parameter with the value it should be. Here's my code: I get the following error: SQL0206: Column @MyParm not in specified tables Here's my code: Dim da As New OleDbDataAdapter Dim dt As New DataTable da.SelectCommand = New OleDbCommand da.SelectCommand.Connection = con da.SelectCommand.CommandText = "SELECT * FROM MyTable WHERE Col1 = @MyParm" With da.SelectCommand.Parameters .Add("@MyParm", OleDbType.Integer, 9) .Item("@MyParm").Value = 5 End With ' I get the error here of course da.Fill(dt) I can replace @MyParm with a literal of 5 and it works fine. What am I missing here? I do this with SQL Server all the time, but this is the first time I am attempting it on an AS400.

• Sql Query - Limiting query results

  - by Gublooo

  I am quite certain we cannot use the LIMIT clause for what I want to do - so wanted to find if there are any other ways we can accomplish this. I have a table which captures which user visited which store. Every time a user visits a store, a row is inserted into this table. Some of the fields are shopping_id (primary key) store_id user_id Now what I want is - for a given set of stores, find the top 5 users who have visited the store max number of times. I can do this 1 store at a time as: select store_id,user_id,count(1) as visits from shopping where store_id = 60 group by user_id,store_id order by visits desc Limit 5 This will give me the 5 users who have visited store_id=60 the max times What I want to do is provide a list of 10 store_ids and for each store fetch the 5 users who have visited that store max times select store_id,user_id,count(1) as visits from shopping where store_id in (60,61,62,63,64,65,66) group by user_id,store_id order by visits desc Limit 5 This will not work as the Limit at the end will return only 5 rows rather than 5 rows for each store. Any ideas on how I can achieve this. I can always write a loop and pass 1 store at a time but wanted to know if there is a better way

• How to set properties of a d:DesignInstance in XAML?

  - by Scott Bilas

  I'm using the new d:DesignInstance feature of the 4.0 series WPF tools. Works great! Only issue I'm having is: how can I set properties on the instance? Given something like this: <Grid d:DataContext="{d:DesignInstance plugin:SamplePendingChangesViewModel, IsDesignTimeCreatable=True}"/> How can I set properties on the viewmodel, aside from setting them in its default ctor or routing it through some other object initializer? I gave this a try but VS gives errors on compile "d:DataContext was not found": <Grid> <d:DataContext> <d:DesignInstance IsDesignTimeCreatable="True"> <plugin:SamplePendingChangesViewModel ActiveTagIndex="2"/> </d:DesignInstance> </d:DataContext> For the moment I'm going back to using a resource and 'd:DataContext={StaticResource SampleData}', where I can set the properties in the resource. Is there a way to do it via a d:DesignInstance?

• Stresstesting ASP.NET/IIS with WCAT

  I'm trying to setup a stress/load test using the WCAT toolkit included in the IIS Resources. Using LogParser, I've processed a UBR file with configuration. It looks something like this: [Configuration] NumClientMachines: 1 # number of distinct client machines to use NumClientThreads: 100 # number of threads per machine AsynchronousWait: TRUE # asynchronous wait for think and delay Duration: 5m # length of experiment (m = minutes, s = seconds) MaxRecvBuffer: 8192K # suggested maximum received buffer ThinkTime: 0s # maximum think-time before next request WarmupTime: 5s # time to warm up before taking statistics CooldownTime: 6s # time to cool down at the end of the experiment [Performance] [Script] SET RequestHeader = "Accept: */*\r\n" APP RequestHeader = "Accept-Language: en-us\r\n" APP RequestHeader = "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705)\r\n" APP RequestHeader = "Host: %HOST%\r\n" NEW TRANSACTION classId = 1 NEW REQUEST HTTP ResponseStatusCode = 200 Weight = 45117 verb = "GET" URL = "http://Url1.com" NEW TRANSACTION classId = 3 NEW REQUEST HTTP ResponseStatusCode = 200 Weight = 13662 verb = "GET" URL = "http://Url1.com/test.aspx" Does it look OK?

• NHibernate, Databinding to DataGridView, Lazy Loading, and Session managment - need advice

  - by Tom Bushell

  My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running. For performance reasons, I set the convention DefaultLazy.Always() for all DB access. So far, the only way I've found to make this work is to keep a Session (let's call it MainSession) open all the time for the main form, so NHibernate can lazy load new data as the user navigates with the grid. Another part of the application can run in the background, and Save to the DB. Currently, (after considerable struggle), my approach is to call MainSession.Disconnect(), create a disposable Session for each Save, and MainSession.Reconnect() after finishing the Save. Otherwise SQLite will throw "The database file is locked" exceptions. This seems to be working well so far, but past experience has made me nervous about keeping a session open for a long time (I ran into performance problems when I tried to use a single session for both Saves and Loads - the cache filled up, and bogged down everything - see http://stackoverflow.com/questions/2526675/commit-is-very-slow-in-my-nhibernate-sqlite-project). So, my question - is this a good approach, or am I looking at problems down the road? If it's a bad approach, what are the alternatives? I've considered opening and closing my main session whenever the user navigates with the grid, but it's not obvious to me how I would do that - hook every event from the grid that could possibly cause a lazy load? I have the nagging feeling that trying to manage my own sessions this way is fundamentally the wrong approach, but it's not obvious what the right one is.

• MS Chart control with WPF C#

  - by Birgir Hrafn Sigurðsson

  Hello, Ive got a MS Chart control and it works just fine except that I can't figure out how to "format" the Y-Axis. I am adding a lot of double numbers into a Serie but when the double numb are actually whole numbers (20.000000.....) the Y-Axis on my chart shows 20. example: this serie : 12.32 11.00 10.13 would actually show up like this: 12.32 11 10.13 I have tried formatting the data as I insert it into the serie like this: serie.Points.AddXY(date.ToString(),double[i].ToString("##.##")); but that doesn't seem to work. I've tried to search for a place to format it in Chart.Series[0].* and Chart.ChartAreas[0].* but I didn't find it there. Thanks in advance, Regards, Birgir Hrafn

• Database design for summarized data

  - by holden

  I have a new table I'm going to add to a bunch of other summarized data, basically to take some of the load off by calculating weekly avgs. My question is whether I would be better off with one model over the other. One model with days of the week as a column with an additional column for price or another model as a series of fields for the DOW each taking a price. I'd like to know which would save me in speed and/or headaches? Or at least the trade off. IE. ID OBJECT_ID MON TUE WED THU FRI SAT SUN SOURCE OR ID OBJECT_ID DAYOFWEEK PRICE SOURCE

• AS 400 Performance from .Net iSeries Provider

  - by Nathan

  Hey all, First off, I am not an AS 400 guy - at all. So please forgive me for asking any noobish questions here. Basically, I am working on a .Net application that needs to access the AS400 for some real-time data. Although I have the system working, I am getting very different performance results between queries. Typically, when I make the 1st request against a SPROC on the AS400, I am seeing ~ 14 seconds to get the full data set. After that initial call, any subsequent calls usually only take ~ 1 second to return. This performance improvement remains for ~ 20 mins or so before it takes 14 seconds again. The interesting part with this is that, if the stored procedure is executed directly on the iSeries Navigator, it always returns within milliseconds (no change in response time). I wonder if it is a caching / execution plan issue but I can only apply my SQL SERVER logic to the AS400, which is not always a match. Any suggestions on what I can do to recieve a more consistant response time or simply insight as to why the AS400 is acting in this manner when I was using the iSeries Data Provider for .Net? Is there a better access method that I should use? Just in case, here's the code I am using to connect to the AS400 Dim Conn As New IBM.Data.DB2.iSeries.iDB2Connection(ConnectionString) Dim Cmd As New IBM.Data.DB2.iSeries.iDB2Command("SPROC_NAME_HERE", Conn) Cmd.CommandType = CommandType.StoredProcedure Using Conn Conn.Open() Dim Reader = Cmd.ExecuteReader() Using Reader While Reader.Read() 'Do Something End While Reader.Close() End Using Conn.Close() End Using

• Error reading in date using Zoo in R

  - by SASnewby

  I am trying to use the Zoo package to read in daily observations which do not occur on each day. The date format looks like this, and it is in the first column of dataset: 25-May-07 The command I use is: z <- read.zoo("multiplier7.csv", sep = ";", header = TRUE, format="%d-%b-%y") I get this error: Error in strptime(x, format, tz = "GMT") : input string is too long First question is: 1. Is Zoo the right package to use if I want to use lm regression with a spline time dummy? The bs command does not work because I need to convert it into a time series. 2. Why is this error occurring and how to fix?

• Using PSExec from within CruiseControl .NET

  - by JayRu

  Hi All, I'm trying to call a PSExec task from CC.NET and running into some difficulties. Here's the CC project <project name="Test"> <tasks> <exec> <executable>C:\Utilities\psexec.exe</executable> <buildArgs>-u [UNAME] -p [PWD] "C:\Utilities\Joel.bat"</buildArgs> </exec> </tasks> </project> Here's the source of Joel.bat CLS @ECHO OFF What happens is that the first time I force the project to build, it runs successfully. The PSExec task is kicked off and the Joel.bat file is executed. I get some information in the build log about exit codes, but the task is successful. Here's the build log output. PsExec v1.97 - Execute processes remotely Copyright (C) 2001-2009 Mark Russinovich Sysinternals - www.sysinternals.com C:\Utilities\Joel.bat exited with error code 0. The second time I force the build I get the dreaded "The Application failed to initialize properly (0xc0000142)" error message. I can't ever run the build more than once More so, if I try to shut down the cruise control .net service from within the services MSC, it can't. It's like there's a lock somewhere that is taken and not released. The only way I can kill the service is by killing the ccservices.exe process. I've tried the exact same thing using an nant task and gotten the exact same results. It works the first time, and fails the second and I can't shutdown the process. I'm not sure if this is an issue with CC.NET or with PSEXEC (or me of course). Anybody got any ideas? I'm posting to the CC.NET forums as well. I'm using the latest and greatest of PSExec and 1.4.4 of CC.NET. Thx, Joel

• Is there a WPF "WrapGrid" control available or an easy way to create one?

  - by Jason Coyne

  Essentially I want a wrapPanel, but I would like items to snap to a grid rather than be pressed up to the left, so I can get a nice uniform looking grid, that automatically consumes available space. WrapPanel handles the resize part. WPF.Contrib.AutoGrid handles a nice automatic grid. Anyone got a control that combines them? My use case is I have a series of somewhat irregularly shaped controls. I would like them to appear in nice columns so the wrap panel should snap to the next "tabstop" when placing a control

• object of type 'closure' is not subsettable - contradiction?

  - by Alex

  I'm writing a function to produce time series plots of stock prices. However, I'm getting the following error "Error in df[, 7] : object of type 'closure' is not subsettable" Here's an example of the function: plot.prices <- function(df) { require(ggplot2) g <- ggplot(df, aes(x= as.Date(Date, format= "%Y-%m-%d"), y= df[, 7])) + geom_point(size=1) # ... code not shown... g } And example data: spy <- read.csv(file= 'http://ichart.finance.yahoo.com/table.csv?s=SPY&d=11&e=1&f=2012&g=d&a=0&b=29&c=1993&ignore=.csv', header= T) plot.prices(spy) # produces error ggplot(spy, aes(x= as.Date(Date, format= "%Y-%m-%d"), y= spy[, 7])) + geom_point(size=1) ## does not produce error As you can see, the code is identical. I get an error if the call to ggplot() is INSIDE the function but not if the call to ggplot() is OUTSIDE the function. Anyone have any idea why the seeming contradiction?

• Understanding what SPARQL is

  - by user73119

  This is a terribly beginner series of questions, but after reading through a good 30 SPARQL tutorials I can't seem to wrap my head around what SPARQL is or how to begin using it. Is it executed on the client side? Is microsoft somehow going to be able to mess this up? Can you use a common relational database (SQL)? Are there particular resources you recommend over others for learning? Do you feel it is premature to begin investing myself in this? Best way to get set up and running to start tinkering? The RDFA examples I have seen are very inspiring. I am currently a big proponent of using microformats but would really like to take it further. I currently develop in PHP, but have only found a Java library.

• How can I find the song position of a song being played with XACT?

  - by DJ SymBiotiX

  So I'm making a game in XNA and I need to use XACT for my songs (rather than media player). I need to use XACT because each song will have multiple layers that combine when played at the same time (bass, lead, drums) etc. I cant use the media player because the media player can only play one song at a time. Anyways, so lets say I have a song playing with XACT in my project with the following code public SongController() { audioEngine = new AudioEngine(@"Content\Song1\Song1.xgs"); waveBank = new WaveBank(audioEngine, @"Content\Song1\Layers.xwb"); soundBank = new SoundBank(audioEngine, @"Content\Song1\SongLayers.xsb"); songTime = new PlayTime(); Vox = soundBank.GetCue("Vox"); BG = soundBank.GetCue("BG"); Bass = soundBank.GetCue("Bass"); Lead = soundBank.GetCue("Lead"); Other = soundBank.GetCue("Other"); Vox.SetVariable("CueVolume", 100.0f); BG.SetVariable("CueVolume", 100.0f); Bass.SetVariable("CueVolume", 100.0f); Lead.SetVariable("CueVolume", 100.0f); Other.SetVariable("CueVolume", 100.0f); _bassVol = 100.0f; _voxVol = 100.0f; _leadVol = 100.0f; _otherVol = 100.0f; Vox.Play(); BG.Play(); Bass.Play(); Lead.Play(); Other.Play(); } So when I look at the variables in Vox, or BG (they are Cue's btw) I cant seem to find any play position in them. So I guess the question is: Is there a variable I can query to find that data, or do I need to make my own class that starts counting up from the time I start the song? Thanks

• Python progression path - From apprentice to guru

  - by Morlock

  Hi all, I've been learning, working, and playing with Python for a year and a half now. As a biologist slowly making the turn to bio-informatics, this language has been a the very core of all the major contributions I have made in the lab. (bash and R scripts have helped some too. My C++ capabilities are very not functional yet). I more or less fell in love with the way Python permits me to express beautiful solutions and also with the semantics of the language that allows such a natural flow from thoughts to workable code. What I would like to know from you is your answer to a kind of question I have seldom seen in this or other forums. Let me sum up what I do NOT want to ask first ;) I don't want to know how to QUICKLY learn Python Nor do I want to find out the best way to get acquainted with the language Finally, I don't want to know a 'one trick that does it all' approach. What I do want to know your opinion about, is: What are the steps YOU would recommend to a Python journeyman, from apprenticeship to guru status (feel free to stop wherever your expertise dictates it), in order that one IMPROVES CONSTANTLY, becoming a better and better Python coder, one step at a time. The kind of answers I would enjoy (but feel free to surprise the readership :P ), is formatted more or less like this: Read this (eg: python tutorial), pay attention to that kind of details Code for so manytime/problems/lines of code Then, read this (eg: this or that book), but this time, pay attention to this Tackle a few real-life problems Then, proceed to reading Y. Be sure to grasp these concepts Code for X time Come back to such and such basics or move further to... (you get the point :) This process depicts an iterative Learn/Code cycle, and I really care about knowing your opinion on what exactly one should pay attention to, at various stages, in order to progress CONSTANTLY (with due efforts, of course). If you come from a specific field of expertise, discuss the path you see as appropriate in this field. Thanks a lot for sharing your opinions and good Python coding!

• Why is Selenium RC so slow?

  - by Pete

  Hi. For some time I have been investigating Selenium RC in order to do functional testing of my web application. I have now found a test strategy that is so effective, that I do not want to move away from Selenium RC (after spending weeks trying to figure out a good way to validate ASP.NET validation controls). But now that my Selenium RC adventure is moving from a POC to be something that I actually use, I'm running into a problem. It is insanely slow. Executing a single test that loads a page, fills in some fields, and clicks a button takes in the magnitude of seconds to execute. When it is executing, I can easily see each individual field being filled out one at a time. Using Selenium IDE in Firefox is not that slow. I found this page, that clearly specifies that Selenium RC is slow http://selenium-grid.seleniumhq.org/how_it_works.html But why is that? Is it because the browser is polling the selenium server? If so, can this polling interval not be modified? Or is there another reason. I am not accustomed to a remote call taking a humanly noticable amount of time to execute. It is horrible that executing a few tests should take so long. I can execute my entire presentation (MVP), business, and database layer test suite (500+ tests) way quicker than it takes to run 10 tests for a single web page.

• UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

  - by Jesse Grosjean

  Edit Reposting... I accidentally marked my previous question as "commuity wiki" and didn't realize that answers to wiki posts don't generate reputation. I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the UIAlertView the cut/copy/paste popup menu will show in UITextField that's been added to the UIAlertView. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again next time I show the UIAlertView (new instance) unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

  We are running visual studio 2008 (with the service pack) and having troubles when we are debugging an asp classic website. We can attach to the w3p process and debug just fine. breakpoints work, we can view variable values. The difficulty arises when it comes time to detach or stop the debugger. Every time we take either approach (detach or stop the debugger) we get a series of crashes from Visual studio. Has anyone seen anything like this? Any suggestions on what to look at?

• NSDate dateFromString, how to parse 'around' UTC, GMT and User locale?

  - by RickiG

  Hi I parse some values from an xml file. There is a @"25-12-2010'T'23:40:00"string with the time and date and there is a string with the GMT offset like this @"+0200". So the above time is the 25. of December 23:40:00 in timeZone +0200 GMT. (or 21:40 UTC) I have lots of these dates with different GMT offsets. I have to display these dates as they are, i.e. They must not be changed to fit the locale of the user. So if time 1: is 22:45 +0500 then that is what I must show the user, even if the user is in a different timezone. I have all sorts of trouble with displaying, calculating and parsing these strings. If I use a dateFormatter and dateFromString the user specific GMT info will be included in the resulting NSDate meaning the above will be saved as 23:40:00 +0100 GMT because that is my phones setting and maybe 23:40:00 -0400 on a user from new New York's phone. When I subsequently do subtraction, addition and comparisons between these dates I have to keep the GMT offset around and everything gets worse if the phone switches locale settings, from when the date was parsed to when the date is displayed... Is there a way for me to extract this date from the string as UTC, then save it as an interval instead of an actual (timezone dependent) date. I know that is how dates are always saved internally. But I can't figure out how to do it with the separate GMT string and taking into account the users locale. Cheers

• POCO Best Practice

  All, I have a series of domain objects (project is NHibernate based). Currently as per 'good practice' they define only the business objects, comprising properties and methods specific to each objects function within the domain. However one of the objects has a requirement to send an SMTP message. I have a simple SMTP client class defined in a separate 'Utilities' assembly. In order to use this mail client from within the POCO, I would need to hold a reference to the utilities assembly in the domain. My query is this... Is it a departure from best practice to hold such a reference in a POCO, for the purpose of gaining necessary business functionality. Kind Regards Paul J.
