• what's the right way to use scala.io.Source?

  - by woods

  In many examples, it is described that you can use scala.io.Source to read a whole file like this: val str = scala.io.Source.fromFile("test.txt").mkString() But closing the underlying stream is not mentioned. Why does Scala not provide a convenient way to do that such as with clause in Python? It looks useful but not difficult. Is there any other better way to do that safely in Scala, i means to read a whole file?

• Why is Google Charts not showing the right data for me? Are the axis messed up?

  - by alex

However, the axis are messed up! And it seems like I can't see the ups and downs of my line graph. WHy? I don't get what's wrong. I just want to plot the simple stuff on a line chart. Just those data points. Nothing more, nothing less!

• What is the right way to initialize a constant in Ruby?

  - by zbrimhall

  I have a simple class that defines some constants, e.g.: module Foo class Bar BAZ = "bof" ... Everything is puppies and rainbows until I tell Rake to run all my Test::Unit tests. When it does, I get warnings: bar.rb:3: warning: already initialized constant BAZ My habit has been to avoid these warnings by making the constant initialization conditional, e.g.: ... BAZ = "bof" unless const_defined? :BAZ ... This seems to solve the problem, but it is a little tedious, and I don't ever see anyone else initializing constants this way. This makes me think I might be Doing It Wrong. Is there a better way to initialize constants that won't generate warnings?

  The buttons I have added to the rows still post back even if I specifiy not to do so in the onclick method of the button (onclick=' return false;'). I supose its the grid doing the post back? I am tring to prevent the postback and show my own custom popup forms. gridComplete: function(){ var ids = $('#jqGridControl1').jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var rowid = ids[i]; de = "<input type='image' title='Delete this record.' src='../images/icn_delete.gif' onclick=' return false;' style='border-width:0px;'/>"; ee = "<input type='image' title='Edit this record.' src='../images/icn_edit.gif' onclick=' return false;' style='border-width:0px;' />"; ve = "<input type='image' title='View related information.' src='../images/house.gif' onclick='return false;' style='border-width:0px;' />"; pe = "<input type='image' title='Print' src='../images/icn_printer.gif' onclick=' return false;' style='border-width:0px;' />"; je = "<input type='image' title='Appointment' src='../images/icn_journal.gif' onclick=' return false;' style='border-width:0px;' />"; se = "<input type='image' title='Select' src='../images/icn_select.gif' onclick=' return false;' style='border-width:0px;' />"; jQuery('#jqGridControl1').jqGrid('setRowData',ids[i],{act:de+ee+ve+pe+je+se}); }

• Flex chart not displaying right values along x axis.

  - by Shah Al

  I don't know of any better way to ask this question. If the below code is run (i know the cData sections are not visible in the preview, something causes it to be ignored). The result does not represent the data correctly. 1. Flex ignores missing date 24 aug for DECKER. 2. It wrongly associates 42.77 to 23-Aug instead of 24-AUG. Is there a way in flex, where the x-axis is a union of all available points ? The below code is entirely from : Adobe website link I have only commented 2 data points. //{date:"23-Aug-05", close:45.74}, and //{date:"24-Aug-05", close:150.71}, <?xml version="1.0"?> [Bindable] public var SMITH:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:41.87}, //{date:"23-Aug-05", close:45.74}, {date:"24-Aug-05", close:42.77}, {date:"25-Aug-05", close:48.06}, ]); [Bindable] public var DECKER:ArrayCollection = new ArrayCollection([ {date:"22-Aug-05", close:157.59}, {date:"23-Aug-05", close:160.3}, //{date:"24-Aug-05", close:150.71}, {date:"25-Aug-05", close:156.88}, ]); [Bindable] public var deckerColor:Number = 0x224488; [Bindable] public var smithColor:Number = 0x884422; ]] <mx:horizontalAxisRenderers> <mx:AxisRenderer placement="bottom" axis="{h1}"/> </mx:horizontalAxisRenderers> <mx:verticalAxisRenderers> <mx:AxisRenderer placement="left" axis="{v1}"> <mx:axisStroke>{h1Stroke}</mx:axisStroke> </mx:AxisRenderer> <mx:AxisRenderer placement="left" axis="{v2}"> <mx:axisStroke>{h2Stroke}</mx:axisStroke> </mx:AxisRenderer> </mx:verticalAxisRenderers> <mx:series> <mx:ColumnSeries id="cs1" horizontalAxis="{h1}" dataProvider="{SMITH}" yField="close" displayName="SMITH" > <mx:fill> <mx:SolidColor color="{smithColor}"/> </mx:fill> <mx:verticalAxis> <mx:LinearAxis id="v1" minimum="40" maximum="50"/> </mx:verticalAxis> </mx:ColumnSeries> <mx:LineSeries id="cs2" horizontalAxis="{h1}" dataProvider="{DECKER}" yField="close" displayName="DECKER" > <mx:verticalAxis> <mx:LinearAxis id="v2" minimum="150" maximum="170"/> </mx:verticalAxis> <mx:lineStroke> <mx:Stroke color="{deckerColor}" weight="4" alpha="1" /> </mx:lineStroke> </mx:LineSeries> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/>

• What is the best keyboard/mouse for ergonomics or to prevent wrist pain?

  - by Steve Duitsman

  I have had pain in my wrists in the past, and as someone who types all day, I was wondering what are some keyboards or mice that have helped for this sort of pain. Update: Many answers have recommended examining chairs/desks for ergonomics. As someone who isn't able to work from home and therefore doesn't have a lot of control over this; is ordering my own chair/desk (whether my employer or I purchase it) a solution that's really realistic?

• iPhone UIView Animation Disables UIButton Subview

  - by bensnider

  So I've got a problem with buttons and animations. Basically, I'm animating a view using the UIView animations while also trying to listen for taps on the button inside the view. The view is just as large as the button, and the view is actually a subclass of UIImageView with an image below the button. The view is a subview of a container view placed in Interface Builder with user interaction enabled and clipping enabled. All the animation and button handling is done in this UIImageView subclass, while the startFloating message is sent from a separate class as needed. If I do no animation, the buttonTapped: message gets sent correctly, but during the animation it does not get sent. I've also tried implementing the touchesEnded method, and the same behavior occurs. UIImageView subclass init (I have the button filled with a color so I can see the frame gets set properly, which it does): - (id)initWithImage:(UIImage *)image { self = [super initWithImage:image]; if (self != nil) { // ...stuffs UIButton *tapBtn = [UIButton buttonWithType:UIButtonTypeCustom]; tapBtn.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height); [tapBtn addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; tapBtn.backgroundColor = [UIColor cyanColor]; [self addSubview:tapBtn]; self.userInteractionEnabled = YES; } return self; } Animation method that starts the animation (if I don't call this the button works correctly): - (void)startFloating { [UIView beginAnimations:@"floating" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:10.0f]; self.frame = CGRectMake(self.frame.origin.x, -self.frame.size.height, self.frame.size.width, self.frame.size.height); [UIView commitAnimations]; } So, to be clear: Using the UIView animation effectively disables the button. Disabling the animation causes the button to work. The button is correctly sized and positioned on screen, and moves along with the view correctly.

• MS-Access: What could cause one form with a join query to load right and another not?

  - by Daniel Straight

  Form1 Form1 is bound to Table1. Table1 has an ID field. Form2 Form2 is bound to Table2 joined to Table1 on Table2.Table1_ID=Table1.ID Here is the SQL (generated by Access): SELECT Table2.*, Table1.[FirstFieldINeed], Table1.[SecondFieldINeed], Table1.[ThirdFieldINeed] FROM Table1 INNER JOIN Table2 ON Table1.ID = Table2.[Table1_ID]; Form2 is opened with this code in Form1: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form2", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form1", acSaveYes And when loaded runs: Me.[Table1_ID] = Me.OpenArgs When Form2 is loaded, fields bound to columns from Table1 show up correctly. Form3 Form3 is bound to Table3 joined to Table2 on Table3.Table2_ID=Table2.ID Here is the SQL (generated by Access): SELECT Table3.*, Table2.[FirstFieldINeed], Table2.[SecondFieldINeed] FROM Table2 INNER JOIN Table3 ON Table2.ID = Table3.[Table2_ID]; Form3 is opened with this code in Form2: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form3", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form2", acSaveYes And when loaded runs: Me.[Table2_ID] = Me.OpenArgs When Form3 is loaded, fields bound to columns from Table2 do not show up correctly. WHY? UPDATES I tried making the join query into a separate query and using that as my record source, but it made no difference at all. If I go to the query for Form3 and view it in datasheet view, I can see that the information that should be pulled into the form is there. It just isn't showing up on the form.

• MVC2 Annotations dll not found by VS2008 compiler, how do I make it look in the right place?

  - by Paul Connolly

  I have VS2008 SP1 running with .NET 3.5 SP1 I have MVC2 running (with MVC1 uninstalled) All works ok except when I call the System.Components.DatAnnotations.dll, then the compiler complains of not being able to find it. Message is: Could not load file or assembly 'System.ComponentModel.DataAnnotations, Version=99.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I tried repairing and reinstalling SP1 of both VS and .Net framework. I also tried referencing the assembly by browsing to it in the Reference assemblies in Programs directory. I have tried out most of the Google search result forum results but to no avail, I think it may be something simple which I have over looked. Any ideas?

• What's the right way to calculate derived data in a Flex AdvancedDataGrid using summaries?

  - by Chris R

  Here's the gist of the problem: I have a set of rows of data with (say) field1 to field4 in them. I'm using a GroupingCollection to group on field1 and field2. So, I have something like this: f1.1 f2.1 f3.1 f4.1 f3.2 f4.2 f2.2 f3.3 f4.3 f3.4 f4.4 f3.5 f4.5 f1.2 f2.1 f3.6 f4.6 f2.2 f3.7 f4.7 f3.8 f4.8 f3.9 f4.9 (or at least, I hope that's clear enough) I need to calculate some derived values for each leaf row, for example f3, that is the ratio of f3 to the average of all f3 in that particular part of the tree. So, for f3.7 I need to calculate f3.7 / avg(f3.7..f3.9) and fill that into the f3_index property on the row, displaying that in lieu of f3 itself. So, basically, what it looks like I have to do is add source field values in the summarizeFunction implementation. It seems to me that there must be a better way of doing this. Is there?

• PHP, We have sessions, and cookies....I love cookies, but they are blowing my mind right now.

  - by Matt

  I am not sure how to go about accessing the variable I need to set on a cookie... I was thinking about using the $_POST global but I dont know how based on my design if it will work. I am using a master page type design seperating index.php from my function includes and database information and individual pages (that will be returned to an include in index.php based on a $_GET) Okay so back to my question. What is the most efficient way to set a cookie on a design that has a main page that everything will branch from. How would I pull the value. Is $_POST a good enough way to go about it? Also...by saying it must be the first thing sent...does that mean I cannot run any serverside scripts before that? I could definately utilize a login query I think but I dont want to write code just to be dissapointed based on my lack of time and knowledge. I did search for answers...I know this most likely feels like a generic question that could be answered in a difference place...but I know I will get an accurate and professional answer here...so I dont want to bet on the half answers I found otherwise. Of course I will sanitize everything and not store any sensitive information (passwords,address,phone,or anything really for that matter besides some kind of session ID and the username) If this is confusing I am sorry but I am on a gov computer...and they lock these tighter than ft knox...so getting my code on here will be a chore until I get back to my room. Thanks, Matt

  Hi there, Bit of a newbie when it comes to android, only been working on it properly for a few days but even after all the searching I've done im stumped and nobody seems to know how to help me.

• SVM in OpenCV: Visual Studio 2008 reported error wrongly (or is it right?)

  - by Risa

  I'm using MS Visual Studio 2008, OpenCV, C++ and SVM for a OCR-related project. At least I can run the code until yesterday, when I open the project to continue working, VS reported this error: error C2664: 'bool CvSVM::train(const CvMat *,const CvMat *,const CvMat *,const CvMat *,CvSVMParams)' : cannot convert parameter 1 from 'cv::Mat' to 'const CvMat *' It didn't happen before and I haven't changed any code relating to it (I only changed the parameters for the kernel). The code got error is: Mat curTrainData, curTrainLabel; CvSVM svm; . . . svm.train(curTrainData, curTrainLabel, Mat(), Mat(), params); If I hover on the code, I still got this tip: image. Which means my syntax isn't wrong. So why do VS bother to report such an error?

• Asp.Net application/web service not working on Vista/IIS7: access right problem?

  - by Achim

  I have an .Net 3.5 based web service running at http://localhost/serivce.svc/. Then I have a Asp.Net application running at http://localhost/myApp. In Application_Load my App reads some XML configuration from the web service. That works fine on my machine, but: On Vista with IIS7 the request to the web services fails. The web service can be accessed via the browser without any problem. I configured the app pool of my App to run as admin. I added the admin to the IIS_USRS group, but it still cannot access the web service. impersonate=true/false seems not to make a difference.

• UIButtons work when rotated right, but not when rotated left. Huh?

  - by Ben Collins

  I have a view that is added to the current view when the device is rotated to a LandscapeLeft or LandscapeRight orientation. This view has 4 buttons on it that are all connected to outlets and each have the "touch up inside" event hooked up to the same action. If rotated to a LandscapeLeft orientation, I transform my added view to rotate -90 degrees, and everything works fine. If rotated to a LandscapeRight orientation, I transform the added view to rotate 90 degrees, and the buttons don't work! Highlighting doesn't happen, and the action isn't called. I am at a bit of a loss as to why this might be. Any ideas?

• Problem with DataTrigger binding - setters are not being called

  - by aoven

  I have a Command bound to a Button in XAML. When executed, the command changes a property value on the underlying DataContext. I would like the button's Content to reflect the new value of the property. This works*: <Button Command="{x:Static Member=local:MyCommands.TestCommand}" Content="{Binding Path=TestProperty, Mode=OneWay}" /> But this doesn't: <Button Command="{x:Static Member=local:MyCommands.TestCommand}"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="True"> <DataTrigger.Setters> <Setter Property="Content" Value="Yes"/> </DataTrigger.Setters> </DataTrigger> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="False"> <DataTrigger.Setters> <Setter Property="Content" Value="No"/> </DataTrigger.Setters> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Why is that? * By "works" I mean the Content gets updated whenever I click the button.

• What is the right way to make a new XMLHttpRequest from an RJS response in Ruby on Rails?

  - by Yuri Baranov

  I'm trying to come closer to a solution for the problem of my previous question. The scheme I would like to try is following: User requests an action from RoR controller. Action makes some database queries, makes some calculations, sets some session variable(s) and returns some RJS code as the response. This code could either update a progress bar and make another ajax request. display the final result (e.g. a chart grahic) if all the processing is finished The browser evaluates the javascript representation of the RJS. It may make another (recursive? Is recursion allowed at all?) request, or just display the result for the user. So, my question this time is: how can I embed a XMLHttpRequest call into rjs code properly? Some things I'd like to know are: Should I create a new thread to avoid stack overflow. What rails helpers (if any) should I use? Have anybody ever done something similar before on Rails or with other frameworks? Is my idea sane?

• How to change one Button background in a gridview? -- Android

  - by Tstop Studios

  I have a GridView with 16 ImageView buttons. My program makes a random number and when the user clicks a button in the gridview, i want it to take the random number (0-15) and set the background of the tile with the same position as the random number (0-15) to a different image. How can I just change one of the buttons background? Here's my code so far: public class ButtonHider extends Activity { Random random = new Random(); int pos; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.button_hider); pos = random.nextInt(15); GridView gridview = (GridView) findViewById(R.id.gvBH); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position, long id) { pos = random.nextInt(16); if (position == pos) { Toast.makeText(ButtonHider.this, "Found Me!", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(ButtonHider.this, "Try Again!!", Toast.LENGTH_SHORT).show(); } } }); } public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return 16; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some // attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(100, 100)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(15, 15, 15, 15); } else { imageView = (ImageView) convertView; } imageView.setImageResource(R.drawable.bh_b); return imageView; } } }

• WPF: Once I set a property in code, it ignores XAML binding forever more... how do I prevent that?

  - by Timothy Khouri

  I have a button that has a datatrigger that is used to disable the button if a certain property is not set to true: <Button Name="ExtendButton" Click="ExtendButton_Click" Margin="0,0,0,8"> <Button.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding IsConnected}" Value="False"> <Setter Property="Button.IsEnabled" Value="False" /> </DataTrigger> </Style.Triggers> </Style> </Button.Style> That's some very simple binding, and it works perfectly. I can set "IsConnected" true and false and true and false and true and false, and I love to see my button just auto-magically become disabled, then enabled, etc. etc. However, in my Button_Click event... I want to: Disable the button (by using ExtendButton.IsEnabled = false;) Run some asynchronous code (that hits a server... takes about 1 second). Re-enable the button (by using ExtendButton.IsEnabled = true;) The problem is, the very instant that I manually set IsEnabled to either true or false... my XAML binding will never fire again. This makes me very sad :( I wish that IsEnabled was tri-state... and that true meant true, false meant false and null meant inherit. But that is not the case, so what do I do?
