• NSTableView - Trying to fit exactly 9 rows

  - by Justin808

  Hi, I'm trying to size the rows of a NSTableView to exactly 9 rows fit. I've tried [menuTableView setRowHeight:floor(menuRect.size.height / 9)]; and I've tried [menuTableView setRowHeight:(menuRect.size.height / 9)]; and [menuTableView setRowHeight:ceil(menuRect.size.height / 9)]; but all of them have the same issue, if I've selected row 0 then row 9 is clipped at the bottom and if I select row 9 then row 0 is clipped at the top. How can I set up a NSTableView to show 9 full rows so no matter what there is never a partial row visible? Thanks, edit: Yes menuRect is the frame for the menuTableView

• Split string into smaller part with constrain [PHP RegEx HTML]

  - by Sadi

  Hello, I need to split long string into a array with following constrains: Each part will have a limited number of character (e.g. not more than 8000 character) Each part can contain multiple sentences (delimited by . [full stop]) but never a partial sentences. Except if the last part of the string (as last part may not have any full stop. The string may contain HTML tags. But the tag can not be divided as ( to ). That means HTML tag should be intact. But starting tag and ending tag can be stay on different segment/chunk. I think regular expression with preg_split can do it. Would please help me with the proper RegEx. Thank you Sadi

• Creating new table entry when updating another entry of another table - Ruby on Rails

  - by Michaël

  Hi, I have written this code in my "show" view of estimates and I want that, when submitting (update), it creates a new repairs (Repair.new(???)) with some parameters. I don't know where to write the "new repairs" code, in this view or the controller (in update part). I need that the Repair is created one time, not each time the @estimate is updated. <% form_for @estimate, :url => {:controller => "estimates", :action => "update"} do |f| %> <%= f.error_messages %> <select id="estimate_accept" name="estimate[accept]"> <option value="1" selected="selected">accept</option> <option value="2">refuse</option> </select> <%= f.submit "Update" %> <% end %> Thank you for your help, I hope my explanations are clear!

• How to use form_tag to update params

  - by Tryskele

  I have been struggling with a problem in Rails for a couple of days and still could not find the solution. Could you help me with that? Problem: I have a search box that puts a :search_string entry in the params structure. I use a form_tag for that and it works fine. <% form_tag :controller=> 'items', :action => 'find' do %> <%= text_field_tag :search_string, params[:search_string] %> <% end %> The problem is when I want to add and update other params key-value (in another view), for instance :start_date, to filter the search_string result. Here is the code snipped that I use in the view: <% form_tag :controller=> "items", :action => "find", :params => params do %> <%= hidden_field_tag :date_start, '2010-04-01' %> <%= submit_tag 'April' %> <% end %> <% form_tag :controller=> "items", :action => "find", :params => params do %> <%= hidden_field_tag :date_start, '2010-03-01' %> <%= submit_tag 'March' %> <% end %> When I first click on "April" submit button, then the params is correctly passed to the controller (i.e. there is a params[:start_date]='April'). However when I try to click "March" button afterwards, the params[:start_date] is not updated. I definitely think this is a stupid newbie mistake, but I cannot figure out how to properly use the form_tag. Could you tell me if I am doing something work? Otherwise, could you advise me which is the best way to update the params using form_tag's ? Thank you very much in advance. Miquel

• How to customize the printing while using Window.print ?

  - by Holicreature

  i want to print a invoice and i use a print.css by media=print and when i change the current stylesheet to print.css i could able to view what i should be printing without the titles and content left aligned. But still while i'm printing there is space in the top and left and its taking up whole a4 sheet and also the whole width of the page.. But i've defined a body width of just 550 px. While i view to print preview, it takes the whole width instead of taking up 1/3 of the width.. My print.css is body { width:550px; height:450px; color:#000000; margin:0; padding:0; word-spacing:1.1pt; font-family : "Times New Roman", Times, serif; font-size : 10px; text-align:left; } a { visibility :hidden; display : none; } input{ display : none; } table { margin: 1px; text-align:left; } #list,#head,#cont,#fotter,#oth,#links,#name,li,ul,ol { display : none; } I'm printing through browser using window.print, so is there any special configuration i need to do...?

• MVC and jQuery data retrieval.

  - by user337542

  Hello, I am using mvc and jQuery and I am trying to display someone's profile with some additional institutions that the person belongs to. I am new to this but I've done something like this in ProfileControler: public ActionResult Institutions(int id) { var inst = fr.getInstitutions(id); return Json(inst); } getInstitutions(id) returns Institution objects(with Name, City, Post Code etc.) Then in a certain View I am trying to get the data with jQuery and display them as follows: $(document).ready(function () { $.post("/Profile/Institutions", { id: <%= Model.Profile.userProfileID %> }, function (data) { $.each(data, function () { var new_div = $("<div>"); var new_label = $("<label>"); new_label.html(this.City); var new_input_b = $("<input>"); new_input_b.attr("type", "button"); new_div.append(new_label); new_div.append(new_input_b); $("#institutions").append(new_div); }); }); }); $("#institutions") is a div where i want to display all of the results. .post works correct for sure because certain institutions are retrieved from database, and passed to the view as Json result. But then I am affraid it wont itterate with .each. Any help, coments or pointing in some direction would be much appriciated

• Need help with many-to-many relationships....

  - by yuudachi

  I have a student and faculty table. The primary key for student is studendID (SID) and faculty's primary key is facultyID, naturally. Student has an advisor column and a requested advisor column, which are foreign key to faculty. That's simple enough, right? However, now I have to throw in dates. I want to be able to view who their advisor was for a certain quarter (such as 2009 Winter) and who they had requested. The result will be a table like this: Year | Term | SID | Current | Requested ------------------------------------------------ 2009 | Winter | 860123456 | 1 | NULL 2009 | Winter | 860445566 | 3 | NULL 2009 | Winter | 860369147 | 5 | 1 And then if I feel like it, I could also go ahead and view a different year and a different term. I am not sure how these new table(s) will look like. Will there be a year table with three columns that are Fall, Spring and Winter? And what will the Fall, Spring, Winter table have? I am new to the art of tables, so this is baffling me... Also, I feel I should clarify how the site works so far now. Admin can approve student requests, and what happens is that the student's current advisor gets overwritten with their request. However, I think I should not do that anymore, right?

• Android -- SDK/IDE Layout Bug (w/Custom Layouts)??

  - by borg17of20

  Hello all, Can someone tell me if this is a bug in the SDK/IDE: Any custom or extended layout I add to my layout XML causes the IDE to ignore the fact that there are any child views of that layout (they just disappear from the outline view/window), thus making them uneditable via the properties view/window. (I need to extend a layout to make onSetAlpha() public) FYI: I'm developing for Android 1.5 and up, using all the latest plug-ins/updates in Eclipse Here is a simple example of a layout XML and the extended Layout that causes this error. [Extended Layout] package com.test; public class CustomLinearLayout extends LinearLayout { public CustomLinearLayout(Context context, AttributeSet attrs) { super(context, attrs); } public CustomLinearLayout(Context context) { super(context); } } [Simple layout XML] <?xml version="1.0" encoding="utf-8"?> <com.test.CustomLinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> </com.test.CustomLinearLayout> ImageView01 is not visible or editable in the properties or outline views/windows.

• iphone - grouping UIImageViews x blocking elements

  - by Mike

  I have to rotate several UIImageViews around a specific center. To accomplish this I am using the famous trick of putting these views as subviews of a larger one and rotating that one. The problem is that these subviews have to detect touches, because each one has buttons on it. The hierarchy is like this LARGE_VIEW | |_____ imageView1 | |_________ button1 | |_________ button2 | |_________ button3 | |_____ imageView2 |_________ button4 |_________ button5 |_________ button6 etc So, to make buttons respond to tap, I had to make this; [LARGE_VIEW setUserInteractionEnabled:YES]; [imageView1 setUserInteractionEnabled:YES]; [imageView2 setUserInteractionEnabled:YES]; ImageView1 and 2 are two vertical rows of buttons on each side of the screen. The problem is that there's another view below LARGE_VIEW and this view is not receiving the taps, because LARGE_VIEW is intercepting them first. I don't need LARGE_VIEW to detect any taps except on the two areas where imageView 1 and 2 are. LARGE_VIEW must let pass taps on the area defined by this rect (52, 0, 768-2*52, 1024). ImageView1 and 2 have this size: 52 pixels wide and 1024 pixels high (iPad). ImageView1's rect is: (0, 0, 52, 1024) and ImageView2's rect is: (768-52, 0, 52, 1024) LARGE_VIEW must let pass taps on the area defined by this rect (52, 0, 768-2*52, 1024). How to solve that? I need LARGE_VIEW detect taps on each rect defined on my previous paragraph and pass these taps to its subviews and just let pass taps outside these rects to the app, so other views BELOW, can detect taps too. thanks.

• Creating a RESTful service in CakePHP

  - by NathanGaskin

  I'm attempting to create a RESTful service in CakePHP but I've hit a bit of a brick wall. I've enabled the default RESTful routing using Router::mapResources('users') and Router::parseExtensions(). This works well if I make a GET request, and returns some nicely formatted XML. So far so good. The problem is if I want to make a POST or PUT request. CakePHP doesn't seem to be able to read the data from the request. At the moment my add(), edit() and delete() actions don't contain any logic, they're simply setting $this-data to the view. I'm testing with the following cURL command: curl -v -d "<user><username>blahblah</username><password>blahblah</password>" http://localhost/users.xml --header 'content-type: text/xml' Which only returns a 404 header. If I remove the --header parameter then it returns the view but no data is set. It feels like I'm missing something obvious here. Any ideas?

• ASP.NET MVC - Wrong redirecting, how to debug?

  - by Xorty

  I am stuck with redirecting problem in ASP.NET MVC project. I have mapped tables via LINQtoSQL and each has unique ID as primary key. I am implementing functionallity of 'CREATE'. Basically, after new value is added into SQL table (which means I pressed Save button), I want to be redirected to Details of this freshly added item. Here's little code how I am doing it : [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Create(Item item) { .... return RedirectToAction("Details", new { id = item.ItemID }); Trouble is, I am never redirected to Details view (I have Details.aspx view for items). When I check CallHierarchy in Visual Studio (2010 pro) the hierarchy is indeed little strange, like this : RedirectToAction(string,object) Calls To 'RedirectToAction' Create Calls To Create (no results) Calls From Create (methods of created instance. From there I'll get back to 'RedirectToAction' and to 'Calls to Create' and 'Calls From Create' etc. etc. - loop Edit Calls From 'RedirectToAction' Not supported I am looking for some tools or more specifically 'know how' (since VS probably has some tools) to debug this kind of situations. PS: rooting is default :"{controller}/{action}/{id}", Thanks

• Qt/C++ - confused about caller/callee, object ownership

  - by Isabel

  I am creating a GUI to manipulate a robot arm. The location of the arm can be described by 6 floats (describing the positions of the various arm joints. The interface consists of a QGraphicsView with a diagram of the arm (which can be clicked to change the arm position - adjusting the 6 floats). The interface also has 6 lineEdit boxes, to also adjust those values separately. When the graphics view is clicked, and when the line edit boxes are changed, I'd like the line edit boxes / graphics view to stay in synchronisation. This brings me to confusion about how to store the 6 floats, and trigger events when they're updated. My current idea is this: The robot arm's location should be represented by a class, RobotArmLocation. Objects of this class then have methods such as obj.ShoulderRotation() and obj.SetShoulderRotation(). The MainWindow has a single instance of RobotArmLocation. Next is the bit I'm more confused about, how to join everything up. I am thinking: The MainWindow has a ArmLocationChanged slot. This is signalled whenever the location object is changed. The diagram class will have a SetRobotArmLocation(RobotArmLocation &loc). When the diagram is changed, it's free to change the location object, and fire a signal to the ArmLocationChanged slot. Likewise, changing any of the text boxes will fire a signal to that ArmLocationChanged slot. The slot then has code to synchronise all the elements. This kind of seems like a mess to me, does anyone have any other suggestions? I've also thought of the following, does it have any merrit? The RobotArmLocation class has a ValueChanged slot, the diagram and textboxes can use that directly, and bypass the MainWindow directly (seems cleaner?) thanks for any wisdom!

• Dealing with rapid tapping on Buttons

  - by Eric Burke

  I have a Button with an OnClickListener. For illustrative purposes, consider a button that shows a modal dialog: public class SomeActivity ... { protected void onCreate(Bundle state) { super.onCreate(state); findViewById(R.id.ok_button).setOnClickListener( new View.OnClickListener() { public void onClick(View v) { // This should block input new AlertDialog.Builder(SomeActivity.this) .setCancelable(true) .show(); } }); } Under normal usage, the alert dialog appears and blocks further input. Users must dismiss the dialog before they can tap the button again. But sometimes the button's OnClickListener is called twice before the dialog appears. You can duplicate this fairly easily by tapping really fast on the button. I generally have to try several times before it happens, but sooner or later I'll trigger multiple onClick(...) calls before the dialog blocks input. I see this behavior in Android 2.1 on the Motorola Droid phone. We've received 4 crash reports in the Market, indicating this occasionally happens to people. Depending on what our OnClickListeners do, this causes all sorts of havoc. How can we guarantee that blocking dialogs actually block input after the first tap?

• ndarray field names for both row and column?

  - by Graham Mitchell

  I'm a computer science teacher trying to create a little gradebook for myself using NumPy. But I think it would make my code easier to write if I could create an ndarray that uses field names for both the rows and columns. Here's what I've got so far: import numpy as np num_stud = 23 num_assign = 2 grades = np.zeros(num_stud, dtype=[('assign 1','i2'), ('assign 2','i2')]) #etc gv = grades.view(dtype='i2').reshape(num_stud,num_assign) So, if my first student gets a 97 on 'assign 1', I can write either of: grades[0]['assign 1'] = 97 gv[0][0] = 97 Also, I can do the following: np.mean( grades['assign 1'] ) # class average for assignment 1 np.sum( gv[0] ) # total points for student 1 This all works. But what I can't figure out how to do is use a student id number to refer to a particular student (assume that two of my students have student ids as shown): grades['123456']['assign 2'] = 95 grades['314159']['assign 2'] = 83 ...or maybe create a second view with the different field names? np.sum( gview2['314159'] ) # total points for the student with the given id I know that I could create a dict mapping student ids to indices, but that seems fragile and crufty, and I'm hoping there's a better way than: id2i = { '123456': 0, '314159': 1 } np.sum( gv[ id2i['314159'] ] ) I'm also willing to re-architect things if there's a cleaner design. I'm new to NumPy, and I haven't written much code yet, so starting over isn't out of the question if I'm Doing It Wrong. I am going to be needing to sum all the assignment points for over a hundred students once a day, as well as run standard deviations and other stats. Plus, I'll be waiting on the results, so I'd like it to run in only a couple of seconds. Thanks in advance for any suggestions.

• getSharedPreferences not working for me with concerns to ListPreferences and Integers

  - by ideagent

  I'm stuck at a point where I'm trying to get my project to read a preference value (from a ListPreference listing) and then use that value in a basic mathematical subtraction instance. The problem is that the "seek" preference is not being seen by my Java code, and yet the default value is (I've tried the default value with 3000 and now 0). Am i missing something, is there a bug here, known or unknown? Java code chunk where the issues manifests itself: public static final String PREF_FILE_NAME = "preferences"; seekback.setOnClickListener(new Button.OnClickListener() { @Override public void onClick(View view) { try { SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE); Integer storedPreference = preferences.getInt("seek", 0); (mediaPlayer.getCurrentPosition()-storedPreference); } catch (Exception e) { e.printStackTrace(); } } }); Here are some other code bits for my project: From preferences file: <ListPreference android:entries="@array/seconds" android:entryValues="@array/seconds_values" android:summary="sets the seek interval for the seekback and seekforward buttons" android:title="Seek Interval" android:defaultValue="5000" android:key="@string/seek" From strings file: seek From an array file: Five seconds Fifteen seconds Thirty seconds Sixty seconds 5000 15000 30000 60000 let me know if you need to see more code to figure this one out Thanks in advance for any help that can be offered.

• Performance improvement of client server system

  - by Tanuj

  I have a legacy client server system where the server maintains a record of some data stored in a sqlite database. The data is related to monitoring access patterns of files stored on the server. The client application is basically a remote viewer of the data. When the client is launched, it connects to the server and gets the data from the server to display in a grid view. The data gets updated in real time on the server and the view in the client automatically gets refreshed. There are two problems with the current implementation: When the database gets too big, it takes a lot of time to load the client. What are the best ways to deal with this. One option is to maintain a cache at the client side. How to best implement a cache ? How can the server maintain a diff so that it only sends the diff during the refresh cycle. There can be multiple clients and each client needs to display the latest data available on the server. The server is a windows service daemon. Both the client and the server are implemented in C#
