  • Getting Started with Ruby & Ruby on Rails

    - by JakeTheSnake
    Some background: I'm a jack-of-all traits, one of which is programming. I learned VB6 through Excel and PHP for creating websites and so far it's worked out just fine for me. I'm not CS major or even mathematically inclined - logic is what interests me. Current status: I'm willing to learn new and more powerful languages; my first foray into such a route is learning Ruby. I went to the main Ruby website and did the interactive intro. (by the way, I'm currently getting redirected to google.com when I try the link...it's happening to other websites as well...is my computer infected?) I liked what I learned and wanted to get started using Ruby to create websites. I downloaded InstantRails and installed it; everything so far has been fine - the program starts up just fine, and I can test some Ruby code in the console. However my troubles begin when I try and view a web page with Ruby code present. Lastly, my problem: As in PHP, I can browse to the .php file directly and through using PHP tags and some simple 'echo' statements I can be on my way in making dynamic web pages. However with the InstantRails app working, accessing a .rb or .rhtml page doesn't produce similar results. I made a simple text file named 'test.rb' and put basic HTML tags in there (html, head, body) and the Ruby tags <%= and % with some ruby code inside. The web page actually shows the tags and the code - as if it's all just plain HTML. I take it Ruby isn't parsing the page before it is displayed to the user, but this is where my lack of understanding of the Ruby environment stops me short. Where do I go from here?

    Hello everyone, I'm getting the following error when I upload a JavaFX app to a website, but I don't get it locally.

  • How to change scope data in controller?

    - by Derooie
    I am a real newbie at angular. I created something now which will let me retrieve and add items via angular and get/put them in mongodb. I use express and mongoose in the app The question is, how can i modify the data before it reaches the DOM in the controller. In this example i have created a way to retrieve data, and i get it exactly as it is stored in mongodb. What i would like is that the field where i store 1 or 0 in the database, to be shown as text. So if mongo has a value 1 i get "the value in mongo is 1" and when the field has a value of 0 get "the value is zero". (just as an example, i like other texts, but it illustrate what i want) I post my controller, html and current output. Any help would be appreciated. Controller function getGuests($scope, $http) { $scope.formData = {}; $http.get('/api/guests') .success(function(data) { $scope.x = data; }) .error(function(data) { console.log('Error: ' + data); }); } HTML <div ng-controller="getGuests"> <div ng-repeat="guest in x"> {{ guest.voornaam }} {{ guest.aanwezig }} </div> </div> The current scope output, what i see in HTML. I like to change only the value of "aanwezig" in case the value of aanwezig is 0 or 1. firstname1 1 firstname2 0 Something else, but would be great to learn, is how i can do a specific mongodb query by the push of a button and get that result.

  • Finding text's bounding rect in Core Text

    - by Mo
    I'm trying to find the boundaries of a line of text in Core Text. For simplicity, assume it has a single character. At the moment I'm using the following method: line = CTLineCreateWithAttributedString(attrString); rect = CTLineGetImageBounds(line, context); It works most of the times, but for some characters, like math italic d (Unicode: 0x1D451) or math italic q (Unicode: 0x1D45E), the width is a bit short. I tried using CTLineGetTypographicBounds() or CTFramesetterSuggestFrameSizeWithConstraints, but they didn't help either (I think they use glyph's advance to find the width, not its graphical width.) As the font itself isn't italic, I also can't use slant angle to correct this. I tried accessing the glyphs directly and using CTFontCreatePathForGlyph(), but failed as CGGlyph and UniChar are both 16-bits and I need 32-bit characters. Does anyone know if I'm doing anything wrong? If so, what's the right way?

  • How to draw the "trail" in a maze solving application

    - by snow-spur
    Hello i have designed a maze and i want to draw a path between the cells as the 'person' moves from one cell to the next. So each time i move the cell a line is drawn Also i am using the graphics module The graphics module is an object oriented library Im importing from graphics import* from maze import* my circle which is my cell center = Point(15, 15) c = Circle(center, 12) c.setFill('blue') c.setOutline('yellow') c.draw(win) p1 = Point(c.getCenter().getX(), c.getCenter().getY()) this is my loop if mazez.blockedCount(cloc)> 2: mazez.addDecoration(cloc, "grey") mazez[cloc].deadend = True c.move(-25, 0) p2 = Point(getX(), getY()) line = graphics.Line(p1, p2) cloc.col = cloc.col - 1 Now it says getX not defined every time i press a key is this because of p2???

  • getView only shows Flagged Backgrounds for drawn Views, It does not show Flagged Background when scroll to view more items on list

    - by Leoa
    I am trying to create a listview that receives a flagged list of items to indicate a status to the user. I have been able to create the flag display by using a yellow background (see image at bottom). In Theory, the flagged list can have many flagged items in it. However in my app, only the first three flagged backgrounds are shown. I believe this is because they are initially drawn to the screen. The Flagged background that are not drawn initially to the screen do not show. I'd like to know how to get the remaining flags to show in the list. ListView Recycling: The backgrounds in the listView are being recycled in getView(). This recycling goes from position 0 to position 9. I have flags that need to match at positions 13, 14 and so on. Those positions are not being displayed. listView.getCheckedItemPositions() for multiple selections: This method will not work in my case because the user will not selected the flags. The flags are coming from the server. setNotifyOnChange() and/or public virtual void SetNotifyOnChange (bool notifyOnChange): I'm not adding new data to the list, so I don't see how this method would work for my program. Does this method communicate to getview when it is recycling data? I was unable to find an answer to this in my research. public void registerDataSetObserver: This may be overkill for my problem, but is it possible to have an observer object that keeps track of the all the positions in my items list and in my flag list no matter if the view is recycled and match them on the screen? Code: package com.convention.notification.app; import java.util.Iterator; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Context; import android.graphics.Color; import android.os.Bundle; import android.text.Html; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.ViewParent; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.TextView; public class NewsRowAdapter extends ArrayAdapter<Item> { private Activity activity; private List<Item> items; private Item objBean; private int row; private List<Integer> disable; View view ; int disableView; public NewsRowAdapter(Activity act, int resource, List<Item> arrayList, List<Integer> disableList) { super(act, resource, arrayList); this.activity = act; this.row = resource; this.items = arrayList; this.disable=disableList; System.out.println("results of delete list a:"+disable.toString()); } public int getCount() { return items.size(); } public Item getItem(int position) { return items.get(position); } public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { for(int k =0;k < disable.size();k++){ if(position==disable.get(k)){ //System.out.println( "is "+position+" value of disable "+disable.get(k)); disableView=disable.get(k); //AdapterView.getItemAtPosition(position); } } return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { View view = convertView; ViewHolder holder; if (view == null) { LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); view = inflater.inflate(row, null); getItemViewType(position); long id=getItemId(position); if(position==disableView){ view.setBackgroundColor(Color.YELLOW); System.out.println(" background set to yellow at position "+position +" disableView is at "+disableView); }else{ view.setBackgroundColor(Color.WHITE); System.out.println(" background set to white at position "+position +" disableView is at "+disableView); } //ViewHolder is a custom class that gets TextViews by name: tvName, tvCity, tvBDate, tvGender, tvAge; holder = new ViewHolder(); /* setTag Sets the tag associated with this view.

  • Handling newline character in input between Windows and Linux

    - by Fazal
    I think this is a standard problem which may have been asked before but I could not get the exact answer so posting the issue. The issue is that our server is running on a linux box. We access the server over the browser on a window box to enter data into field which is supposed to contain multiple lines which user can enter by pressing the enter key after each line Abc Def GHI When this input field (this is a text area),is read on the linux machine, we want to split the data based on new line character. I had three question on this. Does the incoming data contain "\r\n" or "\n" If incoming data does contain "\r\n", the linux line.separator property (vm property) would not work for me as it would say "\n" and therefore may leave "\r" in the data. If "\r" is left in the data, if I open the file on a windows machine, will this mean a newline character? Finally can anyone tell me the standard way to deal with this issue?

  • inserting std::strings in to a std::map

    - by PaulH
    I have a program that reads data from a file line-by-line. I would like to copy some substring of that line in to a map as below: std::map< DWORD, std::string > my_map; DWORD index; // populated with some data char buffer[ 1024 ]; // populated with some data char* element_begin; // points to some location in buffer char* element_end; // points to some location in buffer > element_begin my_map.insert( std::make_pair( index, std::string( element_begin, element_end ) ) ); This std::map<>::insert() operation takes a long time (It doubles the file parsing time). Is there a way to make this a less expensive operation? Thanks, PaulH

  • ComDlg32.ocx Error: Object doesn't support this property or method

    - by abhilashca
    I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

  • C# How to perform a live xslt transformation on an in memory object?

    - by JL
    I have a function that takes 2 parameters : 1 = XML file, 2 = XSLT file, then performs a transformation and returns the resulting HTML. Here is the function: /// <summary> /// Will apply an XSLT style to any XML file and return the rendered HTML. /// </summary> /// <param name="xmlFileName"> /// The file name of the XML document. /// </param> /// <param name="xslFileName"> /// The file name of the XSL document. /// </param> /// <returns> /// The rendered HTML. /// </returns> public string TransformXml(string xmlFileName, string xslFileName) { var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); var xslt = new System.Xml.Xsl.XslCompiledTransform(); xslt.Load(xslFileName); var stm = new MemoryStream(); xslt.Transform(xd, null, stm); stm.Position = 1; var sr = new StreamReader(stm); xtr.Close(); return sr.ReadToEnd(); } I want to change the function not to accept a file for the XML, but instead just an object. The object is exactly compatible with the xslt, if it was serialized to file. But I don't want to have to serialize it to a file first. So to recap : keep the xslt coming from a file, but the xml input should an object I pass and would like to generate the xml from without any file system interaction.

  • Visual Studio 2008 Web Project problem with PNG files

    - by NoCarrier
    I've added a PNG file to a directory in my VS2k8 webforms project, and when I run the app, it refuses to render my image - it even knows the dimensions but renders a box with a red X. Oddly enough, if I double click the PNG file within VS2k8, it opens up in the IDE and displays fine (but only within the IDE). Does anyone have any clues? The path is correct.. I just have a basic default.aspx page with this in the body <img src="img/logo.png" /> if i navigate to img/logo.png in the browser, it shows a box with the same dimensions as my image, but a red x. Its finding the image, just not rendering it. It's showing up in IE running under the vs2k8 web server (localhost:5512/default.aspx) I've dropped a JPG in the same directory, and it shows up just fine. I'm not sure what type of PNG it is, but here is the kicker.... If i make an HTML file that references that image, copy both this HTML file and PNG file to my webserver (or just double click on the HTML page), it comes up JUST FINE. Its leading me to believe that the Visual Studio web server may not recognize PNG files (at least this one) properly?

  • How to I pass parameters to Ruby/Python scripts from inside PHP?

    - by Roger
    Hi, everybody. I need to turn HTML into equivalent Markdown-structured text. From what I could discover, I have only two good choices: Python: Aaron Swartz's html2text.py Ruby: Singpolyma's html2markdown.rb As I am programming in PHP, I need to pass the HTML code, call the Ruby/Python Script and receive the output back. I started creating a simple test just to know if my server was configured to run both languages. PHP code: echo exec('./hi.rb'); Ruby code: #!/usr/bin/ruby puts "Hello World!" It worked fine and I am ready to go to the next step. Unfortunately, all I know is that the function is Ruby works like this: HTML2Markdown.new('<h1>HTMLcode</h1>').to_s I don't know how to make PHP pass the string (with the HTML code) to Ruby nor how to make the ruby script receive the variable and pass it back to PHP (after have parsed it into Markdown). Believe it or not: I know less of Python. A folk made a similar question here ("how to call ruby script from php?") but with no practical information to my case. Any help would be a joy - thanks.

  • Handle mysql restart in SQLAlchemy

    - by wRAR
    My Pylons app uses local MySQL server via SQLAlchemy and python-MySQLdb. When the server is restarted, open pooled connections are apparently closed, but the application doesn't know about this and apparently when it tries to use such connection it receives "MySQL server has gone away": File '/usr/lib/pymodules/python2.6/sqlalchemy/engine/default.py', line 277 in do_execute cursor.execute(statement, parameters) File '/usr/lib/pymodules/python2.6/MySQLdb/cursors.py', line 166 in execute self.errorhandler(self, exc, value) File '/usr/lib/pymodules/python2.6/MySQLdb/connections.py', line 35 in defaulterrorhandler raise errorclass, errorvalue OperationalError: (OperationalError) (2006, 'MySQL server has gone away') This exception is not caught anywhere so it bubbles up to the user. If I should handle this exception somewhere in my code, please show the place for such code in a Pylons WSGI app. Or maybe there is a solution in SA itself?

  • View Models (ViewData), UserControls/Partials and Global variables - best practice?

    - by elado
    Hi I'm trying to figure out a good way to have 'global' members (such as CurrentUser, Theme etc.) in all of my partials as well as in my views. I don't want to have a logic class that can return this data (like BL.CurrentUser) I do think it needs to be a part of the Model in my views So I tried inheriting from BaseViewData with these members. In my controllers, in this way or another (a filter or base method in my BaseController), I create an instance of the inheriting class and pass it as a view data. Everything's perfect till this point, cause then I have my view data available on the main View with the base members. But what about partials? If I have a simple partial that needs to display a blog post then it looks like this: <%@ Control Language="C#" AutoEventWireup="true" Inherits="ViewUserControl<Post>" %> and simple code to render this partial in my view (that its model.Posts is IEnumerable<Post>): <%foreach (Post p in this.Model.Posts) {%> <%Html.RenderPartial("Post",p); %> <%}%> Since the partial's Model isn't BaseViewData, I don't have access to those properties. Hence, I tried to make a class named PostViewData which inherits from BaseViewData, but then my containing views will have a code to actually create the PostViewData in them in order to pass it to the partial: <%Html.RenderPartial("Post",new PostViewData { Post=p,CurrentUser=Model.CurrentUser,... }); %> Or I could use a copy constructor <%Html.RenderPartial("Post",new PostViewData(Model) { Post=p }); %> I just wonder if there's any other way to implement this before I move on. Any suggestions? Thanks!

  • What's the scope of a Javascript variable declared in a for() loop?

    Check out the following snippet of HTML/Javascript code: <html> <head> <script type="text/javascript"> var alerts = []; for(var i = 0; i < 3; i++) { alerts.push(function() { document.write(i + ', '); }); } for (var j = 0; j < 3; j++) { (alerts[j])(); } for (var i = 0; i < 3; i++) { (alerts[i])(); } </script> </head><body></body></html> This outputs: 3, 3, 3, 0, 1, 2 which isn't what I was expecting - I was expecting the output 0, 1, 2, 0, 1, 2, I (incorrectly) assumed that the anonymous function being pushed into the array would behave as a closure, capturing the value of i that's assigned when the function is created - but it actually appears that i is behaving as a global variable. Can anyone explain what's happening to the scope of i in this code example, and why the anonymous function isn't capturing its value?

  • Stream/string/bytearray transformations in Python 3

    - by Craig McQueen
    Python 3 cleans up Python's handling of Unicode strings. I assume as part of this effort, the codecs in Python 3 have become more restrictive, according to the Python 3 documentation compared to the Python 2 documentation. For example, codecs that conceptually convert a bytestream to a different form of bytestream have been removed: base64_codec bz2_codec hex_codec And codecs that conceptually convert Unicode to a different form of Unicode have also been removed (in Python 2 it actually went between Unicode and bytestream, but conceptually it's really Unicode to Unicode I reckon): rot_13 My main question is, what is the "right way" in Python 3 to do what these removed codecs used to do? They're not codecs in the strict sense, but "transformations". But the interface and implementation would be very similar to codecs. I don't care about rot_13, but I'm interested to know what would be the "best way" to implement a transformation of line ending styles (Unix line endings vs Windows line endings) which should really be a Unicode-to-Unicode transformation done before encoding to byte stream, especially when UTF-16 is being used, as discussed this other SO question.

  • Stack trace in website project, when debug = false

    - by chandmk
    We have a website project. We are logging unhanded exceptions via a appdomain level exception handler. When we set debug= true in web.config, the exception log is showing the offending line numbers in the stack trace. But when we set debug = false, in web.config, log is not displaying the line numbers. We are not in a position to convert the website project in to webapplication project type at this time. Its legacy application and almost all the code is in aspx pages. We also need to leave the project in 'updatable' mode. i.e. We can't user pre-compile option. We are generating pdb files. Is there anyway to tell this kind of website projects to generate the pdb files, and show the line numbers in the stack trace?

  • How to develop modular web UIs with Django?

    - by nh2
    When doing larger sites in "big business", you most probalbly work in a team with several developers. Let's say dev A makes a form to insert new user data, B creates a user list, C makes some privilege administration and D does crazy statistic graphs work with image generation and so on. Each dev begins to develop his own component, creates a view and a template and tests that independently, until each component works. Now, the client wants to have all those components on one bit HTML page. How to achieve this? How to assemble different views/templates in a form of composition so that they remain modular and can be developed and tested independently? It seems inheritance is not the way to go because all of those UI components are equal and there is no hierarchy. The idea of the assembling template is something like <html> <head> // include the css for the components and their assembly </head> <body> // include user data form here <some containers, images, and so on> // show user list // show privilege administration in this part // and finally, the nice statistic graphs // perhaps, we want to display some other components here in future </body> </html> I have not found an answer on the net yet. Most people come up with one big template which just implements all of the UI functionality, removing all modularity. Each component shall have its own template and view dealing only with that component developed by one person each, and they then shall be sticked together just like bricks. I would highly appreciate any hints!

  • Use a Trendline Formula to Get Values for Any Given X with Excel

    - by kirkouimet
    Is there an easy way to apply the trend line formula from a chart to any given X value in Excel? For example, I want to get the Y value for a given X = $2,006.00. I've already taken the formula and retyped it out be: =-0.000000000008*X^3 - 0.00000001*X^2 + 0.0003*X - 0.0029 I am continually making adjustments to the trend line by adding more data, and don't want to retype out the formula every time.
