  • Simplest PHP Routing framework .. ?

    - by David
    I'm looking for the simplest implementation of a routing framework in PHP, in a typical PHP environment (Running on Apache, or maybe nginx) .. It's the implementation itself I'm mostly interested in, and how you'd accomplish it. I'm thinking it should handle URL's, with the minimal rewriting possible, (is it really a good idea, to have the same entrypoint for all dynamic requests?!), and it should not mess with the querystring, so I should still be able to fetch GET params with $_GET['var'] as you'd usually do.. So far I have only come across .htaccess solutions that puts everything through an index.php, which is sort of okay. Not sure if there are other ways of doing it. How would you "attach" what URL's fit to what controllers, and the relation between them? I've seen different styles. One huge array, with regular expressions and other stuff to contain the mapping. The one I think I like the best is where each controller declares what map it has, and thereby, you won't have one huge "global" map, but a lot of small ones, each neatly separated. So you'd have something like: class Root { public $map = array( 'startpage' => 'ControllerStartPage' ); } class ControllerStartPage { public $map = array( 'welcome' => 'WelcomeControllerPage' ); } // Etc ... Where: 'http://myapp/' // maps to the Root class 'http://myapp/startpage' // maps to the ControllerStartPage class 'http://myapp/startpage/welcome' // maps to the WelcomeControllerPage class 'http://myapp/startpage/?hello=world' // Should of course have $_GET['hello'] == 'world' What do you think? Do you use anything yourself, or have any ideas? I'm not interested in huge frameworks already solving this problem, but the smallest possible implementation you could think of. I'm having a hard time coming up with a solution satisfying enough, for my own taste. There must be something pleasing out there that handles a sane bootstrapping process of a PHP application without trying to pull a big magic hat over your head, and force you to use "their way", or the highway! ;)

  • Difference in regex between Python and Rubular?

    - by Rosarch
    In Rubular, I have created a regular expression: (Prerequisite|Recommended): (\w|-| )* It matches the bolded: Recommended: good comfort level with computers and some of the arts. Summer. 2 credits. Prerequisite: pre-freshman standing or permission of instructor. Credit may not be applied toward engineering degree. S-U grades only. Here is a use of the regex in Python: note_re = re.compile(r'(Prerequisite|Recommended): (\w|-| )*', re.IGNORECASE) def prereqs_of_note(note): match = note_re.match(note) if not match: return None return match.group(0) Unfortunately, the code returns None instead of a match: >>> import prereqs >>> result = prereqs.prereqs_of_note("Summer. 2 credits. Prerequisite: pre-fres hman standing or permission of instructor. Credit may not be applied toward engi neering degree. S-U grades only.") >>> print result None What am I doing wrong here?

  • SQL Server 2005 Import from Excel

    - by user327045
    I'd like to know what my best option would be to import data from an excel file on a weekly or monthly basis. At first, I thought I would use SSIS, but after much struggle with seemingly simple tasks, I'm starting to rethink my plan. Would it be better/easier to just write the SQL by hand or use the services of an SSIS package? The basic process will be as follows: A separate process will download an .xls file to a local fileshare. The xls file will have a filename like: 'myfilename MON YY'. I will need to read the month and year from the the filename, reformat it to a sql date and then query a DimDate table to find the corresponding date key. For each row (after the first 2 header rows), insert the data with the date key, unless the row is a total row, then ignore. Here are some of the issues I've been encountering with SSIS: I can parse the date string from a flat file datasource, but can't seem to do it with an excel data source. Also, once parsed, i cannot seem to convert the string to a date in order to perform the lookup for the date key. For example, I want to do something like this: select DateKey from DimDate where ActualDate = convert(datetime, '01-' + 'JAN-10', 120) but i don't think it is possible to use the 'convert' or 'datetime' keywords in an expression builder. I have been also unable to find where I can edit the SQL to ignore the first 2 rows of data. I'm very skeptical of using SSIS because it seems like a Kludgy way of doing something that can probably be accomplished more efficiently writing the SQL yourself, but I may be forced to use SSIS. Thoughts?

  • Having trouble creating vectors of System::String^

    - by Justen
    So I have a regex expression to parse certain parts of a file name. I'm trying to store each part in its own vector until I use it later, but it won't let me. One error I get when I try making a vector of System::String^ is that error C3698: 'System::String ^' : cannot use this type as argument of 'new' Then, when I try just making a vector of std::string, it can't implicitly convert to type System::String^, and casting won't work either. void parseData() { System::String^ pattern = "(\\D+)(\\d+)(\\w{1})(\\d+)\\.(\\D{3})"; std::vector < System::String^ > x, y, filename, separator; Regex re( pattern ); for ( int i = 0; i < openFileDialog1->FileNames->Length; i++ ) { Match^ m = re.Match( openFileDialog1->FileNames[i] ); filename.push_back( m->Groups[0]->Value );/* x.push_back( m->Groups[1]->Value ); separator.push_back( m->Groups[2]->Value ); y.push_back( m->Groups[3]->Value );*/ } }

  • How to safely transfer reference to object across window?

    - by Morgan Cheng
    I'm debugging a web application. Javasript in one window create one object and use it as argument to invoke global method in another window. Pseudo code is like below. var obj = new Foo(); anotherWin.bar(obj); In anotherWin, the argument is stored in global variable. var g_obj; function bar(obj) { g_obj = obj; ... } When other function tries to reference g_obj.Id, it throws exception "Cannot evaluate expression". This happens in IE8.0.7600.16385 on Windows 7. In Visual Studio debugger, when this exception happens, the g_obj shows as {...} It looks all its properties are lost. Perhaps the root reason is the object is created in one window but only referenced in another window. The object might be garbage-collected at any time. Is there any way to work around this?

  • Populating a foreign key table with variable user input

    - by Vincent
    I'm working on a website that will be based on user contributed data, submitted using a regular HTML form. To simplify my question, let's say that there will be two fields in the form: "User Name" and "Country" (this is just an example, not the actual site). There will be two tables in the database : "countries" and "users," with "users.country_id" being a foreign key to the "countries" table (one-to-many). The initial database will be empty. Users from all over the world will submit their names and the countries they live in and eventually the "countries" table will get filled out with all of the country names in the world. Since one country can have several alternative names, input like Chile, Chili, Chilli will generate 3 different records in the countries table, but in fact there is only one country. When I search for records from Chile, Chili and Chilli will not be included. So my question is - what would be the best way to deal with a situation like this, with conditions such that the initial database is empty, no other resources are available and everything is based on user input? How can I organize it in such way that Chile, Chili and Chilli would be treated as one country, with minimum manual interference. What are the best practices when it comes to normalizing user submitted data and is there a scientific term for this? I'm sure this is a common problem. Again, I used country names just to simplify my question, it can be anything that has possible different spellings.

  • oracle plsql select pivot without dynamic sql to group by

    - by kayhan yüksel
    To whom it may respond to, We would like to use SELECT function with PIVOT option at a 11g r2 Oracle DBMS.

  • Tools\addin's for formating or cleaning up xaml?

    - by cody
    I'm guessing these don't exist since I searched around for these but I'm looking for a few tools: 1) A tool that cleans up my xaml so that the properties of elements are consistent through a file. I think enforcing that consistence would make the xaml easier to read. Maybe there could be a hierarchy of what comes first but if not alphabetical might work. Example before: TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4" TextBox Grid.Column="1" Margin="4" Name="t2" Grid.Row="3" Example after: TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4" TextBox Name="t2" Grid.Row="3" Grid.Column="1" Margin="4" (note < / has been remove from the above since control seem to have issues parsing whe the after section was added) 2) Along the same lines as above, to increase readability, a tool to align properties, so from the above code example similar props would start in the same place. <TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4"/> <TextBox Name="t2" Grid.Row="3" Grid.Column="1" Margin="4"/> I know VS has default settings for XAML documents so props can be on one line or separate lines so maybe if there was a tool as described in (1) this would not be needed...but it would still be nice if you like your props all on one line. 3) A tool that adds X to the any of the Grid.Row values and Y to any of the Grid.Column values in the selected text. Every time I add a new row\column I have to go manually fix these. From my understanding Expression Blend can help with this but seem excessive to open Blend just to increment some numbers (and just don't grok Blend). Maybe vs2010 with the designer will help but right now I'm on VS08 and Silverlight. Any one know of any tools to help with this? Anyone planning to write something like this...I'm looking at you JetBrains and\or DevExpress. Thanks.

  • activemerchant PayPalExpress transaction is invalid

    - by Ameya Savale
    I am trying to integrate activemerchant into my ruby on rails application. This is my controller where I get the purchase attirbutes and create a PaypalExpressResponse object def checkout total_as_cents, purchase_params = get_setup_params(Schedule.find(params[:schedule]), request) setup_response = @gateway.setup_purchase(total_as_cents, purchase_params) redirect_to @gateway.redirect_url_for(setup_response.token) end @gateway is my PaypalExpressGateway object which I create using this method in my controller def assign_gateway @gateway = PaypalExpressGateway.new( :login => api_user, :password => api_pass, :signature => api_signature ) end I got the api_user, api_pass, and api_signature values from my developer.paypal.com account, when I logged in for the first time there was already a sandbox user created as a merchant which is where I got the api credentials from. And finally here is my get_setup_params method: def get_setup_params(schedule, request) purchase_params = { :ip => request.remote_ip, :return_url => url_for(:action => 'review', :only_path => false, :sched => schedule.id), :cancel_return_url => register_path, :allow_note => true, :item => schedule.id } return to_cents(schedule.fee), purchase_params end How ever when I click on the checkout button, I get redirected to a sandbox paypal page saying "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." I'm not sure exactly what's wrong, I think the problem lies in the credentials but don't know why. Any help will be appreciated. One other point, I'm running this in my development environment so I have put this in my config file config.after_initialize do ActiveMerchant::Billing::Base.mode = :test end UPDATE Found out what the problem was, my return cancel url was invalid instead of using register_path, I used url_for(action: "action-name", :only_path => false) this answer helped me Rails ActiveMerchant - Paypal Express Checkout Error even though I wasn't able to see the output of the response like the person has managed to do

  • Python raw strings and trailing back slashes.

    - by dash-tom-bang
    I ran across something once upon a time and wondered if it was a Python "bug" or at least a misfeature. I'm curious if anyone knows of any justifications for this behavior. I thought of it just now reading "Code Like a Pythonista," which has been enjoyable so far. I'm only familiar with the 2.x line of Python. Raw strings are strings that are prefixed with an r. This is great because I can use backslashes in regular expressions and I don't need to double everything everywhere. It's also handy for writing throwaway scripts on Windows, so I can use backslashes there also. (I know I can also use forward slashes, but throwaway scripts often contain content cut&pasted from elsewhere in Windows.) So great! Unless, of course, you really want your string to end with a backslash. There's no way to do that in a 'raw' string. In [9]: r'\n' Out[9]: '\\n' In [10]: r'abc\n' Out[10]: 'abc\\n' In [11]: r'abc\' ------------------------------------------------ File "<ipython console>", line 1 r'abc\' ^ SyntaxError: EOL while scanning string literal In [12]: r'abc\\' Out[12]: 'abc\\\\' So one slash before the closing quote is an error, but two slashes gives you two slashes! Certainly I'm not the only one that is bothered by this? Thoughts on why 'raw' strings are 'raw, except for slash-quote'? I mean, if I wanted to embed a single quote in there I'd just use double quotes around the string, and vice versa. If I wanted both, I'd just triple quote. If I really wanted three quotes in a row in a raw string, well, I guess I'd have to deal, but is this considered "proper behavior"?

  • jQuery AJAX Redirection problem

    - by meosoft
    Hello please consider this: On page A I have a link that takes you to page B when JS is off, but when JS is on, I want to replace content on current page with content from the page B. Pages A and B are in fact the same script that is able to tell AJAX calls from regular ones and serve the content appropriately. Everything works fine, as long as there are no redirects involved. But, sometimes there is a 301 redirect and what seems to be happening is that client browser then makes a second request, which will return with a 200 OK. Only the second request is sent without a X-Requested-With header, therefore I cannot tell within my script wether it came from AJAX or not, and will send a complete page instead of just the content. I have tried checking for 301 status code in my error, success, and complete handlers but none of them worked. It seems to be handling the 301 behind the scenes. Could anyone help me with this? jQuery 1.4, PHP 5 Edit: People requested the code to this, which I didn't think was necessary but here goes: // hook up menu ajax loading $('#menu a').live("click", function(){ // update menu highlight if($(this).parents('#menu').size() > 0){ $("#menu>li").removeClass("current_page_item"); $(this).parent().addClass("current_page_item"); } // get the URL where we will be retrieving content from var url = $(this).attr('href'); window.location.hash = hash = url; $.ajax({ type: "GET", url: url, success: function(data){ // search for an ID that is only present if page is requested directly if($(data).find('#maincontent').size() > 0){ data = $(data).find('#maincontent .content-slide *').get(); } // the rest is just animating the content into view $("#scroller").html(data); $('.content-slide').each(setHeight); $('.content-slide').animate({ left: "0px" }, 1000, 'easeOutQuart', function(){ $('#home').css("left", "-760px").html(data); $('#scroller').css("left", "-760px"); $('.content-slide').each(setHeight); } ); } }); return false; });

  • WordPress plugin to output a certain category on content page tweak help

    - by talkingD0G
    I'm using WordPress plugin Category Page to display the most recent 5 posts from a certain category on a regular content page (not the blog page) of a website. Right now the plugin is limited to display the post title linked to the post page. This is a video blog type site and I need the plugin to display the post title (as it does now) with the video as well. Probably just telling the script to show the content would work but I don't know how to tweak it. This is the section of the script that is outputting the post title: function page2cat_content_catlist($content){ global $post; if ( stristr( $content, '[catlist' )) { $search = "@(?:<p>)*\s*\[catlist\s*=\s*(\w+|^\+)\]\s*(?:</p>)*@i"; if (preg_match_all($search, $content, $matches)) { if (is_array($matches)) { $title = get_option('p2c_catlist_title'); if($title != "") $output = "<h4>".$title."</h4>"; else $output = ""; $output .= "<ul class='p2c_catlist'>"; $limit = get_option('p2c_catlist_limit'); foreach ($matches[1] as $key =>$v0) { $catposts = get_posts('category='.$v0."&numberposts=".$limit); foreach($catposts as $single): $output .= "<li><a href='".get_permalink($single->ID)." '>".$single->post_title."</a></li>"; endforeach; $search = $matches[0][$key]; $replace= $output; $content= str_replace ($search, $replace, $content); } $output .= "</ul>"; } } } return $content; } If anyone has any advice or knows how to help thanks in advance!

  • Is it impossible to secure .net code (intellectual property) ?

    - by JL
    I used to work in JavaScript a lot and one thing that really bothered my employers was that the source code was too easy to steal. Even with obfuscation, nothing really helped, because we all knew that any competent developer would be able to read that code if they wanted to. JS Scripts are one thing, but what about SOA projects that have millions invested in IP (Intellectual Property). I love .net, and especially C#, but I recently again had to answer the question "If we give this compiled program over to our clients, can their developers reverse engineer it?" I had gone out of my way to obfuscate the code, but I knew it wouldn't take that much for another determined C# developer to get at the code. So I earnestly pose the question, is it impossible to secure .net code? The considerations I have as as follows: Even regular native executables can be reversed, but not every developer has the skill to be able to do this. Its a lot harder to disassemble a native executable than a .net assembly. Obfuscation will only get you so far, but it does help a little. Why have I never seen any public acknowledgement by Microsoft that anything written in .net is subject to relatively easy IP theft? Why have I never seen a scrap of counter measure training on any Microsoft site? Why does VS come with a community obfuscater as an optional component? Ok maybe I have just had my head in the sand here, but its not exactly high on most developers priority list. Are there any plans to address my concerns in any future version of .net? I'm not knocking .net, but I would like some realistic answers, thank you, question marked as subjective and community!

  • A "smart" (forgiving) date parser?

    - by jdmuys
    I have to migrate a very large dataset from one system to another. One of the "source" column contains a date but is really a string with no constraint, while the destination system mandates a date in the format yyyy-mm-dd. Many, but not all, of the source dates are formatted as yyyymmdd. So to coerce them to the expected format, I do (in Perl): return "$1-$2-$3" if ($val =~ /(\d{4})[-\/]*(\d{2})[-\/]*(\d{2})/); The problem arises when the source dates moves away from the "generic" yyyymmdd. The goal is to salvage as many dates as possible, before giving up. Example source strings include: 21/3/1998, March 2004, 2001, 3/4/97 I can try to match as many of the examples I can find with a succession of regular expressions such as the one above. But is there something smarter to do? Am I not reinventing the wheel? Is there a library somewhere doing something similar? I couldn't find anything relevant googling "forgiving date parser". (any language is OK).

  • Silverlight MVVM Confusion: Updating Image Based on State

    - by senfo
    I'm developing a Silverlight application and I'm trying to stick to the MVVM principals, but I'm running into some problems changing the source of an image based on the state of a property in the ViewModel. For all intents and purposes, you can think of the functionality I'm implementing as a play/pause button for an audio app. When in the "Play" mode, IsActive is true in the ViewModel and the "Pause.png" image on the button should be displayed. When paused, IsActive is false in the ViewModel and "Play.png" is displayed on the button. Naturally, there are two additional images to handle when the mouse hovers over the button. I thought I could use a Style Trigger, but apparently they're not supported in Silverlight. I've been reviewing a forum post with a question similar to mine where it's suggested to use the VisualStateManager. While this might help with changing the image for hover/normal states, the part missing (or I'm not understanding) is how this would work with a state set via the view model. The post seems to apply only to events rather than properties of the view model. Having said that, I also haven't successfully completed the normal/hover affects, either. Below is my Silverlight 4 XAML. It should also probably be noted I'm working with MVVM Light. <UserControl x:Class="Foo.Bar.MyUserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" mc:Ignorable="d" d:DesignHeight="100" d:DesignWidth="200"> <UserControl.Resources> <Style x:Key="MyButtonStyle" TargetType="Button"> <Setter Property="IsEnabled" Value="true"/> <Setter Property="IsTabStop" Value="true"/> <Setter Property="Background" Value="#FFA9A9A9"/> <Setter Property="Foreground" Value="#FF000000"/> <Setter Property="MinWidth" Value="5"/> <Setter Property="MinHeight" Value="5"/> <Setter Property="Margin" Value="0"/> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalAlignment" Value="Top" /> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Cursor" Value="Hand"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Grid> <Image Source="/Foo.Bar;component/Resources/Icons/Bar/Play.png"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="Active"> <VisualState x:Name="MouseOver"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="/Foo.Bar;component/Resources/Icons/Bar/Play_Hover.png" /> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Button Style="{StaticResource MyButtonStyle}" Command="{Binding ChangeStatus}" Height="30" Width="30" /> </Grid> </UserControl> What is the proper way to update images on buttons with the state determined by the view model? Update I changed my Button to a ToggleButton hoping I could use the Checked state to differentiate between play/pause. I practically have it, but I ran into one additional problem. I need to account for two states at the same time. For example, Checked Normal/Hover and Unchecked Normal/Hover.

  • Object-oriented GUI development in python

    - by ptabatt
    Hey guys, new programmer here. I have an assignment for class and I'm stuck... What I need to do is a create a GUI that gives someone a basic arithmetic problem in one box, asks the person to answer it, evaluates it, and tells you if you're right or wrong... Basically, what I have is this: [code] class Lesson(Frame): def init (self, parent=None): Frame.init(self, parent) self.pack() Lesson.make_widgets(self) def make_widgets(self): Label(self, text="").pack(side=TOP) ent = Entry(self) self.a = randrange(1,10) self.b = randrange(1,10) self.expr = choice(["+","-"]) ent.insert(END, str(self.a) + str(self.expr) + str(self.a)) [/code] I've broken this down into many little steps and basically, what I'm trying to do right now is insert a default random expression into the first entry widget. When I run this code, I just get a blank Label. Why is that? How can I put a something like "7+7" into the box? If you absolutely need background to the problem, it's question #3 on this link. http://reed.cs.depaul.edu/lperkovic/csc242/homeworks/Homework8.html -Thanks for all help in advance.

  • Is there a way to parse XML via SAX/DOM with line numbers available per node.

    - by Chris
    I already have written a DOM parser for a large XML document format that contains a number of items that can be used to automatically generate Java code. This is limited to small expressions that are then merged into a dynamically generated Java source file. So far - so good. Everything works. BUT - I wish to be able to embed the line number of the XML node where the Java code was included from (so that if the configuration contains uncompilable code, each method will have a pointer to the source XML document and the line number for ease of debugging). I don't require the line number at parse-time and I don't need to validate the XML Source Document and throw an error at a particular line number. I need to be able to access the line number for each node and attribute in my DOM or per SAX event. Any suggestions on how I might be able to achieve this? P.S. Also, I read the StAX has a method to obtain line number whilst parsing, but ideally I would like to achieve the same result with regular SAX/DOM processing in Java 4/5 rather than become a Java 6+ application or take on extra .jar files.

  • Set "Start With" value for Oracle sequence dynamically

    - by Allan
    I'm trying to create a release script that can be deployed on multiple databases, but where the data can be merged back together at a later date. The obvious way to handle this is to set the sequence numbers for production data sufficiently high in subsequent deployments to prevent collisions. The problem is in coming up with a release script that will accept the environment number and set the "Start With" value of the sequences appropriately. Ideally, I'd like to use something like this: ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] CREATE SEQUENCE seq1 START WITH &EnvironNum*100000; --[more scripting] This doesn't work because you can't evaluate a numeric expression in DDL. Another option is to create the sequences using dynamic SQL via PL/SQL. ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] EXEC execute immediate 'CREATE SEQUENCE seq1 START WITH ' || &EnvironNum*100000; --[more scripting] However, I'd prefer to avoid this solution as I generally try to avoid issuing DDL in PL/SQL. Finally, the third option I've come up with is simply to accept the Start With value as a substitution variable, instead of the environment number. Does anyone have a better thought on how to go about this?

  • What do we log and why do we log it?

    - by Lucas
    This has been bugging me for quite some time. Reading various questions on SO, blogs and listening to colleagues, I keep hearing how important "logging" is. How various logging frameworks stack up against each other, and how there are so many to pick from it's (apparently) ridiculous. Now, I know what logging is. What I don't know is what is supposed to be logged and why. Sure, I can guess. Exceptions? Sounds like something one might want to log... but which exceptions? And is it only exceptions? And what do I do with the logged information? If it's an in-house app, then that could probably be put to good use, but if it's a commercial desktop application, how is the log of... whatever... helping anyone? I doubt regular users would be peeking inside. Is it then something you ask the users to provide on request? I'm deeply frustrated by my own ignorance in this. It's also surprising how little information there is about this. The info on the websites of the various logging frameworks is all written for an audience that already knows what it wants to log, and knows why it needs to do so. Same things goes for the various discussions on SO about logging, like for instance this highly voted up question on Logging best practices. For a question with so many votes, it's almost comical how there's next to nothing in there that would answer my what and why questions. So being finally fed up, I'm asking here: what do people log, and why do they log it?

  • How to access a TextView element in a BroadcastReceiver

    - by ric03uec
    Hello, I am testing a simple widget in android and using Alarms to update a TextView at regular intervals. The problem is that in the BroadcastReceiver class I cannot access the TextView element, which I want to get updated when the alarm expires. The class is being called properly because the Toast i have put there is giving the appropriate message. The following code is from the class where I configure the widget and set the timers. public void onCreate(Bundle bundle) { super.onCreate(bundle); Intent intent = getIntent(); Bundle extras = intent.getExtras(); if(extras != null){ mWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(WidgetConfigure.this); RemoteViews views = new RemoteViews(WidgetConfigure.this.getPackageName(), R.layout.widget_layout); views.setTextViewText(R.id.quote, "Widget Loaded From Activity"); appWidgetManager.updateAppWidget(mWidgetId, views); setTimer(); //set the timers... setResult();// set the result... } } Now i want to update the same TextView when the BroadCastReceiver is called after the timer expires. I have tried the code provided in the ExampleAppWidget example provided in android api demos and that isnt working out. How can i set the required text? Thankx in advance

  • What's the best way to resolve this scope problem?

    - by Peter Stewart
    I'm writing a program in python that uses genetic techniques to optimize expressions. Constructing and evaluating the expression tree is the time consumer as it can happen billions of times per run. So I thought I'd learn enough c++ to write it and then incorporate it in python using cython or ctypes. I've done some searching on stackoverflow and learned a lot. This code compiles, but leaves the pointers dangling. I tried 'this_node = new Node(...' . It didn't seem to work. And I'm not at all sure how I'd delete all the references as there would be hundreds. I'd like to use variables that stay in scope, but maybe that's not the c++ way. What is the c++ way? class Node { public: char *cargo; int depth; Node *left; Node *right; } Node make_tree(int depth) { depth--; if(depth <= 0) { Node tthis_node("value",depth,NULL,NULL); return tthis_node; } else { Node this_node("operator" depth, &make_tree(depth), &make_tree(depth)); return this_node; } };

  • C++ Switch won't compile with externally defined variable used as case

    - by C Nielsen
    I'm writing C++ using the MinGW GNU compiler and the problem occurs when I try to use an externally defined integer variable as a case in a switch statement. I get the following compiler error: "case label does not reduce to an integer constant". Because I've defined the integer variable as extern I believe that it should compile, does anyone know what the problem may be? Below is an example: test.cpp #include <iostream> #include "x_def.h" int main() { std::cout << "Main Entered" << std::endl; switch(0) { case test_int: std::cout << "Case X" << std::endl; break; default: std::cout << "Case Default" << std::endl; break; } return 0; } x_def.h extern const int test_int; x_def.cpp const int test_int = 0; This code will compile correctly on Visual C++ 2008. Furthermore a Montanan friend of mine checked the ISO C++ standard and it appears that any const-integer expression should work. Is this possibly a compiler bug or have I missed something obvious? Here's my compiler version information: Reading specs from C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/specs Configured with: ../gcc-3.4.5-20060117-3/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enable-hash-synchronization --enable-libstdcxx-debug Thread model: win32 gcc version 3.4.5 (mingw-vista special r3)
