• Get text when enter is pressed in a text box in wxPython

  - by Sam

  I have a (single line) TextCtrl. The user types data into this. When they press enter, the contents of the box need to be extracted so they can be processed. I can't figure out how to catch enter being pressed. According to the docs, with the style wx.TE_PROCESS_ENTER set on my TextCtrl, it should generate a wx.EVT_COMMAND_TEXT_ENTER event when enter is pressed in the box, which I could then catch. However, wx.EVT_COMMAND_TEXT_ENTER seems not to exist (I get "module has no attribute EVT_COMMAND_TEXT_ENTER), so I'm a bit stuck. Googling just gets a couple of hits of people complaining wx.EVT_COMMAND_TEXT_ENTER doesn't work, so I guess I need another way of doing it.

• Need generated UML diagrams for C++ plugin modules

  - by archer1742

  I need various UML diagrams (sequence/collaboration, class, package, and system component) from some C++ files. However, these files are plugins in a larger programming framework. I have tried generating UML from Rational Rose 7 (2002 version), but I am not very experienced and I am unsure if RR simply cannot produce the diagram, I am doing something wrong, or the diagrams are not rendering correctly because the source files are plugins instead of standalone programs. I have also tried Star Modeler with little success and there seem to be no tutorials on how to generate these models. Is there a simple, bulletproof way to get UML diagrams for C++ files?

• .click() callback references local variable from the calling method instead of copying by value

  - by Eric Freese

  The following jQuery Javascript code is included on an otherwise empty page. $(function() { for (var i = 0; i < 10; i++) { element = $('<div>' + i + '</div>'); element.click(function() { alert(i); }); $('body').append(element); } }); The desired behavior is that this code should generate 10 div elements numbered from 0 to 9. When you click on a div element, an alert popup will show the number of the div element you clicked on (i.e. if a user clicks on the div element labeled '4', the alert popup should show the number 4). The alert popup instead shows the number 10 regardless of which div element is clicked on. How can I modify this code to make it behave in the desired way?

• What technology should I use for a complex report?

  - by SeaDrive

  I have a task to generate reports from a Visual Studio C# application. This is a replacement (caused by new requirements) for a program written using the built-in implementation of Crystal Reports. Although workable, it was far from ideal. The reports have conditional content (If type=1, print this, if type=2 print that.) Crystal does not adjust spacing dynamically and the various pieces were not the same length making for some unprofessional-looking spacing. I had thought of generating the reports in HTML, which would be feasible, but I'm concerned that you lose a degree of control, and I may be asked, e.g. to "move this up a bit" or similar which may be tricky. I'm not either a Crystal guru or an HTML guru. What other reporting technologies are available that would make it easy to drop in parts of different sizes, do table layouts, etc.?

• Under what circumstances would a Ruby $LOAD_PATH be acquired from a parent process?

  - by Dr Nic

  In my cucumber scenarios, if I call rake db:schema:load within a target Rails app folder, I get the cucumber process's $LOAD_PATH and not the Rails app's own Gemfile/load path. I think this is very weird. The consequence is that I get the following error: no such file to load -- rails/all I can't reproduce it outside of my cucumber scenario. ruby -rubygems -e "system 'rake -T'" works normally - the 'rake -T' has the application's own Gemfile-based $LOAD_PATH; and doesn't generate the error above. Can anyone think why a child process (rake -T or rake db:schema:load or rails runner...; invoked by either system, exec, %x[...] or backtick; would start with the parent processes' $LOAD_PATH (from the cucumber scenario's Gemfile) instead of its own $LOAD_PATH (from the Rails app's Gemfile)?

• generating function arguments in java

  - by aloishis89

  I'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have: int number = 1 + (int)(Math.random() * ((12 - 1) + 1)); number = (int) Math.floor(number); String nextQuote = "javascript:wave" + number + "()"; mWebView.loadUrl(nextQuote); So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

• [ASP.NET] Generating images: Alternate font by User Agent (OS)

  - by sinni800

  Hello, I need to generate small images for certain parts of text. Those will have to fit into the text seamlessly. I know I can not make up for every browser font settings available, but how do I have to check for Linux, Mac and Windows users depending on the user agent? I want to use the right font (of the three "Verdana, Arial, Helvetiva") for the right user agent OS. So: How do I check for the OS? What do I have to compare to in the user agent? Where can I get the other two fonts. Does the Windows-included Verdana look the same as the one used on Linux (or, is it free anyway? I don't know much about fonts)? Where do I get Helvetica? Is it Mac OS licensed? Any code examples can be in either c# or VB.NET. I can read both. Thank you in advance.

• Visual Studio 2008 XML Documentation

  - by Pablo

  Hello, I can't seem to find the "Build" option under "Configuration Properties" folder in the Property Pages of my project. I've been looking everywhere trying to figure out how to do it. I followed the direations here: http://msdn.microsoft.com/en-us/magazine/cc302121.aspx More specifically here: http://msdn.microsoft.com/en-us/library/azt1z1eh.aspx ("To build the XML Documentation sample within Visual Studio" section) I want to generate XML comments for my project in the build, but my "Configuration Properties" window does not have "folders" or a "Build" option under it. I'm using Visual Studio Team System 2008, any ideas? EDIT - This is a website [project-less] and it is written in both C# and VB.NET. Do I need to download any tools? I found GhostDoc but that's not helping me very much.

• Facebook email Permission, oath2, doesnt work?

  - by Mathias Eklöf

  since the new Auth Dialog from Facebook (for my App & homepage), I cannot get the dialog to show that my homepage/app needs the users email when connection to my homepage/app. In the Auth-section of my app I've added "email" to the User & Friend Permissions. Also I've added it to the referal when someone clicks the "Login with facebook"-button. When someone clicks the Facebook-button, he/she redirects to a page which has the PHP-code with Facebook SDK PHP (latest). Here's how I generate the send-to-url for the dialog: $login_url = $facebook-getLoginUrl(array('req_perms' = 'email,publish_stream')); header("Location: ".$login_url); But when the Dialog pops up, the only permission request it does is "basic information". I need to request the Email. Am I stupid or is it a bug somehow? I've also recreated the App.

• Can Eclipse not hard-code ECLIPSE_HOME when exporting build.xml?

  - by stevex

  I have an Eclipse project that I'm attempting to set up to build both with Eclipse and externally with Ant. It seems like a good way to do this is to have Eclipse generate a build.xml file that I can then use with ant. I'd like to set it up so the build.xml can be regenerated from Eclipse whenever the need arises, which means no hand-editing the build.xml file. But Eclipse writes one entry in there that has a hard-coded path to a directory on my computer, which makes it unsuitable for checking in to a source repository. Specifically it's this entry that's the trouble: <property name="ECLIPSE_HOME" value="D:/Eclipse/Eclipse Galileo (3.5) SR1"/> Is there some way to have Eclipse not output this line, or to make it a relative reference or something that makes sense to check in?

• Does anyone use AODL in a real application?

  - by HyperQuantum

  We are currently using the Excel interop API in .NET to generate simple spreadsheet documents from a template. So we load the template first, insert some rows, fill in some data (dates, text, and numbers), and make Excel visible so that the user can print or save the document we just generated. But I'd like to get rid of the Excel dependency, and switch to the ODF format as well. Googling suggests AODL (C# libs for generating ODF docs) as the most obvious solution. But their last release is 1.3.0.0 BETA, and seems to be 3 years old. So I'm not sure if it's a good idea to depend on a potentially dead project... In that case, I'd need to find another solution. Any ideas? Or maybe someone could assure me that AODL is still alive?

• Enumerable.Range in and Expression and Entity Framework

  - by eka808

  I'm currently developping an expression method (used in linq to entity queries) who has to give me a daycount for a given period (start date and end date) decrementing this daycount if specials days are in the period. My idea was the following : Generate an enumerable with all the dates (and with Enumerable.Range) Make a .Where on this enumerable to remove the specials dates Like a MyEnumerable.Where(a = a != "20120101") After that, return a MyEnumerable.Count() I come with this code : return (p) => Enumerable .Range(1, 4) .Where(a => a != 20120101) .AsQueryable() .Count() I tried to cast as a list, as a queryable, both (like the example) and no way ! it doesn't work ! I always get this error : LINQ to Entities does not recognize the method 'System.Collections.Generic.IEnumerable`1[System.Int32] Range(Int32, Int32)' method, and this method cannot be translated into a store expression. Have you got an idea about that ? Using an enumerable is of course not mandatory, any working solutions is good ^^ Thank's by advance !

• Query to add a column depending of outcome of there columns

  - by Tam

  I have a user table 'users' that has fields like: id first_name last_name ... and have another table that determines relationships: user_id friend_id user_accepted friend_accepted .... I would like to generate a query that selects all the users but also add another field/column say 'network_status' that depends on the values of user_accepted and fiend_accepted. For example, if user_accepted is true friend_accepted is false I want the 'network_status' field to say 'request sent'. Can I possibly do this in one query? (I would prefer not to user if/else inside the query but if that's the only way so be it)

• How can an Android Service know that its not bound to any Activities

  - by tunneling

  I have an Android Service that I would like to keep running even after the last Activity has been popped off the stack, or the User has chosen to do something else. Essentially the Service is listening for changes on a remote server, and I would like to generate a Notification if and only if an Activity from the app isn't running(or visible). In other words, I don't want the Notifications to occur while the User is directly interacting with the app. In the case where the User is directly interacting with the app, the Service will notify the Activity and update appropriate UI elements based on the changes. I plan to implement this through the Observer pattern. How can the Service know if none of apps Activities are bound to it? Thanks, J

• .Net Round-trip Types

  - by Fujiy

  I making a method that generate a unique string key for some parameters. But the same key if call with same values. I just accept primitive types, string, DateTime, Guid, and Nullable(since I append types together, I can distinguish who is int and who is int?), because I can convert all to string without lost values or precision.(for float and double a use ToString("R"), to DateTime ToString("O")). Exists a easy way to know which types I can transform in strings without conflict? And how do this transform(how I said before, float, double and datetime have specific ways) Thanks

• Design guide-lines for writing a Typed SQL Statement API ?

  - by this. __curious_geek

  Last night I came up to sometihng intersting while designing my new project that brought me to ask this qustion here. My project is supposed to follow Table Gateway pattern using tradional ADO.Net datasets for data access. I don't want to write plain queries in my data-access classes. So I came up with an idea of writing a parser kindaa api that exposes objects and methods to generate queries on the move based on my domain objects. Later I want this api to hook up to my Business objects and provide Typed SQL generator api right on the business object instances. Any idea or references how can I do this ? This seems very wide to start with that I'm compelled take your opinions here. Does there anything already exists that can do this ?

• What Should be the Structure of a C++ Project?

  - by Ell

  I have recently started learning C++ and coming from a Ruby environment I have found it very hard to structure a project in a way that it still compiles correctly, I have been using Code::Blocks which is brilliant but a downside is that when I add a new header file or c++ source file, it will generate some code and even though it is only a mere 3 or 4 lines, I do not know what these lines do. First of all I would like to ask this question: What do these lines do? #ifndef TEXTGAME_H_INCLUDED #define TEXTGAME_H_INCLUDED #endif // TEXTGAME_H_INCLUDED My second question is, do I need to #include both the .h file and the .cpp file, and in which order. My third question is where can I find the GNU GCC Compiler that, I beleive, was packaged with Code::Blocks and how do I use it without Code::Blocks? I would rather develop in a notepad++ sort of way because that is what I'm used to in Ruby but since C++ is compiled, you may think differently (please give advice and views on that as well) Thanks in advance, ell.

• [MySQL, InnoDb] Rating place

  - by Pavel

  I'm trying to generate rating place table using following receipt http://stackoverflow.com/questions/1776821/assign-places-in-the-rating-mysql-php but my database is high loaded. I tried not to create table, but use MEMORY TABLE and update it using following SQL query insert into tops (uid) select uid from users order by exp desc; but got the following MySQL error Deadlock found when trying to get lock; try restarting transaction because there are too many queries until SQL select is being executed. How to solve this problem? P.S. CREATE TABLE tops as SELECT work almost fine except high server load... up to load average: 50 if tops are non-memory table. My table users has near 4.5 millions of rows. Thanks for any advices.

• How would you use version control for personal data, like a personal website?

  - by nn

  This is more a use-case question, but I generate static files for a personal website using txt2tags. I was thinking of maybe storing this information in a git repository. Normally I use RCS since it's simplest, and I'm only a single user. But there just seems to be a large trend of people using git/svn/cvs/etc. for personal data, and I thought this may also be a good way to at least learn some of the basics of the tool. Obviously most of the learning is done in an environment where you collaborate. So back to the question: how would you use use a version control system such as git, to manage a personal website?

• nodejs, mongodb - How do I operate on data from multiple queries?

  - by Ryan

  Hi all, I'm new to JS in general, but I am trying to query some data from MongoDB. Basically, my first query retrieves information for the session with the specified session id. The second query does a simple geospacial query for documents with a location near the specified location. I'm using the mongodb-native javascript driver. All of these query methods return their results in callbacks, so they're non-blocking. This is the root of my troubles. What I'm needing to do is retrieve the results of the second query, and create an Array of sessionIds of all the returned documents. Then I'm going to pass those to a function later. But, I can't generate this array and use it anywhere outside the callback. Does anyone have any idea how to properly do this? http://dpaste.org/wXiE/

• T-SQL - Is there a (free) way to compare data in two tables?

  - by RPM1984

  Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

• Errors when using a Ruby On Rails scaffold with a data type of interger

  - by bublebboy

  I am learning Ruby On Rails. I am on a shared hosting with Ruby version 1.8.1 and Rails version 2.3.10. I am working my way through a tutorial at http://railstutorial.org/chapters/a-demo-app?version=2.3#top and at one point in the tutorial it has me run: script/generate scaffold Micropost content:string user_id:interger The tutorial is using the default database, SQLite3. The command works and I use rake db:migrate to create the database. I can view the page listing the microposts (which is empty), but when I try to add a micropost (microposts/new) I get an error undefined method `user_id' for #<Micropost:0x7f710e4988e8> After doing some testing on my own it seems I experience the problem by using the data type of interger. While I understand that using a scaffold is not the best way of building a ruby on rails, I'm just beginning and would still like to know why I am experiencing this problem to help me better understand how rails works.

• Map a struts2 action result to a controller instead of a jsp

  - by Jim

  Hello, I'm working on on a site built using struts2. The vast majority of our targets generate xml, so mapping the result to a jsp page makes sense. A couple of our targets actually generated binaries. I'm wondering if there is a convenient way to say that the result should come from a servlet/controller instead of a jsp. Obviously this could be done by modifying the web.xml so the struts filter doesn't apply to those targets and mapping those targets as servlets, but this is non-ideal. Currently, the struts filter applies to the entire site, and we would like to keep it that way. Ideas? Thanks!

• Import Data from Excel Spreadsheet or CVS into MySQL

  - by Kelly Roper

  I have a spreadsheet which really has only one complicated table. I basically convert the spreadsheet to a cvs and use a groovy script to generate the INSERT scripts. However, I cannot do this with a table that has 28 fields with data within some of the fields on the spreadsheet that make importing into the CVS even more complicated. So the fields in the new CVS are not differentiated properly or my script has not accounted for it. Does anyone have any suggestions on a better approach to do this? Thanks.
