• Can't place a breakpoint in asp.net master page file

  - by Tony_Henrich

  I have an MVC web application. I get an "Object reference not set to an instance of an object" error in line 16 below. It's a master page file. When I try to place a breakpoint in that line or anywhere in the file, I get a "this is not a valid location for a breakpoint" error. I have clicked on every line and I can't place a single breakpoint. I do have lines which have code only. How do I place a breakpoint in this file? Note: I can place breakpoints in code files. In some other aspx files, I can place a breakpoint in some code lines and some not. Does the inline code have to be in a special format to place a breakpoint? Using VS 2010 in Windows 7 64bit. Code: Line 14: <div id="<%= Model.PageWidth %>" class="<%= Model.PageTemplate %>"> Line 15: <div id="hd"> Line 16: <h1><a href="/"><%= Model.Workspace.Title %></a></h1> Line 17: <h2><%= Model.Workspace.Subtitle %></h2> Line 18: </div>

• Python, dictionaries, and chi-square contingency table

  - by rohanbk

  I have a file which contains several lines in the following format (word, time that the word occurred in, and frequency of documents containing the given word within the given instance in time): #inputfile <word, time, frequency> apple, 1, 3 banana, 1, 2 apple, 2, 1 banana, 2, 4 orange, 3, 1 I have Python class below that I used to create 2-D dictionaries to store the above file using as the key, and frequency as the value: class Ddict(dict): ''' 2D dictionary class ''' def __init__(self, default=None): self.default = default def __getitem__(self, key): if not self.has_key(key): self[key] = self.default() return dict.__getitem__(self, key) wordtime=Ddict(dict) # Store each inputfile entry with a <word,time> key timeword=Ddict(dict) # Store each inputfile entry with a <time,word> key # Loop over every line of the inputfile for line in open('inputfile'): word,time,count=line.split(',') # If <word,time> already a key, increment count try: wordtime[word][time]+=count # Otherwise, create the key except KeyError: wordtime[word][time]=count # If <time,word> already a key, increment count try: timeword[time][word]+=count # Otherwise, create the key except KeyError: timeword[time][word]=count The question that I have pertains to calculating certain things while iterating over the entries in this 2D dictionary. For each word 'w' at each time 't', calculate: The number of documents with word 'w' within time 't'. (a) The number of documents without word 'w' within time 't'. (b) The number of documents with word 'w' outside time 't'. (c) The number of documents without word 'w' outside time 't'. (d) Each of the items above represents one of the cells of a chi-square contingency table for each word and time. Can all of these be calculated within a single loop or do they need to be done one at a time? Ideally, I would like the output to be what's below, where a,b,c,d are all the items calculated above: print "%s, %s, %s, %s" %(a,b,c,d)

• using alias parameters in window command prompt

  - by freshWoWer

  Source:http://jpsoft.com/help/index.htm?alias.htm Aliases can use command line parameters or parameters like those in batch files. The command line parameters are numbered from %0 to %511. (%0 contains the alias name.) For example, the following alias will change directories, perform a command, and return to the original directory: alias in pushd %1 & %2$ & popd when i run the above, my command prompt gives error saying %1 * Unable to read value of alias * '%2' is not recognized as an internal or external command, operable program or batch file. 'popd`' is not recognized as an internal or external command, operable program or batch file. if you use double quote instead, alias in "pushd %1 & dir & popd" it doesn't interprets the %1 when you execute the alias C:\abc\defalias Dumping all defined aliases for CMD.EXE. in =pushd %1 & dir & popd alias def wont work ---------EDIT------------ let me try some sample output with a simple echo alias D:\abc\defalias /? Usage: ALIAS [-v] [-p programName] [-f filespec] [ ] [-v] means verbose output. [-d] means delete aliases. [-p programName] specifies which image file name these alias definitions are for. Default is CMD.EXE [-f filespec] specifies a file which contains the alises. C:\Office\dev15alias out 'echo %1' %1' * Unable to read value of alias * C:\Office\dev15alias out backtick echo %1 backtick %1` * Unable to read value of alias * C:\Office\dev15alias out "echo %1" C:\Office\dev15alias Dumping all defined aliases for CMD.EXE. out =echo %1 C:\Office\dev15out abc %1 C:\Office\dev15alias out echo %1 %1 * Unable to read value of alias * C:\Office\dev15out abc ECHO is on. Problem is, both single quote and back tick produces error, while double quote wont treat %1 as variable parameter

• custom wordpress page

  - by sharon

  I'd like to implement a custom post retrieval page in wordpress. Basically, I'm using AJAX to call this page that will be passed a post ID and retrieve certain data from that post. Note: please don't mistake this as a template question. I do not want a template for one single page -- I am looking to make this page query multiple different posts based on postID and return certain data from that post. So I tried creating a page <?php $args=array( 'p'=>'77' ); $friends = new WP_Query($args); ?> <?php if ($friends->have_posts()) : the_post(); ?> <?php the_title(); ?> <?php the_content(); ?> <?php else: ?> <p>Sorry, no posts are available.</p> <?php endif; ?> But this does not work since it is not loading in the wp functions to handle the query. Thanks in advance for any help!

• displaying music current time & duration from AVFoundation

  - by msb

  I have a view-based iphone application that has a single play-pause button that plays an mp3 file. At the time of invoking my doPlayPauseButton() method, I 'd like to show the current time and total duration of this mp3 through the AVAudioPlayer instance I've created, called myAudioPlayer. I have placed two labels at the UI and i'm trying to assign the currentTime and duration properties to these label when the playing begins but my attempts have failed. Here's my play/pause loop, any help would be appreciated: -(IBAction) doPlayPauseButton:(UIButton *)theButton { if(myAudioPlayer.playing) { [myActivityIndicatorView stopAnimating]; myActivityIndicatorView.hidden = YES; //I think I need a myAudioPlayer.currentTime call of some sort for my labels. [myAudioPlayer pause]; [theButton setTitle:@"Play" forState:UIControlStateNormal]; [myTimer invalidate]; } else { [myActivityIndicatorView startAnimating]; myActivityIndicatorView.hidden = NO; myTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(doTimer) userInfo:nil repeats:YES]; [myAudioPlayer play]; [theButton setTitle:@"Pause" forState:UIControlStateNormal];

• Find optimal/good-enough strategy and AI for the game 'Proximity'?

  - by smci

  'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal algorithm then b) how to build an AI. Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the insane branching factor (20^120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

• Optimizing PHP require_once's for low disk i/o?

  - by buggedcom

  Q1) I'm designing a CMS (-who isn't!) but priority is being given to caching. Literally everything is cached. DB rows, DB id queries, Configuration data, processed data, compiled templates. Currently it has two layers of caching. The first is a opcode cache or memory cache such as apc, eaccelerator, xcache or memcached. If an entry is not found in there it is then searched for in the secondary slow cache, ie php includes. Are the opcode caches actually faster than doing a require_once to a php file with a var_export'd array of data in it? My tests are inconclusive as my development box (5.3 of XAMPP) keeps throwing errors installing any of the aforementioned programs. Q2) The CMS has numerous helper classes that are autoloaded on demand instead of loading all files. Mostly each has a require before it so no autoloading needs to take place, however this is not the question. Because a page script can have up to 50/60 helper files included I have a feeling that if the site was under pressure it would buckle because of all the i/o that this incurs. Ignore for the moment that there is output cache in place that would remove the need for what I am about to suggest, and also that opcode caches would render this moot. What I have tried to do is join all the helper files required for the scripts execution in one single file. This is achievable and works well, however it has a side effect of greatly increasing the memory usage dramatically even though technically the same code is being used. What are your thoughts and opinions on this?

• Duck type testing with C# 4 for dynamic objects.

  - by Tracker1

  I'm wanting to have a simple duck typing example in C# using dynamic objects. It would seem to me, that a dynamic object should have HasValue/HasProperty/HasMethod methods with a single string parameter for the name of the value, property, or method you are looking for before trying to run against it. I'm trying to avoid try/catch blocks, and deeper reflection if possible. It just seems to be a common practice for duck typing in dynamic languages (JS, Ruby, Python etc.) that is to test for a property/method before trying to use it, then falling back to a default, or throwing a controlled exception. The example below is basically what I want to accomplish. If the methods described above don't exist, does anyone have premade extension methods for dynamic that will do this? Example: In JavaScript I can test for a method on an object fairly easily. //JavaScript function quack(duck) { if (duck && typeof duck.quack === "function") { return duck.quack(); } return null; //nothing to return, not a duck } How would I do the same in C#? //C# 4 dynamic Quack(dynamic duck) { //how do I test that the duck is not null, //and has a quack method? //if it doesn't quack, return null }

• DIY intellisense on XPath - design approach? (WinForms app)

  - by Cheeso

  I read the DIY Intellisense article on code project, which was referenced from the Mimic Intellisense? question here on SO. I wanna do something similar, DIY intellisense, but for XPath not C#. The design approach used there makes sense to me: maintain a tree of terms, and when the "completion character" is pressed, in the case of C#, a dot, pop up the list of possible completions in a textfield. Then allow the user to select a term from the textfield either through typing, arrow keys, or double-click. How would you apply this to XPath autocompletion? should there be an autocomplete key? In XPath there is no obvious separator key like "dot" in C#. should the popup be triggered explicitly in some other way, let's say ctrl-. ? or should the parser try to autocomplete continuously? If I do the autocomplete continuously, how to scale it properly? There are 93 xpath functions, not counting overloads. I certainly don't want to popup a list of 93 choices. How do I decide when I've narrowed it enough to offer a useful lsit of possible completions? How to populate the tree of possible completions? For C#, it's easy: walk the type space via reflection. At a first level, the "syntax tree" for C# seems like a single tree, and the list of completions at any point depends on the graph of nodes you've traversed to that point. Typing System.Console. traverses to a certain node in that tree, and the list of completions is the set of child nodes available at that node in the tree. On the other hand, the xpath syntax seems like it is a "flatter" tree - function names, axis names, literals. Does this make sense? what have I not considered?

• Dynamically add User Controls to a Silverlight 4 page

  - by PilotBob

  I am building an iGoogle like "dashboard" for our application with silverlight 4. Each users dashboard (which snapins and their positions) will be stored in the database. Each snap in is a user control, for example... AwesomeSnapin.xaml. On the dashboard page in silverlight I am retrieving the users dashboard which is a collection of snapin objects which include the information on the snapin. I can store the name of the page or the class or whatever is needed. I have the following code which loops through the collection of snapins to add them to the dashboard page. In testing I have just hard coded a single snapin item. Here is the prototype code: foreach (var UserSnapin in op.Entities) { UserControl uc = new AmsiSL.eFinancials.BudgetCheck(); Canvas.SetLeft(uc, UserSnapin.PositionLeft); Canvas.SetTop(uc, UserSnapin.PositionTop); Layout.Children.Add(uc); MessageBox.Show(String.Format("Added {0}",UserSnapin.Snapin.Name)); } The above works fine... but of course adds the BudgetCheck snapin for every item that is defined for the users dashboard. Of course the messagebox is for debugging purposes only. How would I change line 3 of that to load the user control class (using classname or xaml path whichever is better) based on the data in the collection.

• JSP Document/JSPX: what determines how tabs/space/linebreaks are removed in the output?

  - by NoozNooz42

  I've got a "JSP Document" ("JSP in XML") nicely formatted and when the webpage is generated and sent to the user, some linebreaks are removed. Now the really weird part: apparently the "main" .jsp always gets all its linebreak removed but for any subsequent .jsp included from the main .jsp, linebreaks seems to be randomly removed (some are there, others aren't). For example, if I'm looking at the webpage served from Firefox and ask to "view source", I get to see what is generated. So, what determines when/how linebreaks are kept/removed? This is just an example I made up... Can you force a .jsp to serve this: <body><div id="page"><div id="header"><div class="title">... or this: <body> <div id="page"> <div id="header"> <div class="title">... ? I take it that linebreaks are removed to save on bandwidth, but what if I want to keep them? And what if I want to keep the same XML indentation as in my .jsp file? Is this doable? EDIT Following skaffman's advice, I took a look at the generated .java files and the "main" one doesn't have lots of out.write but not a single one writing tabs nor newlines. Contrary to that file, all the ones that I'm including from that main .jsp have lots of lines like: out.write("\t...\n"); So I guess my question stays exactly the same: what determines how tabs/space/linebreaks are included/removed in the output?

• Using of Templated Helpers in MVC 2.0 : How can use the name of the property that I'm rendering insi

  - by Andrey Tagaew

  Hi. I'm reviewing new features of ASP.NET MVC 2.0. During the review i found really interesting using Templated Helpers. As they described it, the primary reason of using them is to provide common way of how some datatypes should be rendered. Now i want to use this way in my project for DateTime datatype My project was written for the MVC 1.0 so generating of editbox is looking like this: <%= Html.TextBox("BirthDate", Model.BirthDate, new { maxlength = 10, size = 10, @class = "BirthDate-date" })%> <script type="text/javascript"> $(document).ready(function() { $(".BirthDate-date").datepicker({ showOn: 'button', buttonImage: '<%=Url.Content("~/images/i_calendar.gif") %>', buttonImageOnly: true }); }); </script> Now i want to use Template Helper, so i want to have above code once i type next sentence: <%=Html.EditorFor(f=>f.BirthDate) %> According to the manual I create DataTime.ascx partial view inside Shared/EditorTemplates folder. I put there above code and stacked with the problem. How can i pass the name of the property that I'm rendering with template helper? As you can see from my example, i really need it, since I'm using the name of the property to specify data value and parameter name that will be send during the POST requsest. Also, I'm using it to generate class name for JS calendar building. I tried to remove my partial class for template helper and made MVC to generate its default behavior. Here what it generated for me: <input type="text" value="04/29/2010" name="LoanApplicationDays" id="LoanApplicationDays" class="text-box single-line"> As you can see, it used the name of the property for "name" and "id" attributes. This example let me to presume that Template Helper knows about the name of the property. So, there should be some way of how to use it in custom implementation. Thanks for your help!

• How to deploy EJB on server?

  - by shekhar

  Hi, I am learning EJB3 from last few days. I have many questions regarding EJB, application servers and deployment of EJB. To start with, I have created one simple helloworld stateless session bean but I don't know how to deploy it on server. It has single bean class, bean interface and one servlet client. I have used eclipse to develop this project. None of the books that I read gives step by step details about how to put EJB on server and how to access those beans. I have JBoss 6 server and I also have JEE budle downloaded from sun website. Does this JEE bundle contains Glassfish server? or do I need to download it seperately? Can anyone please give me step by step details of how to put my bean and its client on server (JBoss or JEE)? and why do we need to include bean interface class in EJB client code? I mean either we need to keep client and bean in same package or if we keep them in seperate packages we need to import bean interfaces in client code. Am I right? Thanks and Regards, Chandrashekhar

• Best Way to automatically compress and minimize JavaScript files in an ASP.NET MVC app

  - by wgpubs

  So I have an ASP.NET MVC app that references a number of javascript files in various places (in the site master and additional references in several views as well). I'd like to know if there is an automated way, and if so what is the recommended approach, for compressing and minimizing such references into a single .js file where possible. Such that this ... <script src="<%= ResolveUrl("~") %>Content/ExtJS/Ext.ux.grid.GridSummary/Ext.ux.grid.GridSummary.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/ext.ux.rating/ext.ux.ratingplugin.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/ext-starslider/ext-starslider.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/ext.ux.dollarfield.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/ext.ux.combobox.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/ext.ux.datepickerplus/ext.ux.datepickerplus-min.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/SessionProvider.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ExtJS/TabCloseMenu.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ActivityViewer/ActivityForm.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ActivityViewer/UserForm.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ActivityViewer/SwappedGrid.js" type="text/javascript"></script> <script src="<%= ResolveUrl("~") %>Content/ActivityViewer/Tree.js" type="text/javascript"></script> ... could be reduced to something like this ... <script src="<%= ResolveUrl("~") %>Content/MyViewPage-min.js" type="text/javascript"></script> Thanks

• Collaborative filtering in MySQL ?

  - by user281434

  Hi I'm trying to develop a site that recommends items(fx. books) to users based on their preferences. So far, I've read O'Reilly's "Collective Intelligence" and numerous other online articles. They all, however, seem to deal with single instances of recommendation, for example if you like book A then you might like book B. What I'm trying to do is to create a set of 'preference-nodes' for each user on my site. Let's say a user likes book A,B and C. Then, when they add book D, I don't want the system to recommend other books based solely other users experience with book D. I wan't the system to look up similar 'preference-nodes' and recommend books based on that. Here's an example of 4 nodes: User1: 'book A'->'book B'->'book C' User2: 'book A'->'book B'->'book C'->'book D' user3: 'book X'->'book Y'->'book C'->'book Z' user4: 'book W'->'book Q'->'book C'->'book Z' So a recommendation system, as described in the material I've read, would recommend book Z to User 1, because there are two people who recommends Z in conjuction with liking C (ie. Z weighs more than D), even though a user with a similar 'preference-node', User2, would be more qualified to recommend book D because he has a more similar interest-pattern. So does any of you have any experience with this sort of thing? Is there some things I should try to read or does there exist any open source systems for this? Thanks for your time! Small edit: I think last.fm's algorithm is doing exactly what I my system to do. Using the preference-trees of people to recommmend music more personally to people. Instead of just saying "you might like B because you liked A"

• Passing custom Python objects to nosetests

  - by Rob

  I am attempting to re-organize our test libraries for automation and nose seems really promising. My question is, what is the best strategy for passing Python objects into nose tests? Our tests are organized in a testlib with a bunch of modules that exercise different types of request operations. Something like this: testlib \-testmoda \-testmodb \-testmodc In some cases the test modules (i.e. testmoda) is nothing but test_something(), test_something2() functions while in some cases we have a TestModB class in testmob with the test_anotherthing1(), test_anotherthing2() functions. The cool thing is that nose easily finds both. Most of those test functions are request factory stuff that can easily share a single connection to our server farm. Thus we do a lot of test_something1(cnn), TestModB.test_anotherthing2(cnn), etc. Currently we don't use nose, instead we have a hodge-podge of homegrown driver scripts with hard-coded lists of tests to execute. Each of those driver scripts creates its own connection object. Maintaining those scripts and the connection minutia is painful. I'd like to take free advantage of nose's beautiful discovery functionality, passing in a connection object of my choosing. Thanks in advance! Rob P.S. The connection objects are not pickle-able. :(

• How to best show progress info when using ADO.NET?

  - by Yadyn

  I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

• Use $_FILES on a page called by .ajax

  - by RachelD

  I have two .php pages that I'm working with. Index.php has a file upload form that posts back to index.php. I can access the $_FILES no problem on index.php after submitting the form. My issue is that I want (after the form submit and the page loads) to use .ajax (jQuery) to call another .php file so that file can open and process some of the rows and return the results to ajax. The ajax then displays the results and recursively calls itself to process the next batch of rows. Basically I want to process (put in the DB etc) the csv in chunks and display it for the user in between chunks. Im doing it this way because the files are 400,000+ rows and the user doesnt want to wait the 10+ min for them all to be processed. I dont want to move this file (save it) because I just need to process it and throw it away and if a user closes the page while its processing the file wont be thrown away. I could cron script it but I dont want to. What I would really like to do is pass the (single) $_FILES through .ajax OR Save it in a $_POST or $_SESSION to use on the second page. Is there any hope for my cause? Heres the ajax code if that helps: function processCSV(startIndex, length) { $.ajax({ url: "ajax-targets/process-csv.php", dataType: "json", type: "POST", data: { startIndex: startIndex, length: length }, timeout: 60000, // 1000 = 1 sec success: function(data) { // JQuery to display the rows from the CSV var newStart = startIndex+length; if(newStart <= data['csvNumRows']) { processCSV(newStart, length); } } }); } processCSV(1, 2); }); P.S. I did try this Passing $_FILES or $_POST to a new page with PHP but its not working for me :( SOS.

• Android - Linear Layout arrangement, not positioning as expected

  - by Arun

  The following is my code. I want an interface where I have a single line textbox, a multiline textbox with 2 buttons below. I want the multiline textbox to occupy all the space available after rendering the buttons and textbox. For this I created two LinearLayouts inside the main layout. The first one has vertical orientation with layout_width set to fill_parent. The second one is horizontal with fill_parent again. The first one has a textbox for which I have set the layout_height to fill parent. The second one has two textboxes OK and Cancel. When I run this application I get the UI, but the Buttons are very small (about 5px in height). I have to set the button height manually. What am I doing wrong here. I don't want to hard code the button height. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Name"></TextView> <EditText android:layout_width="fill_parent" android:layout_height="wrap_content"></EditText> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Contents"></TextView> <EditText android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="top" /> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1"> <Button android:id="@+id/okbutt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="OK" android:layout_weight="1" /> <Button android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Cancel" android:layout_weight="1" /> </LinearLayout> Thanks, Arun

• How to Manage project in this scenario

  Hi All, I am working on a web application which has got good amount of static or pre-login pages. These pages can have some simple forms as well where we would like to capture the visitor's details. Post login, I have got my main application. I am confused about the development and deployment architecture of my application. Post login part of my application has a release cycle of 1-2 months while pre-login pages are to be updated on a weekly basis. It is difficult to make a release of pre-login pages as the overall war also contains post-login application & which sometimes is not release ready. Currently, I have got both these parts bundled in the single war project. Please help me by letting me know the best practices whereby I can achieve following: Manage the releases of these two parts independently. I am using Maven. So is there a way I can share the resources, such as CSS, images etc between these two parts. Header and footer of my application is going to be same on pre-login & post-login pages. I was thinking of deploying these apps as two war files in my tomcat container. But then how will I manage the common resources like Css, images etc. Rgds Vijay

• SqlBackup from my client app

  - by Robbert Dam

  I have an client app that runs on several machines, and connects to a single SQL database. On the client app, the user has the possiblity to use a local SQL (CE) database or connect to a remote SQL database. There is also a box where a backup location can be set. For the backup of the remote SQL database I use the following code: var bdi = new BackupDeviceItem(backupFile, DeviceType.File); var backup = new Backup { Database = "AppDb", Initialize = true }; backup.Devices.Add(bdi); var server = new Server(connection); backup.SqlBackup(server); When developing my application, I wasn't aware that the given backupFile is written on the machine where the SQL server runs! And not on the client machine. What I want is "dump" all the data from my database to a local file. (Why? Because users may enter a network location in the "backup location" box, and backing up SQL immediately to a network location fails. So need to write local first and then copy to the network in that case.) I there an alternative to the method above?

• Remove accents from a JSON response using the raw content.

  - by Pentium10

  This is a follow up of this question: Remove accents from a JSON response. The accepted answer there works for a single item/string of a raw JSON content. But I would like to run a full transformation over the entire raw content of the JSON without parsing each object/array/item. What I've tried is this function removeAccents($jsoncontent) { $obj=json_decode($jsoncontent); // use decode to transform the unicode chars to utf $content=serialize($obj); // serialize into string, so the whole obj structure can be used string as a whole $a = 'ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûýýþÿRr'; $b = 'aaaaaaaceeeeiiiidnoooooouuuuybsaaaaaaaceeeeiiiidnoooooouuuyybyRr'; $content=utf8_decode($content); $jsoncontent = strtr($content, $a, $b); // at this point the accents are removed, and everything is good echo $jsoncontent; $obj=unserialize($jsoncontent); // this unserialization is returning false, probably because we messed up with the serialized string return json_encode($obj); } As you see after I decoded JSON content, I serialized the object to have a string of it, than I remove the accents from that string, but this way I have problem building back the object, as the unserialize stuff returns false. How can I fix this?

• Glassfish: Defining Custom JNDI Names for Session Beans

  - by Adeel Ansari

  Background: Want to use GF3 in development, where as actual SIT, UAT, and production is using WAS. Problem: With the remote session beans everything is good to go, as GF3 gives a non-standard JNDI name, which is same as what WAS suggests, i.e. an absolute class name. Now for the local session beans WAS use the same absolute class name but with the prefix, i.e. ejblocal:. Whereas GF3 doesn't give any non-standard JNDI name for local session beans. GF3 came up with only portable name, java:global/..I need to find a way so I can use the same names for both. I am using EJB 3.0, WAS 7.9, and Glassfish 3. Don't have any xml confiuration for ejbs. Using Spring to inject the bean in Struts2 actions. With remote interfaces both servers are okay and agreed on a single convention, but for locals they differ. Is there any solution for this? Or just sun-ejb-jar.xml will solve it? Thanks.

• How can I display multiple django modelformset forms in a grouped fieldsets?

  - by JT

  I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of course, is that each 'form' must be rendered together in the appropriate fieldset. For example I want my template to produce something like this: <fieldset> <label for="id_base-0-desc">Home Base Description:</label> <input id="id_base-0-desc" type="text" name="base-0-desc" maxlength="100" /> <label for="id_likes-0-icecream">Want ice cream?</label> <input type="checkbox" name="likes-0-icecream" id="id_likes-0-icecream" /> </fieldset> <fieldset> <label for="id_base-1-desc">Home Base Description:</label> <input id="id_base-1-desc" type="text" name="base-1-desc" maxlength="100" /> <label for="id_likes-1-icecream">Want ice cream?</label> <input type="checkbox" name="likes-1-icecream" id="id_likes-1-icecream" /> </fieldset> I am using a loop like this to process the results (after form validation) base_models = base_formset.save(commit=False) like_models = like_formset.save(commit=False) for base_model, likes_model in map(None, base_models, likes_models): which works as I'd expect (I'm using map because the # of forms can be different). The problem is that I can't figure out a way to do the same thing with the templating engine. The system does work if I layout all the base models together then all the likes models after wards, but it doesn't meet the layout requirements. EDIT: Updated the problem statement to be more clear about what exactly I'm processing (I'm processing models not forms in the for loop)
