• Client Profile Application prerequisites

  - by Carlo

  One last question about Client Profile installation. I downloaded the Microsoft .NET Framework Client Profile Online Installer because we want to put it in the installation CD because our end user might not have either .net framework 3.5 or internet. So we want to be able to handle both cases. In the prerequisites I'm able to select the location of where the file will be, but I don't know where it should be. I want to be able to somehow put the path of the cd, something like d:\ProductName\Prerequisites\DotNetFx35ClientSetup.exe so it can get it and install it from there. Does anyone have an idea of how this can be achieved? Thank you. Here's the prerequisites window:

• How to switch iostream from binary to text mode and vice versa?

  - by Mad Fish

  I want to read both formatted text and binary data from the same iostream. How can I do that? Why? Imagine this situation: You have different resources, and resource loaders for them, that take a std::istream as a parameter. And there are a "resource source" that provides these streams. Resources can be both text and binary and I need to handle both cases with resource loaders. Or other situation: Image that you have an archive with resources of mixed types. How can I get a text stream from inside the binary archive stream?

• asp:QueryStringParameter and empty query string parameter

  - by abatishchev

  I haveasp:GridView displaying client requests using asp:SqlDataSource. I want to limit displayed information by client: View.aspx has to display everything, View.aspx?client=1 has to display only requests from client ID #1. So I'm using <asp:QueryStringParameter Name="client" QueryStringField="client" /> for query "EXEC getRequests @client". Everything works properly when some client is specified. But don't - if not. I tested my SP using SSMS - it works properly in both cases - when parameter is specified and when it isn't (NULL passed explicitly). What have I do?

• Is it good practice to initialize array in C/C++?

  - by sand

  I recently encountered a case where I need to compare two files (golden and expected) for verification of test results and even though the data written to both the files were same, the files does not match. On further investigation, I found that there is a structure which contains some integers and a char array of 64 bytes, and not all the bytes of char array were getting used in most of the cases and unused fields from the array contain random data and that was causing the mismatch. This brought me ask the question whether it is good practice to initialize the array in C/C++ as well, as it is done in Java?

• Android: how to update UI dynamically?

  - by pandre

  I have an Android app and I need to change UI dynamically: ex: when user presses a button, I want to change the current activity's views and, as in some cases there are a lot of views involved, I need to display a ProgressDialog. I have been using an AsyncTask, but I think that it is not the best solution, because AsyncTask's doInBackground runs a different thread, so I can't update UI from there - I have to use runOnUiThread, which runs the code in the UI Thread, but freezes the progress dialog that is shown. I guess there should be more people with similar issues, as updating UI while displaying a ProgressDialog seems to be something done regularly by applications. So does anyone have a solution to this?

• Controlling read and write access width to memory mapped registers in C

  - by srking

  I'm using and x86 based core to manipulate a 32-bit memory mapped register. My hardware behaves correctly only if the CPU generates 32-bit wide reads and writes to this register. The register is aligned on a 32-bit address and is not addressable at byte granularity. What can I do to guarantee that my C (or C99) compiler will only generate full 32-bit wide reads and writes in all cases? For example, if I do a read-modify-write operation like this: volatile uint32_t* p_reg = 0xCAFE0000; *p_reg |= 0x01; I don't want the compiler to get smart about the fact that only the bottom byte changes and generate 8-bit wide read/writes. Since the machine code is often more dense for 8-bit operations on x86, I'm afraid of unwanted optimizations. Disabling optimizations in general is not an option.

• Are MongoDB and CouchDB perfect substitutes?

  - by raoulsson

  I haven't got my hands dirty yet with neither CouchDB nor MongoDB but I would like to do so soon... I also have read a bit about both systems and it looks to me like they cover the same cases... Or am I missing a key distinguishing feature? I would like to use a document based storage instead of a traditional RDBMS in my next project. I also need the datastore to handle large binary objects (images and videos) automatically replicate itself to physically separate nodes rendering the need of an additional RDBMS superfluous Are both equally well suited for these requirements? Thanks!

• When are C++ macros beneficial?

  - by Motti

  The C preprocessor is justifiably feared and shunned by the C++ community. In-lined functions, consts and templates are usually a safer and superior alternative to a #define. The following macro: #define SUCCEEDED(hr) ((HRESULT)(hr) >= 0) is in no way superior to the type safe: inline bool succeeded(int hr) { return hr >= 0; } But macros do have their place, please list the uses you find for macros that you can't do without the preprocessor. Please put each use-cases in a seperate answer so it can be voted up and if you know of how to achieve one of the answers without the preprosessor point out how in that answer's comments.

• Deploying BlackBerry Applications Across Environments

  - by sethxian

  Has anyone come up with a good solution for deploying BlackBerry applications across different environments? My example is storing URLs and Authentication information in code. In most cases, a developer is going to have a different set of URL's to test against when developing the application vs what the end user is going to hit. The idea is when I go to build for production, I have something swap out the environment settings for the target environment vs manually replacing environment specific code each time. I am currently using eclipse. The only thought I've come up with so far would be to use a resource with encrypted values and have that swap when I run my build. Any ideas?

• IE6 and IE7 Standalone: What do they render differently?

  - by yar

  It's common knowledge on SO (see this question) that to run IE6 and IE7 you need a Windows box (or virtual box) with only those apps installed. I doubt this is true (they are the real versions, I think). The two browsers I'm interested in are: Standalone IE6 from the MultipleIEs install Standalone IE7 also from Tredosoft (but published elsewhere) These two plus a "real" install of IE8 give you three IE versions in one Windows install. We all know that "You're out of luck if you're trying to run them all reliably in one VM," but can someone please show me JS, CSS, or HTML (or a plugin, etc.) that does not work on the standalone versions as it should? Downvoters: I'm fixing the question so that it's less aggressive, but since there are no comments I don't know what you don't like about this question. Also: I have ALL the test cases set up (IE6, IE7 and IE8, as well as the standalone versions) so if anybody has any code they want me to test, I can do that.

• Order words by number of letters, then place words neatly

  - by bmaster

  I have a list of words in javascript similar to this: var words = ["mine", "minute", "mist", "mixed", "money", "monkey", "month", "moon", "morning", "mother", "motion", "mountain", "mouth", "move", "much", "muscle", "music", "nail", "name", "narrow", "nation", "natural", "near", "necessary", "neck", "need", "needle", "nerve", "net", "new", "news", "night"]; The words can be 1-25? letters long. I have a div id="words", with a set width of 700px (but I might change it from this). Using css/javascript/jquery, how can I make it: Order the words by number of letters Place the words inside the div tag, left to right, but so that there are no gaps at the right edge of the words div, and there is even spacing between words on a line. Each word should have a border around it and a background. Like this: |reallylongwordssdf shorterwordfdf dfsdfsdfsdf sdfsdfsdf| |sdfsdfsdf sdffsdop sdfjpogs sdfsds dfsdsd dfsdsd dfsdsd| I really have no idea where to begin with this. Perhaps I could manage to write code to order the words by number of letters, but after that, I'd be stuck. Edit: I forgot to add, the words must be links.

• Symfony 1.3: different form filters generated

  - by user248959

  Hi, i have this class in rs1/lib/filter/doctrine/FelizFormFilter.class.php <?php /** * Feliz filter form. * * @package rs * @subpackage filter * @author Your name here * @version SVN: $Id: sfDoctrineFormFilterTemplate.php 23810 2009-11-12 11:07:44Z Kris.Wallsmith $ */ class FelizFormFilter extends BaseFelizFormFilter { public function configure() { } } and this in rs2/lib/filter/doctrine/FelizFormFilter.class.php <?php /** * Feliz filter form. * * @package filters * @subpackage Feliz * * @version SVN: $Id: sfDoctrineFormFilterTemplate.php 11675 2008-09-19 15:21:38Z fabien $ */ class FelizFormFilter extends BaseFelizFormFilter { public function configure() { } } Both were generated using "php symfony doctrine:build --all --and-load" and the version of symfony is 1.3.4 in both. This is the schema of both cases: Feliz: columns: name: string(20) Could you tell me why are different? One more thing in Eclipse: when i go with the mouse pointer to the word "BaseFelizFormFilter", in the second case (rs2) the yellow window with the information about the class is showed, but in the first case that yellow popup is not showed. Why? Javi

• Undefined behaviour with non-virtual destructors - is it a real-world issue?

  - by Roddy

  Consider the following code: class A { public: A() {} ~A() {} }; class B: public A { B() {} ~B() {} }; A* b = new B; delete b; // undefined behaviour My understanding is that the C++ standard says that deleting b is undefined behaviour - ie, anything could happen. But, in the real world, my experience is that ~A() is always invoked, and the memory is correctly freed. if B introduces any class members with their own destructors, they won't get invoked, but I'm only interested in the simple kind of case above, where inheritance is used maybe to fix a bug in one class method for which source code is unavailable. Obviously this isn't going to be what you want in non-trivial cases, but it is at least consistent. Are you aware of any C++ implementation where the above does NOT happen, for the code shown?

• NHibernate cascade and generated guid ids - why are they not generated for the children on save?

  - by asgerhallas

  I do the following: var @case = new Case { Name = "test" }; // User is persistent and loaded in the same session User.AddCase(@case); // sets @case.User = User too Session.Update(User); response.CaseId = @case.Id; The cascade on User.Cases is set to All. But @case.Id is not set until the transaction is committed. Is that expected behavior? I would very much like to get the Id before committing. Can it be done?

• Generate a matrix of all possible outcomes for throwing n dice (ignoring order)

  - by Brani

  In cases where order does matter, it's rather easy to generate the matrix of all possible outcomes. One way for doing this is using expand.grid as shown here. What if it doesn't? If I'm right, the number of possible combinations is (S+N-1)!/S!(N-1)!, where S is the number of dice, each with N sides numbered 1 through N. (It is different from the well known combinations formula because it is possible for the same number to appear on more than one dice). For example, when throwing four six-sided dice, N=6 and S=4, so the number of possible combinations is (4+6-1)!/4!(6-1)! = 9!/4!x5! = 126. How can I generate a matrix of these 126 possible outcomes? Thank you.

• flex positioning a button within a panel

  - by pfunc

  All I'm trying to do is place a button inside of a panel, rotate that button (so it is vertical) and place it on the edge of the panel. I can;t seem to do this correctly. Here is my code: <mx:Panel id="weekList" width="260" height="100%" x="-500" title="Weeks" > <mx:List id="weekButtonList" width="260" borderVisible="false" contentBackgroundAlpha="0" dataProvider="{_data.mappoints.week.@number}" itemClick="onWeekClick(event);" > <mx:itemRenderer> <mx:Component> <mx:Button buttonMode="true" right="20" width="260" height="50" label="Week {data}" /> </mx:Component> </mx:itemRenderer> </mx:List> <mx:HBox id="closeButtonHolder" rotation="90" width="100" > <mx:Button label="OPEN" click="weekListToggle()" /> </mx:HBox> </mx:Panel> If you look at the part of the script you will see I am trying to rotate it and move it to the left. I am just trying to move it somewhere, and nothing is working. Also, the text seems to dissapear when I rotate it on a 90% axis. Anyone know what I can do for this?

• C#: How to constuct a variable from another variables

  - by ozzwanted

  How to construct new variable in C#. I mean, to have sth like this public void updateXXX(string endingOfVariable, int newValue) { this.textBox_{endingOfVariable} = newValue; } This is implemented in Php: $a = 'var'; $b = 'iable'; $variable = 'var'; echo ${$a.$b}; But maybe it is possible in C#. The problem is that - I created ~500 textBoxes in C# Windows Form, and if I want to set a value, I need to build a switch() {case:; } statment with 500's cases.

• Trying to create fields based on a case statement

  - by dido

  I'm having some trouble with the query below. I am trying to determine if the "category" field is A, B or C and then creating a field based on the category. That field would sum up payments field. But I'm running into error saying "incorrect syntax near keyword As". I am creating this in a SQL View. Using SQL Server 2008 SELECT r.id, r.category CASE WHEN r.category = 'A' then SUM(r.payment) As A_payments WHEN r.category = 'B' then SUM(r.payment) As B_payments WHEN r.category = 'C' then SUM(r.payment) As C_payments END FROM r_invoiceTable As r GROUP BY r.id, r.category I have data where all of the above cases should be executed because the data that I have has A,B and C Sample Data- r_invoiceTable Id --- Category ---- Payment 222 A ---- 50 444 A ---- 30 111 B ---- 90 777 C ---- 20 555 C ---- 40 Desired Output A_payments = 80, B_payments = 90, C_payments = 60

• Listing C/C++ functions (Code analysis in Unix)

  - by Jond

  Whether we're maintaining unfamiliar code or checking out the implementation details of an Apache module it can help if we can quickly traverse the code and build up an overview of what we're looking at. Grep serves most of my daily needs but there are some cases where it just wont do. Here's a common example of how it can help. To find the definition of a PHP function I'm interested in I can type this at the command line: grep -r "function myfunc" . This could be adapted very quickly to C or C++ if we know the return type, but things become more complicated if, say, I want to list every method that my class provides: grep "function " ./src/mine.class.php Since there's no single keyword that denotes a function or method in C++ and because it's generally more complex syntax, I think I'd need some kind of static code analysis tool, smart use of the C Preprocessor or blind faith the coder followed strict code guidelines (# of whitespace, position of curlies etc) to get these sorts of results. What would you recommend? p.s. be nice, this is my first post ;-) :p

• How to enforce lazy loading of entities on certain conditions

  - by Samuel

  We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

• Java: JGraphT: Iterate through nodes

  - by Rosarch

  I'm trying to iterate through all nodes, so I can print them out for graphviz. What is the best way to do that using the JGraphT library? public static void main(String[] args) { UndirectedGraph<String, DefaultEdge> g = new SimpleWeightedGraph<String, DefaultEdge>(DefaultEdge.class); String odp = "ODP"; String cck = "CCK"; String mfe = "MFE"; g.addVertex(odp); g.addVertex(cck); g.addVertex(mfe); g.addEdge(odp, cck); g.addEdge(odp, mfe); } Also, how do I add edge weights? Edit: This seems to work pretty well. But is there a better way? Set<DefaultEdge> edges = g.edgeSet(); for (DefaultEdge e : edges) { gv.addln(String.format("\"%s\" -> \"%s\"", g.getEdgeSource(e), g.getEdgeTarget(e))); }

• Arguments against Create or Update

  - by Nix

  Recently someone stated that they thought all Creates should be CreateOrUpdates. Instinctively i thought bad, but now I am trying to find out if I have any grounds. Situation interface IService{ void Create(Object a); void Update(Object a); } or interface IService{ void CreateOrUpdate(Object a); } My first thought is if you implemented everything CreateOrUpdate then you have no control if someone accidentally sends you wrong data, or concurrency issues where someone changes a "primary" field right before you call update.... But if you remove those cases, are there any other cons?

  what is a best practice in cases such as this one: try { // do something } catch (SpecificException ex) { Response.Redirect("~/InformUserAboutAn/InternalException/"); } the warning i get is that ex is never used. however all i need here is to inform the user, so i don't have a need for it. do i just do: try { // do something } catch { Response.Redirect("~/InformUserAboutAn/InternalException/"); } somehow i don't like that, seems strange!!? any tips? best practices? what would be the way to handle this. thnx

• How to limit the number of post values on UpdatePanel ?

  - by Aristos

  I have notice that the UpdatePanel post every field included on the form on every trigger. But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent. When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data. So I see that a lot of traffic is happened this way. So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ? Thank you in advanced.

• using JDBC with persistence.xml

  - by moshe shamy

  I am building a framework that manage the access to the database. the framework getting tasks from the user and handle a connection pooling that manage the access to the database. the user just send me SQL commands. One of the feature that i would like to support is working with JPA, in this case i will provide entity manager. in some cases i would like to provide JDBC access as well as JPA access. the arguments for the database are written in XML file. so for JPA i need to write the property in persistence.xml so it will be not so smart to write again the same arguments for JDBC. do you know if i can get the arguments of the database from persistence.xml, do you know if there is a source code that do it. or should i parse persistence.xml by myself?
