• how do you reuse a partial view with different ids

  - by oo

  i have a partial view with a dropdown in it. the code looks like this: <%=Html.DropDownListFor(x => Model.Exercises, new SelectList(Model.Exercises, "Id", "Name", Model.SelectedExercise), new { @id = "exerciseDropdown", @class = "autoComplete" })%> the issue is that i want to reuse this partial view in multiple places but i want to have a different id assigned to the control (instead of exerciseDropdown always) but on the outside i only have this . . <% Html.RenderPartial("ExerciseList", Model); %> is there anyway to pass in an id into a partial view. should i stick this into my view model as a seperate property "Model.ExerciseDropdown2" for example. is there a better way ?

• VBS Script for modifying multi-value Active Directory display specifier

  - by sh-beta

  Following the howto Extending the Active Directory Schema To Track Custom Info I'm able to setup a single-value schema attribute that is easily changeable via a context menu in ADUC. Multi-value schema attributes get considerably more complicated. Say (for the sake of argument) my value is "Projects" and each user may be a list as many projects as necessary. Following is a sad little script that will set Project to a single value: Dim oproject Dim oUser1 Dim temp1 Set oproject = Wscript.Arguments Set oUser1 = GetObject(oproject(0)) temp1 = InputBox("Project: " & oUser1.project & vbCRLF & vbCRLF & "Project") if temp1 <> "" then oUser1.Put "project",temp1 oUser1.SetInfo Set oUser1 = Nothing Set oproject = Nothing Set temp1 = Nothing WScript.Quit How can I modify this to allow, assign, and modify multiple values?

• streaming XML serialization in .net

  - by Luca Martinetti

  Hello, I'm trying to serialize a very large IEnumerable<MyObject> using an XmlSerializer without keeping all the objects in memory. The IEnumerable<MyObject> is actually lazy.. I'm looking for a streaming solution that will: Take an object from the IEnumerable<MyObject> Serialize it to the underlying stream using the standard serialization (I don't want to handcraft the XML here!) Discard the in memory data and move to the next I'm trying with this code: using (var writer = new StreamWriter(filePath)) { var xmlSerializer = new XmlSerializer(typeof(MyObject)); foreach (var myObject in myObjectsIEnumerable) { xmlSerializer.Serialize(writer, myObject); } } but I'm getting multiple XML headers and I cannot specify a root tag <MyObjects> so my XML is invalid. Any idea? Thanks

• synchronized block in JSP tag class

  - by Sudhakar

  Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())

• Algorithmic trading software safety guards

  - by Adal

  I'm working on an automatic trading system. What sorts of safe-guards should I have in place? The main idea I have is to have multiple pieces checking each other. I will have a second independent little process which will also connect to the same trading account and monitor simple things, like ensuring the total net position does not go over a certain limit, or that there are no more than N orders in 10 minutes for example, or more than M positions open simultaneously. You can also check that the actual open positions correspond to what the strategy process thinks it actually holds. As a bonus I could run this checker process on a different machine/network provider. Besides the checks in the main strategy, this will ensure that whatever weird bug occurs, nothing really bad can happen. Any other things I should monitor and be aware of?

• Data logged to a file; how do I rotate logs and how do I parse the data to not have 'gaps' in the da

  - by phidah

  I've got a web application that, for performance reasons, throws any data sent into a logfile. I've got two concerns with this approach: How do I best rotate logs, in order to not lose data? For each user session multiple requests are logged. Each request has a unique id so there is an easy way for me to tie the requests to the session. The problem is, however, that if I rotate the logs I risk ending up with one request in one log and another request in another log. How do I arrange my parsing in a way that allows me to parse all requests from a given session? I am willing to define a session timelimit, for example that the requests must, at maximum be 30 minutes apart. If I had a hourly log rotation at 00 minutes: What if the user made one request at 13:59 and one at 14:01 - The user would end up having requests in two different logs.

• Delete link to file without clearing readonly bit

  - by Joshua

  I have a set of files with multiple links to them. The files are owned by TFS source control but other links to them are made to them. How do I delete the additional links without clearing the readonly bit. It's safe to assume: The files have more than one link to them You are not deleting the name owned by TFS There are no potential race conditions You have ACL full control for the files The machine will not lose power, nor will your program be killed unless it takes way too long. It's not safe to assume: The readonly bit is set (don't set it if its not) You can leave the readonly bit clear if you encounter an error and it was initially set Do not migrate to superuser -- if migrated there the answer is impossible because no standard tool can do this.

• Best Version control for lone developer

  - by Stephen

  I'm a lone developer at the moment; please share you experiences on what is a good VC setup for a lone developer. My constraints are; I work on multiple machines and need to keep them synced up Sometimes I work offline I'm currently using Subversion(just the client to a remote server), and that is working ok. I'm interested in mecurial and git DVCS, but none of their use-cases make sense to my situation. EDIT: I've migrated my active development to Fossil http://www.fossil-scm.org/ after trialing it with a client. I really like the features to autosync my repositories(reducing accidental forks), the documentation support(both wiki and embedded/versioned) that supports my need to document the code and the project in different spaces, the easy to configure issue tracker, nice access control, skinnable web interface and helpful community.

• Change write-host output color based on foreach if elseif outcome in Powershell

  - by Emo

  I'm trying to change the color of write-host output based on the lastrunoutcome property of SQL Server jobs in Powershell....as in...if a job was successfull, the output of lastrunoutcome is "Success" in green....if failed, then "Failed" in red. I have the script working to get the desired job status...I just don't know how to change the colors. Here's what I have so far: # Check for failed SQL jobs on multiple servers [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null foreach ($svr in get-content "C:\serverlist2.txt") { $a = get-date $BegDate = (Get-Date $a.AddDays(-1) -f d) + " 12:00:00 AM" $BegDateTrans = [system.datetime]$BegDate write-host $svr $srv=New-Object "Microsoft.SqlServer.Management.Smo.Server" "$svr" $srv.jobserver.jobs | where-object {$_.lastrundate -ge $BegDateTrans -and $_.Name -notlike "????????-????-????-????-????????????"} | format-table name,lastrunoutcome,lastrundate -autosize foreach ($_.lastrunoutcome in $srv.jobserver.jobs) { if ($_.lastrunoutcome = 0) { -forgroundcolor red } else {} } } This seems to be the closest I've gotten...but it's giving me an error of ""LastRunOutcome" is a ReadOnly property." Any help would be greatly appreciated! Thanks! Emo

• JLayeredPane versus Container layering

  - by Gili

  JLayeredPane allows one to stack multiple Components on top of one another using JLayeredPane.add(Component, Integer). Components in higher "layers" display on top of Components in lower "layers". Container.add(Component, int) provides a similar mechanism whereby Components with lower indexes display on top of Components with higher indexes. Please note that the first mechanism uses Integer and the second mechanism uses int. Also, one renders high values on top of low ones, and the other does the opposite. Do not mix the two :) My question is: what's the point of using JLayeredPane when Container already provides the same mechanism? Does one layer components better than the another? UPDATE: There is also Container.setComponentZOrder(Component, int) to consider.

• Windows XP Home Edition SP3 cant recognise PCMIA SD Card

  - by Pozo

  System Specifications: Laptop : Dell Inspiron 6000 OS: Windows Home Edition SP3 SD Adapter: Hagiwara Smart Media Adapter I inserted the card into the slot, windows xp recognises the device, lists the pcmia controller on the device manager list, an entry appears under the IDE ATA/ATAPI category on the device manager as well. However, the device does not show under my computer and the driver does not get assigned a letter number. I checked the system logs from the device manager and there were no logged errors. Checking the Hagiwara support website, the manufacturer indicates that the adapter driver is the same as the windows xp pcmia controller. Checking Dell's website, no specific drivers were listed for that either. General Search on the web indicates that multiple people face similar problems with their SD cards, yet none actually spell out the route issue that causes this. Please let me know if you have any suggestions for further debugging. Thanks in advance

• XSLT: How to escape square brackets in Urls

  - by ilariac

  I have a set of records from Solr where field[@name='url'] can have the following format: http://url/blabla/blabla.aspx?sv=[keyword%20keyword,%201] My understanding is that the square brackets denote an array syntax and I would like to use XSLT to remove the square brackets from all Urls. The reason for this is that I am using an Open URL resolver, which does not currently handle well those characters. The best option would be to strip the square brackets from all URLs before such resources are mediated by the Open URL resolver. There are cases where I have multiple occurrences of square brackets per Url. Can you please help me with this? Thanks for your help, I.

• How to get `gcc` to generate `bts` instruction for x86-64 from standard C?

  - by Norman Ramsey

  Inspired by a recent question, I'd like to know if anyone knows how to get gcc to generate the x86-64 bts instruction (bit test and set) on the Linux x86-64 platforms, without resorting to inline assembly or to nonstandard compiler intrinsics. Related questions: Why doesn't gcc do this for a simple |= operation were the right-hand side has exactly 1 bit set? How to get bts using compiler intrinsics or the asm directive Portability is more important to me than bts, so I won't use and asm directive, and if there's another solution, I prefer not to use compiler instrinsics. EDIT: The C source language does not support atomic operations, so I'm not particularly interested in getting atomic test-and-set (even though that's the original reason for test-and-set to exist in the first place). If I want something atomic I know I have no chance of doing it with standard C source: it has to be an intrinsic, a library function, or inline assembly. (I have implemented atomic operations in compilers that support multiple threads.)

• VS 2010 breaks my keydown events

  - by Erik Karlsson

  I have a custom control, a groupbox, which reacts on key events on a assigned key. It is possible to remove this groupbox, as well as adding more dynamically. Havnt been any trouble in VS 2008 so far. Two days ago i installed VS 2010. And i started to get multiple event fireing, and removing a groupbox did not remove the specific key events attached to it. Where did it go wrong? I use -= on the events present in the gruopbox code to remove them before removing the groupbox.

• Persisting hashlib state

  - by anthony

  I'd like to create a hashlib instance, update() it, then persist its state in some way. Later, I'd like to recreate the object using this state data, and continue to update() it. Finally, I'd like to get the hexdigest() o the total cumulative run of data. State persistence has to survive across multiple runs. Example: import hashlib m = hashlib.sha1() m.update('one') m.update('two') # somehow, persist the state of m here #later, possibly in another process # recreate m from the persisted state m.update('three') m.update('four') print m.hexdigest() # at this point, m.hexdigest() should be equal to hashlib.sha1().update('onetwothreefour').hextdigets()

• is there a such thing as a randomly accessible pseudo-random number generator? (preferably open-sour

  - by lucid

  first off, is there a such thing as a random access random number generator, where you could not only sequentially generate random numbers as we're all used to, assuming rand100() always generates a value from 0-100: for (int i=0;i<5;i++) print rand100() output: 14 75 36 22 67 but also randomly access any random value like: rand100(0) would output 14 as long as you didn't change the seed rand100(3) would always output 22 rand100(4) would always output 67 and so on... I've actually found an open-source generator algorithm that does this, but you cannot change the seed. I know that pseudorandomness is a complex field; I wouldn't know how to alter it to add that functionality. Is there a seedable random access random number generator, preferably open source? or is there a better term for this I can google for more information? if not, part 2 of my question would be, is there any reliably random open source conventional seedable pseudorandom number generator so I could port it to multiple platforms/languages while retaining a consistent sequence of values for each platform for any given seed?

• System.Drawing.Image for Images in Business Objects?

  - by Mudu

  Hi Folks I'd like to store an image in a business object. In MSDN I saw that the System.Drawing-namespace provides lots of GDI+-features, etc. Is it okay to store an Image in an System.Drawing.Image class in business layer (which is a class library "only"), and thus including a reference to System.Drawing too? I slightly feel just kind of bad doing that, 'cause it seems like I have UI-specific references in business code. Moreover, the code could become unnecessarily platform-dependant (though this is only a problem in theory, because we do not develop for multiple platforms). If it isn't right that way, which type would fit best? Thank you for any response! Matthias

• Synchronising scripts / db / files from dev system to web server

  - by Spoonface

  I work as a freelance web dev, and up until now have been ftping my scripts / databases / static files to my web server manually, but I'm finding that is too error prone. So I'm looking for an app to automate uploading new and updated scripts / files / databases / etc. I know a lot of independent devs use WinSCP or Unison, but I don't think those apps can synch databases. Does anyone have any other suggestions? It doesn't need to be anything overly feature rich as I'm not working within a team or across multiple operating systems or anything like that. I can purchase any reasonably priced license if necesary. My work is primarily for PHP / MySQL / Apache on a Windows system, and then uploaded to a Linux / Apache server. thanks for your time!

• Convert any currency string to double

  - by James

  I need to store multiple currencies in SQL server. I understand that SQL won't support all different types of currencies (unless I store it as a string, but I don't want to do that). My idea was to convert all the values from their currency format to a standard double and store that instead. Then just re-format based on the culture info when displaying. However, I have tried doing something like e.g. var cultureInfo = new System.Globalization.CultureInfo("en-US"); double plain = return Double.Parse("$20,000.00", cultureInfo); This doesn't ever seem to work it always throws a FormatException. Even removing the currency symbol and just trying to do this based on the number alone does the same thing. This is just an example I want to support pretty much any type of currency. Is there a standard way of stripping out currency and getting the value as a double?

• Have problem understanding the id/name of java bean

  - by symfony

  In an XmlBeanFactory (including ApplicationContext variants), you use the id or name attributes to specify the bean id(s), and at least one id must be specified in one or both of these attributes. Does it mean the following are legal? <bean id="test"> <bean name="test"> But this is illegal: <bean non_idnorname="test"> you may also or instead specify one or more bean ids (separated by a comma (,) or semicolon (;) via the name attribute. Does it mean I can specify multiple ids this way: <bean name="id1;id2,id3"> Can someone convince my doubt?

• How doe we name test methods where we are checking for more than one condition?

  - by Sandbox

  I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectations from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

• Jquery selectors by CSS class in IE is really slow--workarounds?

  - by Sam Lee

  I have a web app where I have several elements with class="classA". I want to select and apply a function to all of them. I am doing the obvious thing, which is $(".classA").each(function () { ... }). This works just fine in Chrome/Safari/Firefox but is really slow in IE. It turns out IE has serious performance issues when selecting things by CSS class in jQuery. I was wondering if anyone has suggestions on good ways to deal with this. I can't use ID selectors because there can be multiple DOM elements I want to select.

• Completing install of ruby 1.9.3 with Ruby for for Mac OS X 10.7.5 Leopard, Xcode 4.5.2 -- problems with rvm pkg install openssl

  - by user1848361

  First, many thanks in advance for any help. I'm a complete novice with programming and I'm trying to get started with this Ruby on Rails tutorial (http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2) I have been trying figure this out for about 7 hours now and since I don't have any hair left to pull out I'm turning to these hallowed pages. I have searched for solutions here again and again. System: Mac OS X 10.7.5 Leopard, Xcode 4.5.2 I installed homebrew and have updated it multiple times I used homebrew to install rvm and have updated it multiple times I installed git The standard ruby on the system (checking with $ ruby -v) is 1.8.7 My problem is that every time I try to use rvm to install a new version of Ruby ($ rvm install 1.9.3) I get the following error: Ruby (and needed base gems) for your selection will be installed shortly. Before it happens, please read and execute the instructions below. Please use a separate terminal to execute any additional commands. Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' For Opal: Install Nodejs with NPM. See http://nodejs.org/download/ To use an RVM installed Ruby as default, instead of the system ruby: rvm install 1.8.7 # installs patch 357: closest supported version rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems rvm alias create default 1.8.7 And reopen your terminal windows. Xcode and gcc: : I have performed $ brew install libksba and when I try to do it again it tells me that libksba is installed already. When I type "$ rvm requirements" I get: Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK.

Xcode and gcc: Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2. Xcode 4.1 and earlier: - Ruby will build fine. Xcode 4.2 and later (including Command Line Tools for Xcode): - If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine. - If you don't have gcc-4.2, you have two options to get it: * Install apple-gcc42 from Homebrew * Install osx-gcc-installer Homebrew: If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes: brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Xcode 4.2+ install or/and Command Line Tools for Xcode is required to provide make and other tools. osx-gcc-installer: If you don't use Homebrew, you can download and install osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer. Warning: Installing osx-gcc-installer on top of a recent Xcode is known to cause problems, so you must uninstall Xcode before installing osx-gcc-installer. Afterwards you may install Xcode 4.2+ or Command Line Tools for Xcode if you desire. ** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer. So I assume I have to do something with brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Everything seemed to work fine until "$ rvm pkg install openssl", which returns: Fetching openssl-1.0.1c.tar.gz to /Users/thierinvestmentservices/.rvm/archives Extracting openssl to /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c Configuring openssl in /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c.
