  • Expression Tree Binary Expression for an 'In' operation

    - by Adam Driscoll
    I'm trying to build an expression tree (still) but getting further! I need to create a BinaryExpression to perform an 'In' comparison between a Member and a collection of items. Hence, the expression should return true if the member is contained within the items. This obviously does not exist: Expression.MakeBinary(ExpressionType.In, memberExpression, constantExpression); constantExpression is a ConstantExpression of type IEnumerable while memberExpression is a MemberExpression of type T. How would I create such an expression?

  • Using Zope object unique id ( _p_oid ) to access object itself

    - by Alex M
    Every Zope object has it's own unique id ( _p_oid ). To convert it into integer value: from Shared.DC.xml.ppml import u64 as decodeObjectId oid = decodeObjectId(getattr(<Object instance>, '_p_oid')) Is it possible to get object itself having it's _p_oid? I tried this: from ZODB.utils import p64 object = <RootObject instance>._p_jar[p64(oid)] But it seems it's a wrong way

  • Sequence reduction in R

    - by drknexus
    Assume you have a vector like so: v <- c(1,1,1,2,2,2,2,1,1,3,3,3,3) How can it be best reduced to a data.frame like this? v.df <- data.frame(value=c(1,2,1,3),repetitions=c(3,4,2,4)) In a procedural language I might just iterate through a loop and build the data.frame as I go, but with a large dataset in R such an approach is inefficient. Any advice?

  • Why is ELMAH creating 2 reports for each error?

    - by Chris F
    I have setup ELMAH to create an XML log as well as send an email every time it encounters and unhandled exception in my ASP.NET MVC web application. However, creates 2 xml files for every error and sends to emails, seemingly identical each time. How do I stop this? My relevant web.config configuration sections are below. I thought the duplicate registration system.web and system.webServer may be causing the issue, but that's not the case. <configSections> ... <sectionGroup name="elmah"> <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" /> <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" /> <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" /> <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" /> </sectionGroup> </configSections> <elmah> <security allowRemoteAccess="no"></security> <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/Logs" /> <errorMail from="[email protected]" to="[email protected]" cc="[email protected]" subject="ELMAH: Site Error" async="true" smtpPort="25" smtpServer="xx.xx.xx.xx" /> </elmah> <system.web> ... <httpHandlers> ... <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> </httpHandlers> <httpModules> ... <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/> </httpModules> </system.web> <!-- for IIS7 --> <system.webServer> ... <modules runAllManagedModulesForAllRequests="true"> ... <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/> </modules> <handlers> ... <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> </handlers> </system.webServer>

  • Difference between Java SE/EE/ME?

    - by Richard Knop
    Which one should I install when I want to start learning Java? I going to start with some basics so I will create simple programs that create files, directories, edit XML files and so on, nothing too complex for now. I guess Java SE (Standard Edition) is the one I should install on my Windows 7 desktop? I already have Komodo IDE which I will use to write Java code.

  • Dynamically create hierachical tableview from file structure

    - by Rob M
    Hi, I have a directory structure of directories and files that I want to render as a tableview in an iphone app. I'd rather have this generated dynamically rather than have to maintain a XML PLIST or whatever. i.e. replicate the Explorer functionality in windows where a user can traverse the structure and then select bundled image files for viewing. Is there any way to do this? Any advice would be appreicated.

However, if I select "iPhone Simulator 3.x", everything is fine.

  • Can rpmbuild ingore files in buildroot?

    - by Noah Campbell
    I have a target directory that is checked into svn. I use the target as the --buildroot when I run rpmbuild. This causes rpmbuild to loose it mind because of the .svn directories in each directory. Is there a way to tell rpmbuild to relax? I looked at svn export target target-build, but it only knows about files tracked by rpm. Perhaps not a bad way to do it, but I'm not quite sure that is the best way.

  • Hibernate: Criteria vs. HQL

    - by cretzel
    What are the pros and cons of using Criteria or HQL? The Criteria API is a nice object-oriented way to express queries in Hibernate, but sometimes Criteria Queries are more difficult to understand/build than HQL. When do you use Criteria and when HQL? What do you prefer in which use cases? Or is it just a matter of taste?

  • ItemsPanel vs Grid vs GridSplitter

    - by bitbonk
    I am currently trying to build a ControlTemplate for an ItemsControl that uses the Grid as its ItemsPanel where each item is stacked horizontally and delimited with a GridSplitter. The basic goal is to have a dynamic bindable ItemsControl where all items stack up in a row and where each item can be resized with a splitter. There are two things I can't wrap my head around: How is the GridSplitter supposed to end up automatically between each item? How do I set Grid.Column for each item.
