  • UIView's frame, bounds, center, origin, when to use what?

    - by Boon
    UIView has the concept of frame, bounds, center, and origin, and they all seem to be interrelated. Most of the time, I deal with frame when setting the position and size of a UIView (or subclass). I understand that the frame is using global coordinate system and the bounds is using coordinate of the local view (therefore it's x and y are 0, but not always), but it's still confusing to me when to use what. Question: Under what context (and what's the right time) the other properties (bounds, center, origin) should be used?

    - by Vaccano
    I created a Coded UI Test from a Microsoft Test Manager recording. The exe it runs is the one the tester recorded against. I want this to be a test I run with my build. How do I change the exe that the coded UI test uses to be the output of: The TFS Build when a TFS Build is being run The local build when the test is being run on my machine.

  • How to use c++0x thread in Android NDK?

  • Using 32 bit g++ to build 64bit binaries on AIX

    - by Thumbeti
    I am trying to build a 64 bit binary from C++ code using 32bit g++ compiler.

  • scalacheck/scalatest not found: how to add it in sbt/scala?

    - by Pavel Reich
    I've installed typesafe-stack from http://typesafe.com/stack/download on my ubuntu12, than I created a play project (g8 typesafehub/play-scala) and now I want to add scalatest or scalacheck to my project. So my_app/project/plugins.sbt has the following lines: // The Typesafe repository resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/" // Use the Play sbt plugin for Play projects addSbtPlugin("play" % "sbt-plugin" % "2.0.1") Then I added scalatest using addSbtPlugin: addSbtPlugin("org.scalatest" %% "scalatest" % "2.0.M1" % "test") and now it fails with the following message when I run 'sbt test' [info] Resolving org.scalatest#scalatest;2.0.M1 ... [warn] module not found: org.scalatest#scalatest;2.0.M1 [warn] ==== typesafe-ivy-releases: tried [warn] http://repo.typesafe.com/typesafe/ivy-releases/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== local: tried [warn] ~/.ivy2/local/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== Typesafe repository: tried [warn] http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom [warn] ==== typesafe-ivy-releases: tried [warn] http://repo.typesafe.com/typesafe/ivy- releases/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== public: tried [warn] http://repo1.maven.org/maven2/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom What I don't understand: why does it use this http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom URL instead of the real one http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1/2.0.M1/scalatest_2.9.1-2.0.M1.pom? Quite the same problem I have with scalacheck: it also tries to download using sbt-version specific artifactId whereas the repository has only scala-version specific. What am I doing wrong? I understand there must be a switch in sbt somewhere, not to use sbt-version as part of the artifact URL? I also tried using this in my plugins.sbt libraryDependencies += "org.scalatest" %% "scalatest" % "2.0.M1" % "test" but looks like it is completely ignored by sbt and scalatest.jar hasn't appeared in the classpath: my_app/test/AppTest.scala:1: object scalatest is not a member of package org [error] import org.scalatest.FunSuite because the output of sbt clean && sbt test has lots of Resolving org.easytesting#fest-util;1.1.6 or just another library, but nothing about scalatest. I use scala 2.9.1 and sbt 0.11.3, trying to use scalatest 2.0.M1 and 1.8; scalacheck: resolvers ++= Seq( "snapshots" at "http://oss.sonatype.org/content/repositories/snapshots", "releases" at "http://oss.sonatype.org/content/repositories/releases" ) libraryDependencies ++= Seq( "org.scalacheck" %% "scalacheck" % "1.9" % "test" ) With the same outcome, i.e. it uses the sbtVersion specific POM URL, which doesn't exist. What am I doing wrong? Thanks.

  • Software tools to automatically decrypt a file, whose encryption algorithm (and/or encryption keys)

    - by Andrew
    I have an idea for encryption that I could program fairly easily to encrypt some local text file. Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike? Or do all those tools rely on advanced knowledge of the encryption process (or intercepted 'keys'), meaning I'd have to build my own cracker for testing?

  • What is the safe way to use fork with Apache::DBI under mod_perl2?

    - by codeholic
    I have a problem when I use Apache::DBI in child processes. The problem is that Apache::DBI provides a single handle for all processes which use it, so I get DBD::mysql::db selectall_arrayref failed: Commands out of sync; you can't run this command now at /usr/local/www/apache22/data/test-fork.cgi line 20. Reconnection doesn't help, since Apache::DBI reconnects in all processes, as I understood the following error The server encountered an internal error and was unable to complete your request. Error message: DBD driver has not implemented the AutoCommit attribute at /usr/local/lib/perl5/site_perl/5.8.9/Apache/DBI.pm line 283. , Here's the origin code: use Data::Dumper 'Dumper'; use DBI (); my $dbh = DBI->connect($dsn, $username, $password, { RaiseError => 1, PrintError => 0, }); my $file = "/tmp/test-fork.tmp"; my $pid = fork; defined $pid or die "fork: $!"; if ($pid) { my $rows = eval { $dbh->selectall_arrayref('SELECT SLEEP(1)') }; print "Content-Type: text/plain\n\n"; print $rows ?

"child: " . Dumper($rows) : $@; close FH; } Is there a safe way to use Apache::DBI with forking? Is there a way to make it create a new connection perhaps?

  • WCF using Spring.NET woes

    - by demius
    Hi everyone, I've torn out all but two hairs on my head trying to get my WCF services hosted in IIS 7.5. I'm using Spring.NET to create my service instances, but I'm having no luck getting it up and running. I encounter the following exception: Could not find a base address that matches scheme http for the endpoint with binding MetadataExchangeHttpBinding. Registered base address schemes are []. My WCF configuration is as follows: <system.serviceModel> <bindings> <wsHttpBinding> <binding name="secureBinding" allowCookies="false"> <security mode="Transport"> <transport clientCredentialType="None"> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <services> <service name="TestService"> <host> <baseAddresses> <add baseAddress="https://ws.local.com/TestService.svc"/> </baseAddresses> </host> <endpoint name="secureEndpoint" contract="Services.Interfaces.ITestService" binding="wsHttpBinding" bindingConfiguration="secureBinding" address="https://ws.local.com/TestService.svc" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> What am I missing here?

  • How do you fix an SVN 409 Conflict Error

    - by NerdStarGamer
    I used to use SVN 1.4 on OS X Leopard and everything was fine. A couple of weeks ago I installed a fresh copy of OS X 10.6. The version of SVN that comes with Snow Leopard is 1.6.5. I went ahead and built my own copy with 1.6.6. I'm using the built in apache server and just hosting repositories locally. Everything appeared to work fine until I actually tried to commit something. Everytime I try to commit a change, I get the following message: Transmitting file data .svn: Commit failed (details follow): svn: MERGE of '/svn/svn2': 409 Conflict (http://localhost) This happens with my old repositories, so I created a couple of new ones. Same deal. I also tried using the 1.6.5 version that comes with the system...same. Finally, I tried upgrading to the latest stable SVN (1.6.9) and still got the same problem. The Apache error logs the following for each failed commit: [Mon Mar 29 19:53:10 2010] [error] [client ::1] Could not MERGE resource "/svn/svn2/!svn/act/d399326f-c20f-424f-bb68-3bb40503b5b1" into "/svn/svn2".

I've tried to Google every variation I can think of for this problem, but the search results are pretty much useless. I'm not using TortoiseSVN or anything special and commits fail on a new repository, so I know it's not a problem with my old repos. Any help would be greatly appreciated.

  • How to make an IDisposable object a class variable?

    I am working with Active Directory using C#. Instantiating the PrincipalContext object seems to be expensive, so I'd like to store one in a class variable. When using PrincipalContext as a local variable, I can use the convenient using syntax. When storing an IDisposable object in a static variable, how do I ensure the object is properly disposed of?

So what better place to ask than here. Where can i find information/documentation on how to install/use/extend the SO q&a system? I want to create a clone for a local community from my city.
