• MSBuild: TlbImp error since upgrading to VS 2010

  - by floele

  Hi, since upgrading my project to VS2010, including the use of MSBuild v4 instead of 3.5 (and not making any other changes), I get the following build error and have no clue how to fix it (log from CC.NET): <target name="ResolveComReferences" success="false"> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\NMSDVDXU.dll /namespace:NMSDVDXLib /machine:X64 /out:obj\x64\Release\Interop.NMSDVDXLib.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "NMSDVDXLib" wurde nicht gefunden.]]></warning> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\StarBurnX12.dll /namespace:RocketDivision.StarBurnX /machine:X64 /out:obj\x64\Release\Interop.RocketDivision.StarBurnX.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "RocketDivision.StarBurnX" wurde nicht gefunden.]]></warning> </target> Problem: A single valid machine type compatible with the input type library must be specified. It only applies to the x64 build of my project, x86 still works fine. Apparently, it tries to build a x64 interop assembly from the x86 DLL located in "C:\Assemblies". When executing the TlbImp command with the x64 DLL which is located in a different directory, it works fine. However, I don't know how I can configure my project to use different COM references for the x86 and x64 build. The OS on which the project is being compiled is WinXP x86. Building worked fine when using VS2005 + MSBuild 3.5 Any help would be highly appreciated. I tried building the upgraded project with MSBuild v3.5, but that doesn't work either. It complains about unknown NoWarn codes (probably new in 4.0).

• MVC2 and MVC Futures causing RedirectToAction issues

  - by Darragh

  I've been trying to get the strongly typed version of RedirectToAction from the MVC Futures project to work, but I've been getting no where. Below are the steps I've followed, and the errors I've encountered. Any help is much appreciated. I created a new MVC2 app and changed the About action on the HomeController to redirect to the Index page. Return RedirectToAction("Index") However, I wanted to use the strongly typed extensions, so I downloaded the MVC Futures from CodePlex and added a reference to Microsoft.Web.Mvc to my project. I addded the following "import" statement to the top of HomeContoller.vb Imports Microsoft.Web.Mvc I commented out the above RedirectToAction and added the following line: Return RedirectToAction(Of HomeController)(Function(c) c.Index()) So far, so good. However, I noticed if I uncomment out the first (non Generic) RedirectToAction, it was now causing the following compile error: Error 1 Overload resolution failed because no accessible 'RedirectToAction' can be called with these arguments: Extension method 'Public Function RedirectToAction(Of TController)(action As System.Linq.Expressions.Expression(Of System.Action(Of TController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Data type(s) of the type parameter(s) cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error. Extension method 'Public Function RedirectToAction(action As System.Linq.Expressions.Expression(Of System.Action(Of HomeController))) As System.Web.Mvc.RedirectToRouteResult' defined in 'Microsoft.Web.Mvc.ControllerExtensions': Value of type 'String' cannot be converted to 'System.Linq.Expressions.Expression(Of System.Action(Of mvc2test1.HomeController))'. Even though intelli-sense was showing 8 overloads (the original 6 non-generic overloads, plus the 2 new generic overloads from the Futures assembly), it seems when trying to complie the code, the compiler would only 'find' the 2 non-gneneric extension methods from the Futures assessmbly. I thought this might be an issue that I was using conflicting versions of the MVC2 assembly, and the futures assembly, so I added MvcDiaganotics.aspx from the Futures download to my project and everytyhing looked correct: ASP.NET MVC Assembly Information (System.Web.Mvc.dll) Assembly version: ASP.NET MVC 2 RTM (2.0.50217.0) Full name: System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 Code base: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Web.Mvc/2.0.0.0__31bf3856ad364e35/System.Web.Mvc.dll Deployment: GAC-deployed ASP.NET MVC Futures Assembly Information (Microsoft.Web.Mvc.dll) Assembly version: ASP.NET MVC 2 RTM Futures (2.0.50217.0) Full name: Microsoft.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null Code base: file:///xxxx/bin/Microsoft.Web.Mvc.DLL Deployment: bin-deployed This is driving me crazy! Becuase I thought this might be some VB issue, I created a new MVC2 project using C# and tried the same as above. I added the following "using" statement to the top of HomeController.cs using Microsoft.Web.Mvc; This time, in the About action method, I could only manage to call the non-generic RedirectToAction by typing the full commmand as follows: return Microsoft.Web.Mvc.ControllerExtensions.RedirectToAction<HomeController>(this, c => c.Index()); Even though I had a "using" statement at the top of the class, if I tried to call the non-generic RedirectToAction as follows: return RedirectToAction<HomeController>(c => c.Index()); I would get the following compile error: Error 1 The non-generic method 'System.Web.Mvc.Controller.RedirectToAction(string)' cannot be used with type arguments What gives? It's not like I'm trying to do anything out of the ordinary. It's a simple vanilla MVC2 project with only a reference to the Futures assembly. I'm hoping that I've missed out something obvious, but I've been scratching my head for too long, so I figured I'd seek some assisstance. If anyone's managed to get this simple scenario working (in VB and/or C#) could they please let me know what, if anything, they did differently? Thanks!

• Using MS Standalone profiler in VS2008 Professional

• How does this decorator make a call to the 'register' method?

  - by BryanWheelock

  I'm trying to understand what is going on in the decorator @not_authenticated. The next step in the TraceRoute is to the method 'register' which is also located in django_authopenid/views.py which I just don't understand because I don't see anywhere that register is even mentioned in signin() How is the method 'register' called? def not_authenticated(func): """ decorator that redirect user to next page if he is already logged.""" def decorated(request, *args, **kwargs): if request.user.is_authenticated(): next = request.GET.get("next", "/") return HttpResponseRedirect(next) return func(request, *args, **kwargs) return decorated @not_authenticated def signin(request,newquestion=False,newanswer=False): """ signin page.

• Calling Grep inside Java gives incorrect results while calling grep in shell gives correct results.

  - by futureelite7

  I've got a problem where calling grep from inside java gives incorrect results, as compared to the results from calling grep on the same file in the shell. My grep command (called both in Java and in bash. I escaped the slash in Java accordingly): /bin/grep -vP --regexp='^[0-9]+\t.*' /usr/local/apache-tomcat-6.0.18/work/Catalina/localhost/saccitic/237482319867147879_1271411421 Java Code: String filepath = "/path/to/file"; String options = "P"; String grepparams = "^[0-9]+\\t.*"; String greppath = "/bin/"; String[] localeArray = new String[] { "LANG=", "LC_COLLATE=C", "LC_CTYPE=UTF-8", "LC_MESSAGES=C", "LC_MONETARY=C", "LC_NUMERIC=C", "LC_TIME=C", "LC_ALL=" }; options = "v"+options; //Assign optional params if (options.contains("P")) { grepparams = "\'"+grepparams+"\'"; //Quote the regex expression if -P flag is used } else { options = "E"+options; //equivalent to calling egrep } proc = sysRuntime.exec(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath, localeArray); System.out.println(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath); inStream = proc.getInputStream(); The command is supposed to match and discard strings like these: 85295371616 Hi Mr Lee, please be informed that...

Am I passing in the locale information incorrectly, or is the problem something else entirely?

• Ubuntu 9.10 and Squid 2.7 Transparent Proxy TCP_DENIED

  - by user298814

  Hi, We've spent the last two days trying to get squid 2.7 to work with ubuntu 9.10. The computer running ubuntu has two network interfaces: eth0 and eth1 with dhcp running on eth1. Both interfaces have static ip's, eth0 is connected to the Internet and eth1 is connected to our LAN. We have followed literally dozens of different tutorials with no success. The tutorial here was the last one we did that actually got us some sort of results: http://www.basicconfig.com/linuxnetwork/setup_ubuntu_squid_proxy_server_beginner_guide. When we try to access a site like seriouswheels.com from the LAN we get the following message on the client machine: ERROR The requested URL could not be retrieved Invalid Request error was encountered while trying to process the request: GET / HTTP/1.1 Host: www.seriouswheels.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.9 (KHTML, like Gecko) Chrome/5.0.307.11 Safari/532.9 Cache-Control: max-age=0 Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,/;q=0.5 Accept-Encoding: gzip,deflate,sdch Cookie: __utmz=88947353.1269218405.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none); __qca=P0-1052556952-1269218405250; __utma=88947353.1027590811.1269218405.1269218405.1269218405.1; __qseg=Q_D Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Some possible problems are: Missing or unknown request method.

Something somewhere is wrong but we cannot figure out where. Our end goal for all of this is the superimpose content onto every page that a client requests on the LAN. We've been told that squid is the way to do this but at this point in the game we are just trying to get squid setup correctly as our proxy.

• Audio Recording with Appcelerator on Android

  - by user951793

  I would like to record audio and then send the file to a webserver. I am using Titanium 1.8.2 on Win7. The application I am woring on is both for Android and iphone and I do realise that Titanium.Media.AudioRecorder and Titanium.Media.AudioPlayer are for these purpose. Let's concentrate on android for a while. On that platform you can achieve audio recording by creating an intent and then you handle the file in your application. See more here. This implementation has a couple of drawbacks: You cannot stay in your application (as a native audio recorder will start up) You only get back an uri from the recorder and not the actual file. Another implementation is done by Codeboxed. This module is for recording an audio without using intents. The only problem that I could not get this working (along with other people) and the codeboxed team does not respond to anyone since last year. So my question is: Do you know how to record audio on android without using an intent? Thanks in advance. Edit: My problem with codeboxed's module: I downloaded the module from here. I copied the zip file into my project directory. I edited my manifest file with: <modules> <module platform="android" version="0.1">com.codeboxed.audiorecorder</module> </modules> When I try and compile I receive the following error: [DEBUG] appending module: com.mwaysolutions.barcode.TitaniumBarcodeModule [DEBUG] module_id = com.codeboxed.audiorecorder [ERROR] The 'apiversion' for 'com.codeboxed.audiorecorder' in the module manifest is not a valid value. Please use a version of the module that has an 'apiversion' value of 2 or greater set in it's manifest file [DEBUG] touching tiapp.xml to force rebuild next time: E:\TitaniumProjects\MyProject\tiapp.xml I can manage to recognise the module by editing the module's manifest file to this: ` version: 0.1 description: My module author: Your Name license: Specify your license copyright: Copyright (c) 2011 by Your Company apiversion: 2 name: audiorecorder moduleid: com.codeboxed.audiorecorder guid: 747dce68-7d2d-426a-a527-7c67f4e9dfad platform: android minsdk: 1.7.0` But Then again I receive error on compiling: [DEBUG] "C:\Program Files\Java\jdk1.6.0_21\bin\javac.exe" -encoding utf8 -classpath "C:\Program Files (x86)\Android\android-sdk\platforms\android-8\android.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-media.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-platform.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\titanium.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\thirdparty.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\jaxen-1.1.1.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-locale.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-app.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-gesture.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-analytics.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\kroll-common.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-network.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\ti-commons-codec-1.3.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-ui.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-database.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\kroll-v8.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-xml.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\android-support-v4.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-filesystem.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\modules\titanium-android.jar;E:\TitaniumProjects\MyProject\modules\android\com.mwaysolutions.barcode\0.3\barcode.jar;E:\TitaniumProjects\MyProject\modules\android\com.mwaysolutions.barcode\0.3\lib\zxing.jar;E:\TitaniumProjects\MyProject\modules\android\com.codeboxed.audiorecorder\0.1\audiorecorder.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\kroll-apt.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\lib\titanium-verify.jar;C:\Users\Gabor\AppData\Roaming\Titanium\mobilesdk\win32\1.8.2\android\lib\titanium-debug.jar" -d E:\TitaniumProjects\MyProject\build\android\bin\classes -proc:none -sourcepath E:\TitaniumProjects\MyProject\build\android\src -sourcepath E:\TitaniumProjects\MyProject\build\android\gen @c:\users\gabor\appdata\local\temp\tmpbqmjuy [ERROR] Error(s) compiling generated Java code [ERROR] E:\TitaniumProjects\MyProject\build\android\gen\com\petosoft\myproject\MyProjectApplication.java:44: cannot find symbol symbol : class AudiorecorderBootstrap location: package com.codeboxed.audiorecorder runtime.addExternalModule("com.codeboxed.audiorecorder", com.codeboxed.audiorecorder.AudiorecorderBootstrap.class); ^ 1 error

• How to pre-load all deployed assemblies for an AppDomain

  - by Andras Zoltan

  Given an App Domain, there are many different locations that Fusion (the .Net assembly loader) will probe for a given assembly. Obviously, we take this functionality for granted and, since the probing appears to be embedded within the .Net runtime (Assembly._nLoad internal method seems to be the entry-point when Reflect-Loading - and I assume that implicit loading is probably covered by the same underlying algorithm), as developers we don't seem to be able to gain access to those search paths. My problem is that I have a component that does a lot of dynamic type resolution, and which needs to be able to ensure that all user-deployed assemblies for a given AppDomain are pre-loaded before it starts its work. Yes, it slows down startup - but the benefits we get from this component totally outweight this. The basic loading algorithm I've already written is as follows. It deep-scans a set of folders for any .dll (.exes are being excluded at the moment), and uses Assembly.LoadFrom to load the dll if it's AssemblyName cannot be found in the set of assemblies already loaded into the AppDomain (this is implemented inefficiently, but it can be optimized later): void PreLoad(IEnumerable<string> paths) { foreach(path p in paths) { PreLoad(p); } } void PreLoad(string p) { //all try/catch blocks are elided for brevity string[] files = null; files = Directory.GetFiles(p, "*.dll", SearchOption.AllDirectories); AssemblyName a = null; foreach (var s in files) { a = AssemblyName.GetAssemblyName(s); if (!AppDomain.CurrentDomain.GetAssemblies().Any( assembly => AssemblyName.ReferenceMatchesDefinition( assembly.GetName(), a))) Assembly.LoadFrom(s); } } LoadFrom is used because I've found that using Load() can lead to duplicate assemblies being loaded by Fusion if, when it probes for it, it doesn't find one loaded from where it expects to find it. So, with this in place, all I now have to do is to get a list in precedence order (highest to lowest) of the search paths that Fusion is going to be using when it searches for an assembly. Then I can simply iterate through them. The GAC is irrelevant for this, and I'm not interested in any environment-driven fixed paths that Fusion might use - only those paths that can be gleaned from the AppDomain which contain assemblies expressly deployed for the app. My first iteration of this simply used AppDomain.BaseDirectory. This works for services, form apps and console apps. It doesn't work for an Asp.Net website, however, since there are at least two main locations - the AppDomain.DynamicDirectory (where Asp.Net places it's dynamically generated page classes and any assemblies that the Aspx page code references), and then the site's Bin folder - which can be discovered from the AppDomain.SetupInformation.PrivateBinPath property. So I now have working code for the most basic types of apps now (Sql Server-hosted AppDomains are another story since the filesystem is virtualised) - but I came across an interesting issue a couple of days ago where this code simply doesn't work: the nUnit test runner. This uses both Shadow Copying (so my algorithm would need to be discovering and loading them from the shadow-copy drop folder, not from the bin folder) and it sets up the PrivateBinPath as being relative to the base directory. And of course there are loads of other hosting scenarios that I probably haven't considered; but which must be valid because otherwise Fusion would choke on loading the assemblies. I want to stop feeling around and introducing hack upon hack to accommodate these new scenarios as they crop up - what I want is, given an AppDomain and its setup information, the ability to produce this list of Folders that I should scan in order to pick up all the DLLs that are going to be loaded; regardless of how the AppDomain is setup. If Fusion can see them as all the same, then so should my code. Of course, I might have to alter the algorithm if .Net changes its internals - that's just a cross I'll have to bear. Equally, I'm happy to consider SQL Server and any other similar environments as edge-cases that remain unsupported for now. Any ideas!?

• AppDomain dependencies across directories

  - by strager

  I am creating a plugin system and I am creating one AppDomain per plugin. Each plugin has its own directory with its main assemblies and references. The main assemblies will be loaded by my plugin loader, in addition to my interface assemblies (so the plugin can interact with the application). Creating the AppDomain: this.appDomain = AppDomain.CreateDomain("AppDomain", null, new AppDomainSetup { ApplicationBase = pluginPath, PrivateBinPath = pluginPath, }); Loading the assemblies: this.appDomain.Load(myInterfaceAssembly.GetName(true)); var assemblies = new List<Assembly>(); foreach (var assemblyName in this.assemblyNames) { assemblies.Add(this.appDomain.Load(assemblyName)); } The format of assemblyName is the assembly's filename without ".dll". The problem is that AppDomain.Load(assemblyName) throws an exception: Could not load file or assembly '[[assemblyName]], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. All of the dependencies of [[assemblyName]] are: Inside the directory pluginPath, The myInterfaceAssembly which is already loaded, or In the GAC (e.g. mscorelib). Clearly I'm not doing something right. I have tried: Creating an object using this.appDomain.CreateInstanceAndUnwrap inheriting from MarshalByRefObject with a LoadAssembly method to load the assembly. I get an exception saying that the current assembly (containing the proxy class) could not be loaded (file not found, as above), even if I manually call this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true)). Attaching an AssemblyResolve handler to this.appDomain. I'm met with the same exception as in (1), and manually loading doesn't help. Recursively loading assemblies by loading their dependencies into this.appDomain first. This doesn't work, but I doubt my code is correct: private static void LoadAssemblyInto(AssemblyName assemblyName, AppDomain appDomain) { var assembly = Assembly.Load(assemblyName); foreach (var referenceName in assembly.GetReferencedAssemblies()) { if (!referenceName.FullName.StartsWith("MyProject")) { continue; } var loadedAssemblies = appDomain.GetAssemblies(); if (loadedAssemblies.Any((asm) => asm.FullName == referenceName.FullName)) { continue; } LoadAssemblyInto(referenceName, appDomain); } appDomain.Load(assembly.GetName(true)); } How can I load my plugin assembly with its dependencies in that plugin's directory while also loading some assemblies in the current directory? Note: The assemblies a plugin may (probably will) reference are already loaded in the current domain. This can be shared across domains (performance benefit? simplicity?) if required. Fusion log: *** Assembly Binder Log Entry (12/24/2010 @ 10:46:40 AM) *** The operation failed. Bind result: hr = 0x80070002. The system cannot find the file specified.

• codes to convert from avi to asf

  - by George2

  Hello everyone, No matter what library/SDK to use, I want to convert from avi to asf very quickly (I could even sacrifice some quality of video and audio). I am working on Windows platform (Vista and 2008 Server), better .Net SDK/code, C++ code is also fine. :-) I learned from the below link, that there could be a very quick way to convert from avi to asf to support streaming better, as mentioned "could convert the video from AVI to ASF format using a simple copy (i.e. the content is the same, but container changes).". My question is after some hours of study and trial various SDK/tools, as a newbie, I do not know how to begin with so I am asking for reference sample code to do this task. :-) (as this is a different issue, we decide to start a new topic. :-) ) http://stackoverflow.com/questions/743220/streaming-avi-file-issue thanks in advance, George EDIT 1: I have tried to get the binary of ffmpeg from, http://ffmpeg.arrozcru.org/autobuilds/ffmpeg-latest-mingw32-static.tar.bz2 then run the following command, C:\software\ffmpeg-latest-mingw32-static\bin>ffmpeg.exe -i test.avi -acodec copy -vcodec copy test.asf FFmpeg version SVN-r18506, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-memalign-hack --prefix=/mingw --cross-prefix=i686-ming w32- --cc=ccache-i686-mingw32-gcc --target-os=mingw32 --arch=i686 --cpu=i686 --e nable-avisynth --enable-gpl --enable-zlib --enable-bzlib --enable-libgsm --enabl e-libfaac --enable-pthreads --enable-libvorbis --enable-libmp3lame --enable-libo penjpeg --enable-libtheora --enable-libspeex --enable-libxvid --enable-libfaad - -enable-libschroedinger --enable-libx264 libavutil 50. 3. 0 / 50. 3. 0 libavcodec 52.25. 0 / 52.25. 0 libavformat 52.32. 0 / 52.32. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0. 7. 1 / 0. 7. 1 built on Apr 14 2009 04:04:47, gcc: 4.2.4 Input #0, avi, from 'test.avi': Duration: 00:00:44.86, start: 0.000000, bitrate: 5291 kb/s Stream #0.0: Video: msvideo1, rgb555le, 1280x1024, 5 tbr, 5 tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Output #0, asf, to 'test.asf': Stream #0.0: Video: CRAM / 0x4D415243, rgb555le, 1280x1024, q=2-31, 1k tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 224 fps=222 q=-1.0 Lsize= 29426kB time=44.80 bitrate=5380.7kbits/s video:26910kB audio:1932kB global headers:0kB muxing overhead 2.023317% C:\software\ffmpeg-latest-mingw32-static\bin> http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6 then have the following error when using Windows Media Player to play it, does anyone have any ideas? http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6

• Flushing a queue using AMQP, Rabbit, and Ruby

  - by jeffshantz

  I'm developing a system in Ruby that is going to make use of RabbitMQ to send messages to a queue as it does some work. I am using: Ruby 1.9.1 Stable RabbitMQ 1.7.2 AMQP gem v0.6.7 (http://github.com/tmm1/amqp) Most of the examples I have seen on this gem have their publish calls in an EM.add_periodic_timer block. This doesn't work for what I suspect is a vast majority of use cases, and certainly not for mine. I need to publish a message as I complete some work, so putting a publish statement in an add_periodic_timer block doesn't suffice. So, I'm trying to figure out how to publish a few messages to a queue, and then "flush" it, so that any messages I've published are then delivered to my subscribers. To give you an idea of what I mean, consider the following publisher code: #!/usr/bin/ruby require 'rubygems' require 'mq' MESSAGES = ["hello","goodbye","test"] AMQP.start do queue = MQ.queue('testq') messages_published = 0 while (messages_published < 50) if (rand() < 0.4) message = MESSAGES[rand(MESSAGES.size)] puts "#{Time.now.to_s}: Publishing: #{message}" queue.publish(message) messages_published += 1 end sleep(0.1) end AMQP.stop do EM.stop end end So, this code simply loops, publishing a message with 40% probability on each iteration of the loop, and then sleeps for 0.1 seconds. It does this until 50 messages have been published, and then stops AMQP. Of course, this is just a proof of concept. Now, my subscriber code: #!/usr/bin/ruby require 'rubygems' require 'mq' AMQP.start do queue = MQ.queue('testq') queue.subscribe do |header, msg| puts "#{Time.now.to_s}: Received #{msg}" end end So, we just subscribe to the queue, and for each message received, we print it out. Great, except that the subscriber only receives all 50 messages when the publisher calls AMQP.stop. Here's the output from my publisher. It has been truncated in the middle for brevity: $ ruby publisher.rb 2010-04-14 21:45:42 -0400: Publishing: test 2010-04-14 21:45:42 -0400: Publishing: hello 2010-04-14 21:45:42 -0400: Publishing: test 2010-04-14 21:45:43 -0400: Publishing: test 2010-04-14 21:45:44 -0400: Publishing: test 2010-04-14 21:45:44 -0400: Publishing: goodbye 2010-04-14 21:45:45 -0400: Publishing: goodbye 2010-04-14 21:45:45 -0400: Publishing: test 2010-04-14 21:45:45 -0400: Publishing: test . . . 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: test 2010-04-14 21:45:55 -0400: Publishing: goodbye Next, the output from my subscriber: $ ruby consumer.rb 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received hello 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received goodbye 2010-04-14 21:45:56 -0400: Received goodbye 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test . . . 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received test 2010-04-14 21:45:56 -0400: Received goodbye If you note the timestamps in the output, the subscriber only receives all of the messages once the publisher has stopped AMQP and exited. So, being an AMQP newb, how can I get my messages to deliver immediately? I tried putting AMQP.start and AMQP.stop in the body of the while loop of the publisher, but then only the first message gets delivered -- though strangely, if I turn on logging, there are no error messages reported by the server and the messages do get sent to the queue, but never get received by the subscriber. Suggestions would be much appreciated. Thanks for reading.

• Python bindings for a vala library

  - by celil

  I am trying to create python bindings to a vala library using the following IBM tutorial as a reference. My initial directory has the following two files: test.vala using GLib; namespace Test { public class Test : Object { public int sum(int x, int y) { return x + y; } } } test.override %% headers #include <Python.h> #include "pygobject.h" #include "test.h" %% modulename test %% import gobject.GObject as PyGObject_Type %% ignore-glob *_get_type %% and try to build the python module source test_wrap.c using the following code build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c However, the last command fails with an error $ ./build.sh Traceback (most recent call last): File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1720, in <module> sys.exit(main(sys.argv)) File "/usr/share/pygobject/2.0/codegen/codegen.py", line 1672, in main o = override.Overrides(arg) File "/usr/share/pygobject/2.0/codegen/override.py", line 52, in __init__ self.handle_file(filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 84, in handle_file self.__parse_override(buf, startline, filename) File "/usr/share/pygobject/2.0/codegen/override.py", line 96, in __parse_override command = words[0] IndexError: list index out of range Is this a bug in pygobject, or is something wrong with my setup? What is the best way to call code written in vala from python? EDIT: Removing the extra line fixed the current problem, but now as I proceed to build the python module, I am facing another problem. Adding the following C file to the existing two in the directory: test_module.c #include <Python.h> void test_register_classes (PyObject *d); extern PyMethodDef test_functions[]; DL_EXPORT(void) inittest(void) { PyObject *m, *d; init_pygobject(); m = Py_InitModule("test", test_functions); d = PyModule_GetDict(m); test_register_classes(d); if (PyErr_Occurred ()) { Py_FatalError ("can't initialise module test"); } } and building with the following script build.sh #/usr/bin/env bash valac test.vala -CH test.h python /usr/share/pygobject/2.0/codegen/h2def.py test.h > test.defs pygobject-codegen-2.0 -o test.override -p test test.defs > test_wrap.c CFLAGS="`pkg-config --cflags pygobject-2.0` -I/usr/include/python2.6/ -I."

• powermock : ProcessBuilder redirectErrorStream giving nullPointerException

  - by kaustubh9

  I am using powermock to mock some native command invocation using process builder. the strange thing is these test pass sometimes and fail sometimes giving a NPE. Is this a powermock issue or some gotcha in the program. the snippet of the class under test is.. public void method1(String jsonString, String filename) { try { JSONObject jObj = new JSONObject(jsonString); JSONArray jArr = jObj.getJSONArray("something"); String cmd = "/home/y/bin/perl <perlscript>.pl<someConstant>" + " -k " + <someConstant> + " -t " + <someConstant>; cmd += vmArr.getJSONObject(i).getString("jsonKey"); ProcessBuilder pb = new ProcessBuilder("bash", "-c", cmd); pb.redirectErrorStream(false); Process shell = pb.start(); shell.waitFor(); if (shell.exitValue() != 0) { throw new RuntimeException("Error in Collecting the logs. cmd="+cmd); } StringBuilder error = new StringBuilder(); InputStream iError = shell.getErrorStream(); BufferedReader bfr = new BufferedReader( new InputStreamReader(iError)); String line = null; while ((line = bfr.readLine()) != null) { error.append(line + "\n"); } if (!error.toString().isEmpty()) { LOGGER.error(error`enter code here`); } iError.close(); bfr.close(); } catch (Exception e) { throw new RuntimeException(e); } and the unit test case is .. @PrepareForTest( {.class, ProcessBuilder.class,Process.class, InputStream.class,InputStreamReader.class, BufferedReader.class} ) @Test(sequential=true) public class TestClass { @Test(groups = {"unit"}) public void testMethod() { try { ProcessBuilder prBuilderMock = createMock(ProcessBuilder.class); Process processMock = createMock(Process.class); InputStream iStreamMock = createMock(InputStream.class); InputStreamReader iStrRdrMock = createMock(InputStreamReader.class); BufferedReader bRdrMock = createMock(BufferedReader.class); String errorStr =" Error occured"; String json = <jsonStringInput>; String cmd = "/home/y/bin/perl <perlscript>.pl -k "+<someConstant>+" -t "+<someConstant>+" "+<jsonValue>; expectNew(ProcessBuilder.class, "bash", "-c", cmd).andReturn(prBuilderMock); expect(prBuilderMock.redirectErrorStream(false)).andReturn(prBuilderMock); expect(prBuilderMock.start()).andReturn(processMock); expect(processMock.waitFor()).andReturn(0); expect(processMock.exitValue()).andReturn(0); expect(processMock.getErrorStream()).andReturn(iStreamMock); expectNew(InputStreamReader.class, iStreamMock) .andReturn(iStrRdrMock); expectNew(BufferedReader.class, iStrRdrMock) .andReturn(bRdrMock); expect(bRdrMock.readLine()).andReturn(errorStr); expect(bRdrMock.readLine()).andReturn(null); iStreamMock.close(); bRdrMock.close(); expectLastCall().once(); replayAll(); <ClassToBeTested> instance = new <ClassToBeTested>(); instance.method1(json, fileName); verifyAll(); } catch (Exception e) { Assert.fail("failed while collecting log.", e); } } I get an error on execution an the test case fails..

• Java Refuses to Start - Could not reserve enough space for object heap

  - by Randyaa

  Background We have a pool of aproximately 20 linux blades. Some are running Suse, some are running Redhat. ALL share NAS space which contains the following 3 folders: /NAS/app/java - a symlink that points to an installation of a Java JDK. Currently version 1.5.0_10 /NAS/app/lib - a symlink that points to a version of our application. /NAS/data - directory where our output is written All our machines have 2 processors (hyperthreaded) with 4gb of physical memory and 4gb of swap space. We limit the number of 'jobs' each machine can process at a given time to 6 (this number likely needs to change, but that does not enter into the current problem so please ignore it for the time being). Some of our jobs set a Max Heap size of 512mb, some others reserve a Max Heap size of 2048mb. Again, we realize we could go over our available memory if 6 jobs started on the same machine with the heap size set to 2048, but to our knowledge this has not yet occurred. The Problem Once and a while a Job will fail immediately with the following message: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. We used to chalk this up to too many jobs running at the same time on the same machine. The problem happened infrequently enough (MAYBE once a month) that we'd just restart it and everything would be fine. The problem has recently gotten much worse. All of our jobs which request a max heap size of 2048m fail immediately almost every time and need to get restarted several times before completing. We've gone out to individual machines and tried executing them manually with the same result. Debugging It turns out that the problem only exists for our SuSE boxes. The reason it has been happening more frequently is becuase we've been adding more machines, and the new ones are SuSE. 'cat /proc/version' on the SuSE boxes give us: Linux version 2.6.5-7.244-bigsmp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005 'cat /proc/version' on the RedHat boxes give us: Linux version 2.4.21-32.0.1.ELsmp ([email protected]) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)) #1 SMP Tue May 17 17:52:23 EDT 2005 'uname -a' gives us the following on BOTH types of machines: UTC 2005 i686 i686 i386 GNU/Linux No jobs are running on the machine, and no other processes are utilizing much memory. All of the processes currently running might be using 100mb total. 'top' currently shows the following: Mem: 4146528k total, 3536360k used, 610168k free, 132136k buffers Swap: 4194288k total, 0k used, 4194288k free, 3283908k cached 'vmstat' currently shows the following: procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 610292 132136 3283908 0 0 0 2 26 15 0 0 100 0 If we kick off a job with the following command line (Max Heap of 1850mb) it starts fine: java/bin/java -Xmx1850M -cp helloworld.jar HelloWorld Hello World If we bump up the max heap size to 1875mb it fails: java/bin/java -Xmx1875M -cp helloworld.jar HelloWorld Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. It's quite clear that the memory currently being used is for Buffering/Caching and that's why so little is being displayed as 'free'. What isn't clear is why there is a magical 1850mb line where anything higher means Java can't start. Any explanations would be greatly appreciated.

• How do I create something like a negated character class with a string instead of characters?

  - by Chas. Owens

  I am trying to write a tokenizer for Mustache in Perl. I can easily handle most of the tokens like this: #!/usr/bin/perl use strict; use warnings; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { my ($type) = keys %+; (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. But I am running into trouble with the Set Delimiters directive: #!/usr/bin/perl use strict; use warnings; my $delimiters = qr/ \G \{\{ (?<start> .+? ) = [ ] = (?<end> .+?) }} /xs; my $comment = qr/ \G \{\{ ! (?<comment> .+? ) }} /xs; my $variable = qr/ \G \{\{ (?<variable> .+? ) }} /xs; my $text = qr/ \G (?<text> .+? ) (?= \{\{ | \z ) /xs; my $tokens = qr/ $comment | $delimiters | $variable | $text /x; my $s = do { local $/; <DATA> }; while ($s =~ /$tokens/g) { for my $type (keys %+) { (my $contents = $+{$type}) =~ s/\n/\\n/; print "type [$type] contents [$contents]\n"; } } __DATA__ {{!this is a comment}} Hi {{name}}, I like {{thing}}. {{(= =)}} If I change it to my $delimiters = qr/ \G \{\{ (?<start> [^{]+? ) = [ ] = (?<end> .+?) }} /xs; It works fine, but the point of the Set Delimiters directive is to change the delimiters, so the code will wind up looking like my $variable = qr/ \G $start (?<variable> .+? ) $end /xs; And it is perfectly valid to say {{{== ==}}} (i.e. change the delimiters to {= and =}). What I want, but maybe not what I need, is the ability to say something like (?:not starting string)+?. I figure I am just going to have to give up being clean about it and drop code into the regex to force it to match only what I want. I am trying to avoid that for four reasons: I don't think it is very clean. It is marked as experimental. I am not very familier with it (I think it comes down to (?{CODE}) and returning special values. I am hoping someone knows some other exotic feature that I am not familiar with that fits the situation better (e.g. (?(condition)yes-pattern|no-pattern)). Just to make things clear (I hope), I am trying to match a constant length starting delimiter followed by the shortest string that allows a match and does not contain the starting delimiter followed by a space followed by an equals sign followed by the shortest string that allows a match that ends with the ending delimiter.

I've seen quite a few of these problems here on stackoverflow but all seem a bit different or have really complicated solutions. Is there something I'm missing? Something simple? Something stupid? I can provide additional info from the out file if necessary. I've read that some people use SQLite for dev and test then MySQL in prod but that sounds like a pretty horrible idea.

• multple inner joins 3 or more crashes mysql server 5.1.30 opensolaris

  - by user331849

  when doing simple query on 4 inner joined tables, the server crashes with the output below appearing in the the mysql .err file. eg. select * from table1 inner join table2 on table1.a = table2.a and table1.b = table2.b inner join table3 on table2.a = table3.a and table2.c = table3.c inner join table4 on table3.a = table4.a and table3.d = table4.d If i remove one of the tables it executes fine. Likewise if I remove a different table, it executes fine. Though all tables have been checked anyway, this would suggest that it is not a problem specifically with one of the tables. mysql.err trace: 100503 18:13:19 - mysqld got signal 11 ; This could be because you hit a bug.

• Rails destroy confirm with Jquery AJAX

  - by Mike

  I have got this working for the most part. My rails link is: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => 'delete', :confirm => 'Are you sure?', :id => 'trash') %> :class = "delete" is calling an ajax function so that it is deleted and the page isn't refreshed that works great. But because the page doesn't refresh, it is still there. So my id trash is calling this jquery function: $('[id^=trash]').click(function(){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; }); Which is hiding the row of whatever trash icon i clicked on. This also works great. I thought I had it all worked out and then I hit this problem. When you click on my trash can I have this confirm box pop up to ask you if you are sure. Regardless of whether you choose cancel or accept, the jquery fires and it hides the row. It isn't deleted, only hidden till you refresh the page. I tried changing it so that the prompt is done through jquery, but then rails was deleteing the row regardless of what i choose in my prompt because the .destroy function was being called when the prompt was being called. My question really is how can i get the value to cancel or accept from the rails confirm pop up so that in my jquery I can have an if statement that hides if they click accept and does nothing if they click cancel. EDIT: Answering Question below. That did not work. I tried changing my link to: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => "delete", :onclick => "trash") %> and putting this in my jquery function trash(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; } else { //they clicked no. } } But the function was never called. It just deletes it with no prompt and doesn't hide it. But that gave me an idea. I took the delete function that ajax was calling $('a.delete').click (function(){ $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); }); And modified it implementing your code: remove :confirm = 'Are you sure?' $('a.delete').click (function(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); return false; } else { //they clicked no. return false; } }); Which does the trick.
