• libvirt and VirtualBox / Getting Started

  - by Marc Lucas

  I'm trying to get started on libvirt with VirtualBox as a virtualization solution. I installed everything and VirtualBox itself is running when using their VBoxHeadless command. However, libvirt fails to connect to VirtualBox: # virsh -c vbox:///session libvir: error : could not connect to vbox:///session error: failed to connect to the hypervisor I could not find any hints in the libvirt documentation that point to whether I have to make any domain specific configuration before using virsh. Does anyone have a hint? Or even better, maybe a tutorial that works through the way of using libvirt, virsh or it's APIs (my later goal) from the ground up.

• Edite, select value from UITableView on the iPhone

  - by Anthony D

  I have a UITableView with a list of names, representing server configurations. I want the user to be able to select a server configuration, add a server config, edit a server config, or just cancel out of the view and return to the main view. I'm having a hard time trying to figure out how to achieve all of that functionality in this view. To select, the user should be able to just tap the server config name and a check will appear next to the name then the user is taken back to the main view automatically (or use a save button instead?). To edit the server config, I would also like the user to be able to tap the server config name and be taken to a detail screen where changes can be made. How can I accomplish both since I want both to be done by tapping the server name (row)? Right now the cancel button seems out of place since the screen is accessed via a UINavigationController. Any suggestions?

• Accessing TFS from Powershell

  - by w4ymo

  Hello I am new to PowerShell and I am trying to get branches from TFS and merge them using a PowerShell script. Unfortunately I am failing a first hurdle. I do have Visual Studio 2010 install on my local machine and can access the TFS server (also 2010) fine. I am running the script from my local machine and have the following lines: $tfs = get-tfs http://TFSServerName:8080/TFSProject $branchfolders = $tfs.VCS.GetItems('$/Dev/Branches/', $tfs.RecursionType::OneLevel) and I receive the following error on the second line 2 above Exception calling "GetItems" with "2" argument(s): "Unable to connect to the remote server" I have configured the TFS server to accept incoming connections on port 8080 which works but I am now not to sure how to resolve this error. Is further configuration required? Thanks for any help given.

• XCode and SVN Error: 200019

  - by Boiler Bill

  So, I haven't been in an XCode project on this machine since last summer, and now when I try to access the repo through SCM Configuration in preferences I get the following error: Error: 200019 (Incompatible library version) Description: Mismatched RA version for 'http': found 1.6.2, expected 1.6.5 I know at some point I updated my subversion client through MacPorts and is probably the cause of the problem. So I located all the svn programs on my path and replaced them with symlinks to the /opt/local/bin/svn client thinking that would do it (note that /usr/bin/svn --version yielded the same error message as XCode. Somehow XCode (3.2.1) is still pointing to some older 1.6.2 files. Can someone point me in the right direction on getting XCode svn integration cleaned up?

• Rails ActionMailer problems on Mac

  - by seth

  I've been working on learning to use Rails the last couple days and I've run into something that I haven't been able to solve with Google. So I'm just creating a basic contact form that sends an email. Everything seems to be working ok in testing, which tells me that the form is working, and ActionMailer was implemented correctly, however, I'm having trouble configuring ActionMailer. I'm running OSX 10.6.2. I have postfix running and have verified that it's running using telnet localhost 25. When I try to use the form I get a "Connection refused" error. This is my current configuration: config.action_mailer.smtp_settings = { :address => 'localhost', :port => 25 } I thought I might need to set :domain but I'm kind of confused on what that should be set to in this situation.

• _CopyWebApplication with web.config transformations

  - by Jeremy

  I am trying to have my web application automatically Publish when a Release build is performed. I'm doing this using the _CopyWebApplication target. I added the following to my .csproj file: <!-- Automatically Publish in Release build. --> <Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> <Target Name="AfterBuild"> <RemoveDir Directories="$(ProjectDir)..\Output\MyWeb" ContinueOnError="true" /> <MSBuild Projects="MyWeb.csproj" Properties="Configuration=Release;WebProjectOutputDir=$(ProjectDir)..\Output\MyWeb;OutDir=$(ProjectDir)bin\" Targets="ResolveReferences;_CopyWebApplication" /> </Target> This works but with one issue. The difference between this output, and the output generated when using the Publish menu item in Visual Studio, is that the Web.Release.config transformation is not applied to the Web.config file when using the MSBuild method. Instead, Web.config, Web.Release.config, and Web.Debug.config are all copied. Any ideas are appreciated.

• java.lang.NoSuchMethodError: main when starting HelloWorld with Eclipse Scala plugin

  - by Matt Sheppard

  I've just been playing with Scala, and installed the Eclipse plugin as described at http://www.scala-lang.org/node/94, but after entering the "Hello World" test example and setting up the run configuration as described, I get the following error Exception in thread "main" java.lang.NoSuchMethodError: main For reference the code is package hello object HelloWorld extends Application { println("Hello World!") } I've tinkered a bit with the obvious solutions (adding a main method, adding a singleton object with a main method) but I'm clearly doing something wrong. Can anyone get their test example to work, or point out what I am doing wrong?

• Copy task in Visual Studio 2008

  - by Maurizio Reginelli

  This is a question related to a previous question I posted (see here). I need to configure a .csproj file to copy some files from a directory to another one (let me call them SOURCE and DESTINATION). I also need to change the SOURCE path depending from the configuration I'm using. For example, if I compile my project in Debug mode, the SOURCE path must contain a subfolder called Debug. I tried the solution proposed by Schmitt in the previous post, using $(ConfigurationName) to set the dynamic directory into the SOURCE path. When I opened the solution containing that project, a list of links to the source files appeared in the main tree of the project and they were correctly related to the Debug mode. But when I changed to the Release mode, I saw that the path of the linked source files were set again to the Debug version. Is there a way to specify a parameter in the Include attribute of the SourceFiles element? Thank you.

• Linq to SQL and SQL Server Compact Error: "There was an error parsing the query."

  - by Jeremy

  I created a SQL server compact database (MyDatabase.sdf), and populated it with some data. I then ran SQLMetal.exe and generated a linq to sql class (MyDatabase.mdf) Now I'm trying to select all records from a table with a relatively straightforward select, and I get the error: "There was an error parsing the query. [ Token line number = 3,Token line offset = 67,Token in error = MAX]" Here is my select code: public IEnumerable ListItems() { MyDatabase db_m = new MyDatabase("c:\mydatabase.sdf"); return this.db_m.TestTable.Select(test = new Item() { .... } } I've read that Linq to SQL works with Sql Compact, is there some other configuration I need to do?

• Using DockPanel Suite's XML saving with My.Settings

  - by Cyclone

  In vb.net, how can I use SaveAsXML and LoadFromXML (DockPanel Suite functions) with My.Settings? I know there is a way to save it to a stream, but I don't know enough about System.IO to do this. DockPanel Suite: http://sourceforge.net/projects/dockpanelsuite/ I would very much prefer to store configuration using My.Settings instead of as an XML file. Thanks for the help! EDIT: Since the only person to answer so far has since deleted their answer, I feel I should explain further: Those two methods can both accept a stream object, but I have not used System.IO enough to know how to properly initialize a stream, let alone get a string out of a stream. EDIT: Googling has gotten me nowhere. EDIT: Still waiting for this. I've tried everything...

• Configuring Team System Code Analysis via a FxCop rules file

  - by Ian G

  Is there anyway to configure the code analysis rules in Visual Studio Team System to match those in an FxCop configuration file and keep them in sync automatically? Not all the developers on the team have TS so keeping the rules we are currently running in an FxCop file is required so everyone can run the same set, but it would nice for those with to be able to run them in the IDE. We're introducing static analysis to an existing project so turning on everything now isn't a useful option. (We are not using Foundation Server for source control, if that makes any difference.)

• XAML Serialization object not using asp.net shadow copy

  - by mrwayne

  Hi, I'm having a problem where i use the XAML serializer / deserializer for a configuration type file that i have. The problem that i'm getting, is that the XAML serializer is returning objects from the assembly in the /Bin directory, while the rest of the web application is using assembly's stored in the ..../Temporary Files/.. directory. Is there any way to prevent this from happening? Is this a bug in the XAML serializer / assembly loading routines? Every time i compile i need to stop and start the asp.net application so the shadow copy and the bin are exactly the same file. Even when not making a change to the dll and recompiling still causes the problem. Any thoughts on how to get around this problem? Currently i've tried turning shadow copy off, but then i have the same problem of needing to shut down / start up the web app every time i compile. Help!

• Trying to INstall PHP on windows 7 ultimate with IIS6

  - by Jack

  I am trying to install php on my windows 7 machine. I have installed IIS 6.x and I have also installed php. I used this tutorial http://blogs.iis.net/bills/archive/2006/09/19/How-to-install-PHP-on-IIS7-_2800_RC1_2900_.aspx The only thing I didnt understand is this part: 4) Install IIS7, making sure you install the ISAPI Extension component (for PHP-ISAPI - which is what I use) or the CGI component (if you prefer CGI) during IIS installation (ISAPI and CGI are not installed by default) Now when i go to localhost I get an error. HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. 4: <handlers> 5: <add name="PHP" path="*.php" verb="*" modules="FastCgiModule" scriptProcessor="C:\web\php5\php-cgi.exe" resourceType="Unspecified" /> 6: </handlers> Also php pages do not work in IE, please help

• Problem creating ObjectContext from different project inside solution.

  - by Levelbit

  I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

• Canvas context used but not updated on canvas

  - by John Doe

  I am developing an small html5 game, where I have the following code: if(object.blocks){ var blocks = object.blocks, that = this; each(blocks,function(index){ that.blocks.push(new Block(this[index])); }); } I receive an object with some configuration and instantiate blocks with it. It works fine, but the Block class has an method, called draw: this.draw = function (ctx){ if(ctx){ var colors = ['#FF0000','#FFFF00','#0000FF','#00FF00'], color = Math.round(Math.random() * colors.length-1); ctx.fillStyle = colors[color]; ctx.fillRect(this.x,this.y,this.width,this.height); } }; It was working before I moved it into the Block class, but now it draws nothing. This is the code that calls draw: render: function(ctx){ each(this.blocks,function(index){ this[index].draw(ctx); }); } The context comes from the html page, from the main canvas.

• Cannot add library in VC++ 2008: My System is Different

  - by jfm429

  Hopefully someone can tell me what's going on here. I'm trying to link to gdiplus.lib and I tried to go to "Properties - Linker - Input - Additional Dependencies" to add the library but I do NOT have that section. I'm using Visual C++ 2008. Here's what I see: Common Properties Framework and References Configuration Properties General Degugging C/C++ Librarian Resources XML Document Generator Browse Information Build Events Custom Build Step I've checked every subcategory and there is NOT a "Linker" section or an "Input" section. Once again, this is Visual C++ 2008 without any customizations or strange settings. I have a screenshot at http://drp.ly/13ma9l if anybody's interested. How come my Property panel is completely different than everyone else's? Typical Microsoft crap I suppose...

• Could not load file or assembly log4net or one of its dependencies

  - by Elie

  I've been asked to take a look at an error in an ASP/C# application with its Paypal integration. The error, shown in full, is: Could not load file or assembly 'log4net, Version=1.2.0.30714, Culture=neutral, PublicKeyToken=b32731d11ce58905' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) From what I understand, this means that the actual file located (that is, log4net.dll in my bin directory) does not match the version expected based on some assembly configuration. The problem I'm having is that I cannot locate where this file is being referenced. I have access to all the files in the web root directory of the site, and cannot locate any config files that reference this DLL. Where else might I need to look to determine what's causing the mis-match? As a note, I've made sure that the version of the DLL in the bin directory is up to date, but this does not seem to have resolved anything.

• How to load View from NIB into another NIB?

  - by Sheehan Alam

  I have two NIB's ParentViewController.xib ChildViewController.xib ParentViewController.xib contains a UIView and a UIViewController. ChildViewController.xib contains a UIButton I want ChildViewController.xib to load in the ParentViewController.xib's UIView I have done the following: Created @property for UIView in ParentViewController Connected File's Owner to UIView in ParentViewController Set UIViewController in ParentViewController's NIB Name property to ChildViewController in Interface Builder Set ChildViewController view property to UIView in ParentViewController I was hoping this would load ChildViewController into my UIView in ParentViewController but no luck. I did get the following warning, which could be the culprit: 'View Controller (Child View)' has both its 'NIB Name' property set and its 'view' outlet connected. This configuration is not supported. I also have added additional code in ParentViewController's viewDidLoad(): - (void)viewDidLoad { [super viewDidLoad]; ChildViewController *childViewController = [[ChildViewController alloc]initWithNibName:@"ChildViewController" bundle:nil]; childViewController.view = self.myView; } Any thoughts on why ChildViewController does not load in the UIView of ParentViewController?
