  • SPNavigationNode.IsVisible property not working as expected.

    - by Manish
    My code is as under: using (SPSite spSiteTest = new SPSite(serverUrl)) { using (SPWeb mySite = spSiteTest.OpenWeb()) { SPNavigationNodeCollection quickLaunchNodes = mySite.Navigation.QuickLaunch; SPNavigationNode navQuickNode = new SPNavigationNode("Title", "www.stackoverflow.com", true); foreach (SPNavigationNode node in quickLaunchNodes) { if (node.Title == navQuickNode.Title) { node.Url = navQuickNode.Url; node.IsVisible = isVisible; node.Update(); //mySite.Update(); return; } } quickLaunchNodes.AddAsFirst(navQuickNode); } } I want to hide a quick launch node but using the above code, it's not working. :( Am I missing something?

  • Silverstripe | Internal Server Error

    - by Benedikt R.
    Hi! Silverstripe is running on my since a few weeks. Recently, I get an Internal Server Error message when I try to access the admin area. Having a look in the server's error logs, I discovered following hint: [Mon Apr 05 12:15:26 2010] [error] [client ...] Premature end of script headers: main.php I already was refered to this site: What does the 'premature end of script headers' error mean? But does anybody had this problem in connection with Silverstripe? Would make it much easier to restrict the scope from where the error is caused. Regards, Benedikt

  • Windows Workflow Foundation 4 (WF4) ReHosting

    - by Russ Clark
    I've been looking at the possibility of ReHosting a WF4 Workflow to be used to debug running Workflows. All the posts and samples I've seen regarding WF4 Rehosting are using a WPF application to initially Host the Workflow, and then use the WorkflowDesigner in ReHosting it. Is there any way to Rehost a Workflow that was hosted in a non WPF application, like ASP.Net MVC?

  • Run WCF ServiceHost with multiple contracts

    - by Sam
    Running a ServiceHost with a single contract is working fine like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.Open(); Now I'd like to add a second (3rd, 4th, ...) contract. My first guess would be to just add more endpoints like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.AddServiceEndpoint(typeof(IMyService2), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService2"); servicehost.Open(); But of course this does not work, since in the creation of ServiceHost I can either pass MyService1 as parameter or MyService2 - so I can add a lot of endpoints to my service, but all have to use the same contract, since I only can provide one implementation? I got the feeling I'm missing the point, here. Sure there must be some way to provide an implementation for every endpoint-contract I add, or not?

  • Google app engine issue 777 particular solution?

    - by Niklas R
    I use 64.202.189.170 (godaddy) for a HTTP access to a www...on google app engine like GAE issue 777 so that a blank subdomain forwards to www.domain I get the blank to respond by output "This website is temporarily unavailable, please try again later. " There's info about this issue here http://knol.google.com/k/google-apps-discussion-group#view and here http://code.google.com/p/googleappengine/issues/detail?id=777 Since I managed to do it with a .com domain (The godaddy DNS hosted gralumo.com correctly responds to www..) I now want to do it with an off-site DNS managed domain getting the following info about servers: $ ping montao.com.br PING montao.com.br (64.202.189.170) 56(84) bytes of data. 64 bytes from pwfwd-v01.prod.mesa1.secureserver.net (64.202.189.170): icmp_seq=1 ttl=113 time=188 ms 64 bytes from pwfwd-v01.prod.mesa1.secureserver.net (64.202.189.170): icmp_seq=2 ttl=113 time=188 ms ^C --- montao.com.br ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1001ms rtt min/avg/max/mdev = 188.459/188.692/188.926/0.493 ms ubuntu@ubuntu:~$ ping www.montao.com.br PING ghs.l.google.com (74.125.43.121) 56(84) bytes of data. 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=1 ttl=56 time=30.2 ms 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=2 ttl=56 time=28.0 ms 64 bytes from bw-in-f121.1e100.net (74.125.43.121): icmp_seq=3 ttl=56 time=24.2 ms ^C --- ghs.l.google.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 24.201/27.522/30.282/2.514 ms So it looks to me these are the same IP numbers whether or not it's off-site DNS. It's just that it works for one domain and not the other. Could it be just resetting the appspot app ie removing and adding it? Can you recommend how to proceed? Thanks in advance

  • Redirect folder to different server

    - by yuval
    I know you can redirect subdomains to a different server, but can you do the same with folders? Say I have example.com. I can redirect mysubdomain.example.com to a different server, but can I redirect example.com/mysubdomain to a different server? I'd like to host a rails app in that folder on a site that runs php while still maintaining good search engines ratings (by not creating a sub domain which in my experience in recognized as a different site). Any help? Thanks!

  • Using HttpClient with the RightScale API

    - by Ameer Deen
    I'm trying to use the WCF Rest Starter Kit with the RightScale's Login API which seems fairly simple to use. Edit - Here's a blog entry I wrote on using Powershell to consume the API. Edit - Created a generic .NET wrapper for the RightScale API - NRightAPI It's exactly as simple as it looks while using CURL. In order for me to obtain a login cookie all I need to do is: curl -v -c rightcookie -u username:password "https://my.rightscale.com/api/acct/accountid/login?api_version=1.0" And I receive the following cookie: HTTP/1.1 204 No Content Date: Fri, 25 Dec 2009 12:29:24 GMT Server: Mongrel 1.1.3 Status: 204 No Content X-Runtime: 0.06121 Content-Type: text/html; charset=utf-8 Content-Length: 0 Cache-Control: no-cache Added cookie _session_id="488a8d9493579b9473fbcfb94b3a7b8e5e3" for domain my.rightscale.com, path /, expire 0 Set-Cookie: _session_id=488a8d9493579b9473fbcfb94b3a7b8e5e3; path=/; secure Vary: Accept-Encoding However, when I use the following C# code: HttpClient http = new HttpClient("https://my.rightscale.com/api/accountid/login?api_version=1.0"); http.TransportSettings.UseDefaultCredentials = false; http.TransportSettings.MaximumAutomaticRedirections = 0; http.TransportSettings.Credentials = new NetworkCredential("username", "password"); Console.WriteLine(http.Get().Content.ReadAsString()); Instead of a HTTP 204, I get a redirect: You are being <a> href="https://my.rightscale.com/dashboard"redirected <a> How do I get the WCF REST starter kit working with the RighScale API ?

  • Shift-reduce: when to stop reducing?

    - by Joey Adams
    I'm trying to learn about shift-reduce parsing. Suppose we have the following grammar, using recursive rules that enforce order of operations, inspired by the ANSI C Yacc grammar: S: A; P : NUMBER | '(' S ')' ; M : P | M '*' P | M '/' P ; A : M | A '+' M | A '-' M ; And we want to parse 1+2 using shift-reduce parsing. First, the 1 is shifted as a NUMBER. My question is, is it then reduced to P, then M, then A, then finally S? How does it know where to stop? Suppose it does reduce all the way to S, then shifts '+'. We'd now have a stack containing: S '+' If we shift '2', the reductions might be: S '+' NUMBER S '+' P S '+' M S '+' A S '+' S Now, on either side of the last line, S could be P, M, A, or NUMBER, and it would still be valid in the sense that any combination would be a correct representation of the text. How does the parser "know" to make it A '+' M So that it can reduce the whole expression to A, then S? In other words, how does it know to stop reducing before shifting the next token? Is this a key difficulty in LR parser generation?

  • Settings up a Mercurial server on IIS 6

    - by TheCodeJunkie
    Hi, I've set up a Mercurial server on a Windows 2003 / IIS 6 machine and when I try to pull the repository I get the following sequence requesting all changes adding changesets adding manifests adding file changes transaction abort! rollback completed abort: premature EOF reading chunk (got 91303 bytes, expected 1542634) I've tried pretty much everything I can think of, but with no success. I followed the steps of Jeremy Skinners guide on doing it for IIS7, but on an IIS6 server. I found a post where the author was experiencing the same issue, but was unable to find a solution. So far it looks like the solution is to migrate to Apache or upgrade to Windows 2008/II7 .. but if someone knows how to solve this, please let me know

  • Transition domain to new web host without waiting for DNS propagation

    - by jcmoney
    I was considering switching to Amazon EC2 to host my website to handle more traffic. It seems like I would have to update DNS records to point to the new server but I was wondering if there was a way to avoid having to wait for the new DNS record to propagate. Putting the code on both hosts would not work for me since the app writes to a database pretty frequently. I thought about just using a meta redirect or php redirect on the old host to redirect to the new host ip but was wondering if there's a better more accepted way of doing this.

  • Workflow Service host not publishing Metadata.

    - by jlafay
    Still hacking away with extreme persistence at WF services hosted outside of IIS. I'm now having issues with my WF service publishing metadata. Can someone take a look at my code and see what step I'm missing? The few tutorials that I've stumbled across for my scenario make it look so easy, and I know it is. I'm just missing something ridiculously simple. Here's my current trial code: const string serviceUri = "http://localhost:9009/Subscribe"; WorkflowServiceHost host = new WorkflowServiceHost( new Subscribe(), new Uri(serviceUri) ); SubscriberSvcHost.AddDefaultEndpoints( ); SubscriberSvcHost.Open(); Subscribe() is an activity that is coded in an xaml file and contains simple receive and sendreply activities to test out my hosted workflow service. It is NOT a xamlx (WF service) file. Seems like this should be simple enough to work but when I start the application and the service fires I get this message in my browser when navigating to the URI: "Metadata publishing for this service is currently disabled." Shouldn't adding the default endpoints provide enough metadata and description to satisfy the service init and then go into its wait for message state?

  • Hosted full text search solutions?

    - by James Cooper
    Does anyone know of companies offering SaaS full text search? I'm looking for something that uses Lucene, solr, or sphinx on the backend, and provides a REST API for submitting documents to index, and running searches. I could build my own EC2 AMI, but I'd have to configure EBS and other stuff, monitor it, etc. Curious if someone has already done all this and would charge per MB/GB indexed. thank you. -- James

  • How to use prettify with blogger/blogspot?

    - by billpg
    Hi everyone. I'm using blogger.com to host some texts on programming, and I'd like to use prettify (same as stackoverflow) to nicely colour the code samples. How do I install the prettify scripts into the blog domain? Would it be better (if indeed its possible) to link to a shared copy somewhere? I have webspace on a different domain. Would that help? Many thanks.

  • mosso versus gogrid which is better?

    - by goodwill
    I have reasonable experience to manage my own server, so gogrid style management is not a problem. But seems mosso is a tag cheaper somewhat- except the very difficult to access compute cycles terms. Anyone could share about this would be very welcomed.

  • How do I design the file storage issue?

    - by user102533
    I am working on an application that creates video files and stores them in a folder in the C:\ drive. I speculate that there will be a large number of these files in the future and we would run out of disk space at some point of time (on our VPS). When the time comes that we have to upgrade, we either plan to use one of the Cloud providers to store files or our existing provider can add another disk (say D:\ drive). Either way, I would want to design the app now in a way that in future, moving to different locations would not be an issue and would be transparent to the end user. The code that creates these files supports 2 ways: myObj.SetOutputToDisk(<path to store>); or myObj.SetOutputToMemoryStream(ms); If we go with the Cloud architecture, I assume we might have the following combination: Cloud Files + Existing VPS or Cloud Files + Cloud Windows Server Given the unknowns at this time, how would I go about designing this?

  • WCF Self Host Service - Endpoints in C#

    - by Kyle
    My first few attempts at creating a self hosted service. Trying to make something up which will accept a query string and return some text but have have a few issues: All the documentation talks about endpoints being created automatically for each base address if they are not found in a config file. This doesn't seem to be the case for me, I get the "Service has zero application endpoints..." exception. Manually specifying a base endpoint as below seems to resolve this: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.ServiceModel.Description; namespace TestService { [ServiceContract] public interface IHelloWorldService { [OperationContract] string SayHello(string name); } public class HelloWorldService : IHelloWorldService { public string SayHello(string name) { return string.Format("Hello, {0}", name); } } class Program { static void Main(string[] args) { string baseaddr = "http://localhost:8080/HelloWorldService/"; Uri baseAddress = new Uri(baseaddr); // Create the ServiceHost. using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress)) { // Enable metadata publishing. ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15; host.Description.Behaviors.Add(smb); host.AddServiceEndpoint(typeof(IHelloWorldService), new BasicHttpBinding(), baseaddr + "SayHello"); //for some reason a default endpoint does not get created here host.Open(); Console.WriteLine("The service is ready at {0}", baseAddress); Console.WriteLine("Press to stop the service."); Console.ReadLine(); // Close the ServiceHost. host.Close(); } } } } I still think I'm doing something wrong as I don't get the normal "This is a web service...etc..." page when I load up the url How would I go about setting this up to return the value of name in SayHello(string name) when requested thusly: localhost:8080/HelloWorldService/SayHello?name=kyle Do I have to create an endpoing for the SayHello contract as well? I'm trying to walk before running, but this just seems like crawling...Service has zero application endpoints...

  • Access DotNetPanel/WebsitePanel Enterprise Server from outside the loopback address

    - by Ryan French
    Hi Peoples, I am currently investigating integration of DotNetPanel/WebsitePanel with a website that is running ColdFusion. The issue I have come across is that it seems WebsitePanel only allows access to the Enterprise Server (where the web services are that I need access to) when the request is coming from the same physical machine (i.e. on the loop-back address 127.0.0.1). This unfortunately doesnt really work out too well with our current setup as we have our ColdFusion server running on one machine and WebsitePanel running on another. Does anyone have any suggestions as to how we can change this? Currently we are investigating writing a transparent proxy server that will sit on the portal machine and pass requests between the two sites, but that is less than ideal.

  • How to run PowerShell scripts via automation without running into Host issues

    - by Scott Weinstein
    I'm looking to run some powershell scripts via automation. Something like: IList errors; Collection<PSObject> res = null; using (RunspaceInvoke rsi = new RunspaceInvoke()) { try { res = rsi.Invoke(commandline, null, out errors); } catch (Exception ex) { LastErrorMessage = ex.ToString(); Debug.WriteLine(LastErrorMessage); return 1; } } the problem I'm facing is that if my script uses cmdlets such as write-host the above throws an System.Management.Automation.CmdletInvocationException - Cannot invoke this function because the current host does not implement it. What are some good options for getting around this problem?

  • Connecting to a self hosted WCF service from a Flex application - policy issues

    - by James S
    Hello, I am trying to accomplish the following: I wrote a Flex application that is trying to connect to a WCF service hosted on the clients computer. I also wrote a windows forms application for the client to run. This application exposes a self-hosted WCF service that the Flex application is supposed to connect to. This works fine if I'm loading the Flex application from my local IIS. The problem starts when the Flex application is hosted on a different domain. When this occurs, the flash player requires a crossdomain.xml policy file on the clients computer. I also managed to expose the crossdomain.xml on the clients computer using another WCF self-hosted service and WebHttpBinding on the clients computer. This also works fine. My problem is that the flash player requires that the crossdomain.xml or a meta policy file will be in the root directory of the domain. If I used my WCF service to expose something on the root directory of the clients computer I will run over any existing web server capabilities the client has on the computer (such as IIS). I know it's a bit complicated scenario, but any help would be appreciated. Thanks!

  • Commercial use of open source software

  • Rackspace Cloud Sites: Compute Cycles exploding. Very expensive.

    - by Jaap
    Hi All, Since last week my compute cycles (CC) went through the roof (Rackspace Cloud Sites). Normally I stay under the 10,000 cycles per month . Now this month I already have more than 75,000 compute cycles. I don't have more visitors and I did not change anything in the code. I looked in the raw log files, that didn't help either... This explosion of CC already costs me more than 750 USD right now. And still counting. Anyone know what to do? I have contacted Rackspace last week. But still no solution/answer.... Looks like Rackspace is liking the money! Help! Thanks.
