I cannot help, but you have my sympathy. These are the parts of development that make me want to jump out of a plane.

You're telling me. I can't even add the 4.0+ Chart Controls to my toolbox anymore in VS 2013. They're in my GAC and I can add references to the project but if I try and add them to my toolbox they're not in the list of available .NET components, I have to browse to the files or drag them onto the toolbar. The former produces a message telling me either the DLL is invalid or doesn't exist, depending on what version I try. The latter produces a default 'bing' sound and absolutely nothing else

This is after completely uninstalling and reinstalling VS and the .NET Framework.

Some of these chart widgets are on the main dashboard of the software so I can't even do any changes to that any more because even I changed something unrelated, the designer fucks the charts up.

I've had to go back to an older branch of the project on VS 2008 for now, but the other migrated version has a couple of months of work on other features on it, including changes to various forms, so including designer files, and I've no idea if it'll even be possible to merge that into the unmigrated VS 2008 branch without buggering up everything.

ultimately winforms designer work translates directly into .cs or .vb code generation. you SHOULD just be able to copy the code changes across if you do it textually or with some non-VS tool

Begby: Apr 7, 2005; Light saber? Check. Black boots? Check. Codpiece? Check. He's more machine than kid now.

I have an issue that is driving me absolutely bonkers.

I have a C# app that is running as a service on a windows server. It polls a bunch of different shopping cart web services on a fixed schedule.

For one particular client, it fails with a SSL/TLS error that the certificate is not trusted. This is only for that client, we can query that same exact service for other clients on their servers. The error only appears though after the service has been running for a couple of hours. If I shutdown the service and restart it, it starts working again for awhile.

- I have explicitly trusted their cert and the intermediary cert on the windows server where we run the C# service.
- When running the plugin using a unit test I setup and using the client credentials for their service, it works fine
- I have no SSL errors or anything when browsing to the client's website, it looks fine
- Rackspace looked at our server and claim it is all setup right

I am about to lose my mind since it works for an hour or so, then stops, and it is working fine for all of our 100+ other integrations that the service polls.

So when you say "client", the part that's failing is when the customer connects to your service from their own machine?

The first step would be reproducing the failure, even if you have to do it live. Then instead of just "not trusted" (which could be anything) you can take a look at the failure and see the exact reason it's not trusting the certificate.

Can the server download a CRL? Does it have access to the CRL? Sounds like it does a check after awhile and can't validate the chain or something.

One thing you can test is to download the certificate and use the windows Certutil utility to check if you can build the certificate chain.

It uses the exact same apis as .Net does so any error should also turn up in there.

Another thing: Is the service running as a user and does it have the rootcerts in its own cert store?

I have data I need to process with record times at nanosecond resolution (specifically, measured in nanoseconds since the start of the year the data was recorded in, stored as uint64). For now I just need to turn it into a human-readable date and time, like 2012 May 28 11:35:58.000045921 (edit: adjustments will need to happen later, but that's not an immediate requirement). I figured at first (being a .NET and C# newbie) that DateTime would be able to do it with some finagling, but I guess from google that it only can store down to the microsecond, chopping off the 921 nanos at the end there. (Apparently they're important. :shrug:

) (edit: or is it 0.1 microsecond? Anyway still two digits short in that case)

Do I have any options short of, say, making the DateTime with the microsecond precision out of the uint64 nanos, ToString()ing it, and just tacking nanos % 1000 to the end of the string? Strikes me as maddeningly clunky, even if it'd work for now.

DateTime precision only goes down to the 100 nanoseconds. If you just want to use the built-in formatting DateTime formatting options, then I would say to make a class that wraps DateTime (e.g. PreciseDateTime) to delegate .ToString() calls and use whatever level of precision you need.

It might be worth looking at NodaTime, too. I don't know if it has that level of precision, but since it's maintained by a notorious calendar nerd, I wouldn't be surprised if it does.

Thanks, I had a feeling it was gonna come down to that but I just wanted to make sure. I guess overriding all the calls I care about for actually manipulating those times won't be too awful.

Does anyone have any good SignalR resources? Or has anyone used SignalR and can provide some feedback? I'm trying to send messages with different subsets of a dataset to different clients and I'm not seeing any good guides on how to do that. As an example, I'd like to update stock quotes only for stocks in a given clients portfolio rather than just send all stock quotes and have the client decide which ones to display. I'm not sure that SignalR is the right method for this task but I wanted to play around with it and this seemed like a decent learning application to try.

I've only played with SignalR a little bit, but you should be able to create groups, then send messages to just members of that group.

# ? Jul 14, 2014 18:01

Bognar: Aug 4, 2011; I am the queen of France; Hot Rope Guy

SignalR groups might be able to do what you need, but I imagine you would want to handle choosing which client to send updates to yourself. Groups don't scale as well as users do, and I imagine you would have to set up a group for each ticker which users would join if they want subscriptions. With stocks, that means you'd have a ton of groups.

You should be able to use the PersistentConnection API to send messages to individual clients. You'll have to manually keep track of who should be receiving updates depending on the data, but this should work better than having the client subscribe to a large number of groups.

Well, after my previous posts, I can no longer add chart controls of any version to my toolbox in Visual Studio, to the point where I've had to install Windows and VS 2013 on a VM today in order to do anything.

Incidentally, on the VM, if targetting .NET 3.5, I can add chart controls to my toolbox and add them to a form in the designer and it seems but, but if I close and re-open the solution again, the designer freaks out in the same way as before, saying the types are undefined. Even though I added them in the same environment right before.

Targeting .NET 4, I can add the controls. At this point I think I might just force an upgrade on my users.

I've worked on something similar where I need to push out data from a data set where it's different content for each user. What I did was treat the user as a group using their ID as the group name and then build up the data that they should see and send just that in the update(I presume if you're dealing with user portfolios you have what they should see stored some how).

kingcrimbud: Mar 1, 2007; Oh, Great. Now what?

I'm trying to combine a few components of the Enterprise Library. In this instance, I want to implement some retry logic (Transient Fault Handling) but I want to add this in behind-the-scenes (via Unity Interception). I'm using interception elsewhere but I can't seem to figure out the syntax needed to add these two components together.

For interception, this will essentially be a no-op, but is where I can add my retry logic, within an IInterceptionBehavior:

code:

public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
{
    return getNext()(input, getNext);
}

Let's assume that I want to retry an awaitable service call, that takes in a single request object and returns a single response object:

code:

public async Response DoSomething(Request)

I've injected my RetryPolicy into my implementation of IInterceptionBehavior, which contains the Invoke method above. But how do I combine the two? it'd be along the lines of this, but a whole lot messier I'm assuming:

code:

public IMethodReturn Invoke(IMethodInvocation input, GetNextInterceptionBehaviorDelegate getNext)
{
    return this.RetryPolicy.ExecuteAsync(getNext()(input, getNext));
}

Anyone have experience with this?

tl;dr I know how to use Transient Fault Handling and Unity Interception, but don't know how to combine them together

For linqpad, so I can see the output. Otherwise it just runs and doesn't display anything.

What's happening in my app is apparently hyphenated DLNs arenot passing through the masking. However, the select SHOULD strip hyphens out first.

I can confirm that it works fine. It outputs "H012345678901" twice. gently caress them what are you expecting as output? You have a NullReferenceException in your Where clause. You should check String.IsNullOrWhiteSpace first and then run the Regex on your string.

The Dump extension is something in LinqPad to know what to output.

How did you keep the service alive to push changes to users? All of the examples that have used timers have been for SignalR 1.0 which registered the service in global.asax to keep the service alive. The 2.0 examples using OWIN startup seem to use RX. Ideally though, I'd like it not to be timed. As in I get a message with a quote tick that pushes to the hub/persistent connection which pushes to the client. However, it seems like SignalR doesn't support that or my RX skills aren't very strong.

var set = new HashSet<DataBean>();
set.Add(new DataBean("1234", "other data"));
set.Add(new DataBean("1234", "hello world")); // set now contains both objects, but the second Add should have failed

So, you want to quickly store and retrieve key-value pairs. Why are you not using a dictionary?

You'll need to override Equals I think

This is correct. HashSet first checks the hash, then checks for equality using the specified equality comparer (which will most likely be EqualityComparer<T>.Default which uses .Equals()).

But yeah, you should probably be using a Dictionary.

That had occurred to me, but wouldn't a dictionary's default action be to overwrite the data associated with an existing key with the new data? (edit: it throws an exception.) I want to keep the original. In particular, the only thing that changes with the new inserts is a timestamp, but I'm only interested in knowing the earliest timestamp.

Semantically, it's a set of these objects, and the 'Key' here is itself data, so I don't like splitting the object into Key / Value.

Ah, that clarifies.

Overriding Equals did work (thanks Betjeman!), but I was confused because I knew that Add (and Contains) were supposed to be O(1), so I figured that it had to be checking with GetHashCode(). Makes sense that it's done as a first pass.

Thanks all.

It was SingalR 1 that I used and I followed this guide: http://www.asp.net/signalr/overview/signalr-1x/getting-started-with-aspnet-signalr/tutorial-server-broadcast-with-aspnet-signalr

Essentially you create a Broadcaster that's a Singleton which holds onto all the information while your Hub just tells it about new connections etc.

Hey thanks. I think that example would be better to carry over into SignalR 2. Previous articles I read seemed to require a timer to be a registered object to keep the server alive which I'm not sure if I can do in SignalR 2.0 since it's not activated through a global.asax. I'm still playing around with setting up a pub/sub message bus because that would seem to fit a true quote stream scenario better than a timed update, but this is a good start too.

Can't say specifically about Sharepoint, but this stopped us dead trying to intiialise an old web service on a new machine yesterday:

The response we were getting was "cannot resolve <servername>" as well.

Fix was to give permission for the asp.net process to modify the Windows/Temp directory.

E: wrong url

That... looks like a completely different problem?
