Re: Playing nicely with ServicePointManager.ServerCertificateValidationCallback
Thanks, Corneliu. Didn't think of using an AppDomain to circumvent the static nature of the callback - good idea! Thanks, Joe. On Tue, Dec 13, 2011 at 12:06 PM, Corneliu I. Tusnea corne...@acorns.com.au wrote: Joseph, Firstly you should never (for production use) hook onto that method. It's a stupid design from MS to even have that method available as a static for the clear reasons you already identified (racing conditions mostly). The best way to play nicely is to start your plugin (or some part of it) inside a new app domain. The app domain will have its own ServicePointManager that you can hook onto without worrying you mess up with the rest of the application. Once done you can tear-down the app domain. If you need it for a longer time just keep that AppDomain live until the end of the app pool. Corneliu. On Tue, Dec 6, 2011 at 3:27 PM, Joseph Clark jcl...@atlassian.com wrote: Hello list! I have a requirement to relax SSL certification validation on certain web requests in my application. I know that I can do this by setting a custom delegate on the ServicePointManager.ServerCertificateValidationCallback property - which works fine. The problem I have is that I am not in full control of the host application - I am writing a plugin package that gets hosted in a 3rd party IIS application. Is there a way I can achieve what I'm after whilst still remaining a 'good citizen' in the host app? I have written the delegate so that it only performs my custom validation when it matches the request URI to the URI I expect (otherwise performing the default check), and I only register the callback for as long as I need it during the execution of a single method before setting it back to the original value. Even so, this is still vulnerable to race conditions if there is another request executing concurrently, and my code would be vulnerable to other code overriding the certificate validation callback in a similar manner. Any suggestions on how I can make this more robust? Examples and samples for this API on the Internet are mostly shocking, encouraging developers to just set the callback and return true (ie. no validation) with no discussion of the pitfalls this entails. Cheers, Joe.
RE: VB6 calling modal .net dialog
Did you try the forms interop toolkit ? http://msdn.microsoft.com/en-us/vstudio/bb419144 Hey now that's really interesting. The trouble is the web page doesn't explain how it works. I'll install the MSI and see if it has technical information on what it does. I'm wondering if it avoids COM registration. Failing that, I would have tried the .NET UI as a user control ;) Yes, we're not going to try and make VB6 call .NET Forms (separate windows). Our first option was to write everything but the UI in .NET, leaving only a thin shell of a UI in VB6. Now we have a second option ... if this Interop kits works well then we can perhaps easily reuse complete .NET controls in the VB6 app and slowly phase it out. Greg

wcf nettcp reliable session 'duplicating' messages
calling wcf gurus (again) firstly, i've logged this on both microsoft connect and stackoverflow I have a nettcp wcf service with a CallbackContract for duplex communication using reliable sessions. After the session is established the server uses the callback channel to push several messages to the client: message1: 1024kb message2: 200bytes message3: 300bytes message4: 400bytes On slower connections (but still decent, say 20-40kb/sec) I observe the first message is received however subsequent messages are delayed for a period of time and using various networking utilities I established that the server *resends* message1 several times. Depending on the network speed it may resend as many as 5 times (the slower your link speed is). *If you change the bindings and remove reliableSession the problem disappears.* It looks like this is 'normal' behaviour from some things I've read but is causing havoc for people on slower connections (even 50kb/sec you get 'duplicate' messages) I have reproduced my issue in a test project with as few moving parts as possible. https://connect.microsoft.com/VisualStudio/feedback/details/713819/wcf-nettcp-reliable-session-duplicating-messages#details http://stackoverflow.com/questions/8487240/wcf-nettcp-reliable-session-duplicating-messages
