• .NET Development Notify user of session timeout?

  Hi, I need to notify the user when the session times out and I supose I'm looking to solve two things. 1. I would like to warn the user a minute or so before a timeout occurs and allow the user to extend the session. 2. If the session times out, then I want to redirect the user to a "you're logged out page". How is this done Thanks! This isn't related to web services unless you built your own web services authentication. By default the session timeout for the ASP.Net forms authentication is 20 minutes. You could have a javascript counter on each page that warns them when the timeout is about to occur: window.setTimeout(myalertfunction, 19 * 60 * 1000) //warn after 19 minutes funct ...Show All

• Software Development for Windows Vista ScardAccessStartedEvent does not signal in Vista services - service hardening?

  Dear all, Migrating our core development platform to Windows Vista, one of our Windows services using smartcards is failing. We have debugged the problem and found that the event provided by the function ScardAccessStartedEvent does not receive notification. This event is supposed to signal when the SmartCard Resource Manager starts. As we have a WaitForSingleObject(event,INFINITE), the service hungs. Testing the same service as an ordinary executable ( registering with -regserver ) I can see it works properly. In XP it works properly both as an executable and service. I have read something about Service Hardening in Vista and I guess it may be caused by privilege reduction. So, I've created some code to enumerate the existing ...Show All

• Visual Studio 2008 (Pre-release) store ServiceSecurityContext.Current info

  This may sound strange but is it possible to save the ServiceSecurityContext.Current info so that I can retrieve it and use it later I have a scenario where the client subscribes itself via a subscription service in the host. The host resides in another machine. Later, another service from the same host tries to invoke a method from the subscriber's service. The trouble I'm having is with SSPI negotiation. When I try to invoke the client's method, I get a "SSPI negotiation failed" error. I think if I can tell the Host the client's ServiceSecurityContext.Current info, I won't be running into this problem. Thanks. I'm asking what identity executes ServiceHost.Open() on the two servic ...Show All

• Visual Studio Express Editions VB.NET or C++, Which is best?

  I want to start learning C++ and I want to know the type of applications that it is best at making and whether or not it is better than VB. "C++ is better when you deal with hardware, also the application that you write in C++ are faster than vb, but take much time to write applications, for example most of game developer prefer C++ over any managed code" I love VB. I really do do. C++ maybe faster since it's a native mode image, although CLR based assemblies maybe NGENed and converted to native mode cade, they are still dependent upon the CLR. The C++ image will be relatively small, rough, tough and able to run standalone BUT without additional libraries or APIs, it won't do much witho ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Can you edit a Model's vertices at runtime?

  Is it possible to edit the vertices contained in ModelMesh Like could I get the vertices, alter their position and set the data back in the collection I ask this because for the terrain object in my game, I want it to be deformable. I've been playing with the content pipeline and my custom importer / processor / writer writes the height data as a byte array. When the object is read back, an index buffer and vertex buffer are generated in the terrain class. The vertex buffer is specified with ResourceUsage.Dynamic which to my knowledge is the only way to make the buffer read / write enabled. I'm considering altering my custom content pipeline objects to create ModelContent objects instead of my current approach, but I will abandon that id ...Show All
