• .NET Development application idle state handling

  hi, I'm writing an application that display in .net MDI (c++) style 3d models (from my own file format), with some animation in it, so I need to handle my application idle state. I can write idle event handler, but it's not exactly what I need, because it only execute once when application turns to idle state. I need some function that is executing all the time when idle state is active, or I need to know when application is going to exit idle state, in this case I could make some loop and check when I need to break this loop and end execution of idle state handler. or maybe there is some other solution thanks for reply.

• Visual C++ creating exe's and running them

  this is probably an extremely obvious question... but when i type in my code How do i run it I have tried "building" my project but then i don't know how to run the app once it has been built/ Hmmm That's weird man. And the project built fine   Typical MS products. The whole thing has me pulling my hair out. Programming in Linux is so much easier. I have found that building the Help contents code examples consistently provokes unexplicable errors. I think I shall be returning to Unix soon. ...Show All

• Software Development for Windows Vista Questions about my ASP.NET scenario

  I have some simple question about my asp.net scenario. My web app has to manage a thesis request, from a student against a teacher. For the moment I consider a simpler view of the workfow. A student can do a request of a thesis and a teacher can approve or reject the request. We consider only this simple scenario. The questions are: 1)I have something like StudentService and TeacherService. Do I add these services at the runtime each time before a workflow instance is started (only when the student request the thesis) or I have to add them to the webconfig of my web project and then siply do a wfr = WorkflowRequestContext.Current.WorkflowRun ...Show All

• Visual C# Serilization of a generic List of a custom type, how?

  Well, hi all. This is my first post here, since I haven't been able to find the required information anywhere else, so I will give it a go here... I am trying to make a generic list of a custom type and serializing it. Sounds simple but apparently its not. I have now boiled the problem down to a very simple example, and tried to get consistency in the problem. The problem occur every time the assembly holding the custom type is rebuild. Naturally, I can make a list of some .NET type and it works, and I think thats because the .NET assemblies are not rebuild in between. Is it a feature in .NET that it is not possible to do generic list ...Show All
