| Creating and ASP like string parser (5 replies) |
| microsoft.public.dotnet.framework.clr |
| I have the need to create an ASP like parser that can basically embed templated values into a document. The idea is to have something similar to the way the ASP/ASP.NET parser works so you can use expressions and codesnippets in the text document and embed them into the output. But it has to work with strings or file inputs independently from a Web interface. Before you say, why would you ever nee... |

| Hi, I've seen that in the global.asax file the session object is still nothing, so I can't access to all my session variables.I'm working in the Application BeginRequest method. Is there a way to do it? What could I use instead of? I also tried the context.items, but it seems to me like if every time i access the global.asax.vb file all the context resets. I'm I wrong or I have to store this data ... |

| Do I need to worry about dependency on runtime version? (4 replies) |
| microsoft.public.dotnet.framework.clr |
| Hi. When we write our class libraries, are we tied to a particular version of the run time? If so, does that mean, when we deploy our class libraries, we should also deploy the runtime that we built with? It doesn't make sense though because if that's the case, then the customers would potentially have so many versions of the .NET runtime after they install different .NET components/libraries from... |

| I can't cast my object to it's actual type. (2 replies) |
| microsoft.public.dotnet.framework.clr |
| Here is a small "Hello World" app that gets into trouble doing dynamic loading. It can dynamically load a child class without knowing the actual type but fails when casting a dynamically loaded type to what it truly is. I can't tell if this is a bug or a feature. Just unzip into \projects and open the "Solution". Thanks, JDA |

| Passing a parameter to Thread StartProcedure (3 replies) |
| microsoft.public.dotnet.framework.clr |
| It is my impression that in the .net framework, when you instantiate an object of type thread("spawn a new thread"), the only argument that you can give the constructor is the address of a function to start at. I assume that somewhere in the Thread Class source code there is a call to CreateThread() from the Win32API, or alternatively beginthreadex() from the C Runtime. Both of these functions tak... |

| Static Methods: Example of Bad practice? (5 replies) |
| microsoft.public.dotnet.framework.clr |
| I just ralized that I may have shot myself in the foot, so I'm looking for a reality check... If a class has a static method that accepts a parameter, what would happen to performance if the method was taking alot of hits under a heavy server load? Would this be a bottle neck? I'm thinking since statics are scooped to the class, that request to the static method would be synchronous accross ASP .N... |

| AppDomain loading and unloading issues (4 replies) |

The main reason I'm doing this is to be able to unload dynamic code I'm compiling on the fly. 1) Is it possible to load an assembly in another appdomain without going to disk? Seems all the methods for creating an instance require a physical assembly file on disk, while I have an assembly reference in memory and woul... |

| memory question (5 replies) |
| microsoft.public.dotnet.framework.clr |
| Hi there, As far as I've understood the .net garbage collector, it frees not referenced objects and moves the objects "behind" in memory, so there is no memory fragmentation. So I tried the following: I created three objects on the managed heap (let's call the a, b, c). I created pinned references (in C ) and stored the actual memory addresses in some DWORD variables. After the pin references are ... |

| INFO: Mysterious .NET Threads! (7 replies) |
| microsoft.public.dotnet.framework.clr |
| Hello to all! I had always been interested on how the .NET threads are managed by the OS. Afterall, from what the concept goes, each Win32 physical process can contain multiple AppDomains, which in .NET terms, is a logical process. And not only that, each AppDomain can contain multiple threads that are, again, logical in nature. So, the question I had always been pondering upon was how these "logi... |

| .NET Framework Version (5 replies) |

| Is there any way to tell what version of the .NET framework a specific app is running against? Say ASP.NET, for instance. How do I tell what version of the .NET framework ASP.NET is running against? This is not a constant since obviously new versions of ASP.NET can be released, and MS can theoretically release publisher policy files to bind to new versions of the framework (i think, right?). In an... |
