    - Clearing large arrays from memory The GC isn't interested in reclaiming all available memory. This would be slow and wasteful. Instead the GC's goal is to ensure that enough memory is available to handle any memory allocation requests. As a result there are lower limits as to how much memory you can expect to recover during a GC. 15MB on a 512MB machine isn't much so I wouldn't worry about it. If you had allocated 256MB and the GC didn't recover any of it then I'd blame it on an outstanding reference. Now as to where the 15MB came from. At least part of it comes from the various objects that are sitting on the callstack (the event arguments for example). When you do a GC all objects that aren't freed move to the next generation. Therefore that event arg you allocated before calling btnClick is now in G1. Therefore it won't get freed by the GC for a long time (if ever) since G0 is generally sufficient. This is the primary reason why you should never force a GC. This applies to any of the other objects (even locals) that you allocated in any previous stack frame. So, taking this example a little further imagine that you modified the code as follows: private void btnClick ( object sender, EventArgs e ) { int[] arr = new int[1204]; DoSomething(); arr = null; } private void DoSomething ( ) { GC.Collect(); } The first function allocated 1MB of memory. The second function forced a GC. Since the array was still in use that 1MB is now moved to G1. Until the GC tries to fill a memory request and can't by dumping G0 objects that 1MB will remain around in memory even though you set it to null. Normally you would expect the G0 objects to go away pretty quickly. That is the way generational garbage collection works.

    - Creating .EXE? Hi, in visual studio you can create 2 main kind of applications Windows Applications or Console Application. Sounds like you need a minimal UI, if at all so you can create a Console Application. That will generate an EXE and will display if you want a window like a command prompt. All you need to do in Visual Studio after you create the project is compile the project and it will generate an EXE for you. Mark.

    - "object reference is required for the nonstatic field, method, or property 'Namespace1.Class2.Method2(object)" Hi, in Method1, you are adding the Class2. M ethod2 as the method the delegate should call, but this is syntax to call a static method. A static method lives at the class level and is shared by all instances of the class, you need to modify your Method2 signature to include the static keyword i.e. public static void Method2(object w){ ..... If you don't want to make that static then you will need to create an instance of Class2 inside your Method1 (or somewhere else inside Class1 and pass that to the delegate i.e. Class2 myClass2 = new MyClass2(); Thread begin =new Thread(new ParameterizedThreadStart( myClass2 .Method2)); Mark.

    - VS2005 Crashes after Rebuilding the Solution Hi Bastian, Thanks for the bucket ID info in the message. That is very helpful and cuts down the investigation time in half for us. Looking at the bucket ID on our internal server, I am seeing that there are 4 issues that can cause this bucket. I want to narrow it down to the one that is responsible for the crash you are seeing. Can you please do the following the next time it crashes 1) make a reg file out of the following and run it. Make sure you set a local path to "DWFileTreeRoot" Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PCHealth\ErrorReporting\DW] "DWNoExternalURL"=dword:00000000 "DWNoFileCollection"=dword:00000000 "DWNoSecondLevelCollection"=dword:00000000 "DWFileTreeRoot"= ".\\Dumps" "DWReporteeName"="" 2) Then Click on the "Send error report" on the dialog you see after the crash 3) This will store the dump file at the location you mentioned for "DWFileTreeRoot" instead of sending it to the MS server 4) Open the .dmp file in VS and hit F5 and when it breaks, open callstack window and post back the top of the callstack. This will help me nail down the issue in the bucket and I will open a bug for the same for us to fix here.

    - Corrupted C# compiler? I would recommend you try this on a second computer. As any programmer knows its usually the last thing installed or uninstalled which affects a program. If you can get it working on the other computer, then that means something about its environment is causing the problems. Otherwise, for nothing else but peace of mind, uninstall VS2005 and reinstall it with SP1 and rebuild and see if the same happens.

    - Calling external dll which exposes a class IClass must be a COM class to be supported in C#, otherwise you have to write a C++/CLI (Managed C++ if you're in VS2003) wrapper for that class so managed code can make use of it. If it's a COM class, if you add a reference to the binary for that COM object you should then have access to an IClass that C# will recognize.

    - Can't see form anymore..... panic! If you run the form do the controls display properly If not then I would wager that maybe you inadvertently set the size, location or visibility of the controls such that they are no longer visible. Also be sure that every BeginUpdate call in the InitializeComponent function has a matching EndUpdate otherwise the controls won't render properly. If the controls do display properly then I'd wager that something went wrong in the dsigner.

    - Question on architecture for an Active Directory API I'd like to create a wrapper API for active directory which has a member function which accepts a structure as a parameter and outputs the structure as the return value. The structure would be customized by the developer who is using the API to include only data members which the developer requires. I'd like the member function to determine what data members the structure contains and, thus, which data to pull from the active directory. (I figure this will speed processing time as the developer using the API will only have to make one trip to the member function and get all the required data at once.) I figure that the member function will accept a parameter of type object to represent the structure and use reflection to determine what data members it contains.

Hello!

Can I prevent Visual C# IDE (Visual Studio 2005 Pro) from putting classes/interfaces inside the subnamespace with the same name as the folder it is created in

I.e. C# Class Library DLL has a subfolder called "Foo" and classes created in the folder Foo automatically gets in DefaultNamespace.Foo.

Regards, Per Edin

I haven't found a way around that other than to use the ReSharper add-in from JetBrains.
