Hi
When you want a full fledge profiler with some extra features the I would suggest you try ANTS Profiler. However, you may try any of the following available tools:

1- NCover
2- NDepend
3- ANTS Profiler
4- .NET Memory Profiler
5- AQtime .NET Edition 2 - Automated Profiling and Debugging
6- Compuware DevPartner Studio Professional Edition
7- Compuware DevPartner Profiler
8- Allocation Profiler
9- CoverageEye.NET
10- NProf

Hope this helps Smile | :)

Hello everyone,

For the following code, it is correct to say that,

1. obj1 will be instialized when .NET Runtime loads class Foo and before any instance is created?

2. obj2 will be created each time we create an instance of Foo, and obj2 will be called before constructor?

My question is whether my understanding (1) and (2) are correct?

class Foo
{
    static private object obj1 = new object();
    private object obj2 = new object();
    public Foo()
    {
    }
}

thanks in advance,
George

Yeah, I believe so. You can write your own classes in place of the objects, and check it for yourself.

No. The obj1 member will be initialised before any member of the Foo class is used, but not necessarily when the assembly is loaded.

Yes.

Despite everything, the person most likely to be fooling you next is yourself.

From MSDN:

Additionally, the Hide method of the TabPage will not hide the tab. To hide the tab, you must remove the TabPage control from the TabControl..::.TabPages collection.

My thoughts too, could you perhaps store the removed object locally somehow?

Hello everyone,

For Windows Service, for example class Service1 is the main class of my service application, which derives from ServiceBase. I am wondering whether it is possible that two concurrent access to the following 3 cases?

1. the constructor of Service1;
2. OnStart method of Service1;
3. OnStop method of Service.

If yes, I need some synchronizaton control in them. If yes, in what situation the three methods will be called concurrently? We are able to start/stop the same service with different instances (processes) at the same time?

thanks in advance,
George

I'm not really an expert here, but I think that since Windows Services are all handled in a unique central place, there is no need to worry about the constructor/OnStart/OnStop methods. However, you have to worry about access to other resources your service might use during normal operations.

Thanks Dario,

Is it possible that two different instances (processes) for the same Windows service will be started and run at the same time?

George

No, unless you create two different services that point to the same executable.
Anyway, a service can be started only once, even using command-line tools or WMI.

On the other hand, two processes do not implicitly share memory, so you would not have concurrency problems even in the case a service was started twice, except for file access I guess (remember that all the Windows API are reentrant).

Good answer, thanks Dario!

So, I think the conclusion is there is no need to consider concurrent issue here.
