use:

    Process P = Process.Start(sPhysicalFilePath, Param);
    P.WaitForExit();
    int result = P.ExitCode;

from [MSDN][1]


  [1]: http://msdn.microsoft.com/en-us/library/system.diagnostics.process.waitforexit.aspx

You can try the below code:

        Dim P As New Process
        P = Process.Start(info)
        P.WaitForExit()
        fichiersATraiter = P.ExitCode

Hope this helps :)



In my WPF application I have a `ListView` whose `ScrollViewer.VerticalScrollBarVisibility` is set to `Disabled`. It is contained within a `ScrollViewer`. When I attempt to use the mouse wheel over the `ListView`, the outer `ScrollViewer` does not scroll because the `ListView` is capturing the scroll events.

How can I force the `ListView` to allow the scroll events to bubble up to the `ScrollViewer`?

Let&#39;s look at a simple example:

    struct some_struct {
       std::string str;
       int a, b, c;
    }
    
    some_struct abc, abc_copy;
    abc.str = &quot;some text&quot;;
    abc.a = 1;
    abc.b = 2;
    abc.c = 3;
    
    abc_copy = abc;

Then abc_copy is an exact **copy** of `abc`.. how is it possible **without** defining *the = operator*?

(This took me by surprise when working on some code..)

Why does the = operator work on structs without having been defined?

Hi I am trying to do the following:
I have a process which can take parameters (digits)
and return the sum of these numbers

    Process P = Process.Start(sPhysicalFilePath, Param);
                    int result = P.ExitCode;

I get the return value from &quot;ExitCode&quot;
the problem is:
the program sometimes finishes his work before the process 
so when the program reaches this line 

    int result = P.ExitCode;
I got an exception ..
my question is how to wait this process until it finishes its work
sorry I forget to say that&#39;s I am working with C# language

I have a LINQ query which returns `IEnumerable&lt;List&lt;int&gt;&gt;` but i want to return only `List&lt;int&gt;` so i want to merge all my record in my `IEnumerable&lt;List&lt;int&gt;&gt;` to only one array.

Example :


    IEnumerable&lt;List&lt;int&gt;&gt; iList = from number in
        (from no in Method() select no) select number;


I want to take all my result `IEnumerable&lt;List&lt;int&gt;&gt;` to only one `List&lt;int&gt;`

Hence, from source arrays: 
`[1,2,3,4]` and `[5,6,7]`

I want only one array 
`[1,2,3,4,5,6,7]`

Thanks

I have interface `IResourcePolicy` containing the property `Version`. I have to implement this property which contain value, the code written in other pages:

    IResourcePolicy irp(instantiated interface)
    irp.WrmVersion = &quot;10.4&quot;;

How can I implement property `version`?

    public interface IResourcePolicy
    {
       string Version

              get;
              set;
          }

Is there an equivalent to F#&#39;s List.map function in C#? i.e. apply a function to each element in the list and return a new list containing the results.

Something like:

        public static IEnumerable&lt;TResult&gt; Map&lt;TSource, TResult&gt;(this IEnumerable&lt;TSource&gt; source, Func&lt;TSource, TResult&gt; funky)
		{
			foreach (TSource element in source)
				yield return funky.Invoke(element);
		}

Is there already a built in way or should I just write the custom extension?

This is concerning Windows XP processes.

I have a process running, let&#39;s call it Process1. Process1 creates a new process, Process2, and saves its id.

Now, at some point Process1 wants Process2 to do something, so it first needs to make sure that Process2 is still alive and that the user has not not killed it.

How can I check that this process is still running?
Since I created it, I have the Process ID, I would think there is some library function along the lines of IsProcessIDValid( id ) but I can&#39;t find it on MSDN

I was very confused but the following thread cleared my doubts:

[Multiprocessing, Multithreading,HyperThreading, Multi-core][1]

But it addresses the queries from the hardware point of view. I want to know how these hardware features are mapped to software?

One thing that is obvious is that there is no difference between MultiProcessor(=Mutlicpu) and MultiCore other than that in multicore all cpus reside on one chip(die) where as in Multiprocessor all cpus are on their own chips &amp; connected together.

So, mutlicore/multiprocessor systems are capable of executing multiple processes (firefox,mediaplayer,googletalk) at the &quot;sametime&quot; (unlike context switching these processes on a single processor system) Right?

If it correct. I&#39;m clear so far. But the confusion arises when multithreading comes into picture. 

1. MultiThreading &quot;is for&quot; parallel processing. right?

2. What are elements that are involved in multithreading inside cpu? diagram? For me to exploit the power of parallel processing of two independent tasks, what should be the requriements of CPU?

3.   When people say context switching of threads. I don&#39;t really get it. because if its context switching of threads then its not parallel processing. the threads must be executed &quot;scrictly simultaneously&quot;. right?

 My notion of multithreading is that:
Considering a system with single cpu. when process is context switched to firefox. (suppose) each tab of firefox is a thread and all the threads are executing strictly at the same time. Not like one thread has executed for sometime then again another thread has taken until the context switch time is arrived.

4. What happens if I run a multithreaded software on a processor which can&#39;t handle threads? I mean how does the cpu handle such software?

5. If everything is good so far, now question is HOW MANY THREADS? It must be limited by hardware, I guess? If hardware can support only 2 threads and I start 10 threads in my process. How would cpu handle it? Pros/Cons? From software engineering point of view, while developing a software that will be used by the users in wide variety of systems, Then how would I decide should I go for multithreading? if so, how many threads?

Threads &amp; Processes Vs MultiThreading &amp; Multi-Core/MultiProcessor : How they are mapped?

Recently, I have been asked a question in an interview what&#39;s the difference between a process and a thread. Really, I did not know the answer. I thought for a minute and gave a very weird answer. 

Threads share the same memory, processes do not. After answering this, the interviewer gave me an evil smile and fired the following questions at me:

Q. **Do you know the segments in which a program gets divided?**

My answer: *yep (thought it was an easy one) Stack, Data, Code, Heap*

Q. **So, tell me: which segments do threads share?**

I could not answer this and ended up in saying all of them.

Please, can anybody present the correct and impressive answers for the difference between a process and a thread?

How can my C# application check whether a particular application/process (note: not the current process) is running in 32-bit or 64-bit mode?  

For example, I might want to query a particular process by name, i.e, &#39;abc.exe&#39;, or based on the process ID number.
