what about a simple select, which should always work (such as "select 1")? If a DbException is thrown, try reconnect...

You should provide more information. It heavily depends on data stored inside the database (such as images etc).

improved readability.

What are the errors? No one can help you without more details

Which operating system?

But doesn't it return same values if you have UPS connected to your desktop?

Did you tried explicit implementation of interfaces?

See my comment in Answer 3. Your solution is basically correct, but multiplication should be obtained using sizeof operator

Sorry - you should have: cbRequest = wcslen(message) * sizeof(wchar_t) because unicode characters are stored as multiple bytes.

You should be more specific

What exactly do you means by device callback event?

Try google...

Ok, thanks for clarification. But it's possible only with dynamic methods. Isn't it?

Simply read it to memory and send it thru your opened network stream...

There are for some interesting points in your post. Thanks for deep explanation :-).

But this is adding some overhead for big objects. You are creating a temporary copy and thereafter there is a check in std::swap STL function about the references.

Sorry, but I don't see big benefits about it...

Ok, if you want to be absolutely correct, you should also check reference in assignment operator against this pointer...

No, only assignment operator will be applied.

Did you try opening such amount in data in excel? I don't believe you will succeed...

You are right. Code fixed. Thanks.

If you are implementing POP3 yourself, why don't you use appropriate RFC?

be more specific

What do you mean by another instance of a method? It's a standard call. The difference is that you have same method accessed from two threads and two different stack.
If you will not modify shared data after you initialize shared object instance, you don't need synchronization (locking).
Main goal of synchronization is to keep objects in consistent and predictable state - image following situation:
1. you have an instance variable of value 3 (this.i == 3)
2. you read int variable from two threads into a local variable (lets say you have int i = this.i;)
3. you increment your local variable (i++);
4. you save new value back to instance member (this.i = i;)

I would expect value 5 but in this case you can quite easily get also value 4 (both threads may read value 3, increment and save back).

Please fix the last code sample

Reason for my vote of 1
Can't believe that I see this question.

Or the SQL command...

I suppose that you must use ONLY managed data types (it means only types available from VB/C# managed code). So if you are using an unmanaged one (such as HANDLE, PIPE_PTR etc.) it will not work.

Based on definition of the PIPE_PTR you can use IntPtr managed type or an integral one (UInt32, UInt64).

If your DLL is COM than it's better to use COM interop. Otherwise I would prefer the managed C++, which will allow you to have event delegates etc.

Hi, can you be more specific - on which system do you have installed VS2008?

As I know, libraries are named wsock32.dll and ws2_32.dll and they are part of the system (located in system32 folder). Link libraries (.lib) should be installed together with VS2008, but you must have selected C++.

Are you really looking for interpreter and not a compiler? And if you are looking for a compiler, can you be more specific regarding the target platform?

You had there () brackets. This means that you were allocating only single character and it was initialized to the value 5.

Sory.

It is used to prevent copying of objects at function calls or with the copy-initialisation syntax.

Following will not work with your original class.

Y M(void)
{
        Y y;
	return y;
}

B is not static class, you are using an instance of it - think it's as a namespace. It's same as sa.Text text = new sa.Text() or sa.Text.B b = new sa.Text.B()

That's exactly what am I writting about - it's a speciality of class V - it can access private members of the top class A.

Not sure if I understand what are you asking about.

The nested class V is a standard class, which can be instantiated based on its vibility modifiers.
It has only one speciality - if you have an instance of the top class A, you can access its private members from the V's code.


class A
{
private int i;
public A()
{

}
public class V
{
int ii;

public V()
{
A a = new A();
a.i = 10;
}
}
}


It's more like an additional namespace.
