this should probably be

Because the CStringT == operator is overloaded to handle PCYSTR.

And i am getting an error code of 122(The data area passed to a system call is too small) in VS2008.

Possibly because that's the last value that was set (with SetLastError()). In other words:

SomeWindowsFunctionThatFailsWithCode122();
CString csFilePath = _T("C:\\MyFolder\\");
if (csFilePath != _T("\\"))
{
    DWORD dwError = GetLastError();
}

If nothing calls SetLastError(0), then its internal value will stay 122.

Hi,

Have a quick question on Boost weak pointers. Hope this is the place to ask. I found the article

Smart Pointers to boost your
code[^]

and on the paragraph "cyclic references" in the code there is the line

<br />
child->myDad = dad;<br />

where does the dad come from? Can't seem to see it defined anywhere in the code.

Thanks for any information.

I think it's just a typo. Should be:

child->myDad = parent;

EDIT: You can download the sources just to be certain Smile | :)

Ha ha, yes I did think it should be parent.

Thanks!

Actually, if it was a typo then why does the diagram underneath refer to "dad" and the dad.reset() ? Surely that can't be a typo as well?

As I said before - you really should download the sources first. The code will probably clear things up Smile | :)

Why not post this message on that article rather than here?

Looking at the article, I think that's a typo - dad should be parent

Hmmm, if it was a typo to put "dad" instead of "parent", then is the diagram showing dad pointing to the CDad struct a mistake as well?

He probably used dad and son or boy throughout, then tried to remove the gender specificness as it could be seen as discriminatory? Smile | :)
