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

minkowski7-May-09 23:17

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 | :)

I'll try and email the author (if thats possible) as it is a good article and I want to get my head round it.

You should go deeper with the debugger.

I already went deeper in the Debugger, i still could not fix the problem.

Go deeper. Can't you see what assertion is failing?

in the Test_Doc.cpp file(SDI_Appliction), i use the following code:

void CTest_Doc::OnInputFont()
{
CTestFontDialog sfdlg; // CTestFontDialog is derived from CFontDialog
tfdlg.OnInputFontDialog();
}

and this code is in the OnInputFontDialog()
{
LOGFONT lf;
CFont *pFont = GetFont(); // Fehler
pFont->GetLogFont(&lf);
.........
}
the OnInputFontDialog() is in TestFontDialog.cpp this class is derived from CFontDialog.

How can i see what fail the assertion?
m_hWnd = 0x00000000
maybe this is why?

Hamid_RT8-May-09 0:43

Usually GetFont has retuns valid but you dont have any window(m_hWnd=0x0000) so it cant return anything.
