Re: Access Denied error on calling CFile::GetStatus() function
Hmmm, I didn't know your problem was with an exception. I also did the same
sort of thing a year or so ago with this function for the same issue. I
just call this instead of the CFile version. Sorry, I didn't know you had
the same problem and I didn't know they "didn't" fix it for 2005 since I
don't use that function in CFile any longer. I'm surprised though. We've
been griping about it failing on invalid dates since around version 5 :o)
and the fix is pretty easy.

It was a typo that I passed & of FileStatus Object. In the actualy
code I've written it properly.
The last error was set to 0.
I shalll try with the code you specified. But the CFile::GetStatus
working properly with the directories in of local drive but not
working fine with the network file paths.
Ah joy. You have to replace CFile::GetStatus. Often, network/cd
drives/etc have bad dates. When GetStatus reads the info, the underlaying
CTime throws. VC8 does NOT fix this. I've seen cases where
CTime::IsValidFILETIME returns true, but CTime(filetime) throws.
What I did was to copy the GetStatus code from the MFC source. Then
around each status time field do the following (this is based on the VC8
source):
if (CTime::IsValidFILETIME(findFileData.ftCreationTime))
{
try
{
rStatus.m_ctime = CTime(findFileData.ftCreationTime);
}
catch (COleException* pe)
{
pe->Delete();
rStatus.m_ctime = CTime();
}
}
else
{
rStatus.m_ctime = CTime();
}
