Hello,

I am using GetName() function to load elements inside a list. However when I am allowing my populatelist function to run on Temporary Internet Files it throws an exception details:

Path: C:\Doc & Settings\..My profile\Local Settings\Temporary Internet Files\

Debug Assertion Failed:
File:.\tcscpy_s.inl
Line: 30

Expression:(L"Buffer is too small" && 0)

Anyone any idea whats going on?

One observation is that this temporary internet folder has a file name that has file name excluding extension definately greater than 260.

Thanks,

Sachin Modak.

Hi,

Here is what you asked for. It seems that there is a buffer overflow in STRCPY_S()...

BOOL CXTShellPidl::GetName(LPSHELLFOLDER lpsf, LPITEMIDLIST lpi, DWORD dwFlags, TCHAR* lpFriendlyName)

{

...

if (lpsf->GetDisplayNameOf(lpi, dwFlags, &str) == NOERROR)

{

switch (str.uType)

{

case STRRET_WSTR:

#if defined(_UNICODE)

STRCPY_S(lpFriendlyName, MAX_PATH, str.pOleStr);

#else

::WideCharToMultiByte(CP_ACP, 0, str.pOleStr, -1, lpFriendlyName,

MAX_PATH, NULL, NULL);

...

}

hope this helps.

Sachin Modak.

Hello,

Hmm.

right, lpFriendlyName has only 255 symbols (MAX_PATH) we will fix it to replace LPCTSTR lpFriendlyName to CString&

Thank you for let us know.
