Did you know that the CXTShellTree control's PopulateTree method doesn't work with UNC paths?

The problem is in PathFindNextComponent or XTFuncPathFindNextComponent depending on which version of the library you are using.

Anyway, that method will return an invalid path if a UNC path is passed to it

in the PathFindNextComponent the if statement should be

CString CXTShellTreeBase::PathFindNextComponent(const CString& pszPath)

{

// Find the path delimiter

int nIndex = pszPath.Find(_T('\\'));

//if one wasn't found, or the first char is the \

if (nIndex <= 0)

return _T("");

return pszPath.Mid(nIndex + 1);

}

and XTFuncPathFindNextComponent should be:

_XT_EXT_CLASS LPTSTR AFXAPI XTFuncPathFindNextComponent(LPTSTR pszPath)

{

// We will return static memory

static TCHAR tNextComponent[MAX_PATH + 1];

// Make sure we were given a valid path

if ( pszPath == NULL || _tcslen( pszPath ) == 0 ) {

return NULL;

}

// Find the path delimiter

TCHAR *cp = _tcschr( pszPath, _T('\\') );

//if one wasn't found, or the first char is the \

if ( cp == NULL || cp == pszPath) {

// If we didn't find it, return an empty string

tNextComponent[0] = 0;

return tNextComponent;

}

// OK, we have the delimiter. Copy the rest of

// the path to our internal buffer and return it

STRCPY_S( tNextComponent, MAX_PATH , cp + 1 );

return tNextComponent;

}
