Bug #16323 Updated: php_OLECHAR_to_char() error in IIS

ID: 16323 Updated by: Vladimir.Michl@hlubocky.del.cz Reported By: preston.bannister@cox.net Status: Open Bug Type: COM related Operating System: Windows 2000 Professional PHP Version: 4.1.2 New Comment: I found the same problem with php 4.1.1, if OLE Automation object return empty string. After some testing a have this result: OLE Automation server return Variant with type 0x08 - OLE Str. To php_OLECHAR_to_char() (in conversion.c) as unicode_str arrive probably NULL, because WideCharToMultiByte return 0 and in my simulations WideCharToMultiByte return 0 if unicode_str is NULL. I thing that, if unicode_str is NULL, php_OLECHAR_to_char() must convert it to empty string, without any warning.
