Bug #28161 Fatal error when setting the value of COM object's Attribute property array
Submitted: 2004-04-26 18:00 UTC Modified: 2004-04-29 05:59 UTC
From: spymail at 21cn dot com Assigned:
Status: Closed Package: COM related
PHP Version: 5.0.0RC2 OS: Windows 2000 AS
Private report: No CVE-ID: None
 [2004-04-26 18:00 UTC] spymail at 21cn dot com

The COM runs well in ASP:


'The Attribute property specifies and retrieves name-value pairs.
'Header.Attribute(bstrName) = String
'String = Header.Attribute(bstrName)
'Parameters: bstrName [in] ,String containing the attribute name. 
'Attribute names are case-sensitive, and both the name and value must be specified in a valid 'XML format. If you duplicate an existing attribute, the earlier attribute is updated.

Dim rid
rid = "0"
Set headobj = Server.CreateObject("Wmrmobjs.WMRMHeader")
headObj.Attribute("RID") = rid 


But when I convert it to PHP,there's a fatal error.

Reproduce code:
$headObj = new COM("Wmrmobjs.WMRMHeader");
$headObj->Attribute["RID"] = $rid;

Expected result:
The Attribute should be set.

Actual result:
There's a Error:

Fatal error: Uncaught exception 'com_exception' with message 'Error Invalid
number of arguments' in D:\server\abc.php:3 Stack trace: #0 {main} thrown in D:\server\abc.php on line 3

Did you try RC2 ?

Can you please paste the IDL for the COM object here,
as I don't have that COM object to test against.

Oh yes, I tried RC2 today, same output.

and here is the IDL:

[id(0x000007), propget, helpstring ("property Attribute")]
HRESULT Attribute([in] BSTR bstrName, [out, retval] BSTR* pVal);
[id(0x000007), propput, helpstring ("property Attribute")]
HRESULT Attribute([in] BSTR bstrName, [in] BSTR pVal);

Please try using this CVS snapshot:
For Windows:

I've just committed a fix for this; please try the next snapshot dated after this comment and let me know how you get on.

Well done.

It works pretty well in the latest CVS win32 bulid (Apr 29 2004 04:12:53).
