[PHP-DEV] Bug #12718: com_invoke always seems to return false

[n . morse]

From: [EMAIL PROTECTED]
Operating system: Win 2k
PHP version:  4.0.6
PHP Bug Type: COM related
Bug description:  com_invoke always seems to return false

I created a simple COM objecj in Vis C++.  It has a method hello on it
that does nothing except return S_OK, and a property bar that returns a
string.

I can use com_load to create the object and I can get the property string
back out (com_propget), but if I call hello then it returns FALSE.

$svr = com_load( SIMPLECOMASP.NKMSimpleObj );
$foo = com_invoke( $svr, hello );

if ( $foo )
  echo $foo;
else
  echo No;

I created another method taking a BSTR input and a BSTR* output and that
always returns false with the output being empty.  I tried the calls from
VB as well, and they seem to work OK, so the COM oject looks functional. If
I run the COM exe from the debugger, I can trace through the functions - so
they *are* being called, just a bogus return code from somewhere.

Just to add to this: If I make the return value a retval in the IDL then I can use 
com_invoke and it works (for the same reason that a propget works). It just doesn't 
seem to like normal HRESULT return
