Bug #12718 Updated: com_invoke always seems to return false

ID: 12718 User updated by: n.morse@hyperknowledge.com Reported By: n.morse@hyperknowledge.com Status: Open Bug Type: COM related Operating System: Win 2k PHP Version: 4.0.6 New Comment: 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 Previous Comments: ------------------------------------------------------------------------ [2001-08-13 11:35:58] n.morse@hyperknowledge.com 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. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12718&edit=1
