Edit report at https://bugs.php.net/bug.php?id=50305&edit=1 ID: 50305 Updated by: cmb@php.net Reported by: noon at ms8 dot url dot com dot tw Summary: DOTNET Warning Status: Assigned -Type: Bug +Type: Documentation Problem Package: COM related Operating System: Windows Vista PHP Version: 5.3.1 Assigned To: cmb Block user comment: N Private report: N New Comment: Doesn't make sense to wait for a magic fix – changing to doc issue. Previous Comments: ------------------------------------------------------------------------ [2020-02-07 10:48:13] cmb@php.net That COM object is supposed to implement IDispatch, but apparently it does not; converting it to a PHP Variant (like in the attached patch accept-LPUNKNOWN) would not solve the problem (while it makes the OP's test script work, it still leaves a practically unusable Controls object, because it only postpones the problem). ------------------------------------------------------------------------ [2013-10-18 02:41:42] eric at pby dot com I'm not proficient enough in C to even compile PHP. Until this bug is fixed in a stable release, is it possible to define a PHP class that mirrors the COM class and cast the object into that class so that I can access its functions and properties? ------------------------------------------------------------------------ [2013-02-20 14:39:18] user at kkdf2 dot sakura dot ne dot jp I've posted a patch. I'm not sure whether it works well or not. ------------------------------------------------------------------------ [2011-01-14 08:40:11] kalle@php.net This means that the variant conversion (as the error says) failed, 0xD is the variant type value of the object being converted. 0xD evaluates to 13 which is VT_UNKNOWN, an object that implements the IUnknown interface. I however doubt theres anyone who will look at fixing this anytime soon as COM/dotnet needs an active maintainer ------------------------------------------------------------------------ [2011-01-13 12:51:02] t33th4n at gmail dot com Description: ------------ Error is valid. Trying to create a dialog with .NET, but basic functions are failing to proceed.
