I would rather expect that they use a VT_UI4, or more likely a VT_PTR. And actually, why would that API not accept a VT_DISPATCH, and call a certain method on that? The latter is already supported by the COM extension, through `new variant($php_obj);`. Is it possible that the VT_I4 is supposed to be a DISPID? Is that documentation still publicly available? ------------------------------------------------------------------------ [2009-09-08 08:59:42] RQuadling at GMail dot com Description: ------------ Hi. I think I'm pretty much on my own here, but here goes. I'm evaluating a COM tool to allow me to OCR documents. The COM object requires the registration of a callback to allow the object to send results as it finds them (events in their terminology) back to a handler for processing (say logging in a DB, etc.). According to their documentation, in C and VB, the registration is a trivial process of simply supplying the address of the function as the handler for the callback. Obviously, this won't work in PHP as a PHP function isn't accessible like a compiled function from outside of PHP. The "value" to be supplied is of type VT_I4. This is essentially just the address of the function (as I see things). So, I think that a proxy is needed. Something to act in the middle of the PHP script and the callback invocation by the COM object. Any ideas? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=49497&edit=1
