Add a special case for RETVAL_VARIANT when a variant is of type VT_DISPATCH but has a NULL dispatch pointer.
This kind of variant is returned by the WindowsInstaller automation interface.
It is expected that this function will be transient, waiting for engine-level and then rpc-level support to be implemented so that this can be integrated more completely.
I'm committing this now so that others can help develop the msi installer scripts that require this feature.
windows sockets. The winsock implementation will only work with sockets;
our implementation works with sockets and file descriptors.
By association, stream_select() will now operate correctly with files, pipes and sockets.
This change required linking against the winsock2 library. In terms of
compatibility, only older versions of windows 95 do not have winsock2
installed by default. It is available as a redistributable file, and is most likely installed by any OS patches (eg: Internet Explorer) applied by the user.
Also, add a win32 compatible pipe test when opening a stream from a pipe. This test will only work on NT, win2k and XP platforms. Without this test, interleaved fread() and select() calls would cause the read buffer to be clobbered. I will be working on a fix for this issue for win9x.
The main expected use is like this, for figuring out what methods
are allowed for a COM object:
$ie = new COM("InternetExplorer.Application");
// Prints class definition for IE object
com_print_typeinfo($ie, "InternetExplorer.Application", false);
// Prints class definition for default IE event handler
com_print_typeinfo($ie, "InternetExplorer.Application", true);
rather than longs.
- Make the IDispatch implementation a bit more generic (and
fix my mess of pointers).
- Add new com_message_pump() function that acts like an interruptible
usleep() that processes COM calls/events.
- Add new com_print_typeinfo() function for "decompiling" the typeinfo
for an interface into PHP script. This is useful for generating a
skeleton for use as an event sink.
- Add new com_event_sink() function for sinking events from COM
objects. Usage is like this:
<?php
class IEEventSinker {
var $terminated = false;
function ProgressChange($progress, $progressmax) {
echo "Download progress: $progress / $progressmax\n";
}
function DocumentComplete(&$dom, $url) {
echo "Document $url complete\n";
}
function OnQuit() {
echo "Quit!\n";
$this->terminated = true;
}
}
$ie = new COM("InternetExplorer.Application");
$sink =& new IEEventSinker();
com_event_sink($ie, $sink, "DWebBrowserEvents2");
$ie->Visible = true;
$ie->Navigate("http://www.php.net");
while(!$sink->terminated) {
com_message_pump(4000);
}
$ie = null;
?>
