Description:
------------
The .NET sample from the manual (stack, Pop(), Push()) works fine with the new patch, however I encounter problems instanciating .NET objects that are _not_ in mscorlib. I don't think there is an error in my code. 

Reproduce code:
---------------
<?php
  $dotnetxsl = new DOTNET("System.Xml", "System.Xml.Xsl.XslTransform");
?>

Expected result:
----------------
no output

Actual result:
--------------
Fatal error: Uncaught exception 'com_exception' with message 'Failed to instantiate .Net object' in e:\Inetpub\wwwroot\php\dotnet1.php:2 Stack trace: #0 {main} thrown in e:\Inetpub\wwwroot\php\dotnet1.php on line 2

Hey Christian,

You probably need to fully qualify the assembly name to get it working.

Here's a non-working example; the assembly is loaded but object unwrapping doesn't give us an IDispatch'able handle, so instantiation fails.

Don't ask me how you determine the version and key tokens; I pulled these out of a decompiled .tlb file :-/

$f = new DOTNET('System.Windows.Forms,Version=1.0.5000.0,Culture=neutral,PublicKeyToken=b77a5c561934e089', 'System.Windows.Forms.Form');

PS: the next HEAD snapshot will contain better startup and error reporting for these things; possibly fixing that other  .net bug you reported a little while back.

Description:

As far as I can tell this bug is still present in 5.2.6. Using a fully qualified assembly name reproduces a different error, so it might be a step closer to working. 


Reproduce code:
---------------
$object = new DOTNET( 'System,Version=2.0.0.0,Culture=neutral,PublicKeyToken=B77A5C561934E089', 'System.Diagnostics.Process' );


Expected result:
----------------
- no output --


Actual result:
---------------
PHP Fatal error:  Uncaught exception 'com_exception' with message 'Failed to instantiate .Net object [Unwrapped, QI for IDispatch] [0x80004002] No such interface supported
'

This bug is still present in PHP 5.3.8.

Here is the code I tried to use:

$sp = new DOTNET('System, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089', 'System.IO.Ports.SerialPort');

The error message:

Fatal error: Uncaught exception 'com_exception' with message 'Failed to 
instantiate .Net object [Unwrapped, QI for IDispatch] [0x80004002] No such 
interface supported '

Reopening per the last two comments, although I suspect this is firmly in the 
"patches welcome" category.

Strange... the first works, the second gives that exception:

$fm = new DOTNET('System.Windows.Forms, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089', 'System.Windows.Forms.Form');

$sp = new DOTNET('System, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089', 'System.IO.Ports.SerialPort');

Both are with fully qualifie assembly name... 
Is there any way to activate more detailed debugging informations to see what is 
happening in background?

I think the problem here is that you can only instantiate .NET classes where they're decorated with the ComVisible(true) attribute.

For example in the documentation sample code here:

http://www.php.net/manual/en/class.dotnet.php

The System.Collections.Stack class is decorated with this attribute:

http://msdn.microsoft.com/en-us/library/system.collections.stack.aspx

As is the System.Windows.Forms.Form class example earlier in this bug report.

However if one tries to instantiate a .NET class without this attribute such as System.Xml.XmlDocument:

http://msdn.microsoft.com/en-us/library/system.xml.xmldocument

Then an exception is thrown:

$xml = new DOTNET('System.Xml, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089', 'System.Xml.XmlDocument');

Produces:

PHP Fatal error:  Uncaught exception 'com_exception' with message 'Failed to instantiate .Net object [Unwrapped, QI for IDispatch] [0x80004002] No such interface supported

These are my findings from working with .NET 2.0. There seems to be additional problems with instantiating .NET 4 classes because of changes in the way the GAC is used (or not).
