<h1>Python COM Extensions Readme </h1>
|
||
|
|
|
||
|
|
<p>This is the readme for win32com. Please check out the <a
|
||
|
|
href="html/docindex.html">win32com documentation index</a></p>
|
||
|
|
|
||
|
|
<p>The <a href="test/.">win32com/test directory</a> contains some interesting
|
||
|
|
scripts (and a new <a href="test/readme.txt">readme.txt</a>). Although these
|
||
|
|
are used for testing, they do show a variety of COM techniques.</p>
|
||
|
|
|
||
|
|
<h3>VARIANT objects</h3>
|
||
|
|
<p>win32com.client now has explicit VARIANT objects which can be used in
|
||
|
|
situations where you need more control over the argument types passed when
|
||
|
|
calling COM methods. See the <a href="html/variant.html">documentation on
|
||
|
|
this object</a>
|
||
|
|
|
||
|
|
<a name="currency"><h3>Important Currency changes</h3></a>
|
||
|
|
<p>
|
||
|
|
In all builds prior to 204, a COM currency value was returned as a tuple of
|
||
|
|
integers. Working with 2 integers to represent a currency object was a poor
|
||
|
|
choice, but the alternative was never clear. Now Python ships with the
|
||
|
|
<a href="http://www.python.org/dev/doc/devel/lib/module-decimal.html">decimal</a>
|
||
|
|
module, the alternative has arrived!
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Up until build 212, code could set <code>pythoncom.__future_currency__ = True</code>
|
||
|
|
to force use of the decimal module, with a warning issued otherwise. In
|
||
|
|
builds 213 and later, the decimal module is unconditionally used when
|
||
|
|
pythoncon returns you a currency value.

<h3>Recent Changes</h3>
|
||
|
|
|
||
|
|
<h4>Lots of internal changes on the road to py3k</h4>
|
||
|
|
|
||
|
|
<h4>win32com.axcontrol and win2con.internet</h4>
|
||
|
|
Many more interfaces for hosting AX controls and the interfaces
|
||
|
|
used by Internet Explorer.
|
||
|
|
|
||
|
|
<h4>win32com.shell</h4>
|
||
|
|
The shell interfaces have undergone a number of enhancements and changes.
|
||
|
|
A couple of methods have changed signature between the first build with shell support (200) and later builds.
|
||
|
|
SHGetFileInfo was broken in its result handling, so had to be changed - this
|
||
|
|
is the only function used by the samples that changed, but others not used by the samples also have changed.
|
||
|
|
These shell interfaces are now generally stable.
|
||
|
|
<h4>New win32com.taskscheduler module</h4>
|
||
|
|
Roger Upole has contributed an interface to the Windows task scheduler. This is actually very neat, and it allows
|
||
|
|
Python to edit the task list as shown by Windows Control Panel. Property page suppport may even appear later,
|
||
|
|
now that the win32 library has the new win32rcparser module.
|
||
|
|
<h4>ActiveX Scripting </h4>
|
||
|
|
|
||
|
|
<p>Python only supports "trusted" execution hosts - thus, it will no longer work
|
||
|
|
as an engine inside IE (Python itself no longer has a restricted execution environment).
|
||
|
|
Python continues to work fine as an Active Scripting Engine in all other
|
||
|
|
applications, including Windows Scripting Host, and ASP.
|
||
|
|
|
||
|
|
<p>There is also support for Python as an ActiveX Scripting Host.</p>
|
||
|
|
|
||
|
|
<p>Active Debugging seems to be fully functional.</p>
|
||
|
|
|
||
|
|
<h4>Older stuff</h4>
|
||
|
|
<ul>
|
||
|
|
</li>
|
||
|
|
<li>Unexpected exceptions in Python COM objects will generally now dump
|
||
|
|
the exception and traceback to stdout. This is useful for debugging
|
||
|
|
and testing - it means that in some cases there will be no need to register
|
||
|
|
an object with <span style="font-style: italic;">--debug</span> to see these
|
||
|
|
tracebacks. Note that COM objects used by server processes (such as
|
||
|
|
ASP) generally have no valid stdout, so will still need to use <span
|
||
|
|
style="font-style: italic;">--debug</span> as usual.<br>
|
||
|
|
</li>
|
||
|
|
<li>universal gateway support has been improved - we can now work as an
|
||
|
|
Outlook Addin<br>
|
||
|
|
