I tried using it with wx.lib.iewin.IEHtmlWindow of wxPython 2.5.1.5
There is a problem in this function:
def sendWM_COMMAND(ie, cmdcode, command=win32con.WM_COMMAND):
# Get the 'Shell Embedding' window.
cwnd = ie._obj_
# Get the 'Shell DocObject View'
cwnd = cwnd.GetWindow(win32con.GW_CHILD)
# Get the 'Internet Explorer_Server'
cwnd = cwnd.GetWindow(win32con.GW_CHILD)
cwnd.SendMessage(command, cmdcode, 0)
AttributeError: 'IEHtmlWin' object has no attribute '_obj_'
Which class has this 'SendMessage' method and how to get it from
'IEHtmlWin'?

Subject: [wxPython-users] Cut, Copy and Paste shortcuts are now working in
ActiveXWrapper_IE
Hi,
after spending some hours searching for the solution of the shortcuts, the
answers point into something involving functions like
IOleInPlaceActiveObject::TranslateAccelerator,
PreTranslateMessage, wxApp::ProcessMessage, wxApp::ProcessMessage,
wxWindowMSW::MSWProcessMessage. None of them seem to be easily accessible
using wxPython, win32all or ctypes functions, at least not for me.
Instead I came up with a workaround in the wrong direction that covers at
least the basics which are the delete key, cut, copy, paste and undo. The
method only works for simple pages, not for frames or embedded objects like
Flash.
The WM_COMMAND numbers I got from what Winspector logged
while the respective functions were performed in the
original Internet Explorer.
There was no information to be found on the web to relate
these numbers to well known symbols or commands.
I only tested this with wxPython 2.4.2.4u on W2K and IE 6.0.
To see the results, just put the following code inside
the ActiveXWrapper_IE.py demo.
Good luck,
Michael
