pythonCOM with Flash

[Bradley Schatz]

Hi Mark,

thanks for the pointers previously.

I have had a further play using the demos you mention, from within
pythonwin.

Here are some notes for things that I dont quite understand..

Makpy finds two typelibraries for Shockwave Flash 1.0 If I look at them
using the MS COM Object viewer, I see that one of them points to an .ocx and
the other points to a .oca

I have modified the webbrowser.py example to use flash - the source is
below.

When I use the IID that points to the ocx (begins with D27) I get the
following trace from within pythonwin:

  File
"C:\Python23\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py",
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\projects\flash\flash2.py", line 13, in ?
    FlashModule =
gencache.EnsureModule("{D27CDB6E-AE6D-11CF-96B8-444553540000}", 0, 1, 0)
  File "C:\Python23\lib\site-packages\win32com\client\gencache.py", line
347, in EnsureModule
    tlbAttr = pythoncom.LoadRegTypeLib(typelibCLSID, major, minor,
lcid).GetLibAttr()
com_error: (-2147319779, 'Library not registered.', None, None)

When I use the IID that points to the .oca I get the following.

  File
"C:\Python23\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py",
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\projects\flash\flash2.py", line 60, in ?
    Demo()
  File "C:\projects\flash\flash2.py", line 57, in Demo
    f.Create("Flash Player")
  File "C:\projects\flash\flash2.py", line 42, in Create
    self.ocx.CreateControl("Flash Player", win32con.WS_VISIBLE |
win32con.WS_CHILD, rect, self, 1000)
  File "C:\Python23\lib\site-packages\Pythonwin\pywin\mfc\activex.py", line
23, in CreateControl
    self.__dict__["_obj_"] = win32ui.CreateControl(clsid, windowTitle,
style, rect, parent, id, lic_string)
win32ui: CreateControl failed

Any suggestions on what I may be misunderstanding here would be greatly
appreciated.
