[python-win32] Python-win32 Digest, Vol 53, Issue 6

[Huang Guan]

Dear Sirs,

Thanks for the detail comments from Tim Roberts,Roger and Michel Claveau,
question 1, 2, 4 have been finished.

I am doing a anti pornography and violence software, which face to the
youngers.

Convenience to distribute the software and restrictc some mischievous
youngsters to shut down this program, that's why I need to settel the
problem 1.

Regarding to the problem 2, I found it and major in reserching technic, not
mean others.
Now we could reolve the problem 1 and 2, it's unneccessary to discut it any
more.

Thanks for the Michel Claveau's suggestion help me settled problem 4.

question 1, 2, 4 have been finished.


I need your help on question 3 still:

import pythoncom
from win32com.server import util
f=open('somepage.html','r')
fs=util.FileStream(f)
istream=util.wrap(fs, pythoncom.IID_IStream )
p=ie.Document._oleobj_.QueryInterface (pythoncom.IID_IPersistStreamInit)
p.Load(istream)

p.Load(istream)tested and excuted successful, thank you.

f=open('somepage.html','w+')
fs=util.FileStream (f)
istream=util.wrap(fs, pythoncom.IID_IStream)
p=ie.Document._oleobj_.QueryInterface(pythoncom.IID_IPersistStreamInit)
p.Save(istream,True)

Why p.Save(istream,True) can excuted, but error massage as below:
pythoncom error: Unexpected gateway error
<type 'exceptions.TypeError'>: an integer is required
check somepage.html file current dir,is exists,size:5kb,
but the file is not complete html source.
How to resolve the p.Save() problem?

v_StringIO=StringIO.StringIO()
v_f_object=open(' somepage.html','r')
v_StringIO.write(v_f_object.read())
v_f_object.close()
fs=util.FileStream(StringIO)
istream=util.wrap(fs, pythoncom.IID_IStream)
p=ie.Document._oleobj_.QueryInterface (pythoncom.IID_IPersistStreamInit)
p.Load(istream)

p.Load(istream) excuted successfully, but do not get values from v_StringIO,
why?


Thanks & best regards!
