Help, I am a begginer of pythonwin32

[jnut]

I made a python class. And test it ok.
And build it to a com.
In asp file (com.asp):
<%
        set dObj = CreateObject("ImageServer.Application")
        dObj.resizeTo"C:\Inetpub\wwwroot\a.jpg","C:\Inetpub\wwwroot\-
        2.jpg",100
        set dObj = nothing
%>

It's alway turn out a error:
        Python COM Server Internal Error (0x80004005)
        /com.asp, line: 3

1. How can I know the error line and what error that is?
2. Did you have a way to reload your python com? I mean , After I have
   some changes done, re-register the python file, I can not see any
   effect when I refresh the ie. . Maybe a few minutes later , or
   restart my windows, it worked.
I can not find any document of that. And there is no any help or
documation of pythonwin32 or pythoncom in china.

Thank you all.
