    <p>I wanted to implement python com server using win32com extensions. Then consume the server from within the .NET. I used the following example to implement the com server and it runs without a problem but when I try to consume it using C# I got FileNotFoundException with the following message "Retrieving the COM class factory for component with CLSID {676E38A6-7FA7-4BFF-9179-AE959734DEBB} failed due to the following error: 8007007e." . I posted the C# code as well.I wonder if I'm missing something I would appreciate any help.</p> <p>Thanks, Sarah </p> <pre><code>#PythonCOMServer.py import pythoncom class PythonUtilities: _public_methods_ = [ 'SplitString' ] _reg_progid_ = "PythonDemos.Utilities" # NEVER copy the following ID # Use"print pythoncom.CreateGuid()" to make a new one. _reg_clsid_ = pythoncom.CreateGuid() print _reg_clsid_ def SplitString(self, val, item=None): import string if item != None: item = str(item) return string.split(str(val), item) # Add code so that when this script is run by # Python.exe,.it self-registers. if __name__=='__main__': print 'Registering Com Server' import win32com.server.register win32com.server.register.UseCommandLine(PythonUtilities) // the C# code using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { Type pythonServer; object pythonObject; pythonServer = Type.GetTypeFromProgID("PythonDemos.Utilities"); pythonObject = Activator.CreateInstance(pythonServer); } } } </code></pre>

    1. CONote warning in the python code, not to use a new GUID on every call. Create a GUID only once.

    2. COThe code you posted is for registering a COM server; do you also have implemented (and running) the actual server?

    3. COI thought registering the server means it is running. Can you give me more guides. thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
