[python-win32] issue regarding connectivity between client and com server.

[Madhubala]

Hi ,

 

 

I have an issue regarding connectivity between client and com server.

 

I have a com server implemented in MFC dll having MFC as static library.

The requirement is to write python wrapper to it  .

 

Using ctypes  I wrote a wrapper to MFC dll which exports couple of functions

for com initialization and registration.

 

Following is My python  pseudo code  

-----------------------

Loading the dll

 

Call to  initialization function in the dll

 

Call to rigstration   function in dll   (this sequence is specified by the

dll documentation.  I tried   changing the sequence too )

 

While true  loop   - this is just to keep server running 

 

GUID for com server object is passed as argument  to initialization script

and all the registry entries  seems to be correct when tested with

Microsoft visual studio 6.0  tool  "ole view"  . But when I try to

instantiate through ole view tool or through any other client  -  it  hangs

up forever till I break the server and shows an error that either no inproc

/local server is found . 

 

when I create a 'c' application linking to the same above MFC dll , it is

working fine   to initialize and register and running  a server. All

security initialization is taken care in the dll . So the way my c code is

working , my python code also should work. When I compared the registry

entries of  servers registered with c application and  python application  I

found that  both entries are similar and could not find any faulty entry for

python code .

 

Can anyone explain why this behavior is and  any solution to the above

problem?

 

Thanks,

Madhubala
