[DUG] COM issue

[Jolyon Smith]

First up, if both are running as separate processes then nothing is in the
"same space" as such.

It's been a long time since I did any detailed COM work so I'm a bit rusty,
but I think the key to this will be the threading and instancing model your
COM server is employing in the A process and re-entrancy issues in the A
process.

Hi

I have app A that runs (using create process) app B.  App B at one point 
tries to use COM to access app A.  This freezes.  When app B is run 
manually it works fine.  I assume this has something to do with B 
running in the same 'space' as A.  I have tried

CreateProcess(Nil, pChar(appName + ' AUTORUN'), nil, nil, false, 
DETACHED_PROCESS + NORMAL_PRIORITY_CLASS, nil, nil, startinfo, 
proc_info) <> False)

But to no avail.

Any suggestions?

Thanks
Rob
