Hi all
I followed the steps described in C++Builder Unleashed, in order to
create a simple MIDAS server and client. In brief, the steps I took
were
For the server
S1/ Create new application
S2/ Add a Remote DataModule
S3/ Add a TDatabase, a TQuery and a TTable, set them up (they point to
the employee.db file), then activate them
S4/ Make the SERVER.EXE, then run it: SERVER /RegServer
For the client
C1/ Create new application
C2/ Add a RemoteServer, set the RemoteServer property (selected
through the combo), activate it
C3/ Add a ClientDataSet, connect it to the remote server, connect it
to the remote dataset (I see both query andtable in the combo)
C4/ Try to activate the CDS. I receive the following message

'src->QueryInterface(GetID(), (LPVOID*)(&intf))': No such interface
supported
@D:\DEVTOOLS\BCB4\INCLUDE\VCL\utilcls.h/2014
Yes, No, Cancel

and, off course, I cannot connect.

Hm!?!? Any ideas?

TIA

PS A search on deja return many messages but I cannot see any - "Local
server error" it says :(
