Board index » delphi » DataSetProvider is not visible with Shared Connection

I am using the Shared Connection Example from Dan Miser with Delphi 5( i.e
Main RemoteDatamode with ChildRemoteDatamodule. Everything works fine I can
access and call methods on the main RemoteDatamodule and the Child module. I
cannot see the DataSetProviders on the CliendDataset Provider List. I can
access the ChildRemoteDatmodule and call its methods using a
sharedconnection. I can also access the datasetproviders using a regular
Dcomm or socketconnection. Everything in my code seems to mirror the Dan's
example.
What step am I missing? I'd very much appreciate any help you can give
me on this.
Thanks
Stephen
 

Are you using a ConnectionBroker? The providers should be listed in the
ProviderName drop-down once you hook up the SharedConnection to a
ConnectionBroker and then connect the ConnectionBroker to the ClientDataset.

Dan,
I 'm afraid I am on Delphi 5 so no ConnectionBroker component. I can run the
Downloaded Application from the Distribucon Site no problem and the
Clientdataset can "see" all the Providers, I just can not get it to work in my
own application. All the configuration of the remotedatamodules seems
correct and all other aspects seem to run fine...

Ok, are you setting the RemoteServer property of the ClientDataset to the
SharedConnection?

I rebuilt the application from scratch and everything is working fine now. I
don't know what I did differently but I may have done so much trial an error
work with the type library that some Interface value was messed up.
Thanks Dan for answering so quickly

Glad you got it working.
Not sure if you're using Interbase as the back-end database, but Craig's
article on multi-tier stuff is an excellent reference for what you're trying
to do.

The DSP needs to have Exported := True;
