Moving from COM to DCOM

[longyp]

I am quite pleased with myself. I have an ActiveX EXE which runs SQL queries asynchronously and notifies my clients when the query has finished. Not bad eh ?..well for me anyway

I am now thinking about moving this EXE to a dedicated high powered Server.

How do I configure the clients to reference the EXE on another machine.

Is there coding required in the EXE or is it all done for me my DCOM config. program within Windows

If the High-Power Server capable of supporting VB DLL's ? I.e it's not a Linux/Unix/somsuch machine then to move to DCOM is simple.

All you need to do in install/deploy your DLL to the new server (not forgetting to configure your database connection of your server etc !!). Open the Client VBP and make a Networked Path reference to the DLL on the new server & re-deploy the client.

Of course, things to consider when deploying the DLL are any dependencies the DLL may require, connections to Databases etc etc, the load the DLL will have to take... It really depends upon how tight you coded your DLL and what it's for. But assuming your Error Handling etc follows COM rules etc then there should in theory be No problem.

Thanks for the reply. It had been v. quiet up until then,,I thought I had asked a question dealing with Black Magic.

I will give this a try. This really sounds too simple. I hope it works.

Thanks, I will let you know.

Dear

if u want to deploy the DLL then u can od this with the MTS
and if u hv use EXE then u can do this by DCOM support
obviosly for dll also and the instance will depend on the instancing property of the class what u hv set
multiuse,singleuse etc
