Title:
Simple Web App: COM or COM+/MTS
Dear Those-With-More-Experience-Using-COM-on-the-Web,
We have a single server on the Web and want to give users the ability to query a parts table (and do a small amount of data entry). A subset of VFP data we want to make public will be copied to the Web server daily. We're planning to use:
- ASP
- Windows 2000 Server
- VFP7
The VFP7 component, called by ASP, will return a string of html formatted
data based on the parameters submitted by the user.
Given this simple scenario and assuming concurrent users, performance, and
versioning should be considered:
Is COM+/MTS relevant since this is on a single server? Or do I
simply build a server application and install it on the Web server?
At the moment I'm planning to:
- Not use COM+/MTS
- Build a multi-threaded dll
- Initially use InstallShield to install the dll, tlb, and vbr in a [ProgramFiles] folder
- Use Regsvr32 to register it.
To update the server with fixes/enhancements:
- IIS: stop the website
- Unregister the dll
- Copy over the new dll, tlb, and vbr.
- Register the dll
- IIS: start the website
Many thanks for your sanity check.
