External COM objects

I can currently access a DLL i have locally on my machine with the CreateObject command below.

o = CreateObject("Application.Class")

This will only work if that DLL is registered on that local machine.
How would i access a DLL off of a server or centralized machine?
This would allow me to avoid installing software on hundreds of machines, very beneficial!

Check CreateObjectEX in help. I never make it works but you can be luckier than me

it looks like that just might work. however, i too have not had much luck with it.

Sorry, but CREATEOBJECTEX() won't work with a DLL.

Josh, can you re-build your class as an EXE? That way, you will be able to instantiate it with CREATEOBJECTEX(). If you can't work out how to do that, come back and I'll try to talk you through it.

Well i am getting closer. I was getting no where with the dll, so i rebuilt my class as an exe as MikeLewis suggested. I could successfuly run the exe using CREATEOBJECTEX() in my code from my local machine.

Moved the exe to the server and registered it. Now trying to run my code from my local machine using the exe on the server, getting 'The system cannot find the path specified' error.

Josh,

I assume the EXE is registered on both the server and the client machine?

Do you know where the error message is being generated? Is it a VFP error from within your EXE, or an OS-level error, or what? (It doesn't sound like a VFP error.)

Josh,

Another thought: as well as registering the EXE on the server, you will also need to install the VFP runtime files on the server.

It is a FoxPro program error, stating exactly:
OLE error code 0x80070003: The system cannot find the path specified.

As far as the exe itself, registering it on every pc in the company would defeat the purpose of running it off of the server. I can run the exe locally from my machine, and locally from the server, because it is registered on both. However, i can not run it on the server from my machine using CREATEOBJECTEX(), i get the error above.

Everything needed to run the program is on the server and functional. I just need to be able to access it remotely.

Thanks,
Josh
