You might already have this working, but even if you do, maybe this will help someone else. I played with this a little while ago and it appears that VFP doesn't create a proper .TLB file when defining your methods in code.

For example:

FUNCTION Method
LPARAMETERS tcValue

* Do something

ENDFUNC

This method takes one parameter, tcValue. However, the TLB created by VFP doesn't show ANY parameters. Because VC++ imports the type library created by VFP, it (incorrectly) finds a method that doesn't have any parameters (which is where your error is coming from).

If you change the code to this instead:

FUNCTION SomeMethod(tcValue)

* Do something

ENDFUNC

The generated TLB is correct and VC++ will stop complaining.

This appears to be the case in both VFP 7 and the public VFP 8 beta.
