Ha, I did just that and the DLL then refused to even instantiate.

function error
lparameters nError,cMethod, nLine
this.lError = .t.
this.cErrorMessage = ""
this.cErrorMessage = "<br>Error No: " + str(nError) + ": " + ;
		"<br>Method: " + cMethod + ;
		"<br>Line No: " + str(nLine) + ;
		"<br>Message: " + message() + message(1) + "<HR>"				
comreturnerror(this.cErrorMessage,_vfp.servername)
endfunc

Took out that 1 line and it works OK.

>>Thanks Craig. I had read that before and I hate to say its still pretty greek to me. The help fails to provide an example that would be really helpful. AS I read it, we would still need something to trigger the COMRETURNERROR() call. What would that be? and how would we access the returned value from an ASP page?
