Re: Major New User Problems

Hi Barbara,

The method invoke does not belong to Object, you will need to cast to the
relevant Jawin object ie to DispatchPtr before calling invoke().

DispatchPtr oDbf = (DispatchPtr) app.invoke("OpenDB", "customer.dbf");
oDbf.invoke("close");

My expertise is in the Jawin Type Browser so I hope this is correct, guys?

Josh
