You cannot pass parameters to a COM DLL Init. You can add another method, say SetRatePath, to do the same.

>I have a DLL that had a procedure that accepted an XML string. My users now want to send a string containing a path before calling the XML proc. I want to have an INIT procedure in my class and allow it to accept a string, then set that to a variable that the procedure accepting the XML can use.

>My class is defined as CALC_FI and it's in CALC_FI.DLL The main procedure is Calc_pmt. I have added an Init procedure that should accept the path string, then place it into a protected variable called cRatePath, to be used by Calc_pmt when needed.

>My problem is that I am unable to use CREATEOBJECT anymore. Without the Init procedure, I could previously use CREATEOBJECT("calc_fi.calc_fi") and then later call the calc_pmt procedure in the class. With the Init procedure accepting a parameter, the CREATEOBJECT("calc_fi.calc_fi","C:\") fails. If I use NEWOBJECT("calc_fi","calc_fi.prg",NULL,"C:\"), everything works fine.
