Interesting little library, I always wondered about the particular calendar conversion it is advertised to provide.

In looking at this example you provided, to wit:

   k = New .KaluachS

Now this is totally guessing, but I cannot help wondering if KALUACHCOMLib isn't the name of the library, and KaluachS the class, wouldn't it shouldn't be more along the lines of

   k = NEWOBJECT("KaluachS", "KALUACHCOMLib.DLL") 

Of course it would be the main library that would be registered, which is KALUACHCOMLib?

Really hard to guess not having the library in hand, but if you can do it in VB and it doesn't require a callback procedure, you should be able to do it in VFP. Just requires the beating of one's head against the monitor a while...

Just my two centavos ...
