SqlServer 2000 sp_OAMethod (wodCrypt)

well, the error is this:

0x80042725 ODSOLE Extended Procedure
without anykind of description

the line of code is this:

EXEC @hr =sp_OAMethod @Crypt, Encrypt , @DecBlob, @EncBlob out

the problem seems to be with the Encrypt method. It seems to be a kind of parameters problems...but i don t know. May be, because, like in C# and Delphi examples, where the memblog is CAST to BLOB until pass it as parameters...but i don t know how to do that with SQLSERVER 2000.

could you help me?...

hI, i was trying to use wodcrypt from inside SqlServer 2000, with sp_OAxxx storeprocedures, but i couldn't. Can anybody helpme? Thats the code in transact sqlserver 2000, and i allways get error.
