>parameter registro is the rec number i'need obtain datas to that number. than'u how i make that.

Oh you mean parameter. Then depending on your backend select command should look like:

"select * from recordfile where myPrimaryKeyField = ?"

"select * from recordfile where myPrimaryKeyField = @id"

It can't be record number however but primarty key (most backends do not have a concept of recno()).
