From: Geoff Schaller on 2 Apr 2010 19:50 Woerdie, Let's try and do this. The following code works for me: METHOD GenereerArtDbf2(cOutput, cSortGang, cFile) CLASS FacturenBrowse LOCAL nCurrentRecno AS WORD LOCAL oWin AS PrintProgress LOCAL n, y AS WORD LOCAL aDBStructure AS ARRAY LOCAL oOutput AS Facturen LOCAL oFacturen AS Facturen oFacturen:=Facturen{} IF !oFacturen:CreateOutputDBF() // report an error creating the DBF and take evasive action ENDIF oFacturen:Close() // but you don't have to if you need to use the data... oOutput:=Facturen{"OUTPUT"} // Open the DBF // use oOutput oOutput:Close() RETURN NIL METHOD CreateOutputDBF() CLASS Facturen LOCAL aStruct AS ARRAY LOCAL lReturn AS LOGIC aStruct := SELF:DBFStructure // create a new DBF with the same structure but different name lReturn := DBCREATE("OUTPUT",aStruct,"BDBFCDX",TRUE,__UniqueAlias("OUTPUT")) DBCLOSEAREA() // flush to disk and close RETURN lReturn Now let's get one thing clear first: you have a DBServer class generated with the DBServer editor... yes? Good. Because of this, we can use that class for the input and output DBF in our code. We just pass the name of the DBF (NOT NOT PASS .DBF WITH THIS NAME) to the instantiation clause and it will pick up the correct DBF. I have not passed in the working folder path with the name but of course you can do this too. You can also create an output class to use like this: CLASS OutputFacturen INHERIT Facturen Now it will work. Cheers, Geoff

User 2 won't be able to create the file because User 1 is using it (unless it's a single User app!) Use a temp filename for temporary DBFs, delete DBF when finished with. CYA Steve
