V4MD cursor xtra "Wrong number of parameters" error

[Andrew Sinning]

What do you mean by "Replace"?  Is there a newer file that I should be
using?

It works with the first 3 parameters, so that means the xtra is
installed, right?

Why it doesn't work with 4, 5 or 6 parameters is the mystery.

There's only 1 example in the documentation which uses more than the
first 3 parameters:

	set gCursor = new ( Xtra "VCursor", GetRef(gMyDataBase), SQLstring,
kClient, kReadOnly, kForwardOnly )

This is exactly what I am using, only the variable names are a bit
different:

such as

  -- inLocation:
  kClient =1
  kServer =2
  -- inLockType:
  kNoLock =1
  kReadOnly =2
  kReadWrite = 3
  -- inDirection:
  kForwardOnly = 1
  kRandom = 2

  sql = "SELECT id, idName FROM indices WHERE idName = 'qId'"

  -- note "db" is an object, and db.dbConn is the "VDataBase" xtra with
an open connection to my db.

  -- just 3 params
  theCursor = new(xtra "VCursor", db.dbConn.GetRef(), sql)
  -- WORKS !!!

  -- all 6 params
  theCursor = new(xtra "VCursor", db.dbConn.GetRef(), sql, kClient,
kReadWrite, kForwardOnly)
  -- Nope! {Script Error "Wrong number of parameters"}

  -- 4 params
  theCursor = new(xtra "VCursor", db.dbConn.GetRef(), sql, kClient)
  -- Nope! {Script Error "Wrong number of parameters"}

  -- 5 params
  theCursor = new(xtra "VCursor", db.dbConn.GetRef(), sql, kClient,
kReadWrite)
  -- Nope! {Script Error "Wrong number of parameters"}

Andrew,

May be you have not replace V4MD.Xtra in plugin folder???

If you look into our examples, you will see many places where present
these
3 parameters.

Please check if our examples work for you
