Thanks Patric. I think I found the problem.
When I change Your code in cursor adapter to ADO connection set the error arise. I change ONLY follow:

* Your code
this.DataSourceType = "ODBC"
This.DataSource = sqlstringconnect([driver={Sql server};server=(local);usid=sa;pwd=kan67;database=task;);););)] + ;


*My code
this.DataSourceType = "ADO"

local loConnDataSource
loConnDataSource = createobject('ADODB.Connection')
***<DataSource>
loConnDataSource.ConnectionString = [Provider=SQLOLEDB.1;Password=sa;Persist Security Info=True;User ID=sa;Init] + ;
    [ial Catalog=Task;Data Source=ZOGRAFSKI;]
***</DataSource>
loConnDataSource.Open()
This.DataSource = createobject('ADODB.RecordSet')
This.DataSource.CursorLocation   = 3  && adUseClient
This.DataSource.LockType         = 3  && adLockOptimistic
This.DataSource.ActiveConnection = loConnDataSource

May be this is a BUG?
Thanks for your time
