Selection Formula COM viwers

[gonsales]

With ActiveX I use "sf" command to set the selection formula to my reports, but I don't know how to do it with COM Viewers....
I've found how to pass parameters
-
Set reportInterface = reportObject.PluginInterface("&quot
Set NewValue =reportInterface.ReportParameters.Item(1).CreateSingleValue
NewValue.Value="1234"
reportInterface.ReportParameters.Item(1).CurrentValues.Add NewValue
iStore.commit result2
-
but I can't use selection formula
Any help????
Thanks!!
