Call to a .NET method inside a FOR EACH

Posted by jquerijero on 09-Sep-2013 11:51

I have a call to a .NET method (using a class inside a custom .NET dll) inside a FOR EACH. For some reason, the record in scope goes away after the call to the .NET method.

Any ideas?

What kind of method call is it? Is the call related to repositioning a Query using the Progress.Data.BindingSource?

There are problems with using methods inside FOR EACH blocks. See articles 000016292 and 000029112 in the knowledge base.

There is really nothing special about the for each.

FOR EACH bfttso_detail WHERE

            bfttso_detail.lDisplayOnCCDevice BY bfttso_detail.display_seq:

     IF cLine = "" THEN

       cLine = bfttso_detail.cCCDeviceOutput.

     ELSE

       cLine = cLine + CHR(3) + bfttso_detail.cCCDeviceOutput.

    ar.CreditCardPinPad:CCInterface:SendRequest(Dmsi.Agility.Payment.Commands:LinesDisplay, cLine).

     /* This fails. Record is no longer available. */

     ASSIGN

       bfttso_detail.lDisplayOnCCDevice = NO

       bfttso_detail.cCCDeviceOutput    = "".

END.
