Resolved Importstring distorts dw display

I upgraded an application from PB 8.0 to 2019 R3. There are two dw's in the scenario. The first dw does the retrieve and the second dw uses an Importstring to pull in the data from the first one:

dw_second.importString(dw_first.describe("datawindow.data"))

No errors are returned on the import but the presentation of the second dw has the controls on top of each other (screenshot attached). It works fine in PB 8.0

Any help would be appreciated!

Since you are currently performing a Describe("DataWindow.Data") followed by ImportString, I can assume the column specifications in the two DataWindow objects are the same? If so, you could try using RowsCopy. Depending on what the second DW is being used for, maybe ShareData would be a workable alternative.

Best regards,
John

You could try different things:

  • dw_second.SetRedraw(FALSE) before the import and dw_second.SetRedraw(TRUE) after the import
  • dw_second.GroupCalc() after the import

Hope that one of it helps.

Hi René ... Yes, A GroupCalc() command may be required after any DW Import, Copy, Direct Buffer update, etc. That has always been a requirement in order to get the DWO to "redraw" it's work area 100%. The Retrieve() does that for you BTW.

Regards ... Chris
