FACT(s) (Environment):
OpenEdge 10.x
SYMPTOM(s):
Updated Temp-tables received from .Net client do not contain before-tables
Passing the DataSet as INPUT DATASET-HANDLE
Receiving the ProDataSet as a dynamic object (DATASET-HANDLE)
VALID-HANDLE(hBufferTT:BEFORE-BUFFER) returns FALSE
CAUSE:
The before-image flag has not be set on the .NET client side.
For a .NET DataTable, the client is responsible for setting the before-image flag with the ProDataTable static method SetBImageFlag().
The BImageFlag must be set for dynamic temp-table and ProDataset INPUT parameters to match the value of the BEFORE-TABLE attribute for the temp-table or temp-tables within the ProDataSet in the 4GL.
FIX:
Use the ProDataTable static method SetImageFlag()
The syntax is:
static void SetBImageFlag(System.Data.Datatable dt, bool flag)
where flag is true or false.
C# example:
ProDataTable.SetBImageFlag( myDataSet.Tables["State"],true);
