When utilizing the 4D Ajax Framework and Developer Defined Windows, you may at times want to obtain the currently selected record from a Portlet. You can do this with a few simple DDW calls and then a check to make sure there is a record in place. Your code could be similar to the following:


ARRAY LONGINT($Recordnumber_al;0)
C_POINTER($TablePointer_p)

$TablePointer_p:=DAX_Dev_DDW_GetAttributes ("TablePointer")
DAX_Dev_DDW_GetAttributes ("RecordNumbers";->$Recordnumber_al)

If (SIZE OF ARRAY($Recordnumber_al)>0)
     GOTO RECORD($TablePointer_p->;$Recordnumber_al{1})
     If (RECORDS IN SELECTION($TablePointer_p->)>0)
          ` you have a record to work with!
     End if
End if
