I have a trace file .PBP and I’m trying to read it with the code below ( ‘read application’) :

 [---- more code ----]

ltan_node = ltf_file.NextActivity()
ll_activity_counter = 0
do while IsValid(ltan_node)
 ll_activity_counter++
 ll_delta_activities = 0
 ldc_delta = 0
 ls_object_id = ""
 if Mod(ll_activity_counter, 1000) = 0 then
   of_add_to_log("Verwerkt : "+ String(ll_activity_counter)+ ".")
   st_counter.text = String(ll_activity_counter) + " / " + String(ll_nr_of_activities)
   st_skipped.text = String(ll_skipped_activities)
 end if
 yield()
 ltan_node_next = ltf_file.NextActivity()
 
 [---- more code ----]
 
loop

The trace file is created with a PB19 business application .EXE.  I have a separate .EXE that is trying to read and process the .PBP file.

The PB19 version of this ‘read’ application is reading the first activity correct (NextActivity) and crashes on the second call to NextActivity.

Attached you will find the Windows Error Reports from the event viewer.

The PB22 version of this ‘read’ application is reading the first activity but this results in a null object and therefore not entering the loop.

When testing the business application with the PB22 IDE and creating a .PBP file, this .PBP is correctly processed by the PB22 ‘read application’.

The PB19 ‘read application’ crashes.

Is this expected behaviour?

The biggest problem at the moment is that the PB19 version of the business application creates a .PBP file that cannot be read a PB19 ‘reading application’.

Are there differences in .PBP file structure between PB19 R2 builds?
