1. PB2022 R3 3356 Powerclient incremental build .NET

   Hi

   PB2022 R3 3356 PowerClient incremental build

   - Everytime I rebuild my application from IDE with Rebuild: Incremental then all .NET calls in the deployed application fails with LOAD FAILURE (-1) generic error in of_createondemand() at row:

   ll_status = lnv_assembly.LoadWithDotNet(This.is_AssemblyPath)

    

   Only incremantal build seems to be affected. Full build works well.

    

   Have you noticed this strange behavior? It seems that some reference is missing there but only in incremental build.

2. Recovering a deleted object

   My PowerBuilder 2019 workspace is using git as source control system.

   I just deleted a datawindow object inside a pbl with right click on object -> delete.

   If I open a cmd on the folder I can see the object is deleted, but the delete is not commited or pushed yet:

   git status |grep d_test
           deleted:    ws_objects/proj_obj/proj_obj.pbl.src/d_test2.srd

   Is there a way to undo the delete?

   I migrated our client's application from PowerBuilder 2017 32-bit to PowerBuilder 2022 64-bit, the below code are under Local External Functions declaration in a user object, the below code can successfully run in PowerBuilder 2017 32-bit, but after I migrated to PowerBuilder 2022 64-bit, it causes error when call the below external functions in the code, what should be changed for the below code?

5. No "Invalid DW row/column specified" error for row 0

   Hello,

   I started noticing quite some time ago (maybe in PB 12.5, maybe earlier) that PB stopped throwing an error when GetItemX datawindow method is called with row 0. Now, when it happened again in PB2019 R3, I decided to isolate the issue. I created a simple DW with an external data source, one string column "s", and data "ABC". I placed a DW control on a window, and wrote the following datawindow control clicked event script:

   messageBox( 'Data in clicked', getItemString( 0, 's'))
   

   When I run the window and click the DW, I get a nice message box:

   

   If I misspell the column name, however:

   messageBox( 'Data in clicked', getItemString( 1, 'sss'))
   

   I still get the good old Invalid DW row/column specified error:

   

   Of course, if both row and column are correct, I get "ABC":

   messageBox( 'Data in clicked', getItemString( 1, 's'))
   

   

   Does anybody know why this is happening?

   Best regards,
   Konstantin
