Hello ,

We are working on Appeon 2019 R3 version 64 bit but here problem is that debugger is not working as IDE is still on 32 bitand we hve external dll which move to 64 bit.

Do we have any external debugger which we can use to debug the code and find issues in the code as we are getting NULL pointer in one of the window and we are not able to find the exact function i.e from where it is coming ?

Problem with LenA function when migrating to PB19
PVBM.DLL cannot be loaded from C++

Hi.

The simplest thing I can think is to take a copy of the project, migrate it to 2022 R3, and check if the specific issue occurs there. If yes, then debug using 2022 R3 to see what is causing the problem...

Adding to what Andreas said, PB 2022 R3 has a 64-bit debugger whereas PB 2019 R3 does not.

Add this as a global external function:

Subroutine OutputDebugString( &
	string lpOutputString &
	) Library "kernel32.dll" Alias For "OutputDebugStringW"

Then go here and download the DebugView app:

https://learn.microsoft.com/en-us/sysinternals/downloads/debugview

You can add calls to OutputDebugString in your code. The string will appear in the DebugView app.

It is same as Messagebox("Information" ,"We are here")



I want such debugger which works same as internal debugger , trace every existing functions , shows which function , user object is invoking.

You'll have to follow Andreas' suggestion. Install PB 2022-R3, make a copy of your workspace, open the copy in PB 2022-R3, and run the debugger in 64-bit mode.

You can try to start your exe with the /pbdebug option.

But be warned. This can be really slow.
