Enable debug logging

Often, it's necessary to pinpoint exactly which PowerBuilder code was executed that caused the crash. Generally, you can use IDE to debug to locate the issue. If IDE debugging fails to locate the issue, you can try using “pbdebug.”

  • Use the /pbdebug command to run the application. For example, yourapp.exe /pbdebug

  • A *.dbg file will be automatically generated in the directory where the EXE file is located. After reproducing the crash, examine the last line of this dbg file, and then find the corresponding PowerBuilder code in the source code of the PowerBuilder application.

  • The *.dbg file records the filenames and version numbers of the DLLs currently loaded by the application, which can be used to determine whether it has loaded a mismatched DLL file.

    Note: pbdebug in complex applications can significantly slow down performance. In such cases, consider alternative methods, such as logging suspicious code to a file.
