Dump files

The User-Mode Dumps tab of the TPDU console offers the option to generate so-called Dumps, should program errors occur. In this event, the contents of the memory (RAM) are written into a file.

The page is divided into two sections:

  • Monitored Processes
  • Dump Files

Monitored processes

  • Using the Add Process button (arrow), you can select a Windows process to be moni­tored and then generate a User-Mode Dump if an error occurs. If you started the TPDU without administrator permissions, then the admin icon will be displayed on the button, indicating that the function will proceed with admin permissions.

  • A window will open in which you can mark the process or ‒ if it should not be active at the moment ‒ type it in (arrow). Leave the Include Page Heap option enabled, to include more information in the Dump file.
  • Click on Add to confirm. The relevant process then appears in the Monitored Processes list (see above).

Select the process to be monitored by mouse click or add it manually:

Dump files

If a monitored process produces an error (see Monitored Processes in the screenshot), then a User-Mode Dump is generated. This then appears in the Dump Files list (lower arrow). You can refresh the list with the F5 key.

This means there is no need to use GFlags (Global Flags Editor) from the Windows Debugging Tools. And, additionally, User-mode Dumps that originate from other sources are also dis­played here.
