To use this function you must first write a C function specifying the display or print format for the report. You then must point to your C function by using the It_SetDumpHook function. For more information and an example, see Listing Screen and Control Information.

The information provided includes:

• The id of the screen (the iModal member of the IT_SCREEN structure)
• The name, value, left, and top members of the IT_CTRL structure

The ItEv_DumpEvent function displays a larger set of information: it lists all of the items on the screen associated with the current event, not only controls.
