Kurt Kennett from the Windows Devices Core team gives us a quick video that demonstrates a useful debugging trick: recovering the source of a “jump to NULL” error on Windows CE.   This is a very useful trick for debugging programs that use function pointers.

First, Kurt shows how to develop a sample application on the Device Emulator that will produce such a crash.  Then he shows how to get our precious callstack back!

This session has been presented at various Windows CE events such as MEDC.  It walks you through getting drivers from CE 5.0 (or previous versions) to work in CE 6.0.  Using the WaveAPI driver as a example, we look at the code necessary to move a driver with complex memory management forward into CE 6.0.[more ]
