Simulating a lost device

Minimizing should do the trick... I think.

Just tried that again to make sure - didn''t cause a failures/lost device.......

Try re-sizing the window. The change in window size will cause the device to be lost.

This page talks about what can cause a device to become lost. Judging from what it says, I would suggest simply calling Reset() with invalid parameters.

int main() { return *((int*)0); }

Thanks Agony - sometimes it helps to go back to the manual:

"By design, the full set of scenarios that can cause a device to become lost is not specified. A typical example is a loss of focus, such as when the user presses ALT+TAB or a system dialog is initialized"

Hitting Ctrl+Alt+Del brings up a system dialog, which does the trick - so Ctrl+Alt+Del then Esc is a very quick n'' easy way to lose the device in windowed mode.

Thanks for the input!
