multiple monitor detection and positioning

i have a couple of examples from microsoft and vbaccelerator, using classes and APIs

the microsoft download would not run correctly on my machine as the API declare was not quite correct, maybe because it was written in VB4

i tried a simpler code getting the monitor info from the registry, i have only tested this using one setup, 2 monitors on a single video card, extended monitor to the left of and slightly higher than primary monitor

i would be grateful for any other test results, including registry info for test machines, if code fails to recognise the extended desktop

moving the form from 1 monitor to the other is not positioned exactly correct, but seems closer than some other code i tested
