LV Code challenge: How to realize the function of auto un-plug the USB Flash Disk by calling API of WinXP?

[waltersz]

Pls use version6.1!

That's not a LV code challenge. That's a windows code challenge.
You can call windows API functions by using the Call Library Function Node. You can find several tutorials for working with DLLs on this site. You can start here.

If you don't know how to work with USB devices in windows, then your problem is more basic. You should look for info about that first. You can try starting here.
I hope this helps.

I'll take a stab at it if you send me a USB flash drive to experiment with.;) Seriously, the best experts on windows api functions is at Microsoft's MSDN (though for some reason, I can't connect to it right now). There's also a bunch of comp.os.ms-windows newsgroups.

While it's nice to be regarded as an expert, I must tell you that it is definitely not "of course" that you know these things. You only wrote that you want to unplug the disk. You didn't say what your level of knowledge is and which things you already tried. Anyway, like Dennis (and my last link) said, this question is a windows question, so you stand a much better chance of getting an answer in a place that specializes in windows.

If you've managed to find the way to do this, but you have trouble implementing it in LV, then coming back here would be a good step. Also, if you find the way to do this, it would be nice if you posted an update here, in case anyone comes looking this in the future.
