I need a way to figure out in LabVIEW 6.1 if LabVIEW is the "active"
application in Windows. More specifically, I need to know if a user
has switched to some other application besides LabVIEW. This needs to
work on an EXE as well as VIs.
I've submitted the VIs to Developer Zone and they are currently
undergoing a routine internal review before they become "live" (I'm an
NI employee). Hopefully it will be in the next couple of days. You
might want to search on "MD5" in Dev Zone over the next week or so as

I've submitted some MD5 VIs to Developer Zone that should become live

changing the default port configuration from 8/16 to 32-bits.

If you have the data in a table all you need is to split the table
into the X and Y parts (using the index array function) and then, if
needed, convert the value to a numeric (the timestamp might e.g. need

If it's a boolean you just put the VI inside a case and wire the

Looks like a bug to me.
One suggestion (a lot of work!) is to use a string control with an event
structure. You can trap what is entered and then write back the value in the
desired format using the Format Date/Time String function (which works).

Greg,
If you go to the Format and Precision sub-menu and select Advanced Editing
Mode for Relative Time, you can edit the format string to be "%.0t" which
will convert 100 (sec.) to 01:40 and automatically add hours as necessary.

There is a one option in LV. You can save your VI configuration. I

There is small problem in program or in me, it won=B4t save the formula.
