"if you try to idiot proof your UI, they will build a better idiot..." I foresee myself quoting this many times in the future... -D

QUOTE (BOBILLIER @ Mar 23 2009, 05:13 PM) So what speaks against making your LabVIEW application work in the format that the current user is using? LabVIEW's string conversion function give you every power to do that. If you know you need to deal with decimal point (for instance instrument communication) then disable the "use system decimal point" input at the string nodes or prepend %.; to all format strings for Format into String and Scan from String. If however you write out data to disk or whatever, such as a spreadsheet file to be read by the other application then just leave it as is and LabVIEW will use whatever is the current user setting for the decimal point. Don't try to outsmart your end user. They seldom can appreciate that . Instead make your application work as best as possible in the environment your users work. It may seem like a lot of a hassle to do what I explained above and after the fact it can be indeed quite a bit of work. But once you stick to this rule it does in fact not cost you any more work as it will get second nature to consider at all string formatting places if you do need a specific format or instead want to go with whatever the user has currently selected. It always depends who will be the other device/application dealing with the data. Rolf Kalbermatter
