filename spaces

[PReitano]

Hi,

Is matched pattern.vi a good way to check for spaces in a filename?
I am verifying the filename that the user enters has spaces or not.

Yes that is a good way of doing it.  If the string contains spaces, the offset past match will be greater than 0.  If no spaces, offset past match will be -1.

The Match Pattern function will work fine in this case, but it is overkill.  If you're just looking for the presence of a specific character, you could use the Search/Split String function, available in the String > Additional String Functions subpalette.  You can use the same method with this function of checking to see if the offset is less than zero, but this function will be more efficient since it only matches characters, not patterns (which require LabVIEW to do more work internally).

Something tells me I am going to get a lot of milage out of this little nugget.

Glad to help, Ben.  Maybe at some point I'll start posting a "weekly nugget" on the LabVIEW forum...I got a million of 'em.
