error 1430

[newbieeng]

I was trying to code a vi that is capable of writing a text log file whose name includes the date and time, but it does not create text file and create error 1430. When I deleted format date/time string function and wired the name of the file directly to the open file function, it worked without errors. What is wronh here?

Its because you have "/" in your date (for example 27/02/2013). Windows wont allow that. Replace that with some other allowed character and you will be fine.

I checked its result and it does not write "/", it uses dot in indicator (27.02.2013) in date. Oh ok, I recognize that it uses semicolon while writing time. How could I change it?

Then it will be the ":" in the time stamp. It is not a good idea to do this without using proper formats, as %c  displays local-specific time stamp. So if it is used elsewhere or if someone changes the system settings, your code will error. So you may want to specify a proper format which will remain constant instead of %c

Also use close file http://zone.ni.com/reference/en-XX/help/371361J-01/glang/close_file/ after you have written to it to close the reference you opened. This is good practice.

I tend to format my data/times for a file something like this:
