Name of new files

[Sarah83]

Hi,

I like to create a kind of log file after before my LV programm is closed (only if a failure exists).

The first log file was OK, but now I notice that the file names of the created log files must be expedient for later checks. My idea is, give the files a standard name e.g. log error messages. Then add the current date and time to this file name.

But how can I manage this? :headbang:

Hi,

I supposed you can put the name of file with the code error, with the tool unbundle by name you can selected the error code, and then convert to a string with Number to decimal string. So you are able to put this string in a name of file.

sorry for my bad english

Oh, I just find an icon which can convert a path to a string

I used my builded date and time sting connect this with link strings. This string is able to connect at standard name from open/create/replace a file (there I used <create> but I get a dialog which I don't want)

Hi!

I have still problems with replacing a string.

I find an example in the LV help about this - "search string and replace.vi"

I built the same code in my vi and test it. But there is no change. The same stings comes out as the string which go in :headbang:

So I take the example, made a sub vi and paste it in my code.

Second test. I saw how the string goes in, the string was displayed in "string in". Then the character to replace and the new character were set. After this the replaced string was displayed in "string out".

But at the end the unreplaced string comes out

I will replace a : with a _. In the time/date string I build the time is displayed like this: 09:20. And windows don't like : in a path name :headbang:

What can be the problem?!

Hi,

you see the result of terminal offset past replacement? i think the character ":" is one of the Codes are enabled to show nonprinting characters and if you try on the example search string and replace.vi the character "\" don't replace

you can convert your time for seconds and you loose the problem":"

Just wondering (also happens to me sometimes) if you accidetally wired the input of your replace-subvi instead of its output?

Another possibility: if you have the timestamp as either seconds timestamp-type then you can wire it to the Format Date/Time String in the Time & Dialog palette.

You can also use this function if you just want the actual time, then do not wire the input timestamp.

Hmmm, but inside of the example vi, it will replace this character 

But I don't get this replaced sting out, I only see it in the string display field "string out"

Can you post an image of your diagram where this VI is used? It looks like your "replace.vi" is working fine from what I can see on the front panel. How is this VI used in the caller?

Hi Michael,

here a screenshot.

Yes, I think the problem isn't in the "replace.vi", too.

Hi Sarah

is it possible to do another screen shot with a probe set before and after your un named vi :headbang:

ie just before your last concatenate string

This sub vi is the "replace.vi"

Which string do you mean? Before the case? :question:

Hi Michael,

thanks! :worship:

Now I understand why I must search and replace the string in two times

...ok, I will try to replace the ":" with a "_"....

I don't know, I can try this out if I have some time. It would be a shorter way.

Doh! Thanks Alex, this is what I should have recommended. . I use that in my programs as well. It slipped my mind.

Hey, at least this shows you read all the posts...
