How i can get the needed information (for example value of string constants) from the VI file by open it for read in a automatical way?

[Yuri_IL]

Hi,

1. I have many VIs with string constants.

2. Every string constant holds vaule (for example "GPIB::11:MASK ON" or "SWITCH::POWER DIS")

3. I do not want to open all of files (about 2000 files) and in manual way explore the constants'values

4. I want with some VI or perhaps tool list the directory that will include all of 2000 VIs and to get some LOG / RESULT file with values of those constants

The questions:

1. Does it possible at alll???

2. What is the format of VI file? Does it open?

3. Any hints how i can do it? Any suggestions? Proposals??

Thank you very much,

                                     Yuri

I have not simple soluce but only a crazy idea :

Export VI as VI Strings (VI Method) then search for each text file the corresponding info such as :

<BDCONTENT>

<CONTROL ID=81 type="String Constant" >
  <DESC></DESC>
  <TIP></TIP>
  <PARTS>
   <PART ID=11 order=0 type="Text"><LABEL><STEXT>TEST</STEXT></LABEL></PART>
  </PARTS>
  <DEFAULT><SAME_AS_LABEL></DEFAULT>
 </CONTROL>

but I recognize it's long & delicate to develop it, surely very long in execution time...

It's only to help but I hope there exists a better way 😉

If i can export VI like STRINGS so i will can parse it!

Great idea! I did not know that we can represent VI like a STRING/XML format!

I will try it now!

Thank you alot!!!

tried   not working.  anybody able to ?

[J.DECHET]

Don't forget to specify TRUE as Export Diagram...

In fact, I used this method in the past to know in which version of LabVIEW was written a VI (first line of text file). I didn't find other method at this time...

But I prevent it's a very slow process and with your 2000 VIs you risk to wait a serious time.

Not so slow, i will LIST the directory and after it iteratively will send every file to CONVERTION without manual work 🙂

p.s. i suppose so ... 🙂

[J.DECHET]

Ok, it's true that today, computer's technologies are faster than when I practised it (one processor with slow hard disk, only 4 years ago)...

Question regards conversion:

I need instead REFERENCE to present file to find way how i can give a REFNUM of any OPENED file (such as i can iteratively to give the list of the files .. and not to

    manually seed it to every file...)

Any idea??? How i can do it?

Please see the attached picture of the issue

Thank you all!

[J.DECHET]

Use 'Open VI Reference' in the palette named "Application Control" instead of 'Open File' and don't forget to close it after... 😉

Hm i did it but now other program? Could you please the attached picture why it happens?

Thank you alot!
