Save data upto completion

[gireesh]

Hai I had 9 vi's. Each one is linked through system exec. From starting to end each data should save in one file. Each vi showing in different window. How to append each data in one file

Do you mean you want to save all the output from the 9 vis to the same file?

[gireesh]

Yes, exactly

[muks]

Did you try it out? are you getting any error?

Can I Export Strings of Multiple VIs to the Same Text File?

[gireesh]

I didn't try it. I have no idea how to connect these data to a single file

After seeing this message thread, and your other one, I am wondering what you are doing that relies so heavily on your use of the SysExec function.

What are you doing?  What is requiring you to use SysExec?  Give us a big picture explanation of your project and not just these different questions about different details that use SysExec.  I'm getting the feeling you are going down a path that is making things far more complicated than they really should be.

Actually I am in a travel.i am sending through mobile. So I cannot try this and the link. I read the link. Once I tried spreadsheet with append file. but it saved as different file and named as 001,002 etc. Sysexec was used at the end me the program for calling the next program. I saved the programs in exe form. That's why I used sys exec.

That really didn't clarify anything.

"Once I tried spreadsheet with append file. but it saved as different file and named as 001,002 etc"

You tried onc?.  Maybe you should have tried a few more times.  If something wasn't working right for you there, then you should have tried solving that problem.  Sequential files sounds like something you might get from using an Express VI to create the files.

How would creating different .exe programs help that problem?  Stringing together multiple .exe 's by way of SysExec in LabVIEW really sounds like a hacked up program.

hi gireesh,

  Why dont you place each vi in a flat sequence/stack sequence and what ever the string outputs you are getting ,concatenate and at the last frame you write the whole concatenated string in a text file.?

Thanks and regards,
