saving a v7.1 VI for use with v7.0

[WCR]

A colleague wants to use a VI I made in LV 7.1, and he would like access to the

block diagram for making changes  When he tried to open it with his LV 7.0, it

didn't work, so I tried "saving for previous version" for LV v7.0.  After the save,

I got a lot of warning messages, such as:

   BuildHelpPath.vi
     Virtual Instrument
       Cannot save VI from VI.LIB to previous version.
   Clear Errors.vi
     Virtual Instrument
       Cannot save VI from VI.LIB to previous version.
   Close File+.vi
     Virtual Instrument
       Cannot save VI from VI.LIB to previous version.
   Complex FFT.vi
     Virtual Instrument
       Cannot save VI from VI.LIB to previous version.

I don't understand this.  I'm sure all the functions (VIs) listed exist in

v7.0, so why the error messages?  How do I give him my VI,

which I think does not use anything that is v7.1-specific?  Thank you.

Just give it to him. As you state in the first paragraph, those are "warning messages" and not error messages. All it means is that those natvie LabVIEW functions exist in 7.0 and won't be saved to a previous version. When the 7.0 user opens your VI, the functions of the same name in 7.0 will be used.

OK.  Thank you, Dennis.
