write to measurement file - Create or replace with confirmation

[SuSto]

I'm using the "Write to measurement file.vi" and I want it to ask for confirmation if I try to save with a filename that already exists and then allow me to choose another file name or overwrite the old one. How can I do this?

[MoReese]

In this Express VI, select the box "Ask user to choose file."

I've done this. The only options it has are:

• Rename existing file—Renames the existing file if Reset is TRUE.
• Use next available name—Appends the next sequential number to the filename if Reset is TRUE. For example, if test.lvm exists, LabVIEW saves the file as test1.lvm.
• Append to file—Appends the data to the existing file. The VI ignores the value of Reset if you select the Append to file option.
• Overwrite file—Replaces data in an existing file if Reset is TRUE.

But I want to have it ask for confirmation to overwrite, then let you save it as a different name if you want. Is there any way to combine something with this vi to do this, or do I need to find another vi that would let me do this?

That Express VI does not have the capability you are seeking. You will need to either convert it to a regular VI and modify it, or simply add some code to do what you seek. THis can be accomplished quite easily with the File I/O functions.

Did I misunderstand the question again?

Your wording reminded me of the scene from Star Wars when Ben Kanobe di dthe force thing on the strorm troopers telling them "These are not the droid you seek."

Its just Friday.

Ah. Gotcha, Kimosabe.

Is there a way to combine the "write to measurement file express vi" with the "open/create/replace file" function? Or, more basically, is there a way to wire any file path through another function and into the "write to measurement" vi?

Of course, but you don't want to modify any LV functions (I don't know that you can).  This question seems so basic (too basic) perhaps I misunderstand what you are saying, but you can wire any reference through one of your VIs.
