relative file names

[Eyecheck]

I want to have LV access a file of data but I want this done so that when
I use application builder and installer, it will know where to look for the
file. Currently I have an absolute reference to the file c:/test/data for
example. Is there a way to reference the file name relative to the folder
where the executable is located?

Two ways to do this.
1. Use "Current VI's path" and "Strip Path" to strip off two elements. This
will leave you with the folder that contains the EXE. Note this will return a
different path when used in the development environment.

2. In LV 5.x, use an Application Property node to return the
Application:Directory. In an EXE, it will return the folder that contains the
EXE. In the development environmen
t, it will return the folder that contains
the LabVIEW EXE.

In the Property node, there is also Application:Kind to determine if you are in
development or a built app.

Hey Brian,
I must be brain damaged as I cannot figure out how to do this with an
application:Kind thingy. Can you please describe in some detail how to
do this?

Thanks a lot!!!

In the File I/O Functions, underFile Constants there is a function
called "Current VI's Path" which should do as you want. It will
reference the path location to the called exe.

I have a problem in which I have created a command line utility that I
want to know what directory it was called from, not the directory of
the executable (which will be different in this case).

For similar purposes I have used the Win32 function GetCurrentDirectory (in
Kernel32) My subvi is attached. The return value is the current directory,
not the vi directory. Maybe this is what you're looking for?
