Read application directory

[ARC-Tech]

I am writing a program to be compatible with two Vector Network Analyzers from seperate companies (this makes the GPIB commands incompatible).  I would like to place a configuration file in the same directory as the application); this program will tell the program which netwrok analyzer it is attached to, and therefore which set of commands to utilize.   The program will know to look in the directory in which the application resides to find this configuration file.  Is there a VI, or a set of code that I could use to find this directory programmatically and therefore find the configuration file?

I am using Windows XP Professional Service pack 2 with LabView 8.2

I don't have sure. Are you just asking how to do the following that I've on attached files?

[ARC-Tech]

That is what I needed, I actually figured it out right after I posted.

Thank you!

Just a quick note. I have a VI that does what was posted in 11.png. It strips 2 levels off the current VI's path. I place this in a subdirectory one level below my main VI. This way it will always return the main directory of the program, whether it's being run in the development environment or as an executable.

A small point, but something to make this task a little easier for any program you make.

Versus having to wire the boolean for executable or not, look at the attached.

I use the property node Application>>application>>kind.

This is a run-time method for determining if the application is a build Exe, or a VI.

A concept that I have been using for several years is the idea of a "Dynamic Instrument Driver". The basic purpose of a DID is to perform a particular instrument function - say, set the output of a power supply, or read a voltage or audio signal level. The driver itself is a shell for dynamically linking to a subVI that actually performs the desired operation. The subVI that gets called is dependent upon what instrument is installed in the system for that particular function. The thing that really makes everything work well is that all this configuration information is maintained in a database.
