own ini file is not referenced when I build an .exe file ??

[balucharly]

Hi there,

i have a application which uses a vi. This vi reads some parameters from a file to the application.

When I build a exe file the path to the .ini file is empty ? an error occurs.

What can I do to solve this

The structure is as following

- main.vi
- sub folder: - get_from_ini_file.vi
- file.ini


get_from_ini.vi searches in the same directory as it is itself, but when I build an exe file it doesn't work,
I debugged where it searches for the file, and the path was empty?

I'm using LabView 6i

Thanks for help of any kind.

This is a mistake everyone seems to make when they first use the app builder. The path to a built VI is different. For example, in the development environment, the path might be c:\folder\example.vi but with a built VI it will be c:\folder\app.exe\example.vi. The fix is to add an extra strip path. You can have your VI work in both development mode and as a built app by using a property node app.kind. It will return invalid, development system, run time system, etc., so you can wire the output to a case structure that does the extra strip path.

Hi Dennis,

how can I do this, what you explain. I'm using a node which returns me the actual path of the vi, in the same folder is the .ini file so it should be independent where the vi is stored.

But I believe you that my solution will not working, but I do not understand how to change it, that it works.

Must I add the /app.exe/ in the path? but the path I get is empty?

Could you please change my vi as you think that it should work? I do not know witch nodes I have to use, that it works.

Thanks for your help

You have to stripp the additional app.exe when running in the Runtime system. There's a property node which you can test for the actual environment. If this yields a Run Time System you just do an additional "split path"...


I hope that helps a bit,

Here's a picture of what I mean. I can't save your VI to version 6. The function does return the path of the VI but like I said, the path is different when built. It is no longer in the same folder as the ini file. It is part of the exe file (which is really an llb).
