how to find out where the exe file was installed?

[brunogp]

Hi there,

I have the following problem: In my VI, I'm reading a .txt file through the vi "Open Config Data" in which I specify the path of the txt. file and it returns me a refnum that is used to read the file. When I made the installer to this application, I included this txt, thus, the txt is kept together in the directory where the application is installed. The problem is that the path that is specified to the vi "Open Config Data" is not valid anymore, since the instalation directory is different. I'd like to know if there's a way to know where the application was installed. Maybe through a registry? If you have a suggestion, I'd be glad to hear it.

Kind Regards,

Bruno Ponne

Use the Current VI's Path function. Please note that the relative path to the file will be different in the EXE than in the development environement. See the first documents on this link for more details. The VIs in this document will allow you to solve your task very quickly.

In addition to the information that JB provided, you can also do something like what is shown in the attached VI that I use. It takes the approach of stripping the current VI's path till it gets to something that doesn't end in .exe, .llb or .vi. This will give the OS path regardless of where the VI is located. I find this useful because I sometimes build applications utilizing a library of plugins and, depending upon where the plugin library is located, the path to it may not be the same things as the path to the executable.

Thank you,

I guess this function will solve my problem.
