C++ - How to get the user folder?
c++, directory, vcl
Solution
One classic way is to read the environment variables using getenv:
char *user = getenv("USER");
char *appdata = getenv("APPDATA");
Regarding user rights and performing file read/write/create in these locations, you certainly can in the user folder the application is running as. In other folders, you'll need to run it as either the target user or administrator. Also, after installing an application in Program Files or Program Files (x86), the system will not allow you to write there. Installations are performed under the 'trustedinstaller' user credentials and the final user rights are set during installation for 'current user' or 'all users'.
Hope this helps.
Problem
I'm having a little problem with my program... I have to create a file with the application data, but I don't know how to access the `%USER%` or `%APPDATA%` directories... I've tried to use the application folder, but if I install the application in `D:\Program Files\(Organization)\(APPName)` I cannot write new files in this directory, I can just read or modify if I don't have admin privileges... So, the question is: How to access the %USER% folder or Get ADMIN privileges with the application... PS.: I'm using VCL in C++ Builder
