Sorry, you're not.

You can't pass an AnsiString as a parameter directly.  The function expects
an actual buffer instead.  You can do one of the following instead:

    char buffer[MAX_PATH+1] = {0};
    GetEnvironmentVariable( "PATH", buffer, MAX_PATH );
    oldPath = buffer;

Or:

    AnsiString oldPath = AnsiString::StringOfChar(' ', MAX_PATH);
    GetEnvironmentVariable( "PATH", oldPath.c_str(), MAXPATH );

Same here.  You can't pass an AnsiString directly, you need an actual
buffer.  In this case, you can pass in the return value of the c_str()
method.

    SetEnvironmentVariable( "PATH", newPath.c_str(), newPath.Length() );

>   SetEnvironmentVariable( "PATH", oldPath, oldPath.Length() );

Same here as well:

    SetEnvironmentVariable( "PATH", oldPath.c_str(), oldPath.Length() );
