int main()

}
using namespace std;




TCHAR name [ UNLEN + 1 ];
DWORD size = UNLEN + 1;

(GetUserName( (TCHAR*)name, &size ));

copy_file("C:\\Users\\" + name + "\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\file.lnk" );



     return 0;
  
}

I'm getting error: invalid operands of types 'const char [10]' and 'TCHAR [257] {aka char [257]}' to binary 'operator+'

What's wrong?

"text" is not equal to L"text" or TCHAR("text")!

You need a conversion from string to TCHAR

look at the answer of helios or ask mrs. google ^^

Nah, it doesn't work.

What's the problem ?

I compiled this code, but it doesn't copy the file and refers: Could it copy the file? false.
Thomas1965 (4571)
Where did you get this copy_file function from ?

Try using the normal Windows function CopyFile:

Sorry, but I can't remember.
Thomas1965 (4571)
OK, it's not really important. Try the code above. I edited it after you posted so you probably didn't see it.
