Thread: Getting current user username

Hello,

I tried the code as follows:

Code:

   
#include <windows.h>
#include <stdio.h>
#include <Lmcons.h>
#include <string>
#include <iostream>
int main()
{
 char username[UNLEN +1];
    DWORD username_len = UNLEN + 1;
    GetUserName((LPWSTR)username, &username_len);
    for each(auto test in username)
    {
        cout << test ;
    }
}

Which shows me that I indeed have chars inside username.
Now I try to do the following as described here on the answer also but it doesn't work.

The problem by the compiler is on that line and specifically on variable username:

Code:

GetUserName(username, &username_len);

Error says: Argument of type "Char*" is incompatible with parameter of type LPWSTR.
So I change my code to this:

Code:

char username[UNLEN + 1];
        DWORD username_len = UNLEN + 1;
        GetUserName((LPWSTR)username, &username_len);

And when I print it, I only get the first letter. Why?

Thanks in advance!

Well I tried this one as well:

Code:

    wchar_t username[UNLEN +1];
    DWORD username_len = UNLEN + 1;
    GetUserName(username, &username_len);
    cout << username<<"\n";

Still isn't working..

Anyway, wcout fixed it

Code:

    wchar_t username[UNLEN +1];
    DWORD username_len = UNLEN + 1;
    GetUserName(username, &username_len);
    wcout << username <<"\n";

Thanks
