How do I convert GetUserName to Lowercase?

[jlbess]

I'm using the following code in a C++ dll to retrieve the windows username of the current logged in user. I'm passing the username to a case sensitive application so I need to convert it to all lower case. Can anyone tell me how to convert acUserName to lowercase?

#include <stdafx.h>
#include <string.h>
#include <cctype>
#include <windows.h>

char acUserName[100];

DWORD nUserName = sizeof(acUserName);
GetUserName(acUserName, &nUserName);


Thank you

That's what this function is for. You will have to go through each character to check, though.

Another option could be using CharLower( ), this function has the advantage of taking into account the Locale of the windows user.

Worked perfect.

hi before converting that you have to use isupper() function it will tell whether that word contains uppercase letters or not.. then you can use charlower() function.
