Windows logon name?

[inetd]

How can I get the current logon user name(including the domain name)? Any API?

e.g. mydomain\myusername

Thanks.

You may use environment variables "USERNAME" and "USERDOMAIN".

Thanks rpet.
Can you tell in more detail? How should I use these environment variables?

Thanks again.

Read their values via API function

GetEnvironmentVariable()

.

I had a problem using the environment variables some years ago.
On a company network the variables were cleared for some reason, probably by the login script.

I had to use the GetUserName API to get the user name.

Create a new form with one button and one label. Do not rename either.

In the 'on-click' event for the button type the following code so the whole event looks like this.

//----------------------------------------------------------void __fastcall TForm1::Button1Click(TObject *Sender)
{
DWORD dwSize = MAX_PATH+1;
char szBuf[MAX_PATH+1];
szBuf[0] = '\0';
GetUserName(szBuf, &dwSize);
Label1->Caption = szBuf;
}
//----------------------------------------------------------

When you click the button, the PC's username appears in the label. Viola!
