Koji sve useri postoje ne znam kako a koji je trenutno aktivan, imaš ovaj dole napisani kod u basicu, možeš ga prevesti u C++ veoma lako:
Code:
Private Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function IsIconic Lib "user32" (ByVal hwnd As Long) As Long
Private Sub Form_Load()
Dim strTemp As String, strUserName As String
'Create a buffer
strTemp = String(100, Chr$(0))
'Get the temporary path
GetTempPath 100, strTemp
'strip the rest of the buffer
strTemp = Left$(strTemp, InStr(strTemp, Chr$(0)) - 1)
'Create a buffer
strUserName = String(100, Chr$(0))
'Get the username
GetUserName strUserName, 100
'strip the rest of the buffer
strUserName = Left$(strUserName, InStr(strUserName, Chr$(0)) - 1)
'Show the temppath and the username
MsgBox "Hello " + strUserName + Chr$(13) + "The temp. path is " + strTemp
End Sub
