如何得到Windows的用戶名稱和產(chǎn)品序列號呢？
1. 可以用 WNetGetUser() 這個(gè)函數(shù)來得到 user name;
2. Windows 95 的產(chǎn)品序號可以用 TRegistry 到 Registry Database 中找出來;
// 取得用戶名稱
function GetUserName: AnsiString;
var
lpName: PAnsiChar;
lpUserName: PAnsiChar;
lpnLength: DWORD;
begin
Result := '';
lpnLength := 0;
WNetGetUser(nil, nil, lpnLength); // 取得字串長度
if lpnLength > 0 then
begin
GetMem(lpUserName, lpnLength);
if WNetGetUser(lpName, lpUserName, lpnLength) = NO_ERROR then
Result := lpUserName;
FreeMem(lpUserName, lpnLength);
end;
end; { GetUserName }
// 取得 Windows 產(chǎn)品序號
function GetWindowsProductID: string;
var
reg: TRegistry;
begin
Result := '';
reg := TRegistry.Create;
with reg do
begin
RootKey := HKEY_LOCAL_MACHINE;
OpenKey('Software\Microsoft\Windows\CurrentVersion', False);
Result := ReadString('ProductID');
end;
reg.Free;
end;
