//声明: GetWindowThreadProcessId(
hWnd: HWND; {指定窗口句柄}
lpdwProcessId: Pointer = nil {返回进程 ID 的指针}
):DWORD; {返回线程 ID}
第二个参数@变量获得进程ID,nil函数返回线程ID
procedure TForm1.FormCreate(Sender: TObject);
var c: Cardinal;
begin
GetWindowThreadProcessId(Handle, @c);
ShowMessage(IntToStr(c)); {2792; 随机的}
{在本例中相同于 GetCurrentProcessID 的结果}
c := GetCurrentProcessID;
ShowMessage(IntToStr(c)); {2792}
c := GetWindowThreadProcessId(Handle, nil);
ShowMessage(IntToStr(c)); {2748}
{在本例中相同于 GetCurrentThreadID 的结果}
c := GetCurrentThreadID;
ShowMessage(IntToStr(c)); {2748}
end; end.
