jna x64的活動窗口進程名稱

我得到x86程序（在C：\ Program Files（x86））中所有需要的信息，沒有任何下面的語句問題。但對於活動窗口進程名稱的x64空結果。是否有可能檢測出與jna的x64處理器的活動窗口進程名稱（.exe路徑）？jna x64的活動窗口進程名稱

['GetWindowThreadProcessId']（http://msdn.microsoft.com/en-us/library/windows/desktop/ms633522（v = vs.85 ）.aspx）需要一個指向32位內存的指針。你給它一個指向一個指針的指針，這個指針是32位或者64位，這取決於你的平臺。然後，您將64位值傳遞給['OpenProcess']（http://msdn.microsoft.com/en-us/library/windows/desktop/ms684320（v = vs.85）.aspx），需要一個32位的值。 – technomage 2014-10-06 10:26:57

我得到用於x86和x64軟件的所有信息沒有任何問題，如果我將我的項目導出到可運行jar。上面的問題隻影響，如果我從Eclipse運行項目
