Java JNA FindWindow() - 查找函数“FindWindow”时出错：找不到指定的过程

我正在尝试将一个名为的窗口带到前面MyWindowTitle, using JNA.

import com.sun.jna.Native;
import com.sun.jna.win32.StdCallLibrary;
import com.sun.jna.platform.win32.WinDef.HWND;

public class ToFront {

public static interface User32 extends StdCallLibrary {
    final User32 instance = (User32) Native.loadLibrary ("user32", User32.class);
    HWND FindWindow(String winClass, String title); 
    boolean ShowWindow(HWND hWnd, int nCmdShow);
    boolean SetForegroundWindow(HWND hWnd);

}


public static void main(String[] args) {
    HWND hwnd = User32.instance.FindWindow(null, "MyWindowTitle"); 
    User32.instance.ShowWindow(hwnd, 9); 
    User32.instance.SetForegroundWindow(hwnd); 
}

}

我收到以下异常java.lang.UnsatisfiedLinkError: Error looking up function 'FindWindow': The specified procedure could not be found.

您可以使用以下代码调用 FindWindowEx。请注意，根据本文，FindFindow 不会搜索子窗口http://msdn.microsoft.com/en-us/library/windows/desktop/ms633499(v=vs.85).aspx http://msdn.microsoft.com/en-us/library/windows/desktop/ms633499%28v=vs.85%29.aspx
