问题描述

我正在尝试使用JNA来显示一个名为MyWindowTitle的窗口.

I'm trying to bring to front a window named 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.

推荐答案

检查函数的拼写.您可以使用依赖关系遍历器来查看该函数是否存在于dll中.

Check the spelling of your function. You can use dependency walker to see if that function exists in your dll.

Ps:当我打开user32.dll时，这些就是我发现的功能

Ps : when I opened user32.dll those are the functions I found

:FindWindowA,FindWindowExA,FindWindowExW,FindWindowW
