找不到Java JNA sendMessage() [英] Java JNA sendMessage() not found

问题描述

我正在尝试使用 JNA SendMessage A(hW，0x0201，0，0);

I'm trying to use JNA (Overview) to send messages to an application when minimized or not on top (mouse click for example), and the I found that people are using com.sun.jna.platform.win32.User32.SendMessageA( hW, 0x0201, 0, 0);

但是我在此类中找不到此功能.

But i can't found this function in this class.

如果我做错了，有人可以给我一个例子来实现它吗?

Can someone give me an example of how to implement it if I'm doing it wrong?

代码:

User32 user32;
Pointer hW = user32.GetForegroundWindow().getPointer();
user32.SendMessageA( hW, 0x0201, 0, 0 );

推荐答案

public interface User32Ext extends User32 {
User32Ext USER32EXT = (User32Ext) Native.loadLibrary("user32",

        User32Ext.class, W32APIOptions.DEFAULT_OPTIONS);

HWND FindWindowEx(HWND lpParent, HWND lpChild, String lpClassName,
        String lpWindowName);

HWND GetTopWindow(HWND hwnd);

HWND GetParent(HWND hwnd);

HWND GetDesktopWindow();

int SendMessage(HWND hWnd, int dwFlags, byte bVk, int dwExtraInfo);

int SendMessage(HWND hWnd, int Msg, int wParam, String lParam);

void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

void SwitchToThisWindow(HWND hWnd, boolean fAltTab);

}
