[HWND的本地@ 0xc41bcc输出到实际窗口ID

Question

嘿，我在尝试使此JNA findwindow正常工作时遇到了问题，该问题给了我Windows ID（HWND）而不是一些疯狂的输出（native @ 0xc41bcc）。

我从使用C＃的工作中知道，当使用findwindow时，它将给出该找到的窗口的ID，然后我可以将其用于移动/调整/调整该窗口的大小。

我的代码：

public String exec(ITestExecutionServices tes, String[] args) {
        try {
            writer = new PrintWriter("c:/temp/the-file-name.txt", "UTF-8");
        } catch (FileNotFoundException | UnsupportedEncodingException e1) {
            e1.printStackTrace();
        }

        try {

            final User32 user32 = User32.INSTANCE;

            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            user32.EnumWindows(new WNDENUMPROC() {
                 @Override
                 public boolean callback(HWND hWnd, Pointer arg1) { 
                    byte[] windowText = new byte[512];
                    user32.GetWindowTextA(hWnd, windowText, 512);
                    String wText = Native.toString(windowText);
                    wText = (wText.isEmpty()) ? "" : wText;

                    if (wText.toLowerCase().contains("- funct test -")) {
                        writer.println("text: " + wText);
                         writer.println("HWND: " + hWnd);
                        //User32.INSTANCE.SetWindowPos(hwnd, new HWND(Pointer.createConstant(HWND_BOTTOM)), 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);
                         WinDef.HWND hwndFound = User32.INSTANCE.FindWindow(null, wText);                        
                         writer.println("hwndFound: " + hwndFound);
                         writer.println("t/f: " + User32.INSTANCE.MoveWindow(hwndFound, 500, 500, 10, 100, true));
                         //User32.INSTANCE.SetWindowPos(hWnd, new HWND(Pointer.createConstant(HWND_BOTTOM)), 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);
                    }

                    return true;
                 }
              }, null);
        } catch (Exception f) {
            String tmp = f.toString();

            for (StackTraceElement el : f.getStackTrace()) {
                tmp = tmp + System.getProperty("line.separator") + el.toString();
            }

            JOptionPane.showMessageDialog(null, "ERROR!");

            return "false";
        }

        writer.close();
        return "true";
    }

我认为这可能有所帮助：

import com.sun.jna.Pointer;
import com.sun.jna.platform.win32.User32;
import com.sun.jna.platform.win32.WinDef;

和此功能：

public long getWindowId(String title) {
  WinDef.HWND hwnd = User32.INSTANCE.FindWindow(null, title);

  return Pointer.nativeValue(hwnd.getPointer());
}
