如何从Java独立应用程序在前台打开Windows应用程序

Question

我想从Java代码运行基于Windows的应用程序，例如：

Runtime rt = Runtime.getRuntime();

Process pr = rt.exec("C:\MyWindowsApplication.exe");

此应用程序已正确启动，但是要知道如何确保MyWindowsApplication始终从Java应用程序在前台打开

我尝试使用jna库获取进程的PID编号，然后使用给定的PID编号运行VBScript以将Windows应用程序设置为前台。

预期结果是：如果我从Java中打开任何基于Windows的应用程序，则该应用程序应始终在前台打开。

Since you are using JNA already, you probably want to use the SetForegroundWindow function in the User32 class.

You will need a handle to the Window to use that function. You can use JNA's WindowUtils.getAllWindows() to get a list, iterate and match the title or filePath, and then call getHWND() on the matching window.
