在lua中使用os.execute时如何避免弹出窗口 [英] how to avoid popup a window when use os.execute in lua

问题描述

我正在使用os.execute()调用Lua中的其他程序，当程序运行时，cmd窗口会突然闪烁，并且我调用了execute超过100次，这变得很烦人. 那么有什么方法可以将窗口设置为不可见?

I am using os.execute() to call other program in Lua, when program run,the cmd windows will popup for a blink, and I call the execute more than hundred times, and it become annoying. So is there any way to set the window invisible?

推荐答案

简短的答案是hjpotter在评论中给出的: 不，你不能 .

The short answer was given by hjpotter in a comment: no, you can't.

随后将进行更详细的解释.

A longer explanation follows.

在Windows上，可执行文件具有两种形式": GUI应用程序和命令行应用程序.这与程序的内部工作无关，但取决于程序的构建方式(PE可执行标头中有一个标志，可以使用链接器选项设置该标志).当执行命令行应用程序时，操作系统会自动弹出控制台窗口(丑陋的黑匣子").

On Windows executable files come in "two flavors": GUI applications and command line applications. This has nothing to do with the inner workings of the program, but it depends on how the program was built (there is a flag for it in the PE executable header which can be set using a linker option). It is the OS that automatically pops up a console window (the "ugly black box") when a command line application is executed.

os.execute的问题是它使用C system功能，它可能又是通过执行Windows命令外壳可执行文件cmd.exe来实现的，该可执行文件是命令行应用程序.因此，每次使用os.execute时，实际上都在执行cmd.exe.黑框是与cmd.exe关联的控制台窗口.

The problem with os.execute is that it uses C system function under the hood, which in turn is probably implemented by executing the Windows command shell executable cmd.exe, which is a command line application. Thus every time you use os.execute you are indeed executing cmd.exe. That black box is the console window associated with cmd.exe being executed.
