关于C语言窗口隐藏的问题
本帖最后由 --_--|| 于 2024-7-4 23:13 编辑本人想做一个便携工具，目标是无参数运行时进入配置界面，有参数时进入运行参数命令。
想做到在配置界面时窗口正常显示，而带参运行时窗口隐藏
本来用#pragma comment(linker,"/subsystem:\"Windows\" /entry:\"mainCRTStartup\"")宏定义可以完美隐藏，但不知道怎么再把窗口调出来
而用ShowWindow()可以做到自由隐藏和显示，但开始会出现cmd窗口闪一下才隐藏
今天特地来问问各位鱼兄，有没有好办法可以实现这个效果，感谢！！！{:10_254:}

This Is An Example

#include <iostream>
#include <Windows.h>
//#pragma comment(linker,"/subsystem:\"Windows\" /entry:\"mainCRTStartup\"")//宏定义隐藏窗口

嗯，好的，谢谢大佬{:10_297:}
